Background: Neuropsychiatric disorders are common in 22q11.2 Deletion Syndrome (22q11DS) with about 25% of affected individuals developing schizophrenia spectrum disorders by young adulthood. Longitudinal evaluation of psychosis spectrum features and neurocognition can establish developmental trajectories and impact on functional outcome. Methods: 157 youth with 22q11DS were assessed longitudinally for psychopathology focusing on psychosis spectrum symptoms, neurocognitive performance and global functioning. We contrasted the pattern of positive and negative psychosis spectrum symptoms and neurocognitive performance differentiating those with more prominent Psychosis Spectrum symptoms (PS+) to those without prominent psychosis symptoms (PS−). Results: We identified differences in the trajectories of psychosis symptoms and neurocognitive performance between the groups. The PS+ group showed age associated increase in symptom severity, especially negative symptoms and general nonspecific symptoms. Correspondingly, their level of functioning was worse and deteriorated more steeply than the PS− group. Neurocognitive performance was generally comparable in PS+ and PS− groups and demonstrated a similar age-related trajectory. However, worsening executive functioning distinguished the PS+ group from PS− counterparts. Notably, of the three executive function measures examined, only working memory showed a significant difference between the groups in rate of change. Finally, structural equation modeling showed that neurocognitive decline drove the clinical change. Conclusions: Youth with 22q11DS and more prominent psychosis features show worsening of symptoms and functional decline driven by neurocognitive decline, most related to executive functions and specifically working memory. The results underscore the importance of working memory in the developmental progression of psychosis. [ABSTRACT FROM AUTHOR]

The radical imagination entails stepping outside the confines of the now and into the expansiveness of what could be. It has been described as the ability to dream of possible futures and bring these possibilities back to the present to drive social transformation. This perspective paper seeks to provide an overview of the radical imagination and its intersections with Afrofuturism, a framework and artistic epistemology that expresses the Black cultural experience through a space of hope where Blackness is integral. In this paper, I propose three processes that comprise the radical imagination: (1) imagining alternative Black futures, (2) radical hope, and (3) collective courage. I consider the neural networks that underlie each process and consider how the Black radical imagination is a portal through which aging Black adults experience hope and envision futures that drive social change. I conclude with considerations of what brain health and healing justice looks like for aging Black Americans-- specifically, how invocation of the Black radical imagination may have positive brain health effects for a demographic group at increased risk for Alzheimer's disease and related dementias.

Environmental sensitivity, which refers to the capacity to recognize and react to environmental stimuli, has been linked to increased levels of metacognition, which is the capacity to learn about one's own learning processes. Sensory processing sensitivity (SPS) is a characteristic that can make people more sensitive to the stimuli and settings in their surroundings. Regarding the development of mobile game-based educational procedures, the study of the neurocognitive bases of the mechanisms underlying them, such as metacognition and environmental factors, could play a crucial role in the implementation of these educational practices. The purpose of the current narrative review is to identify the key mechanisms by which mobile games affect young learners' metacognitive and environmental sensitivity profiles and to suggest future research directions on the specific selection of gamification-based educational interventions.

Background: Schizophrenia is associated with poor functional recovery. Internalized stigma is one of the factors related to the functioning of individuals with schizophrenia. We aimed to investigate whether internalized stigma was associated with subjective and objective recovery-related outcomes after controlling for neurocognition and other important confounders in individuals with schizophrenia. Method: We assessed the socio demographic background, psychopathology, neurocognition, internalized stigma, psychosocial functioning, and quality of life of 86 patients who had schizophrenia. Correlation analyses and multiple linear regression were used to investigate the association of internalized stigma and other variables with recovery-related outcomes. Results: We found that the negative symptom scores of the Positive and Negative Syndrome Scale but not internalized stigma was associated with psychosocial functioning as measured by the Personal and Social Performance global score. In contrast, internalized stigma was associated with the Psychological, Social relationships, and Environment scores of the World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF). Depression was also associated with the Physical health, Psychological, and Social relationships sores of the WHOQOL-BREF. Conclusions: While internalized stigma was associated with several domains of quality of life, it was not associated with clinician-rated psychosocial functioning. The effects of internalized stigma on the subjective and objective recovery-related outcomes of individuals with schizophrenia might be divergent. [ABSTRACT FROM AUTHOR]

Previous studies demonstrated neurocognitive impairments in early-onset schizophrenia (EOS) and other psychotic spectrum disorders (PSD). This study aimed to compare remitted and symptomatic cases in terms of neurocognition and theory of mind (ToM). 50 healthy controls (HC) and 106 patients diagnosed schizophrenia in remission (EOS-R, n = 38), symptomatic schizophrenia (EOS-S, n = 34), and other PSD (n = 34) were included in our study. The Positive and Negative Symptom Scale, Columbia-Suicide Severity Rating Scale, Reactive and Proactive Aggression Questionnaire were used to evaluate psychopathology. A cognitive battery was conducted to measure verbal learning/memory, visual learning/memory, executive functions (EF), inhibition, processing speed (PS), verbal fluency skills. Reading Mind in Eyes Test (RMET) and Faux-Pas tests were implemented to assess ToM. Principal Component Analysis was used to identify cognitive domain scores. Patient groups had poorer performance in cognitive domains than the HC group. The cognitive impairment and psychopathology levels of EOS-R and the PSD groups were comparable for all cognitive domains. The EOS-S group also had poorer scores in Rey verbal learning score (d = 0.87), RMET (d = 0.72), verbal fluency (d = 0.66), PS/EF (d = 0.82) and visual learning/memory (d = 0.83) test scores than the PSD group. Only RMET (d = 0.72) and executive function/processing speed domain (d = 0.63) were significantly impaired in the EOS-S group than the EOS-R group Cognitive impairments seen in remitted psychotic disorders were on the same continuum. Impaired EF/PS and ToM skills could be a cognitive marker for symptomatic illness in youth. [ABSTRACT FROM AUTHOR]

Aiming at discerning potential biotypes within the psychotic syndrome, we have recently reported the possible existence of two clusters or biotypes across schizophrenia and bipolar disorder characterized by their cognitive performance using the Brief Assessment of Cognition in Schizophrenia (BACS) instrument and validated with independent biological and clinical indexes (Fernández-Linsenbarth et al. in Schizophr Res 229:102–111, 2021). In this previous work, the group with larger cognitive deficits (N = 93, including 69 chronic schizophrenia, 17 first episodes (FE) of schizophrenia and 7 bipolar disorder patients) showed smaller thalamus and hippocampus volume and hyper-synchronic electroencephalogram than the group with milder deficits (N = 105, including 58 chronic schizophrenia, 25 FE and 22 bipolar disorder patients). We predicted that if these biotypes indeed corresponded to different cognitive and biological substrates, their adaptation to real life would be different. To this end, in the present work we have followed up the patients' population included in that work at 1st and 3rd years after the date of inclusion in the 2021 study and we report on the statistical comparisons of each clinical and real-life outcomes between them. The first cluster, with larger cognitive deficits and more severe biological alterations, showed during that period a decreased capacity for job tenure (1st and 3rd years), more admissions to a psychiatric ward (1st year) and a higher likelihood for quitting psychiatric follow-up (3rd year). Patients in the second cluster, with moderate cognitive deficits, were less compliant with prescribed treatment at the 3rd year. The differences in real-life outcomes may give additional external validity to that yielded by biological measurements to the described biotypes based on neurocognition. [ABSTRACT FROM AUTHOR]

Purpose: Multimodal therapies have significantly improved prognosis in glioma. However, in particular radiotherapy may induce long-term neurotoxicity compromising patients' neurocognition and quality of life. The present prospective multicenter study aimed to evaluate associations of multimodal treatment with neurocognition with a particular focus on hippocampal irradiation. Methods: Seventy-one glioma patients (WHO grade 1–4) were serially evaluated with neurocognitive testing and quality of life questionnaires. Prior to (baseline) and following further treatment (median 7.1 years [range 4.6–11.0] after baseline) a standardized computerized neurocognitive test battery (NeuroCog FX) was applied to gauge psychomotor speed and inhibition, verbal short-term memory, working memory, verbal and non-verbal memory as well as verbal fluency. Mean ipsilateral hippocampal radiation dose was determined in a subgroup of 27 patients who received radiotherapy according to radiotherapy plans to evaluate its association with neurocognition. Results: Between baseline and follow-up mean performance in none of the cognitive domains significantly declined in any treatment modality (radiotherapy, chemotherapy, combined radio-chemotherapy, watchful-waiting), except for selective attention in patients receiving chemotherapy alone. Apart from one subtest (inhibition), mean ipsilateral hippocampal radiation dose > 50 Gy (Dmean) as compared to < 10 Gy showed no associations with long-term cognitive functioning. However, patients with Dmean < 10 Gy showed stable or improved performance in all cognitive domains, while patients with > 50 Gy numerically deteriorated in 4/8 domains. Conclusions: Multimodal glioma therapy seems to affect neurocognition less than generally assumed. Even patients with unilateral hippocampal irradiation with > 50 Gy showed no profound cognitive decline in this series. [ABSTRACT FROM AUTHOR]

Background and Hypothesis Impairments in function (ie, the ability to independently accomplish daily tasks) have been established in psychotic disorders. Identifying factors that contribute to these deficits is essential to developing effective interventions. The current study had several goals: examine potential differential relationships across domains of neurocognition, assess whether reinforcement learning is related to function, identify if predictors of function are transdiagnostic, determine whether depression and positive symptoms contribute to function, and to explore whether the modality of assessment impacts observed relationships. Study Design Data from 274 participants were examined with schizophrenia/schizoaffective disorder (SZ; n = 195) and bipolar disorder (BD; n = 79). To reduce dimensionality, a PCA was completed on neurocognitive tasks which resulted in 3 components. These components and clinical interview data were used to investigate predictors of functional domains across measures of function (self- and informant-report SLOF and UPSA). Results Two components, working memory/processing speed/episodic memory (βs = 0.18–0.42), and negative/positive reinforcement learning (β = −0.04), predicted different functional domains. Predictors of function were largely transdiagnostic with two exceptions: reinforcement learning had a positive association with self-reported interpersonal relationships for SZ and a negative association for BD (β = 0.34), and the negative association between positive symptoms and self-reported social acceptability was stronger for BD than for SZ (β = 0.93). Depression robustly predicted self-reported but not informant-reported function, and anhedonia predicted all domains of informant-reported function. Conclusions These findings imply that reinforcement learning may differentially relate to function across disorders, traditional domains of neurocognition can be effective transdiagnostic targets for interventions, and positive symptoms and depression play a critical role in self-perceived functional impairments.

Recent research has focused on neurological soft signs (NSS) in bipolar disorder (BD), but there is still scarce evidence on their correlates with other relevant variables. The aim of this study was to explore the association between NSS and clinical demographic, neurocognitive, and functional variables. Eighty-eight euthymic BD patients were included in whom NSS were assessed using the Neurological Evaluation Scale. All subjects performed an extensive neurocognitive battery selected to assess premorbid IQ, attention, language, verbal memory, and executive functions. Psychosocial outcomes were assessed by means of the Functioning Assessment Short Test. Among the demographical variables, NSS tended to be negatively associated with years of education and increased with age. Likewise, NSS were higher in BD type I than in BD type II, but independent of age at illness onset and number of previous affective episodes. There was a negative correlation between NSS and premorbid IQ, as well as with performance in attention, language, and executive functions. Results tended to be unchanged when controlled for potential confounders. Although NSS were associated with poor psychosocial functioning in the bivariate analysis, when added to a multiple regression model including neurocognition, these neurological features did not significantly contribute to the variance of the functional outcome. Our findings contribute to a better characterization of NSS in BD; their potential clinical and theoretical implications are discussed in the manuscript. [ABSTRACT FROM AUTHOR]

Objective: This study compared and explored the neurocognitive profiles of siblings of persons with and without neurodevelopmental conditions (NDCs) and associations between objective test performance and self-reported psychosocial functioning. Methods: Siblings of persons with and without NDCs (64 NDC and 64 control siblings; mean age 19.88 years, range 11-27 years, 73.44% female, 75.78% White Caucasian) completed self-report questionnaires and self-administered computerized neurocognitive tests of executive functioning (EF). Using Bayesian analyses, we examined cross-sectional associations between self-reported psychosocial functioning and cognitive test performance, and predictors of EF over 15 months. Results: NDC siblings had poorer working memory, inhibition, attention, and shifting compared to controls, as measured by experimental paradigms on the backward Corsi span, N-Back 2-back task, Stop Signal Task, Sustained Attention to Response Task, and the Wisconsin Card Sorting Test (effect size δ ranging 0.49 to 0.64). Bayesian cross-sectional networks revealed negative emotion reactivity and working memory difficulties were central to the NDC sibling network. Over 15 months, poorer EF (k low test scores) was predicted by negative emotion reactivity, sleep problems, and anxiety, over and above effects of age and subclinical autistic and ADHD traits. Siblings of autistic individuals and persons with fetal alcohol spectrum disorder had higher rates of neurocognitive and psychiatric difficulties than other NDCs and controls (Bayes factors >20). Conclusions: Neurocognitive difficulties were associated with transdiagnostic vulnerability to poorer wellbeing in NDC siblings. These findings demonstrate the feasibility of remote online cognitive testing and highlight the importance of individualized prevention and intervention for NDC siblings. [ABSTRACT FROM AUTHOR]

Background: Chronic viral hepatitis is a systemic disease characterized by a wide range of extrahepatic manifestations, one of which is cognitive impairment. Aim and Objectives: To assess cognitive impairment in patients with chronic viral hepatitis at various stages of liver fibrosis and assess factors affecting cognitive dysfunction. Material and Methods: Two hundred thirty three patients with chronic viral hepatitis at the Infectious Diseases Hospital of Shymkent City and the Regional Hepatological Center of Shymkent City were enrolled between March 2021 and January 2022. All patients were surveyed on Montreal Cognitive Assessment (MoCA) to confirm the presence of cognitive impairment. Results: Mild cognitive impairment was detected in 12.7% patients with fibrosis stage F0 , at the stage F1 -20.7% of patients, at the stage F2 - 32.5% of patients, at the stage F3 - 36.8% of patients, at the stage F4 -40% of patients. Subsequent multiple regression analysis showed that older age (p < 0.023) and duration of the disease (p < 0.002) were the variables most closely associated with cognitive impairment. Conclusion: The early identification of cognitive impairment in patients with chronic viral hepatitis is necessary due to the high risk of their progression to the stage of severe cognitive deficit.

Abstract Background Once psychosis has set in, it is difficult for patients to achieve full recovery. Prevention of psychosis and early intervention are promising for improving the outcomes of this disorder. In the last two decades, neurocognition has been studied as a biomarker for clinical-high risk for psychosis (CHR-P). However, neurocognitive functioning has been under-investigated in adolescents. Methods We enrolled 116 adolescents from 12 to 17 years old (mean = 15.27, SD = 1.56; 76 females). This 3-year cohort study aimed to identify differences in neurocognitive and overall functioning in three groups of adolescent patients divided according to the semi-structured interview Comprehensive Assessment of At-Risk Mental States (CAARMS): adolescents with established psychosis, adolescents with CHR-P, and adolescents not meeting either criteria (non-CHR-P). To differentiate the profiles, clinicians administered cognitive evaluation and neuropsychological tasks. Moreover, they filled in scales to assess their global, social, and role functioning and a questionnaire to assess the severity of the disease. Results We made a between-group comparison on neurocognitive measures and found that the CHR-P and the psychosis groups differed in processing speed (TMT-A; p = .002 in BVN categorial fluency (p = .018), and Rey–Osterrieth complex figure drawing from memory task (p = .014), with psychosis group showing worse performance. No differences emerged between non-CHR-P and CHR-P (p = .014) individuals. CHR-P had better functioning than the psychosis group but worse than the non-CHR-P one. Conclusions These results confirm that neurocognition can be a helpful biomarker in identifying specific subgroups of adolescents with emerging psychopathology and help clinicians develop stratified preventive approaches.

Background: Clear localization (or) related deficits would make gateways for forming rehabilitation strategies much needed to enhance functionality in schizophrenia. We aimed to study the neuropsychological dysfunction including laterality in schizophrenia patients by using the native All India Institute of Medical Sciences Comprehensive Neuropsychological Battery (AIIMS CNB) in Hindi Adult form. Materials and Methods: In a cross-sectional study design, 40 right-handed schizophrenia patients in the age range of 18–59 years with primary education who can read and write were purposively recruited. Neuropsychological assessment and psychopathology were assessed by AIIMS CNB and Positive and Negative Syndrome Scale (PANSS), respectively. Raw scores and T-scores were recorded, and lateralization scores were calculated. The localization was estimated by commuting eight lobe scales. Statistical analyses of the quantitative scores were done using IBM SPSS 28. Results: The mean PANSS total scores and dose of chlorpromazine equivalents of the sample were 88.900 ± 9.940 and 497.500 ± 100.607 mg. 62.5% of the participants reportedly had the presence of brain dysfunction based on T-scores. Right hemispheric lateralization of cognitive deficits was present markedly in 95% of schizophrenia subjects. As per lobe scale scores, the right sensory-motor lobe (60%) and the right frontal lobe (27.5%) were found to be most dysfunctional. Conclusion: Majority of schizophrenia patients are dysfunctional as per AIIMS CNB and have hemispheric lateralization (right) of deficits. Our findings challenge the loss of asymmetry verdicts in schizophrenia.

The normal function of the medial prefrontal cortex (mPFC) is essential for regulating neurocognition, but it is disrupted in the early stages of Alzheimer’s disease (AD) before the accumulation of Aβ and the appearance of symptoms. Despite this, little is known about how the functional activity of medial prefrontal cortex pyramidal neurons changes as Alzheimer’s disease progresses during aging. We used electrophysiological techniques (patch-clamping) to assess the functional activity of medial prefrontal cortex pyramidal neurons in the brain of 3xTg-Alzheimer’s disease mice modeling early-stage Alzheimer’s disease without Aβ accumulation. Our results indicate that firing rate and the frequency of spontaneous excitatory postsynaptic currents (sEPSCs) were significantly increased in medial prefrontal cortex neurons from young Alzheimer’s disease mice (4–5-month, equivalent of <30-year-old humans) compared to agematched control mice. Blocking ionotropic glutamatergic NMDA receptors, which regulate neuronal excitability and Ca2+ homeostasis, abolished this neuronal hyperactivity. There were no changes in Ca2+ influx through the voltage-gated Ca2+ channels (VGCCs) or inhibitory postsynaptic activity in medial prefrontal cortex neurons from young Alzheimer’s disease mice compared to controls. Additionally, acute exposure to Aβ42 potentiated medial prefrontal cortex neuronal hyperactivity in young Alzheimer’s disease mice but had no effects on controls. These findings indicate that the hyperactivity of medial prefrontal cortex pyramidal neurons at early-stage Alzheimer’s disease is induced by an abnormal increase in presynaptic glutamate release and postsynaptic NMDA receptor activity, which initiates neuronal Ca2+ dyshomeostasis. Additionally, because accumulated Aβ forms unconventional but functional Ca2+ channels in medial prefrontal cortex neurons in the late stage of Alzheimer’s disease, our study also suggests an exacerbated Ca2+ dyshomeostasis in medial prefrontal cortex pyramidal neurons following overactivation of such VGCCs.

Background: Individuals with autism spectrum disorder (ASD) are challenged not only by the defining features of social-communication deficits and restricted repetitive behaviors, but also by a myriad of psychopathology varying in severity. Different cognitive deficits underpin these psychopathologies, which could be subjected to intervention to alter the course of the disorder. Understanding domain-specific mediating effects of cognition is essential for developing targeted intervention strategies. However, the high degree of inter-correlation among different cognitive functions hinders elucidation of individual effects. Methods: In the Philadelphia Neurodevelopmental Cohort, 218 individuals with ASD were matched with 872 non-ASD controls on sex, age, race, and socioeconomic status. Participants of this cohort were deeply and broadly phenotyped on neurocognitive abilities and dimensional psychopathology. Using structural equation modeling, inter-correlation among cognitive domains were adjusted before mediation analysis on outcomes of multi-domain psychopathology and functional level. Results: While social cognition, complex cognition, and memory each had a unique pattern of mediating effect on psychopathology domains in ASD, none had significant effects on the functional level. In contrast, executive function was the only cognitive domain that exerted a generalized negative impact on every psychopathology domain (p factor, anxious-misery, psychosis, fear, and externalizing), as well as functional level. Conclusions: Executive function has a unique association with the severity of comorbid psychopathology in ASD, and could be a target of interventions. As executive dysfunction occurs variably in ASD, our result also supports the clinical utility of assessing executive function for prognostic purposes. [ABSTRACT FROM AUTHOR]

The study of Obsessive-Compulsive Disorder (OCD) genomics has primarily been tackled by Genome-wide association studies (GWAS), which have encountered troubles in identifying replicable single nucleotide polymorphisms (SNPs). Endophenotypes have emerged as a promising avenue of study in trying to elucidate the genomic bases of complex traits such as OCD. We analyzed the association of SNPs across the whole genome with the construction of visuospatial information and executive performance through four neurocognitive variables assessed by the Rey-Osterrieth Complex Figure Test (ROCFT) in a sample of 133 OCD probands. Analyses were performed at SNP- and gene-level. No SNP reached genome-wide significance, although there was one SNP almost reaching significant association with copy organization (rs60360940; P = 9.98E-08). Suggestive signals were found for the four variables at both SNP- (P < 1E-05) and gene-levels (P < 1E-04). Most of the suggestive signals pointed to genes and genomic regions previously associated with neurological function and neuropsychological traits. Our main limitations were the sample size, which was limited to identify associated signals at a genome-wide level, and the composition of the sample, more representative of rather severe OCD cases than a population-based OCD sample with a broad severity spectrum. Our results suggest that studying neurocognitive variables in GWAS would be more informative on the genetic basis of OCD than the classical case/control GWAS, facilitating the genetic characterization of OCD and its different clinical profiles, the development of individualized treatment approaches, and the improvement of prognosis and treatment response. • Suggestive signals were found for visuospatial processing and recall. • The top signals pointed to the involvement of genes with a neurological role. • OCD GWAS on cognitive traits rather than case/control status might be more informative.

Introduction: COVID-19 induces both acute and chronic neurological changes. Existing evidence suggests that chemosensory changes, particularly olfactory loss, may reflect central neurological dysfunction in neurodegenerative diseases and mark progression from mild cognitive impairment to Alzheimer’s. This scoping review summarizes the available literature to evaluate the relationship between neurocognition and olfaction in young to middle-aged adults with minimal comorbidities following COVID-19 infection. Methods: A literature search of PubMed, Ovid Embase, Web of Science, and Cochrane Library was conducted. Studies underwent title/abstract and full text screening by two reviewers, with a third reviewer resolving any conflicts. Remaining studies underwent data extraction. Results: Seventeen studies were eligible for data extraction after the review process, where 12 studies found significantly poorer cognition in those suffering from olfactory dysfunction, four studies showed no association between cognition and olfaction, and one study reported lower anosmia prevalence among patients with cognitive impairment. Conclusion: The majority of studies in this review find that olfactory dysfunction is associated with poorer cognition. More rigorous studies are needed to further elucidate the relationship between olfaction and cognition after COVID-19. [ABSTRACT FROM AUTHOR]

Impairment in attention, memory, processing speed and executive functions have been described in patients with schizophrenia. Such impairments can be observed in early stages of the disease and in chronic patients; discrepancy in findings regarding the cognitive deficits at different stages of the illness keeps the debate about schizophrenia as a neurodegenerative condition which courses with continuous deterioration, or if deficits remain stable, as the neurodevelopmental hypothesis suggests. The aim of the present study was to compare the cognitive performance of recent-onset (RO) and chronic (CH) schizophrenia patients to contrast the neurodevelopmental hypothesis against the neurodegenerative approach. Methods. Twenty RO participants (< 5 years from first psychotic episode) and 30 CH patients (> 5 years from first psychotic episode) were included in the sample. The MATRICS Consensus Cognitive Battery (MCCB), Tower of London test (ToL), Wisconsin Card Sorting Test (WCST) and Stroop Test were used for cognitive evaluation. ANCOVA analysis was performed for group comparisons. Results. No differences between RO and CH patients were identified on most cognitive tests. However, a significant difference was observed in the visual spatial span test from MCCB. Conclusions. We conclude that cognitive deficits remain stable over the course of the disease. Our findings are consistent with the neurodevelopmental hypothesis of schizophrenia rather than the neurodegenerative approach. [ABSTRACT FROM AUTHOR]

Purpose: Craniosynostosis, which describes premature fusion of one or more cranial sutures, has been associated with a variety of neurocognitive deficits. We sought to explore the cognitive profiles of the various types of single-suture, non-syndromic craniosynostosis (NSC). Methods: A retrospective review of children 6-18 years old with surgically corrected NSC who underwent neurocognitive testing (Weschler Abbreviated Scale of Intelligence, Beery-Buktenica Developmental Test of Visuomotor Integration) from the years 2014-2022 was conducted. Results: 204 patients completed neurocognitive testing (139 sagittal, 39 metopic, 22 unicoronal, 4 lambdoid suture). 110 (54%) of the cohort was male, and 150 (74%) were White. Mean IQ was 106.10±14.01 and mean age at surgery and testing were 9.0±12.2 months and 10.9±4.0 years, respectively. Sagittal synostosis was associated with higher scores than metopic synostosis, with significant differences in verbal IQ (109.42±15.76 vs 101.37±10.41), full-scale IQ (108.32±14.44 vs 100.05±11.76), visuomotor integration (101.62±13.64 vs 92.44±12.07), visual perception (103.81±12.42 vs 95.87±11.23), and motor coordination (90.45±15.60 vs 84.21±15.44). Sagittal synostosis was associated with significantly higher scores for visuomotor integration (101.62±13.64 vs 94.95±10.24) and visual perception (103.81±12.42 vs 94.82±12.75) than unicoronal synostosis. Conclusions: Compared to patients with sagittal synostosis, patients with metopic synostosis exhibited lower scores in verbal IQ, full-scale IQ, visuomotor integration, visual perception, and motor control after surgical correction. Despite surgical correction for premature metopic suture fusion, the effect on the adjacent frontal lobe and white matter connections to other regions of the brain may have a lasting functional impact. Patients with unicoronal synostosis exhibited lower visuomotor integration and visual perception scores. [ABSTRACT FROM AUTHOR]

Studies across schizophrenia (SZ) and bipolar disorder (BD) indicate common transdiagnostic neurocognitive subgroups. However, existing studies of patients with long-term illness precludes insight into whether impairments result from effects of chronic illness, medication or other factors. This study aimed to investigate whether neurocognitive subgroups across SZ and BD can be demonstrated during early illness stages. Data from overlapping neuropsychological tests were pooled from cohort studies of antipsychotic-naïve patients with first-episode SZ spectrum disorders (n = 150), recently diagnosed BD (n = 189) or healthy controls (HC) (n = 280). Hierarchical cluster analysis was conducted to examine if transdiagnostic subgroups could be identified based on the neurocognitive profile. Patterns of cognitive impairments and patient characteristics across subgroups were examined. Patients could be clustered into two, three and four subgroups, of which the three-cluster solution (with 83% accuracy) was selected for posthoc analyses. This solution revealed a subgroup covering 39% of patients (predominantly BD) who were cognitively relatively intact , a subgroup of 33% of patients (more equal distributions of SZ and BD) displaying selective deficits, particularly in working memory and processing speed, and a subgroup of 28% (mainly SZ) with global impairments. The globally impaired group exhibited lower estimated premorbid intelligence than the other subgroups. Globally impaired BD patients also showed more functional disability than cognitively relatively intact patients. No differences were observed across subgroups in symptoms or medications. Neurocognitive results can be understood by clustering analysis with similar clustering solutions occurring across diagnoses. The subgroups were not explained by clinical symptoms or medication, suggesting neurodevelopmental origins. • Across schizophrenia and bipolar disorder, patients could be clustered according to their neurocognitive profile already at early illness stages. • We identified 2-, 3- and 4-cluster solutions, of which the 3-cluster solution was deemed optimal given its high accuracy and detailed information. • In the 3-cluster solution, patients were divided into a relatively intact (39%), selectively impaired (33%), or globally impaired (28%) subgroup. • 'Globally impaired' subgroup (mainly SZ) presented with more functional impairments and lower premorbid intelligence.

Depressive symptom and psychotic symptom have been identified as risk factors for impaired socio-occupational functioning in patients with major depressive disorder (MDD), while neurocognitive functioning is considered to be a potential protective factor against socio-occupational functioning. Nevertheless, little is known about the complex relationship among these factors in patients with MDD. The purpose of this research was to explore whether the relationship between depressive symptom severity and social-occupational functioning is mediated by neurocognitive functioning and psychotic symptom severity in MDD patients. A total of 659 eligible MDD patients included male and female, and their depressive symptoms and psychotic symptoms at baseline were assessed by the 17-item Hamilton Depression Scale (HAMD-17) and The Brief Psychiatric Rating Scale (BPRS) respectively. Cognitive domains were assessed by the MATRICS Consensus Cognitive Battery (MCCB), and subjective and objective functioning were measured by the Global Assessment of Functioning (GAF). The analysis is cross-sectional, which limits causal inference. (1) The correlation between depressive symptoms and thought disturbance was positive (r = 0.125, p = 0.001), whereas the correlations with visual learning and memory (r = −0.146, p < 0.001) and socio-occupational functioning (r = −0.175, p < 0.001) were negative. (2) Depressive symptoms mainly affect the socio-occupational functioning of MDD patients via three indirect effects: the single mediating effect of psychotic symptoms and neurocognitive functioning, and the chain mediating effect of psychotic symptoms and neurocognitive functioning. The results suggest that the relationship between depressive symptom severity and socio-occupational functioning in MDD patients is partially mediated by psychotic symptom severity and neurocognitive functioning. • Focusing on depressive symptoms and socio-occupational functioning among patients • The relationship is mediated by neurocognition and psychotic symptom severity. • First study to explore the chained mediation model of the study variables [ABSTRACT FROM AUTHOR]

Schizophrenia spectrum disorders (SSD) often show cognitive deficits (CD) impacting daily life. Family support has been shown to be protective against CD, yet the relationship between these in psychotic patients remains complex and not fully understood. This study investigated the association between a subdomain of family support, namely, family involvement (estimated through a proxy measure), cognitive functioning, and sex in first-episode psychosis (FEP) patients. The sample included 308 patients enrolled in the Program for Early Phases of Psychosis (PAFIP), divided into 4 groups based on their estimated family involvement (eFI) level and sex, and compared on various variables. Women presented lower rates of eFI than men (37.1% and 48.8%). Higher eFI was associated with better cognitive functioning, particularly in verbal memory. This association was stronger in women. The findings suggest that eFI may be an important factor in FEP patients' cognitive functioning. This highlights the importance of including families in treatment plans for psychotic patients to prevent CD. Further research is needed to better understand the complex interplay between family support, sex, and cognitive functioning in psychotic patients and develop effective interventions that target these factors.

As cognitive function is critical for muscle coordination, cognitive training may also improve neuromuscular control strategy and knee function following an anterior cruciate ligament reconstruction (ACLR). The purpose of this case-control study was to examine the effects of cognitive training on joint stiffness regulation in response to negative visual stimuli and knee function following ACLR. A total of 20 ACLR patients and 20 healthy controls received four weeks of online cognitive training. Executive function, joint stiffness in response to emotionally evocative visual stimuli (neutral, fearful, knee injury related), and knee function outcomes before and after the intervention were compared. Both groups improved executive function following the intervention (p = 0.005). The ACLR group had greater mid-range stiffness in response to fearful (p = 0.024) and injury-related pictures (p = 0.017) than neutral contents before the intervention, while no post-intervention stiffness differences were observed among picture types. The ACLR group showed better single-legged hop for distance after cognitive training (p = 0.047), while the healthy group demonstrated no improvement. Cognitive training enhanced executive function, which may reduce joint stiffness dysregulation in response to emotionally arousing images and improve knee function in ACLR patients, presumably by facilitating neural processing necessary for neuromuscular control.

Mucolipidosis type II (MLII), an ultra-rare lysosomal storage disorder, manifests as a fatal multi-systemic disease. Mental inhibition and progressive neurodegeneration are commonly reported disease manifestations. Nevertheless, longitudinal data on neurocognitive testing and neuroimaging lack in current literature. This study aimed to provide details on central nervous system manifestations in MLII. All MLII patients with at least one standardized developmental assessment performed between 2005 and 2022 were included by retrospective chart review. A multiple mixed linear regression model was applied. Eleven patients with a median age of 34.0 months (range 1.6–159.6) underwent 32 neurocognitive and 28 adaptive behaviour assessments as well as 14 brain magnetic resonance imagings. The scales used were mainly BSID-III (42%) and VABS-II (47%). Neurocognitive testing (per patient: mean 2.9, standard deviation (SD) 2.0) performed over 0–52.1 months (median 12.1) revealed profound impairment with a mean developmental quotient of 36.7% (SD 20.4) at last assessment. The patients showed sustained development; on average, they gained 0.28 age-equivalent score points per month (confidence interval 0.17–0.38). Apart from common (63%) cervical spinal stenosis, neuroimaging revealed unspecific, non-progressive abnormalities (i.e., mild brain atrophy, white matter lesions). In summary, MLII is associated with profound developmental impairment, but not with neurodegeneration and neurocognitive decline. [ABSTRACT FROM AUTHOR]

Suicide and homicide are considered important problems in public health. This study aims to identify the cognitive performance of suicidal and homicidal behaviors in people with schizophrenia spectrum disorders, as well as examining whether there are shared neuropsychological mechanisms. A systematic review of the recent literature was carried out from September 2012 to June 2022 using the Medline (via PubMed), Scopus, Embase, and Cochrane databases. Among the 870 studies initially identified, 23 were finally selected (15 related to suicidal behaviors and 8 to homicidal behaviors). The results evidenced a relationship between impairment of cognitive performance and homicidal behavior; meanwhile, for suicidal behaviors, no consistent results were found. High neuropsychological performance seems to act as a protective factor against violent behavior in people with schizophrenia spectrum disorders, but not against suicidal behavior; indeed, it can even act as a risk factor for suicidal behavior. To date, there is insufficient evidence that shared neurocognitive mechanisms exist. However, processing speed and visual memory seem to be affected in the presence of both behaviors.

Children and young adults with congenital central hypoventilation syndrome (CCHS) are at risk of cognitive deficits. They experience autonomic dysfunction and chemoreceptor insensitivity measured during ventilatory and orthostatic challenges, but relationships between these features are undefined. Can a biomarker be identified from physiologic responses to ventilatory and orthostatic challenges that is related to neurocognitive outcomes in CCHS? This retrospective study included 25 children and young adults with CCHS tested over an inpatient stay. Relationships between physiologic measurements during hypercarbic and hypoxic ventilatory challenges, hypoxic ventilatory challenges, and orthostatic challenges and neurocognitive outcomes (by Wechsler intelligence indexes) were examined. Independent variable inclusion was determined by significant associations in Pearson's analyses. Multivariate linear regressions were used to assess relationships between measured physiologic responses to challenges and neurocognitive scores. Significant relationships were identified between areas of fluid intelligence and measures of oxygen saturation (SpO 2) and heart rate (HR) during challenges. Specifically, perceptual reasoning was related to HR (adjusted regression [β] coefficient, –0.68; 95% CI, 1.24 to –0.12; P =.02) during orthostasis. Working memory was related to change in HR (β, –1.33; 95% CI, –2.61 to –0.05; P =.042) during the hypoxic ventilatory challenge. Processing speed was related to HR (β, –1.19; 95% CI, –1.93 to –0.46; P =.003) during orthostasis, to baseline SpO 2 (hypercarbic and hypoxic β, 8.57 [95% CI, 1.63-15.51]; hypoxic β, 8.37 [95% CI, 3.65-13.11]; P =.002 for both) during the ventilatory challenges, and to intrachallenge SpO 2 (β, 5.89; 95% CI, 0.71-11.07; P =.028) during the hypoxic ventilatory challenge. In children and young adults with CCHS, SpO 2 and HR—or change in HR—at rest and as a response to hypoxia and orthostasis are related to cognitive outcomes in domains of known risk, particularly fluid reasoning. These findings can guide additional research on the usefulness of these as biomarkers in understanding the impact of daily physical stressors on neurodevelopment in this high-risk group.

Background: Sex differences in brain structure and neurodevelopment occur in non-clinical populations. We investigated whether sex had a similar effect on developmental domains amongst boys and girls with a familial risk of schizophrenia (FHR-SZ), bipolar disorder (FHR-BP), and controls. Methods: Through Danish registries, we identified 522 7-year-old children (242 girls) with FHR-SZ, FHR-BP, and controls. We assessed their performance within the domains of neurocognition, motor function, language, social cognition, social behavior, psychopathology, and home environment. Results: FHR-SZ boys compared with FHR-SZ girls had a higher proportion of disruptive behavior and attention-deficit hyperactivity disorder (ADHD) and exhibited lower performance in manual dexterity, balance, and emotion recognition. No sex differences were found between boys and girls within FHR-BP group. Compared with controls, both FHR-SZ boys and FHR-SZ girls showed impaired processing speed and working memory, had lower levels of global functioning, and were more likely to live in an inadequate home environment. Compared with control boys, FHR-SZ boys showed impaired manual dexterity, social behavior, and social responsiveness, and had a higher proportion of ADHD and disruptive behavior disorder diagnoses. Stress and adjustment disorders were more common in FHR-BP boys compared with control boys. We found no differences between FHR-BP girls and control girls. Conclusions: Impairment within neurodevelopmental domains associated within FHR-SZ boys v. FHR-SZ girls was most evident among boys, whereas no sex differences were found within the FHR-BP group (FHR-BP boys v. FHR-BP girls). FHR-SZ boys exhibited the highest proportion of early developmental impairments. [ABSTRACT FROM AUTHOR]

Background: Grey matter (GM) reduction is a consistent observation in established late stages of schizophrenia, but patients in the untreated early stages of illness display an increase as well as a decrease in GM distribution relative to healthy controls (HC). The relative excess of GM may indicate putative compensatory responses, though to date its relevance is unclear. Methods: 343 first-episode treatment-naïve patients with schizophrenia (FES) and 342 HC were recruited. Multivariate source-based morphometry was performed to identify covarying 'networks' of grey matter concentration (GMC). Neurocognitive scores using the Cambridge Neuropsychological Test Automated Battery (CANTAB) and symptom burden using the Positive and Negative Symptoms Scale (PANSS) were obtained. Bivariate linear relationships between GMC and cognition/symptoms were studied. Results: Compared to healthy subjects, FES had prominently lower GMC in two components; the first consists of the anterior insula, inferior frontal gyrus, anterior cingulate and the second component with the superior temporal gyrus, precuneus, inferior/superior parietal lobule, cuneus, and lingual gyrus. Higher GMC was seen in adjacent areas of the middle and superior temporal gyrus, middle frontal gyrus, inferior parietal cortex and putamen. Greater GMC of this component was associated with lower duration of untreated psychosis, less severe positive symptoms and better performance on cognitive tests. Conclusions: In untreated stages of schizophrenia, both a distributed lower and higher GMC is observable. While the higher GMC is relatively modest, it occurs across frontoparietal, temporal and subcortical regions in association with reduced illness burden suggesting a compensatory role for higher GMC in the early stages of schizophrenia.

Background: The relationship between major depressive disorder (MDD) and personality disorders is complex, with implications for diagnosis and treatment. We sought to explore the relationship between these disorders quantitatively in an inpatient setting. Methods: We conducted a structured observational study exploring symptoms of depression and selected neurocognitive functions over the span of an inpatient admission in those with depression and personality disorders. Sixty inpatients presenting with symptoms of depression completed ratings of mood and neurocognitive function. Diagnosis was confirmed by structured clinical interview (SCID-5-RV) at discharge and used to allocate patients to one of the two groups for analysis: those with MDD-only and those with a personality disorder (with or without MDD). Results: On admission, observer-based ratings of depression were significantly higher in the MDD-only group while subjective ratings were higher in the personality disorder group. Depression rating scores lessened in both groups during the admission, but at discharge, the personality disorder group continued to report higher subjective ratings. The personality disorder group also rated themselves as more cognitively impaired than the MDD-only group and unlike the MDD-only group, they did not report subjective improvements in cognitive function over the course of admission. Objective assessment of cognitive function demonstrated improvements in both groups. Conclusions: In this study, the presence of a personality disorder was associated with greater subjective severity of depressive symptomatology and selected neurocognitive functioning, despite similar or lower objective severity in comparison with those with MDD. This finding has implications for understanding the patient journey through health care settings. [ABSTRACT FROM AUTHOR]

Many illness-related factors contribute to the reduction of the real-life functioning observed in people with schizophrenia (SZ). These include the psychopathological dimensions of the disorder such as positive, negative, disorganization, and depressive symptoms as well as impairment in neurocognition, social cognition, and metacognition. The associations between some of these variables change with the duration of illness (DOI), but this aspect was not explored with a network approach. This study aimed at describing and comparing the inter-relationships between psychopathological, cognitive, and functioning variables in early (DOI ≤ 5 years) and late (DOI > 5 years) phase SZ with network analyses and at assessing which variables were more strictly and directly associated with the real-life functioning. A network representation of the relationships between variables and the calculation of centrality indices were performed within each group. The two groups were compared with a network comparison test. Seventy-five patients with early and ninety-two with late phase SZ were included. No differences in the global network structure and strength were found between the two groups. In both groups, visual learning and disorganization exhibited high centrality indices and disorganization, negative symptoms, and metacognition were directly and strongly associated with real-life functioning. In conclusion, regardless of the DOI, a rehabilitation aimed at improving visual learning and disorganization (i.e., the most central variables) might reduce the strength of the associations that compose the network and therefore indirectly facilitate functional recovery. Simultaneously, therapeutic interventions targeting disorganization and metacognition might directly improve real-life functioning. [ABSTRACT FROM AUTHOR]

Non-suicidal self-injury (NSSI) is becoming increasingly common in adolescents and seriously affects their physical and mental health, and it is also a major risk factor for suicide among adolescents. NSSI has now become a public health issue of general concern; however, the identification of cognitive dysfunction in NSSI is still based on neuropsychological cognitive assessment and subjective questionnaire assessment, with a lack of objective evaluation indicators. As a method for studying the cognitive neural mechanism of NSSI, electroencephalography is a reliable tool for finding objective biomarkers of NSSI. This article reviews the recent research on electrophysiology associated with cognitive dysfunction in adolescents with NSSI. [ABSTRACT FROM AUTHOR]

Introduction: Survival of children and adolescents diagnosed with central nervous system (CNS) tumors massively improved over the last decades due to better diagnostics, treatment, and supportive care. However, morbidity is still the highest of all cancer entities in this age group with neurocognitive late-effects being one of the most severe. Aim: With this systematic review, we aim to summarize interventions designed to prevent or improve neurocognitive late-effects in CNS tumor patients. Method: We searched PubMed on August 16th 2022 and included publications studying interventions for neurocognitive late-effects in pediatric and adolescent patients and survivors diagnosed with a CNS tumor. We included any form of neurocognitive intervention during treatment or following treatment completion. We considered all types of studies except for expert opinions and case reports. Results: The literature search resulted in 735 publications. We included 43 publications in the full text screening and 14 met our inclusion criteria. Of those, two assessed the impact of pharmacological interventions, three of exercise interventions, five of online cognitive training, and four assessed behavioral interventions. Different neuropsychological test batteries and imaging were used to measure the impact of the respective interventions. Most studies showed a positive impact of the interventions in single to several of the subtests used. Conclusion: We found several intervention studies indicating improvement of neurocognitive problems in children and adolescent CNS tumor survivors. In this population exercise interventions or online cognitive training might mitigate or improve neurocognitive late-effects. [ABSTRACT FROM AUTHOR]

Black Americans are diagnosed with schizophrenia spectrum disorders at more than twice the rate of White individuals and experience significantly worse outcomes following diagnosis. Little research has examined specific factors that may contribute to worse functional outcomes among Black Americans diagnosed with schizophrenia. One approach to understanding why racial disparities emerge is to examine established predictors of functioning in this population: neurocognition, social cognition, and symptom severity. The present study aims to broaden existing literature on racial differences within these domains by (a) examining racial differences in functioning and these established predictors of functioning (i.e., neurocognition, social, and symptom severity) and (b) investigating whether cognition and symptom domains similarly predict functioning between Black and White Americans with schizophrenia. Sixty-six participants' baseline neurocognition, social cognition, symptom severity, and functioning were assessed. Black participants demonstrated lower neurocognition scores and higher levels of disorganized symptoms relative to White participants. No racial differences in functioning or social cognition were observed. Further, race did not moderate the relationship between any of these established predictors and functioning outcomes. The largely nonsignificant differences in known predictors of functioning highlight the need to explore further domains that may be more relevant for understanding racial disparities in schizophrenia. Considering that psychosocial treatments for schizophrenia spectrum disorders often focus on cognition, these results underscore the importance of identifying whether these domains or other treatment targets may be better in addressing racial disparities in functioning. Possible areas of exploration for future work (e.g., structural factors, racism-related stress) are discussed. Public Policy Relevance Statement: Black individuals are at greater risk for experiencing poorer functional outcomes once diagnosed with schizophrenia relative to White individuals. The findings of this study indicate a need to critically examine established predictors of functioning in schizophrenia (i.e., symptoms, social cognition, and neurocognition) to better understand racial disparities in schizophrenia. This will importantly influence policy and treatment reform to better serve Black individuals suffering from schizophrenia spectrum disorders. [ABSTRACT FROM AUTHOR]

Human rationality has a dual nature including analytic and common-sense thinking. Symptoms of schizophrenia have been suggested to be related to deficits in these aspects of logical reasoning. However, empirical studies investigating logical reasoning errors in schizophrenia and their clinical and neurocognitive correlates are scarce. Formal thought disorder and theory of mind (ToM) might be particularly important for understanding logical reasoning errors in schizophrenia. The current study compared the performances of 80 patients with schizophrenia with those of 49 healthy controls on syllogistic and counterfactual reasoning tasks and investigated clinical, neuropsychological, and social cognitive correlates of logical reasoning in schizophrenia. Patients with schizophrenia were impaired in both analytic and common-sense thinking. ToM impairment was a significant predictor of analytic reasoning abilities in schizophrenia. Executive functions and verbal memory were also significantly associated with analytic reasoning in schizophrenia. Further studies investigating logical reasoning errors in the early phases of the illness are needed. [ABSTRACT FROM AUTHOR]

The effect of multiple general anesthesia (mGA) procedures administered in early life is a critical theme and has led the Food and Drug Administration (FDA) to issue an alert. This systematic review seeks to explore the potential effects on neurodevelopment of mGA on patients under 4 years. The Medline, Embase and Web of Science databases were searched for publications up to 31 March 2021. The databases were searched for publications regarding "children multiple general anesthesia OR pediatric multiple general anesthesia". Case reports, animal studies and expert opinions were excluded. Systematic reviews were not included, but they were screened to identify any possible additional information. A total of 3156 studies were identified. After removing the duplicates, screening the remaining records and analyzing the systematic reviews' bibliography, 10 studies were considered suitable for inclusion. Comprehensively, a total cohort of 264.759 unexposed children and 11.027 exposed children were assessed for neurodevelopmental outcomes. Only one paper did not find any statistically significant difference between exposed and unexposed children in terms of neurodevelopmental alterations. Controlled studies on mGA administered before 4 years of age support that there might be a greater risk of neurodevelopmental delay in children receiving mGA, warranting the need for careful risk/benefit considerations.

Background: Alcohol intoxication disrupts many aspects of cognition, including the generation of phenomenological characteristics of future events (a component of episodic foresight), and the execution of directed preparatory behaviours (a component of prospective memory). However, no study has tested whether alcohol intoxication is also associated with deficits engaging episodic foresight to guide future-directed behaviour. Aims: This study was designed to provide the first test of how alcohol intoxication influences the functional application of episodic foresight. The secondary aim was to establish the degree to which any observed episodic foresight difficulties associated with alcohol use might reflect broader problems in retrospective memory and executive control. Sex differences were also examined. Methods: Healthy adult social drinkers randomly received either a moderate dose of 0.6 g/kg alcohol (n = 61) or a matched placebo drink (n = 63) and then completed a validated measure that met strict criteria for assessing the functional application of episodic foresight as well as a broader cognitive test battery. Results: Relative to the placebo condition, episodic foresight was impaired by acute alcohol consumption, with this impairment related to poorer retrospective memory, but not executive control. The negative effects of alcohol intoxication on episodic foresight did not differ as a function of sex. Conclusions: Even a moderate level of intoxication impairs the ability to use episodic foresight in a functionally adaptive way. These findings have implications for understanding many of the maladaptive behaviours that are often associated with acute alcohol use. [ABSTRACT FROM AUTHOR]

Children with childhood cancer are at high risk of a wide range of cognitive difficulties. Therefore, interventions directed to these difficulties are necessary. Anticancer treatments such as chemotherapy and/or radiotherapy are at high risk of late effects of neurocognitive deficits. The present study presents the case of an 8-year-old female child, attending elementary school, diagnosed with acute lymphoblastic leukemia -ALL at 8 years of age, undergoing chemotherapy during the COVID-19 pandemic. Pragmatic language, verbal and visual episodic memory, executive functions, concentrated attention, writing ability, and behavior were evaluated. The results of the neuropsychological evaluation suggested deficits in the tasks of executive functions of lexical access (free fluency, phonemic and semantic), with significant impairments also in cognitive flexibility, working memory, and concentrated attention. The deficits presented are well linked to the existing literature on the neuropsychological outcome of children with ALL during childhood. However, these findings may also be linked to the pandemic's consequences on children's cognition.This study sought to contribute to the Brazilian and international knowledge that is still lacking in reports of neuropsychological outcomes of children with ALL undergoing treatment, and after the pandemic, who receive pedagogical assistance at hospitals provided by the public education and health network in a hospital environment by the public school and health network. In order to elucidate the national importance of this clinically delicate Clinical group having access to neuropsychological examination, in order to trace possible deficits and potentialities.

Little is known about the long-term effects of maternal diabetes during pregnancy (DP), either gestational diabetes or preexisting diabetes (type 1 or type 2), on offspring's brain morphometry and neurocognitive functioning (NCF). This study examined the effect of prenatal exposure to maternal DP on the brain structure and NCF in children between 9 and 10 years of age. This study used cross-sectional neuroimaging and NCF data from the baseline wave of the Adolescent Brain and Cognitive Development® study. Exposure to maternal DP was assigned from the developmental history questionnaire. Differences in the brain cortical thickness (CTh) and five cognitive abilities (executive function, working and episodic memory, processing speed, and language abilities) were examined in diabetes-exposed and diabetes-unexposed children. Linear mixed effect models and generalized linear models were used to adjust for the effect of confounding variables. A total of 9,967 children (718 diabetes-exposed and 9249 unexposed) were included in the analysis. Diabetes-exposed children had lower whole-brain CTh [mean: exposed vs unexposed = 2.725 mm vs 2.732 mm; difference (95%CI): −0.007 mm (−0.013, −0.001)] compared to unexposed children after adjusting for confounding variables. Diabetes-exposed children had lower CTh in most part of the occipital lobe of both hemispheres, right postcentral gyrus, and left superior parietal cortex. Diabetes-exposed children also had lower scores in processing speed task [mean difference (95%CI): −1.7 (−2.8, −0.6)] and total cognition [mean difference (95%CI): −0.6 (−1.2, −0.02)]. Diabetes-exposed children have reduced CTh and NCF during preadolescence, which might have implications for psychomotor development during later life. Prospective studies are needed to confirm our findings. [ABSTRACT FROM AUTHOR]

Perceived threat in youth's environments can elevate risk for mental health, social, and neurocognitive difficulties throughout the lifespan. However, few studies examine variability in youth's perceptions of threat across multiple contexts or evaluate outcomes across multiple domains, ultimately limiting our understanding of specific risks associated with perceived threats in different contexts. This study examined associations between perceived threat in youth's neighborhood, school, and family contexts at ages 9–10 and mental health, social, and neurocognitive outcomes at ages 11–12 within a large US cohort (N = 5525) enrolled in the Adolescent Brain Cognitive DevelopmentSM Study (ABCD Study®). Latent profile analysis revealed four distinct profiles: Low Threat in all contexts, Elevated Family Threat, Elevated Neighborhood Threat, and Elevated Threat in all contexts. Mixed-effect models and post hoc pairwise comparisons showed that youth in Elevated Threat profile had poorer mental health and social outcomes 2 years later. Youth in the Elevated Family Threat profile uniquely showed increased disruptive behavior symptoms, whereas youth in the Elevated Neighborhood Threat profile predominantly displayed increased sleep problems and worse neurocognitive outcomes 2 years later. Together, findings highlight the importance of considering perceptions of threat across multiple contexts to achieve a more nuanced developmental picture. [ABSTRACT FROM AUTHOR]

Individuals with schizophrenia spectrum disorders (SSD) have significantly lower life-expectancy than healthy people. Previously, we have identified baseline neurocognitive function in general and verbal memory and executive function in particular as related to mortality nearly two decades later. In this study, we aim to replicate these findings with a larger and age-matched sample. The patient group consisted of 252 individuals, 44 of whom were deceased and 206 alive. Neurocognition was assessed with a comprehensive battery. Results showed that the deceased group, compared to the living group, had significantly more severe neurocognitive deficits across nearly all domains. There were no differences in sex, remission status, psychosis symptoms, or function level between the groups. Immediate verbal memory and executive function were the strongest predictors of survival status. These results were nearly identical to our previous studies, and we conclude that baseline neurocognitive function is an important predictor for mortality in SSD. Clinicians should be mindful of this relationship in patients with significant cognitive deficits.

Objective: Cognitive impairment is an essential feature of schizophrenia, and it involves a broad array of nonsocial and social cognitive domains. This study aimed to examine whether there are the same or different social cognition profiles between two cognitive subtypes of schizophrenia. Method: There were one hundred and two chronic and institutionalized patients with schizophrenia from two referral tracks. One group is “Cognitively Normal Range” (CNR) (N = 52), and another group is “Below Normal Range” (BNR) (N = 50). We assessed or collected their apathy, emotional perception judgment, facial expression judgment, and empathy by the Apathy Evaluation Scale, the International Affective Picture System, the Japanese and Caucasian Facial Expression of Emotion, and the Interpersonal Reactivity Index, respectively. Results: We found different impairment profiles depending on the cognitive subtypes of the patient with schizophrenia. Surprisingly, the CNR presented impairments in apathy, emotional perception judgment, facial expression judgment, and empathy and feature impairment in empathy and affective apathy. In contrast, even though the BNR had significant neurocognition impairments, they had almost intact empathy with significantly impaired cognitive apathy. Both groups' global deficit scores (GDSs) were comparable, and all reached at least a mild impairment level. Conclusions: The CNR and the BNR had similar abilities in emotional perception judgment and facial emotion recognition. They also had differentiable deficits in apathy and empathy. Our findings provide important clinical implications for neuropsychological pathology and treatment in schizophrenia.

The radical imagination entails stepping outside the confines of the now and into the expansiveness of what could be. It has been described as the ability to dream of possible futures and bring these possibilities back to the present to drive social transformation. This perspective paper seeks to provide an overview of the radical imagination and its intersections with Afrofuturism, a framework and artistic epistemology that expresses the Black cultural experience through a space of hope where Blackness is integral. In this paper, I propose three processes that comprise the radical imagination: (1) imagining alternative Black futures, (2) radical hope, and (3) collective courage. I consider the neural networks that underlie each process and consider how the Black radical imagination is a portal through which aging Black adults experience hope and envision futures that drive social change. I conclude with considerations of what brain health and healing justice looks like for aging Black Americans— specifically, how invocation of the Black radical imagination may have positive brain health effects for a demographic group at increased risk for Alzheimer’s disease and related dementias.

Homelessness is a major public health problem, and serious mental illness (SMI) is highly prevalent in the homeless population. Although supported housing services-which provide permanent housing in the community along with case management-improve housing outcomes, community integration typically remains poor, and little is known about the underlying determinants of poor community integration postresidential placement. The general SMI literature has indicated that motivational and cognitive ability factors are key determinants of successful community integration, which provides a foundation for examining this issue. This study evaluated whether interview- and performance-based assessments of motivation, nonsocial and social-cognitive ability, and psychiatric symptoms were associated with community integration indices in 2 samples of homeless veterans either with (N = 96) or without (N = 80) a psychotic disorder who had recently been admitted to a supported housing program but who had not yet attained housing. Motivation indices, including experiential negative symptoms and defeatist performance attitudes, stood out as the most robust correlates (rs = -.30 to -.69) of community integration across both samples, particularly for social role participation. Demographics, general psychiatric symptoms, and nonsocial cognition showed generally weak relations with community integration, though social cognition showed a few relations. The consistent findings across samples point to the importance of motivational factors for understanding the determinants of poor community integration in this complex population. Further, interventions that target motivational challenges may have widespread usefulness for enhancing community integration outcomes beyond obtaining housing.

Youth with perinatally-acquired HIV (PHIV) experience specific and global cognitive deficits at increased rates compared to typically-developing HIV-uninfected youth. In youth with PHIV, HIV infects the brain early in development. Neuroimaging studies have demonstrated altered grey matter morphometry in youth with PHIV compared to typically-developing youth. This study examined cortical thickness, surface area, and gyrification of grey matter in youth (age 11-20 years old) with PHIV (n = 40) from the Pediatric HIV/AIDS Cohort Study (PHACS) compared to typically-developing presumed HIV uninfected and unexposed youth (n = 80) from the Pediatric Imaging, Neurocognition and Genetics Study (PING) using structural magnetic resonance imaging. This study also examined the relationship between grey matter morphometry and age. Youth with PHIV had reduced cortical thickness, surface area, and gyrification compared to typically-developing youth. In addition, an inverse relationship between age and grey matter volume was found in typically-developing youth, but was not observed in youth with PHIV. Longitudinal studies are necessary to understand the neurodevelopmental trajectory of youth with PHIV.
