Susac syndrome is a rare immune-mediated endotheliopathy affecting the microvasculature. It presents three main symptoms: encephalopathy, branch retinal artery occlusions, and hearing loss . Here we present a new case report focusing on the evolution of the cognitive profile. The patient underwent two neuropsychological examinations. The first, one month after the onset of the symptomatology, highlighted a prevalent involvement of verbal executive functions. The second, conducted six months later, revealed a global improvement in most previously deficient areas, although with the persistence of a difficulty in cognitive estimation. . This case illustrates the importance of a comprehensive analysis of patients with Susac syndrome to appreciate the whole range of cognitive deficits and reliably evaluate symptom evolution.

Brain imaging studies have recently provided some evidence in favor of covert cognitive processes that are ongoing in patients with disorders of consciousness (DoC) (e.g., a minimally conscious state and vegetative state/unresponsive wakefulness syndrome) when engaged in passive sensory stimulation or active tasks such as motor imagery. In this exploratory study, we used transcranial magnetic stimulation (TMS) of the motor cortex to assess modulations of corticospinal excitability induced by action observation in eleven patients with DoC. Action observation is known to facilitate corticospinal excitability in healthy subjects, unveiling how the observer's motor system maps others' actions onto her/his motor repertoire. Additional stimuli were non-biological motion and acoustic startle stimuli, considering that sudden and loud acoustic stimulation is known to lower corticospinal excitability in healthy subjects. The results indicate that some form of motor resonance is spared in a subset of patients with DoC, with some significant difference between biological and non-biological motion stimuli. However, there was no covariation between corticospinal excitability and the type of DoC diagnosis (i.e., whether diagnosed with VS/UWS or MCS). Similarly, no covariation was detected with clinical changes between admission and discharge in clinical outcome measures. Both motor resonance and the difference between the resonance with biological/non-biological motion discrimination correlated with the amplitude of the N20 somatosensory evoked potentials, following the stimulation of the median nerve at the wrist (i.e., the temporal marker signaling the activation of the contralateral primary somatosensory cortex). Moreover, the startle-evoking stimulus produced an anomalous increase in corticospinal excitability, suggesting a functional dissociation between cortical and subcortical circuits in patients with DoC. Further work is needed to better comprehend the conditions in which corticospinal facilitation occurs and whether and how they may relate to individual clinical parameters.

The COVID-19 pandemic has affected the mental health of those who survived the illness but underwent long treatment and hospitalization. Much research has highlighted signs of emotional distress in those who experienced intensive care, and the procedures implemented to fight the infection. The present study investigated the effects of the illness experience in 40 subjects admitted to a rehabilitation unit after discharge from intensive care by focusing on the possibility of differences in emotional well-being depending on the type of ventilation. The results of the administration of psychological scales for anxiety, depression, and post-traumatic stress disorder showed that many subjects experienced some form of emotional distress. There were no differences between patients who underwent invasive ventilation and those who did not.

Objectives: To verify whether trunk control test (TCT) upon admission to intensive inpatient post-stroke rehabilitation, combined with other confounding variables, is independently associated with discharge mBI., Design: Multicentric retrospective observational cohort study., Setting: Two Italian inpatient rehabilitation units., Participants: A total of 220 post-stroke adult patients, within 30 days from the acute event, were consecutively enrolled., Interventions: Not applicable., Main Outcome Measure: The outcome measure considered was the modified Barthel Index (mBI), one of the most widely recommended tools for assessing stroke rehabilitation functional outcomes., Results: All variables collected at admission and significantly associated with mBI at discharge in the univariate analysis (TCT, mBI at admission, pre-stroke modified Rankin Scale [mRS], sex, age, communication ability, time from the event, Cumulative Illness Rating Scale, bladder catheter, and pressure ulcers) entered the multivariate analysis. TCT, mBI at admission, premorbid disability (mRS), communication ability and pressure ulcers (P<.001) independently predicted discharge mBI (adjusted R 2 =68.5%). Concerning the role of TCT, the model with all covariates and without TCT presented an R 2 of 65.1%. On the other side, the model with the TCT only presented an R 2 of 53.1%. Finally, with the inclusion of both TCT and all covariates, the model showed an R 2 increase up to 68.5%., Conclusions: TCT, with other features suggesting functional/clinical complexity, collected upon admission to post-acute intensive inpatient stroke rehabilitation, independently predicted discharge mBI., (Copyright © 2023 American Congress of Rehabilitation Medicine.

Background: The complexity of stroke sequelae, the heterogeneity of outcome measures and rehabilitation pathways, and the lack of extensively validated prediction models represent a challenge in predicting stroke rehabilitation outcomes., Aim: To prospectively investigate a multidimensional set of variables collected at admission to inpatient post-stroke rehabilitation as potential predictors of the functional level at discharge., Design: Multicentric prospective observational study., Setting: Patients were enrolled in four Intensive Rehabilitation Units (IRUs)., Population: Patients were consecutively recruited in the period December 2019-December 2020 with the following inclusion criteria: aged 18+, with ischemic/haemorrhagic stroke, and undergoing inpatient rehabilitation within 30 days from stroke., Methods: This is a multicentric prospective observational study. The rehabilitation pathway was reproducible and evidence-based. The functional outcome was disability in activities of daily living, measured by the modified Barthel Index (mBI) at discharge. Potential multidimensional predictors, assessed at admission, included demographics, event description, clinical assessment, functional and cognitive profile, and psycho-social domains. The variables statistically associated with the outcome in the univariate analysis were fed into a multivariable model using multiple linear regression., Results: A total of 220 patients were included (median [IQR] age: 80 [15], 112 women, 175 ischemic). Median mBI was 26 (43) at admission and 62.5 (52) at discharge. In the multivariable analysis younger age, along with better functioning, fewer comorbidities, higher cognitive abilities, reduced stroke severity, and higher motor functions at admission, remained independently associated with higher discharge mBI. The final model allowed a reliable prediction of discharge functional outcome (adjusted R 2 =77.2%)., Conclusions: The model presented in this study, based on easily collectable, reliable admission variables, could help clinicians and researchers to predict the discharge scores of the global functional outcome for persons enrolled in an evidence-based inpatient stroke rehabilitation program., Clinical Rehabilitation Impact: A reliable outcome prediction derived from standardized assessment measures and validated treatment protocols could guide clinicians in the management of patients in the subacute phase of stroke and help improve the planning of the rehabilitation individualized project.

A domain-specific perspective to cognitive functioning in stroke patients may predict their cognitive recovery over time and target stroke rehabilitation intervention. However, data about domain-specific cognitive impairment after stroke are still scarce. This study prospectively investigated the domain-specific pattern of cognitive impairments, using the classification proposed by the Montreal Cognitive Assessment (MoCA), in a cohort of 49 stroke patients at admission (T0), discharge (T1), and six-month follow-up (T2) from subacute intensive rehabilitation. The predictive value of T0 cognitive domains cognitive impairment at T1 and T2 was also investigated. Patients' cognitive functioning at T0, T1, and T2 was assessed through the MoCA domains for executive functioning, attention, language, visuospatial, orientation, and memory. Different evolutionary trends of cognitive domain impairments emerged across time-points. Patients' impairments in all domains decreased from T0 to T1. Attention and executive impairments decreased from T0 to T2 (42.9% and 26.5% to 10.2% and 18.4%, respectively). Conversely, altered visuospatial, language, and orientation increased between T1 and T2 (16.3%, 36.7%, and 40.8%, respectively). Additionally, patients' global cognitive functioning at T1 was predicted by the language and executive domains in a subacute phase ( p = 0.031 and p = 0.001, respectively), while in the long term, only attention ( p = 0.043) and executive ( p = 0.019) domains intervened. Overall, these results confirm the importance of a domain-specific approach to target cognitive recovery across time in stroke patients.

Background: Impairment of executive functions is a frequent and disabling consequence of brain injury. In 1991, Shallice and Burgess elaborated the Multiple Errand Test (MET) to assess everyday troubles associated with this impairment., Objective: Our first aim was to create a generic version of MET (MET-G) readily adaptable to different settings and for retesting. The second aim was to validate the revised version to detect executive impairment in individuals with severe ABI., Methods: An inter-professional team of experts in neurorehabilitation created a revised version of MET. Twenty-one patients with sABI (severe Acquired Brain Injury) and a control group of 20 neurologically healthy subjects, took part in the testing of MET-G., Results: MET-G clearly distinguished people with sABI from healthy controls based on Total error score, task completion, and rule breaking. The test showed good inter-rater reliability and internal consistency., Conclusions: The new, generic version of MET was able to differentiate adults with sABI from controls and proved to be a good tool for evaluating executive functions in these patients in daily-life contexts. Indications on how to adapt the test to different contexts and different scoring modalities are provided.

Background: Community ambulation ability is one of the most important functional loss after stroke. The assessment of the level of community walking plays an important role in the multidimensional bio-psycho-social approach, to improve quality of life and social participation of stroke survivors. The modified Functional Walking Categories (mFWC) is a worldwide widely used tool to assess community ambulation in stroke survivors, but no Italian version is yet available., Objective: To cross-culturally adapt the mFWC into Italian and to assess its validity and reliability., Methods: According to the international guidelines, a multistep translation and cultural adaptation were conducted and revised by a committee of experts. Patients admitted to intensive inpatient rehabilitation with a sub-acute stroke were recruited. Inter- and intra-rater reliability and construct validity were studied., Results: Sixty patients with sub-acute stroke were prospectively enrolled in this study. Findings showed almost perfect intra- and inter-rater reliability (k = 1.000 [95% CI 1.000-1.000] and k = 0.984 [95% CI 0.955-1.000], respectively). The construct validity of the scale was satisfactory, as 100.0% a-priori hypotheses were met., Conclusions: The Italian mFWC offers a valid tool for measuring community ambulation in stroke patients. Our work provides a validated and a cross-cultural adapted Italian version of the mFWC to accurately measure community ambulation both in clinical and research settings in Italy.

Purpose: To assess the intra- and inter-rater reliability motor and sensory functioning, balance, joint range of motion and joint pain subscales of the Italian Fugl-Meyer Assessment (FMA) Upper Extremity (FMA-UE) and Lower Extremity (FMA-LE) at the item- subtotal- and total-level in patients with sub-acute stroke., Materials and Methods: The FMA was administered to 60 patients with sub-acute stroke (mean age ± SD = 75.4 ± 10.7 years; 58.3% men) and independently rated by two physiotherapists on two consecutive days. Intra- and inter-reliability was studied by a rank-based statistical method for paired ordinal data to detect any systematic or random disagreement., Results: The item-level intra- and inter-rater reliability was satisfactory (>70%). Reliability level >70% was achieved at subscale and total score level when one- or two-points difference was considered. Systematic disagreements were reported for five items of the FMA-UE, but not for FMA-LE., Conclusions: The Italian version of the FMA showed to be a reliable instrument that can therefore be recommended for clinical and research purposes.Implications for rehabilitationThe FMA is the gold standard for assessing stroke patients' sensorimotor impairment worldwide.The Italian Fugl-Meyer Assessment of Upper Extremity (FMA-UE) and Lower Extremity (FMA-LE) is substantially reliable within and between two raters at the item, subtotal, and total score level in patients with sub-acute stroke.The use of FMA in the Italian context will provide an opportunity for international comparisons and research collaborations.

Background: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) represents the most recent severe pandemic resulting in coronavirus disease 2019 (COVID-19). COVID-19 can damage the central nervous system, requiring admission to intensive care units (ICU) and aggressive treatments (long-term ventilatory assistance and sedation) to stabilize vitals. Most post-COVID-19 patients experience cognitive impairments and mood or stress disorders. We aimed to study the frequency of cognitive deficits in COVID-19 survivors, the relationship between clinical factors in the acute phase and cognitive outcomes, affective states, and quality of life. We explored cognitive reserve (CR) role, as a post-COVID-19 resilience factor., Methods: Twenty-nine COVID-19 inpatients were assessed using a neuropsychological battery, mood scales, quality of life, and social integration questionnaires. Twenty-five were retained through telephone follow-up to monitor cognitive sequelae, affective states, and reintegration levels roughly 8 months after hospital discharge. We administered the Cognitive Reserve Index questionnaire., Results: We found most patients display no cognitive deficits. When they did, multi-domain impairment occurred most frequently, especially involving executive functions. Results revealed a significant correlation between depression levels and the interval between ICU admission and tracheal tube removal. We found increased levels of depression and anxiety at follow-up, a significant relationship between resuming daily life activities, high CR, and executive functions., Conclusions: These findings suggest the importance of psychological support in the long term and the modulating role of cognitive reserve in quality of life after infection., (© 2023.

Background: Stroke survivors report physical, cognitive, and psychological impairments, with a consequent limitation of participation. Participation is the most context-related dimension of functioning, but the literature on participation in Italian stroke patients is scant., Aim: This study aimed to describe the recovery of participation six months after stroke with a validated Italian version of the Frenchay Activity Index (FAI) and to investigate potential correlates with higher participation scores., Design: The study is a prospective observational study., Setting: The cohort of patients was enrolled in four intensive inpatient rehabilitation units of IRCCS Fondazione Don Carlo Gnocchi Onlus, Florence, Italy., Population: Adults addressing postacute intensive inpatient rehabilitation after an ischemic or hemorrhagic stroke occurred within 30 days from recruitment were prospectively enrolled., Methods: Data were collected at admission to intensive inpatient rehabilitation, and a six-month follow-up. The primary outcome was participation, measured by a validated Italian version of the FAI; only patients whose data included both anamnestic FAI and FAI at six months follow-up were included in this analysis. The data were analyzed by univariate and multivariate linear regressions., Results: A cohort of 105 patients (median age 78 years [interquartile range, IQR=21]; 46.7% males) with completed FAI at follow-up were included in this study. The sample reported a FAI median score of 28 (IQR=8) at admission (referred to the participation in the 3-6 months before the stroke) and 13 (IQR=20) at follow-up. All items were significantly affected, with the exception of reading and making trips. The multivariate regression for all patients with good participation before the stroke (N.=101), showed that 6 months after the stroke a higher FAI Score was independently associated with better functioning in activities of daily living (modified Barthel Index) (B=0.133; P=0.015), and absence of cognitive impairment (B=4.755; P=0.027); a lower stroke severity in the postacute phase (NIHSS B=-0.832; P=0.001) and a higher prestroke FAI Score (B=0.410; P=0.028) were also independently related to follow-up FAI Score., Conclusions: In our cohort of patients addressing postacute stroke rehabilitation, prestroke participation levels were on average good, while they were severely reduced six months after stroke for all the considered items except reading and making trips. Higher FAI at follow-up was independently associated with a higher functional level and no cognitive impairment at follow-up, with lower stroke severity in the postacute phase, as well as a higher anamnestic participation score., Clinical Rehabilitation Impact: Our results suggest that investigating prestroke participation may be highly relevant to predict, and possibly address, participation recovery after stroke.

Background: Trunk control plays a crucial role in the stroke rehabilitation, but it is unclear which factors could influence the trunk control after an intensive rehabilitation treatment., Objectives: To study which demographic, clinical and functional variables could predict the recovery of trunk control after intensive post-stroke inpatient rehabilitation., Methods: Subjects with acute, first-ever stroke were enrolled and clinical and data were collected at admission and discharge. The primary outcome was considered the trunk control measured by the Trunk Control Test (TCT). The data were analyzed by a univariate and multivariate logistic regressions., Results: Two hundred forty-one post-stroke patients were included. All baseline variables significantly associated to TCT at discharge in the univariate analysis (i.e. gender, NIHSS neglect item at admission, presence of several complexity markers, TCT total score at admission, NIHSS total score, pre-stroke modified Rankin Scale, Fugl-Meyer Assessment motor and sensitivity score) were entered in the multivariate analysis. The multivariate regression showed that age ( p = .003), admission NIHSS total score ( p = .001), admission TCT total score ( p < .001) and presence of depression ( p = .027) independently influenced the TCT total score at discharge ( R 2  = 61.2%)., Conclusions: Age, admission neurological impairment (NIHSS total score), trunk control at the admission (TCT total score), and presence of depression independently influenced the TCT at discharge. These factors should be carefully assessed at the baseline to plan a tailoring rehabilitation treatment achieving the best trunk control performance at discharge.

A growing number of scientific contributions suggest that COVID-19 infection can lead to impairment of cognition, mainly in executive functions and memory domains, even in the absence of frank neurological pathologies.The primary objective of this retrospective study is to evaluate the frequency and type of inefficiencies in a selection of cognitive tests administered to a sample of subjects who, following infection, required invasive assisted ventilation and were admitted to rehabilitation wards for the treatment of functional impairment.Fifty-seven subjects were enrolled. The recruited patients undergone an assessment of verbal and visuospatial memory and executive functions, upon entry into the rehabilitation department, after discharge from intensive care. The following tests were administered: Rey Auditory Verbal Learning Test (AVLT) (immediate and delayed recall), Rey-Osterrieth Complex Figure Test (ROCFT) (copy and delayed recall), Stroop Color-Word Test, and Trail Making Test (TMT, A and B).Deficient scores, in beyond 25% of subjects, were found in the copy of the ROCFT (32.1% of subjects), and in the delayed recall of ROCFT (27.2%). Between 10 and 20% of patients presented an abnormal result in delayed recall of AVLT (16.07%), and Stroop Test (time, 15.6%, error, 11.5%). Less than 10% of the sample had abnormal performances on TMT (A, 3.5%, and B, 9.4%), and in AVLT immediate recall (8.9%). Correlations of the performances with age, sex, and education were also found.This paper highlights the high incidence of abnormal cognitive performances in this specific subpopulation of patients with COVID-19 infection.

In a recent study we showed that Cognitive Reserve (CR) did not significantly predict the neuropsychological outcomes of patients with severe Acquired Brain Injury (sABI), after a rehabilitation program. The present study aims to extend the previous results by assessing the role of CR on long-term neuropsychological outcomes of a subgroup ( N  = 27) of that same population. Patients took part in a telephone interview, where Tele-Global Examination Mental State (Tele-GEMS) and Glasgow Outcome Scale Extended (GOS-E) were administered. A linear regression model was conducted considering Tele-GEMS and GOS-E as dependent variables, while the scores on Cognitive Reserve Index questionnaire (CRIq), Disability Rating Scale (DRS), and Level of Cognitive Functioning (LCF), administered at discharge, were considered as predictors. Results show that higher levels of CR and LCF, significantly predicted cognitive performance 4 years later. However, in the same follow-up, CR did not predict functional outcome, which was only predicted by lower disability scores at discharge. Thus, even if CR seems not showing an effect on cognitive efficiency when tested after the first rehabilitation intervention, current results show that CR has significant effects on long-term cognitive outcomes.

Dysphagia represents one of the most frequent symptoms in the post-acute stroke population. Swallowing impairment and cognitive deficits can often co-occur. This study aims to investigate the relationship between cognitive impairment and the recovery of dysphagia in patients attending specific rehabilitation. Patients admitted to intensive rehabilitation units were administered the Functional Oral Intake Scale (FOIS) and Montreal Cognitive Screening Test (MoCA); when screening positive for dysphagia, they entered a rehabilitation program. Their FOIS score at discharge was the primary outcome measure. In the multivariate analysis, younger age (B = - 0.077, p  = 0.017), higher MoCA (B = 0.191, p  = 0.002), and higher FOIS (B = 1.251, p  = 0.032) at admission were associated with higher FOIS at discharge. When executive function (EF) replaced the MoCA total score in the model, younger age (B = - 0.134, p  = 0.001), higher admission EF (B = 1.451, p  < 0.001), and FOIS (B = 1.348, p  = 0.035) were associated with higher FOIS at discharge. Our results confirm the hypothesis that a better cognitive profile upon admission is associated with a higher probability of dysphagia recovery at discharge. EF seems to have a crucial role in dysphagia recovery. These results highlight the importance of considering the cognitive profile when assessing and treating dysphagia after stroke and of using screening tests that include executive functions., Competing Interests: The authors declare that they have no relevant or material financial interests that relate to the research described in this article., (Thieme.

Background: The Token Test (TT) is widely used to examine comprehension disorders in aphasic patients, but abilities other than language may affect a patient's performance. This study aims to explore the correlation between the TT subtest performances and the performances in extra-linguistic cognitive areas in a cohort of patients from the Intensive Rehabilitation Post-Stroke (RIPS) study with a first, right hemisphere stroke and without aphasia, prospectively enrolled at admission to intensive inpatient post-acute rehabilitation., Methods: The patients were administered the TT (50-item version), the forward and backward digit span (DST), and the Montreal Cognitive Assessment (MoCA). Spearman's partial correlations adjusted by age were used to evaluate the association between the number of errors in the TT and the other tests' corrected scores., Results: Of the 37 patients enrolled in this study, 29.7% made 3-11 errors on the TT, 27.0% more than 11 errors, mostly in parts IV and V. The forward and backward digit span scores showed correlations with errors in part V of the TT (r = -0.408, p = 0.013; r = -0.307, p = 0.027). The errors in part IV of the TT presented a correlation with a forward digit span too (r = -0.394, p = 0.017). With respect to MoCA domains, executive functioning, and orientation were related to the TT part V errors (r = -0.468, p = 0.007; r = -0.499, p = 0.003). The orientation also correlated with the TT part III (r = -0.504, p = 0.002)., Conclusion: Our findings show that the TT performances in patients with right hemisphere stroke and without aphasia are related to impairments in auditory-verbal span/auditory working memory mostly for TT scores on subpart V as measured by the DST and to executive function and orientation, as measured by the MoCA subtests.

Background: Stroke represents the second preventable cause of death after cardiovascular disease and the third global cause of disability. In countries where national registries of the clinical quality of stroke care have been established, the publication and sharing of the collected data have led to an improvement in the quality of care and survival of patients. However, information on rehabilitation processes and outcomes is often lacking, and predictors of functional outcomes remain poorly explored. This paper describes a multicenter study protocol to implement a Stroke rehabilitation Registry, mainly based on a multidimensional assessment proposed by the Italian Society of Physical and Rehabilitation Medicine (PMIC2020), in a pilot Italian cohort of stroke survivors undergoing post-acute inpatient rehabilitation, to provide a systematic assessment of processes and outcomes and develop data-driven prediction models of functional outcomes., Methods: All patients with a diagnosis of ischemic or haemorrhagic stroke confirmed by clinical assessment, admitted to intensive rehabilitation units within 30 days from the acute event, aged 18+, and providing informed consent will be enrolled. Measures will be taken at admission (T0), at discharge (T1), and at follow-up, 3 months (T2) and 6 months (T3) after the stroke. Assessment variables include anamnestic data, clinical and nursing complexity information and measures of body structures and function, activity and participation (PMIC2020), rehabilitation interventions, adverse events and discharge data. The modified Barthel Index will be our primary outcome. In addition to classical biostatistical analysis, learning algorithms will be cross-validated to achieve data-driven prognosis prediction models., Conclusions: This study will test the feasibility of a stroke rehabilitation registry in the Italian health context and provide a systematic assessment of processes and outcomes for quality assessment and benchmarking. By the development of data-driven prediction models in stroke rehabilitation, this study will pave the way for the development of decision support tools for patient-oriented therapy planning and rehabilitation outcomes maximization., Clinical Tial Registration: The registration on ClinicalTrials.gov is ongoing and under review. The identification number will be provided when the review process will be completed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Chiavilli, Campagnini, Baretta, Castagnoli, Paperini, Politi, Pellicciari, Baccini, Basagni, Marignani, Bardi, Sodero, Lombardi, Guolo, Navarro, Galeri, Montesano, Falco, Rovaris, Carrozza, Macchi, Mannini and Cecchi.)

Background: Rehabilitation treatments and services are essential for the recovery of post-stroke patients' functions; however, the increasing number of available therapies and the lack of consensus among outcome measures compromises the possibility to determine an appropriate level of evidence. Machine learning techniques for prognostic applications offer accurate and interpretable predictions, supporting the clinical decision for personalised treatment. The aim of this study is to develop and cross-validate predictive models for the functional prognosis of patients, highlighting the contributions of each predictor., Methods: A dataset of 278 post-stroke patients was used for the prediction of the class transition, obtained from the modified Barthel Index. Four classification algorithms were cross-validated and compared. On the best performing model on the validation set, an analysis of predictors contribution was conducted., Results: The Random Forest obtained the best overall results on the accuracy (76.2%), balanced accuracy (74.3%), sensitivity (0.80), and specificity (0.68). The combination of all the classification results on the test set, by weighted voting, reached 80.2% accuracy. The predictors analysis applied on the Support Vector Machine, showed that a good trunk control and communication level, and the absence of bedsores retain the major contribution in the prediction of a good functional outcome., Conclusions: Despite a more comprehensive assessment of the patients is needed, this work paves the way for the implementation of solutions for clinical decision support in the rehabilitation of post-stroke patients. Indeed, offering good prognostic accuracies for class transition and patient-wise view of the predictors contributions, it might help in a personalised optimisation of the patients' rehabilitation path., (© 2022.

Purpose: Participation needs to be assessed objectively, to state accurate rehabilitation objectives. The Frenchay Activities Index (FAI) is a widely used tool to measure participation in stroke patients. To date, no cross-culturally validated Italian version of FAI is available. This study provides a translation and cross-cultural adaptation of FAI into Italian, assessing its validity and reliability in sub-acute stroke patients., Methods: According to international guidelines, a multistep translation and cultural adaptation protocol of forward and backward translations was conducted by qualified linguists and independent native English translators and revised by a healthcare committee. Patients admitted to intensive inpatient rehabilitation after stroke were recruited. Structural validity, reliability (internal consistency, inter- and intra-rater reliability and measurement error), and construct validity were studied., Results: One hundred and seventy-three patients were included in this study. No significant observations in terms of comprehensibility and conceptual equivalence of the FAI Italian version emerged. The exploratory factorial analysis revealed the presence of two subscales (i.e., domestic chores and work/leisure). The internal consistency resulted good for the first and second subscale (α = 0.821 and 0.716, respectively). Intra- and inter-reliability showed an ICC > 0.90 for both subscales. SEM = 5.75% and 2.33% and MDC = 15.85% and 6.48% were found for the first and second subscale, respectively. Construct validity of first subscale was satisfactory, as 100.0% a priori hypotheses were met, while for the second subscale it was moderate, as 66.6% a priori hypotheses were respected., Conclusion: FAI-I provides a tool for professionals to measure participation in Italian stroke patients in health and social care settings., (© 2022.

Background: Many variables affect outcome after brain injury. Cognitive reserve (CR) is a subjective factor that reflects a set of personal characteristics and that differentiates individuals. It may influence an individual's capacity to react to brain injury., Objective: To study the effects of cognitive reserve on functional and cognitive outcome at the end of rehabilitation, in patients with severe acquired brain injury (sABI), by means of the Cognitive Reserve Index questionnaire (CRIq)., Methods: We report a retrospective study of a continuous series of sABI patients on first admission to a rehabilitation center. Disability and cognitive outcomes were recorded., Results: In the 94 patients enrolled, the assessments after rehabilitation showed a significant gain measured with the disability Rating Scale for patients with a higher CR (CRIq≥ 85). A significant negative correlation was found: between CRIq scores and the interval elapsing before first access to neuropsychological assessment, between CRIq scores, especially level of education, and tests that measure the same domain (attention)., Conclusions: Improvements in overall and cognitive disability emerged, but CR did not seem to substantially influence outcome in this sample of patients. This result may be partly due to the clinical severity of the population studied and the sample's dimension, although quantitatively representative of the population.

Objectives: This study aims to evaluate the diagnostic performance of NIHSS extinction and inattention item, compared to the results of the Oxford Cognitive Screen (OCS) heart subtest. Additionally, the possible role of the NIHSS visual field subtest on the NIHSS extinction and inattention subtest performance is explored and discussed., Methods: We analysed scores on NIHSS extinction and inattention subtest, NIHSS visual field subtest, and OCS heart subtest on a sample of 118 post-stroke patients., Results: Compared to OCS heart subtest, the results on NIHSS extinction and inattention subtest showed an accuracy of 72.9% and a moderate agreement level (Cohen's kappa = 0.404). Furthermore, a decrease in NIHSS accuracy detecting neglect (61.1%) was observed in patients with pathological scores in NIHSS visual field item., Conclusions: Extreme caution is recommended for the diagnostic performance of extinction and inattention item of NIHSS. Signs of neglect may not be detected by NIHSS, and may be confused with visual field impairment., Trial Registration: This study refers to an observational study protocol submitted to ClinicalTrials.gov with identifier: NCT03968627 . The name of the registry is "Development of a National Protocol for Stroke Rehabilitation in a Multicenter Italian Institution" and the date of the registration is the 30th May 2019., (© 2021.

We describe the case of a bilingual patient with persistent symptoms largely, although not fully, consistent with those that are usually reported in Gerstmann's syndrome. Twenty months after a spontaneous primary intracranial hemorrhage, the patient was evaluated with a series of neuropsychological tasks and underwent an MRI investigation based on Diffusion Tensor Imaging probabilistic tractography. The patient suffered from dysgraphia (difficulty in the access to the graphemic representation of letter forms), autotopoagnosia (difficulties in locating body parts on verbal command), right-left confusion (difficulties in localizing right and left side of symmetrical body parts), and number processing/calculation impairments (predominant difficulties on transcoding tasks). Probabilistic tractography revealed a relatively spared superior longitudinal fasciculus and severe damage to the subcortical white matter connecting the angular gyrus with other parietal regions, such as the intraparietal sulcus and the supramarginal gyrus. Within the framework of the contemporary cognitive accounts of Gerstmann's syndrome, the case supports the assumption of an anatomical intraparietal disconnection more than a functional Grundstörung (core impairment)., (Copyright © 2020 Elsevier Inc.

Background: Previous analyses demonstrated a lack of unidimensionality, item redundancy, and substantial administrative burden for the Brain Injury Rehabilitation Trust Personality Questionnaires (BIRT-PQs)., Objective: To use Rasch Analysis to calibrate five short-forms of the BIRT-PQs, satisfying the Rasch model requirements., Methods: BIRT-PQs data from 154 patients with severe Acquired Brain Injury (s-ABI) and their caregivers (total sample = 308) underwent Rasch analysis to examine their internal construct validity and reliability according to the Rasch model., Results: The base Rasch analyses did not show sufficient internal construct validity according to the Rasch model for all five BIRT-PQs. After rescoring 18 items, and deleting 75 of 150 items, adequate internal construct validity was achieved for all five BIRT-PQs short forms (model chi-square p -values ranging from 0.0053 to 0.6675), with reliability values compatible with individual measurements., Conclusions: After extensive modifications, including a 48% reduction of the item load, we obtained five short forms of the BIRT-PQs satisfying the strict measurement requirements of the Rasch model. The ordinal-to-interval measurement conversion tables allow measuring on the same metric the perception of the neurobehavioral disability for both patients with s-ABI and their caregivers.

Objective : To assess the internal construct validity (ICV) of the five Brain Injury Rehabilitation Trust Personality Questionnaires (BIRT-PQ) with Classical Test Theory methods. Methods : Multicenter cross-sectional study involving 11 Italian rehabilitation centers. BIRT-PQs were administered to patients with severe Acquired Brain Injury and their respective caregivers. ICV was assessed by the mean of an internal consistency analysis (ICA) and a Confirmatory Factor Analysis (CFA). Results : Data from 154 patients and their respective caregivers were pooled, giving a total sample of 308 subjects. Despite good overall values (alphas ranging from 0.811 to 0.937), the ICA revealed that several items within each scale did not contribute as expected to the total score. This result was confirmed by the CFA, which showed the misfit of the data to a unidimensional model (RMSEA ranging from 0.077 to 0.097). However, after accounting for local dependency found within the data, fitness to a unidimensional model improved significantly (RMSEA ranging from 0.050 to 0.062). Conclusion : Despite some limitations, our analyses demonstrated the lack of ICV for the BIRT-PQ total scores. It is envisaged that a more comprehensive ICV analysis will be performed with Rasch analysis, aiming to improve both the measurement properties and the administrative burden of each BIRT-PQ.

Objective: Symptoms of visuospatial neglect occur frequently after unilateral brain damage. Neglect hampers general rehabilitation progress and is associated with reduced quality of life. Some of the rehabilitation programs developed to treat neglect have demonstrated behavioral improvements. However, only a few of them have addressed specifically the anatomo-functional correlates associated behavioral improvement., Method: Here we describe the case of a patient (GV) with a severe left neglect disorder as a consequence of a right hemisphere stroke. Eighteen weeks after the onset, he underwent a 10-week intensive neuropsychological rehabilitation program. Functional MRI (fMRI) during execution of a covert attention task, and a broad neuropsychological assessment were conducted before and after the training., Results: The results show a significant improvement of the performance in neglect tasks after the rehabilitation program, although the remission of symptoms was not complete. fMRI data showed that the behavioral improvement was accompanied by an increase of activity in the dorsal premotor cortex and middle frontal gyrus bilaterally. Other activations were present only in the contralesional left hemisphere, including supplementary motor area and superior temporal gyrus., Conclusions: The implications of the results are discussed.

Objective: The Bells Test is a cancelation task that is widely used for the diagnosis of unilateral spatial neglect (USN). With the aim of fostering more reliable use of this instrument, we set out to develop new norms adjusted for the possible influence of age, gender and education. We worked on the original version of the test. Methods: Normative data were collected from 401 healthy participants aged between 20 and 80 years. Individual factors that could affect performance (i.e., gender, age, and years of education) were considered. We computed several indices on the Bells Test including an asymmetry score, an accuracy score and execution time. Multiple regression analyses (for time measures) and generalized linear models (for accuracy measures) were used to check for the influence of individual predictors of performance on the Bells Test. Results: Data indicated a significant influence of age on the accuracy score and execution time variables and a marginally significant effect of education on the accuracy score variable. Wherever appropriate, cut-offs are provided for the three dependent scores on the Bells Test corrected for age and education. Conclusion: Based on a large normative sample, the present study provides new normative data on the Bells Test, which could lead to its reliable use in the diagnosis of USN.

Background: Driving is a complex ability requiring a broad range of motor, cognitive-behavioral and visual skills that may be impaired after severe acquired brain injury (sABI). Resumption of driving is perceived as a major need by patients, being closely linked to personal autonomy, work and social activities., Aim: The objective of this study was to identify a short battery of neuropsychological tests with predictive value with regard to safe return to driving after sABI., Design: Observational study., Setting: Outpatient of a rehabilitation center for sABI., Population: A continuous series of 127 patients with stable sABI, well-reintegrated at a family and social level, dismissed since at least one year from the end of their intensive rehabilitation, enrolled between 2006 and 2014., Methods: Patients underwent an extensive battery of neuropsychological tests (pencil and paper and specific PC programs), aimed at assessing cognitive functions, in performance and verbal tasks. The results were analyzed in relation to their on-road performance during the driving test conducted by the office of the Italian Government Authority (success or failure of the test)., Results: No correlations were found between demographic data, etiology, driving experience, verbal competence and the decision of the competent authority. Significant correlation was found between attention, executive functions, overall visual-spatial exploration and driving performance., Conclusions: Both "pencil and paper" and computerized tests in the cognitive domains of attentive functions, and those involving performance with visual-spatial material, are significantly correlated with the driving test outcome, even if there is not enough evidence of the relative value of off-road compared to direct on-road tests., Clinical Rehabilitation Impact: We propose a small neuropsychological battery of tests with normative data for Italian population, predictive with respect to the ability to drive safely. We recommend to use it as first screening before submitting patients to more demanding and risky on-road driving tests.

Unilateral spatial neglect (USN) is a frequent consequence of acquired brain injury, especially following right hemisphere damage. Traditionally, unilateral spatial neglect is assessed with cancellation tests such as the Bells test. Recently, a new cancellation test, the Apples test, has been proposed. The present study aims at comparing the accuracy of these two tests in detecting hemispatial neglect, on a sample of 56 right hemisphere stroke patients with a diagnosis of USN. In order to evaluate the agreement between the Apples and Bells tests, Cohen's kappa and McNemar's test were used to assess differences between the two methods of evaluation. Poor agreement and statistically significant differences emerged between the Apples and Bells tests. Overall, the Apples test was significantly more sensitive than the Bells test in detecting USN. Based on these results, the use of the Apples test for peripersonal neglect assessment is therefore highly recommended.

Verbal reasoning is a complex, multicomponent function, which involves activation of functional processes and neural circuits distributed in both brain hemispheres. Thus, this ability is often impaired after brain injury. The aim of the present study is to describe the construction of a new verbal reasoning test (VRT) for patients with brain injury and to provide normative values in a sample of healthy Italian participants. Three hundred and eighty healthy Italian subjects (193 women and 187 men) of different ages (range 16-75 years) and educational level (primary school to postgraduate degree) underwent the VRT. VRT is composed of seven subtests, investigating seven different domains. Multiple linear regression analysis revealed a significant effect of age and education on the participants' performance in terms of both VRT total score and all seven subtest scores. No gender effect was found. A correction grid for raw scores was built from the linear equation derived from the scores. Inferential cut-off scores were estimated using a non-parametric technique, and equivalent scores were computed. We also provided a grid for the correction of results by z scores.

Primary Objective: To report consistent recovery of consciousness to a state of severe disability in a young patient after 7 years in vegetative state due to severe acquired brain injury, with reflections on protraction of intensive care and expert follow-up for the purpose of intercepting possible, albeit infrequent, cases of late recovery of consciousness., Research Design: Single case study Methods: This study describes the 9-year history of a healthy 15-year-old who suffered cerebellar haemorrhage due to rupture of an arteriovenous malformation, followed by a brief period of coma then protracted vegetative state; late stabilization of general condition with resolution of neurosurgical complications. Clinical monitoring employed scales for structured assessment of severe disability and disorders of consciousness., Results: The transition from vegetative state to full consciousness occurred over a period of ~ 3 months, 7 years after onset. In the subsequent 2 years the patient has shown slow but progressive overall improvement in a framework of severe residual motor and cognitive disability., Conclusions: Cases of recovery of consciousness after periods of vegetative state exceeding 1 year are rare, but remind one that a negative prognosis decided too early may be a self-fulfilling forecast.

We describe the case of a non-alcoholic patient with chronic myeloid leukemia who developed iatrogenic Wernicke's encephalopathy (WE) following stem cell transplantation. Four years after the WE acute event, the patient's cognitive profile was mainly characterized by moderate memory impairment, and functional and daily-living difficulties. Our report sustains the hypothesis that a iatrogenic form of WE may produce long-term cognitive sequelae even when thiamine therapy is administered in the acute phase until the resolution of the neurological signs.

The aim of this study was to describe the translation and adaptation of the BIRT personality questionnaires for the Italian population. This included the replication of validity testing and the collection of normative data. Following translation and adaptation according to cross-cultural guidelines, the questionnaires were administered as a pre-test to a sample of 20 healthy subjects and then to 10 patients. The questionnaires were then administered to 120 healthy subjects equally distributed by sex, education, and age, to collect normative data from an Italian population. The questionnaires were easily administered to both healthy subjects and patients. Statistical analysis on normative data was conducted to find the mean value for each questionnaire. This study lays the foundations for using a new instrument to assess behavioral changes after acquired brain injury on the Italian population.

We describe a right-handed patient (M.B.), who developed left hemianopsia and a severe reading impairment after right occipital-parietal hemorrhage. The pattern of his reading deficit was very similar to that of pure alexia (alexia-without-agraphia): extremely slow reading times with frequent grapheme substitutions and omissions. A test of letter reading while controlling for saccadic eye movements and hemifield of presentation ruled out hemianoptic alexia. Although there have already been reports of reading impairments in right handers following right- hemispheric lesions, ours is, to the best of our knowledge, the first where visual field loss can be definitely excluded as the main cause. Based on a standard neuropsychological assessment and on additional behavioral tests, we argue that M.B.'s difficulties are unlikely to be due to right-hemisphere dominance for language. After considering several candidate explanations, we suggest that M.B.'s symptoms may be related to an impairment in attentional processes related to reading.
