Social isolation and a lack of engagement in activities are common among people with dementia living in residential care. The check‐in procedure, in which staff approach a resident to offer a choice of activities and praise engagement every 15 min, is effective in increasing engagement. However, the schedule effects of the check‐in procedure have not been previously evaluated. We assessed whether the check‐in procedure was effective with an extended check‐in interval of 30 min. We found that the procedure remained effective with a leaner schedule and that engagement persisted above baseline levels between check‐in interactions. Staff reported that the intent to increase engagement was valuable and that the procedure was easy to implement. We discuss our findings in the context of participatory interventions for dementia and the potential role of organizational factors in the adoption of evidence‐based procedures in dementia care.

INTRODUCTION: Cognition often remains unassessed in primary care. To improve early diagnosis of neurocognitive disorder (NCD) in Switzerland, the tablet-based UCSF brain health assessment (BHA) and brain health survey (BHS) were validated. METHODS: The German BHA, BHS, and Montreal Cognitive Assessment (MoCA) were administered to 67 patients with mild/major NCD and 50 controls. BHA includes subtests of memory, executive, visuospatial, and language functioning, and informant-based BHS asks about behavior and motor functioning. RESULTS: The complete instrument (BHA + BHS) was most accurate at detecting mild NCD (AUC = 0.95) and NCD without amyloid pathology (AUC = 0.96), followed by the BHA. All measures were accurate (all AUCs > 0.95) at distinguishing major NCD and NCD with amyloid pathology (Alzheimers disease [AD]) from controls. DISCUSSION: The German BHA and BHS are more sensitive to mild NCD and non-AD presentations than the MoCA and thus have a high potential to identify patients with NCD in primary care earlier than currently used screens.

Caring for a loved one with a Major Neurocognitive Disorder can be compared to a long train journey with no fixed route and no estimated time of arrival. This condition, formerly known as "dementia," is a progressive and incurable neurological disorder that impairs a person's cognitive and physical abilities. As a result, patients who had been diagnosed were left with caregivers who had the duty of caring for them. Prior studies have shown that family caregivers of patients with major neurocognitive disorders experience anticipatory grief, a stage of pre-death mourning brought on by manifestations of the disorder's impact on the patient. In the Philippines, Major Neurocognitive Disorder is not recognized as a significant public health concern that calls for an investment in medical research, causing the caregiver community to suffer and be labeled as the second invisible patient due to a lack of approved local guidelines (Agapito et al., 2018). It limits the possibility of conducting local studies on caregivers' experiences of anticipatory grief. This provided sufficient justification for the researchers to conduct a qualitative phenomenological study focusing on the family caregivers of patients with major neurocognitive disorders to determine the essence of a phenomenon of "uncertainty" through their lived experiences. Following Collaizi's methodological approach, the researchers created a self-made open-ended interview questionnaire. A total of ten selected respondents were interviewed using maximum variation sampling. The findings indicate that anticipatory grief is commonly experienced by family caregivers who have a patient with a severe major neurocognitive disorder, as it includes the disorder's worst symptoms, such as memory and functionality deterioration. The respondents reported anticipatory grief as a result of "uncertainty" caused by a lack of knowledge, resources, and support, resulting in self-doubts and a sense of helplessness. Indeed, there is uncertainty in anticipatory grief as a result of inadequate country policies for homebased family caregivers. [ABSTRACT FROM AUTHOR]

Key summary points: Aim: The purpose of the study was to assess the relationship between etiologic subtypes of major neurocognitive disorder (MND) and dehydration, and the frequency of dehydration with a particular emphasis on different MND (dementia) subtypes. Findings: The prevalence of dehydration is 58% in patient with MND and 53% in patients without MND. Dehydration is associated with dementia. Hypertension, diabetes mellitus, chronic kidney disease, dysphagia and cognitive dysfunction were associated with dehydration in patients with dementia. The prevalence of dehydration is highest in patients with vascular dementia, although particular dementia subtypes do not appear to be significantly associated with dehydration compared to patients with normal cognition. Message: Dehydration is common not only in etiologic MND subtypes, but also in patients without dementia. Hydration status should be evaluated in older adults irrespective of neurocognitive status. Some comorbidities, dysphagia and severity of cognitive dysfunction may increase the risk of dehydration in patients with dementia. Purpose: Studies investigating associations between etiologic subtypes of major neurocognitive disorder (MND) and dehydration frequency are lacking. The aim of this study was to investigate the prevalence and risk factors of dehydration among older adults with and without MND (dementia), and across different etiologic subtypes of MND. Methods: This cross-sectional study included adults aged ≥ 65 years old from one geriatric outpatient clinic. Dehydration was defined as a calculated [1,86 × (Na + K) + 1,15 × glucose + urea + 14] plasma osmolarity of > 295 mOsm/L.Clinical characteristics and measures of comprehensive geriatric assessments of patients with dehydration and normohydration were compared. MND was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders—Fifth Edition criteria. The underlying etiologic subtypes were determined by specific diagnostic criteria. Results: Of the 1377 patients 72% were female, the mean age was 80 ± 8 years, and 575 had dementia. Dehydration was more common in patients with dementia than those without dementia (58% vs. 53%, p = 0.044). The prevelance of dehydration was 57%, 62%, 54%, 57% and 68% in Alzheimer's disease, Parkinson's disease dementia, fronto-temporal dementia, dementia with Lewy bodies, and vascular dementia, respectively (p ≥ 0.05). MND was associated with dehydration (OR 1.26, 95% CI 1.01–1.57; p = 0.037) after adjustment for age and sex. In multivariable analysis, among patients with dementia, hypertension, DM, CKD, and dysphagia were more common while mean Mini-Mental State Examination score was lower in those who had dehydration versus no dehydration in older patients with dementia (p < 0.05). Conclusion: Dehydration is slightly associated with the presence of MND independent of age and sex. However, dehydration is also quite common in older patients without cognitive disorders. Therefore, hydration status should be monitored in older adults irrespective of neurocognitive status. Hypertension, DM, CKD, dysphagia and severity of cognitive dysfunction were associated with dehydration in patients with dementia. The prevalence of dehydration is highest in patients with vascular dementia. [ABSTRACT FROM AUTHOR]

Understanding the risks in the months following hospital discharge is crucial for healthcare professionals to ensure the need for assistance is met. However, this may be challenging in the case of patients living with a major neurocognitive disorder (PLMNCD). Thus, it is important to incorporate patients' and caregivers' experiences of the transition from hospital to home in the risk assessment. This multiple case study comprised 7 PLMNCD, their caregivers, and occupational therapists. Fifty-four interviews, conducted just before, as well as 3 weeks and 3 to 6 months after hospital discharge, were qualitatively analyzed. Results revealed that risk management during the hospital-to-home transition is a dynamic process aimed at establishing a satisfactory routine while avoiding adverse events. This risk management process, which identifies challenges over time and between stakeholders, involves (a) determining the seriousness and acceptability of risks, (b) reflecting on ways to manage risks, and (c) taking steps to manage risks. This knowledge will help to provide more appropriate care and services that strike a balance between safety and autonomy. [ABSTRACT FROM AUTHOR]

Background and Objectives This study examined the performance of the Modified Caregiver Strain Index (MCSI) in a sample of Black and White caregivers of persons living with dementia. Research Design and Methods Data on 153 dyads enrolled in the Care Ecosystem dementia care management program were analyzed, including sociodemographic variables, dementia severity, and caregiver burden and wellbeing. Factor structure, item-response patterns, and concurrent validity were assessed across racial groups. Results Differences between Black and White caregivers included gender, dyad relation, and socioeconomic disadvantage. Factor structure and item loadings varied by racial cohort, with parameters supporting a 3-factor model. For Black caregivers, finances and work, emotional and physical strain, and family and personal adjustment items loaded together on individual factors. For White caregivers physical and emotional strain items loaded on separate factors, although personal and family adjustment items loaded with work and financial strain items. Item-level analysis revealed differences between groups, with Black caregivers endorsing physical strain to a greater degree (p  = .003). Total MCSI scores were positively correlated with concurrent measures like the PHQ-9 (White: r  = 0.67, Black: r  = 0.54) and the GAD-2 (White: r  = 0.47, Black: r  = 0.4), and negatively correlated with self-efficacy ratings (White: r  = −0.54, Black: r  = −0.55), with a p  < .001 for all validity analysis. Discussion and Implications The MCSI displayed acceptable statistical performance for Black and White caregivers of persons living with dementia and displayed a factor structure sensitive to cultural variations of the construct. Researchers results highlight the inherent complexity and the relevance of selecting inclusive measures to appropriately serve diverse populations. [ABSTRACT FROM AUTHOR]

Vaccination helps reduce the risk of coronavirus disease 2019 (COVID-19) infection in elderly individuals with major neurocognitive disorders (MNDs). However, some caregivers are hesitant to have their elderly family members with MNDs vaccinated against COVID-19. This study explored the factors influencing caregivers' intentions to vaccinate elderly family members with MNDs against COVID-19. A total of 232 caregivers of elderly family members with MNDs participated in this study. In this survey, data regarding COVID-19 vaccination acceptance, fear, side effects, family members' attitudes toward vaccination, mental health status, neuropsychiatric symptoms, and cognitive impairments were collected from the elderly participants with MNDs. The associations between these variables and the caregivers' intention to vaccinate their elderly family members with MNDs against COVID-19 were examined using a multivariable linear regression analysis model. The results revealed that caregivers' perceived familial support for vaccination, the perceived value of vaccination, and autonomy to vaccinate elder family members were positively correlated with caregivers' intention to vaccinate elderly family members with MNDs, whereas elderly family members' age was negatively correlated with caregiver intentions. This study demonstrated that caregiver factors (perceived familial support, value of vaccination, and autonomy) and elderly family members' age were correlated with caregiver intention. These factors should be considered in developing interventions to enhance caregivers' intentions to vaccinate their elderly family members with MNDs against COVID-19. [ABSTRACT FROM AUTHOR]

BACKGROUND: In Latin America (LA), the prevalence of dementia is expected to triple to 150 million people by 2050. The 2020 Lancet Commission report identified several modifiable dementia risk factors, yet few social and environmental factors, most relevant to vulnerable regions of LA, were highlighted in this report. We sought to assess the epidemiology of neurocognitive disorders (NCD) in Puente Piedra, one of the most socially and economically vulnerable districts of Lima, the capital of Peru. METHODOLOGY: This was a cross-sectional door-to-door observational study that used two-stage household sampling. One young adult (30-59 years) and one older adult (>60 years) per household were enrolled. We collected demographic, clinical, and neurocognitive data. Addenbrookes Cognitive Examination (young adults) and the RUDAS-PE (older adults) were used, classifying participants as cognitively normal, possible mild NCD, or possible major NCD. RESULTS: We enrolled 247 participants (median age 46 years; 67% female). One-fourth had not completed secondary school and more than 50% completed only secondary school. Most participants were housewives (46%) and 21% did not have health insurance. The overall prevalence of possible NCD was 30% (25.6 and 41.8% among younger adults and older adults, respectively). Among younger adults, those ages 55-59 years more frequently had NCD (70%) compared to younger age ranges. Among older adults, only 3 subjects (4.5%) had major NCD. CONCLUSION: We found a high frequency of possible NCDs in a socially and economically vulnerable community in Lima, Peru, with younger adults showing levels of NCD higher than expected. Our findings support the need for health systems to incorporate cognitive screenings programs for NCD in younger ages. Future research on NCD would include younger populations, particularly in vulnerable communities.

AbstractObjective: Neuroendocrine tumors (NETs) are neoplasms that primarily occur in the lungs, appendix, small intestine, pancreas, and rectum, and typically metastasize to the liver or lymph nodes. However, in rare cases NETs can originate in the central nervous system (CNS). Understanding primary CNS NET neuropsychological manifestations aids in recommendations for neurocognitive follow-up, treatment and lifestyle planning, and future research. Method: Given the dearth of neuropsychological research for CNS NETs, we present a case seen in a 43-year-old woman. Results: Initial and 8-month follow-up neuropsychological evaluations of the patient revealed a Major Neurocognitive Disorder where the pattern of findings was consistent with tumor location and additional treatment-related factors. Reliable change indices at her re-evaluation revealed declines in verbal and visual memory, with statistical, yet not clinical, improvements in different domains. Follow-up monitoring of comprehensive care continued to occur after neuropsychological evaluations. Conclusions: This case study assists in the characterization of initial and follow-up neuropsychological presentation of a primary CNS NET, where evaluations helped inform clinical care and functional recommendations. This case demonstrates the importance for neuropsychologists to have awareness of various conditions, even rare conditions, which can inform a systematic approach to research and clinical care with neuro-oncological populations.

Purpose: Independence in activities of daily living (ADLs) is associated with quality of life (QoL) in individuals with dementia. However, the contribution of physical and cognitive functions to this relationship needs further examination. This study aims to examine the mediating effect of physical fitness and cognitive function in the relationship between independence in basic ADLs and QoL among older adults with dementia. Methods: This cross-sectional study included 107 older adults with dementia (74.8% women; age 78.21 ± 7.70 years). Independence in basic ADL and QoL were evaluated using the Barthel Index (BI) and QoL- Alzheimer's Disease Scale, respectively. The Alzheimer's Disease Assessment Scale–Cognitive Subscale and the Mini-Mental State Examination were applied to assess cognitive function. Physical fitness was evaluated using the 30-s chair stand, 2-min step and the Timed-Up and Go tests. A structural equation modelling (SEM) with bootstrapping estimation was conducted to determine the relationship between all variables. Results: Independence in basic ADL positively affected QoL and this association was mediated by physical fitness (β = 0.242, p = 0.011). No statistically significant results were observed when testing cognitive function as a mediator between BI and QoL (β = 0.009, p = 0.345). Conclusions: Physical fitness (i.e., lower body strength, aerobic capacity, and mobility) plays a role in the relationship between basic ADL independence and QoL of older adults with dementia, reinforcing the need to improve and monitor these parameters throughout the disease progression. Future longitudinal studies should explore the temporal relationship between physical and cognitive function and its contribution to basic ADL independence and QoL. [ABSTRACT FROM AUTHOR]

Alzheimer’s disease is the most common type of dementia, producing a deterioration in the activities of daily living which can lead to the need for care provision. COVID-19 impacted their quality of life and in this care delivery. This study aimed to analyse most productive and prominent authors, the journals and countries with the highest number of publications, the most cited documents and the most used keywords. Publications were retrieved from journals indexed in the Main Collection of the Web of Science (WoS) and analysed using the traditional laws of bibliometrics. A total of 376 documents were found. The WoS categories with the highest number of publications accumulated were “Geriatric Gerontology” and “Gerontology.” Clarissa Giebel was the most productive (23 papers) and most cited (with 569 citations) co-author. The Journal of Alzheimer’s Disease (21 papers) published the most number of documents. The manuscript “2021 Alzheimer’s Disease Facts and Figures” was the most cited. Four thematic clusters related to mental health, telemedicine, care and well-being were found among the authors’ keywords. Research networks exist worldwide, with the United States of America and England leading the scientific output. These results may be of interest to researchers, publishers and professionals interested in this subject, as they provide current information on publications related to this topic.

Background: Physical activity (PA) is a promising non-pharmacological intervention for this population. However, few studies have investigated their PA trajectories, influencing factors, and their relationship with health outcomes. Aims: The aim was to identify latent trajectories in PA and their determinants in older adults with mild cognitive impairment (MCI) or dementia, as well as to assess the associations between PA trajectories and health outcomes based on the capability-opportunity-motivation behavior model. Methods: This is a cohort study. Data were obtained from a national cohort study and included participants aged 60 years and older with MCI or dementia. PA trajectories were identified using group-based trajectory modelling. Multinomial logistic regression was conducted to identify the predictors of PA trajectories. Linear regression models were used to assess the associations between PA trajectories and health outcomes. This study adhered to the STROBE checklist for reporting. Results: Three distinct PA trajectories were identified: high-decreasing and rebound class (9.34%), moderate-decreasing class (10.31%), and low-increasing class (80.34%). The logistic regression showed that age, sex, education level, body mass index, residence, depressive symptoms, mobility activities of daily life score, frequency of social activities score were PA predictors. Adjusting for sociodemographic variables, only the high-decreasing and rebound class remained significantly associated with worse self-rated health. Discussion: This study revealed three PA trajectories among older adults with MCI/dementia. Besides sociodemographic variables, addressing physical function and mental health, providing social support are vital for promoting PA in this population. [ABSTRACT FROM AUTHOR]

Mild cognitive impairment (MCI) is defined as inter-stage between normal cognitive aging and major neurocognitive disorder (MND). This state of decay is a crucial factor in treatment to prevent the progression to MND. In this study, our group developed a virtual screening process to evaluate 2568 phytochemical compounds against 5 key proteins associated with MCI and MND. As a result, two potential candidates were identified: carpaine, found in Carica papaya leaves, and punicalagin, present in Punica granatum. A model of cognitive impairment (CI) was developed in 10-month-old male Sprague Dawley rats by administering aluminum chloride (AlCl3) at a dose of 100 mg/kg/day for 30 days. After AlCl3 administration period, one of the groups received carpaine and punicalagin in a phytochemical extract (PE) by oral gavage for 30 days. Novel object recognition test (NOR) was assessed at three different time points (T1 — before CI, T2 — after CI, and T3 — after PE treatment). Glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL) were identified in the hippocampus of rats at the end of the study period. After administration of AlCl3, a reduction in discrimination index vs control rats (CI = 0.012 ± 0.08 vs Control = 0.076 ± 0.03), was observed. After phytochemical extract treatment, a significant increase in discrimination index values was observed in the PE group 0.4643 ± 0.13 vs CI group 0.012 ± 0.08. Additionally, the evaluation of immunohistochemistry showed an increase in GFAP positivity in the hippocampus of the CI groups, while a slight decrease was observed in the PE group. This work addressed a comprehensive methodology that utilized in silico tools to identify phytochemical compounds (carpaine and punicalagin) as potential candidates for affecting key proteins in CI. The phytochemical extract containing carpaine and punicalagin resulted in a trend in the decrease of GFAP expression in the hippocampus and improved recognition memory in rats with CI induced by age and AlCl3 administration.

• What is the primary question addressed by this study? Available pharmacological treatments for frontotemporal dementia (FTD) might be supported based on small-scale randomized controlled trials; however, the clinical recommendation might not be conclusive. • What is the main finding of this study? High-dose oxytocin (72 international units) was associated with the greatest improvement in patients' neuropsychiatric symptoms and daily interactive activities. Piracetam should be avoided, as it could greatly exacerbate neuropsychiatric symptoms and increase a caregiver's stress. • What is the meaning of the finding? This study provides the first clinical proof-of-concept network meta-analysis using current evidence on pharmacotherapy in patients with FTD and supports the potential beneficial effects of high doses of oxytocin on neuropsychiatric symptoms. The neuropsychiatric symptoms of frontotemporal dementia (FTD) have a profound negative impact on disease outcomes and care burden. Available pharmacotherapies might be supported by small-scale randomized controlled trials (RCTs); however, clinical recommendations might not be conclusive. We systematically searched several databases from inception to April 30, 2022, for RCTs of drug therapy in patients with FTD and neuropsychiatric symptoms (primary outcome). Secondary outcomes included changes in caregiver stress, daily interactive activities, cognitive function, and acceptability (adverse event or dropout rates). The network meta-analysis (NMA) procedure was performed under the frequency model, showing effect sizes as standardized mean differences (SMD) or odds ratios (OR) with 95% confidence intervals (95% CIs). Seven RCTs with 243 participants were included. Compared with placebo, high-dose oxytocin (72 international units) was associated with the greatest improvement in patients' neuropsychiatric symptoms (SMD = −1.17, 95% CIs = −2.25 to −0.08, z = −2.10, p = 0.035). Piracetam significantly worsened neuropsychiatric symptoms (SMD = 3.48, 95% CIs = 1.58 to 5.37, z = 3.60, p < 0.001) and caregiver stress (SMD = 2.40, 95% CIs = 0.80–4.01, z = 2.94, p = 0.003). Trazodone had significantly higher rates of adverse events (OR = 9.53, 95% CIs = 1.85–49.20, z = 2.69, p = 0.007). No pharmacological intervention significantly benefited cognitive function. This study provides the first NMA for clinical recommendation to support the use of high-dose oxytocin and caution regarding the use of piracetam for neuropsychiatric symptoms in patients with FTD.

ABSTRACT BACKGROUND: The Positive Aspects of Caregiving (PAC) scale is used to assess psychosocial benefits provided to caregivers by the task of caring. The PAC scale consists of nine items, assessed using a five-point Likert scale, with higher values indicating greater positive perceptions and gains from the caregiving experience. OBJECTIVE: To translate and culturally adapt the PAC scale for informal Brazilian caregivers of people with dementia. DESIGN AND SETTING: A methodological study was conducted at the Federal University of São Carlos. METHODS: The following stages were carried out: Translation; Synthesis of the translations; Back-translation; Evaluation by an experts’ committee; and Pre-test. RESULTS: Two independent professionals translated the PAC scale. The consensus version was obtained by merging both translations, which were back-translated into English by a third translator. The expert committee comprised three specialists in the area and project researchers. All scale items presented a Content Validity Index of 1 (CVI = 1.0), and thus remained in the pre-final version of the instrument. The instrument was pre-tested with seven caregivers of people with dementia, the majority of whom were women (57.1%), with a degree of kinship corresponding to sons/daughters (57.1%) and an average age of 55.2 (± 4.1) years. The caregivers considered it clear and understandable and made no suggestions for changes. CONCLUSION: The PAC scale was translated and culturally adapted for use by informal caregivers of people with dementia in Brazil. However, a psychometric analysis of the instrument is necessary to provide normative data for this population group.

Vaccination helps reduce the risk of coronavirus disease 2019 (COVID-19) infection in elderly individuals with major neurocognitive disorders (MNDs). However, some caregivers are hesitant to have their elderly family members with MNDs vaccinated against COVID-19. This study explored the factors influencing caregivers’ intentions to vaccinate elderly family members with MNDs against COVID-19. A total of 232 caregivers of elderly family members with MNDs participated in this study. In this survey, data regarding COVID-19 vaccination acceptance, fear, side effects, family members’ attitudes toward vaccination, mental health status, neuropsychiatric symptoms, and cognitive impairments were collected from the elderly participants with MNDs. The associations between these variables and the caregivers’ intention to vaccinate their elderly family members with MNDs against COVID-19 were examined using a multivariable linear regression analysis model. The results revealed that caregivers’ perceived familial support for vaccination, the perceived value of vaccination, and autonomy to vaccinate elder family members were positively correlated with caregivers’ intention to vaccinate elderly family members with MNDs, whereas elderly family members’ age was negatively correlated with caregiver intentions. This study demonstrated that caregiver factors (perceived familial support, value of vaccination, and autonomy) and elderly family members’ age were correlated with caregiver intention. These factors should be considered in developing interventions to enhance caregivers’ intentions to vaccinate their elderly family members with MNDs against COVID-19.

Introduction: Psychotropic drugs are utilized against neuropsychiatric symptoms among people with major neurocognitive disorder (NCD) despite well‐documented risks, and older people in nursing homes are expected to be more frequently exposed to those medicines. This study compared psychotropic drug use and associated factors between older people with major NCD and matched references. Methods: This cross‐sectional study included individuals from three national registries in Sweden. References were randomly matched 1:1 by age and sex from the Swedish Total Population Register. Drug use was defined as at least one prescription fill from 1 July to 31 December 2019 and presented as proportion of drug users. In addition, ORs regarding psychotropic drug use and associated factors use were analysed using generalized estimating equations. Results: There were 102,419 complete matching pairs alive on 31 December 2019. The proportions of psychotropic drug users were 59% in the population of people with major NCD and 28% in the reference group. Moreover, there was a substantial number of individuals in nursing homes who had been treated with antipsychotics but who, for unknown reasons, had not been diagnosed with major NCD. Psychotropic drug use was positively associated with both major NCD and nursing home residency. The difference in drug use in relation to major NCD was more pronounced among people living in ordinary homes. Conclusion: Despite well‐documented risks in people with cognitive impairment, psychotropic drug use was overall high and positively associated with both major NCD and nursing home residency. Taken together, interventions to better target neuropsychiatric symptoms in older people are warranted. Hypnotic drug use among older people in general as well as antipsychotic drug exposure among older people in nursing homes appear to be two important focus areas. Key points: Psychotropic drug use was positively associated with both major neurocognitive disorder (NCD) and nursing home residencyThe association between major NCD and psychotropic use was more pronounced among people in ordinary homesMore than one in 10 nursing home residents in the reference group used antipsychotics [ABSTRACT FROM AUTHOR]

Psychosis is common among individuals with neurocognitive disorders, is difficult to manage, and causes considerable burden and stress to patients and caregivers. Developing effective treatments is a substantial unmet medical need but research has been slowed by the need for updated consensus diagnostic criteria. To address this need, the International Psychogeriatrics Association initiated a process to develop criteria for clinical use, research, and treatment development efforts. The process included clinical, regulatory, and industry stakeholders as well as input from a global network of experts in geriatric psychiatry responding to two surveys (N = 336). Results from the consensus process confirmed that clinicians wanted elaboration of aspects of the definition proposed by Jeste and Finkel in 2000 to ensure that the criteria are applied appropriately. Based on discussions, the survey, and emerging research, criteria were revised to apply to psychosis occurring with all major and mild neurocognitive disorders. Other important changes include providing examples of hallucinations and delusions and clarifying time course, impact, and exclusionary criteria. This definition of psychosis in major and mild neurocognitive disorders can be used to advance many types of research including development of much needed pharmacologic and nonpharmacologic interventions for psychosis in patients with neurocognitive disorders.

Summary: Despite evidence suggesting that insomnia is associated with the risk of dementia and cognitive dysfunction, studies have shown mixed results. Dementia has a long prodromal phase, and studies with long follow‐up are required to avoid reverse causality. In our 11‐year follow‐up study, we assessed whether probable insomnia disorder (PID) based on diagnostic criteria, and insomnia symptoms were associated with risk of all‐cause dementia, Alzheimer's disease (AD) and cognition, measured with the Montreal Cognitive Assessment scale. We also examined if Apolipoprotein E genotype modified any associations with dementia through interaction. We analysed data from 7492 participants in the Norwegian Trøndelag Health Study. PID was not associated with all‐cause dementia (odds ratio = 1.03, 95% confidence interval = 0.74–1.43), AD (odds ratio = 1.07, 95% confidence interval = 0.71–1.60) or Montreal Cognitive Assessment score (regression coefficient = 0.37, 95% confidence interval = −0.06 to 0.80). The insomnia symptom "difficulties maintaining sleep" was associated with a lower risk of all‐cause dementia (odds ratio = 0.81, 95% confidence interval = 0.67–0.98), AD (odds ratio = 0.73, 95% confidence interval = 0.57–0.93), and better Montreal Cognitive Assessment score, mean 0.40 units (95% confidence interval = 0.15–0.64). No interaction with Apolipoprotein E genotype was found. PID and insomnia symptoms did not increase the risk of dementia in our study. More research with longer follow‐up is needed, and future studies should explore if the associations to dementia risk vary across insomnia subtypes. [ABSTRACT FROM AUTHOR]

Introduction: Depression is often difficult to detect in long-term care (LTC) patients with major neurocognitive disorders (MNCD), and an observer-rated screening scale could facilitate assessments. This study aimed to establish the external validity and reliability of the Nursing Homes Short Depression Inventory (NH-SDI) in LTC patients with MNCD and to compare its estimates to the Cornell Scale for Depression in Dementia (CSDD), the most used scale for depression in MNCD. Methods: A focus discussion group of experts assessed the content validity of the NH-SDI. Then, a convenience sample of 93 LTC patients with MNCD was observer-rated by trained nurses with the NH-SDI and CSDD. For 57 patients, a medical assessment of depression was obtained, and screening accuracy estimates were generated. Results: The prevalence of depression was 8.8% as per reference standard. NH-SDI's content validity was judged acceptable with minor item wording modifications and specifications. The NH-SDI (cut-off ≥3) achieved 100% (95% confidence interval [CI]: 46–100%) sensitivity, 83% (95% CI: 69–91%) specificity, and 36% (95% CI: 14–64%) positive predictive value (PPV). The CSDD (cut-off ≥3) achieved 100% (95% CI: 46–100%) sensitivity, 75% (95% CI: 61–86%) specificity, and 28% (95% CI: 11–54%) PPV. No significant differences in areas under the receiver operating characteristic curve were found between scales. The NH-SDI and CSDD were highly correlated (rs = 0.913; p < 0.001) and reliable (ICC = 0.77; p < 0.001). Conclusion: The NH-SDI appears valid and reliable in LTC patients with MNCD and quicker than the CSDD to rule out depression in a busy or short-staffed setting. [ABSTRACT FROM AUTHOR]

Introduction: Prior estimates of dementia prevalence in India were based on samples from selected communities, inadequately representing the national and state populations. Methods: From the Longitudinal Aging Study in India (LASI) we recruited a sample of adults ages 60+ and administered a rich battery of neuropsychological tests and an informant interview in 2018 through 2020. We obtained a clinical consensus rating of dementia status for a subsample (N = 2528), fitted a logistic model for dementia status on this subsample, and then imputed dementia status for all other LASI respondents aged 60+ (N = 28,949). Results: The estimated dementia prevalence for adults ages 60+ in India is 7.4%, with significant age and education gradients, sex and urban/rural differences, and cross‐state variation. Discussion: An estimated 8.8 million Indians older than 60 years have dementia. The burden of dementia cases is unevenly distributed across states and subpopulations and may therefore require different levels of local planning and support. Highlights: The estimated dementia prevalence for adults ages 60+ in India is 7.4%.About 8.8 million Indians older than 60 years live with dementia.Dementia is more prevalent among females than males and in rural than urban areas.Significant cross‐state variation exists in dementia prevalence.

The use of potentially inappropriate medications (PIMs) is a problem since it might contribute significantly to adverse drug reactions and hospital admissions among elderly with major neurocognitive disorder (NCD). To assess the appropriateness of drug treatment, different explicit criteria have been developed. To investigate and compare the prevalence of PIM users among elderly with major NCD on a nationwide basis using 3 different explicit criteria. Furthermore, the study aimed to investigate factors associated with the use of PIMs. This nationwide register-based study included 35,212 people, 65 years or older, diagnosed with major NCD and registered in the Swedish registry for cognitive/dementia disorders up to June 30, 2017 and alive December 31, 2017. PIMs were identified using 3 different explicit criteria; the Swedish quality indicators, the EU(7)-PIM list and the AGS Beers Criteria. PIM use was defined as having collected a minimum of one PIM at least once between July 01 – December 31, 2017. The numbers of people using one or more PIMs were 7629 (21.7%) according to the Swedish quality indicators, 11,838 (33.6%) according to the EU(7)-PIM list, and 12,002 (34.1%) according to AGS Beers Criteria. Antipsychotics, antithrombotic agents and anxiolytics were the most frequently used PIM class according to the different assessment tools, respectively. The use of PIMs was positively associated with vascular dementia and Lewy body dementia/Parkinson's disease dementia, regardless of the assessment tool used. However, the association between using at least one PIM and age, sex, MMT-value and frontotemporal dementia, differed depending on the criteria used. The different results and included PIMs indicate the different perspectives on PIMs between criteria, which make it difficult to compare the results. However, psychotropic drug use requires further highlighting, as well as the association between PIM use and different types of major NCD. [ABSTRACT FROM AUTHOR]

Introduction: Etiological diagnosis of neurocognitive disorders of middle‐old age relies on biomarkers, although evidence for their rational use is incomplete. A European task force is defining a diagnostic workflow where expert experience fills evidence gaps for biomarker validity and prioritization. We report methodology and preliminary results. Methods: Using a Delphi consensus method supported by a systematic literature review, 22 delegates from 11 relevant scientific societies defined workflow assumptions. Results: We extracted diagnostic accuracy figures from literature on the use of biomarkers in the diagnosis of main forms of neurocognitive disorders. Supported by this evidence, panelists defined clinical setting (specialist outpatient service), application stage (MCI‐mild dementia), and detailed pre‐assessment screening (clinical‐neuropsychological evaluations, brain imaging, and blood tests). Discussion: The Delphi consensus on these assumptions set the stage for the development of the first pan‐European workflow for biomarkers' use in the etiological diagnosis of middle‐old age neurocognitive disorders at MCI‐mild dementia stages. Highlights: Rational use of biomarkers in neurocognitive disorders lacks consensus in Europe.A consensus of experts will define a workflow for the rational use of biomarkers.The diagnostic workflow will be patient‐centered and based on clinical presentation.The workflow will be updated as new evidence accrues.

This paper examines the prevalence of different types of elder mistreatment, care needs, and risk factors amongst older adults living with and without dementia in any setting (community or institution). Three years (2014–2017) of anonymized reported incidents of elder mistreatment to a national UK helpline were examined in an exploratory study, using a matched sample design (N = 598) comparing adults with dementia (n = 299) to those without (n = 299) on mistreatment type, care needs, and risk factors for abuse. Financial exploitation was more common among older adults with dementia who required more daily care than those without. Risk factors for elder mistreatment among older adults without dementia were often chronic in nature (such as poor physical health) whereas risk factors for people with dementia were associated with a dementia diagnosis. Raising implications for health and social care, results show that older adults diagnosed with dementia had increased care needs and vulnerability to abuse. [ABSTRACT FROM AUTHOR]

The article discusses the ethical considerations of using neuromodulation, specifically spinal cord stimulation (SCS), in adults with cognitive impairment and chronic pain. It highlights the challenges and opportunities for pain management in this population. It addresses issues such as stigma associated with both conditions, underrecognition of cognitive impairment, assessment of treatment outcomes, decision-making capacity, and the well-being of care partners.

Introduction: Depression is often under-detected in long-term care (LTC) patients with major neurocognitive disorders (MNCD) and is associated with important morbidity, mortality, and costs. Observer-rated outcome measures (ObsROMs) could help resolve this problematic; however, evidence on their accuracy is scattered in the literature. This systematic review aimed at summarizing this evidence. Methods: A literature search was conducted in 7 databases using keywords, MeSHs, and bibliographic searches. We included studies published before January 2022 and reporting on the accuracy of a depression ObsROM used in LTC patients with MNCD. Data extraction, analysis, synthesis, and study methodological quality assessments were done by two authors, and discrepancies were resolved by consensus. Results: Among 9,660 articles retrieved, 8 studies reporting on 11 depression measures were included. Scales were classified as patient-reported outcome measures used as Obs-ROMs or true ObsROMs. Among the first category, the Cornell Scale for Depression in Dementia (CSDD) and the Montgomery-Asberg Depression Rating Scale (MADRS) performed best (area under the curve [AUC]: 0.73–0.87), although both presented with low positive predictive values and high negative predictive values. Among the second category, the Nursing Homes Short Depression Inventory (NH-SDI) performed best, with an AUC of 0.93 and ≥85% sensitivity, specificity, and predictive values. Conclusion: The CSDD and MADRS may be useful to rule out depression in LTC patients with MNCD, whereas the NH-SDI may be useful to rule in and out depression within this same population. Before recommending their use, adequately powered studies to further examine their accuracy in different contexts are necessary. [ABSTRACT FROM AUTHOR]

Introduction: Blood‐based biomarkers are the next challenge for Alzheimer's disease (AD) diagnosis and prognosis. Methods: Mild cognitive impairment (MCI) participants (N = 485) of the BALTAZAR study, a large‐scale longitudinal multicenter cohort, were followed‐up for 3 years. A total of 165 of them converted to dementia (95% AD). Associations of conversion and plasma amyloid beta (Aβ)1‐42, Aβ1‐40, Aβ1‐42/Aβ1‐40 ratio were analyzed with logistic and Cox models. Results: Converters to dementia had lower level of plasma Aβ1‐42 (37.1 pg/mL [12.5] vs. 39.2 [11.1] , P value =.03) and lower Aβ1‐42/Aβ1‐40 ratio than non‐converters (0.148 [0.125] vs. 0.154 [0.076], P value =.02). MCI participants in the highest quartile of Aβ1‐42/Aβ1‐40 ratio (>0.169) had a significant lower risk of conversion (hazard ratio adjusted for age, sex, education, apolipoprotein E ε4, hippocampus atrophy = 0.52 (95% confidence interval [0.31–0.86], P value =.01). Discussion: In this large cohort of MCI subjects we identified a threshold for plasma Aβ1‐42/Aβ1‐40 ratio that may detect patients with a low risk of conversion to dementia within 3 years.
