Risk Management During the Transition From Hospital to Home: A Multiple Case Study Documenting the Experience of Patients Living With a Major Neurocognitive Disorder, Their Caregivers, and Healthcare Professionals.

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.

Multicenter, Open-Label, Prospective Study Shows Safety and Therapeutic Benefits of a Defined Ginkgo Biloba Extract for Adults with Major Neurocognitive Disorder.

INTRODUCTION: The safety and therapeutic effects of Gingko biloba extract EGb 761® to treat cognitive decline have been demonstrated in numerous clinical trials. However, trials in Indian populations have been lacking. METHODS: This open-label, multicenter, single-arm, phase IV trial enrolled 150 patients aged ≥50 years with major neurocognitive disorder due to Alzheimer's disease, major vascular neurocognitive disorder, or mixed forms of both according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria and a Mini-Mental State Examination (MMSE) score of 12-24. Patients took 120 mg EGb 761® twice daily for 18 weeks. Therapeutic effects were assessed by CERAD constructional praxis and recall of constructional praxis (CERAD CP, CERAD recall of CP), Trail-Making Test (TMT), Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), Clinical Global Impressions (CGI) scale, and 11-point box scales for tinnitus and vertigo. Safety assessment was based on the occurrence of adverse events as well as changes in clinical, laboratory, and functional parameters. RESULTS: After 18 weeks, significant improvements compared to baseline were found in constructional praxis (CERAD CP, p < 0.0001), memory (CERAD recall of CP, p < 0.0001), speed and executive functioning (TMT A, p < 0.0001; TMT B, p < 0.0001), and behavioral symptoms (BEHAVE-AD, p < 0.0001). Forty-five adverse events were reported in 33 (22.0%) patients in total, including ten presumed adverse drug reactions in 9 (6.0%) patients. Headache and diarrhea of mild-to-moderate severity were the most frequent events. Two serious adverse events, both considered unrelated to the study drug, occurred in 2 (1.3%) patients. CONCLUSION: This study confirmed the favorable safety profile and suggested therapeutic benefits of EGb 761® in Indian patients with major neurocognitive disorder.

Global trends in dementia care research in the context of COVID-19: bibliometric analysis.

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.

Factors Related to Caregivers' Intention to Vaccinate Their Elderly Family Members with Major Neurocognitive Disorders against COVID-19.

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.

A neuropsychological profile for high-grade primary central nervous system neuroendocrine tumor (CNS NET): a single-case study.

Objective: 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.

The relationship between dehydration and etiologic subtypes of major neurocognitive disorder in older patients.

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.

Performance of the Modified Caregiver Strain Index in a Sample of Black and White Persons Living With Dementia and Their Caregivers.

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.

Physical activity trajectories and their associations with health outcomes in older adults with mild cognitive impairment or dementia: a national cohort study.

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.

Phytochemical Extract from Carica papaya Leaves and Punica granatum Seeds as Therapy Against Cognitive Impairment in a Murine Model.

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.

Do physical fitness and cognitive function mediate the relationship between basic activities of daily living and quality of life in older adults with dementia?

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 (ß = 0.242, p = 0.011). No statistically significant results were observed when testing cognitive function as a mediator between BI and QoL (ß = 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.

Translation and cultural adaptation of the Positive Aspects of Caregiving Scale for caregivers of people living with dementia in Brazilian context: a methodological study

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.

The German version of the tablet-based UCSF Brain Health Assessment is sensitive to early symptoms of neurodegenerative disorders.

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 (Alzheimer's 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.

Epidemiology of neurocognitive disorders in adults from urban-marginalized areas: a door-to-door population-based study in Puente Piedra, Lima, Peru.

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. Addenbrooke's 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.

The impact of nursing home residency on psychotropic drug use in major neurocognitive disorder: A nationwide comparison.

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.

Effects of art therapy for people with mild or major neurocognitive disorders: A systematic review and meta-analysis.

OBJECTIVES: The aim of this study was to analyze the efficacy of non-pharmacological, interactive, and emotional art therapy interventions for patients with mild neurocognitive disorder (mild NCD) or major neurocognitive disorder (MNCD). METHODS: A systematic review and meta-analysis assessed English-language literature published from January 1, 2001, to August 22, 2021, and indexed in CINAHL, EMBASE, MEDLINE, PubMed, Web of Science, and PsycINFO. People with mild NCD or MNCD who received art therapy were classified as the intervention group. Study quality was assessed using the Risk of Bias (RoB) 2 and the Joanna Briggs Institute tool. RESULTS: Among nine included studies, depression was significantly reduced as compared with control groups (Cohen's d = -0.52 [95 % CI = -0.99-0.05], p < 0.001, I2 = 62.90 %) but not cognitive function or quality of life. CONCLUSION: People with mild neurocognitive disorder or MNCD are encouraged to engage in art therapy delivered by art therapists collaborating with healthcare providers. The effects of specific types of art therapy should be explored. PRACTICAL IMPLICATION: Healthcare providers should be encouraged to provide art therapy designed to reduce depression in patients with mild NCD or MNCD.

The External Validation of the Nursing Homes Short Depression Inventory in Older Adults with Major Neurocognitive Disorders in Long-Term Care Centers.

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.

Treatment Efficacy of Pharmacotherapies for Frontotemporal Dementia: A Network Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: 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. METHODS: 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). RESULTS: 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. CONCLUSIONS: 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.

Validation of the test for finding word retrieval deficits (WoFi) in detecting Alzheimer's disease in a naturalistic clinical setting.

BACKGROUND: Detecting impaired naming capacity contributes to the detection of mild (MildND) and major (MajorND) neurocognitive disorder due to Alzheimer's disease (AD). The Test for Finding Word retrieval deficits (WoFi) is a new, 50-item, auditory stimuli-based instrument. OBJECTIVE: The study aimed to adapt WoFi to the Greek language, to develop a short version of WoFi (WoFi-brief), to compare the item frequency and the utility of both instruments with the naming subtest of the widely used Addenbrooke's cognitive examination III (ACEIIINaming) in detecting MildND and MajorND due to AD. METHODS: This cross-sectional, validation study included 99 individuals without neurocognitive disorder, as well as 114 and 49 patients with MildND and MajorND due to AD, respectively. The analyses included categorical principal components analysis using Cramer's V, assessment of the frequency of test items based on corpora of television subtitles, comparison analyses, Kernel Fisher discriminant analysis models, proportional odds logistic regression (POLR) models and stratified repeated random subsampling used to recursive partitioning to training and validation set (70/30 ratio). RESULTS: WoFi and WoFi-brief, which consists of 16 items, have comparable item frequency and utility and outperform ACEIIINaming. According to the results of the discriminant analysis, the misclassification error was 30.9%, 33.6% and 42.4% for WoFi, WoFi-brief and ACEIIINaming, respectively. In the validation regression model including WoFi the mean misclassification error was 33%, while in those including WoFi-brief and ACEIIINaming it was 31% and 34%, respectively. CONCLUSIONS: WoFi and WoFi-brief are more effective in detecting MildND and MajorND due to AD than ACEIIINaming.
