Four weeks of placebo stimulation was followed by 8 weeks of active ultrasonic stimulation and a 4-week follow-up. Primary endpoints were the effects of ultrasonic head stimulation on both cognitive dysfunction and behavioral and psychological symptoms of dementia (BPSD). Cognitive dysfunction was evaluated using the Japanese versions of the Mini-Mental State Examination and Montreal Cognitive Assessment, and BPSD was assessed using the Neuropsychiatric Inventory Brief Questionnaire Form. For cognitive fluctuations, the Cognitive Fluctuation Inventory served as an index. Improvements in parkinsonism, activities of daily living, and caregiver burden were examined as secondary endpoints.Results: Twelve patients were enrolled. The primary endpoint was significantly improved during the active stimulation period, as were secondary endpoint ratings for parkinsonism and caregiver burden.

Identifying the characteristics of delusions and hallucinations in the AD population is key to understanding the interconnection between the psychiatric and cognitive symptoms in neurocognitive disorders. The aim of this study is to compare the cognitive profiles of AD patients with and without psychosis.Methods: We conducted a rapid review to explore the relationship between psychotic symptoms and cognitive performances in patients with AD. We used MEDLINE, Embase, and PsychINFO literature databases between January 2015 and January 2023. This rapid review was guided by the Cochrane Rapid Reviews Methods Group.Results: We identified 2909 records from the initial searches. After reviewing the titles, abstracts, and full texts, we selected 8 cross-sectional and 5 cohort studies for the qualitative analysis. Among them, 6 studies were included in the final quantitative analysis. Most studies suggested a correlation between general cognitive decline and the risk of presenting psychotic symptoms. Three studies found an association between hallucinations and deficits in the visuocognitive domains (visuospatial, visuoperceptual, and visuoconstructive skills). Two studies found a relationship between psychotic symptoms and executive dysfunction. Two studies also found a correlation between psychotic symptoms and language. Our results are in line with previous data in the literature, especially regarding the outcome of psychosis on executive function and visuocognitive abilities.Conclusions: There appears to be an association between cognitive deficits and psychotic symptoms in AD, but the direction of causality is still unclear, and further studies using longitudinal designs would give more insight into the pathophysiological process of psychosis in AD.","PeriodicalId":7679,"journal":{"name":"Alzheimer Disease & Associated Disorders","volume":" ","pages":"369-376"},"PeriodicalIF":1.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142339435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a much higher prevalence (10.6%) than in healthy North African subjects (1.45%) but lower than in North African patients with Parkinson disease (36% to 39%). Carriers tended to develop more often orthostatic hypotension and swallowing problems.Conclusions: Where previous studies in European and North American patients found no link between LRRK2 mutations and LBD, we found an LRRK2 mutation associated with Lewy body disease, namely the G2019S mutation that might be restricted to patients with North African ancestors. Our study illustrates the need to introduce ethnic diversity as stratifying factor in the analysis of genetic causes of neurodegenerative disorders. The current development of disease-modifying drugs modulating LRRK2 kinase activity could justify to screen North African patients with LBD for the G2019S LRRK2 mutation.","PeriodicalId":7679,"journal":{"name":"Alzheimer Disease & Associated Disorders","volume":"38 4","pages":"328-331"},"PeriodicalIF":1.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142715164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To provide comparison between Singapore and US samples, a US sample with similar profile was retrieved from the National Alzheimer Coordinating Center (NACC) database.Patients: Scores were compared with 1853 participants with similar profile from the United States. Score-difference between the populations was computed using multiple linear regression (adjusted for covariates), with equivalent score considered present when 90% CI of the score-difference fell within the predefined margin of equivalence.Results: Tasks assessing for memory, processing speed, and executive functioning showed equivalence in scores between US and Singapore samples (adjusted-score difference=-0.94 to 0.09). Singapore sample performed marginally better on the visuospatial task (adjusted-score difference=0.50), but poorer on the language task (adjusted-score difference=-3.22).Discussion: Nonequivalence of visuospatial and language tasks, which may increase potential misinterpretation of cognitive profiles and misdiagnosis, are related to educational and cultural differences.

Each participant and their caregivers completed the socioemotional questionnaire (SEQ); a 30-item rating scale assessing five dimensions of socioemotional cognition (empathy, emotion recognition, social conformity, antisocial behavior, sociability). We evaluated global cognition, awareness of disease, dementia severity, functionality, neuropsychiatric symptoms, and caregiver burden.Results: Participants in the mild and moderate groups showed a similar pattern of socioemotional self-perception. They differed in the anger domain of the emotion recognition subscale, in the antisocial behavior dimension, and in the sociability subscale. In contrast, the caregivers' perspective of people with mild and moderate AD showed a significant difference in the emotion recognition domain for fear, disgust, and sadness. There were also significant differences in the empathy subscale for disgust and in the sociability subscale. Cognition was correlated with self-reported reduced perception in social conformity, antisocial behavior, and sociability. Awareness was correlated with emotion recognition, antisocial behavior, and sociability. Neuropsychiatric symptoms were correlated with empathy, emotion recognition, and social conformity.Conclusions: Significant differences were found between caregivers' perspectives of socioemotional functioning in people with mild and moderate AD.
