Recent research has investigated oxytocin as a potential treatment for these symptoms; however, whether plasma oxytocin is associated with social-emotional symptoms of dementia remains underexplored. Methods: Thirty behavioral-variant FTD (bvFTD), 28 SD, 39 AD, and 24 controls underwent blood sampling to measure oxytocin. Participants completed an emotion processing battery. Carers completed the Cambridge Behavioral Inventory and the Neuropsychiatric Inventory. Results: Patients with bvFTD were severely impaired in emotion processing and behavioral ratings, with milder impairment in SD and AD. No difference in plasma oxytocin was observed between groups (p = 0.632). No significant associations were found between oxytocin and social behavior or emotion processing (r values between −0.241 and 0.227, all p values >0.099). Conclusion: Our results indicate that plasma oxytocin is not reduced in dementia and is unrelated to social, emotional, and behavioral features. We noted high interindividual variability in our data; hence, future investigations should consider methodological influences such as serum versus saliva and diurnal variation on oxytocin function. These results demonstrate that current measurement measures of plasma oxytocin have limited utility in determining the role of oxytocin in FTD.

Methods: Survey participants were caregivers working at 284 nursing homes in Ibaraki prefecture, Japan. The survey period was from September 2020 to March 2021.

The Hospital Anxiety and Depression Scale (HADS) was used to evaluate participants’ depression and anxiety. Results: In total, 676 participants completed the survey; 350 (52.5%) were with anxiety symptoms and 378 (56.7%) were with depressive symptoms (scores exceeding the HADS cut-off points). The risk for anxiety was associated with being care worker or social worker. The risk of anxiety or depression was high when family caregivers’ mental state changed.

The advantage of mobile interventions has been recognized due to its freedom from time and space restrictions. Objectives: A systematic review and meta-analysis was conducted to evaluate effectiveness of app-based mobile interventions for dementia caregivers. Method: We searched nine different databases including CINAHL, the Cochrane Library, Embase, MEDLINE, PsycINFO, the ACM digital library, IEEE Xplore, KoreaMed, and RISS for publications on app-based mobile interventions targeting dementia caregivers published in English or Korean. Meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) version 3.0. Standard mean difference (SMD) was used to estimate the effectiveness of the intervention on caregiver-related outcomes of caregiver burden, depression, stress, caregiving competency, and quality of life (QoL). Results: Five studies (three randomized controlled trials and two quasi-experimental studies) with a total of 230 participants were included. Using a mobile device, interventions were used to provide information and feedback, perform monitoring, and conduct skill training. Pooled analysis showed favorable effects of app-based mobile interventions for caregivers on caregiver burden (SMD = −0.315, 95% CI: −0.681 to 0.052), depression (SMD = −0.236, 95% CI: −0.517 to 0.046), stress (SMD = −0.295, 95% CI: −0.708 to 0.118), competency (SMD = 0.434, 95% CI: 0.093–0.775), and QoL (SMD = 0.794, 95% CI: 0.310–1.278). Conclusion: Types of mobile devices, lengths, and contents of interventions varied between included studies. Given that only five studies were included, the current meta-analysis could not confirm the effectiveness of app-based mobile interventions.

Higher cognitive function is reported in many studies to be associated with better functional outcomes; however, evidence from longitudinal study is lacking. Therefore, in the present study, the association between cognitive function and longitudinal changes of functional outcome was investigated based on stroke severity. Furthermore, whether the effect of cognitive function remained consistent after controlling for depression was investigated. Methods: The data of 423 stroke patients (292 minor strokes, 93 moderate strokes, and 38 severe strokes) were collected. Baseline Mini-Mental State Examination (MMSE) score was considered a predictor, and change of modified Rankin Scale (mRS) score during 12 months of follow-up was the outcome. First, the association between the baseline MMSE score and longitudinal change in the mRS score was analyzed using linear mixed-effects models. Fixed effects were MMSE score group, time, and MMSE score group × time interaction. Additional adjustment was made for the Geriatric Depression Scale (GDS) score. Results: Among the 423 subjects, the mean age was 73.5 years, and 43.4% were female. In the minor stroke group, the high MMSE score group had a decreased mRS score, and the low MMSE score group had an increased mRS score (p < 0.001). This association remained after additional adjustment of the GDS score. Association was not observed between cognitive function and functional recovery in the moderate or severe stroke group. Conclusion: After ischemic stroke, higher baseline global cognitive function was a predictive factor for better functional recovery regardless of depression symptoms in the minor stroke group.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":"51 1","pages":"168 - 174"},"PeriodicalIF":2.4,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45265388","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}
