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. Alternative oxytocin measures may prove more sensitive and should be considered when conducting clinical trials.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45783303","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}

Healthcare workers fighting COVID-19 experience mental health issues. Caregivers in nursing homes experienced increased psychological distress and concern about deterioration of their mental health. We conducted a large-scale web-based survey exploring mental health among caregivers working in nursing homes during the COVID-19 pandemic with the aim of identifying their support needs. Methods: Survey participants were caregivers working at 284 nursing homes in Ibaraki prefecture, Japan. The survey period was from September 2020 to March 2021. Participants responded to a questionnaire covering gender, age, occupation, infections at facilities, infection protection, changes in nursing home users, cooperation with other medical institutions, and prejudice/discrimination. 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. Discussion/Conclusion: This study found that caregivers working in nursing homes were exposed to high levels of stress during the COVID-19 pandemic and were at high risk for developing depression and anxiety.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42488754","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}

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. However, this study suggests that app-based mobile interventions for dementia caregivers might have positive effects on diverse caregiving-related issues such as caregiver burden, depression, stress, competency, and QoL.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45318465","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}

The “Emergency Room Evaluation and Recommendations” (ER2) tool decreases the length of stay (LOS) in the hospital when older people visiting ED are hospitalized after an index ED visit, regardless of their cognitive status. Its effect on hospital admissions has not yet been examined in older people with MNCD visiting ED. This study aimed to examine whether ER2 recommendations were associated with incident hospital admissions and LOS in ED in older people with MNCD visiting ED. Methods: A total of 356 older people with MNCD visiting ED of the Jewish General Hospital (Montreal, Quebec, Canada) were recruited in this non-randomized, pre-post-intervention, single arm, prospective and longitudinal open label trial. ED staff and patients were blinded of the ER2 score, and patients received usual ED care during the observation period, whereas ED staff were informed about the ER2 score, and patients had ER2 tailor-made recommendations in addition to usual care during the intervention period. Hospital admissions and the LOS in ED were the outcomes. Results: There were less incident hospital admissions (odds ratio ≤ 0.61 with p ≤ 0.022) and longer LOS in ED (coefficient beta ≥4.28 with p ≤ 0.008) during the intervention period compared to the observation period.

Self-rated and informant-rated scores were used to calculate discrepancies, which were used as an indicator of awareness of functional ability. Smaller discrepancy scores were considered to reflect greater awareness on the part of PwD. PwD completed questionnaires on depression, personality, comorbidities, neuropsychiatric symptoms, and completed a measure of cognition. Informants provided ratings of stress. Univariable and multiple regressions were used to investigate factors related to ADL discrepancy. Results: A similar pattern of associations were found for both ADL discrepancy scores. Smaller discrepancy scores were associated with higher levels of depression, higher neuroticism, fewer neuropsychiatric symptoms, higher comorbidity, lower carer stress, and receipt of less than 1 hour of care per day from the informant. Discussion/Conclusion: There was a clear pattern of factors that were associated with greater awareness for both measures of functional ability. These factors associated with smaller discrepancy scores could be used to identify PwD who might benefit from targeted interventions to support their independence.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48169123","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}

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":null,"pages":null},"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}

The percentage of older adults with diabetes has also been increasing. Since diabetes mellitus is documented as a risk factor for dementia, it is important to address cognitive impairment in older adults with diabetes. Thus, this study aimed to evaluate the prevalence and associated factors of cognitive impairment among older adults with diabetes in a suburban primary health center in Thailand. Methods: A cross-sectional study in 244 diabetic patients aged 60 years or older was conducted in a primary health care unit in Pathum Thani, Thailand. Cognitive function was assessed with the validated Thai version of the Mini-Addenbrooke’s Cognitive Examination Test. Sociodemographic and health characteristic data were obtained. Results: The prevalence of cognitive impairment was 54.5% (133 out of 244). Multivariate logistic regression disclosed that factors significantly associated with cognitive impairment were ages 70–79 years compared to ages 60–69 years (odds ratio [OR] 1.90, 95% confidence interval [CI]: 1.01–3.62, p value 0.048), ages ≥80 years compared to ages 60–69 years (OR 3.65, 95% CI: 1.19–11.24, p value 0.024), education ≤ primary school (OR 7.28, 95% CI: 3.56–14.89, p value <0.001), and medication managed by caregiver compared to self-management of medication (OR 13.40, 95% CI: 1.55–116.10, p value 0.019). Conclusion: We revealed that approximately half of older adults with diabetes had cognitive impairment. This finding strongly suggests the need to include cognitive assessment in a standard clinical practice guideline for diabetic patients and to focus more on individuals who are very old, have low education, or are unable to manage their drugs by themselves.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48590115","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}

The aim was to use MRI to categorize patients according to their hippocampal atrophy status and to present prevalence of the subtypes, difference in clinical symptomatology and progression, and factors associated with hippocampal subtypes. Methods: We included 215 patients with AD who had been assessed with the clinically available MRI software NeuroQuant (NQ; CorTechs labs/University of California, San Diego, CA, USA). NQ measures the hippocampus volume and calculates a normative percentile. Atrophy was regarded to be present if the percentile was ≤5. Demographics, cognitive measurements, AD phenotypes, apolipoprotein E status, and results from cerebrospinal fluid and amyloid positron emission tomography analyses were included as explanatory variables of the hippocampal subtypes. Results: Of all, 60% had no hippocampal atrophy. These patients were younger and less cognitively impaired concerning global measures, memory function, and abstraction but impaired concerning executive, visuospatial, and semantic fluency, and more of them had nonamnestic AD, compared to those with hippocampal atrophy. No difference in progression rate was observed between the two groups. In mild cognitive impairment patients, amyloid pathology was associated with the no hippocampal atrophy group. Conclusion: The results have clinical implications. Clinicians should be aware of the large proportion of AD patients presenting without atrophy of the hippocampus as measured with this clinical MRI method in the diagnostic set up and that nonamnestic phenotypes are more common in this group as compared to those with atrophy.

However, few studies have focused on very old people (aged ≥80 years), the age group with highest prevalence of dementia. The aim was to investigate if PA associated with subsequent dementia, cognitive function, and gait speed (GS), in very old people. Methods: A population-based survey was conducted in 1999 and followed-up between 2016 and 2019 in participants ≥80 years. Altogether 541 individuals (56.2% women), 64.9 ± 4.2 years of age at baseline participated. Self-rated baseline PA was categorized into low, medium, or high. Cognitive function was assessed with the Mini-Mental State Examination (MMSE), executive function with the Frontal Assessment Battery (FAB), and GS (in meters/second) was measured over 2.4 m at follow-up. Results: During a mean of 19.0 ± 1.1 years, 175 (32.3%) developed dementia. Low or medium PA compared to high PA did not associate with subsequent dementia, and PA did not associate with future cognitive function (MMSE). PA associated with executive function (FAB) (unstandardized beta [95% confidence interval]) (0.67 [0.07–1.27]), but not after adjustments. PA associated with subsequent GS in the unadjusted model and after adjustment for age, sex, smoking, and education (0.06 [0.02–0.09], and 0.04 [0.01–0.08], respectively), but not after adding adjustment for hypertension, obesity, and glucose intolerance. Conclusion: No support was found for the hypothesis that low PA is a potential risk factor for dementia in very high age. However, PA and executive function were associated in unadjusted analyses which indicate that PA may be important for at least one aspect of cognitive function. The association between PA and GS around 2 decades later seems attenuated by cardiometabolic risk factors. Future investigations regarding PA, dementia, and cognitive decline may consider cardiometabolic risk factors such as hypertension, obesity, and glucose intolerance, and include repeated measures of PA over the life course.","PeriodicalId":11126,"journal":{"name":"Dementia and Geriatric Cognitive Disorders","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45864976","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}
