Symptoms are often misinterpreted or neglected, which could lead to late diagnosis, reducing the choices available regarding future care. Considering that most nurses caring for the elderly will work with people with dementia in the future, there is concern surrounding their ability to meet the needs of these patients, requiring them to obtain the necessary knowledge and positive attitudes for treatment. Aims: To describe the knowledge of and attitudes toward dementia among nursing staff working in residential care facilities for elderly populations in India. Methods: A cross-sectional survey was conducted in 3 nursing homes in India in which 15 nursing staff conducted self-assessments of their knowledge and attitudes toward dementia using the Alzheimer’s Disease Knowledge Scale (ADKS) and the Attitude toward Alzheimer’s Disease and Related Dementias Scale (DAS) for each respective assessment. Descriptive statistics were used to describe staffs’ attitudes and knowledge concerning dementia. Continuous variables were presented as means ± SD, while the categorical variables were presented as percentages. Results: Although the majority of the participants answered that Alzheimer’s disease cannot be cured, about half reported that people with dementia, in rare cases, can recover from the disease. While all participants agreed that people with dementia can feel when others are kind to them, almost half disagreed that people living with dementia can enjoy life.

The PFS captures the presence of subjective experience of physical fatigue as well as its impact on daily functioning. Objectives: We aimed to investigate whether different variables (cognition, neuropsychiatric symptoms, disease-related measures) are associated with the experience of physical fatigue in comparison to fatigue affecting daily functioning. Method: Sixty-two non-demented PD patients were evaluated through questionnaires assessing fatigue, daytime sleepiness, apathy, depression, anxiety, and cognition. Items of fatigue were classified and summarized into two index variables measuring either the subjective experience of physical fatigue or the impact of fatigue on daily functioning. Linear regression with a stepwise elimination procedure was conducted to select the significant predictors for each index variable separately. Results: Subjective experience of physical fatigue (Model 1; r2 = 0.46; p <0.01) was significantly associated with higher levels of depression (b =0.07; p <0.01), anxiety (b =0.03; p <0.05), and lower performances in verbal episodic memory (b =–0.16; p <0.05). Fatigue affecting daily functioning (Model 2; r2 = 0.44; p <0.05) was significantly related to higher levels of depression (b = 0.07; p < 0.01), anxiety (b = 0.03; p > 0.05), and lower motor functioning (b = 0.01; p = 0.05). Conclusions: In conclusion, our work supports associations between fatigue and other neuropsychiatric symptoms in PD and extends prior work suggesting that motor disturbances are specifically linked to fatigue-related impairment of daily functioning, but not to the subjective experience of physical fatigue.","PeriodicalId":38017,"journal":{"name":"Dementia and Geriatric Cognitive Disorders Extra","volume":"9 1","pages":"344 - 351"},"PeriodicalIF":2.3,"publicationDate":"2019-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000498883","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42365930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test battery included the following: the FES-I, the Short Physical Performance Battery, the Geriatric Depression Scale, the Bristol Activity Daily Living Scale, and the Quality of Life-Alzheimer’s Disease Scale.

Objective: To investigate the efficacy and safety of switching from oral ChEIs to rivastigmine transdermal patch in patients with AD. Methods: In this multicenter, open-label, phase IV study in outpatient clinics in Japan, patients with mild-moderate AD who had a poor response to or experienced difficulty in continuing donepezil or galantamine were switched to rivastigmine transdermal patch (5 cm2; loaded dose 9 mg, delivery rate 4.6 mg/24 h) with a 1-step titration in week 4 (10 cm2; loaded dose 18 mg, delivery rate 9.5 mg/24 h), which was continued for 4 weeks in the titration period and 16 weeks in a maintenance period. The primary endpoint was the change in Mini-Mental State Examination (MMSE) total score from baseline to week 24. Results: A total of 118 patients were enrolled and switched to rivastigmine, of which 102 completed the 24-week study. The MMSE total score was essentially unchanged during the study, with a least-square mean change (SD) of −0.35 (2.64) at week 24 (p = 0.1750).

The Cognitive Assessment Battery (CAB) was introduced as a sensitive tool to detect cognitive decline in primary care. However, primary care validation is lacking. Therefore, we investigated the accuracy of the CAB in a primary care population. Objective: To investigate the accuracy of the CAB in a primary care population. Methods: Data from 46 individuals with cognitive impairment and 33 individuals who visited the primary care with somatic noncognitive symptoms were analyzed. They were investigated with the MMSE, the CAB, and a battery of neuropsychological tests; they also underwent consultation with a geriatric specialist. The accuracy of the CAB was assessed using c-statistics and the area under the receiver operating characteristic curve (AUC) was used to quantify the binary outcomes (“no cognitive impairment” or “cognitive impairment”). Results: The “cognitive impairment” group was significantly different from the unimpaired group for all the subtests of the CAB. When accuracy was based on binary significant reduction or not in one or several domains of the CAB, the AUC varied between 0.685 and 0.772. However, when a summation or logistic regression of several subcategories was performed, using the numerical values for each subcategory, the AUC was >0.9. For comparison, the AUC for the MMSE was 0.849. Conclusions: The accuracy of the CAB in a primary care population is poor to good when using binary cutoffs. Accuracy can be improved to high when using a summation or logistic regression of the numerical data of the subcategories. Considering CAB time, lack of adequate age norms, and a good accuracy for the MMSE, implementation of the CAB in primary care is not recommended at present based on the results of this study.","PeriodicalId":38017,"journal":{"name":"Dementia and Geriatric Cognitive Disorders Extra","volume":"9 1","pages":"294 - 301"},"PeriodicalIF":2.3,"publicationDate":"2019-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000501365","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43248331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
