Purpose: Antipsychotic use in Alzheimer disease (AD) is associated with adverse events and mortality. Whilst postulated to cause/exacerbate orthostatic hypotension (OH), the exact relationship between antipsychotic use and OH has never been explored in AD-a group who are particularly vulnerable to neuro-cardiovascular instability and adverse effects of medication on orthostatic blood pressure (BP) behaviour., Methods: We analysed longitudinal data from an 18-month trial of Nilvadipine in mild-moderate AD. We assessed the effect of long-term antipsychotic use (for the entire 18-month study duration) on orthostatic BP phenotypes measured on eight occasions, in addition to the relationship between antipsychotic use, BP phenotypes and incident falls., Results: Of 509 older adults with AD (aged 72.9 ± 8.3 years, 61.9% female), 10.6% (n = 54) were prescribed a long-term antipsychotic. Over 18 months, long-term antipsychotic use was associated with a greater likelihood of experiencing sit-to-stand OH (ssOH) (OR: 1.21; 1.05-1.38, p = 0.009) which persisted on covariate adjustment. Following adjustment for important clinical confounders, both antipsychotic use (IRR: 1.80, 1.11-2.92, p = 0.018) and ssOH (IRR: 1.44, 1.00-2.06, p = 0.048) were associated with a greater risk of falls/syncope over 18 months in older adults with mild-moderate AD., Conclusion: Even in mild-to-moderate AD, long-term antipsychotic use was associated with ssOH. Both antipsychotic use and ssOH were associated with a greater risk of incident falls/syncope over 18 months. Further attention to optimal prescribing interventions in this cohort is warranted and may involve screening older adults with AD prescribed antipsychotics for both orthostatic symptoms and falls., (© 2024.

Context: The assessment of decision-making ability of older adults with cognitive impairment is a complex challenge that geriatricians often face in relation to risk-taking situations (driving, aging in place, financial decisions, etc.). However, there are no clear and consensual practice guidelines. An overview of current practices and needs seemed necessary., Methods: We co-created and conducted an online survey to describe practice and knowledge, among European geriatricians. The survey was structured in 3 parts: a description of the professional's practice regarding cognitive impairment, a specific questionnaire about everyday risky decision-making evaluation and an investigation of the clinician's knowledge about relevant ethical and legal recommendations. Each part consisted of both multiple choice and open questions, analyzed through descriptive statistics and qualitative analysis methods., Results: Based on the responses of 123 geriatricians across Europe, our survey showed that clinical interview is the cornerstone of geriatric assessment of decision-making ability of patients with mild to moderate dementia. When faced with risk-taking dilemma situations, geriatricians tend to favor a context of safety above autonomy, but they can support risky decision-making if it is consistent with the patient's previous lifestyle, depending on the degree of risk to self and others, on the decision-making ability assessed, and if there is some form of shared decision-making., Conclusion: Assessing decision-making ability is challenging for geriatricians, who in our study relied more on their clinical interview and global cognitive tests than more in-depth evaluations. Supporting independent decision-making, when associated with risk-taking, requires better detection and anticipation shared with the patient environment., (© 2023.

Background: The aim of this study was to validate the 8-item Centre for Epidemiological Studies Depression Scale (CES-D-8) against the 20-item version (CES-D-20) in a large sample of community-dwelling older people., Methods: Scales were compared for correlation and internal consistency. The ideal cut-off score for the CES-D-8 was determined by comparing scores ranging from 7 to 12 on the CES-D-8 to CES-D-20., Results: 8033 participants were included. The Spearman co-efficient between the scales was 0.8980 indicating high degree of correlation. At a score of 9/24, the sensitivity and specificity of the CES-D-8 were 98 and 83%, respectively. The Cohen's κ for a score of 9 was 0.7855, indicating strong agreement and the ROC area was 0.88., Conclusion: When compared to the CES-D-20, the CES-D-8 is a valid and reliable measure of depressive symptoms in community-dwelling older people, and a score of 9 can be used to identify those with clinically significant symptoms., (© 2017.
