Unlabelled: Nighttime agitation is a prevalent symptom in persons with Alzheimer's disease (AD). Effective treatments are absent due to our limited knowledge of its etiology. We hypothesized that restless legs syndrome (RLS), a common neurological sensorimotor disorder of uncomfortable leg sensations that appear at night and interfere with sleep, might be a cause for nighttime agitation in persons with AD. RLS is infrequently identified in persons with AD because traditional diagnosis is dependent on patients answering complex questions about their symptoms. With a validated observational tool for RLS diagnosis, the Behavioral Indicators Test-Restless Legs, we aim to diagnose RLS and determine the effect of gabapentin enacarbil (GEn) compared to placebo on nighttime agitation, sleep, antipsychotic medications, and the mechanism for these effects. We hypothesize that frequency of RLS behaviors will mediate the relationship between GEn and nighttime agitation. This study is an 8-week, double-blind, placebo-controlled, randomized pilot clinical trial, followed by an 8-week open-label trial, that is being conducted in long-term care settings and private homes. The results of this study may shift, personalize, and improve standards of care for treatment of nighttime agitation; reduce aggression and other nighttime agitation behaviors; and improve sleep.
Targets: Persons with AD with nighttime agitation potentially caused by RLS.
Intervention Description: Diagnose RLS and determine the effect of GEn.
Mechanisms Of Action: The frequency of RLS behaviors will mediate the relationship between GEn and nighttime agitation.
Outcomes: Determine the effect of GEn on nighttime agitation, sleep, and antipsychotic medications.
Trial Registration: ClinicalTrials.gov Identifier: NCT03082755 (Date of registration March 6, 2017). [Research in Gerontological Nursing, 13(6), 280-288.].

Unobtrusive Nighttime Movement Monitoring to Support Nursing Home Continence Care: Algorithm Development and Validation Study.

Background: The rising prevalence of urinary incontinence (UI) among older adults, particularly those living in nursing homes (NHs), underscores the need for innovative continence care solutions. The implementation of an unobtrusive sensor system may support nighttime monitoring of NH residents' movements and, more specifically, the agitation possibly associated with voiding events.
Objective: This study aims to explore the application of an unobtrusive sensor system to monitor nighttime movement, integrated into a care bed with accelerometer sensors connected to a pressure-redistributing care mattress.
Dementia Subtypes Defined Through Neuropsychiatric Symptom-Associated Brain Connectivity Patterns.
JAMA Netw Open
July 2024
Department of Bioengineering, Lehigh University, Bethlehem, Pennsylvania.
Importance: Understanding the heterogeneity of neuropsychiatric symptoms (NPSs) and associated brain abnormalities is essential for effective management and treatment of dementia.
Objective: To identify dementia subtypes with distinct functional connectivity associated with neuropsychiatric subsyndromes.
Design, Setting, And Participants: Using data from the Open Access Series of Imaging Studies-3 (OASIS-3; recruitment began in 2005) and Alzheimer Disease Neuroimaging Initiative (ADNI; recruitment began in 2004) databases, this cross-sectional study analyzed resting-state functional magnetic resonance imaging (fMRI) scans, clinical assessments, and neuropsychological measures of participants aged 42 to 95 years.
Comparative efficacy and safety of olanzapine and risperidone in the treatment of psychiatric and behavioral symptoms of Alzheimer's disease: Systematic review and meta-analysis.
Medicine (Baltimore)
July 2024
Department of Geriatric Psychiatry, Quzhou Third Hospital, Quzhou, China.
Objectives: Olanzapine and risperidone have emerged as the most widely used drugs as short-term prescription in the treatment of behavioral disturbances in dementia. The present systematic review and meta-analysis was hence performed to investigate the effectiveness and safety profile of olanzapine and risperidone in the treatment of behavioral and psychological symptoms of dementia (BPSD), aiming to provide updated suggestion for clinical physicians and caregivers.
Design: Prospective controlled clinical studies were included, of which available data was extracted.

Background And Objectives: Dementia presents not only differing neuropsychiatric symptoms (NPS) across Alzheimer disease (AD), frontotemporal dementia (FTD), dementia with Lewy bodies (DLB) but also subjective cognitive decline (SCD). This study examined sex-based variations in NPS severity and progression across these conditions.
Methods: We performed a longitudinal cohort study including 1,068 participants.
