Dementia Care Research and Psychosocial Factors.

Alzheimers Dement

December 2024

UK Dementia Research Institute, Care Research and Technology Centre, Imperial College London and the University of Surrey, Guildford, United Kingdom.

Background: Changes in sleep patterns are common in Alzheimer's disease and impact the quality of life of both people living with Alzheimer's (PLWA) and their caregivers. Longitudinal recordings and assessment of night-to-night variations in sleep and physiology can improve our understanding of how sleep influences clinical outcomes and caregiver wellbeing.

Method: We collected sleep diary and contactless sleep technology data (Withings sleep analyser, WSA) in community dwelling PLWA (N = 16, Age = 72.

: Hypertension is typically classified into two main groups, "dipper" and "non-dipper", based on nocturnal blood pressure decline. The coronary artery calcium score (CACS) is an essential biomarker used to assess the presence and severity of coronary artery disease (CAD). This study aims to demonstrate the relationship between CACS and hypertensive patients with moderate-to-high cardiovascular disease (CVD) risk classified as either dipper or non-dipper.

Background: Sleep deprivation can lead to increased body weight and blood pressure (BP), but the latent effects of partial sleep deprivation related to required night sentry duties within a short-term period on cardiometabolic characteristic changes in military personnel are unclear.

Aim: To investigate the association between night sentry duty frequency in the past 3 months and cardiometabolic characteristics in armed forces personnel.

Methods: A total of 867 armed forces personnel who were aged 18-39 years and did not take any antihypertensive medications in Taiwan in 2020 were included.
