Introduction: More women than men develop Alzheimer's disease, yet women perform better and show less decline on episodic memory measures, a contradiction that may be accounted for by modifiable risk factors for dementia.

Methods: Associations among age, sex, modifiable dementia risk factors, and cognition were measured in a cross-sectional online sample (= 21,840, ages 18 to 89).

Results: Across four tests of associative memory and executive functions, only a Face-Name Association task revealed sex differences in associative memory that varied by age. Men had worse memory than women (the equivalent of performing similar to someone 4 years older) across ages. Men had larger age differences than women (ie, worse memory in older ages) among people with no to one risk factor, but not those with multiple risk factors.

Discussion: Because the relationship between dementia risk factors and age-related memory differences varies between men and women, sex-specific dementia prevention approaches are warranted.

Study Objectives: Insomnia with objective short sleep duration is associated with increased hypertension risk. We aimed to explore the mechanism underlying the association between objective short sleep duration and hypertension in patients with chronic insomnia disorder (CID) by multi-omics.

Methods: CID was defined according to International Classification of Sleep Disorders-3, and objective short sleep was based on the median value of total sleep time of the overall subjects during an overnight polysomnography.

Importance: Ultraprocessed foods (UPF), characterized as shelf-stable but nutritionally imbalanced foods, pose a public health crisis worldwide. In adults, UPF consumption is associated with increased obesity risk, but findings among children are inconsistent.

Objectives: To examine the associations among UPF intake, anthropometric adiposity indicators, and obesity status in Canadian children.

Behavioural and psychological symptoms of people with dementia in acute hospital settings: a systematic review and meta-analysis.

Age Ageing

January 2025

Centre for Psychiatry and Mental Health, Wolfson Institute of Population Health, Queen Mary University of London, London, E13 8SP, United Kingdom of Great Britain and Northern Ireland.

Background: Behavioural and psychological symptoms of dementia (BPSD) can complicate acute hospital care, but evidence on BPSD in this setting is heterogeneous.

Objective: To determine the prevalence of BPSD in acute hospitals and explore related risk factors, treatments, and outcomes (PROSPERO: CRD42023406294).

Methods: We conducted a systematic review and meta-analysis by searching Cochrane Library, MEDLINE, and PsycINFO for studies on BPSD prevalence among older people with dementia during their acute hospital admissions (up to 5 March 2024).

Brain network dynamics have been extensively explored in patients with subjective cognitive decline (SCD). However, these studies are susceptible to individual differences, scanning parameters, and other confounding factors. Therefore, how to reveal subtle SCD-related subtle changes remains unclear.

The current study examined cross-sectional and longitudinal associations between nocturia and frailty in a cohort of men and women aged 60 years and older, as evidence on this topic was lacking. We analyzed baseline and follow-up data (n = 1671) from the Berlin Aging Study II (BASE-II), a prospective longitudinal cohort study focusing on the factors associated with "healthy" vs. "unhealthy" aging.
