A prospective population-based cohort study in the Netherlands suggests that sleep rhythm disturbances can precede amyloid-β (Aβ) deposition and may be a modifiable risk factor for Alzheimer disease (AD). From September 2018 to November 2021, 319 participants without dementia who underwent Aβ positron emission tomography (PET) were included with the […]
A UK cohort study suggested that irregular sleep may represent a novel dementia risk factor. A random selection of 88,094 individuals (mean age 62 years, 56% women, and median sleep regularity index [SRI] 60) from a UK cohort was done between February 2013 and December 2015. The SRI was calculated […]
A US cohort study suggests that high blood pressure variability (BPV) can indicate increased incident dementia risk in older age. The study focused on 820 participants (mean age, 77.0 years; 58.0% females) with data of brain autopsy and midlife to late-life BP. A mean of 28.4 yearly SBP measurements were […]
A US cohort study suggested that metformin cessation was associated with increased dementia incidence. The cohort consisted of 12 220 early terminators and 29 126 routine users, respectively (women 46.2% and 46.6%, respectively; mean age at start of first metformin prescription 59.4 and 61.1 years, respectively). Early terminators had 1.21 times the […]
