Objective To test the hypothesis that higher level of cognitive activity predicts older age at dementia onset in Alzheimer disease (AD) dementia.Methods As part of a longitudinal cohort study, 1,903 older persons without dementia at enrollment reported their frequency of participation in cognitively stimulating activities. They had annual clinical evaluations to diagnose dementia and AD, and the… Continue reading Cognitive Activity and Onset Age of Incident Alzheimer Disease Dementia

Impaired muscle function, including its decline, is related to greater long-term late-life dementia risk in older women
AbstractBackgroundImpaired muscle function has been identified as a risk factor for declining cognitive function and cardiovascular health, both of which are risk factors for late-life dementia (after 80 years of age). We examined whether hand grip strength and timed-up-and-go (TUG) performance, including their change over 5 years, were associated with late-life dementia events in older women and… Continue reading Impaired muscle function, including its decline, is related to greater long-term late-life dementia risk in older women
Association of Early Adulthood Hypertension and Blood Pressure Change With Late-Life Neuroimaging Biomarkers
The association between hypertension developed before midlife and late-life brain health is understudied and, because of the cardioprotective benefits of estrogen before menopause, may differ by sex. Objective To assess the association of early adulthood hypertension and blood pressure (BP) change with late-life neuroimaging biomarkers and examine potential sex differences. Design, Setting, and Participants This cohort study… Continue reading Association of Early Adulthood Hypertension and Blood Pressure Change With Late-Life Neuroimaging Biomarkers
Dietary magnesium intake is related to larger brain volumes and lower white matter lesions with notable sex differences
PurposeTo examine the association between dietary magnesium (Mg) intake and brain volumes and white matter lesions (WMLs) in middle to early old age.MethodsParticipants (aged 40–73 years) from UK Biobank (n = 6001) were included and stratified by sex. Dietary Mg was measured using an online computerised 24 h recall questionnaire to estimate daily Mg intake. Latent class… Continue reading Dietary magnesium intake is related to larger brain volumes and lower white matter lesions with notable sex differences
Association of Bone Mineral Density and Dementia: The Rotterdam Study
Background & Objective: Low bone mineral density and dementia commonly co-occur in the elderly, with bone loss accelerating in dementia patients due to physical inactivity and poor nutrition. However, uncertainty persists over the extent to which bone loss already exists prior to the onset of dementia. Therefore, we investigated how dementia risk was affected by… Continue reading Association of Bone Mineral Density and Dementia: The Rotterdam Study

Pioglitazone Use and Reduced Risk of Dementia in Patients With Diabetes Mellitus With a History of Ischemic Stroke
Background and objectives: Previous studies have reported the protective effect of pioglitazone on dementia in type 2 diabetic mellitus (DM) patients. Recent studies have shown that pioglitazone also lowers the risk of primary and recurrent stroke. Understanding the characteristics of patients particularly associated with the benefits of pioglitazone would facilitate its personalized use by specifying… Continue reading Pioglitazone Use and Reduced Risk of Dementia in Patients With Diabetes Mellitus With a History of Ischemic Stroke
Race Differences in the Association Between Sleep Medication Use and Risk of Dementia
Abstract: Background:The effect of sleep medications on cognition in older adults is controversial, possibly dependent upon sleep quality, and may differ by race. Objective:To determine the longitudinal association between sleep medication use and incident dementia over 15 years, and to explore whether the association is independent of nighttime sleep disturbances and if it differs by race.… Continue reading Race Differences in the Association Between Sleep Medication Use and Risk of Dementia
The reversible impairment of behavioral variant frontotemporal brain sagging syndrome: Challenges and opportunities
Due to loss of brain buoyancy, spontaneous spinal cerebrospinal fluid (CSF) leaks cause orthostatic headaches but also can cause symptoms indistinguishable from behavioral variant frontotemporal dementia (bvFTD) due to severe brain sagging (including the frontal and temporal lobes), as visualized on brain magnetic resonance imaging. However, the detection of these CSF leaks may require specialized… Continue reading The reversible impairment of behavioral variant frontotemporal brain sagging syndrome: Challenges and opportunities
