Office-based Framingham Heart study–cardiovascular risk scores (FHS-CVS) were derived at ages 36, 53, and 69 years using systolic blood pressure, antihypertensive medication usage, smoking, diabetic status, and body mass index. Analysis models adjusted for age at imaging, sex, APOE genotype, socioeconomic position, and, where appropriate, total intracranial volume. ..At all points, these scores were associated… Continue reading Associations Between #vascular Risk Across Adulthood and #Brain Pathology in Late Life Evidence From a British Birth Cohort

#Antihypertensive medications and risk for incident #dementia and #Alzheimer’s disease: a meta-analysis of individual participant data from prospective cohort studies
..We assessed the association of incident dementia and clinical Alzheimer's disease with use of five AHM classes, within strata of baseline high (systolic blood pressure [SBP] ≥140 mm Hg or diastolic blood pressure [DBP] ≥90 mm Hg) and normal (SBP <140 mm Hg and DBP <90 mm Hg) blood pressure. ..There were 3728 incident cases… Continue reading #Antihypertensive medications and risk for incident #dementia and #Alzheimer’s disease: a meta-analysis of individual participant data from prospective cohort studies
#Insomnia symptoms and risk of cardiovascular diseases among 0.5 million adults. A 10-year cohort
..Three insomnia symptoms were assessed with self-reported difficulties in initiating or maintaining sleep, early morning awakening, and daytime dysfunction for at least 3 d/wk at baseline ..Cox regressions showed that 3 insomnia symptoms were associated with increased risk of total #CVD, with respective adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of 1.09 (95%… Continue reading #Insomnia symptoms and risk of cardiovascular diseases among 0.5 million adults.

Intact global #cognitive and #olfactory ability predicts lack of transition to #dementia
Odor identification deficits characterize Alzheimer's disease and other dementias ..Smell Identification Test, which includes the 12-item Brief Smell Identification Test (B-SIT) ..In covariate-adjusted survival analyses, impairment on the Blessed Orientation Memory Concentration Test and B-SIT each predicted dementia (n = 109), primarily Alzheimer's disease (n = 101). Among participants with intact olfactory (B-SIT ≥ 11/12… Continue reading Intact global #cognitive and #olfactory ability predicts lack of transition to #dementia
Convergent evidence for predispositional effects of #brain gray matter volume on #alcohol consumption
Smaller right dorsolateral prefrontal cortex (DLPFC; i.e., middle and superior frontal gyri) and insula GMVs were associated with increased alcohol use across samples. Family-based and prospective longitudinal data suggest these associations are genetically-conferred and that DLPFC GMV prospectively predicts future use and initiation. Genomic risk for alcohol use was enriched in gene-sets preferentially expressed in… Continue reading Convergent evidence for predispositional effects of #brain gray matter volume on #alcohol consumption
Serum elaidic acid concentration and risk of #dementia. The Hisayama study
The associations between #trans fatty acids and dementia have been unclear. We investigated the prospective association between serum elaidic acid (trans 18:1 n-9) levels, as an objective biomarker for industrial trans fat, and incident dementia and its subtypes. Higher serum elaidic acid levels were significantly associated with greater risk of developing all-cause dementia (p for… Continue reading Serum elaidic acid concentration and risk of #dementia. The Hisayama study
Dietary #salt promotes cognitive impairment through tau phosphorylation
Dietary habits and vascular risk factors promote both #Alzheimer’s disease and cognitive impairment caused by vascular factors. Furthermore, accumulation of hyperphosphorylated tau, a microtubule-associated protein and a hallmark of Alzheimer’s pathology, is also linked to vascular cognitive impairment. In mice, a salt-rich diet leads to cognitive dysfunction associated with a nitric oxide deficit in cerebral… Continue reading Dietary #salt promotes cognitive impairment through tau phosphorylation
Regulation of #lifespan by #neural excitation and REST
..Here we show that extended longevity in humans is associated with a distinct transcriptome signature in the cerebral cortex that is characterized by downregulation of genes related to neural excitation and synaptic function. In Caenorhabditis elegans, neural excitation increases with age and inhibition of excitation globally, or in glutamatergic or cholinergic neurons, increases longevity. Furthermore,… Continue reading Regulation of #lifespan by #neural excitation and REST
Effects of #tranexamic acid on death, disability, vascular occlusive events and other morbidities in patients with acute traumatic #brain injury (CRASH-3): a randomised, placebo-controlled trial
Tranexamic acid reduces surgical bleeding and decreases mortality in patients with traumatic extracranial bleeding. Intracranial bleeding is common after traumatic brain injury (TBI) and can cause brain herniation and death. We aimed to assess the effects of tranexamic acid in patients with TBI. The risk of head injury-related death reduced with tranexamic acid in patients… Continue reading Effects of #tranexamic acid on death, disability, vascular occlusive events and other morbidities in patients with acute traumatic #brain injury (CRASH-3): a randomised, placebo-controlled trial
