A prospective population-based cohort study in the Netherlands suggests that in individuals at low and intermediate genetic risk, favorable modifiable-risk profiles are associated with a lower risk of dementia compared to unfavorable profiles. However, these protective associations were not found in those at high genetic risk. The study included 6,352 […]
A UK epidemiological study revealed that high and increasing blood pressure (BP) from early adulthood into midlife seems to be associated with increased white matter hyperintensity volume (WMHV) and smaller brain volumes at 69–71 years of age. The study included 502 individuals from a cohort born throughout mainland Britain in […]
Two US studies showed that more intensive blood pressure (BP) management was associated with less progression of cerebral small vessel ischemic diseaseand a greater decrease in total brain volume; BP patterns in midlife and late life may be associated with differing risks for incident dementia. The substudy of a randomized […]
Two observational cohort studies revealed that altered levels of hemoglobin and liver function markers were associated with Alzheimer disease (AD). The first study included 12,305 participants without dementia of the population-based Dutch cohort (mean age 64.6 years, 57.7% women). During a mean follow-up of 12.1 years, 1,520 individuals developed dementia, […]
A UK retrospective cohort study suggested that a favorable lifestyle was associated with a lower dementia risk among participants with high genetic risk. The study included a total of 196 383 individuals (mean 64.1 years; 52.7% women) from 2006 to 2010, and followed up for 1 545 433 person-years (median follow-up, 8.0 years). […]
The Global Council on Brain Health (GCBH), an independent collaborative of scientists, health professionals, scholars and policy experts from around the world who are working in areas of brain health related to human cognition concluded that there is no convincing evidence to recommend dietary supplements for brain health in healthy […]
A genome-wide study of bipolar disorder (BD) revealed an extensive polygenic genetic architecture of the disease, implicate brain calcium channels and neurotransmitter function in BD etiology, and confirmed that BD is part of a spectrum of highly correlated psychiatric and mood disorders. The study included 20,352 cases and 31,358 controls […]
The Food and Drug Administration (FDA) is requiring a Boxed Warning, the most prominent warning, to be added to certain common prescription insomnia medicines because of sleep behaviors, including sleepwalking, sleep driving, and engaging in other activities while not fully awake. These complex sleep behaviors have also resulted in deaths. […]
A meta-analysis of genome-wide association studies of depression identified 102 independent variants, 269 genes, and 15 genesets associated with depression, including both genes and gene pathways associated with synaptic structure and neurotransmission. The analysis included 807,553 individuals (246,363 cases and 561,190 controls). An enrichment analysis provided further evidence of the […]
A cohort study revealed that blood neurofilament light chain (NfL) changes predict disease progression and brain neurodegeneration more than a decade before the onset of familial Alzheimer’s disease (AD). The study included 243 participants with an early-onset genetic variant known to cause dominantly inherited AD and 162 unaffected relatives as […]
