Following this puts new work involving it at the top of your briefing, with a note saying why it is there. Links are taken from the source record, never inferred.
Expert consensus framework proposing epidemiological methods and a structured data-to-action approach for brain health measurement, policy and equity—not a primary empirical study.
Cross-sectional observational study with modest effect sizes (partial η² = 0.035–0.058) and surrogate neuroimaging endpoints; findings are exploratory and require confirmation in prospective designs.
Systematic review of 96 observational and interventional studies showing consistent association between abdominal obesity and cognitive decline in middle-aged adults, with identified biological mechanisms, though causality is not established and intervention evidence remains limited.
A narrative systematic review synthesizing fragmented evidence across heterogeneous studies with inconsistent methodologies, diagnostic criteria, and sampling approaches; identifies research trends and gaps rather than establishing definitive epidemiological or causal estimates.
A comprehensive narrative review synthesizing evidence on geriatric mental disorder pathophysiology, management, and emerging approaches; provides clinical roadmap rather than new primary evidence.
Population-based cohort with 23-year follow-up and competing risk methodology identifies depressive symptoms as associated with dementia mortality, but uses death-certificate-coded outcomes rather than clinically confirmed dementia diagnoses, limiting causal inference.
Large, well-designed longitudinal cohort study with up to 18 years of follow-up, prespecified statistical correction, and consistent associations across cognitive and neuroimaging endpoints, though observational design and potential confounding limit practice-changing claims.
This is a consensus statement from multidisciplinary expert work groups convened by the American Heart Association to address clinical management gaps; it provides recommendations for practice but does not present original trial data or evidence synthesis.
