Bidirectional Association Between Cognitive Function and Depressive Symptoms Mediated by Physical Activity in UK Community-Dwelling Adults
Exercise buffers against worsening depression and cognitive decline together, supporting dual-benefit fitness interventions.
This longitudinal cohort study demonstrates a bidirectional relationship between cognitive function and depression in UK community-dwelling older adults, with physical activity mediating this association and buffering against mutual worsening. Findings support exercise interventions as dual-purpose strategies for preventing both cognitive decline and late-life depression.
