Motivation: Physical activity may alleviate depression by improving brain health and potentially reversing brain volume deficits.
Goal(s): To explore the relationship between exercise intensity and brain volumes in individuals with and without depression, focusing on different brain regions.
Approach: Analyzed 6,458 participants to assess brain volumes based on physical activity levels. Linear regression and one-way ANOVA examined exercise intensity’s effect on brain volume, controlling for age and sex.
Results: Depressed individuals had smaller brain volumes, while those engaging in moderate to vigorous exercise had larger volumes. Exercise intensity correlated with different regions, with the lingual cortex in depressed and the thalamus in non-depressed individuals.
Impact: This study highlights the link between physical activity and brain health in individuals with depression, demonstrating that exercise may attenuate volumetric deficits in brain regions, ultimately offering a viable therapeutic strategy to enhance mental well-being and cognitive function.
