#Handedness

A sweeping new meta-analysis has revealed that individuals with mental or neurodevelopmental disorders are about 1.5 times more likely to exhibit non-right-handedness — meaning left-handedness or mixed-handedness — than the general population, sharpening the focus on how biological factors may intersect with mental health. Published in the prestigious journal Psychological Bulletin, the study synthesizes an unprecedented dataset drawn from over 202,000 people and provides fresh insights into the subtle ways brain development may be linked to mental health risk (psypost.org).
