Brain-wave patterns at age 9 may predict anxiety and depression

MedicalXpress | Mai 19, 2026

A longitudinal study tracking children over a period of seven years has identified distinct brain-wave patterns emerging from age 9 that can forecast a child's vulnerability to anxiety or depression by age 13. These predictive markers reveal divergent, hemisphere-specific neurodevelopmental trajectories. Anxiety is linked to activity on the right side of the brain, while depression is tied to the left.
