Half of children in foster care experience clinically significant mental health disturbances, compared with 22% in the general population. Even with modern policy and screening, major depressive disorder affects 20% of foster youth ages 12 to 18 and up to 25% experience PTSD. These gaps between need and care help explain why outcomes like homelessness and incarceration can surface years later.
