ADHD linked to higher risk of developing mental disorders and attempted suicide, study finds

Attention deficit hyperactivity disorder is associated with a higher incidence of depression, anorexia or post-traumatic stress disorder as well as the risk of suicide attempts, a new study found. A neurodevelopmental condition, ADHD is a pattern of hyperactivity, inattention and impulsive behavior that interferes with daily functioning or development.

Once those with ADHD developed depression, they were then 42% more likely to try to take their own life.
