One in five young adults has personality disorder
Almost one in five young American adults has a personality disorder that interferes with everyday life, and even more abuse alcohol or drugs, researchers reported in the most extensive study of its kind.
The first large, population-based study to follow children with attention-deficit hyperactivity disorder into adulthood shows that ADHD often doesn't ``go away,'' and that children with ADHD are more likely to have other psychiatric disorders as adults.
