ADHD can make life difficult for family and neighbors. Children with ADHD tend to have poor self-esteem and so have trouble interacting with and being accepted by peers and adults. In later years, they are at increased risk of alcohol and drug abuse and other delinquent behavior. The sort of behavior that identifies the disorder is that the child is often easily distracted and is constantly on the move. He or she may fail to think before acting, to the point that it raises safety concerns.
