Because ADHD develops during childhood, the information presented here focuses on children. The primary symptoms of ADHD are inattention, hyperactivity, and impulsivity. At some time in their lives, all children are inattentive, hyperactive, or impulsive. However, children with ADHD have symptoms that are noticeably more severe and consistent. They have difficulty in school and with their family and peer relationships.
There are several different types of ADHD. Some children are mainly inattentive and don't display signs of hyperactivity (classic attention deficit disorder [ADD]). However, some are hyperactive, some are impulsive, and others exhibit a mixture of these symptoms.
Behaviors linked to ADHD can last into adulthood, often resulting in problems with relationships and employment. Specific symptoms include:
