Because ADHD develops during childhood, the information presented here focuses on children. The primary symptoms of ADHD are inattention, hyperactivity, and impulsivity.

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.
