Attention-deficit/hyperactivity disorder begins in childhood, with key symptoms including inattention, hyperactivity, and impulsivity.
Attention-deficit/hyperactivity disorder (ADHD) is characterized by inattentive, hyperactive, or impulsive behavior that goes beyond an age-appropriate level. Symptoms must appear before the age of 12 years and last for more than six months. Major symptoms include difficulty sustaining focus, disorganization, forgetfulness, fidgeting, interrupting, and impulsive behavior. In the DSM-5, this disorder has three subtypes: predominantly inattentive presentation, predominantly hyperactive/impulsive presentation, and combined presentation. The most common subtype is the combined presentation, and the least common is the predominantly hyperactive/impulsive presentation.

People with ADHD often have difficulty at school, at work, and in relationships. Hyperactivity and impulsivity also increase risk for serious physical injury and substance use problems. ADHD runs in families. Up to 60 percent of adults with ADHD will pass it on to their children. Medication, academic support, and talk therapy are used to manage ADHD. ADHD persists throughout the lifespan, although symptoms may become less severe with age.
