Attention-deficit/hyperactivity disorder is a neurobehavioral disorder characterized by a combination of inattentiveness, distractibility, hyperactivity, and impulsivity.
Five to seven percent of children are diagnosed with this developmental disorder.
Maintaining fulfilling relationships can be a challenge for people with attentional problems. Because they are easily distracted, they may not appear to be listening to loved ones, or they may forget social plans or important errands.
Addiction is a condition that results when a person ingests a substance (e.g., alcohol, cocaine, nicotine) or engages in an activity (e.g., gambling, sex, shopping) that can be pleasurable but the continued use/act of which becomes compulsive and interferes with ordinary life responsibilities, such as work, relationships, or health.
