Attention-deficit/hyperactivity disorder (previously known as attention deficit disorder, or ADD) is a neurobehavioral disorder characterized by core symptoms of inattentiveness, distractibility, hyperactivity, and impulsivity.
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 in which a person engages in the use of a substance or in a behavior for which the rewarding effects provide a compelling incentive to repeatedly pursue the behavior despite detrimental consequences.
