Hyperactivity is a condition when a person seems to move about constantly, including in situations in which it is not appropriate; or excessively fidgets, taps, or talks. In adults, it may be extreme restlessness or wearing others out with constant activity.

On the other hand, Impulsivity is when a person makes hasty actions that occur in the heat of the moment and that may have high potential for harm; or a desire for immediate rewards or inability to delay gratification. An impulsive person may be socially intrusive and may excessively interrupt others or make important decisions without considering the long-term consequences.

People with symptoms of hyperactivity-impulsivity may often:

• Fidget and squirm in their seats
• Leave their seats in situations when staying seated is expected, such as in the classroom or in the office
• Run or dash around or climb in situations where it is inappropriate. Teens and adults with hyperactivity-impulsivity may often feel restless
• Be unable to play or engage in hobbies quietly.
• Be constantly in motion or “on the go,” or act as if “driven by a motor”
• Talk nonstop
• Blurt out an answer before a question has been completed, finish other people’s sentences, or speak without waiting for a turn in conversation
• Have trouble waiting his or her turn
• Interrupt or intrude on others, for example in conversations, games, or activities.
