Hyperactivity

Definition:

Hyperactivity is a state of excessive muscular activity. This term is also used to describe a situation when a particular portion of the body is excessively active, such as when a gland produces too much of its particular hormone. See also attention deficit hyperactivity disorder (ADHD).

Alternative Names:
Activity - increased; Hyperkinetic behavior

Considerations:

Hyperactive behavior commonly refers to a group of characteristics. This can include constant activity, easy distractibility, impulsiveness, inability to concentrate, aggressiveness, and similar behaviors.

Typical behaviors may include fidgeting or constant moving, wandering, excessive talking, and difficulty participating in quiet activities (such as reading).

Hyperactivity is not easily defined, because it often depends on the tolerance of the observer. Behavior that seems excessive to one observer may not seem excessive to another. However, certain children -- when compared to others -- are clearly far more active, which can become a problem if it interferes with school work or making friends.

Hyperactivity is often considered more of a problem for schools and parents than it is for the affected child. However, many hyperactive children are unhappy or even depressed. Hyperactive behavior may make a child a target for bullying, or make it harder to connect with other children. Schoolwork may be more difficult, and hyperactive kids are frequently punished for their behavior.

Hyperkinetic behavior often decreases as the child grows older, and may disappear entirely by adolescence.
