Hyperactivity can be described as a physical state in which a person is abnormally and easily excitable or exuberant. Strong emotional reactions, impulsive behavior, and sometimes a short span of attention are also typical for a hyperactive person. Some individuals may show these characteristics naturally, as personality differs from person to person. Nonetheless, when hyperactivity starts to become a problem for the person or others, it may be classified as a medical disorder. The slang term "hyper" is used to describe someone who is in a hyperactive state.
