Hyperactivity

Hyperactivity can be described as a state in which a person is abnormally easily excitable and exuberant. Strong emotional reactions and a very short span of attention is 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 serious and harmful to the person as well as others, it may be classified as a medical disorder.
