I L D Hyperactivity in Childhood.
Most children are normally active.
Physical and psychological activity are necessary for the development of healthy individuals. However, a hyperactive child impedes his or her own development by not concentrating on school work, play or discipline. Hyperactivity in children may be difficult to diagnose and often requires the keen eye of a trained observer. However, parents may notice marked differences between different children in the same family and comment on their activity. Teachers are often the first to notice hyperactive pupils and bring this to the attention of parents.
