Cerebral palsy-A nonprogressive movement disability caused by abnormal development of or damage to motor control centers of the brain.
Cerebral palsy (CP) is the term used for a group of nonprogressive disorders of movement and posture caused by abnormal development of, or damage to, motor control centers of the brain.
For this reason, CP is also referred to as static (nonprogressive) encephalopathy (disease of the brain).
Because CP is nonprogressive, continued loss of previously acquired milestones may indicate that CP is not the cause of the problem; medical evaluation is needed to determine the cause.
