Cerebral palsy is a group of persistent central motor and postural developmental disorders and activity limitation syndromes that result from non-progressive brain damage in the developing fetus or infant. The motor deficits of cerebral palsy are often accompanied by sensory, perceptual, cognitive, communication, and behavioral deficits, as well as musculoskeletal problems secondary to epilepsy. Cerebral palsy may be accompanied by one or more other dysfunctions and comorbidities, most commonly mental retardation, epilepsy, speech impairment, visual impairment, auditory impairment, swallowing impairment, and behavioral abnormalities, as well as secondary injuries such as muscle atrophy, contractures, and deformities or dislocations of bones and joints.
