Cerebral palsy is a syndrome of morbid disablement or traumatic maim of central nervous system commonly seen in fetuses and infants. Many factors (such as infection, hemorrhage and trauma) may cause cerebral parenchymatous injury. In this case, nonprogressive and central dyskinesia occurs, giving rise to the disease. In severe cases, the disease is complicated by mental deficiency, epilepsy, clonic convulsion of limbs as well as visual, auditory and verbal dysfunctions. The main sites of pathological changes lie in the brain and pyramidal tract. The disease may be discovered in most infantile patients after birth or during infancy. In recent years, the incidence of the disease is lower than that of the past with the continuous development of medical science, the extensive publicity of eugenics and the active implementation of perinatal health care.
