Pediatric cerebral palsy (pediatric cerebral palsy) is a non-progressive brain injury caused by various causes during the perinatal period. Cerebral palsy mainly manifests as central motor disorders and postural abnormalities, which may be accompanied by intellectual developmental disorders, epilepsy, behavioral abnormalities or perceptual disorders, and language disorders, etc. Symptoms mostly appear within 1 year of age, and it is a more common and severely disabling disease in pediatric period, with an incidence of about 1.5~5‰, accounting for the first place of pediatric neurological and genetic consultation outpatient visits. Characteristics of cerebral palsy: Developmental: It refers to the damage sustained during the growth and development of brain tissue. Non-progressive: The lesions of cerebral palsy are non-progressive and the condition is characterized by no further forward progression. Permanent: Cerebral palsy is not a transient disorder, but a permanently present central motor dysfunction disorder. Cerebral palsy: Cerebral palsy is a disease in which the brain has been damaged by a certain cause, and although the lesion no longer progresses, it causes the development of movement and posture to progress to abnormal aspects, and even complications such as damage to intelligence and language. They are unable to communicate with others normally. Individuals with epilepsy, hearing loss, visual abnormalities (strabismus, amblyopia, visual field loss), etc. are also affected. Cerebral palsy is mainly diagnosed clinically, and there is no specific diagnostic index. Our 1988 conference on pediatric cerebral palsy formulated three diagnostic criteria: 1. central palsy appearing during infancy; 2. it may be accompanied by mental retardation, convulsions, behavioral abnormalities, perceptual disturbances and other abnormalities; 3. it is necessary to exclude central palsy caused by progressive diseases and transient motor developmental backwardness in normal children. The clinical manifestations of cerebral palsy are highly suggestive: 1. Premature infants, low weight infants, severe hypoxia at birth and in the neonatal period, convulsions, intracranial hemorrhage and nuclear jaundice; 2. Mental retardation, emotional instability and easy panic. The typical manifestations of delayed motor development, increased muscle tone and spasticity; attention should be paid to differentiate from the following diseases: 1. hereditary spastic paraplegia; 2. ataxia capillaris; 3. sequelae of encephalitis.
