hereditary factor
In recent years, studies have shown that genetic factors play an increasingly important role in cerebral palsy. For example, close relatives with epilepsy, cerebral palsy and mental retardation account for 65% of cerebral palsy.
Birth factor
It is related to premature delivery, overdue delivery, multiple births, low weight, asphyxia, birth injury and hypoxic-ischemic encephalopathy.
acquired disposition
It is related to infection, trauma, intracranial hemorrhage and bilirubin encephalopathy.
Perinatal factors
Refers to the brain injury that occurs within one week after delivery, including brain edema, neonatal shock, cerebral hemorrhage, sepsis or central nervous system infection, ischemic and hypoxic encephalopathy, etc.
heterauxesis
53% of patients with cerebral palsy and quadriplegia are related to abnormal fetal development; Among the patients with cerebral palsy who are not quadriplegic, 20% are caused by congenital dysplasia.
Hypoxia/anoxia
Long-term ischemia and hypoxia of brain tissue: Among children with cerebral palsy, 20% are caused by asphyxia and birth injury.
