1.Prenatal factors: causes within the first six months of pregnancy: congenital malformations, hereditary defects, intrauterine infections, cerebral hypoxia due to pre-eclampsia, rubella infection, toxic exposure, radioactive material radiation or medicine. 2, intrapartum factors: fetal hypoxia during delivery, obstructed labor, neonatal asphyxia, giant babies, postnatal respiratory failure, premature and immature babies, birth injuries, low birth weight babies. 3. Postnatal factors: nuclear jaundice, neonatal shock, craniocerebral injury and seizures, respiratory obstruction in immature infants, and cerebral hypoxia caused by pulmonary ventilation dysfunction. Hyperbilirubinemia, convulsions and severe asphyxia in the neonatal period. During the course of pregnancy, “supplementation” is an indispensable nutritional saving step, which not only ensures the health of the mother’s body functions, but also maintains the nutritional needs of the fetus. But in the process of food supplementation, must require a comprehensive, especially focus on the regular intake of trace elements, because trace elements, especially essential trace elements play an important role in ensuring embryonic development, maintaining human growth and normal metabolism. 4, the causes of pregnant women: including abdominal trauma to pregnant women, pregnant women with preterm abortion, prenatal hemorrhage, pregnancy toxemia and placental causes, as well as certain chronic diseases of pregnant women. 5, Genetic factors: It is thought that cerebral palsy can be traced back to a family history of hereditary disease. 6, Intoxication: Etiology in the later stages of pregnancy: toxemia of pregnancy, placental or umbilical cord abnormalities, prenatal hemorrhage, blood group incompatibility, trauma to the mother, infection or multiple pregnancies. 7. Parental smoking, alcoholism, drug addiction mother illnesses, etc.: mental illness, diabetes mellitus during pregnancy, vaginal bleeding gestational hypertension syndrome, pre-eclampsia or taking contraceptives for infertility, birth control drugs, etc.; 8. Acquired causes: refers to the manifestation of cerebral palsy in children with pediatric cerebral palsy more than one month after birth due to certain diseases that damage brain tissue. For example: cerebral artery embolism, intracranial abscess, meningitis, etc.
