Harmful factors of fetal brain dysplasia during pregnancy: harmful factors during pregnancy, such as rubella virus, giant nerve factor virus, Toxoplasma gondii virus during pregnancy, or factors such as high fever, toxemia, hypoxia and shock affect fetal development; Abnormal fetal position, prolonged labor, severe cleavage and contraction, umbilical cord knotting or around the neck, amniotic fluid inhalation, birth injury, asphyxia and other brain factors can all induce brain dysplasia. Environmental factors: the mother's own environment may affect the mother's fetus, such as the mother suffering from diabetes, and the fetus is affected by its internal environment, leading to congenital heart disease or anencephaly; The mother suffers from hypothyroidism, and the fetus is prone to bone and tooth deformities, cryptorchidism, tongue coating dementia, goiter and so on. This is also a major cause of brain dysplasia. Nutritional factors: early malnutrition can shorten the division period of brain nerve factors, and late malnutrition can reduce the volume of brain nerve factors. If malnutrition occurs in the early stage, especially in the fetal period, although the nutrition has improved after birth, the mental recovery is still slow or difficult to recover, which will lead to brain dysplasia.
Childhood epilepsy 1. Birth injury: it is a common cause of symptomatic epilepsy in infants. The causes of birth injury include forceps delivery, fetal head attraction, head-basin asymmetry, abnormal fetal position, too large fetus, too long labor process, too old primipara, too tight birth canal and so on.
2. Congenital factors: Congenital diseases such as brain malformation, hydrocephalus and chromosomal abnormality, as well as the damage of the fetus in the mother's body before birth, can cause abnormal development and seizures after birth, such as abdominal injury of pregnant women, uterine bleeding, ultraviolet radiation, taking drugs harmful to the fetus, and various microorganisms, especially rubella, measles virus and Toxoplasma infection.
3. Brain diseases: After patients with brain hypoplasia, brain retardation, brain atrophy, various encephalitis, meningitis and brain abscess recover, some people may have epilepsy; Cerebral schistosomiasis and cysticercosis can cause epilepsy.
4, amniotic fluid inhalation fetal asphyxia, umbilical cord around the neck, placental abruption, placenta previa, umbilical cord prolapse, caesarean section and so on. After that, the incidence rate increased significantly.
5. Poisoning: lead, gas, pesticides and systemic diseases such as hepatic encephalopathy, acute nephritis and uremia can all cause seizures.
6, nutritional metabolic diseases: hypoglycemia, diabetic coma, vitamin B6 deficiency, hyperthyroidism and so on. Can cause epilepsy.
Trauma and low immunity: trauma and some babies often catch a cold and have a fever, which sometimes causes epilepsy.
8. Genetic factors: 5% of children with epilepsy have epilepsy.
