1, congenital diseases Can be caused by some congenital genetic diseases, such as gastric cancer8, cerebral facial hemangioma, neurofibromatosis, etc. Having lesions in the brain can cause seizures. These diseases often have abnormal pigmentation spots or hemangiomas in the skin. 2, the condition of pregnant women during pregnancy The mother is infected with rubella, cytomegalovirus, herpes virus, or other bacterial infections during pregnancy, especially early pregnancy, and the fetus is affected in utero; exposure of pregnant women to large amounts of radiation exposure or poisoning can also cause abnormal development of the fetal nervous system, such as cerebral gyrus malformation, corpus callosum agenesis, and gray matter ectopia, resulting in secondary epilepsy in children. The birth of a child with birth injuries, severe asphyxia, intracranial hemorrhage, and forceps assisted delivery may cause brain damage that can lead to secondary pediatric epilepsy. 4, children suffering from various brain diseases After birth, various kinds of encephalitis and meningitis, although cured in the acute stage, after a period of time, may also appear seizures; brain parasitic diseases such as cerebral cysticercosis, cerebral pulmonary schistosomiasis, cerebral schistosomiasis can cause secondary epilepsy in children; due to the consumption of pork, vegetables or food contaminated with tapeworm eggs that are not fully cooked, cysticercus parasites in the brain, resulting in secondary epilepsy in children. secondary epilepsy. 5. Traumatic brain injury in children Traumatic brain injury is a common cause of epilepsy, but usually falling and touching the scalp or falling out of bed at night does not cause secondary epileptic seizures in children. The more severe the injury, the greater the likelihood of secondary epilepsy occurring in children. There is no relationship between the length of coma after trauma and the incidence of pediatric secondary epilepsy, and open cranial injuries have a greater chance of occurring than closed injuries. If the traumatic brain injury is combined with cerebrovascular disease 6, intracranial hemorrhage, or skull depression fracture, the chance of the disorder is greater.
