Many causes can cause epilepsy, especially lesions of the cerebral cortex, which are generally considered to be related to the following four factors: 1. genetic factors: epilepsy is likely to occur in families of patients with a history of epilepsy or congenital central nervous system or heart malformations; 2. brain damage and brain injury: embryonic dysplasia caused by viral infection radiation exposure or other causes during embryonic development can cause epilepsy; 3. The fetal birth injury is also a major cause of epilepsy; cranio-cerebral trauma can also cause epilepsy; 3, other diseases of the cranial brain: brain tumors, cerebrovascular disease, intracranial infections, etc.; 4, environmental factors: male patients have a slightly higher incidence than female patients in rural areas than in urban areas.
