Epilepsy may be caused by diseases, heredity and irregular use of epilepsy drugs. 1. Diseases: For example, brain developmental abnormalities, brain tumors, trauma, central system infections, cerebrovascular diseases and other brain or systemic diseases can cause brain dysfunction, which can lead to epilepsy. 2. Heredity: Epilepsy can be passed on to the next generation through genetic inheritance, and usually occurs in conjunction with environmental and personal experiences. 3. Irregular use of epilepsy medication: epilepsy can be triggered if a person with epilepsy misses a dose of medication, reduces the medication on his or her own, stops taking the medication, or changes the medication. It is recommended that patients with epilepsy, go to the hospital in time, under the guidance of the doctor for reasonable treatment.
