There are a variety of reasons why you can suddenly get epilepsy, including genetics, head trauma, cortical developmental disorders, and central nervous system infections. 1. Heredity: Having two parents with epilepsy may lead to an increased chance of getting epilepsy, and may cause epilepsy during adolescent development or in adulthood. 2. Head trauma: head trauma can easily cause cerebral contusion and intracranial hematoma, and may also cause skull fracture or cranial nerve injury, which may induce epilepsy. 3. Cortical dysplasia: most focal cortical dysplasia will cause abnormal development of the body’s cytology and cortical structure, and the presence of abnormal neurons may induce epilepsy. 4. Central nervous system infections: usually due to viral encephalitis or tuberculous meningitis, human immunodeficiency virus infections may cause metabolic disorders and demyelinating infections in the central nervous system, which may cause epilepsy. If symptoms of epilepsy appear, it is recommended to seek medical treatment as soon as possible, standardized diagnosis and treatment under the guidance of professional physicians, and regular oral antiepileptic drug treatment in accordance with the doctor’s instructions, so as to avoid delaying the condition.
