Epilepsy is a common disease in neurology and includes many types, generally including primary epilepsy and secondary epilepsy. Primary epilepsy refers to cases where the cause is unknown, while secondary epilepsy has a clear cause. Common causes include developmental disorders of the cerebral cortex, tumors, and cerebrovascular diseases, traumatic brain injuries, and central nervous system infections, including encephalitis, meningitis. Cerebrovascular diseases such as cerebral hemorrhage and cerebral infarction can also induce epilepsy. Additionally, certain neurodegenerative diseases, such as motor neuron disease and late-stage Parkinson's disease can also trigger epileptic seizures. Patients with ischemic hypoxic encephalopathy and toxic encephalopathy may also experience epileptic seizures, and some systemic diseases may also lead to epileptic seizures.
