[Symptomatic Epilepsy].

The notion of symptomatic epilepsy was historically reviewed. The structural etiologies of epilepsy include cerebrovascular diseases, neurodegenerative diseases, neoplasms, and traumatic brain injuries. Infections are the most common etiology worldwide. Metabolic epilepsy directly results from a known or presumed metabolic disorder. Immune epilepsy occurs because of autoimmune-mediated central nervous system inflammation.
