The written history of epilepsy goes back 3000 years with not only is identifying an increasing number of “epilepsy accurate descriptions of epileptic phenomena appearing in genes” responsible for specific types of epilepsy, and further the writings of ancient Mesopotamia and the Indian Ayurvedic characterizing genetic disorders associated with epilepsy, but texts. Although physicians of the Hippocratic school in Greece, also advancing the concept of susceptibility genes, which will about 400 BC, understood that epileptic seizures originated in explain variable individual predispositions to develop certain the brain, as did Galen several hundred years later, epilepsy forms of acquired epilepsies.

At that time, the nascent disciplines of basic Methodology for characterizing different types of epileptic neuroscience and clinical neurology defined a variety of ictal seizures and the disorders associated with them, particularly manifestations, including focal seizures and absences, and through electroclinical correlations, that is the association of recognized them as part of a constellation of disorders referred particular behavioral ictal signs and symptoms with their to as epilepsy.
