People with epilepsy could also be classified into different syndromes supported specific clinical features. These features include the age at which seizures begin, the seizure types, and EEG findings, among others. Identifying an epilepsy syndrome is beneficial because it helps determine the underlying causes also as deciding what anti-seizure medication should be tried. Epilepsy syndromes are more commonly diagnosed in infants and youngsters. Some samples of epilepsy syndromes include benign rolandic epilepsy (2.8 per 100,000), childhood absence epilepsy (0.8 per 100,000) and juvenile myoclonic epilepsy (0.7 per 100,000). Severe syndromes with diffuse brain dysfunction caused, a minimum of partly, by some aspect of epilepsy, also are mentioned as epileptic encephalopathies. These are related to frequent seizures that are immune to treatment and severe cognitive dysfunction, as an example Lennox-Gastaut syndrome and West syndrome.
