Summary
Epilepsy syndromes (electroclinical syndromes) are well-recognized groupings of clinical (seizure types) and EEG features that occur together. Each syndrome typically shares a common age of onset, deficits (intellectual dysfunction), treatment and prognosis. Syndromes are classified based on their onset, epilepsy type (focal, generalized, or mixed) and development of epileptic encephalopathy (disorder in which epileptic activity contributes to severe impairments in cognition and behavior). Relatively benign syndromes are typically associated with focal, generalized tonic-clonic (GTC), typical absences and myoclonic seizures. Epileptic encephalopathies are typically associated with atonic, tonic, atypical absences, and epileptic spasms in addition to the other seizure types. [106 words/729 characters]
