ABSTRACT
Epilepsy is a clinical diagnosis. Besides clinical data, EEG (electroencephalography) is the most important diagnostic tool in the diagnosis of epilepsy. The correct evaluation of epileptiform discharges in EEG is crucial. Generalized epileptiform discharges ocur synchronously and symmetrically in both hemispheres. Ictal and interictal activities in generalized epilepsies are multiple spikes, multiple spike and slow waves, spike or sharp and slow waves, irregular spikes or sharp waves and hypsarrhythmia. In this review, interictal and ictal EEG findings of absence epilepsy, generalized tonic clonic seizures, myoclonic seizures, infantile spasm and tonic seizures will be described with clinical cases and EEG samples.
Keywords: Electroencephalography; epilepsy, generalized
