Overview
Electroencephalogram
An ECG may be helpful in the diagnosis of epilepsy. Findings on an EEG suggestive of epilepsy include:[1]
| Epilepsy | |||||||||||||||||||||||||||||||||||||||||||||||
| Generalized | Focal | ||||||||||||||||||||||||||||||||||||||||||||||
| Tonic–Clonic Seizures | Absences | Focal Seizures without Altered Consciousness | Focal Seizures with Altered Consciousness | ||||||||||||||||||||||||||||||||||||||||||||
| synchronous generalized spikes and waves in all leads | bursts of synchronous, generalized
spike-and-wave activity at a frequency of approximately 3 Hz | localized epileptic activity over the seizure focus | temporal slow waves or spikes. In the interictal period/Normal EGG | ||||||||||||||||||||||||||||||||||||||||||||
NOTE: Video-EEG monitoring is a combination of recording EEG and clinical behavior of the patient. Although, it's it's more expensive, it is more effective in differentiating different type if seizures.[2]
