Among the patients who present with clinical signs of seizure, the EEG is the most efficient test for diagnosis.
Video-EEG monitoring is a combination of recording EEG and clinical behavior of the patient. Although it's more expensive, it is more effective in differentiating different type if seizures.[2]
With the first seizure, in order to reach a diagnosis and find out the etiology of seizure, we should perform ancillary testing such as:[1][3][4]
