Answer

Answer

Electroencephalography is not useful in the routine evaluation of headache patients. Reserve it for patients with an atypical migraine aura, episodic loss of consciousness, or symptoms suggestive of a seizure disorder. Focal or diffuse background slowing can be seen during a migraine headache, particularly hemiplegic or confusional migraine; however, electroencephalography results are often normal.
