Cranial autonomic symptoms are typically associated with the trigeminal autonomic cephalalgias and also present in substantial cases of migraine. Autonomic nervous system dysfunctions are also been reported in headache disorders and postulated to promote headache attacks. This study was aimed to evaluate the parasympathetic and sympathetic autonomic functions tests in patients with a episodic primary headache and to investigate, if any, electrophysiological abnormalities in the blink reflex test and sympathetic skin response test in these patients.
