PURPOSE: 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.
METHODS: In this cross-sectional study, a total of 100 patients, 50 patients each of migraine and tension-type headache attending the neurology OPD and fulfilling the diagnostic criteria of headache disorders were enrolled. Autonomic functions tests were performed in the Department of Physiology, whereas electrophysiological tests were powered by the Editorial Manager and ProduXion Manager from Aries Systems Corporation performed in the Department of Neurology.
RESULTS: Significant association ( P < 0.05) was observed in "blood pressure response to sustained handgrip" (sympathetic activity) and "heart rate response to Valsalva maneuver" (parasympathetic activity) among patients with migraine. Although the mean sympathetic skin response latency of patients with migraine was within the normal range, it was significantly prolonged in comparison with the control group. "Blood pressure response to sustained handgrip" and "heart rate variability" were found to be significantly ( P < 0.05) different in patients with a tension-type headache. The blink reflex test was observed to be normal in all patients with a headache. Patients with migraine showed a significant dysautonomia in category three of the Ewing battery for autonomic functional disability.
CONCLUSIONS: Autonomic functional abnormality, both sympathetic and parasympathetic, does exist in patients with a primary episodic headache.
