Correlation between essential tremor and migraine headache

Abstract

The relationship between essential tremor (ET) and migraine was investigated in a prospective study. In a group of 74 ET patients 36-5% had migraine compared with 17-7% of 102 control subjects without tremor. In a group of 58 patients with migraine 17-2% had ET compared with 1-2% of 85 controls without migraine. The prevalence of ET in migraine controls was greater than controls without migraine (22% compared with 1%; p = 0 002). It is concluded that there is an association between essential tremor and migraine.
