Abstract

Background: Inconsistent results have been obtained with regard to headache comorbidity in multiple sclerosis (MS).

Objective: Investigate the one-year prevalence of migraine and tension-type headache (TTH) in Norwegian MS patients and relate this to clinical parameters.

Methods: A questionnaire concerning headache was administered to 756 MS patients and 1090 controls and used to determine the one-year prevalence of migraine and frequent TTH.

Results: No significant differences were seen between patients and controls or between patients with different disease course. Less migraine was observed in patients with Expanded Disability Status Scale score (EDSS) ≥4.0.

Conclusions: This case-control study does not support an association between migraine or TTH and MS.

Keywords: Multiple sclerosis; case-control study; migraine; tension-type headache.
