Alcohol and migraine: what should we tell patients?

Alcoholic drinks are a migraine trigger in about one third of patients with migraine in retrospective studies on trigger factors. Many population studies show that patients with migraine consume alcohol in a smaller percentage than the general population. Moreover, research has shown a decreased prevalence of headache with increasing number of alcohol units consumed. The classification criteria of alcohol-related headaches remain problematic. We discuss the role and mechanism of action of alcohol or other components of alcoholic drinks in relation to alcohol-induced headache. In accordance with data from a recent prospective study, we believe that reports overestimate the role of alcohol, as well as other foods, in the triggering of migraine. If a relationship between the intake of alcohol and the migraine attack is not clear, a small dose of alcohol is not contraindicated either for enjoyment or its protective effect on cardiovascular disease.
