Migraine and Alcohol-Is It Really That Harmful?

Alcohol is a widely consumed beverage worldwide, and headaches, including migraine, tension-type headache (TTH), and other primary headaches, are common in the general population. Although epidemiological studies have shown a correlation between alcohol consumption and headaches, the specific pathophysiological mechanism of this headache remains unknown. We reviewed articles deemed relevant to the issue of alcohol as a trigger for various headaches, those that discussed alcohol consumption in these patient groups, and those that addressed the pathophysiological and clinical aspects of alcohol and headache. The review concluded that alcohol affects both migraine and non-migraine headaches. Alcohol-induced headache, classified as a secondary headache, is a throbbing, bilateral headache that is exacerbated by physical activity and is precipitated by alcohol consumption. TTH can be precipitated by alcohol consumption, and patients with TTH have more alcohol-related problems than those with migraine. Cluster headaches (CH) are often triggered by alcohol, but surprisingly, many CH patients consume alcohol, even during attacks. The relationship between alcohol and migraine is complex. Numerous components of alcoholic beverages can influence pain triggering and are responsible for migraine attacks. Red wine is one of the most frequently cited triggers for migraine attacks, a finding not always confirmed by the few prospective studies. However, there is no safe dose of alcohol, and therefore avoidance should be recommended.
