Clinical characterization of delayed alcohol-induced headache: A study of 1,108 participants

Abstract

Objective: To evaluate the International Classification of Headache Disorders (ICHD) criteria and to characterize the clinical phenotype of delayed alcohol-induced headache (DAIH).

Methods: We conducted a cross-sectional study of university students who voluntarily consumed alcohol and experienced headache. Participants completed a survey that included demographic and clinical data. We analyzed the phenotype of the headache, validated ICHD phenotype criteria for DAIH, and analyzed whether participants fulfilled criteria for low-CSF-pressure headache or migraine.

Results: A total of 1,108 participants were included (58% female, mean age 23 years, 41% with headache history). Mean alcohol intake was 158 g; spirits were consumed by 60% of the participants; beer was consumed by 41%; and wine was consumed by 18%. The ICHD criteria for DAIH were met in 95% of the participants. Headache duration (mean, 6.7 hours) correlated with total grams of alcohol consumed (r = 0.62, p = 0.03). Pain was bilateral in 85% of patients with predominantly frontal topography (43%). Pain quality was mainly pressing (60%) or pulsatile (39%) and was aggravated by physical activity in 83% of participants. ICHD low-CSF pressure-headache criteria were fulfilled in 58% of patients, and migraine criteria were fulfilled by 36%.

Conclusions: DAIH is a moderate-intensity headache, is typically bilateral, and presents with frontal predominance and a pressing quality. The phenotype of DAIH combines features of both migraine and low-CSF-pressure headaches.
