Clinical characterization of delayed alcohol-induced headache

Abstract

<h3>Objective</h3> To evaluate the International Classification of Headache Disorders (ICHD) criteria and to characterize the clinical phenotype of delayed alcohol-induced headache (DAIH). <h3>Methods</h3> 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. <h3>Results</h3> 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 (<i>r</i> = 0.62, <i>p</i> = 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%. <h3>Conclusions</h3> 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.
