Objectives: Headache is one of the most common neurological disorders around the world. Previous studies have proposed associations of food allergies with headaches. Therefore, this study evaluated the frequency of sensitization to food allergens in patients with migraine and tension headaches and their correlations with these disorders.
Methods: The study subjects consisted of 20 patients with migraine headache and 20 subjects with tension headache. Headache disorders were confirmed by a specialist. Food allergen sensitization was diagnosed by skin prick test (SPT) or radioallergosorbent test (RAST), clinical history, and physical examination.
Results: There was no significant difference in age and gender between patients with migraine and tension headaches. Other results showed sensitization to food allergens, such as egg, wheat, fish, banana, orange, and soybean, in patients with migraine headache was similar to those in subjects with tension headache. However, patients with migraine headache significantly differed from individuals with tension headache in allergic responses to tree nut (P=0.047), peanut (P=0.028), and cow's milk (P=0.044).
Conclusion: The results of this study showed that sensitization to food allergens may relate to migraine headache which their diagnosis can help to better control and manage the disease.
Keywords: Food allergen sensitization; migraine headache; tension headache.
