Recurrent Headache in Young May Be Tied to Vitamin D Deficiency

Article excerpt

LOS ANGELES -- Vitamin D deficiency was detected in 37% of 497 children and adolescents presenting to a tertiary care center for recurrent headache that required preventive treatment. Vitamin D insufficiency was found in 87%.

These results of routinely measuring baseline serum 25-hydroxyvitamin D (25[OH]D) levels at new patient visits or at follow-up visits suggest that pediatric patients with recurrent headaches may be at increased risk for vitamin D insufficiency or deficiency compared with the general healthy population, Dr. Hope L. O'Brien and her associates reported in a poster presentation at the meeting.

Vitamin D deficiency was defined as a serum 25(OH)D level of less than 20 ng/mL. Vitamin D insufficiency was defined as a level below 30 ng/mL.

Serum 25(OH)D levels averaged 24 ng/mL in patients presenting with episodic migraine and 23 ng/mL in patients presenting with chronic migraine, reported Dr. O'Brien of the University of Cincinnati.

Studies have suggested a link between low vitamin D levels and migraine or chronic tension-type headache in adults, but this may be the first study to assess this association in children and adolescents. …
