High prevalence of vitamin D deficiency among those who Suffer from Cluster Headaches: Cluster headache is a type of neurological disorder that causes severe pain on one side of the head, usually centered behind one eye.
During a cluster headache, individuals often experience agitation, flushing, or sweating of the face and redness and discharge of the eyes and nose. The pain usually lasts 30-60 minutes and recurs several times a day for weeks to months at a time.
Interestingly, about 80% of cluster headache sufferers experience a marked increase in headaches during seasonal changes. Since vitamin D levels vary between seasons, researchers hypothesize that vitamin D may play a role in cluster headaches.
Vitamin D and Cluster Headaches
In a new case-control study, researchers evaluated vitamin D levels among 28 patients with cluster headaches, 36 individuals with migraines, and 36 healthy controls.
From October of 2016 to March of 2018, the participants had their serum 25(OH)D levels measured, along with the seasons in which these levels were obtained.
Average vitamin D levels among patients with cluster headache was 14 ng/ml. A total of 92.8% of these individuals had vitamin D levels < 20ng/ml, and none of the cluster headache sufferers had 25(OH)D levels above 30 ng/ml.
The researchers stated:
“In summary, this is the first report to examine serum vitamin D levels in patients with [cluster headache] compared to those of age-and sex-matched controls controlling for sampling season as well as other clinical variables.”
Past research has shown that vitamin D deficiency is associated with increased frequency and severity of tension headaches. In addition, vitamin D supplementation has been shown to help treat migraines.
However, more research needs to be conducted to determine whether vitamin D supplementation may reduce cluster headache duration or severity.
Based on the evidence to date, the Vitamin D Council recommends adults who suffer from chronic headaches supplement with between 5,000-10,000 IU vitamin D3 per day in order to achieve healthy vitamin D status (40-80 ng/ml).
