Hypothyroidism and Headache
Hypothyroidism has been found to be associated with chronic daily headache* in both the varieties of chronic migraine and new daily persistent headache. In one study, 30% of individuals with hypothyroidism had developed mild daily headache within 1-2 months of onset of the thyroid disorder. A history of migraine predisposed to the development of headache.
Hashimoto's Disease, an autoimmune form of chronic thyroiditis, has also been associated with increased likelihood of headache.
A study of white matter hyperintensities seen on MRI in migraine found that either hypothyroidism or hyperthyroidism (too low or too high) was associated with these MRI abnormalities.
* This was chronic migraine without any evidence of medication overuse.
