There has long been as association between migraine headaches and vascular (blood vessel) dysfunction of some kind, underscored by epidemiological studies and other research. New evidence for a genetic connection now comes from the analysis of several large data sets of each condition based on Genome Wide Association Studies (GWAS).

The Washington Post recently featured an article on Temporomandibular Disorders. Below is an excerpt from that article and a link to the full story.
