In a recent study, researchers found that patients with chronic migraines which usually occur for more than 15 days a month are likely to experience three times more severe symptoms of Temporomandibular disorder (TMD) than patients with an episodic migraine.
"Migraine patients are more likely to have signs and symptoms of TMD, but the reverse is not true. There are cases of patients with severe TMD who don't present with migraine," said Dedora Grossi, lead author of the study and principal investigator for the project. The TMD may increase the frequency and severity of migraine attacks though it does not directly cause migraine, said researchers."Our findings show the association with TMD exists but is less frequent in patients with rare or episodic migraine," said Grossi.
"This information alone should change the way clinicians examine patients with migraine. If migraine sufferers tend to have more severe TMD, then health professionals should assess such patients specifically in terms of possible signs and symptoms of TMD, " she explained.
A migraine is a neurological disease which gets triggered with genetic and environmental factors, whereas temporomandibular disorder includes series of factors that magnify the sensitivity of migraine attacks. Suffering from the TMD on top of migraine may worsen the migraine attacks in terms of both severity and frequency, shows the study.
