People who suffer from headaches are three times more likely to suffer from severe jawbone disorder, a study has found.

Researchers from University of Sao Paulo in Brazil found that the more frequent the attacks, the more severe will be the affecting the jaw joint.


TMD may increase the frequency and severity of attacks, even though it does not directly cause migraine, researchers said.

"is a neurological disease with multifactorial causes, whereas TMD, like cervicalgia - neck pain - and other musculoskeletal disorders, is a series of factors that intensify the sensitivity of sufferers," said Lidiane Florencio, researcher at the University of Sao Paulo.

"Having TMD may worsen one's attacks in terms of both severity and frequency," said Florencio.

Previous studies indicated that is somehow associated with pain in the chewing muscles.

The temporomandibular joint acts like a sliding hinge connecting the jawbone to the skull, therefore the disorder's symptoms includes difficulty chewing and joint tension, researchers said.

TMD can be considered a potential perpetuating factor for because it acts as a constant nociceptive input that contributes to maintaining central sensitisation and abnormal pain processes, they said.

"The repetition of attacks may increase sensitivity to pain," Florencio said.

Researchers assessed 84 women in their early to mid- thirties, 21 were patients, 32 had episodic migraine, while 32 with no history of were included as controls.

Signs and symptoms of TMD were observed in 54 per cent of the control participants without migraine, 80 per cent of participants with episodic migraine, and 100 per cent of those with

The study was published in the Journal of Manipulative and Physiological Therapeutics.
