Patient’s suffering from Headaches (migraines, chronic daily headaches, tension type headaches) can also be affected by TMJ Disorder (TMD).
The definition of Comorbid is: existing simultaneously with and usually independently of another medical condition (http://www.merriam-webster.com/dictionary/comorbid)
There are several comorbidities that increase the risk of headaches:
(a) TMJ Disorders (TMD)
(c) Sleep Apnea
(d) Other: Obesity, Stressful life events, Psychiatric comorbidity
Individuals with TMJ Disorders were more likely to have migraines, chronic daily headaches and tension type headaches as compared to individuals without TMJ Disorder symptoms according to Dr. Gonçalves large study of 1,230 individuals who were surveyed for the comorbidity of headaches (migraines, chronic daily headaches and tension type headaches).
Temporomandibular disorders and headaches should be treated together but seperately according to Dr. Graff-Radford (Director of the Program for Headache and Orofacial Pain at the Pain Center at Cedars-Sinai) and Dr. JP Bassiur (Director of the Center for Oral, Facial, and Head Pain at the Columbia University Headache Center). According to their article they wrote “If there is marked limitation of opening, imaging of the joint may be necessary. The treatment should then include education regarding limiting jaw function, appliance therapy, instruction in jaw posture, and stretching exercises, as well as medications to reduce inflammation and relax the muscles. The use of physical therapies, such as spray and stretch and trigger point injections, is helpful if there is myofascial pain.”
The AMPP (American Migraine Prevalence and Prevention) did a study on the 1-year evolution of migraine. The results showed that over a 1 year period:
(a) 84% still had migraine
(b) 10% had 1-year complete clinical remission
(c) 3% had partial remission,
(d) 3% developed chronic migraines (15 or more days per month)
