Comorbidity of Temporomandibular Disorders, Anxiety, Depression, and Poor Sleep Quality in Episodic and Chronic Migraine: A Cross-Sectional Observational Study.

This study looked at the link between temporomandibular disorders (TMD) and migraine. Researchers focused on two types of migraine: episodic migraine (EM) and chronic migraine (CM). They wanted to see if TMD made migraine symptoms worse. The study involved 120 participants, including 40 without headaches, 40 with EM, and 40 with CM. Researchers gathered information through structured interviews. Participants filled out several questionnaires to assess headache impact, anxiety, depression, and sleep quality. They found that TMD was more common in migraine patients. Those with TMD experienced more severe headaches, higher medication use, and worse anxiety and depression. Additionally, sleep quality was poorer among those with TMD. This suggests that TMD may be an important factor in understanding and treating migraines, especially for patients experiencing more severe symptoms or psychological distress. Clinical relevance: This study highlights the need for comprehensive evaluations of migraine patients, considering TMD, anxiety, and sleep quality for better treatment outcomes.
