Comorbidity of Temporomandibular Disorders with Episodic and Chronic Migraine Is Not Linked to Anxiety, Depression, or Poor Sleep Quality
Abstract
Background: : /Objectives: This study investigated the comorbidity between temporomandibular disorders (TMD) and migraine, distinguishing episodic migraine (EM) from chronic migraine (CM), and examined whether TMD presence in migraine patients is associated with more severe clinical or psychological features.
Methods:: A cross-sectional sample of 120 participants was evaluated, including 40 headache-free controls, 40 EM patients, and 40 CM patients. Demographic and clinical information was obtained through structured interviews. Participants completed the Headache Impact Test (HIT-6), State-Trait Anxiety Inventory (STAI), State-Trait Depression Questionnaire (ST-DEP), and Pittsburgh Sleep Quality Index (PSQI). Prevalence ratios (PR) analyzed the association between TMD and migraine and between TMD and migraine subtypes. Among migraine patients, headache frequency, medication use, headache impact, anxiety/depression symptoms, and sleep quality were compared between those with and without TMD.
Results:: TMD was significantly more common in migraine patients compared to controls (78.8% vs. 20.0%; PR = 3.94; 95% CI: 2.10–7.40). CM patients also showed a higher TMD prevalence than EM patients (95.0% vs. 62.5%; PR = 1.52; 95% CI: 1.18–1.95). Myalgia-related and mixed TMD were the most frequent subtypes. Migraine patients with TMD had increased headache frequency and higher acute medication intake compared to those without TMD. However, no significant differences were found in…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 120 participants or records.
