Concurrent Occurrence of Obsessive-Compulsive Disorder and Myofascial Pain Dysfunction Syndrome: A Case Series.

Objectives

Myofascial pain dysfunction syndrome (MPDS) is a musculoskeletal disorder with a multifactorial etiology. Some investigations suggest psychological disorders as a major risk factor for MPDS. This study is the first case series to report patients with obsessive-compulsive disorder (OCD) and MPDS comorbidity. Case presentation: Sixteen patients suffering from both MPDS and OCD with the chief complaint of pain or limitation in jaw opening were evaluated. The patients were between 18 to 55 years, the majority were females, the masseter muscle was the most commonly involved muscle (40%), and some of the patients had a history or sign of bruxism.

Conclusion

OCD symptoms should be considered in MPDS patients. Bruxism due to psychological disorders can be the cause of MPDS. The findings of this case series study should be verified in clinical studies to assess the relationship between MPDS, OCD, and parafunctional habits.
