Although Behçet disease and posttraumatic stress disorder both have a high prevalence of sleep problems, bruxism is extremely rare in these 2 disorders. Here, we report a rare case of concurrent Behçet disease and posttraumatic stress disorder, which presented with antidepressant-refractory sleep disturbance accompanied by teeth grinding, clenching, and snoring that was successfully treated with gabapentin. © 2014 by Lippincott Williams & Wilkins.
