Fibromyalgia (FM) is a complex musculoskeletal pain disorder characterized by widespread pain, fatigue, and other functional symptoms. Patients with FM are frequently affected by psychiatric disorders. Clinicians typically observe certain personality characteristics or traits associated with FM, but there is still a lack of studies about personality disorders (PDs) in patients with FM. Aim of our brief review is to summarize the literature to date on prevalence of PDs in FM. We searched the PubMed electronic database for all articles up to 1 February 2017, and identified a number of reports about prevalence of PDs in patients with FM. Most of studies show that the proportion of PDs diagnosed in patients with FM appears far greater than that found in the general population. We suggest that is very useful to evaluate PDs in patients with FM systematically, in order to improve the understanding, assessment, and treatment of this clinical condition.
