The Canadian Network for Mood and Anxiety Treatments (CANMAT) task force recommendations for the management of patients with mood disorders and comorbid personality disorders.

BACKGROUND: The association between mood disorders and personality disorders (PDs) is complicated clinically, conceptually, and neurobiologically. There is a need for recommendations to assist clinicians in treating these frequently encountered patients.

METHODS: The literature was reviewed with the purpose of identifying clinically relevant themes. MedLine searches were supplemented with manual review of the references in relevant papers. From the extant evidence, consensus-based recommendations for clinical practice were developed.

RESULTS: Key issues were identified with regards to the overlap of PDs and mood disorders, including whether certain personality features predispose to mood disorders, whether PDs can reliably be recognized if there is an Axis I disorder present, whether personality disturbances arise as a consequence or are a forme fruste of mood disorders, and whether personality traits or disorders modify treatment responsiveness and outcome of mood disorders.

CONCLUSION: This paper describes consensus-based clinical recommendations that arise from a consideration of how signals from the literature can impact clinical practice in the treatment of patients with comorbid mood and personality pathology. Additional treatment studies of patients with the comorbid conditions are required to further inform clinical practice.
