Response, remission, and recovery in bipolar disorders: what are the realistic treatment goals?

Abstract

Bipolar disorder presents particular challenges with regard to assessing response to therapy. Criteria for determining remission and recovery have been suggested for mood disorders, but the clinical usefulness of these terms in bipolar disorder is elusive. Formal psychological rating scales may be impractical in a routine medical practice setting. As an alternative, clinicians might probe for information about particular "signal events," such as sleep disturbances, that may herald mood fluctuations. The ultimate goal of bipolar management should be complete and sustained remission, whenever possible, although most patients will not achieve this status for any significant length of time. Furthermore, overaggressive management might entail pushing medication doses to intolerable levels. Individual treatment goals should always take into account patient acceptance of side effect burden, allowing for trade-offs between treatment effect and quality of life. Noncompliance with therapy, notoriously common among patients suffering from bipolar disorder, can stem from drug side effects, treatment ineffectiveness, or even treatment success if the patient misses the manic symptoms. Despite effective treatment, relapse is common. Realistic treatment goals should strive for sustained symptom abatement while maximizing patient quality of life from visit to visit.
