[Maintenance therapy in bipolar affective disorder]

In bipolar affective disorder, the patients exhibit life-long susceptibility to periodic episodes of depression, mania, hypomania, including mixed phases. Maintenance therapy aims to prevent new episodes of affective disorder and associated self-destructive behavior, to prevent milder symptoms occurring between the actual episodes and to maintain functional capacity. Maintenance therapy is always initiated upon the diagnosis of bipolar affective disorder. In a type II disorder with mild symptoms, gradual termination of maintenance therapy can be considered while monitoring the status of the patient. The drug is chosen on the basis of individual benefit/risk ratio.
