Abstract
OBJECTIVE: To explore diagnostic and treatment issues concerning bipolar mixed states. METHOD: Bipolar mixed states are described and concerns about diagnostic and treatment difficulties are summarized and discussed. RESULT: Mixed states can present with equal admixtures of depressive or manic symptoms, or more commonly one component predominates. There is fair consensus, although little data, regarding the management of manic mixed states. However depressive mixed states are far more complex both in terms of recognition and management. People suffering from mixed states characteristically present with complaints of depression. CONCLUSIONS: The boundaries between depressive mixed states and agitated depression are vague, yet carry substantial therapeutic implications. Bipolar mixed states are often difficult to treat, and tend to take much longer to settle than either pure mania or depression. Furthermore there is data that treatment with antidepressants can worsen the course of mixed states. Hence missed diagnoses can potentially have negative clinical implications. Therefore in this paper the clinical presentation, diagnosis and therapy of mixed states is reviewed with a view to improving management.
