Maintenace Treatment of Bipolar
Disorder
MOOD STABILIZERS
– Lamotrigine
– Lithium
– Olanzapine
• Ameliorate affective and psychotic symptoms
during acute manic episodes
• Improve depression episodes during acute
bipolar depressive episodes
• Prevent future mood episodes with sustained
treatment at therapeutic levels (prophylactic
benefit)
Psychotherapy
• Patients taking lithium or other treatments for
bipolar I disorder are usually medicated for an
indefinite period of time to prevent episodes of
mania or depression
• Most psychotherapists insist that patients with
bipolar I disorder be medicated before starting
any insight-oriented therapy. Without such
premedication, most patients with bipolar I
disorder are unable to make the necessary
therapeutic alliance.
Psychotherapy
• When those patients are depressed, their abulia
seriously disrupts their flow of thoughts, and the
sessions are nonproductive.
• When they are manic, their flow of associations
can be rapid, and their speech can be so
pressured that the therapist may be flooded with
material and may be unable to make appropriate
interpretations or to assimilate the material into
the patient's disrupted cognitive framework.
Psychotherapy
• American Psychiatric Association (APA)
practice guideline for bipolar disorder
– Recommends combined therapy as the best
approach
– It increases compliance, decreases relapse, and
reduces the need for hospitalization
