depression lessens. If the patient is not seriously depressed, it is often quite appropriate to initiate intensive psychotherapeutic efforts, since flux periods are a good time to effect change. A catharsis of repressed anger and guilt may be beneficial. Therapy during or just after the acute stage may focus on coping techniques, with some practice of alternative choices. Depression-specific psychotherapies help improve self-esteem, increase assertiveness, and lessen dependency. Interpersonal psychotherapy for depression has shown efficacy in the treatment of acute depression, helping patients master interpersonal stresses and develop new coping strategies. Cognitive behavioral therapy for depression addresses patients’ patterns of negative thoughts, called cognitive distortions, that lead to feelings of depression and anxiety. Treatment usually includes homework assignments such as keeping a journal of cognitive distortions and of positive responses to them. The combination of drug therapy plus interpersonal psychotherapy or cognitive behavioral therapy is more effective than either modality alone. It is usually helpful to involve the spouse or other significant family members early in treatment. Mindfulness-based cognitive therapy has reduced relapse rates in several randomized controlled trials. In two studies, it was as effective as maintenance medication in preventing relapse. This therapy incorporates meditation and teaches patients to distance themselves from depressive thinking. It may be a preferable alternative for individuals who wish to have an alternative to long-term medications to stay free of depressive episodes.
C. Social Flexible use of appropriate social services can be of major importance in the treatment of depression. Since alcohol is often associated with depression, early involvement in alcohol treatment programs such as Alcoholics Anonymous can be important to future success (see Alcohol Dependency and Abuse, below). The structuring of daily activities during severe depression is often quite difficult for the patient, and loneliness is often a major factor. The help of family, employer, or friends is often necessary to mobilize the patient who experiences no joy in daily activities and tends to remain uninvolved and to deteriorate. Insistence on sharing activities will help involve the patient in simple but important daily functions. In some severe cases, the use of day treatment centers or support groups of a specific type (eg, mastectomy groups) is indicated. It is not unusual for a patient to have multiple legal, financial, and vocational problems requiring legal and vocational assistance.
D. Behavioral When depression is a function of self-defeating coping techniques such as passivity, the role-playing approach can be useful. Behavioral techniques, including desensitization, may be used in problems such as phobias where depression is a by-product. When depression is a regularly used interpersonal style, behavioral counseling to family members or others can help in extinguishing the behavior in the patient. Behavioral activation, a technique of motivating depressed patients to begin engaging in pleasurable activities, has been shown to be a useful depression-specific psychotherapy.
``Treatment of Mania Acute manic or hypomanic symptoms will respond to lithium or valproic acid after several days of treatment, but it is increasingly common to use atypical neuroleptics as adjunctive treatment or monotherapy. High-potency benzodiazepines (eg, clonazepam) may also be useful adjuncts in managing acute cases. Some schizoaffective disorders and some cases of so-called schizophrenia are probably atypical bipolar affective disorder, for which lithium treatment may be effective.
A. Neuroleptics Acute manic symptoms of agitation and psychosis may be treated initially with the atypical antipsychotic olanzapine, (eg, 5–20 mg orally), risperidone (2–3 mg orally), or aripiprazole (15–30 mg) in conjunction with a benzodiazepine if indicated. Alternatively, when behavioral control is immediately necessary, olanzapine in an injectable form (2.5–10 mg intramuscularly) or haloperidol, 5–10 mg orally or intramuscularly repeated as needed until symptoms subside, may be used. The dosage of the neuroleptic may be gradually reduced after lithium or another mood stabilizer is started (see below). Olanzapine is approved as a maintenance treatment for bipolar disorder.
B. Clonazepam Clonazepam can be an alternative or adjunct to a neuroleptic in controlling acute behavioral symptoms. Clonazepam has the advantage of causing no extrapyramidal side effects. Although 1–2 mg orally every 4–6 hours may be effective, up to 16 mg/d may be necessary.
C. Lithium As a prophylactic drug for bipolar affective disorder, lithium significantly decreases the frequency and severity of both manic and depressive attacks in about 70% of patients. A positive response is more predictable if the patient has a low frequency of episodes (no more than two per year with intervals free of psychopathology). A positive response occurs more frequently in individuals who have blood relatives with a diagnosis of manic or hypomanic attacks. Patients who swing rapidly back and forth between manic and depressive attacks (at least four cycles per year) usually respond poorly to lithium prophylaxis initially, but some improve with continued long-term treatment. Carbamazepine (see below) has been used with success in this group. In addition to its use in manic states, lithium is sometimes useful in the prophylaxis of recurrent unipolar depressions (perhaps undiagnosed bipolar disorder). Lithium may ameliorate nonspecific aggressive behaviors and dyscontrol syndromes. The dosages are the same as used in bipolar disorder. Most patients with bipolar disease can be managed long-term with lithium alone, although some will require continued or intermittent use of a neuroleptic, antidepressant, or carbamazepine.
