G & J, p 729

Page 61: Bipolar disorder

Benzodiazepines

Page 63: Bipolar disorder

Antidepressants

• Q. What should be the approach to a pt on antidepressants and treating that pt’s first-break manic episode?

Page 64: Bipolar disorder

Antidepressants

Page 66: Bipolar disorder

breakthrough

• Ans.• 1. Check serum levels to see if the pt is in

therapeutic levels and consider higher levels that are still with acceptable levels, e.g. valproate at 90, consider pushing to 120..

• 2. Consider adding an antipsychotic• 3. Consider short-term use of a benzodiazepine,

especially if very agitated.

Page 67: Bipolar disorder

Inadequate Response

• Q. If first choice med fails to develop an adequate in a manic or mixed pt in two weeks, what to do? [Ans. has five general categories.]

Page 68: Bipolar disorder

Inadequate response

• Ans. Consider:– Another first line med– Adding an antipsychotic if not already using.

If using, consider switching to another antipsychotic.

– Adding carbamazepine/oxcarbazepine– Clozapine [Practice Guideline wording not

clear, but apparently as an addition]– ECT

Page 69: Bipolar disorder

ECT

Page 72: Bipolar disorder

Acute depression

• Ans. Three: Li, lamotrigine or olanzapine-fluoxetine combination.

[Ref: Watch]

Page 73: Bipolar disorder

SSRIs

• Q. What about SSRIs for depressive episode?

Page 74: Bipolar disorder

SSRIs

• Ans. Not recommended as monotherapy. May be useful as an adjunct to a mood stabilizer, but mood stabilizers are first choice.

• [Tertiary centers for bipolar disorders find they have to use an antidepressant with about a fifth of their pts.]

Page 75: Bipolar disorder

Acute depression

• Q. What about ECT?

Page 76: Bipolar disorder

Acute depression

• Ans. ECT is useful for:

• 1] life-threatening inanition

• 2] suicidal

• 3] psychotic

• 4] pregnant

Page 77: Bipolar disorder

Acute depression

• Q. What about psychotherapy?

Page 78: Bipolar disorder

• In addition to meds – not as solo, interpersonal or CBT has empirical basis.

• Psychodynamic is frequently used but lacks controlled studies.

Page 79: Bipolar disorder

Breakthrough depression

• Q. Bipolar pt on maintenance meds and has breakthrough depression. What to do?

Page 80: Bipolar disorder

Breakthrough depression

• Ans. First, ensure serum levels of meds are at high therapeutic range.

Page 81: Bipolar disorder

Breakthrough depression

• Q. If serum levels of the mood stabilizers are at a high therapeutic level and still depressed? [“Breakthrough depression” = bipolar pt who was on maintenance mood stabilizer as adequate levels. List three general choices.]

Page 82: Bipolar disorder

breakthrough depression

• Ans. Three general choices.

• 1] Add antidepressant: SSRI/venlafaxine/bupropion or MAOI or

• 2] If psychotic, add antipsychotic [probably an acceptable choice even if not psychotic], or

• 3] ECT

Page 83: Bipolar disorder

Still depressed

• Q. When to consider ECT?

Page 84: Bipolar disorder

Still depressed, ECT

• Ans. ECT when:

• -- medication resistant

• -- psychotic signs

• -- catatonic features

Page 85: Bipolar disorder

Rapid cycling

• Q. What is definition of rapid cycling?

Page 86: Bipolar disorder

Rapid cycling

• Ans. 4 or more episodes/year and there has been two months of remission or partial between episodes. Hypomanic episodes count. Rapid cycling also can mean switching from one polarity to the opposite without the two months of remission or partial remission.

Page 87: Bipolar disorder

Rapid cycling

• Q. Identify two conditions that can lead to rapid cycling.

Page 88: Bipolar disorder

Rapid cycling

• Ans. There are lots, and the Practice Guideline lists two that may be among the examination’s choices

• -- substances, including alcohol

• -- hypothyroidism

Page 89: Bipolar disorder

Rapid cycling

• Q. Meds for rapid cycling?

Page 90: Bipolar disorder

Rapid cycling - meds

Meds for rapid cycling:

• Li

Page 91: Bipolar disorder

Rapid cycling

• Q. Rapid cycling pt doesn’t respond to your initial med selection, so what next?

Page 92: Bipolar disorder

Rapid cycling

• Ans. Two choices?

• -- Add another mood stabilizer

• Or

• -- Add an antipsychotic

• [While not mentioned by Guideline, ECT is also an acceptable answer]

Page 93: Bipolar disorder

Catatonic signs

• Q. Which phase has catatonic signs and of what signs do they commonly consist?

Page 94: Bipolar disorder

Catatonic signs

• Ans. More common in manic episodes and consist of motor excitement, mutism, and stereotypic movements.

Page 95: Bipolar disorder

Catatonic

• Q. Treatment choice for bipolar with catatonia?

Page 96: Bipolar disorder

Catatonia

• Ans. While ECT is most efficacious, Practice Guideline seems to imply trying a benzodiazepine first.

Page 97: Bipolar disorder

Maintenance

• Q. Preferred meds for the maintenance [stable] phase?

Page 98: Bipolar disorder

Maintenance

• Ans.

• Treatments with the most empirical support are Li and valproate.

Watch provides additional support for lamotrigine and olanzapine.

Page 99: Bipolar disorder

Maintenance - ECT

• Q. ECT?

Page 100: Bipolar disorder

Maintenance - ECT

• Ans. Maintenance ECT should be consider for those pts whose stabilization was achieved with ECT. [In discussing this, keep in mind that outpt ECT, like meds, has high non-compliance.]

Page 101: Bipolar disorder

Maintenance - Antipsychotics

• Q. Role of antipsychotics for maintenance?

Page 102: Bipolar disorder

Maintenance - antipsychotics

• Ans. Not easy to answer. Practice Guidelines says they should be discontinued unless they have been shown with a pt to be needed to prevent relapse or to prevent psychotic features.

• APA Watch on bipolar suggests that olanzapine is OK for maintenance, and is clear in saying that typical antipsychotics are not desirable. Other atypicals are listed for maintenance [e.g., Stephen Stahl’s Prescription Guide].

Page 103: Bipolar disorder

Maintenance - psychotherapies

• Q. Role of psychotherapies. If a role, which are used?

Page 104: Bipolar disorder

Page 106: Bipolar disorder

Maintenance – group therapy

• Ans. Supportive groups are used to educate as to:– Information about the illness– Adherence strategies– Address enhancing self-esteem– Adaptation to having a chronic illness– Management of psychosocial issues, e.g. job

related issues

Page 107: Bipolar disorder

Maintenance – family therapy

• Q. Family therapy in the maintenance phase is used to?

Page 108: Bipolar disorder

Maintenance – family therapy

• A. Same as the issues listed for group psychotherapy supra.

Page 109: Bipolar disorder

Maintenance - problems

• A. If the pt is still having subthreshold symptoms or breakthrough manic or depression, what to do?

Page 110: Bipolar disorder

Maintenance - problems

• A. Consider:

• -- adding another mood stabilizer

• -- adding an atypical antipsychotic

• -- adding an antidepressant if the mood breakthrough is depressive signs.
