A review of findings from the world’s largest study of Bipolar Disorder

The Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) ran from 1998 to 2005, with over 4,000 sufferers of Bipolar Disorder (BD) taking part in various trials and assessments over a two-year period.

Researchers were looking at how BD progresses through a person's life, how related it is to other psychiatric disorders, and how related it is to suicidality.

It found that few treatments alone were successful in treating BD, however psycho-social interventions (such as Cognitive Behaviour Therapy) and psycho-education interventions combined with mood stabilizers showed the most positive results.

BD was also shown to be strongly related to substance abuse and smoking, both of which affected the success or otherwise of chemical and psychological treatments.

Interestingly, paroxetine or bupropion were shown to be no more effective than a placebo in achieving sustained recovery (in this instance, determined as eight weeks of 'stable' behavior). So, too, were lamotrigine, risperidone, and inositol found to deliver minimal positive effects.

To the vexed, 'hidden', taboo subject of suicide -- the 'S' word not spoken of by the media (although thankfully that is slowly changing, at least in Australia). Suicidality persists with BD, even when treatment outcomes are good. The biggest predictor of suicidality being previous attempts.

The authors' conclusions
The authors of this review paper note seven contributions of the STEP-BD program:

1. Antidepressants remain poorly effective in treating BD;

2. BD is particularly disabling (tell me about it), and frequently doesn't respond to medications;

3. BD does respond modestly to intensive psycho-social interventions;

4. Other psychiatric disorders are common and destabilizing, yet anxiety disorders and smoking are able to be treated and when treated positively impact on BD;

5. An early age on onset of BD usually results in a more severe course of the illness, but rapid-cycling usually diminishes;

6. The sub-syndrome of Depression may be so strong as to mask the manic pole of BD, therefore careful symptom appraisal by psychiatrists is essential;

7. Suicidal thoughts persist in BD sufferers, and a previous attempt is a good indicator of a future event. However, by reducing feelings of 'hopelessness' in particular, there is the possibility of reducing the risk of suicide.
