Abstract
Objective
To determine the efficacy of teaching patients with bipolar disorder (manic-depressive psychosis) to identify early symptoms of relapse and seek prompt treatment from health services.
Design
Single blind randomised controlled trial with matching on four baseline variables using a minimisation algorithm.
Setting
Mental health services in four NHS trusts (one teaching, three non-teaching).
Subjects
69 patients with bipolar disorder who had had a relapse in the previous 12 months.
Interventions
Seven to 12 individual treatment sessions from a research psychologist plus routine care or routine care alone.
Main outcome measures
Time to first manic or depressive relapse, number of manic or depressive relapses, and social functioning examined by standardised interviews every six months for 18 months.
Results
25th centile time to first manic relapse in experimental group was 65 weeks compared with 17 weeks in the control group. Event curves of time to first manic relapse significantly differed between experimental and control groups (log rank 7.04, df=1, P=0.008), with significant reductions in the number of manic relapses over 18 months (median difference 30% (95% confidence interval 8% to 52%), P=0.013). The experimental treatment had no effect on time to first relapse or number of relapses with depression, but it significantly improved overall social functioning (mean difference 2.0 (0.7 to 3.2), P=0.003) and employment (mean difference 0.7 (0.1 to 1.3), P=0.030) by 18 months.
Conclusion
Teaching patients to recognise early symptoms of manic relapse and seek early treatment is associated with important clinical improvements in time to first manic relapse, social functioning, and employment.
Key messages
  • Relapse rates in bipolar disorder are high despite modern drug treatment
  • Early prodromal symptoms are idiosyncratic to the patient and consistently develop in the weeks before manic or depressive relapse
  • This study found that teaching patients to recognise manic prodromes and seek early treatment significantly increased time to the next manic relapse and reduced the number of relapses
  • Teaching patients to recognise depressive prodromes and seek early antidepressant treatment did not significantly affect depressive relapses and increased the use of antidepressants
  • Teaching patients to recognise prodromes and seek early treatment improved social function and performance in employment
