Suicide in 406 Mood-Disorder Patients With and Without Long-Term Medication: A 40 to 44 Years' Follow-Up

Abstract

There is no data on the variation in the suicide risk over lifetime and on the suicide-preventive effect of the long-term treatment of mood-disorder patients with antidepressants and neuroleptics. Our research focused on 186 unipolar (D), 60 bipolar II (Dm), 130 nuclear bipolar I (MD), and 30 preponderantly manic patients (M/Md); that were followed-up from 1963 to 2003. By 2003, 45 (11.1%) of the 406 patients had committed suicide. Suicide rates were highest among D patients (Standardized Mortality Ratio, SMR = 26.4), MD (SMR = 13.6), Dm (SMR = 10.6) and lowest among M/Md patients (SMR = 4.7). Prospectively, the suicide rate decreased over the 44 years' follow-up; Lithium, neuroleptics and antidepressants reduced suicides significantly. Long-term treatment also reduced overall mortality, and combined treatments proved more effective than mono-therapy.
