Abstract: One of the strongest predictors of suicide is a suicide attempt in the history of the patient. The question, however, is to what extent age and duration of the illness affects the risk of a suicide attempt. In this study, we examined the course of 310 patients with primary affective disorders before lithium prophylaxis and compared the clinical data of those with and without suicide attempts in their history. In a subgroup of 98 patients with suicide attempts, measures for both suicide attempts and inpatient episodes were investigated. Comparing patients with suicide attempts and those without, we found no difference between duration of illness and number of previous episodes between the two groups. However, those with a suicide attempt in their history had an earlier onset of the illness. In the group of 98 suicide attempters, we found no significant correlation between age and rates for both episodes and suicide attempts, which indicates that these rates were not declining as the illness progressed and the patient aged. Dividing the sample into three different age groups, episode rates and rates of attempted suicide were found to be positively correlated in all age groups, again indicating that as long as episodes occur, the suicide risk does not decline. The results are not in favor of findings which suggest that the risk of attempting suicide might manifest itself primarily in the early course of the illness or that suicide attempts in the early course of illness provide a 'cathartic effect' which leads to a lower risk in the later course of the illness. Rather, the findings support the view that the risk of suicide attempts in recurrent affective disorders is unchanged in all age groups and throughout all stages of untreated illness.
