Effect of psychosis on suicide risk in 1,593 patients with unipolar and bipolar affective disorders.
The authors report suicide risk among 1,593 patients with major depression or bipolar disorder, 443 (27.8%) of whom were psychotic (260 bipolar and 183 unipolar). The subjects were followed for 0-14 years, and their suicide experience was compared with that of the state population. Eight (19.5%) of the 41 suicide victims were from the psychotic group. The psychotic and nonpsychotic subjects in each diagnostic group had similar risks for suicide. A higher risk for suicide was not found in the bipolar subjects. The authors conclude that among patients with major affective disorder psychosis per se does not predispose to suicide.
