Histories of substance abuse, panic and suicidal ideation in schizophrenic patients with histories of post-psychotic depressions

Abstract

1. Forty patients who had had syndromally-defined episodes of postpsychotic depression at least 6 months previously were interviewed in detail for life-time histories of substance abuse, panic attacks and suicidal ideation. 2. No relationship was found between life-time history of suicidal ideation and substance abuse. 3. Statistically significant associations were found between lifetime history of suicidal ideation and both a life-time history of panic attacks and the panic disorder syndrome.
