Case studies of 25 patients who died by suicide in a NY hospital since 1912 are presented. Most patients presented were between 40-60 years old. Causes for suicide ranged from insomnia, hypochondria, guilt over a spouse’s death and a nervous breakdown. Severe hypochondria, insomnia, guilt, & aggressiveness were common trends in these cases. Half of the patients had previous suicide attempts. Men employed active means of suicide, while women used more passive means. (6 refs.)
