The purpose of this study is to determine if there is an anatomical co
rrelate, namely adrenal hypertrophy, among people who have commited su
icide. The adrenal weights and other relevant information were collect
ed prospectively from 118 consecutive coroner's cases of sudden death
in the province of Ontario. No statistically significant difference wa
s found between the adrenal weights of those who had committed suicide
, whether violent or non violent, and those dying suddenly of causes n
ot self-inflicted. This was true irrespective of the age of the subjec
ts, their sex or the centre at which the autopsy was performed. This f
inding does not support the findings of an earlier report of increased
adrenal weight in successful suicides. The incidental finding of incr
eased adrenal weight in all subjects is of some significance.
