Abstract

BACKGROUND: The weight of human brains is subject of numerous scientific research studies particularly in anatomy, pathology, and forensic medicine. Just a few investigations deal with a possible correlation between psychiatric disorders, especially suicidality, and brain weight. The results are contradictory. AIMS: This study aims to find out if postmortem brain weight is higher in suicide victims considering the discrepancies of previous studies.

METHOD: In a retrospective study, the weight of brains obtained by autopsies performed in the Institute of Legal Medicine in Frankfurt, Germany, was evaluated. Data of 99 suicide cases (64 males, 35 females) were compared with those obtained from similar number cases of sudden death in a matched pair analysis. In each case, body weight, height, and body mass index were also taken into account.

RESULTS: No significant differences in brain weight were found in suicide victims compared to those of the control group.

CONCLUSIONS: The brain weight depends on various parameters such as gender, age, body height, and weight. The selection criteria for suicide cases as well as for the corresponding control population are essential in evaluating the brain weight in suicide.
