Fatal self-harm (FSH) victims had significantly higher brain weights than natural death cases. However, brain weight did not differ significantly between various FSH methods in elderly individuals.

Area of Science:

  • Neuropathology
  • Forensic Science
  • Gerontology

Background:

  • Limited research exists on how suicide methods influence post-mortem brain weight.
  • Understanding these factors is crucial for forensic and neuropathological studies.

Purpose of the Study:

  • To investigate post-mortem brain weight variations in elderly individuals across different fatal self-harm (FSH) methods and compare them to natural deaths.
  • To contribute to the limited literature on suicide methods and brain weight.

Main Methods:

  • A retrospective review of coroners' records for individuals aged 60 and above.
  • Classified suicide, misadventure, and open verdicts as FSH.
  • Compared post-mortem brain weights of 142 FSH victims with 150 natural death victims.

Main Results:

  • Victims of FSH exhibited significantly higher brain weights than those who died from natural causes (P < 0.01).
  • Brain weights in both groups remained within the normal range for the elderly population.
  • No statistically significant differences in brain weight were observed among various FSH methods (P > 0.05).

Conclusions:

  • Findings suggest a potential link between fatal self-harm and higher brain weight, warranting further critical examination.
  • Further research should include younger age groups and explore neurochemical aspects.
  • Establishing a national neuropathological database for FSH victims could facilitate future research.
