Neuropathological Patterns of Homicidal Head Injuries: A One-Year Prospective Autopsy-Based Study in Nairobi, Kenya

Area of Science:

• Forensic Pathology
• Neuropathology
• Public Health

Background:

• Traumatic brain injury (TBI) is a major global cause of death and disability.
• Sub-Saharan Africa faces high TBI mortality, with homicide as a significant factor.
• Limited data exists on neuropathological patterns of homicidal head trauma in this region.

Purpose of the Study:

• To characterize injury mechanisms in homicidal head trauma cases.
• To describe demographic profiles of victims.
• To outline neuropathological findings in Nairobi, Kenya.

Main Methods:

• Prospective descriptive study at Nairobi City Mortuary over one year.
• Analysis of medicolegal autopsies for confirmed homicidal head injuries.
• Documentation of autopsy findings including skull fractures and intracranial injuries.

Main Results:

• Homicidal head injuries accounted for 59.4% of head injury deaths (630/1060).
• Young adult males (mean age 26.9 years, 96.1% male) were predominantly affected.
• Gunshot wounds (50.3%) and blunt force trauma (46.7%) were primary injury mechanisms.

Conclusions:

• Homicidal head injuries constitute a significant portion of violent deaths in Nairobi.
• Victims are typically young adult males, with specific neuropathological patterns observed.
• Findings highlight the need for targeted violence prevention strategies.
