Exploring Nontraumatic Brain Hemorrhage in Sudden and Unexpected Deaths: A Novel Autopsy-Based Investigation.

Background  There has been a surge in sudden and unexpected deaths, presenting a significant challenge for health policymakers and researchers. These individuals showed no signs of recent or past illnesses and died suddenly during routine activities like walking, standing, or working. Objective  This study focuses on exploring nontraumatic brain hemorrhage as a cause of death in autopsies of individuals without prior illnesses. The research aims to explore patterns, prevalence, and risk factors associated with nontraumatic brain hemorrhage, specifically obesity in sudden and unexpected deaths. Materials and Methods  This retrospective, observational study was conducted using autopsy cases with nontraumatic brain hemorrhage as the identified cause of sudden and unexpected deaths. Information on demographic details, medical history, and circumstances surrounding the deaths was collected. The cases were classified based on the body mass index according to the classification of the World Health Organization. Results  From April 2023 to January 2024, 10 cases of sudden and unexpected deaths due to nontraumatic brain hemorrhage were identified. Key findings included predominantly cases of obesity or overweight, deaths occurring predominantly between 8 p.m. and midnight, and all cases being males. Conclusion  The study sheds light on the surge in sudden deaths, specifically attributed to nontraumatic brain hemorrhage. The findings reveal a significant association between obesity and brain hemorrhage in sudden deaths, especially among males. The study's temporal analysis adds depth to understanding these patterns.
