Forensic analysis of psychiatric disorder-related deaths: A retrospective study in southern China

Background

Mental health issues have become increasingly severe globally over the last decade. The aim of the present study is to explore the characteristics of psychiatric disorder-related deaths in southern China and to provide a reference for forensic practice.

Methods

Upon examining forensic autopsy cases from the Faculty of Forensic Medicine at Zhongshan School of Medicine, Sun Yat-sen University, spanning from 2014 to 2023, we identified cases of death related to psychiatric disorders. We then analyzed pertinent data, including age, gender, forensic autopsy details, and medication records.Our findings indicated that out of 6013 forensic autopsies conducted, 63 deaths were associated with psychiatric disorders. Cardiovascular disease emerged as the primary cause of death. Notably, individuals who had died from psychiatric disorders exhibited heavier heart weights and smaller perivalvular diameters of the pulmonary artery, as well as coronary artery disease. Antipsychotic drug therapy was prevalent, with most patients being prescribed more than two medications.

Conclusion

Cardiovascular disease is the leading cause of death in psychiatric disorders, deaths related to psychiatric disorders are emerging as a challenge in forensic practice and require the concerted efforts of forensic scientists worldwide.
