Sudden Death Due To Excited Delirium Syndrome: From Pathophysiology To Postmortem Assessment: Case Reports.

Area of Science:

• Forensic Pathology
• Toxicology
• Cardiology

Background:

• Excited Delirium Syndrome (ExDS) is a poorly understood condition associated with sudden death, frequently occurring during or after physical altercations, particularly with law enforcement.
• The exact pathophysiological mechanisms of ExDS remain unclear, though contributing factors like substance abuse and psychiatric conditions are suggested.
• ExDS-related deaths are likely underestimated, highlighting a need for better recognition and understanding.

Observation:

• Two forensic cases of ExDS involving males aged 42 and 34 are presented, both experiencing sudden death after scuffles with police.
• Case one involved documented drug use, while case two had a diagnosed psychiatric illness.
• Both cases exhibited potential trigger factors and were analyzed based on existing literature regarding ExDS.

Findings:

• Forensic analysis of ExDS necessitates comprehensive investigations to identify trigger factors and assess cardiac catecholaminergic hyperstimulation.
• The presented cases underscore the complexity of ExDS, involving a combination of physiological and psychological stressors.
• Post-mortem findings in ExDS require careful evaluation to distinguish from other causes of sudden death.

Implications:

• Improved understanding of ExDS pathophysiology can aid law enforcement and healthcare professionals in managing and preventing these critical incidents.
• Enhanced forensic methodologies can contribute to more accurate diagnoses and a better grasp of ExDS prevalence.
• This research supports the need for multidisciplinary approaches in the forensic investigation of sudden deaths potentially related to ExDS.
