Blunt force head and chest injuries from motor vehicle collision

AI-generated summary

A 77-year-old male with a history of seizures (2017, 2023) died from blunt force head and chest injuries sustained in a motor vehicle collision on 10 March 2024. The vehicle travelled at 157 km/h approaching a red traffic light, with braking applied 2-3 seconds before impact at 108 km/h. Toxicological analysis revealed therapeutic levels of lamotrigine and citalopram, with non-toxic mirtazapine. Critical finding: citalopram can reduce seizure threshold and reduce lamotrigine efficacy; mirtazapine causes drowsiness impairing coordination. An acute medical episode such as seizure cannot be excluded as the cause of the collision. The patient's driving license had been suspended for seizures in 2023 and reinstated in June 2023. Medical management involved potential drug-drug interactions that may have increased seizure risk in a patient with documented epilepsy and recent seizure activity.

Contributing factors

  • History of seizures (2017, 2023)
  • Possible acute medical episode (seizure) immediately preceding collision
  • Drug-drug interaction: citalopram and lamotrigine reducing seizure threshold
  • Mirtazapine causing drowsiness and sedation impairing coordination
  • Excessive speed (157 km/h in 100 km/h zone, 140 km/h in 80 km/h zone)
  • Vehicle veering and lane instability in seconds before impact
  • Mild 3-vessel coronary artery disease with high plaque burden
  • Multiple comorbidities including COPD, diabetes, depression
