Summary

This study longitudinally tracked neuropsychological outcomes after severe electrical shock. Findings reveal persistent neurocognitive deficits and psychological symptoms, even after lower voltage injuries.

Area of Science:

  • Neuroscience
  • Psychology
  • Traumatology

Background:

  • Longitudinal studies on neuropsychological profiles following severe electrical shock are scarce, particularly for women.
  • Accidental electrical injuries can lead to significant neurocognitive and psychological sequelae.

Purpose of the Study:

  • To longitudinally examine the neuropsychological profiles of individuals after severe accidental electrical shocks.
  • To compare neurocognitive and psychological outcomes between a low-voltage and a high-voltage electrical injury case.

Main Methods:

  • Case report methodology involving two individuals with severe electrical injuries.
  • Longitudinal neuropsychological assessments conducted at multiple time points post-injury (2 months, 1 year, 2 years).
  • Assessment included evaluation of neurocognitive function, depression, and posttraumatic stress disorder.

Main Results:

  • A college-educated woman with a 120-V electrical shock showed diffuse, mild to moderate neurocognitive deficits and symptoms of depression and PTSD.
  • A man with a 69,000-V electrical injury exhibited minimal neurocognitive deficits but a similar psychological profile.
  • Contrasting neurocognitive findings but consistent psychological presentations were observed across both cases.

Conclusions:

  • Severe electrical shocks can result in long-term neurocognitive dysfunction and psychological distress.
  • Psychological sequelae, such as depression and PTSD, may be present regardless of the severity of neurocognitive impairment following electrical injury.
  • Further research is needed to understand the long-term impact of electrical injuries on brain function and mental health.
