Overview

Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of rare, degenerative, and usually fatal diseases that affect the nervous system of humans and animals. They are caused by the misfolding of a normal cellular protein, the prion protein (PrP), into an abnormal form (PrP^Sc).

Key Characteristics

  • Misfolded Proteins: Prion diseases are unique because they are caused by a misfolded protein rather than by a virus, bacterium, or other infectious agent.
  • Neurodegenerative: They lead to progressive neurodegeneration, resulting in symptoms such as dementia, ataxia, and involuntary movements.
  • Transmissibility: Some prion diseases can be transmitted through exposure to infected tissue.

Medical Practice and Safety

The management of complex medical conditions requires robust institutional cultures. Recent insights highlight the critical role of psychological safety in clinical environments.

  • AAMC emphasizes that psychological safety is essential for effective medical practice, enabling practitioners to report errors and discuss concerns without fear of retribution.
