Area of Science:

  • Neuroscience
  • Infectious Diseases
  • Veterinary Medicine

Background:

  • Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder within the transmissible spongiform encephalopathies (TSEs) group.
  • Prions, the controversial causative agents of TSEs, are implicated in both human and animal diseases.
  • Bovine spongiform encephalopathy (BSE) outbreaks in the 1980s and the emergence of variant CJD (nvCJD) in the 1990s highlighted public health concerns.

Purpose of the Study:

  • To provide a comprehensive overview of Creutzfeldt-Jakob disease.
  • To detail the history, etiology, and transmission routes of CJD.
  • To outline clinical features, diagnostic approaches, treatment strategies, and decontamination procedures.

Main Methods:

  • Literature review of historical and current research on CJD and related prion diseases.
  • Analysis of epidemiological data concerning BSE and nvCJD.
  • Synthesis of information on clinical presentation, diagnosis, and management.

Main Results:

  • CJD is a fatal prion disease with diverse clinical manifestations.
  • Transmission can occur through various routes, including iatrogenic and dietary exposure (nvCJD linked to contaminated beef).
  • Effective decontamination protocols are crucial for preventing iatrogenic spread.

Conclusions:

  • CJD represents a significant challenge in neurodegenerative and infectious disease research.
  • Understanding prion biology and transmission is key to preventing future outbreaks.
  • Strict adherence to sterilization and decontamination guidelines is essential for healthcare settings.
