Clinical Classification Guidelines
Medical Intelligence & Overview
Kuru is a rare, progressive neurological disorder that was historically found among the Fore people of Papua New Guinea. It belongs to a group of diseases called transmissible spongiform encephalopathies (TSEs), which are caused by abnormal prion proteins. Kuru is characterized by tremors, loss of coordination, and eventual death. Although it is now almost eradicated, studying kuru has provided valuable insights into prion diseases and their transmission mechanisms.
Causes & Symptoms
Clinical Causes: Transmission through cultural practices involving endocannibalism, especially the ritual consumption of brain tissue of deceased relatives Ingestion of infected neural tissue containing abnormal prions, leading to the accumulation of prions in the body No evidence suggests spontaneous development; infection is primarily acquired through specific human behaviors Genetic predispositions are not known to play a significant role in kuru
Key Symptoms: Progressive tremors and difficulty with coordinated movements Muscle weakness and stiffness Difficulty walking and maintaining balance Changes in speech, such as slurred speech Difficulty swallowing (dysphagia) Mood changes, confusion, and behavioral disturbances In advanced stages, severe neurological decline leading to coma
Diagnostic & Treatment

Treatment Protocols: There is currently no cure or effective treatment for kuru. Management primarily focuses on supportive care aimed at alleviating symptoms and improving quality of life. This includes:
