Living with Kuru

A rare brain disease from a prion, found in one region of New Guinea and linked to a ritual practice that has stopped.

Understanding Kuru

Kuru is a prion disease that affects the brain and was found only in the highlands of New Guinea.

It was mainly seen in adult females and children of both sexes. It begins with tremor and balance trouble, followed by muscle weakness and loss of bladder control. It is linked to ritual cannibalism and has become rare since the practice was stopped. In the brain, nerve cells are lost, mostly in the cerebellum.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes these features:

  • Tremor
  • Balance and coordination problems (ataxia)
  • Muscle weakness
  • Loss of bladder control

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
