What are the symptoms of vCJD?

Variant Creutzfeldt-Jakob disease (vCJD) causes the brain to become damaged over time. It is fatal. Symptoms include:

  • Tingling, burning, or prickling in the face, hands, feet, and legs. But there are much more common illnesses that cause these same symptoms. Having tingling in parts of your body does not mean you have vCJD.
  • Dementia.
  • Psychotic behavior.
  • Problems moving parts of the body. As the disease gets worse, a person is no longer able to walk.
  • Coma.

If a person does eat nerve tissue from an infected cow, he or she may not feel sick right away. The time it takes for symptoms to occur after you're exposed to the disease is not known for sure, but experts think it is years.

How is vCJD diagnosed?

There is no single test to diagnose vCJD. Doctors may think that a person has vCJD based on where the person has lived and the person's symptoms and past health. Imaging tests, such as an MRI, may be done to check for brain changes caused by vCJD.

Researchers are now trying to develop a blood test that looks for vCJD. But no blood test is available at this time.

A brain biopsy is the only way to confirm a diagnosis of vCJD.

How is vCJD treated?

There is no cure for vCJD. Treatment includes managing the symptoms that occur as the disease gets worse.
