Variant Creutzfeldt Jakob Disease
It is believed that vCJD is caused by proteins called prions. Prions are normal proteins in the body. These prions may fold up in a way that is not normal. This can change them into the protein that causes the illness. The build up of these prions may be linked to from vCJD.

After you are exposed, it can take up to 20 years until you feel sick. Symptoms can follow these three phases:
- Early phase (0 to 6 months)—mental health problems, such as depression, anxiety , withdrawal, memory problems, and difficulty pronouncing words
- Middle phase—neurological problems, such as problems with walking and coordination, muscle jerks and stiffness, and a hard time speaking
- Late phase—inability to talk or move
Your doctor will ask about your symptoms and health history. A physical exam will be done. You may have:
- Blood tests
- Electroencephalogram (EEG) to record the electrical activity of the brain
- Lumbar puncture —to test the fluid that protects the brain and spinal cord
- Brain biopsy
- Tonsillar biopsy
Pictures may be taken with:
- MRI scan
- CT scan
- SPECT scan
In many cases, a finding is not reached until an autopsy is done after death.
