How is Creutzfeldt-Jakob disease (CJD) diagnosed?

ANSWER

There is no single test for Creutzfeldt-Jakob disease CJD. Doctors diagnose it from your symptoms. One sign of the disease is how fast it gets worse.

A few tests doctors can use include:

  • Magnetic resonance imaging (MRI). This brain scan puts together detailed images.
  • Electroencephalogram (EEG). This scan measures the brain’s electrical activity.
  • Lumbar puncture (spinal tap). Doctors draw fluid from the spinal column to test for certain proteins.
