Creutzfeldt-Jakob Disease - Diagnosis

Creutzfeldt-Jakob disease is usually diagnosed by means of an electroencephalogram (EEG; pronounced ih-LEK-tro-in-SEH-fuh-luh-gram). An EEG is a procedure in which wires are attached to the brain. These wires detect electrical activity taking place in the brain. Certain distinctive patterns in the EEG are an indication of CJD.

CJD can be confirmed in an autopsy. An autopsy is a medical examination carried out on a dead body to determine what caused death. The autopsy can reveal the presence of abnormal proteins in the person's brain.
