Overview
Biopsy of the brain tissue is the definitive diagnostic test for Creutzfeldt-Jakob disease(CJD), but is not usually performed. EEG findings are not diagnostic of CJD, but may help in the diagnosis of CJD. Typical EEG findings in Creutzfeldt-Jakob disease include periodic biphasic or triphasic sharp wave complexes (PSWCs). Periodic synchronous discharges (PSDs) occur either before or in synchronicity with myoclonus.
Other Diagnostic Studies
Biopsy
- Deposits of prion protein (scrapie), PrPSc, can be found in the skeletal muscle and/or the spleen (approximately 30% of cases).
- Diagnosis of vCJD can be supported by biopsy of the tonsils, which harbor significant amounts of PrpSc.
- Biopsy of the brain tissue is the definitive diagnostic test, but is not usually performed.
