Diagnosis

A diagnosis of corticobasal degeneration is made based on your signs and symptoms. However, your signs and symptoms could be due to another degenerative disease such as progressive supranuclear palsy, Alzheimer's disease, Pick's disease and Creutzfeldt-Jakob disease.

Researchers are looking at whether positron emission tomography (PET) and single-photon emission computerized tomography (SPECT) scans can uncover changes in the brain that are consistent with corticobasal degeneration. However, more research needs to be done in this area.
