Diagnosis of Corticobasal Degeneration
How is CBD diagnosed?
Early in the disease course, it is often difficult to distinguish CBD from similar neurodegenerative diseases. Diagnosis of CBD involves a careful neurological exam, combined with one or more types of laboratory evaluations. Electrophysiological studies, including an EEG (electroencephalogram), may show changes in brain function over time that are consistent with the neurodegeneration. CT or MRI scans can also be used in this way, providing images of asymmetric atrophy of the fronto-parietal regions of the brain's cortex, the regions most frequently involved in the disease.
