Corticobasal Degeneration Overview

What is corticobasal degeneration?
Corticobasal degeneration (CBD) is a rare neurological disease in which parts of the brain deteriorate or degenerate. CBD is also known as corticobasal ganglionic degeneration, or CBGD.

Several regions of the brain degenerate in CBD. The cortex, or outer layer of the brain, is severely affected, especially the fronto-parietal regions, located near the center-top of the head. Other, deeper brain regions are also affected, including parts of the basal ganglia, hence the name "corticobasal" degeneration. The combined loss of brain tissue in all these areas causes the symptoms and findings seen in people with CBD.
