Because the exact cause of CBD is unknown, there exists no formal treatment for the disease. Instead, treatments focus on minimizing the appearance or effect of the symptoms resulting from CBD. The most easily treatable symptom of CBD is parkinsonism, and the most common form of treatment for this symptom is the application of dopaminergic drugs. However, in general only moderate improvement is seen and the relief from the symptom is not long-lasting. In addition, palliative therapies, including the implementation of wheelchairs, speech therapy, and feeding techniques, are often used to alleviate many of the symptoms that show no improvement with drug administration.

Corticobasal degeneration (CBD) or corticobasal ganglionic degeneration (CBGD) is a rare, progressive neurodegenerative disease involving the cerebral cortex and the basal ganglia. CBD symptoms typically begin in people from 50–70 years of age, and the average disease duration is six years. It is characterized by marked disorders in movement and cognitive dysfunction, and is classified as one of the Parkinson plus syndromes. Clinical diagnosis is difficult, as symptoms of CBD are often similar to those of other disorders, such as Parkinson's disease (PD), progressive supranuclear palsy (PSP), and dementia with Lewy bodies (DLB). Due to the various clinical presentations associated with CBD, a final diagnosis can only be made upon neuropathologic examination.
