Your Question

Is corticobasal degeneration hereditary? If so, is there anything that can be done to slow it down?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What is corticobasal degeneration?

Corticobasal degeneration is characterized by the break down (degeneration) of parts of the brain, including the cerebral cortex and basal ganglia. The cerebral cortex is responsible for most of the brain's processing of information, and the basal ganglia are deep brain structures that help start and control movement. Signs and symptoms of corticobasal degeneration include poor coordination, loss of movement, rigidity, poor balance, unnatural posturing of the muscles, intellectual (cognitive) impairment, speech impairment, muscular jerks, and difficulty swallowing. These symptoms develop and worsen over time. Currently the cause of corticobasal degeneration is not known.[1]

Is corticobasal degeneration inherited?

Currently the cause of corticobasal degeneration is not known.[1][2] Researchers believe that a number of different factors may be involved in the development of this condition, including age as well as genetic and environmental influences. A protein called tau may play a role in the development of this condition. Tau is a specific type of protein that is normally found in the brain. Its function is complex and not fully understood. In corticobasal degeneration, abnormal levels of tau accumulate in the brain cells, eventually leading to their deterioration. Exactly why this happens in unknown. Tau also appears to play a role in other neurodegenerative diseases like Alzheimer disease, Pick's disease, progressive supranuclear palsy, and frontotemporal dementia.[2]

Is there anything that can be done to slow the progression of corticobasal degeneration?

No. Currently there is not a treatment available to slow the course of corticobasal degeneration. Treatment of corticobasal degeneration is supportive.[1] 

The following resource can be used to search for clinical trials enrolling people with corticobasal degeneration. Some of the trials may involve the investigation of new therapies.

The U.S. National Institutes of Health, through the National Library of Medicine, developed ClinicalTrials.gov to provide patients, family members, and members of the public with current information on clinical research studies. You can access a listing of on-going and completed studies related to corticobasal degeneration through the following link. After you click on the study, review its "eligibility" criteria to determine its appropriateness. Use the study’s contact information to learn more. Check this site often for regular updates.

You can also contact the Patient Recruitment and Public Liaison (PRPL) Office at the National Institutes of Health (NIH) to speak with a specialist, who can help you determine if you are eligible for any clinical trials.
