Corticobasal Degeneration
What is Corticobasal Degeneration?
Corticobasal degeneration is a progressive neurological disorder
characterized by nerve cell loss and atrophy (shrinkage) of multiple areas of
the brain including the cerebral cortex and the basal ganglia. Corticobasal
degeneration progresses gradually. Initial symptoms, which typically begin at or
around age 60, may first appear on one side of the body (unilateral), but
eventually affect both sides as the disease progresses. Symptoms are similar to
those found in Parkinson disease, such as poor coordination, akinesia (an
absence of movements), rigidity (a resistance to imposed movement),
disequilibrium (impaired balance); and limb dystonia (abnormal muscle postures).
Other symptoms such as cognitive and visual-spatial impairments, apraxia (loss
of the ability to make familiar, purposeful movements), hesitant and halting
speech, myoclonus (muscular jerks), and dysphagia (difficulty swallowing) may
also occur. An individual with corticobasal degeneration eventually becomes
unable to walk.
Is there any treatment?
There is no treatment available to slow the course of corticobasal
degeneration, and the symptoms of the disease are generally resistant to
therapy. Drugs used to treat Parkinson disease-type symptoms do not produce any
significant or sustained improvement. Clonazepam may help the myoclonus.
Occupational, physical, and speech therapy can help in managing disability.
What is the prognosis?
Corticobasal degeneration usually progresses slowly over the course of 6 to 8
years. Death is generally caused by pneumonia or other complications of severe
debility such as sepsis or pulmonary embolism.
What research is being done?
The NINDS supports and conducts research studies on degenerative disorders
such as corticobasal degeneration. The goals of these studies are to increase
scientific understanding of these disorders and to find ways to prevent, treat,
and cure them.
