Signs and symptoms of corticobasal degeneration include: Difficulty moving on one or both sides of the body, which gets worse over time. Abnormal postures of the hands or feet, such as a hand forming a clenched fist.
What is the condition where the brain shrinks and the nerve cells die?
Corticobasal degeneration is a rare disease in which areas of your brain shrink and your nerve cells degenerate and die over time. The disease affects the area of the brain that processes information and brain structures that control movement. This degeneration results in growing difficulty in movement on one or both sides of your body.

Sudden, brief involuntary muscle spasms that cause jerky movements (myoclonus) may also occur.
Why is corticobasal degeneration called corticobasal syndrome?

Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis.
Does corticobasal degeneration slow down?
There is no specific treatment that slows down the progression of corticobasal degeneration. Treatment is directed toward the specific symptoms that are apparent in each individual, although most cases prove resistant to such therapy.
What is corticobasal degeneration?
Corticobasal syndrome was first recognized in 1967 when Rebeiz, Kolodny, and Richardson Jr described three people with a progressive asymmetric akinetic-rigid syndrome combined with apraxia, which they named corticodentatonigral degeneration with neuronal achromasia. The condition was "mostly forgotten" until 1989, when Marsden et al. used the name corticobasal degeneration. In 1989 Gibb and colleagues provided detailed clinical and pathological descriptions in a further three cases adopting the name corticobasal degeneration, after which various other names included "corticonigral degeneration with nuclear achromasia" and "cortical basal ganglionic degeneration". Although the underlying cause of CBD is unknown, the disease occurs as a result of damage to the basal ganglia, specifically marked by neuronal degeneration or depigmentation (loss of melanin in a neuron) in the substantia nigra. Additional distinguishing neurological features of those diagnosed with CBD consist of asymmetric atrophy of the frontal and parietal cortical regions of the brain. Postmortem studies of patients diagnosed with CBD indicate that histological attributes often involve ballooning of neurons, gliosis, and tauopathy. Much of the pioneering advancements and research performed on CBD has been completed within the past decade or so, due to the relatively recent formal recognition of the disease.
What is the corticobasal syndrome?
Main article: Corticobasal syndrome. All of the disorders and dysfunctions associated with CBD can often be categorized into a class of symptoms that present with the disease of CBD.
How long does CBD last?
CBD symptoms typically begin in people from 50 to 70 years of age, and the average disease duration is six years. It is characterized by marked disorders in movement and cognition, and is classified as one of the Parkinson plus syndromes.
What are the symptoms of CBD?
Some of the most prevalent symptom types in people exhibiting CBD pertain to identifiable movement disorders and problems with cortical processing. These symptoms are initial indicators of the presence of the disease. Each of the associated movement complications typically appear asymmetrically and the symptoms are not observed uniformly throughout the body. For example, a person exhibiting an alien hand syndrome (explained later) in one hand, will not correspondingly display the same symptom in the other hand. Predominant movement disorders and cortical dysfunctions associated with CBD include:
What is alien hand syndrome?
This disorder involves the failure of an individual to control the movements of their hand, which results from the sensation that the limb is "foreign".
Is FTDP-17 a corticobasal disease?
Alzheimer's disease, Pick's disease, FTDP-17 and progressive supranuclear palsy can display a corticobasal syndrome. It has been suggested that the nomenclature of corticobasal degeneration only be used for naming the disease after it has received verification through postmortem analysis of the neuropathology.
Is CBD a neuropathology?
Diagnosis is difficult, as symptoms are often similar to those of other disorders, such as Parkinson's disease, progressive supranuclear palsy, and dementia with Lewy bodies, and a definitive diagnosis of CBD can only be made upon neuropathologic examination.

Terminology
- The symptoms of corticobasal degeneration develop due to the progressive deterioration of tissue in different areas of the brain. Nerve cell loss occurs in specific areas, leading to atrophy or shrinkage in specific lobes of the brain. The severity and type of symptoms depend on the area of the brain affected by the disease. The cerebral cortex and basal ganglia are the two areas of the …
