What is paraneoplastic cerebellar degeneration?

Paraneoplastic cerebellar degeneration is an inflammatory autoimmune process that occurs due to the destruction of cerebellar Purkinje cells by onconeural antibodies; these antibodies are produced by the immune system in response to a protein that is expressed by tumor cells.

How long can you live with cerebellar degeneration?

Life expectancy is generally shorter than normal for people with hereditary ataxia, although some people can live well into their 50s, 60s or beyond. In more severe cases, the condition can be fatal in childhood or early adulthood.

What causes degeneration of the cerebellum?

Cerebellar degeneration can be caused by a variety of factors including inherited gene changes ( mutations ), chronic alcohol abuse, and paraneoplastic disorders. Treatment for cerebellar degeneration varies depending on the underlying cause.

Is paraneoplastic cerebellar degeneration hereditary?

The hallmark of paraneoplastic cerebellar degeneration (PCD) is the presence of an immune response reactive with intracellular proteins of Purkinje or other neurons or, less commonly, against neuronal surface antigens. There is no commonly associated genetic pathway with PCD.

Is cerebellar degeneration fatal?

Prognosis. The long-term prospect for patients suffering from cerebellar degeneration differs according to the underlying cause of the disease. Each inherited or acquired disease that results in cerebellar degeneration has its own specific prognosis, however most are generally poor, progressive and often fatal.

Can cerebellar atrophy be reversed?

Summary: No cures are possible for most patients who suffer debilitating movement disorders called cerebellar ataxias. But in a few of these disorders, patients can be effectively treated with regimens such as prescription drugs, high doses of vitamin E and gluten-free diets.

Can cerebellar degeneration be reversed?

There is no cure for hereditary forms of cerebellar degeneration. Treatment is usually supportive and is based on the person’s symptoms. For example, drugs may be prescribed to ease gait abnormalities. Physical therapy can strengthen muscles.

Is cerebellar degeneration progressive?

Each inherited or acquired disease that results in cerebellar degeneration has its own specific prognosis, however most are generally poor, progressive and often fatal.

What is paraneoplastic cerebellar degeneration (PCD)?

Summary Summary. Paraneoplastic syndromes are a group of rare disorders that include paraneoplastic cerebellar degeneration (PCD). Paraneoplastic syndromes are thought to result from an abnormal immune response to an underlying (and often undetected) malignant tumor. PCD is a rare, non-metastatic complication of cancer.

What are paraneoplastic syndromes?

Paraneoplastic syndromes are thought to result from an abnormal immune response to an underlying (and often undetected) malignant tumor. PCD is a rare, non-metastatic complication of cancer.

Which antibodies are involved in the pathophysiology of cerebellar degeneration?

Multiple onconeural antibodies were detected in patients with paraneoplastic cerebellar degeneration and are thought to the culprit in the cerebellar Purkinje cells injury. These antibodies include anti-Yo (PCA-1), anti-Hu, anti-Ri, anti-Tr, anti-VGCC, anti-Ma, anti-CRMP5 (anti-CV2), and anti-mGluR.[14]
