Definition of Olivopontocerebellar atrophy
Olivopontocerebellar atrophy is a disease that causes areas deep in the brain, just above the spinal cord, to shrink.
Causes, incidence, and risk factors
Olivopontocerebellar atrophy can be passed down through families (inherited form), or it may affect people without a known family history (sporadic form).
Symptoms tend to start sooner at a younger age in people with the inherited form. The main symptom is clumsiness () that slowly gets worse. There may also be problems with balance, slurring of speech, and difficulty walking.
Signs and tests
A thorough medical and neurological examination, as well as a symptom and family history, are needed to make the diagnosis.
There is no specific treatment or cure for this disease. Therapy is aimed at treating symptoms and preventing complications. This may include:
The disease slowly gets worse, and there is no cure. The outlook is generally poor. However, it may be years before someone becomes significantly disabled.
