What is (are) Olivopontocerebellar atrophy ?
Olivopontocerebellar atrophy (OPCA) is a progressive condition characterized by the degeneration of nerve cells (neurons) in specific areas of the brain. It occurs in several neurodegenerative diseases, including multiple system atrophy (MSA) and inherited and non-inherited forms of ataxia. OPCA may also occur in people with prion disorders and inherited metabolic diseases. The main symptom is clumsiness that slowly gets worse. Other symptoms may include problems with balance; speech or swallowing problems; difficulty walking; abnormal eye movements; muscle spasms; and neuropathy. Whether OPCA is inherited (and the inheritance pattern) depends on the underlying cause, if known. There is no cure for OPCA, and management aims to treat symptoms and prevent complications.
