Olivopontocerebellar atrophy (OPCA) is a degenerative disease that affects the cerebellum, pons, and inferior olives. Some synonyms for OPCA include Olivopontocerebellar degeneration, Olivopontocerebellar disorder (OPCD), and Multiple system atrophy-Cerebellar form (MSA-C). OPCA is a rare condition that affects the nervous system, leading to a gradual loss of balance, coordination, and muscle control. It is often characterized by symptoms such as tremors, stiffness, and slurred speech. While there is no known cure for OPCA, treatment can help manage its symptoms and improve the quality of life for those affected.
