OPCA; Olivopontocerebellar degeneration
Olivopontocerebellar atrophy is a disease that causes areas deep in the brain, just above the spinal cord, to shrink.
Olivopontocerebellar atrophy can be passed down through families (inherited form), or it may affect people without a known family history (sporadic form).
The cause of olivopontocerebellar atrophy in those without a history of the disease is not known. The disease slowly gets worse (is progressive).
This disease is slightly more common in men than in women.
