The OPCAs are progressive neurodegenerative disorders that have no definitive treatment. Eventually, many patients become wheelchair bound. Severe dysarthria, anarthria, and dysphagia are not uncommon as the disease progresses.

  • Morbidity increases significantly, including falls and aspiration pneumonia.

  • Enteral feeding becomes necessary for many patients.

  • Death commonly results from aspiration pneumonia.

  • The duration of familial OPCA is approximately 15 years. The duration of sporadic OPCA is approximately 6 years.
