Treatment

Although there is no cure for progressive supranuclear palsy, treatments are available to help ease symptoms of the disorder. The options include:

• Parkinson's disease medications, which increase levels of a brain chemical involved in smooth, controlled muscle movements. The effectiveness of these medications is limited and usually temporary, lasting about two to three years.
• OnabotulinumtoxinA (Botox), which may be injected in small doses into the muscles around your eyes. Botox blocks the chemical signals that cause muscles to contract, which can improve eyelid spasms.
• Eyeglasses with bifocal or prism lenses, which may help ease problems with looking downward. Prism lenses allow people with progressive supranuclear palsy to see downward without moving their eyes down.
• Speech and swallowing evaluations, to help you learn safer swallowing techniques.
• Physical therapy and occupational therapy, to improve balance.

Researchers are working to develop medication to treat progressive supranuclear palsy, including therapies that may block the formation of tau.
