@JessicaLynn - I think it's completely possible scientists could find a cure for this and other forms of prion disease while doing other research. I know a lot of research is being done right now about gene therapy, which could potentially treat or cure a lot of different diseases.
Gerstmann-Straussler-Scheinker disease sounds pretty similar to Alzheimer's disease too. The clumsiness, muscles spasms, and eventual dementia are also Alzheimer's symptoms. It must be hard for doctors to differentiate. I wonder if some people are treated for Alzheimer's when they really have Gerstmann-Straussler-Scheinker disease instead?
