Progressive Supranuclear Palsy

Typical symptoms

As the disease progresses, a many people will start to build up an obscuring of vision and issues controlling eye development. Eye problems, specifically slowness of eye, movements, usually offer the first definitive clue that PSP is the proper diagnosis. People influenced by PSP particularly experience difficulty intentionally moving their gaze vertically. Furthermore can experience difficulty controlling their eyelids.

PSP is estimated to affect about 4-6.4/100,000 persons, or about 5-6 percent of persons thought to have Parkinsonism. The incidence rate for new cases for ages 50-99 is 5.3/100,000, the crude incidence rate is 1.1/100K (Bower et al, 1997; Schrag et al, 1999). The peak incidence is in the early sixties. Men are affected slightly more often than women. PSP does not generally run in families, although there are some pedigrees reported.
