How do you exactly prevent progressive supranuclear palsy?

You cannot. Psp is progressive supranuclear palsy in the group of parkinsonism plus=no response to treatment with Dopamine it is thought to be genetic and cause degeneration and changes in the neurotransmiters in basal ganglia and other locations in brain--less understood compare to parkinson disease.
Do not know. Although seemingly related to parkinson's disease, and categorized as a "movement disorder", there does not seem to be a lot of information on risk factors or any techniques to prevent or even fully mitigate once it starts. It is incurable and progressive, and a nasty problem.

Good Rx available!! Dopamine meds for physical parkinsonism: Azilect (mao-b selective inhibitor) & sinemet +/- Comtan (stalevo (carbidopa and levodopa and entacapone) is both together). Tailor rx & watch for side effects. Avoid Dopamine agonists (requip xl/mirapex er/neupro)--too side effect prone for psp patients. For dementia: namenda, paired with Exelon patch or aricept. For psychosis: seroquel or clozaril. Remember, response is variable, but worthwhile. Read more...
