tranylcypromine (Parnate): An effective neuroprotectant?

Hello,

There is a history of parkinsonism in my family.  I would like to take a neuroprotectant even though it's controversial whether parkinsonism is familial or not.  i do not want to take selegiline (Eldepryl).  i tried it once and it caused a variety of bad side effects.  i like Parnate but i don't know if Parnate is an adequate neuroprotectant.  i have read conflicting things about it on the Internet.

could someone tell me if Parnate makes as good a neuroprotectant as Eldepryl and, if so, what dose I should aim for daily to achieve neuroprotection that may prevent or delay the onset of Parkinson's disease if this is my fate?  Thanks.
