I admit it is not 100 % sure to prove neuroprotectiveness. I read that all patients were getting Azilect + some other stuff they individually decided to take. This messes up the results a bit. But I wouldn't give up hope and say Azilect could not be a neuroprotector. The several tests indicate neuroprotection. If this neuroprotection can be caused by random effects, like personal choice of meds ... then wouldn't you expect that in some test the delay group could have had better scores ? This was not the case. Also, the the reason of failure to show neuroprotectiveness for the 2 mg case that is provided, doesn't seem to be unreasonable.

I am not saying that neuroprotectiveness of rasagiline is proven. But I do agree that there are indicators that indicate that it might be neuroprotective. As far as I read they are still doing tests on this and hope to prove neuroprotectiveness in 2013.
