answer:I don’t know if it is the first study to demonstrate the ability of stems cells to repair neurons bu all research like this gives hope. I have a brother with schizophrenia, a cousin with severe cerebral palsy, another cousin with MS and had an uncle who died several years ago after a 30 year battle with Parkinson’s disease. Any kind of research that might find cures, or ways to mitigate the damage of these horrible diseases is more than welcome by me. I know I didn’t answer your question but I was concerned that you seem to think there are so many cynics out there. I am most certainly not one of them.
