The approach AXON is using is bound to fail. Check out AVXL for Alzheimer's and other nuerodegenerative diseases. Up over 25% today on Michael J Fox funded Parkinson's mouse study. It seems to be working in many different areas and is very safe.
Certainly starting to look that way. My money is on AVXL, impressed with their results and CEO. My hope is that one or both succeed in AD and easing the suffering.
