Japanese researchers have determined that "arginine supplementation curbs Alzheimers disease pathology in animal models." The even better news is that arginine is commonly available, safe for human use, and occurs naturally in meats, nuts, dairy products, legumes, etc.
It remains to be seen if arginine is effective against Alzheimers in humans. Still, if I were concerned about the disease I would load up on OTC arginine as it is unlikely to be of harm. Hat tip to Instapundit for the link.
