I don't have any friends with Alzheimer's yet but some of their parents have had it. Researchers have come up with 2 drugs that will stop the spread of Alzheimer's and have tested it on animals with great success. It won't cure anyone that already has advanced Altzheimer's but if caught early will stop it from getting worse. The drugs are LM11A and LM11A-32(ALSO CALLED C32). I'm not a doctor or medical expert, I read about this in a medical magazine at my eye doctors office. I also read that Alzheimer's is hereditary.
