A scary disease indeed. I first heard about it when researching for a paper on an admiral. I wrote to a fellow officer and his wife replied that he had recently died of Althzeimer’s. This was in the early 80’s. Since then a friend contracted the disease, and he had just turned 50. Those of us in our 60’s await the outcome with baited breath!
Bans on drug testing on primates means that much of the research will no longer be done in the U.S. and Europe, so China and India will probably become the major developers of new drugs.
