These 3 drugs are practically the "last men standing" in late-stage trials after more than a decade of failed attempts to halt the mind robbing disease. If these drugs don't work, experts say drug companies may pull out of the field in frustration and leave the 35 million world-wide with dementia with little hope.

The interesting thing about these drugs is that they are not drugs in the traditional sense, they are antibodies (proteins made by the bodies immune system) designed to clear amyloid plaques in the brain. Scientists aren't even sure that amyloid even causes Alzheimer's, or that by removing it, symptoms will improve in those who have the disease, but there have been some hopeful signs that they are on the right track.
Everyone in the field is holding their breath in anticipation that something good will come of these results. Even a small effect will mean huge success, because that will mean the drug is working.
There has not been a drug made that has even helped symptoms in the past 9 years...let's all cross our fingers!
