Kenneth L. Davis a highly qualified scientist and expert on Alzheimers, wrote an article for Forbes: How To Accelerate The Search For Alzheimer's Drugs Click the link to read it.
To summarize some of the article... Davis points out the current hopefulness in some areas of progress, but the majority of the article lists the difficulties with the disease itself, the long process researchers have to go through, the business and legal issues that stand in the way of pharmaceutical companies using the best and most direct processes available. And how Congress could make things much better.
The article is reality. It is not good news. You need to read it though to learn why WE must raise awareness and put political pressure on our government to make changes and remove roadblocks to finding a cure.
