I typically hesitate posting medical journals or studies on this blog because I assume that those reading it probably don't have the time to sift through the jargon and medical terminology. However, this is some exciting news on the Alzheimer's front that I think needs to be shared. Out of respect for everyone's time, I will briefly summarize my understanding of the findings as well as post the actual article below.
Scientists have previously identified a gene, APOE4, which is known to increase the risk of developing Alzheimer's later in life. Individuals who possess one copy of the gene are three times more likely to develop Alzheimer's and those who possess more than one copy are ten times more likely. That discovery was made in 1991. This is not news.
The exciting news is the recent discovery that people who have the APOE4 gene experience changes in the way that 215 other genes express themselves before they actually develop Alzheimer's. This is exciting for a number of reasons. Mostly, it means that scientists can begin to look into early ways to intervene BEFORE symptoms appear. All of the treatment options for people with Alzheimer's currently are behind the proverbial eight ball. Once you develop the disease THEN doctors look into ways that they can slow the progression. There is currently no feasible way to predict who will get it. There is no way to prevent people from acquiring it. There is no way to cure people who have it. In a world of gray skies and dim possibilities, this is finally some sunshine from behind the clouds.
