Imagine driving in your car and suddenly not recognizing where you, you don’t remember where you were going and have no idea how to find your way home. What if you looked across the breakfast table at your spouse and no longer recognizing them? Or maybe you have to brace yourself every time you visit your parent, waiting for the day when they won’t know who you are. This is reality for the estimated 50 million (worldwide) Alzheimer’s suffers and their families.
For a world with an aging population, Alzheimer’s is a growing problem. Recent estimates suggest that 11% of people over the age of 65 have Alzheimer’s disease. For people 85 and older, that number increases to 32% (1).
Alzheimer’s disease is a devastating degenerative brain disease. It is the most common cause of dementia, and is characterized by a decline in cognitive skills such as memory, language skills, communication and problem solving abilities. These symptoms make it difficult for people with Alzheimer’s to perform everyday activities. It also is difficult to diagnose, even more difficult to treat, and, as of now, impossible to cure.

It is hard to undermine the role of cleanliness in disease prevention, both internally and externally. Within our body, the lymphatic system plays an important role in clearing the intercellular passages of large and potentially harmful toxic molecules and recirculate back into the blood stream. This enables the transport of these molecules to liver for inactivation and subsequent removal from the body. Therefore, lymphatic system prevents build-up of soluble proteins in the interstitial space. Typically, more metabolically active a cell is, more intricate is the lymphatic vasculature around it. This observation was in contrast to our scientific knowledge a few years ago, when we believed that due to the presence of the blood-brain barrier, there was no lymphatic system active in the brain. The brain, as we know, is highly active metabolically and the removal of harmful solutes and proteins from the neuronal vicinity is of utmost urgency. For a long time it was believed that cerebrospinal fluid (CSF), while coursing through the brain also removed cellular metabolite by products, apart from carrying nutrients to brain tissue, through a process known as diffusion. This is a rather slow process and it did not very well explain how large molecules such as proteins were removed from the interstitial place.
Recently, using two-photon imaging technique in live mice, scientists at Rochester discovered (1) that there is another vasculature functioning in the brain which circulates CSF to every corner of the brain much more efficiently, through bulk flow or convection.
