The Eyes Have It? A New Tool To Detect Alzheimer's?

USA Today ran a story, Can this eye scan detect Alzheimer's years in advance? This short article explains that according to scientists "early indicators of Alzheimer's disease exist within our eyes, meaning a non-invasive eye scan could tip us off to Alzheimer's years before symptoms occur... It turns out the disease affects the retina — the back of the eye — similarly to how it affects the brain, notes neuroscience investigators at Cedars-Sinai Medical Center in California. Through a high-definition eye scan, the researchers found they could see buildup of toxic proteins, which are indicative of Alzheimer's." The study on which this article is based was published in the Journal of Clinic Investigation.  Retinal amyloid pathology and proof-of-concept imaging trial in Alzheimer’s disease is downloadable as a pdf by clicking here. The 19 page article offers this intriguing statement. "Such retinal amyloid imaging technology, capable of detecting discrete deposits at high resolution in the CNS, may present a sensitive yet inexpensive tool for screening populations at risk for AD, assessing disease progression, and monitoring response to therapy." (Warning-there are a lot of detailed photos of eyes in this article).
