Q: As I am a retired nurse, I am always interested in new medical technology and new ways of diagnosing. I have recently heard of using the eyes to diagnose Alzheimer’s. When I did some research I didn’t find too much. I am thinking the information may be too new or I wasn’t on the right sites.

(this is in response to last week’s piece on lutein, eyes, and brain health)

We’d readily bet that the diagnostic criteria has to do with recording low levels of lutein in the eye (discernible by a visual examination of macular pigment optical density), and relying on the correlation between this and incidence of Alzheimer’s, but we’ve not seen it as a hard diagnostic tool as yet either—we’ll do some digging and let you know what we find! In the meantime, we note that the Journal of Alzheimer’s Disease (which may be of interest to you, if you’re not already subscribed) is onto this:
