Alzheimer's new research

According to new research, optical imaging can be used to find earlier diagnosis and intervention of Alzheimer's. Nerve cell damaging plaque that builds up in the brain also shows up in your retinas. Previous studies show that changes in the brain can occur years even decades earlier. Noninvasive brain imaging could not provide enough information on the changes unless it was an autopsy done. The retina is considered a better target for noninvasive imaging because it is part of the central nervous system. Past research have documented retinal abnormalities but this is the first to identity plaque build-up that could specifically diagnose Alzheimer's.
