The beta-amyloid plaques that kill the neural tissue of people with Alzheimer’s disease accumulate in retinal tissue before other parts of the brain.  These plaques usually develop in the brain before there are symptoms of cognitive decline.  Since there is no way to detect plaques in the brain, detection in the retinas would be the [...]

A recent study in the Journal of Neuroscience has provided a new possibility for detecting Alzheimer’s disease (AD) early: loss of the ability to smell. The research used mice that were genetically engineered to develop the signature amyloid plaques that occur in AD. In the course of the research, the scientists noticed that the plaques [...]
