One might think of the retina as an exposed part of the central nervous system, available for inspection, unlike the rest of it. One of the major challenges in the diagnosis, prevention, and treatment of neurodegenerative conditions is that it is difficult to establish what exactly is going on inside a living individual’s brain. Even modern imaging systems have considerable limitations in what can be seen. Thus a number of research groups, such as the one noted here, are attempting to find ways to make use of retinal structure as a readout for the broader state of the aging brain.

In almost 3,000 participants of the Rhineland Study aged between 30 and 94 years, the retina was assessed using <a href="https://en.wikipedia.org/wiki…
