Given the convincing evidence of αSyn pathology and TDP-43 pathology in the retina, [116, 117, 138, 139] further research into a specific distinction between p-τ, αSyn, and TDP-43 pathologies in the retina could lead to a better diagnosis of co-pathologies and, by doing so, to a better stratification of AD allowing the development of personalized treatment strategies depending on the spectrum of co-pathologies. Here, TARDBP is linked to Alzheimer disease.
