Summary: Through tests of pupil dilation and cornea behavior, the authors were able to use data analysis to discover those who were probable to have Alzheimer's disease and/or dementia. By using measurements of pupils and range of motion, pupillary responses show notable differences and predict the sicknesses.
Key Facts:
"Even if the reported difference between patients with AD and normal subjects proves to be a result of non-pharmacological factors, it may still represent a potentially valuable diagnostic tool."
"Several letters suggest that our finding may have been a result of an increased permeability of the cornea in patients with probable AD. We agree that a change in permeability is one possible
mechanism."
