It is possible that a simple eye test could detect the early signs of dementia. US researchers have found that that the thinning of the outer retina indicates frontotemporal dementia which mainly effects the front and sides of the brain. It is hard to diagnose as it does not initially cause memory problems.
And like other types of dementia it tends to develop slowly and get worse over several years. It affects around 16,300 people or two per cent of all dementia cases.
Doctor Murray Grossman of the ‘University of Pennsylvania School of Medicine’ said, “We can administer appropriate treatments to patients who are likely to benefit.”
