New research suggests 'eye tests could detect Alzheimer's'

Regular eye tests could in future be used to diagnose early-stage Alzheimer's, new research suggests. Early trials of two different techniques show that a key Alzheimer's biomarker can be identified in the retina and lens of the eye.

'Cheap' Alzheimer's eye tests an 'important step'

The development of a quick, cheap, non-invasive test to detect Alzheimer's would be an important step in helping people to receive an early diagnosis, the head of science at Alzheimer's Research UK has said, after new research suggests that regular eye tests could help detection.

It is difficult to diagnose Alzheimer's disease accurately and, in many cases, by the time the symptoms have developed, damage has already been going on in the brain for a number of years.

It is too soon to determine whether these types of tests will be useful for diagnosis of dementia and we would need to see the results of larger trials before drawing any firmer conclusions.
