Eye tests ‘could spot’ early Alzheimer’s disease

admin Interesting Info

New research suggests eye checks could be used to identify those with early Alzheimer’s disease long before any symptoms.

Simple regular eye tests could be used to identify Alzheimer’s disease at a very early stage, new research suggests.

Early trials of two different techniques show that a key biomarker for the disease can be identified in the retina and lens of the eye. Both methods were able to distinguish between healthy volunteers and those likely to be suffering from Alzheimer’s patients with a high level of accuracy. Experts said the findings could be a “game changer” in treatment of the condition.

So far attempts to find drugs to halt progression of Alzheimer’s disease have failed because patients receiving treatment already suffered too much damage to the brain.
