Simple eye scan could detect Alzheimer's

Eye tests could be detailed enough to pick up on early signs of Alzheimer's disease، according to scientists.

Researchers say a new type of scan for the eye can show if tiny blood vessels in the back of the eye are changing، and pick up on thinning of the retina.

These could be signs of looming damage in the brain which may lead to Alzheimer's، the most common type of dementia.

And the early test raises hope of patients being treated or making lifestyle changes years before the disease actually develops، potentially adding years to their lives.
The technique called Octa (optical coherence tomography angiography) could revolutionise treatment of the devastating neurological disorder.

Professor Sharon Fekrat، an ophthalmologist at the Duke Eye Centre in Durham، North Carolina، said: 'If we can detect these blood vessel changes in the retina before any changes in cognition، that would be a game changer.'

There are drugs which can relieve symptoms of Alzheimer's or slow it down، and they work most effectively in the disease's earliest stages.

Spotting the condition sooner could allow for better treatment، and people could be encourage to change their diet or exercise more to slow down or stop its progress
