Alzheimer's 'detected by eye test'
Alzheimer's could be diagnosed through an eye test, according to a research development which could help those with long term care plans.
A study by eyecare specialist Optos discovered a "highly significant" association between changes in the retina and Alzheimer's disease.
The diagnostic test detected drusen, which are minuscule white or yellow spots on the retina.
According to Roy Davis, chief executive of Optos: "This latest study adds to a growing body of clinical data that supports our conviction that the optomap has a crucial role to play in the detection and monitoring of a number of diseases."
In other news, taking lithium supplements could slow down the development of Alzheimer's disease, according to scientists at the University of Sao Paulo in Brazil.
Researchers found that while all mild cognitive impairment patients experienced a reduction in cognitive function, it was slower in those who took lithium than the participants given a placebo.
