Scientists have devised a test that could identify individuals set out to develop Alzheimer’s disease at some point in the future.
Researchers at the University of York in the US They have made the discovery and hope that it could pave the way for early diagnosis of neurodegenerative disease.
participants were asked to complete four tasks that tested their motor skills and visual-spatial laptops cognitive dual screen. There were three groups – those who had been diagnosed with mild cognitive impairment or relatives had the disease, a control group of younger adults and people older – both of whom had no family history of the disease.
These tests involve moving the mouse in the other direction to a visual target on the screen. This meant that the individual’s brain had to think before and throughout their actions – and this was where the biggest difference between the first group and the other two was observed.
The research team – led by Professor of the faculty of health Lauren Sergio and doctoral student Kara Hawkins – discovered how 81.8 percent of individuals in the first group had difficulty in visual motor task it was the most cognitively demanding.
“In terms of being able to classify the risk of Alzheimer’s disease and low risk of Alzheimer’s disease high, we have been able to do that quite well using these cinematics measures,” said Mrs. Hawkins.
“This group had slower reaction time and movement time and less accuracy and precision in their movements.”
Although the results do not accurately predict who will develop the condition, they do indicate how there are changes in the brains of those with mild cognitive impairment or relatives who have the disease.
The full results of this research can be seen in the Journal of Alzheimer’s Disease.
This study is encouraging because the earlier an individual may be diagnosed with some form of cognitive impairment, there is more hope that treatments are effective.
