A simple mental test could predict future disorders of the brain, according to new research.
Researchers at the Australian National University and Brunel University, London, used a computer-based test which can calculate the risk of future dementia in middle-aged participants.
The study found minute white-matter lesions on the brains of adults aged 44-48 in the area similar to those diagnosed with Alzheimer's.
Participants who had lesions in the brain tended to struggle more with particular memory skills during the testing.
Results, published in the journal PLoS One indicate that the decline in the brain thought to lead to Alzheimer's disease may begin much earlier than initially predicted.
Professor David Bunce, who led the study, said that although it is not certain that the participants with legions will develop dementia in later life, the results are still significant.
"If the findings are repeated in laboratories elsewhere, the study lays open possibilities for screening, early detection and intervention in healthcare settings," he said.
This comes after reports from the University of Caroline, Berkeley, suggesting that if brain injury occurs in the part of the brain which controls memory or attention, other sections of the brain can take over.
