Scientists are developing a “30-second Alzheimer’s screening test” reported The Daily Telegraph. It said that such a test “could be available in as little as two years”.
This news was based on research that gave MRI scans to 428 healthy people in their forties to look for changes in the intensity of white matter lesions (the nerve fibres) in specific areas of the brain. The study found that these brain changes were each present in 0.4-20% of participants and that their presence in specific areas was linked to poorer performance in some cognitive tests. There were also differences in the way men and women were affected.
White matter changes have previously been associated with poorer performances on some cognitive tests in older individuals, and this research looked for a similar association in younger people. However, it is important to emphasise that this research has not developed a test for Alzheimer’s or dementia, as some newspapers have reported.
The population included in the study were healthy and their performance in cognitive tasks is likely to still be within the normal range.
Ultimately, it is not clear from this research if the observed changes in white matter intensity during middle age would actually lead to dementia or Alzheimer’s disease in later life. Read more: lanarkgazette.co.uk
