Scientists say they can predict memory fading in your 70s by looking at tests you took at eight

Scientists say they can tell how badly your memory will fade six decades before it happens. Participants who scored poorly on mental tests at the age of eight were more likely to have thinking and memory problems by the time they reached 70. Researchers said their findings suggest subtle cognitive differences could be a marker for dementia before the symptoms appear. However, the results did not investigate whether cognitive skills in childhood are linked to the risk of developing dementia. Education and income, assessed by occupation at the age of 53, was also shown to be an indicator of how brain power declines in your 70s.
