Study finds 10% of over-70s in UK could have Alzheimer’s-like changes in brain

Findings mean more than 1 million people could meet NHS criteria for treatment with anti-amyloid drugs

One in 10 people in the UK aged 70 and older could have Alzheimer's-like changes in their brain, according to the clearest, real-world picture of how common the disease's brain changes are in ordinary, older people.

The detection of the proteins linked with the disease is not a diagnosis. But the findings indicate that more than 1 million over-70s would meet Nice's clinical criteria for anti-amyloid therapy - a stark contrast to the 70,000 people the NHS has estimated could be eligible if funding were available.
