“Despite the widely held belief that dementia is destined to rise exponentially as global populations age, experts believe that, in the developed world at least, the prospects of avoiding dementia are stronger than they were a generation ago.

A study published in 2020, which drew together multiple pieces of research to track the health of almost 50,000 over-65s, showed the incidence rate of new cases of dementia in Europe and North America had dropped 13 per cent per decade over the past 25 years — a decline that was consistent across all the studies.”
