Fears of Alzheimer’s explosion ‘overblown’, study finds

Scientists found that the proportion of British people aged 65 and above with dementia fell by more than a fifth in 2011 compared with what it was predicted to be a decade earlier.
Studies in other European countries show a similar trend. In Zaragoza, Spain, there was a 43% fall in the prevalence of dementia in men aged 65 and older between 1987 and 1996, and dementia incidence had also declined in Sweden and the Netherlands.
