Dementia Risk in UK Declining? (BBC News / Lancet / NHS Choices)

Summary

The risk of older people developing dementia may be going down in the UK, according to epidemiological research published in the Lancet. A smaller proportion of older people living in Britain appear have the condition than experts would had predicted earlier, possibly due to improving public health.

The article compares dementia rates in people, born 20 years apart, in three areas of England (Cambridgeshire, Nottingham and Newcastle). Extrapolating from 1991 trends, experts had predicted that 8% of over-65s would have dementia by 2011, whereas the actual figures for 2011 indicated slightly over 6% had the condition.

Applied across UK, there may be 214,000 fewer cases of dementia than predicted; a 24% reduction to 670,000 people living in the UK with dementia (as opposed to the previous estimates of 800,000 – 900,000 people).

This could be because known risk factors for dementia are declining. Improvements in the management of cardiovascular disease may have resulted in a decreased risk of vascular dementia.
