Research published today (Friday 21 August) in The Lancet Neurology journal indicates that the number of people with dementia in some Western European countries is stabilising.
The reason(s) why rates of dementia may be levelling-off, or even falling, is not certain; but improvements in general wellbeing and ongoing work towards the reduction of risk factors for dementia (which include diabetes, cardiovascular disease, stroke, hypertension, depression, low educational attainment, smoking, obesity and physical inactivity) have been suggested.
According to the researchers, although the decrease in dementia occurrence is a positive sign, dementia care will remain a crucial challenge for many years because of population ageing.
