Research shows dementia rates falling by 15% per decade over last 30 years

The risk of developing dementia is falling, thanks to lifestyle improvements such as reductions in smoking, new research has found. Researchers have said that while the overall number of cases is rising due to the population living longer, an individual’s chances of having the disease is going down | Alzheimers Research UK

International experts have presented research indicating that dementia incidence rates may be falling by up to 15% decade on decade. Analysing data from seven population-based studies in the United States and Europe, Prof Hofman and a global team of researchers set out to determine changes in the incidence of dementia between 1988 and 2015.

Of 59,230 individuals included in the research, 5,133 developed dementia. The rate of new dementia cases declined by 15% per decade, a finding that was consistent across the different studies included in the analysis.

The findings will be discussed at the Alzheimer’s Research UK Conference 2019 in Harrogate.
