An Alzheimer Disease International (ADI) policy brief entitled ‘The Global Impact of Dementia 2013-2050’ has revealed a staggering 17% increase in the number of people living with dementia, compared to the original ADI estimates in the 2009 World Alzheimer Report.

The first G8 Dementia Summit took place in London, UK, on 11 December. The summit will aim to identify and agree a new international approach to dementia research and policy. 

This Alzheimer Disease International brief for the summit reveals that the number of people living with dementia worldwide in 2013 is now estimated at 44 million, reaching 76 million in 2030 and 135 million by 2050.

The report also predicts a shift in the distribution of the global burden of dementia. Where previously high income countries have witnessed the strongest visible trends, it will now be low and middle income countries who will feel the heaviest burden. By 2050, 71% of people with dementia will live in low and middle income countries.
