Alzheimers Disease International (ADI) has used models to predict that the number of people living with dementia worldwide could treble by 2050. 44 million people are estimated to be living with the disease currently, but the figure could increase to 135 million by 2050.
38% of known cases occur in rich countries at present but, with demographic changes and increasing life-expectancies, it is predicted that by 2050 71% of dementia patients will be those living in poor and middle-income countries.
These figures, and a fresh report on the global challenge of dementia, have been released ahead of the G8 Dementia Summit which is to be held in London next week.
