The number of people affected by Alzheimer's disease is currently estimated at 26 million worldwide, with 700,000 cases in the UK alone. Research presented at the International Conference on the Prevention of Dementia in Washington DC showed that this figure will rise to over 106 million cases by 2050.

The research author Professor Ron Brookmeyer said: ‘We face a looming global epidemic of Alzheimer's disease as the world's population ages.'

'By 2050, one in 85 persons worldwide will have Alzheimer's disease. However, if we can make even modest advances in preventing Alzheimer's disease or delay it progression, we could have a huge global public health impact.'

Professor Brookmeyer highlighted that the greatest increase in cases will occur in Asia. By 2050 the number of cases there will account for 59 per cent of all cases worldwide.
