The new report is released on World Alzheimer's Day and claims that dementia prevalence will nearly double every 20 years, to 65.7 million in 2030 and 115.4 million in 2050.

Alzheimer's Society's comment:

'This data shows the scale of the challenge. Dementia is a growing issue with one million people in the UK set to develop the devastating condition in the next 10 years. This worldwide problem needs a response from every nation and the UK government must play a key part.

We must see public awareness campaigns; improvements in dementia care and an increase in funding for dementia research. With the right investment, dementia can be defeated.'
