The World Alzheimer Report 2015: ‘The Global Impact of Dementia: An analysis of prevalence, incidence, cost and trends’ finds that there are currently around 46.8 million people living with dementia around the world, with numbers set to increase to 74.7 million by 2030 and 131.5 million by 2050. There are over 9.9 million new cases of dementia each year worldwide, implying one new case every 3.2 seconds.
The report shows that the current annual societal and economic cost of dementia is US $818 billion, and it is expected to become a trillion dollar disease in just three years’ time. The findings show that the cost of dementia has increased by 35% since the 2010 World Alzheimer Report estimate of US $604 billion.
This means that if global dementia care were a country, it would be the 18th largest economy in the world, and would exceed the market values of companies such as Apple (US $742 billion) and Google (US $368 billion).
The report updates Alzheimer’s Disease International’s (ADI) data on dementia’s global prevalence, incidence and cost, highlighting dementia’s increasing impact on low and middle income countries (LMICs).
It is estimated that 58% of all people living with dementia today reside in LMICs, a proportion that is anticipated to rise to 68% by 2050, driven mainly by population growth and an ageing global population.
ADI is urging policy makers around the world to approach the issue with a broader agenda and a wider representation of countries and regions, particularly those in the G20 group of nations. A key recommendation of the report calls for a significant upscaling of research investment into care, treatment, prevention and cure.
