The Global Impact of Dementia: An analysis of prevalence, incidence, cost and trends found that there are currently around 46.8 million people living with dementia around the world, with numbers projected to nearly double every 20 years, increasing 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 number of people living with dementia worldwide today is estimated at 44 million, reaching 76 million by 2030 and 135 million by 2050. The global cost of dementia was estimated in 2010 at $604 billion USD and is only set to rise. Given this epidemic scale, and in the absence of a cure, it is crucial that we focus on risk reduction.
