Dementia Worldwide

The global impact of dementia
Key facts

  • Every 3 seconds, someone in the world develops dementia.
  • There were an estimated 50 million people worldwide living with dementia in 2017. This number will almost double every 20 years, reaching 75 million in 2030 and 131.5 million in 2050.
  • Much of the increase will be in low and middle income countries. Already 58% of people with dementia live in low and middle income countries, but by 2050 this will rise to 68%.
