Treating and caring for people with dementia currently costs the world more than US$ 604 billion per year.
Nearly 35.6 million people live with dementia worldwide. By 2030 this number is expected to double (65.7 million) and more than triple by 2050 (115.4 million). Dementia affects people in all countries, with more than half (58%) living in low- and middle-income countries. By 2050, this is likely to rise to more than 70%.
