Alzheimer's and Dementia
Worldwide, 55 million people are living with Alzheimer's and other dementias.
Alzheimer’s disease is a degenerative brain disease and the most common cause of dementia. Dementia is not a specific disease. It's an overall term that describes a group of symptoms.

Someone in the world develops dementia every 3 seconds. There are over 55 million people worldwide living with dementia in 2020. This number will almost double every 20 years, reaching 78 million in 2030 and 139 million in 2050. Much of the increase will be in developing countries. Already 60% of people with dementia live in low and middle income countries, but by 2050 this will rise to 71%. The fastest growth in the elderly population is taking place in China, India, and their south Asian and western Pacific neighbours.
