10 facts on dementia

Updated April 2017

Dementia is a syndrome, usually of a chronic or progressive nature, caused by a variety of brain illnesses that affect memory, thinking, behaviour and ability to perform everyday activities.

The number of people living with dementia worldwide is currently estimated at 47 million and is projected to increase to 75 million by 2030. The number of cases of dementia are estimated to almost triple by 2050.

Dementia is overwhelming not only for the people who have it, but also for their caregivers and families. There is a lack of awareness and understanding of dementia in most countries, resulting in stigmatization, barriers to diagnosis and care, and impacting carers, families and societies physically, psychologically and economically.
