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 50 million and will almost triple by 2050.
