Dementia is a growing health issue, not just in New Zealand but also around the world. It is currently estimated that approximately 70 000 New Zealanders have dementia. About 1 in 100 people in their 60s are estimated to be affected and 1 in 3 people over the age of 90. The number of people living with dementia is expected to rise sharply in the next few decades as our growing ageing population lives longer.
