Dementia is an umbrella term for a range of progressive conditions that affect the brain. Each type of dementia stops a person’s brain cells (neurones) working properly in specific areas, affecting their ability to remember, think and speak. Dementia affects people in different ways, depending on the type of dementia. The impact can be physical, emotional and psychological, and can also profoundly change the practicalities of everyday life.
Dementia can affect a person at any age but it’s more common in people over the age of 65.
There are over 200 subtypes of dementia. The most common are Alzheimer’s disease, vascular dementia, Lewy body dementia, frontotemporal dementia and mixed dementia.
By 2025, it’s estimated that over one million people in the UK will have a diagnosis of dementia – and almost all of us will know someone living with the condition.
