What is dementia?
Dementia is a common condition that affects over 850,000 people in the UK and the number is set to rise to 1 million by 2021 according to the Alzheimer's Society website.
Dementia describes symptoms that may include memory loss, difficulties with thinking, problem-solving or language and sometimes changes in mood or behaviour.
Dementia is not a natural part of ageing and it occurs when the brain is affected by a disease or a series of strokes.
There are many types of dementia, with the most common types being Alzheimer's disease and vascular dementia and some people have a combination of these, known as mixed dementia.
