Dementia is associated with a loss of general cognitive ability. There are many subtypes of this illness, with the most common being Alzheimer’s disease. Although the prevalence of dementia increases with increasing age, dementia is not a normal part of aging. Nationally there have been several key policies aimed at increasing the number of people diagnosed with dementia as estimates suggest that nationally only about two thirds of people with dementia have been diagnosed with the condition.

Dementia has a significant impact on the person and their support network, the mental and physical wellbeing of their family and carers is equally as important. People can live well with dementia provided they and their carers have good, timely and person centred advice, support and care. Getting a diagnosis is important to allow for arrangements to be put in place to help a person live well with dementia and plan for their future. Dementia prevention is the same as prevention for many other chronic diseases and an NHS health check is a means of identifying preventable risk factors.
