What is dementia?
Dementia is a general term that is used to describe a set of symptoms caused by diseases of the brain.
Dementia is not a normal part of aging, although age is one of the risk factors for developing dementia. It affects one in six people over the age of 80. One in twenty people of those diagnosed with dementia are under the age of 65.
There are more than 850,000 people in the UK living with dementia, and this figure is expected to rise to more than 1 million by 2025. It is estimated that there are currently 670,000 unpaid family carers in the UK.
Dementia can be caused by many different conditions and diseases of the brain. It is thought that there are more than 100 different types of dementia.
The most common form of dementia is Alzheimer’s disease, with vascular dementia and dementia with Lewy Bodies other common forms of dementia. If you need information about types of dementia visit the Alzheimer’s Society website to find out more.
Every person with dementia will experience it in a different way and may present a range of symptoms. Depending on the type of dementia a person has, the symptoms may range from memory loss, difficulties with thinking and problem solving, to changes in mood, perception or behaviour.
