Language. Dementia is a group of symptoms. It’s caused by different diseases that damage the brain. The symptoms get worse over time and include: Dementia is progressive, which means symptoms may be relatively mild at first, but they get worse over time. There are many types of dementia but Alzheimer’s disease is the most common. The next most common
is vascular dementia. Dementia is not a natural part of aging. It is caused when a disease damages nerve cells in the brain. Nerve cells carry messages between different parts of
the brain, and to other parts of the body. As more nerve cells are damaged, the brain becomes less able to work properly. Dementia can be caused by many different diseases. These diseases affect the brain in different ways, resulting
in different types of dementia. Around 19 out of 20 people with dementia have one of four main types. Dementia affects everyone differently, however each type has some common early symptoms. A person may also have mixed
dementia where they have symptoms of more than one type. Alzheimer’s disease is the most common type of dementia. For most people, the first signs of Alzheimer’s are problems with their memory, thinking, language or perception. Read our information on Alzheimer’s disease Vascular dementia is the second most common type of dementia. Common early signs of vascular dementia include problems with planning or organising, making decisions or solving
problems. Read our information on vascular dementia Dementia with Lewy bodies (DLB) is caused by Lewy body disease. Symptoms of DLB include having difficulties staying focused, experiencing
delusions, and problems with movement and sleep. It is closely related to Parkinson’s disease. Read our information on dementia with Lewy bodies (DLB) Frontotemporal dementia (FTD)Frontotemporal dementia (FTD) is one of the less common types of dementia. It is sometimes called Pick's disease or frontal lobe dementia. Common symptoms of FTD include changes to personality and behaviour and/or difficulties with language. Read our information on frontotemporal dementia (FTD) What are the symptoms of dementia?Each person experiences dementia in their own individual way. Different types of dementia also tend to affect people differently, especially in the early stages. However, there are some common early signs and symptoms of dementia. These include:
With some types of dementia, the person may have difficulty knowing what is real and what isn’t. They may see or hear things that are not really there (hallucinations), or strongly believe things that are not true (delusions). However, having symptoms like memory problems does not always mean a person has dementia. Dementia-like symptoms can be caused by other conditions, such as:
Dementia is progressive, which means symptoms may be relatively mild at first, but they get worse over time. A person may also experience new symptoms as their dementia progresses. Read about the later stages of dementia Who gets dementia?There are currently around 900,000 people in the UK living with dementia. It mainly affects people over the age of 65. The likelihood of developing dementia increases significantly with age. One in 14 people aged over 65 has dementia. This rises to 1 in 6 for people aged over 80. Dementia can affect younger people too. This is often called young-onset dementia. Around 1 in 20 people with dementia are younger than 65. There are more than 42,000 people in the UK under 65 with dementia. Dementia is also more common among women than men. Why do some people get dementia and not others?It is not always clear why some people get dementia while others don’t. It can depend on a combination of age, genes, lifestyle and other health conditions. Most types of dementia are not passed down (inherited) from a parent to a child. There are a few genes that will cause dementia if they are passed from a parent to a child – known as ‘familial’ genes. However, familial genes are rare. The dementia diagnosis process can vary for everyone. Read more about the typical steps involved in getting a diagnosis, including what might happen if you are referred to a specialist.

This is because it may allow the person to get the right treatment, such as:
