4. Types of Dementia


There are over 200 sub types of dementia. 

Yep, that is a lot! 

Here we are going to focus on the 5 most common types to save you from learning things you might not need to know.

This is the most common type of dementia in the UK. It is a physical condition caused by changes in the structure of the brain resulting in a shortage of important chemicals that help with the transmission of messages. 

Alzheimer’s disease symptoms tend to develop gradually over time and can affect concentration, decision making and everyday living skills.
This is the second most common type of dementia. 


It is caused by problems in the supply of blood to the brain. This is commonly due to strokes or a series of small strokes, known as TIAs or Trans Ischemic Attacks which cause areas of cell damage to the brain.
Dementia with Lewy bodies is a progressive condition that affects movement and motor control. 

Memory is often less affected than with other types of dementia, but a person might experience sudden bouts of confusion which can change on an hourly basis. The person’s judgement may be affected and they can suffer hallucinations.  
Frontotemporal dementia is a progressive condition, which tends to affect younger people, usually aged 45 to 65 years, but can be younger, and can be difficult to diagnose. 

The region of the brain most affected is the frontal lobes. Frontotemporal dementia affects behaviour and personality, and this can cause dis-inhibition and inappropriate social behaviour. Eating patterns can also be affected, with people suddenly bingeing on food, especially sweet foods. 
It is possible to have not just one but two types of dementia. 

The most common is a combination of Alzheimer’s disease and vascular dementia, known as mixed dementia. 

A person with mixed dementia would experience a mixture of the symptoms associated with the types of dementia they have.

People with Down syndrome are more likely to get dementia and on average at a younger age than other people.
