What is dementia?  

Are you worried about your own or a loved one’s memory, changes in personality, behaviour, and language? 

Please make an appointment to see your GP to talk through any of your concerns. You may be referred to the memory service for further assessment and support. 

Dementia is a term used for a range of conditions that affect the brain. 

The brain is made up of nerve cells that communicate with each other by sending messages. 

Dementia damages the nerve cells in the brain so messages can’t be sent from and to the brain effectively, which prevents the body from functioning normally. 

It can affect a person at any age, but it is more commonly diagnosed in people over the age of 65. A person developing dementia before age 65 is said to have young onset dementia. 

There are over 850,000 people living with dementia in the UK and this is set to exceed one million by 2025.
