Dementia is a progressive condition that affects memory, thinking and behaviour. Learn more about what dementia is, the symptoms, risk factors and the different stages.
Doctors typically use the word ‘dementia’ to describe common symptoms – such as memory loss, confusion, and problems with speech and understanding – that get worse over time. Each type of dementia stops a person’s brain cells (neurones) working properly in specific areas, affecting their ability to remember, think and speak.
What are the main signs and symptoms of the most common types of dementia. Be aware that everyone has their own experience of dementia, and the signs and symptoms may vary between people.
Dementia can be caused by many factors, including genetics, brain changes, other health conditions and lifestyle choices.
It can be helpful to think of dementia progressing in three stages - early, middle and late.
