About dementia
Dementia is the term we use for a group of symptoms, caused by different illnesses, that affect the brain.
In some languages there is no word for dementia, which is why it is so important to raise awareness of the illnesses and symptoms.
Dementia makes it harder for a person to think, talk, or remember things.
The most common symptoms of dementia are:
- memory loss
- confusion
- problems with speech
- problems with understanding
To find out more about the symptoms of dementia, visit the NHS website.
If you are worried about your memory, Alzheimer's Society dementia advisers provide one-to-one support.

Dementia cannot be reversed which is why it is important to keep your brain healthy.
Young-onset or early-onset dementia
Dementia can affect people of any age, but it is more common in people aged over 65 years.
When symptoms begin before the age of 65 years, it is known as young-onset or early-onset dementia.
Find out more about young-onset dementia symptoms and how to cope after a diagnosis of young-onset dementia.
Learning disabilities and dementia
People with a learning disability are more likely to get dementia at a younger age and may find that their dementia gets worse more quickly.
This can be due to delays in getting a diagnosis.
