Five Things You Should Know About Dementia
Dementia is not a natural part of ageing
We all forget a name or a face sometimes. Especially as we get older. But dementia is something different.
Memory problems are one of a number of symptoms that people with dementia may experience. Others include difficulties with planning, thinking things through, struggling to keep up with a conversation, and sometimes changes in mood or behaviour.
Dementia is not a natural part of ageing and it doesn’t just affect older people. Over 40,000 people under 65 in the UK have dementia. This is called early-onset or young-onset dementia.
Dementia is caused by diseases of the brain
Diseases such as Alzheimer’s disease cause nerve cells to die, damaging the structure and chemistry of the brain.
Other types of dementia include:
- vascular dementia (caused by problems with blood supply to the brain)
- mixed dementia (usually Alzheimer’s disease and vascular dementia)
- dementia with Lewy bodies
- frontotemporal dementia (including Pick’s disease)
Alzheimer’s disease tends to start slowly and progress gradually. Vascular dementia after a stroke often progresses in a ‘stepped’ way. This means that symptoms are stable for a while and then suddenly get worse.
It's not just about losing your memory
When most people hear the word dementia, they think of memory loss.
And it does often start by affecting the short-term memory. Someone with dementia might repeat themselves and have problems recalling things that happened recently. But dementia can also affect the way people think, speak, perceive things, feel and behave.
Other common symptoms include:
- difficulties concentrating
- problems planning and thinking things through
- struggling with familiar daily tasks, like following a recipe or using a bank card
- issues with language and communication, for example trouble remembering the right word or keeping up with a conversation
- problems judging distances (even though eyesight is fine)
- mood changes and difficulties controlling emotions. For example, someone might get unusually sad, frightened, angry, easily upset, or lose their self-confidence and become withdrawn.
Symptoms of dementia gradually get worse over time. How quickly this happens varies from person to person – and some people stay independent for years.
People can still live well with dementia
Although there is no cure for dementia, scientists and researchers are working hard to find one.
Until that day comes, support and treatments are available that can help with symptoms and managing daily life. These can allow people with dementia to lead active, purposeful lives and carry on doing the things that matter to them most.
