There are a number of different types of dementia, and the most common in the UK is Alzheimer’s disease.
Diagnosing the condition early could help to slow down the condition’s progress.
Making some small lifestyle changes could lower your chances of developing Alzheimer’s in later life.
One of the key warning signs of dementia is suddenly using bad language.

“The signs of this form of dementia are different from those of normal age-related forgetfulness,” it said.
“Have you ever lost your house keys, or forgot where you parked the car? Relax. Occasional memory slips are natural.
“While you may be able to chalk off a few memory lapses to normal ageing, there are some common warning signs of Alzheimer’s disease.
“Wandering, becoming agitated, hiding things, wearing too few or too many clothes, becoming overly suspicious, engaging in unsafe behaviours, or using foul language, may be signs of Alzheimer’s disease, especially if a person hasn’t behaved that way earlier.”
Meanwhile, you could also be at risk of the neurodegenerative condition if you find it difficult to complete everyday tasks, it added.
Struggling to navigate your car journey to a common destination is one of the earliest warning signs of Alzheimer’s disease.
Some patients also struggle to organise a shopping list, or remember the rules of their favourite game.
But, again, it’s completely normal to need extra help as we get older, and it doesn’t necessarily mean that you have dementia.
There’s no certain way to prevent dementia from developing, but there are ways to lower your risk, said the NHS.
Eating a healthy, balanced diet should help to lower your chances of developing dementia.
It’s also important to do enough exercise. Everyone should aim to do at least 150 minutes of moderate-intensity activity every week.
There are around 850,000 people in the UK with dementia, and the condition affects one in every six people over 80 years old.
