Dementia symptoms include memory loss, confusion, mood changes and difficulty moving.

Signs of the neurodegenerative conditions tend to get worse over time. In the latter stages of dementia, patients are less able go about their everyday lives, and may lose a lot of their communication skills.

The condition isn’t a normal part of ageing, and you could lower your risk by making simple lifestyle change.

“Research has not yet discovered a cure for dementia, and doctors are not certain of an exact method of preventing the disease,” said elderly care home Forest Healthcare.

“But, changes to diet, exercise and daily routine can reduce the risk factors.”

Eat omega-3 fats

Omega-3 fatty acids could lower your risk of dementia, the care home said.

Salmon and sardines are particularly rich in the fats, so make fish for dinner at least twice a week.

“Nuts and seeds are also rich in omega-3 goodness and taste delicious when added to your breakfast cereal,” said Forest Healthcare.

Exercise regularly

Exercising when you’re older is even more beneficial than when you’re younger, the care home said.

“Exercising at least three or four times a week reduces the risk of heart disease, which is a known contributing factor to developing dementia.”

Watch your weight

Obesity and being overweight have been linked to both high blood pressure and diabetes, and it could also be causing dementia.

Ask your GP about your ideal body mass index if you’re worried, said Forest Healthcare.

Be social

“Loneliness has been linked to early signs of dementia and cognitive decline, which is why it is important to socialise,” said the care home.

“Why not become a member of your local gym and try out some of the group exercise classes? After all, we are not solitary creatures, life is better shared.

“Spending time with other people is good for the body and the mind.”

Stimulate your mind

Continuous learning in later life could help to prevent dementia.

Learning a new language or musical instrument will help to preserve memory, Forest Healthcare claimed.

“Think of it like taking your brain to the gym,” it said.

Sleep well

Dementia risk could be increased by disrupted sleep, or insomnia.

Regular exercise and a healthy diet could improve your sleep patterns.

Speak to your GP if you’re having trouble sleeping.

Relax

Chronic stress could cause dementia in later life, but regular relaxation activities could help you to feel more relaxed.

Try quiet reading, light exercise, or listening to calming music, Forest Healthcare advised.
