Dementia is the name given to a group of symptoms that are linked to a decline in brain function, according to the NHS.
Symptoms include memory loss, difficulty following a conversation, and difficulty with language.
There’s no cure for dementia. But, some treatments and lifestyle swaps could help to reduce symptoms.
Exercise could help to prevent dementia, said nutritionist Cassandra Burns.
“Getting the balance right is important when it comes to exercise,” said Burns.
“Exercise stimulates the release of endorphins, which makes us feel happy and relaxed afterwards.
“Getting enough exercise can also help us sleep better, which then helps us to cope with stress.”
You could also prevent dementia by making these lifestyle changes.
“Walking in a new park or taking up line dancing fires up new neural pathways that keep your brain in touch.
“Needing to remember the steps in a dance is also a wonderful workout for your brain – learning the flow and rhythm of the music stimulates cognitive activity, while learning and performing the steps is great for both your memory and your physical fitness.”
Get extra sleep
Sleep deprivation increase the risk of Alzheimer’s disease.
Having shorter amounts of sleep means there’s less time for the body to get rid of toxins in the brain, and may lead to the condition.
Take B vitamins
B vitamins play an important role in fighting against age-related cognitive decline.
You can top up on B vitamins by eating more fruit and vegetables.
Add whole grains, meat and fish to your diet to boost your B vitamin intake.
Sleep on your side
Nutritionist Dr Marilyn Glenville said: “When you sleep on your side, your body seems more able to remove the build-up of so-called ‘brain waste’ chemicals, such as beta-amyloid proteins, that are thought to contribute to dementia and other neurological diseases such as Parkinson’s.”
Enjoy the sunshine
Sunlight helps to boost the amount of vitamin D in the body.
Vitamin D receptors have been found in areas of the brain responsible for creating new memories and processing information.
Get at least 30 minutes of sunlight everyday to optimise your vitamin D levels.
Watch out for diabetes symptoms
Long-term cognitive decline is worse in type 2 diabetes patients.
Preventing diabetes could also help to lower your risk of dementia.
