The disease affects the brain, and more than 520,000 people in the UK are currently affected by the condition.
A hallmark of Alzheimer's disease is the build-up of amyloid beta proteins in the brain, which causes plaques.
The plaques then result in the loss of connections between nerve cells in the brain - and ultimately the death of those cells and a loss of brain tissue.
Though there is currently no cure for the disease, but these steps put together by Forest Healthcare could help prevent the disease.
1. Eat salmon
Eating omega-3 rich foods like salmon has been proven to help prevent the build up of amyloid beta proteins on the brain.
"Research has proven that the DHA in omega-3 fats reduces the risk of dementia," said Chris Salter, group support manager at Forest Healthcare.
"Salmon and sardines are particularly high in DHA, 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."
2. Exercise more
You've heard it several times before, regular exercise is the key to a healthy life and dementia is no different.
"Regular exercise has been known to cure most ailments, and when you are older it is even more beneficial," Chris 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."
3. Watch your weight
An expanding waistline will do you no favours in staying healthy as you age.
"High blood pressure and type 2 diabetes are typically caused by being overweight, and have been linked to causing dementia," Chris added.
"If you are worried about your weight ask your GP about your ideal BMI, and find out if you need to lose a bit of winter padding."
4. Stub it out
If the multiple cancer, heart disease and stroke risks linked to smoking aren't enough to make you quit, perhaps Alzheimer's is.
Chris said: "Recent research discovered that smokers over the age of 65 have an 80 per cent higher risk of developing dementia than non-smokers.
"Stopping smoking doesn’t just benefit your lungs.
"A smoke free lifestyle improves circulation in the brain which makes a happier, healthier, mind."
5. Be social
An active social life is not only good for your mental health, it can stave off Alzheimer's.
"Loneliness has been linked to early signs of dementia and cognitive decline, which is why it is important to socialise," Chris said.
"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."
6. Train your brain
You've heard the saying - if you don't use it, you lose it.
Your brain is no different.
"Continuing learning and stimulating your mind in later life could help to prevent dementia," Chris explained.
"Learning a new language, musical instrument or craft are all fun and intellectually stimulating activities which will help to preserve your memory.
"Think of it like taking your brain to the gym."
7. Get plenty of sleep
If you need an excuse to head home for an early night, this is it.
Chris said: "Disrupted sleep patterns and insomnia have recently been suggested as risk factors for dementia.
"Regular exercise and a healthy diet can improve your sleep patterns.
"If you are having problems sleeping speak to your GP."
8. Stress less
This one may be easier said than done.
But, if you can, managing your stress levels will help protect you from dementia.
"Chronic stress takes its toll on the brain, and could cause dementia in later life," Chris said.
"Regular relaxation activities such as quiet reading, light exercise or listening to calming music and even meditation could do wonders for your stress levels.
