The truth behind the myths

Information on what is and isn't beneficial in the prevention and treatment of dementia isn't always reliable. Here, we dispel some of the more common myths and help you to separate fact from fiction.

Can using aluminium saucepans affect the risk of developing Alzheimer's?

No. Despite sporadic publicity, there is no convincing evidence that cooking with aluminium saucepans increases the risk of developing Alzheimer's.

Is there any benefit in taking folic acid and vitamin B supplements to protect against dementia?

We don't know yet, but don't do it without first checking with your GP. It is too early to say and, indeed, for some people taking these supplements is not appropriate. It has also been suggested that other vitamins might help to prevent the brain damage caused by dementia, but more research is needed to assess whether this is actually the case. Before taking supplements it is important to consult your GP.

The Alzheimer's Research Trust has launched the largest ever study in the world probing the link between B vitamins and Alzheimer's disease - sign up to our e-Newsletter for updates on this and other important research.

Is it true that people who follow a healthy lifestyle reduce the risk of developing dementia?

Yes. Research tells us that people who enjoy a healthy lifestyle - by eating a well-balanced diet, not smoking and taking regular exercise - lessen their chances of developing dementia. Recent research has shown that being healthy in mid-life can help lower our risk of developing dementia as we age.

Since several possible risk factors for Alzheimer's are also linked to heart disease and stroke, it is possible that a healthy lifestyle to protect against these diseases could also help prevent dementia.

Does eating meat have any connection with developing Alzheimer's?

There is no convincing proof that eating meat is liked to developing Alzheimer's.

Can Ginkgo biloba help people with dementia?

No. Unfortunately, the latest evidence shows that Ginkgo biloba has no benefit for people with dementia. One of the longest and most rigorous studies yet on Gingko biloba found it does not slow the progression of dementia and does not affect quality of life or cognitive skills. The findings provide the most robust evidence to date that, sadly,  Ginkgo biloba is not an effective treatment for dementia. Another recent, large study showed that Ginkgo biloba does not prevent dementia.

Can caffeine, curcumin, garlic, sage, lemon balm or ginseng have a positive effect on Alzheimer's disease?

We need to do more research before we'll know. There have been suggestions that they can have an effect, but results are mixed and further studies are needed before any firm conclusions can be made.

Should I take HRT to protect against dementia?

No. Studies into a link between Alzheimer's and hormone replacement therapy (HRT) have been inconclusive and more research is needed. In general, women are not advised to start HRT as a means of protecting against dementia, because this treatment can have side-effects, and may possibly increase the risk of heart disease or stroke.

Should I take aspirin to prevent Alzheimer's?

No. Unfortunately, there is no sure way to prevent Alzheimer's. Medicines known as non-steroidal anti-inflammatory drugs (NSAIDs), which include aspirin and ibuprofen, have been linked to a reduced risk of dementia, but they can also cause dangerous side-effects, including stomach ulcers and kidney problems. More research is needed in this area and it is not advisable to take these drugs to try to protect against dementia.
