We examine the truth behind the sale of supplements, vitamins, products and therapies that claim to prevent or treat dementia, or boost memory. It’s common to see advertisements online claiming to be a ‘miracle cure’ for dementia. Sometimes it can be difficult to know whether to trust these claims.

Unfortunately, any supplement or treatment available to purchase that claims to prevent, slow down or reverse dementia is extremely likely to be untrue.

However, while there is currently no cure for the diseases that cause dementia, there are drugs and non-drug treatments that can lessen a person’s symptoms.

Beware of false claims about 'treatments' for dementia

Receiving a dementia diagnosis can be a difficult time for the individual and their loved ones. Without the right care and support a person living with dementia feel vulnerable and more susceptible to targeted and aggressive marketing messages.

We’re concerned that people looking for information are not receiving the support or treatments they need following a diagnosis. Unsurprisingly, this leads to people looking online for alternatives. 

I’m worried about developing dementia – what can I do?

The root causes of the diseases that cause dementia are all different and very complex. For example, the cause of Alzheimer’s disease – the most common cause of dementia, is different from the cause of frontotemporal dementia. There are some factors we can’t change, such as our genes. There are some things we can do to reduce the chances of developing the condition.

It’s important to make sure that any long-term health problems are managed as well as possible. These could include diabetes, high blood pressure, or mental health problems, such as depression or anxiety.

If you have any of these or think you may be at risk of developing them, it’s important to check in with your GP and take any medications they prescribe.

You can also try to make your brain healthier through positive lifestyle changes, like exercising more, stopping smoking and reducing alcohol intake.

I'm considering taking a dementia supplement

If you are considering purchasing and taking a supplement that claims to prevent or treat dementia or memory issues, ensure you discuss this with your doctor before doing so.

Dr Fiona Carragher, Chief Policy and Research Officer at Alzheimer's Society, explains the importance of trusted sources.

“We are aware of companies marketing supplements online with misleading evidence that they can prevent or even treat dementia.

“We know there is a lot of fear and uncertainty surrounding dementia, and anyone looking to reduce their risk deserves to receive accurate information.

“Research, including our own, has revealed a number of lifestyle changes that can help prevent dementia.

“It’s frustrating that people are being taken away from our evidence-based robust advice and guidance and being pointed instead to misleading claims for financial gain.”

Alternative therapies for dementia

There is so much information available online about alternative therapies for dementia. Some of it is true, but some stretch the truth. Alzheimer's Society ensures all the information we provide is always backed up by evidence and will ensure you have all the facts to make an informed decision.
