Myths and Misinformation about Dementia and Alzheimer's Disease

I recently had a conversation with a smart, accomplished lady about the COVID-19 vaccine. She told me she would not be getting the vaccine because she had read online that it contained aluminum, “and aluminum gives you Alzheimer’s Disease.” Now, that is simply not true. It is true that scientists hypothesized a relationship between aluminum and AD several years ago, but the evidence did not support that theory, and at any rate, the type of aluminum salt in a vaccine dose is tiny and has been safely used and studied since the 1930s.

This lady got this misinformation about the COVID-19 vaccine on Facebook. I encouraged her to speak with her doctor about vaccine ingredients and her concerns, but I fear the damage is already done. I doubt she will get the vaccine.

This frustrates and saddens me, but it also got me thinking about other myths and misinformation that are out there about Alzheimer’s Disease and dementia. Let’s discuss a few common myths:

MYTH ONE: Dementia is heredity and cannot be avoided. Genetics are a factor for many types of dementia, but there are many ways to reduce your risk, even if you have a family history of dementia. For example, if you smoke, you can likely reduce your risk by stopping . Type 2 diabetes is a risk factor for both Alzheimer’s Disease and vascular dementia, so a healthy diet and regular exercise may help control your risk.

MYTH TWO: The only symptom of dementia is memory loss. Short term memory loss is common with many types of dementia, but some people with dementia can have a variety of symptoms, such as personality changes, lack of inhibition, depression, and self neglect. It is important to keep your care provider informed about what’s going on with you or your loved one.

MYTH THREE: Memory problems are always a sign of dementia. Humans aren’t that great at memory to begin with (for example, see the research on credibility of eyewitness testimony). So if you notice memory problems, don’t panic. People experience memory problems related to depression and stress. So it is important to talk to your doctor about memory issues.

In sum, please get your information about dementia and COVID-19 from your doctor or care provider, not social media. And read more from the actual experts:
