Would you join a clinical trial advertised on Facebook? The ethics of dementia research content on social media

Some areas of dementia research are relevant to healthy older adults, and social media can help spread the word. What should researchers and the public know about dementia research content on social media to support future brain health?

Dementia risk reduction is highly relevant for healthy adults. Addressing certain lifestyle factors may reduce future cases of dementia (1). Examples include education, performing physical activity, quitting smoking, preventing head injury, and stabilizing blood pressure.

Online exposure to this topic may encourage lifestyle changes but also promote much-needed dementia research participation for risk reduction. Some dementia researchers are turning to social media as a low-cost way to increase community awareness and research participation (2–5).

Appropriateness of social media in brain health research

Health-related content on social media is not without risk. Ethical concerns accompany the use of social media in research (6,7). Common concerns include privacy, confidentiality, informed consent, the spread of misinformation, and the protection of vulnerable groups. 

Understanding how dementia research is typically presented online can inform social media use to improve public involvement. Currently, however, there is no thorough overview of the type of dementia research content users may encounter on social media. 

To inform future ethical guidance of online brain health engagement, we investigated current uses of social media for dementia research.

Dementia research on Facebook vs. Twitter

We reviewed a sample of public dementia research posts on Facebook and Twitter (8). Our analysis included understanding the types of users posting about dementia research and the topics discussed. 

Facebook users were mainly advocacy and health organizations rather than individuals. In contrast, Twitter users largely had academic or research backgrounds. This difference in user groups may explain the greater amount of academic content on Twitter, such as peer-reviewed research articles. Most research articles were open access and available to the public but may not be accessible for a wide range of literacy levels.

For both platforms, prevention and risk reduction were main areas of focus in dementia research. Posts with these topics appeared the most frequently and received a lot of attention in the form of likes, shares, and comments.

Other popular topics included dementia treatment and research related to the detection of dementia. Treatment posts primarily discussed the approval of aducanumab1 by the Food and Drug Administration (FDA), leading to much online debate. This may explain why, at the time, non-academic users had more interactions on dementia treatment tweets. The purpose behind most posts was to share dementia research information and knowledge.

On risk, responsibility, and stigma

The posts in our social media data emphasized individual prevention efforts, such as diet and exercise. However, topics also included social and environmental barriers that interfere with dementia risk reduction, care, treatment delivery, and other research areas. 

As stated in one Facebook post, “[the] social determinants of health can significantly impact brain health disparities & the ability to access care.”

Barriers are unequally distributed across communities that vary by race, ethnicity, sex and gender, socioeconomic background, disability, and other aspects of identity.

Dementia researchers on social media should avoid using language that elicits stigma or equates brain health with personal responsibility (9). Society-wide initiatives that overcome barriers can potentially impact future population health on a broader scale positively and more effectively.

Practical social media guidance is needed for dementia research

A better understanding of the dementia research space on social media can inform future ethical guidelines. Dementia research engagement should incorporate the community’s values and perspectives on using social media for risk reduction.


1 The FDA approved aducanumab as a treatment for Alzheimer’s disease in June 2021. The decision was met with much controversy and ethical discussion. More information can be found here.
