Study Reveals High Levels of Mental Health Misinformation on TikTok, Especially About ADHD and Autism

Researchers from the University of East Anglia (UEA) have discovered that social media platforms, particularly TikTok, are becoming breeding grounds for mental health misinformation, with content about ADHD and autism especially prone to inaccuracies.

The study found that young users increasingly turn to social media platforms to self-diagnose or understand symptoms they may be experiencing, creating a potentially dangerous situation where medical misinformation can flourish unchecked.

Dr. Eleanor Chatburn from UEA’s Norwich Medical School, one of the study’s lead researchers, explained the concerning trend: “While this questioning can be a helpful starting point, it’s important these questions lead to proper clinical assessment with a professional.”

The consequences of such misinformation extend beyond simple confusion. “As well as leading to misunderstanding of serious conditions and pathologising ordinary behaviour, misinformation can also lead to delayed diagnosis for people that actually do need help,” Dr. Chatburn warned.

This problem is particularly acute for neurodevelopmental conditions. The research team discovered that posts discussing ADHD (Attention Deficit Hyperactivity Disorder) and autism contained significantly more inaccuracies than content about other mental health topics. This pattern raises concerns as both conditions require careful clinical assessment rather than self-diagnosis based on potentially misleading social media content.

The researchers pointed to TikTok’s algorithm as a potential amplifier of the problem. The platform’s recommendation system, designed to maximize engagement, may inadvertently push misleading content to vulnerable users seeking information. The study authors called for “strengthened content moderation” to address these issues.

When approached for comment, TikTok strongly contested the findings. A spokesperson for the platform described it as a “flawed study” that relied on “outdated research about multiple platforms.” The company defended its practices, stating, “The facts are that we remove harmful health misinformation and provide access to reliable information from the World Health Organization, so that our community can express themselves about what matters to them and find support.”

However, advocacy groups have backed the study’s conclusions. Judith Brown, head of evidence and research at the National Autistic Society, highlighted “how rapidly” misinformation can spread on social media platforms. She echoed the researchers’ call for improved safeguards, stating that “social media companies should think about how to improve their platforms to prevent the spread of misinformation.”

The study comes amid growing concern about social media’s influence on mental health diagnosis and treatment. In recent years, there has been a notable increase in people seeking assessments for conditions like ADHD and autism after viewing content on platforms like TikTok. While raising awareness can be beneficial, experts worry that simplified or inaccurate portrayals may lead to misdiagnosis or trivialize serious conditions.

Mental health professionals have observed this phenomenon firsthand, with many reporting an uptick in patients arriving at appointments with preconceived notions based on social media content rather than medical literature.

The challenge for platforms like TikTok balances allowing users to share personal experiences—which can reduce stigma and create community—while preventing the spread of potentially harmful misinformation. Content moderation at this scale presents significant technological and ethical challenges.

As social media continues to evolve as a source of health information, this research highlights the urgent need for platforms, health organizations, and users to work together to ensure accurate information prevails in digital spaces where millions seek answers about their mental health.
