More than half of the top-performing TikTok videos about ADHD contain inaccurate or clinically unsupported information, according to a new study published in the Journal of Social Media Research.
Researchers at the University of East Anglia's Norwich Medical School analyzed mental health content across major platforms including YouTube, Facebook, Instagram, X, and TikTok. They found that 52% of leading ADHD videos and 41% of autism-related videos on TikTok included information that did not align with current clinical evidence. Across all platforms studied, misinformation rates reached as high as 56%.
TikTok ranked as the worst offender among the platforms examined. The researchers found that much of the content relied on personal anecdotes and simplified lists of traits rather than diagnostic criteria or guidance from mental health professionals.
"Social media has become an important place where many young people learn about mental health, but the quality of this information can vary greatly," said Eleanor Chatburn, a clinical psychologist at Norwich Medical School and the study's senior author. "This means that misleading content can circulate quickly, particularly if there aren't accessible and reliable sources available."
The structural incentives of short-form video are a large part of the problem, according to Darren O'Reilly, a consultant psychologist and clinical director at AuDHD Psychiatry. "TikTok does not reward being right. It rewards being relatable, confident, and easy to share," he told Healthline. O'Reilly was not involved in the research.
The consequences show up in clinical settings. O'Reilly said he regularly sees patients arrive with a firm self-diagnosis built almost entirely on social media content. "With ADHD and autism in particular, people can recognise one small part of themselves in a video and mistake that recognition for proof," he said. "Short-form mental health content tends to flatten complex conditions into a few catchy traits, and that is where misinformation spreads fastest."
That dynamic can cut two ways. For some people, stumbling across a video may be the first time they consider that their struggles have a name, which can eventually lead them toward a real evaluation. But for others, a confident self-diagnosis built on inaccurate content can delay professional assessment, lead to confusion, or create resistance when a clinician offers a different picture.
Chatburn noted that the speed at which engaging videos spread online outpaces any correction mechanism the platforms currently have. The study's findings put pressure on both social media companies and health communicators to find more effective ways to surface accurate, evidence-based content in spaces where young people are already looking for answers.
