Nearly Half of ADHD and Autism Videos on TikTok Contain Misleading Information, Study Finds

A new study reveals that a large portion of social media content about mental health conditions is not accurate. Researchers found that TikTok is the platform most likely to share misleading information about ADHD, autism, and other mental health topics.

The study, published in the Journal of Social Media Research, was conducted by scientists at the University of East Anglia’s Norwich Medical School. They discovered that 52% of the most popular ADHD videos and 41% of top autism videos on TikTok contained information that was either wrong or not backed by current medical evidence.

Researchers looked at content across several platforms, including YouTube, TikTok, Facebook, Instagram, and X (formerly Twitter). They identified TikTok as the biggest source of misleading mental health content. Many of these videos relied on personal stories and simplified traits instead of official diagnostic guidelines or professional advice.

“Our work uncovered misinformation rates on social media as high as 56%. This shows how easily engaging videos can spread widely online, even when the information isn’t always accurate,” said Eleanor Chatburn, a Clinical Psychologist from UEA’s Norwich Medical School and the senior author of the study.

“Social media has become an important place where many young people learn about mental health, but the quality of this information can vary greatly. This means that misleading content can circulate quickly, particularly if there aren’t accessible and reliable sources available,” she added.

Why misleading mental health information spreads easily on social media

Darren O’Reilly, a consultant psychologist and clinical director at AuDHD Psychiatry, said he is not surprised by these findings. He was not involved in the study.

“I’m not surprised that social media, and TikTok in particular, seems prone to misinformation since it rewards fast, emotionally engaging and highly relatable content and not the careful, evidence-based and clinically accurate content,” he told Healthline.

Part of the problem, he noted, is that this type of content can feel very validating, even when it is not accurate.

“TikTok does not reward being right. It rewards being relatable, confident, and easy to share,” he said. “With ADHD and autism in particular, people can recognize one small part of themselves in a video and mistake that recognition for proof. But short-form mental health content tends to flatten complex conditions into a few catchy traits, and that is where misinformation spreads fastest.”

As a result, O’Reilly said he often sees people arriving at his clinic with a strong self-diagnosis based on social media content, when the reality is often much more complicated.

“ADHD and autism are especially vulnerable to oversimplification because their traits overlap with everyday experiences such as stress, burnout, trauma, and anxiety. That makes inaccurate content feel convincing, even when it is clinically incomplete or wrong,” he noted.

How mental health misinformation on social media causes harm

If online content about mental health feels relatable and validating, you might wonder what the harm is. One major issue is that it can cause confusion and lead to misdiagnosis. O’Reilly said that in some cases, people can spend years trying to solve the wrong problem.

“What we often see is a double risk. Some people take on a diagnosis that does not really fit, while others dismiss symptoms that actually need proper attention,” he explained. “When people are self-diagnosing based on short-form content, they are usually matching one or two traits, rather than seeing the full picture. That can lead them down a path that does not actually address what is going on.”

In some cases, O’Reilly said, this can delay people from getting a proper assessment. For others, it can mean a delay in getting the right support.

“A big part of the problem is that online content tends to blur the line between normal human experiences and clinical conditions. Things like distraction, stress, or emotional ups and downs get presented as signs of a disorder, when they may not be,” he explained. “For people who are genuinely neurodivergent, this can delay access to the right support or lead to misunderstanding their own needs. For others, it can mean unnecessary labels, increased anxiety, and trying interventions that do not help.”

Increased mental health awareness needs to be balanced with accuracy

One of the biggest benefits of social media is that it can raise awareness about topics that are not often discussed. Content on platforms like TikTok can start productive conversations and reduce stigma. However, increased awareness around mental health and neurodivergence needs to be balanced with accuracy.

“What is spreading online is not just awareness, it is a simplified, non-clinical version of these conditions. Social media has made neurodivergence visible, but visibility is not the same as understanding,” O’Reilly noted.

“The benefit is that people feel able to explore their difficulties without shame, which increases help-seeking. The risk is that awareness turns into overconfidence, where people move from ‘this resonates’ to ‘this explains everything’ without proper assessment,” he explained.

The challenge is removing the oversimplification around these conditions. “ADHD and Autism are complex developmental conditions, and if they are reduced to a handful of traits, people gain awareness but lose accuracy,” O’Reilly said. “The goal is not to reduce conversation, but to anchor it in evidence, where lived experience is shared but not mistaken for diagnosis.”

Tips to identify mental health misinformation on social media

What practical steps can you take to spot misinformation, and where can you find reliable mental health and neurodivergence support?

“If a video claims, ‘If you do this, you have ADHD or autism,’ it is almost certainly misleading. Real diagnoses are based on patterns, impairment, and history, not one trait,” O’Reilly said. “Good information explains context and limitations, while bad information speaks in absolutes and skips over nuance.”

As a rule of thumb, O’Reilly advised the following:

– Avoid content that reduces a condition to a single behavior or quick fix.

– Look for whether the creator has relevant clinical training or cites credible sources.

– Check if multiple explanations are considered, not just one diagnosis.

– Be cautious of content that feels overly certain or definitive.

– Cross-check with established sources like the National Institute for Health and Care Excellence.

For evidence-based support, O’Reilly advised seeking out regulated professionals such as clinical psychologists, psychiatrists, or specialist ADHD and autism services.

“A proper assessment should involve developmental history, functional impact, and consideration of alternative explanations, not just symptom checklists,” he noted.
