• A new study has found that a significant amount of social media content about mental health is inaccurate.
• Researchers identified TikTok as the platform most associated with misleading mental health information

• Experts warn that this rise in misinformation may contribute to confusion, misdiagnosis, and delayed support

A new study, published in the Journal of Social Media Research, has found that a significant proportion of social media content about mental health and neurodevelopmental conditions may be misleading.

Researchers at the University of East Anglia’s Norwich Medical School reported that 52% of top-performing ADHD videos and 41% of autism-related videos on TikTok contained information that was inaccurate or not supported by current clinical evidence.

They found that social media platforms, including YouTube, TikTok, Facebook, Instagram, and X (formerly Twitter), are awash with misleading or unsubstantiated mental health content, and identified TikTok as the worst offender.

The study also found that videos were often based on personal anecdotes and simplified traits, rather than diagnostic criteria or professional guidance.

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

“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.”

Darren O’Reilly, DPsych, CPsychol, HCPC, consultant psychologist and clinical director at AuDHD Psychiatry, said he isn’t surprised by these findings.

“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.

O’Reilly was not involved in the study.

Part of the problem, he noted, is that this kind of content can feel hugely validating, even if it’s not accurate.

“TikTok does not reward being right. It rewards being relatable, confident, and easy to share,” he pointed out.

“With ADHD and autism in particular, people can recognise 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 in the clinic with a strong self-diagnosis based on social media content, when the reality is often much more complex.

“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.

When online content about mental health and neurodivergence can feel relatable and validating, you might ask, what’s the harm?

One of the biggest issues is that it can lead to confusion and 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 in 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.”

Perhaps one of the biggest benefits of social media is that it can raise awareness of topics that aren’t often discussed.

Content on platforms like TikTok can spark 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 the 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.”

So, what practical steps can you take to identify misinformation, and more importantly, where can you find reliable and accurate 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 said you should avoid content that reduces a condition to a single behaviour or quick fix, look for whether the creator has relevant clinical training or cites credible sources, and check if multiple explanations are considered, not just one diagnosis.

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.
