You are scrolling through TikTok during your lunch break when a video about attention-deficit/hyperactivity disorder (ADHD) catches your attention. The creator describes symptoms such as difficulty concentrating, forgetfulness and restlessness. You recognise some of these behaviours in yourself and begin to wonder, “Could I have ADHD?”
You watch another video, then another. The more you watch, the more familiar the descriptions seem. Soon, a question turns into a conclusion: “I have ADHD.”
Social media can help people understand mental health and recognise experiences they may previously have struggled to explain. But identifying with a video does not necessarily mean you have the condition being discussed.
Who should you trust?
Mental health content has become increasingly popular online, with videos covering conditions ranging from anxiety and depression to ADHD and personality disorders.
Some creators are qualified mental health professionals who use social media to educate the public. Others share personal experiences or offer advice without clinical training.
Personal stories can help people feel understood, but they may not capture the full picture of a condition. Some videos oversimplify symptoms, leave out important details or present information that is not supported by scientific evidence.
A study published in The Canadian Journal of Psychiatry found that 52 per cent of the 100 most popular ADHD videos on TikTok in 2021 were misleading. Another 27 per cent featured personal experiences, while 21 per cent provided useful information.
A creator’s qualifications matter, but so does the evidence behind their claims and whether they are speaking within their area of expertise.
Social media platforms also reward content that attracts attention. Dramatic claims, relatable symptoms and quick answers can generate views, sometimes at the expense of accuracy. Explaining a complex mental health condition in a short video can leave out the context needed to understand it properly.
When a label changes how you see yourself
Repeatedly watching mental health content can influence how people interpret their everyday experiences.
Once someone suspects they have a particular condition, they may begin paying closer attention to experiences that support that belief while overlooking information that contradicts it.
For example, someone who identifies with a video about depression may begin interpreting changes in mood, sleep or motivation through that lens. These experiences may deserve attention, but they do not establish a diagnosis on their own.
This relates to confirmation bias, the tendency to notice and favour information that supports an existing belief.
Social media algorithms can reinforce this process by recommending similar videos based on what a person watches, likes or shares. As a result, someone who begins by exploring a possible condition may find themselves surrounded by content that appears to confirm their suspicions.
A 2025 study involving young adults seeking treatment for mood and anxiety disorders found that many participants who believed they had a diagnosis that had not been given by a professional reported that social media had contributed to that belief.
The findings highlight how online information can shape people’s understanding of their mental health, although they do not mean that every person who suspects a condition has been misled.
The good side of mental health content
Despite these concerns, social media can play an important role in mental health education.
For many people, online content provides their first introduction to conditions they know little about. Qualified professionals use these platforms to explain symptoms, challenge misconceptions and encourage people to seek help.
Social media can also help people who have limited access to mental health services. It can give them language to describe their experiences, introduce them to available support and reassure them that they are not alone.
Personal stories from people living with mental health conditions can reduce stigma and encourage others to speak openly about their struggles.
The problem arises when awareness turns into self-diagnosis.
Many mental health symptoms overlap. Difficulty concentrating, for instance, may be associated with ADHD, but it can also occur with sleep deprivation, stress, anxiety or other health concerns. Low mood and changes in sleep can have several explanations, too.
A short video cannot establish how long symptoms have lasted, how severely they affect someone’s life or whether another condition might explain them.
Recognising a possible problem is a useful first step. Understanding what is happening requires a more complete assessment.
How to separate facts from misinformation
The Centre for Clinical Interventions (CCI) recommends taking care when using social media for health information.
Start by checking who created the content. Are they qualified to discuss the subject? Do they refer to credible evidence, or do they rely on personal opinions and sweeping claims?
Be cautious of promises of quick fixes, advice presented as suitable for everyone and recommendations that contradict professional guidance without credible evidence.
Most importantly, seek help from a qualified mental health professional if symptoms are persistent, distressing or affecting daily life.
A professional assessment considers more than a checklist of behaviours. It explores a person’s history, symptoms, circumstances and how these experiences affect their functioning.
The next time a TikTok video makes you question your mental health, pause before accepting the label. Ask yourself whether the information is credible and whether it provides enough context to explain what you are experiencing.
You do not have to dismiss everything you learn online. A video might help you recognise a concern you had not previously understood or give you the confidence to seek support.
But let social media raise the questions, not provide the final answers.
Dr TikTok may help you start the conversation. A qualified professional can help you understand the full picture.
