Growing numbers of people are turning to social media platforms — including TikTok, Instagram, YouTube, and Reddit — to learn about mental health conditions and connect with others who share similar experiences.
The conditions being discussed extend well beyond familiar diagnoses like depression, anxiety, and schizophrenia. Conversations increasingly include conditions that fall under the umbrella of “neurodivergence,” such as autism, ADHD, Tourette syndrome, and dyslexia. On TikTok alone, the hashtag #adhd has accumulated more than 50 billion views.
Researchers set out to examine how social media platforms are shaping the way people understand mental health. To do so, they analyzed more than 14 million posts and comments on Reddit. Their analysis found that online discussions are shifting noticeably toward ADHD and autism, and away from anxiety and depression — a finding with significant implications for how people perceive and seek help for mental health challenges.
The Upside and Downside of Online Connection
The rise of mental health content on social media has increased its visibility, with some genuinely positive effects. It has likely reduced the stigma around mental illness and encouraged greater use of mental health services.
There are downsides as well, however. Excessive exposure can trigger or worsen eating disorders, contribute to the spread of behaviors such as tic-like movements, and fuel questionable self-diagnoses. Misinformation is also widespread: one study found that the majority of the most popular TikTok videos about ADHD were misleading. Similar patterns have been documented across other mental health conditions on social platforms.
How the Conversations Are Evolving
The online conversation around mental health has not simply grown in volume — its focus has shifted. Certain conditions are drawing far more attention than before, while others are receding, altering the balance between them.
A Reddit study published last year found that communities centered on ADHD and autism became particularly active between 2012 and 2022, with increasing overlap in both their membership and their content. The discussions concentrated more and more on adult experiences, difficulties accessing diagnostic evaluations, and challenges in personal relationships.
The New Research
A more recent study analyzed over 14 million posts and comments from some of Reddit’s largest mental health communities. The 14 communities examined covered mood disorders, anxiety, trauma, personality disorders, dissociation, and psychosis, along with conditions like autism, ADHD, Tourette syndrome, and dyslexia.
The analysis covered the period from 2015 to 2022, tracking changes in language and community membership, and examining how those shifts reflected a change in which disorders were receiving the most attention.
In 2015, communities focused on depression and anxiety were the most active and most interconnected with others. By 2022, ADHD and autism communities had emerged as the most prominent, fundamentally changing the landscape of online mental health discussion.
While Reddit users are not representative of the general population — they tend to skew younger, male, and more tech-savvy — the study provides valuable insight into how mental health is being discussed online.
Why It Matters
The growing visibility of ADHD and autism on social media is making them increasingly common explanations for mental health struggles. This can help people recognize their difficulties earlier. But it can also lead to misinterpretation, with individuals incorrectly attributing their symptoms to ADHD or autism when a different underlying cause is at play.
These misunderstandings can delay access to appropriate treatment, place additional strain on mental health services, and leave other conditions undiagnosed.
