A substantial proportion of TikTok posts about ADHD and autism are misleading - according to a new study from the University of East Anglia. Researchers investigated the accuracy of mental health and neurodivergence information across social media platforms including YouTube, TikTok, Facebook, Instagram and X (formerly Twitter). They found that these platforms are awash with misleading or unsubstantiated mental health content - and that TikTok is the worst offender. The study also reveals that posts about neurodivergence such as autism and ADHD contained higher levels of misinformation than many other mental health topics.
