A growing number of social media users are self-diagnosing with autism after consuming TikTok content about the neurodevelopmental condition, prompting mental health experts to issue warnings about the limitations and potential dangers of online self-assessment.
Dr. Emily Newton, a licensed clinical psychologist and vice president of diagnostic services at Axis for Autism, emphasized that while social media platforms can serve valuable educational purposes, they cannot replace professional clinical evaluation. "While social media can be a strong tool for increasing awareness and connection, it is not a diagnostic tool," Newton stated. "We need to be mindful of the complexity involved in understanding an individual's traits and behaviors, including the importance of clinical context."
Diagnostic Rates Continue to Rise
Autism diagnoses have increased dramatically over the past two decades. According to recent data, diagnoses rose from 1 in 150 children in 2000 to 1 in 31 by 2022. Adults between the ages of 26 and 34 experienced a particularly striking 450 percent increase in diagnoses between 2011 and 2022.
Scientists attribute this surge to multiple factors, including expanded diagnostic criteria, improved screening tools, and heightened public awareness. Social media has likely played a role in this awareness, with the hashtag #actuallyautistic generating more than 900,000 posts on TikTok alone.
Pandemic Isolation Accelerated Online Self-Diagnosis
The trend toward self-diagnosis gained significant momentum during the COVID-19 pandemic, when social isolation drove teenagers and young adults to seek identity and community online. This period saw increases in self-diagnoses not only for autism, but also for ADHD, obsessive-compulsive disorder, dissociative identity disorder, and Tourette syndrome.
Newton noted that the phenomenon extends beyond young people. Adults across age groups have reported experiencing recognition moments while viewing neurodivergent content online. The psychologist observed that social media has democratized representation of autism, showing that the condition affects individuals across all genders, sexual orientations, races, and professions.
Common Traits Often Misattributed to Autism
Autism is classified as a spectrum disorder because it encompasses a wide range of symptoms that vary significantly in severity. The condition frequently overlaps with ADHD and anxiety, with over half of individuals with autism also receiving an ADHD diagnosis—a combination known as AuDHD.
Newton explained that traits such as difficulty with attention, social interactions, friendships, and sensory sensitivities appear across autism, ADHD, and anxiety. This overlap makes professional evaluation by clinicians experienced in assessing all three conditions essential for accurate diagnosis.
Many individuals possess sensory sensitivities or engage in repetitive movements without having autism. "For example, so many people strongly dislike microfiber or repetitively shake their legs when they are nervous or happy—these alone do not mean a person has autism," Newton said. "We cannot diagnose autism based on a single sensory preference or repetitive behavior; these traits must be understood within the broader clinical context."
Proper Evaluation Requires Professional Assessment
Newton described the diagnostic process as examining a constellation rather than a single star. Accurate diagnosis requires understanding developmental history, current behavior, and input from individuals who know the person well.
A comprehensive adult evaluation should include a thorough clinical interview assessing both childhood and adult experiences, completion of autism-specific measures and rating forms by the individual and those familiar with them, and review of relevant records such as previous diagnostic evaluations or childhood documentation.
For individuals questioning whether they might have autism, Newton recommended beginning with a conversation with a primary care physician or mental health professional. Credible online screening tools, including the RAADS-R and the Autism-Spectrum Quotient, can help individuals determine whether pursuing a formal evaluation would be beneficial, though these tools cannot provide diagnoses.
"There are many great clinicians, both nationally and locally, who want to support adults looking to go through an autism evaluation," Newton concluded. "It is never too late to learn more about yourself."
