Professor Dame Uta Frith, a pioneering researcher in the field of autism, has expressed concern that the condition is being overdiagnosed, attributing the surge in diagnoses to an overly broad definition and the impact of social media. In a paper published in the journal Psychological Medicine, Frith argues that the criteria for diagnosing autism have become too vague and are influenced by "misleading" ideas popularized online.
Frith, affiliated with the Institute of Cognitive Neuroscience at University College London, noted that autism was initially identified in the 1940s as referring to a small group of children with severe difficulties in social interaction, communication, and behavior. Over time, she explained, the definition has expanded to encompass individuals with milder traits and without language or learning impairments. "Today, anyone of any age or intelligence level can be diagnosed with autism if they meet certain criteria," Frith wrote.
She suggested that the term has become a "catch-all diagnosis" for various psychological issues that may require different forms of treatment. Recent figures from the UK indicate a significant rise in autism diagnoses, with over 200,000 individuals now awaiting specialist assessment, a threefold increase since 2021. Studies over the past two decades show a surge of more than 700 percent in diagnoses.
Experts have previously pointed to increased awareness of autism signs, partly driven by social media content, as a factor in this rise. Autism is described as a lifelong disability affecting how individuals interact with the world, commonly causing challenges in communication, socialization, and learning. Some individuals with autism also experience learning disabilities and are at a higher risk for conditions such as epilepsy, eating disorders, and anxiety.
While charities now often refer to autism as a form of "neurodivergence" rather than a developmental disorder to reduce stigma, Frith posits that this shift also creates tension. "If autism is not a disorder, why use a medical diagnosis?" she questioned.
Frith specifically criticized social media for "spreading simplified ideas" about autism, stating that the diagnosis has become "part of popular culture." She noted that while online platforms, films, and communities facilitate shared experiences, they also disseminate simplified or misleading information. She called for medical professionals to identify other underlying psychological problems and provide appropriate treatment, distinguishing between interventions for conditions like anxiety and depression and those specific to autism, such as therapies for burnout and sensory overload. Frith believes such a reorientation could lead to more accurate support and address the "tragic neglect of those with the most severe impairments."
Approximately three percent of children in the UK are estimated to have autism. Early indicators can include avoiding eye contact, not responding to their name, repetitive movements, and reduced engagement in play, according to the NHS.
Mel Merritt, head of policy and influencing at the National Autistic Society, responded to Frith's paper by emphasizing the understanding of autism as a spectrum with unique characteristics for each individual. Merritt stated that terms like "milder traits" might not accurately reflect the daily challenges faced by many autistic individuals and that it is unhelpful to create a false dichotomy between autistic people. The focus, Merritt argued, should be on improving access to quality assessments and tailored support, and addressing the "chronic inequalities" faced by autistic people.
