Experts Warn Against Overuse of 'Neurodivergent' Label
A review of studies suggests the term is being applied too broadly, potentially overshadowing genuine diagnoses and impacting access to resources.
The term 'neurodivergent' is increasingly being used as a catch-all label, potentially undermining individuals with formal diagnoses of conditions like ADHD and autism, according to British researchers. Experts warn that this broad application risks diluting the significance of these diagnoses and may hinder access to essential resources for those with confirmed medical conditions.
In a review analyzing over 134 studies involving approximately 150,000 participants, primarily from the UK and US, psychiatric experts from the University of Southampton identified concerns regarding the widespread use of the terms 'neurodivergent' and 'neurodiverse.' The researchers found that these terms were frequently applied to individuals without a formal diagnosis, or in studies where no specific diagnosis was listed.
While the review identified conditions such as autism, ADHD, dyslexia, and dyspraxia as commonly associated with the term 'neurodivergent,' it also noted instances where the label was applied to individuals experiencing anxiety, depression, post-traumatic stress disorder, or even those who had suffered a stroke or brain injury. The study, published in JAMA Psychiatry, indicated that a third of the analyzed studies relied on self-identification rather than clinical assessment.
The authors of the review, writing in The Conversation, argue that the broad use of 'neurodivergent' is "unfair" and may obscure the distinct challenges faced by individuals with specific, diagnosed conditions. They highlight that the day-to-day experiences of those with conditions like ADHD and autism can differ significantly from those without a diagnosis.
The review also pointed out a common confusion between the terms 'neurodivergent' and 'neurodiverse.' 'Neurodivergent' describes behavior that deviates from societal norms and is associated with diagnosed conditions such as autism, ADHD, dyslexia, dyscalculia, Tourette's syndrome, and dysgraphia. In contrast, 'neurodiversity' refers to the broader concept that every individual's brain is wired differently. The conflation of these terms can lead to misunderstandings about specific difficulties experienced by individuals.
Conditions like autism and ADHD, while often linked, are distinct disorders. Autism impacts communication, social interaction, and sensory processing, while ADHD affects concentration, activity levels, and impulse control. Each condition has unique clinical features and diagnostic criteria.
The findings emerge as diagnoses for ADHD in England have reached record highs, increasing twentyfold since the turn of the century. Autism diagnoses have also seen a substantial rise, increasing by 787 percent in the UK between 1998 and 2018. This surge has led to increased scrutiny and concerns about over-diagnosing and the medicalization of typical behaviors.
In light of these concerns, a government review into ADHD diagnoses is expected to recommend that healthcare professionals prioritize patients with severe issues related to the condition. While individuals with milder symptoms may still receive support, their access to NHS services could be affected, with approximately 800,000 people currently awaiting assessment for the disorder.
