The term "neurodivergent" is becoming more common in everyday language, social media, and scientific discussions. It refers to people whose brains function in ways that differ from what is considered typical. It is often used to describe individuals with conditions like autism or ADHD. However, experts have not yet reached a clear agreement on exactly how to define the term or which medical conditions it should include. A review of 134 scientific studies involving more than 151,000 participants found almost 20 different medical conditions associated with neurodivergence and neurodiversity. Autism and ADHD were the most commonly mentioned, followed by dyslexia and dyspraxia. Other conditions, such as anxiety, depression, post-traumatic stress disorder, and even neurological injuries like stroke or traumatic brain injury, also appeared in the research. Some studies used the terms "neurodivergent" and "neurodiverse" without clearly linking them to specific diagnoses, while a third of the studies relied on people self-identifying as neurodivergent rather than using formal medical evaluations. In some cases, researchers confused the two terms, despite their different meanings. "Neurodiversity" refers to the natural variation in how people think, learn, and process information. It is a concept that describes a group, such as a community or society, rather than an individual. It is accurate to say "our society is neurodiverse." "Neurodivergent," in contrast, refers to an individual whose brain functions differently from the typical. However, there is currently no widely accepted way to define or measure this difference. Doctors can use well-established guidelines to diagnose specific conditions like ADHD or autism, but there is no single test to determine whether someone is "neurodivergent" or "neurotypical." The terms "neurodiverse" and "neurodivergent" came from the neurodiversity movement, which seeks to improve rights and inclusion for people with neurodevelopmental conditions, especially autistic individuals. These terms are now used in schools, workplaces, and the media, often as alternatives to naming specific conditions. Conditions like autism and ADHD are grouped together in the Diagnostic and Statistical Manual of Mental Disorders (DSM) because they often share overlapping traits. However, each condition has its own unique characteristics and diagnostic criteria. Using "neurodivergent" as a general term can blur these distinctions, potentially causing confusion in research, healthcare, and education. Terms like "neurodivergent" can also create challenges for the public. Policies based on these terms may not effectively address the specific needs of individuals with certain conditions. Additionally, the idea that "everyone is neurodiverse" can lead to misunderstandings, such as implying that people without a diagnosis are "a bit autistic" or "a bit ADHD," which can be unfair to those with established conditions. While the terms "neurodiversity" and "neurodivergence" can be helpful in describing shared experiences and identities, clear and recognized medical diagnoses are generally more useful in clinical settings, healthcare, and education.
