What do “neurodiverse” and “neurodivergent” mean?
Terms such as “neurodiverse” and “neurodivergent” were introduced in the 1990s by autistic sociologist Judy Singer as an alternative to deficit-based language, such as “disorder.” Singer highlighted notable strengths of many individuals in the autistic population that include abilities to focus, recognize patterns, and remember factual information. A “neurodivergent” person refers to a person on the autism spectrum or, more generally, to someone whose brain processes information in a way that is not typical of most individuals. These people may have learning disabilities, attention deficit and anxiety disorders, obsessive-compulsive disorder, and Tourette’s syndrome. Through a neurodiversity lens, such conditions reflect different ways of being that are all normal human experiences.
Although “neurodiversity” is usually used to describe a group of neurodivergent individuals, it also refers to all of humankind because everyone has a unique way of processing information.
