The term neurodiversity was first used in the late 1990s by members of the Autism community to reframe conversation away from the language of "disorder" or "deficit" to a more inclusive and respectful angle. Neurodiversity suggests that neurological differences are natural variations of the human brain, much like biodiversity seen in nature.
The term emphasises that differences are not defects that need to be fixed, but rather, they are part of human diversity. Over time, the neurodiversity movement has grown to advocate for societal acceptance and equal opportunities, promoting the idea that every person's neurology should be respected and valued.
