A good definition of the term comes from the WebMD website, which says that “Neurodiversity isn’t the same thing as disability. Certain developmental disorders are normal variations in the brain. And people who have these features also have certain strengths.”
Wikipedia goes on to explain that by using the term neurodiversity rather than disability, you are “acknowledging that neurodiversity does not require a cure, giving non-neurotypical individuals more control over their treatment, including the type, timing, and whether there should be treatment at all.”
