Neurodiversity is a term used to describe neurological differences in the human brain. It sees the diverse spectrum of neurological difference as a range of natural variations in the human brain rather than as a deficit in individuals. It is an umbrella term that includes both conditions that are life-long and those that can develop throughout life, including acquired illness or brain injury, Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), dyscalculia, dyslexia, dyspraxia, intellectual disability, mental health, and Tourette syndrome. Neurodiversity deliberately rejects the medical model of diversity that frames human differences as disorders that need to be cured in favour of a more social model of diversity as a natural occurrence.
