Central to neurodiversity is the idea that naturally occurring variations in the human brain should be seen as differences rather than deficits. Some people consider neurodiversity to be related to the concept of biodiversity — a term you will mostly see being used for the purpose of advocating for the conservation of species.
People think, learn, behave, and experience the world around them in many different ways. Some of this diversity is due to neurological differences. Neurodiversity refers to those variations in neurocognitive functioning.
