The Neurodivergent Glossary

This is a thorough but far from comprehensive list. You'll find there's a lot of overlap of symptoms between terms found here, as the architecture of our brains is nothing if not complicated and subtle!
Many terms here will also have some overlap with neurotypical brains however their presentation or severity will differ dramatically.
Glossary of Neurodivergent Terms
