The Neurodiversity Glossary

The Neurodiversity Glossary

70+ terms defined with clarity, care, and lived experience

If you’re new to Autistic or ADHD spaces, it can feel like everyone else got a dictionary you somehow missed. The language is rich, evolving, and sometimes disorienting, especially when you’re already carrying a lifetime of “I must have missed a social rule again.”

This glossary is designed as a gentle on-ramp. We translate terms you’ll encounter in neurodivergent communities into clear, practical language, grounding each one in both clinical insight and lived experience. The goal is to offer words that help you name what’s happening in your mind, body, and relationships, without pathologizing your way of being.

What’s Inside
A beautifully illustrated, 113-page digital PDF covering 65+ terms organized A to Z, including:

• Core concepts: neurodivergence, neurotypical, neurodiversity, identity-first language
• Autism and ADHD foundations: AuDHD, masking, camouflaging, special interests, monotropism, executive functioning, hyperfocus
• Nervous system and regulation: burnout, window of tolerance, sensory meltdown, sensory shutdown, dissociation, dorsal vagal, hypoarousal, hyperarousal
• Emotional experience: alexithymia, rejection sensitive dysphoria, emotional dysregulation, emotional processing
• Social and relational: double empathy problem, cross-neurotype communication, demand avoidance, PDA
• Identity and advocacy: ableism, internalized ableism, intersectionality, unmasking, self-advocacy, neuroqueer, lost generation
• Practical tools and frameworks: pacing systems, body doubling, weighted blankets, proprioception, interoception.

Each entry includes a clear definition, and context that connects the term to real, recognizable experience.
