Neurodiversity Glossary & Definitions
Browse clear explanations of words and phrases used across neurodiversity, neurodivergence, autism, ADHD, AuDHD, sensory processing, communication, executive function, learning, identity, accessibility, support and everyday life. This glossary is designed as a starting point for understanding language — not as a rulebook for how every person must describe themselves.
Gentle notice
Some definitions touch burnout, meltdown, shutdown, anxiety, exclusion or other experiences that can feel personal. You can hide sensitive terms at any time. Take the page at your own pace and use only what is useful to you.
Language, identity & preference
Some people prefer identity-first language such as “autistic person”; others prefer person-first language or different terminology. Community language, professional language and preferred wording also change over time. Respectful language begins with listening to individual preference.
Clinical, educational and legal meanings can differ
Terms can have specific meanings in diagnostic criteria, education systems, disability law or services. Those meanings may vary between New Zealand and other countries. These are educational summaries rather than personalised medical or legal advice.

G
Giftedness
High ability or advanced performance in one or more areas; giftedness can coexist with disability or neurodivergence.

Key neurodiversity categories
Core concepts
Neurodiversity, neurodivergence, neurodivergent identity and the language used to describe neurological variation.
Autism, ADHD & AuDHD
Profiles, diagnoses, overlapping experiences, attention, regulation, masking and everyday life.
Sensory & regulation
Interoception, proprioception, sensory seeking, overload, stimming, regulation and sensory access.
Executive function
Planning, task initiation, working memory, time blindness, switching and organisational support.
Learning & education
Dyslexia, dyscalculia, dyspraxia/DCD, giftedness, learning differences and classroom access.
Identity, access & belonging
Language preference, inclusion, accommodations, accessibility, lived experience and community participation.

Language changes as communities and understanding evolve
Individual preference matters
There is no single preferred label for every neurodivergent person. Ask rather than assume when referring to an individual.
Community and clinical language differ
Words such as AuDHD, time blindness and masking may be common in communities even when they are not formal diagnostic labels.
Country context matters
Education, disability and diagnostic terminology can differ significantly between New Zealand and other countries.
Older resources may use older wording
Historical material can reflect the language of its time. That does not always mean the same wording is preferred today.
Debated terms need context
Some language, including PDA-related terminology, may be accepted in some settings and contested or unsupported in others.
Lived experience adds meaning
A definition can explain a word, but it cannot replace listening to how a person experiences their own mind, body and support needs.


Connected concepts
Neurodiversity ↔ Neurodivergence
Neurodiversity describes variation across people; neurodivergence is commonly used for neurological patterns that differ from dominant expectations.
Masking ↔ Unmasking
Masking describes hiding or altering traits; unmasking describes reducing that effort in safer and more accepting contexts.
Overload ↔ Regulation
Overload reflects demands exceeding current processing capacity; regulation describes processes that help the nervous system return toward a manageable state.
Accommodation ↔ Accessibility
An accommodation changes something for an individual; accessibility and inclusive design aim to reduce barriers more broadly.
Strengths ↔ Support needs
Abilities and support needs are not opposites. A person can have significant strengths and still need meaningful support.
Identity ↔ Diagnosis
A diagnosis can be useful for understanding and access, while identity describes the wider meaning a person gives to their experiences and sense of self.

Clear words can support better understanding
Terminology changes, people have different preferences, and no short definition can describe a whole person. This glossary is here to make language easier to understand while keeping room for individual experience, context and choice.
