Welcome. Before we go deep into any single condition, profile, or workplace strategy, we need a shared vocabulary. This first lesson takes about ten minutes and sets the orientation for everything that follows. You'll leave with a working definition of neurodiversity, a clear sense of why the language we use matters, and one concrete personal goal for the rest of the path.
Neurodiversity is the simple, scientifically grounded observation that human brains vary — in attention, sensory processing, memory, social cognition, and learning — and that this variation is a normal feature of our species, not a defect to be eliminated. The word was coined in the late 1990s by sociologist Judy Singer to name what autistic, ADHD, dyslexic, and other communities had long described from the inside. Neurodiversity is to brains what biodiversity is to ecosystems: a range, not a hierarchy.
These three words get mixed up constantly. Using them precisely changes the conversation.
The medical-deficit model treats neurodivergence as a disorder to be corrected. The strengths-and-supports model — sometimes called the social model of disability — treats neurodivergence as a real difference that produces real strengths AND real challenges, with environmental design doing most of the work. This course operates entirely in the second model. We name strengths honestly, name challenges honestly, and then ask: what would have to change in the environment for this person to thrive?
Most neurodivergent adults prefer identity-first language ('autistic person', 'ADHDer', 'AuDHDer') because their neurology is part of who they are, not a costume they're wearing. Person-first language ('person with autism') is also valid, especially in clinical contexts. The respectful default is to ask. The disrespectful default is to insist someone else's language is wrong.
Maya, an engineering manager, notices her team uses 'high-functioning' and 'low-functioning' in 1:1s about a new hire. She replaces those terms with descriptions of the environment ('our open-plan floor is hard for him; he does his best work from home Tuesdays and Thursdays'). Within a quarter the same colleagues are sending her better-framed requests for accommodations.
Takeaway: Language sets what becomes possible to ask for. Leaders shift culture by modeling precise vocabulary in low-stakes moments.

Open a note on your phone or a paper journal. Write the sentence: 'By the end of this learning path, I want to be able to ___.' Keep it specific. 'Support my neurodivergent teenager during homework' is better than 'understand neurodiversity.' Return to it after Lesson 10.

I'm a learner working through Lesson 1 of the Understanding Neurodiversity Learning Path. Please quiz me: give me three short scenarios and ask which of 'neurodiversity', 'neurodivergent', or 'neurotypical' fits each. Correct me gently if I miss any and explain why.
Open in CompanionI'm a learner. Take this sentence and rewrite it in strengths-and-supports framing instead of medical-deficit framing, then explain the change in one line: 'He suffers from severe autism and can't function in normal classrooms.'
Open in CompanionI'm a learner starting this Learning Path. Ask me three short questions, then help me write one specific sentence I can use as my learning intention for the next 9 lessons.
