Understanding neurodiversity in childhood
"Neurodiversity" is everywhere, often as a polite synonym for autism or ADHD. It is not one. The word describes something broader, and above all, it says nothing about what any particular child needs. Here is what it covers, where it comes from, and where what it lets you conclude stops.
Key points
- Neurodiversity refers to the diversity of human brains and minds: the variations in neurocognitive functioning within our species.
- "Neurodivergent" describes functioning that differs from socially perceived norms; "neurotypical" describes the majority.
- It is not a diagnosis, and nobody can be "diagnosed as neurodivergent".
- The concept emerged around the autism rights movement in the late 1990s.
- Recognizing a variation says NOTHING about what support a person needs: those are two separate questions.
The words, precisely
- Neurodiversity
- Neurological diversity: the variations in cognitive functioning within the human species. The word describes a fact about a population, not a characteristic of an individual.
- Neurodivergent
- Said of a person whose functioning differs from socially perceived norms. It is a position relative to a norm, not a clinical category.
- Neurotypical
- Said of the majority, whose functioning matches those perceived norms. The word exists only by contrast.
- The neurodiversity paradigm
- The framework that treats such divergences as natural variations and calls for support tailored to individual needs, rather than alignment with a norm.
Where the word comes from, and a useful correction
The concept took shape around the autism rights movement in the late 1990s. It is often credited to a single author and a single year.
Recent work corrects that account: archival findings show the phrase "neurological diversity" was in use earlier, and that both the concept and the theory around it were developed COLLECTIVELY by neurodivergent people.
That correction is not a footnote. It is a reminder that this vocabulary came from the people concerned, rather than being placed on them from outside.
What the word does not let you conclude
Saying a child is neurodivergent does not say what they experience, what it costs them, or what would help. Two children described that way can have entirely different needs.
The framework does not replace an assessment either. It removes no step, and it does not stand against naming difficulties and taking them seriously: recognizing a variation and recognizing a need for support are compatible.
What the word does make visible is real: part of a child's difficulty comes from the gap between how they function and an environment designed for someone else. That gap is often the part that can be narrowed.
What it changes in practice
-
Describe functioning rather than categories: "he needs to know in advance what is going to happen" carries further than any label.
-
Look at what the environment is asking for, before looking at what the child cannot do.
-
Note the settings where things go well: they describe the environment that works.
-
Use the vocabulary the child and the family use for themselves.
-
If an assessment is being considered, that does not contradict this framework.
