Everybody's neurodivergent now, and everybody's selling: labels and language on TikTok

Scroll long enough and the feed will diagnose you. "Signs you might be AuDHD." "Things you do that are actually ADHD." A sixty-second clip, a list of traits that sound familiar, a comment section full of people saying this is literally me. It is giving revelation, and it is worth slowing down to ask what is actually happening, because two big things are happening at once: a wave of self-labeling, and a language machine that makes labels spread like sounds.

Thread one: why everybody is neurodivergent now

Start with what researchers actually found. In a 2025 study published in PLOS One, Vasileia Karasavva and colleagues at the University of British Columbia took the 100 most popular TikTok videos under the hashtag #ADHD, which together had more than half a billion views, and had two clinical psychologists check every claim against the DSM-5. Only 48.7 percent of the claims were considered accurate by at least one of them. The most common mischaracterization was presenting reasonably normal human behavior, like occasionally losing concentration, as a symptom of ADHD. Then they showed videos to 843 young adults aged 18 to 25, 79 percent female, of whom 421 were self-diagnosed with ADHD and 198 had a formal diagnosis. The self-diagnosed group was the most likely to recommend the videos to others as education.

A separate review from the University of East Anglia, covering 27 studies and more than 5,000 posts and videos, found the same shape across platforms: more than half of TikTok videos about ADHD contained inaccurate or scientifically unsupported claims, autism content was inaccurate 40 to 41 percent of the time, and TikTok's overall misinformation rate, near 35 percent, ran higher than the cross-platform average of about 26 percent.

So the feed is a bad diagnostician. But the people watching it are not stupid, and mocking them misses the story. A label does three real jobs. First, explanation: it gives a name to a life of friction, to years of losing keys, missing deadlines, and feeling behind for reasons you could not name. Second, community: it hands you an in-group, the same belonging machinery from the bottle piece, a group where your traits are normal instead of weird. Third, legibility: a word other people recognize, which means you do not have to explain yourself from scratch every time.

Here is the paradox that ties this series together. The culture in piece one punishes difference: do not be the odd one out, do not get ridiculed, buy the same bottle. The culture in piece two dismisses difference with a word: the ick. And yet this same culture rewards one particular kind of difference, if it arrives with a shared label and a shared feed. Claiming AuDHD, the term for co-occurring autism and ADHD, is difference made safe by being shared. It is the one form of being different that comes with a community attached, which is exactly why it spreads.

The line between recognition and diagnosis is where the piece has to be careful, and a book on exactly this problem, AuDHD or Not? by Theo Lloyds Gaius, offers four questions that separate a clinical picture from relatable content: is it lifelong, is it pervasive across settings, does it cause real functional impairment, and is it better explained by something else? That last question does heavy lifting, because anxiety, burnout, trauma, OCD, and sensory sensitivity can all look like the social media version of AuDHD. A sixty-second video cannot sort that out. Only a real evaluation can, and that evaluation checks when the difficulties started, whether they show up in more than one area of life, how much they get in the way, and what else could explain them.

And the honest both-sides version: some of this is real recognition. People, especially women, who were missed by older diagnostic habits are finding language for experiences they actually have. The study sample itself, 79 percent young women seeking answers, tells you who is doing the seeking. Fault the machinery that sells certainty in sixty seconds, not the people looking for an explanation. This post discusses a trend. It is general information only, not medical advice, and it does not diagnose anyone. If you recognize yourself in these videos, a qualified professional is the person who can sort out what it means.

Thread two: why language shrank into verdicts

Now the linguistics, because the label wave and the language machine are the same story. Linguist Gretchen McCulloch argued in her 2019 book Because Internet that internet conversations are structured by the shape of their platforms, that emoji stand in for gesture, and that memes are collaborative authorship going back centuries. The point is simple and deep: the app is not just where language happens, it is part of what shapes it.

TikTok proves her point at speed. Researcher Xu's study of "it's giving" shows users compressing "giving off a certain vibe" into "it's giving," dropping "off" and then "vibe," and building a whole new syntax around the verb "give." What used to take decades for a phrase to move into everyday use now takes a couple of years. And the algorithm helps choose: researchers writing on algorithmic sociolinguistics note that TikTok's For You Page privileges slang embedded in popular sounds, hashtags, and captions, so the machine, not just the people, selects which words spread. Terms ignite in days and burn out fast. "Cringe" drifted from secondhand embarrassment to inauthenticity to outdated, all by being remixed.

Then there is the asymmetry the user named, and it checks out. The speaker performs: face, voice, editing, sound, a whole production. The commenter gets about 150 characters, according to current platform guides, and TikTok itself does not publish a comment limit, which tells you how little the reply box matters to the design. A bio gets 80 characters. A caption gets thousands, but only the first line or two is ever seen. So the reply cannot argue. It can only react, label, or tag. Voice depletes into verdicts: ick, basic, AuDHD. One-word verdicts are what fit in the box, and the box is the whole conversation for most people.

And then the transactional turn. In a creator economy, the speaker is always, at some level, selling: attention, follows, a product, a link, a course. Language optimized for retention is language that hooks fast, verdicts fast, and travels fast. When everybody is selling something, words become packaging: short, punchy, portable. Slang proliferation is not decay. It is adaptation to a market where attention is the currency and a word that cannot travel cannot survive. The cost is that nuance does not fit in 150 characters or a fifteen-second hook, so complex things, a diagnosis, a person, a treatment, get compressed into labels. Notice what just happened: the label from thread one spreads through exactly the machinery from thread two. "AuDHD" is a diagnosis word and a slang word at the same time, identity and vocabulary in one package.

The beauty version, and the way out

The same feed sells treatments in the same sixty-second certainties: a before and after, a verdict, a link. The machinery does not care whether it is selling a label or a syringe. Verified Aesthetics exists to be the slow lane: checkable claims, sources you can open, credentials you can verify, and prices you can compare, instead of a verdict you are supposed to swallow whole. Lock in to the question behind every word the feed hands you: is this explaining you, or selling to you? If it is explaining you, keep it and check it with a professional. If it is selling to you, at least know you are being sold to. That distinction is the whole glow up, from a feed that labels you to a mind that chooses for itself.
