AI and Motion Tracking: A New Era for Autism and ADHD Screening?
By Real Ray C on
We all understand that obtaining a diagnosis for autism or ADHD can be a long process. In some regions, families may wait for over a year. These delays can prevent children from receiving the support they need immediately.
But could technology be the solution?
Researchers at Indiana University have been experimenting with an artificial intelligence (AI) system that observes children's movements, specifically their hand movements during a simple touchscreen task, to identify signs of autism and ADHD.
Children wear tiny wireless motion sensors while tapping or reaching on a screen. These sensors capture highly detailed movement data: acceleration, rotation, and even minute wobbles that are invisible to the naked eye.
The AI was trained on this motion data and learned to distinguish between neurotypical children and those with autism, ADHD, or both. On average, it was accurate about 71% of the time. While not perfect, it's quite impressive for preliminary research.
What's intriguing is that the system doesn't just provide a "yes/no" diagnosis. It also gauges the severity of symptoms by analyzing the randomness or variability in movements. Children with more severe autism tended to exhibit more irregular motion patterns.
The ultimate goal here isn't to replace doctors. Rather, it's about providing clinics, schools, and even telehealth providers with a quick, affordable, objective screening tool. Ideally, this could lead to quicker referrals, improved planning, and more personalised support.
Of course, this is just the beginning. The researchers acknowledge that the tool has more difficulty when children have both autism and ADHD, a common, complex combination. And AI is only as effective as its training data, so broader testing is required.
However, I find this kind of innovation thrilling. Diagnosis shouldn't be a privilege reserved for families who can afford countless specialists or live in the right area.
If motion-tracking AI can help us detect neurodivergence earlier and support children sooner while respecting neurodivergent experiences and avoiding medical gatekeeping, that seems like a victory.
💬 What are your thoughts? Would you trust an AI screening tool for early diagnosis? Would you like to see this in schools or clinics? Let's discuss.

Couldn’t agree more. Tech can open the door, but people have to walk through it with care. I’d rather wait an extra year for an AI tool that respects kids than rush out something that gets used as a sorting machine. Let’s push for both speed and soul. ❤️

@Charlotte, @Eli @JugglingNothing
You guys are reminding me that innovation means nothing if it doesn’t come with empathy. If this tech ever rolls out in schools, I hope it comes with parent advocacy training, ND-led feedback, and trauma-informed implementation. - Eli Mercer:
Exactly that. Like, if the system flags a child because they stim in a certain pattern, is it going to treat that as a warning sign, or as a normal part of their regulation? That interpretation matters so much. I love the possibility, but I hope we stay critical and keep the human lens in focus.
- Charlotte:
Yes, Miles! The “who builds it” matters as much as the tech itself. If they’re training the AI using only medicalised, deficit-based models, then we’re just digitizing bias. But if it’s co-designed with autistic and ADHD adults, there’s so much potential to get it right.
- JugglingNothing:
This is fascinating stuff, Ray. I like that it doesn’t replace human experts but adds another layer. If it helps overworked clinics spot kids earlier, that’s a win. But I also hope the AI is built with neurodivergent voices in the room. Otherwise it might just reinforce old assumptions with newer tech.
- Real Ray C:
Eli, yes, exactly, access without gatekeeping. That’s where tech can help if we use it right. It’s wild to think a few data points from hand movements could tell a story that most doctors take hours to interpret. But it also reminds us how much of neurodivergence is rooted in the body, not just the brain.
- Eli Mercer:
Charlotte, totally with you. I had to wait 14 months for a diagnostic appointment as a teen, and by then, so much damage was already done emotionally. If AI had been an option? I can’t even imagine how different things could’ve been. That said, it has to be introduced with consent and not as another system of control. We don’t need more rigidity, just more access.
- Charlotte:
Ray, I find this so hopeful and a little surreal. A few years ago, we were fighting just to get on waitlists; now we’re talking about AI potentially helping kids access earlier support? That's incredible. I’d love to see this in schools, especially in rural areas where specialists are few and far between. My only worry is how it would be introduced. We’d need massive training and ethical oversight.
