4/14 What We've Been Saying All Year: A Scientific Synthesis

This week DNA is doing something harder: looking back at everything we've discussed since September and asking what it adds up to. Since our first meeting we've covered what neurodiversity actually means, executive function, accessibility policy, chronic illness, medical gaslighting, ADHD diagnosis, memory, philosophy of disability, universal design, sleep, neuroimmune conditions, emotional dysregulation, interoception, polyvagal theory, masking, late diagnosis, medication metabolism, and the double empathy problem. Each session introduced a new piece.

This week we figure out what they say together. The question we're sitting with: if you had to explain to a Duke administrator, a professor, or a health provider why neurodivergent students are struggling, using everything we've read and discussed this year, what would you actually say?

The argument DNA has been building: We didn't plan it this way in September. But looking back, almost every session has been adding evidence to the same underlying claim:

Neurodivergent struggle is not a personal failure. It is a biological and social mismatch between neurodivergent bodies and minds, and the institutions they are asked to function inside.

Here's how the pieces connect:

• It starts with what neurodiversity actually means. Our first session grounded everything in Earp et al.'s framework: neurodiversity isn't a feel-good term, it's a claim about human variation that has real implications for how we design institutions, deliver healthcare, and understand distress. Everything that followed was an elaboration of that claim.

• The body is misaligned with the schedule. Our two-part sleep series showed that neurodivergent people have genuinely different circadian timing, higher rates of sleep disorders, and nervous systems that don't respond to standard sleep advice because the underlying biology is different. The 8am lecture isn't a minor inconvenience. It's a biological conflict.

• The nervous system doesn't regulate the same way. Our sessions on executive function, emotional dysregulation, and memory showed that planning, working memory, inhibition, emotional response, and retention don't work the same way across neurotypes. The entire architecture of university life, deadlines, lectures, exams, office hours, assumes they do.

• The body is paying an immune cost. Our neuroimmune sessions, grounded in Quadt et al., showed that neurodivergent traits predict chronic disabling fatigue through inflammatory mechanisms. Brain fog, sensory overload, and executive shutdown during high-demand periods aren't motivation problems. They have measurable physiological substrates.

• The body is also paying a pharmacological cost. Our medication metabolism session showed that the same autonomic and connective tissue differences that shape neurodivergent experience also change how medications are absorbed, metabolized, and tolerated. When neurodivergent patients report unusual drug responses, it's often not in their heads.

• The body's internal signals aren't getting through clearly. Our interoception sessions showed that the gap between how well neurodivergent people actually detect internal signals and how well they think they do is measurable and consequential. People don't catch the warning signs of exhaustion, hunger, or overwhelm until they're already past the threshold. The OT session made that concrete in a room full of people who felt it in real time.

• The nervous system is shaped by felt safety. The polyvagal theory session raised a real question regardless of where the biological debate lands: what does chronic threat exposure do to a body over time? Neurodivergent students navigating spaces where they don't feel safe are not operating from the same physiological baseline as students who do.

• Diagnosis shapes identity, and its absence does too. Our late diagnosis and identity session showed that struggling for years without language for why, then receiving a diagnosis, restructures how people understand their entire history. And our sessions on race, medical sociology, and ADHD in the 2020s showed that who gets diagnosed, when, and by whom is shaped by race, gender, and socioeconomic status in ways that compound every other disadvantage on this list.

• Medical gaslighting is a structural problem, not a series of bad appointments. Our two sessions on medical gaslighting showed that neurodivergent and chronically ill patients being dismissed and told their symptoms aren't real is consistent enough across populations to be a pattern. Chloe Schwartz's session on EDS put a face and a body on that pattern. It shapes whether people seek help at all, and whether they trust the people helping them.

• The philosophy underneath all of it matters. Our two-part philosophy of disability series asked the hardest version of the question: if neurodivergence is part of human variation, what does that mean for how we approach cure? Who benefits from normalization, and who pays for it? Universal design isn't just a pedagogical framework. It's an answer to that question.

• Masking is where all of it converges. Hull et al. showed what camouflaging costs. Botha and Frost showed that minority stress, not autism itself, predicts mental health outcomes. Raymaker et al. named burnout as the endpoint. The circadian disruption, the immune cost, the interoceptive fog, the dysregulated nervous system, the executive demands of performing neurotypicality in spaces that weren't built for you: masking runs through all of it simultaneously.

• And the problem was never located inside neurodivergent people. Milton's double empathy problem, empirically supported by Crompton et al., reframes the entire year. Social difficulty is a mismatch between neurotypes, not a deficit in one of them. Every accommodation, intervention, and support structure that places the burden of change entirely on the neurodivergent student is answering the wrong question.

  
  

What we'll be doing

We'll work in small groups around four questions, then come back together.

• If you could show a Duke health provider one thing from everything we've covered this year, what would it be and why?

• DNA already changed the attendance policy. Based on everything we've read, what should be next?

• Which two sessions from this year do you think belong together most, and what do they say when you read them side by side?

• What's the biggest gap in what we covered? What did we not talk about that we should have?

We'll close by trying to answer one question together as a room: what is DNA's argument?
