Starr! It’s so confusing and sorry my article didn’t land for you. It has to do with prediction error: when sensory information doesn’t match what the brain expects from prior experience. Autistic thinkers build highly-specific prediction models. So there is more mismatch. (And that is high spend)

Ive been writing on the science of autistic burnout and monotropism. This one goes deep. Krebs cycle, electron transport chain, how we make ATP. And why the panic of running out of air and the panic of overwhelm are the same alarm. aliabreonmd.substack.com/p/the-bioche...

Prediction error, I think. Deep and narrow processing builds deep and narrow (highly specific) predicitons. Highly specific predicitons -> more prediction error -> more signals for cells to respond/prepare. Respond = use ATP run their cellular machinery. Results in less ATP left for clean up.

What does ATP—our cellular energy made in the mitochondria—have to do with autism? Maybe everything. How we spend that currency is where autistic lived experience (the Theory of Monotropism) and the emerging neuroscience of predictive processing converge. substack.com/home/post/p-...

Great article! Empathy is 'tasting' another's emotional experience. People who think alike construct emotions alike, and so overlap more. Empathy tests don't measure a deficit - they measure similarity between constructed experiences. Mismatch, not deficit. That's Milton's double empathy problem.

Your note made me tear up a bit. Because I have been trying to write that book for three years -- about how I as an MD had to completely change how I understood autism and neurodiversity. How the person who needed to change was me.

This is fascinating: "the endothelial cells [around blood vessels in the brain] had half the normal level of a molecule called ATP." ATP = the energy unit used by all cells in the body. Potentially more support for the idea that Autism is a difference processing resource distribution. #Monotropism

What do ADHD and autism actually have to do with attention? The question won't make sense until we stop defining attention as the conscious focus of our mind, and consider it instead as how the whole mindbody notices and responds to the world. www.nytimes.com/2026/09/29/s...

What if A.D.H.D. Isn’t About Attention at All?
Evidence suggests that it really affects what psychiatrists like me call sustained engagement — an important difference in understanding how to think about the condition.

SSRIs can flatten emotion. Burnout recovery may depend on feeling things again. Has anyone tapered off an SSRI (gently, carefully, with support) during autistic burnout? How did it change your recovery? What did you notice?

Like many physicians, I thought of mast cells only as "allergy cells." I had no idea they live in the brain, driving neuroinflammation from stress. Witnessing my autistic son's burnout forced me to look deeper—and it changed everything. aliabreonmd.substack.com/p/meet-the-m...

A great paper on double empathy theory: autistic social challenges aren’t deficits, but a mismatch between autistic and non-autistic communication and experience. The DSM’s deficit-based framing of autism obscures that reality.

Hi Helen! Thank you and I am so happy this piqued your interest. I have been quietly reading your work for the last couple years and so it is wonderful to get to connect with you.

Ezra Klein recently wrote: "Attention is sometimes an act. But first it is an instinct." We think we choose what we notice. But the initial decision was made before conscious awareness arrived. Pulling attention from its natural direction? That takes effort.

It is heartbreaking to see how medical science and autistic lived experience has been pushed aside and made way for fear-based messaging. There is a complex interplay between the immune system, stress biology and sensory procesing but vaccines are not the problem.

Yes!! Autism is fundamentally a difference in how salient (important and interesting) information engages with the attentional networks and interests systems.

Alia Breon, MD @aliabreonmd.bsky.social · 07/12/2025
Yes! It is a difference in how processing resources are distributed. The autistic mind naturally attributes more resources to important and interesting experiences. This deepens processing in some areas, but leaves less resources for others. The theory of monotropism.

We tell autistic kids to stop spinning, stop flapping—stop expressing joy so visibly. When did you last let happiness move through your whole body? Laugh without checking yourself, or swing just for the rush? My autistic son is teaching me to remember.

Autism studies say the autistic brain is over-connected. Others say under-connected. Others: both. Monotropism makes sense of it. Is the Salience Network the neurobiology beneath it? I explore that idea here ⬇️
