Open social networks are better than close-knit ones to get patients to the hospital on time during a stroke. Check out our paper @NatureComms rdcu.be/bqZX0

Grateful to Harvard/MGB Neurosurgery for inviting me to speak on cognitive biases in surgical decision-making. Great to reconnect with @mtlawton of Barrow. Thanks to Ali Sultan, Nirav Patel, and Linda Bi for the invitation and discussions.

MIT professor delivers a brilliant masterclass on how to effectively present your ideas with clarity, high impact and purpose

New paper out today @SciReports: SocialBit, a smartwatch-based, privacy-preserving algorithm to objectively measure social interaction. Validated against human observation, including in patients with aphasia. Presenting today at #ISC2026. rdcu.be/e2hD7

Implication: enhancing emotional support and camaraderie is likely to improve quality of life in patients with ataxia. Kudos to @AmarDhand for developing PERSNET, our RA-now medical student James Concepćion for leading the study, Broadstreet for statistical analysis. @NAF_Ataxia

rdcu.be/eYCXg We examined personal social network metrics in patients with ataxia. Positive relationships, camaraderie, weekly communication, and high levels of emotional support correlate with higher quality of life and better physical function.

"Charcot Redux" - @ajlees has written a magisterial article on Charcot, which gives you something of the man and his context. Essential for anyone needing an introduction. doi.org/10.1093/brain/awaf38…

Academic turf war discussions are stupid because turf wars are a young man’s game. The true differentiator in academia is not field, but quality. A more experienced scholar appreciates a good qualitative study, a solid mathematical model, a sharp « heterodox » insight, or a well-crafted formal theory, regardless of the field. Every time I’ve met a Nobel prize caliber scholar, before or after the prize, I’ve encountered a curious and open minded intellectual. Every time I’ve encounter a turf war zealot, they are a young, mono-disciplinarian holding tight to their new credentials—the foundation of their identity, self-worth, and fledgling status. To be a world class scientist you need to be the former, because if you think your discipline has a monopoly on the creation of knowledge, or of quality, you don’t know the first thing about knowledge creation. Knowledge is non fungible. Lives are short, and science is vast and beautiful. Don’t show your naïveté by being a soldier in a turf war. 🫡

🧠🫀 New in Nature Neuroscience: Stroke recovery involves more than cells and genes—social networks are one powerful factor shaping brain repair. 📊 Beautiful figures show how social, cellular & molecular networks reprogram recovery. Read: nature.com/articles/s41593-0…

In a new study, researchers from @BWHNeurology and colleagues found that childhood experiences shape the brain’s white matter with cognitive effects seen years later. The study was published in @PNASNews. Read more: massgeneralbrigham.org/en/ab… pnas.org/doi/abs/10.1073/pna… @AmarDhand

Excited to see our ECHAS app featured on @WCVB! Our team built ECHAS to help detect stroke symptoms early using smartphone-based tests. Every minute matters in stroke care. Learn more: 🔗 wcvb.com/article/new-app-use… #StrokeAwareness #DigitalHealth #Innovation #ECHAS

Thank you @ScienceMagazine for covering our work of childhood environment and brain-wide white matter signatures. science.org/content/article/…

Adversity was associated with lower white matter integrity and later difficulty with arithmetic & receptive language yet interpersonal resilience was protective. New work out in @PNASNews pnas.org/doi/epub/10.1073/pn…

How do early life social environments impact white matter brain connections and subsequent cognitive abilities? Was fun working on this exciting project led by Sofia Carozza, @AmarDhand @DuncanAstle @Braindoc_MGH @harvardmed @BWHNeurology

New in @PNASNews: Childhood social environments leave brain-wide white matter signatures. In 9,000+ youth, we link adversity to structural changes and later cognition—a step toward mapping social networks onto brain biology. doi.org/10.1073/pnas.2409985…

The vigilant stroke neurologist is never fully satisfied with ESUS in older individuals. Rather than repeating holter monitors they consider: - non-stenotic extracranial large artery athero - occult cancer - branch artery disease - aortic arch athero - minor valve disease - LV wall motion abnormalities - carotid siphon disease - consider PFO as etiology in older individuals (doesnt mean you will close) - carotid webs #stroke #MedEd #neurology

Our team carted liquid nitrogen to 18 Honduras villages and persuaded 1,787 people to give us samples of their poop, which we subjected to shotgun metagenomic sequencing to discern species and strains of gut microbes. This was not easy in any way. 5/
