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

🧠🫀 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/s4159…

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.2…

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/about/newsr… pnas.org/doi/abs/10.107… @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-ap… #StrokeAwareness #DigitalHealth #Innovation #ECHAS

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

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/10.10…

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 -…

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/

The bacteria in your gut depend on where you are in the social network. And the microbes within us treat our social networks as the extended environment in which they thrive. They can spread from person to person. New #HNL work out today in @Nature. 1/

Great talk this week at our NCC grand rounds by @AmarDhand from @MGHNeurology on very interesting work on the relationship of social networks on stroke prevention, treatment and methods to quantify social connectomes. Checkout ⬇️ his work in @NatureComms @SMuehlschMD

My ICU has an open door. Families are encouraged to stay in the room when we examine the patient, and have access 24 hours a day. They love it. In this Brazilian RCT liberal ICU access (12 hrs/day) was associated with fewer PTSD symptoms among family members than restrictive…

Intriguing work by @lilin_tong @RuchitVP with the partnership of @AmarDhand highlighting how connected a hospital is to a network of hospitals impacts #brain-metastasis patient outcomes beyond hospital size and patient characteristics @MGBneurosurgery @MassGenBrigham @harvardmed

Good time at the NIH convening with researchers, program officers, and directors interested in social connection and health. My colleagues and I are suggesting ways to operationalize for patients with brain disorders via moonshot ideas in measurement and intervention.

This paper continues the theme of hospital networks, and how the ways hospitals are connected impact patients outcomes. This is a powerful idea that needs more study and application to improve quality and cost of care.

I have a wish to find answers for the questions my patients ask me and which I cannot answer. Seeing patients is a gift and a privilege You can also ‘thrive’ as you put it by never teaching but curiosity and passing on knowledge are important for me and have kept me fresh
