My latest with the @nymedcollege @WMCHealth neuroscience team: Levetiracetam was associated with reduced risk of early seizures (<7 days) among severe TBI patients (GCS 3-8), but did not protect from early seizures after mild TBI, or from late post traumatic epilepsy (<1 year). These results are very similar to the landmark Temkin paper looking at phenytoin prophylaxis after severe TBI.

What brain circuits do we need to target to improve symptoms of bipolar disorder? With support from @BD2Discoveries our team of psychiatrists, neurologists, neurosurgeons, and neuropsychologists will find out! @Brain_Circuits @MGBResearchNews
🧠 Breakthrough precision mapping: @foxmdphd and his BD² Discovery Research team at @BWHNeurology are pinpointing which brain circuits drive specific bipolar symptoms—enabling targeted neuromodulation & brain stimulation treatments.

Scientists at Oxford University have demonstrated, for the first time, that a key emotional centre deep in the human brain directly influences how we interpret ambiguous social cues. Find out more ⬇️ ox.ac.uk/news/2026-04-02-oxf…

Congratulations @shansiddiqi and Joe Taylor @Brain_Circuits on their paper in @molpsychiatry demonstrating the translational power of LNM and brain circuit therapeutics. It has already changed clinical TMS practice @BrighamWomens @harvardmed.

In the Human Epilepsy Project multicenter cohort study, most individuals with newly diagnosed focal #epilepsy required over a year and multiple antiseizure medications to become seizure free. ja.ma/43vP03Q

A true pioneer in the field of neurophysiology & EEG. What a loss! Every EEGer should read this classic paper by Klass and Westmoreland. onlinelibrary.wiley.com/doi/… #NeuroX #Epilepsy #Neurophysiology
We lost a legend in neurology, Dr. Barbara Westmoreland 🔹 described EEG findings like periodic sharps in HSV 🔹 consummate neurophysiology educator 🔹second woman on staff @MayoClinicNeuro 🔹 president of AES and ACNS. Thank you, Dr. Westmoreland, for paving the way

Japan just approved stem cells for Parkinson’s disease. How will it work? Stem cells are special cells that can develop into other types of cells. In this case they are turned into dopamine-producing brain cells designed to replace the cells lost in Parkinson’s disease. Sawamoto and colleagues described in a new paper in Nature one of the first phase I/II clinical trial using induced pluripotent stem cell derived dopaminergic progenitor cells transplanted into the brains of folks living w/ Parkinson’s disease. These cells are generated from iPS cells and implanted into the putamen where dopamine neurons normally function. Key Points: - Seven folks w/ Parkinson’s disease received bilateral transplantation of dopaminergic progenitor cells derived from iPS cells into the putamen and were followed for 24 months. - The transplanted cells survived, produced dopamine, and imaging revealed a roughly 44 percent increase in dopamine related activity in the putamen. - The procedure appeared safe w/ no tumors or graft overgrowth and several participants experienced improvements in motor scores on Parkinson’s rating scales. My take: Japan has a unique regulatory pathway for regenerative medicine that allows conditional approval once safety and early signals of benefit are demonstrated. For the therapy to advance in Japan data will be collected over the next 7 years. This paper represents an important milestone because it shows that lab grown dopamine cells can survive in the human brain and begin producing dopamine. The big questions ahead will be durability, patient selection, and whether the next 7 years of experience will confirm meaningful and sustained clinical benefit. Here are 5 points that resonated w/ me: 1- Parkinson’s disease is caused by the loss of dopamine producing neurons and this therapy attempts to replace those missing cells. 2- The transplanted cells are generated from induced pluripotent stem cells which are adult cells reprogrammed to behave like embryonic stem cells. 3- Brain imaging revealed new dopamine activity in the transplanted region suggesting the cells were functioning. 4- Safety remains the first hurdle and this trial showed no tumors or uncontrolled cell growth over two years of follow up. 5- The future will likely combine cell therapy w/ medications, rehabilitation, and possibly gene therapy to maximize benefit for folks living w/ Parkinson’s disease. Here is the Nature paper that set the stage for the recent approval. nature.com/articles/s41586-0… #parkinson @ParkinsonDotOrg @FixelInstitute

Should residents & fellows bill? A single resident can provide >$300k/yr in uncompensated care due to outdated @CMSGov rules. Our @NEJM paper proposes a competency-based framework to capture this revenue, improve trainee pay, and offset massive debt. #MedTwitter #MedEd #GME

Mark this day as a major turning point for #Dravet syndrome and the treatment of #epilepsy in general! Today the New England Journal of Medicine published results from @StokeTx phase 1/2 studies of zorevunersen demonstrating evidence of impressive seizure reduction on top of best standard of care AND improvements in non-seizure outcomes such as communication in children with Dravet! The era of disease modification is upon us for genetic epilepsies and this is just the beginning! nejm.org/doi/full/10.1056/NE…
