Fermentation byproduct suppresses seizures in nerve agent poisoning

A compound found in trace amounts in alcoholic beverages is more effective at combating seizures in rats exposed to an organophosphate nerve agent than the current recommended treatment, according to new research published Read more

Post-anesthetic inertia in IH

A recent paper from neurologists Lynn Marie Trotti and Donald Bliwise, with anesthesiologist Paul Garcia, substantiates a phenomenon discussed anecdotally in the idiopathic hypersomnia (IH) community. Let’s call it “post-anesthetic inertia.” People with IH say that undergoing general anesthesia made their sleepiness or disrupted sleep-wake cycles worse, sometimes for days or weeks. This finding is intriguing because it points toward a trigger mechanism for IH. And it pushes anesthesiologists to take IH diagnoses into Read more

Cell therapy clinical trial in stroke

Emory neurosurgeon Robert Gross was recently quoted in a Tennessee newspaper article about a clinical trial of cell therapy for stroke. He used cautionary language to set expectations.

“We’re still in the very early exploratory phases of this type of work,” Gross told the Chattanooga Times Free Press. “In these cases, a significant area of the brain has been damaged, and simply putting a deposit of undifferentiated cells into the brain and magically thinking they will rewire the brain as good as new is naive. None of us think that.”

A more preliminary study (just 18 patients) using the same approach at Stanford and University of Pittsburgh was published this summer in Stroke, which says it was the “first reported intracerebral stem cell transplant study for stroke in North America.” The San Diego Union Tribune made an effort to be balanced in how the results were described:

Stroke patients who received genetically modified stem cells significantly recovered their mobility… Outcomes varied, but more than a third experienced significant benefit.

The newspaper articles made us curious about what these cells actually are. They’re mesenchymal stromal cells, engineered with an extra modified Notch gene. That extra gene drives them to make more supportive factors for neurons, but it doesn’t turn them into neurons. Read more
