The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
Additionally, enhanced learning and working memory was improved, but only if sulfurophane was administered within 1 hour post injury.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

For example, when administered by injection following TBI, sulfurophane has been demonstrated to attenuate bloodb brain barrier per permeability, which means the body is better able to control what is and is not allowed to enter the brain, as well as a reduction in cerebral edema regardless of how soon after the injury the sulfurophane was given.
Putting aside heat shock proteins for a moment, sulfurophane's activation of NRF 2 in addition to protecting against neurodegenerative diseases and delaying brain aging in general also has special relevance for traumatic brain injury because traumatic brain injury also has a very important inflammatory and oxidative stress components to it.
