Sulforaphane

Recent studies suggest that Nrf2-mediated signaling, which controls the expression of many genes responsible for protecting against oxidative stress is regulated by sulforaphane, a compound contained within broccoli.
Other studies have shown that sulforaphane offers cellular protection in several models of brain injury. When administered following traumatic brain injury (TBI), sulforaphane passed through the blood-brain barrier and reduced cerebral edema.
