In new research a drug, riluzole, is capable of reversing key genetic changes associated with these conditions. “In aging and Alzheimer’s, the chemical signal glutamate can accumulate between neurons, damaging the circuitry,” Pereira says. “When we treated rats with riluzole, we saw a suite of changes. Perhaps most significantly, expression of molecules responsible for clearing excess glutamate returned to more youthful levels...
