Drugs that quell brain inflammation reverse dementia

Posted by in categories: biotech/medical, life extension, neuroscience

Drugs that tamp down inflammation in the brain could slow or even reverse the cognitive decline that comes with age.

In a publication appearing today in the journal Science Translational Medicine, University of California, Berkeley, and Ben-Gurion University scientists report that senile mice given one such drug had fewer signs of inflammation and were better able to learn new tasks, becoming almost as adept as mice half their age.

“We tend to think about the aged brain in the same way we think about neurodegeneration: Age involves loss of function and dead cells. But our new data tell a different story about why the aged brain is not functioning well: It is because of this “fog” of inflammatory load,” said Daniela Kaufer, a UC Berkeley professor of integrative biology and a senior author, along with Alon Friedman of Ben-Gurion University of the Negev in Israel and Dalhousie University in Canada. “But when you remove that inflammatory fog, within days the aged brain acts like a young brain. It is a really, really optimistic finding, in terms of the capacity for plasticity that exists in the brain. We can reverse brain aging.”
