Even mild head impacts that don't count as concussions can raise the risk of neurodegenerative disorders such as chronic traumatic encephalopathy (CTE), so finding an effective treatment for these blows could be useful for warding off debilitating conditions down the line.The new research, published in the journal Communications Biology, included only lab rats, so there's more work to be done to translate the findings to humans. But the early results hint at a new applic...
