Could a psychedelic drug help the brain recover from mild injuries? New research suggests that psilocybin, the mind-bending ingredient in magic mushrooms, might protect the brain from the damage caused by minor head impacts.

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 application for psilocybin — a drug that's already been explored for a range of other conditions, including depression, PTSD and anorexia.

Live Science spoke with study co-author Argel Aguilar-Valles, an associate professor of neuroscience at Carleton University in Ontario, about the new study and how the research might eventually translate to treatments for repetitive head injuries.
