At least 80% of opioid overdoses aren’t fatal, WVU researchers want to know how they affect the brain
The vast majority of people who overdose on an opioid will survive the experience. Yet scientists know little about how nonfatal overdoses affect the brain and cognition. WVU School of Medicine researchers Erin Winstanley and James Mahoney systematically reviewed journal articles that examined the topic. Overall, the studies supported a link between overdose, brain abnormalities and cognitive impairment, but more research—with more precision—is needed. Their findings appear in Drug and Alcohol Dependence.
