Recent research indicates that levels of education protects against damage after head trauma.
“The study looked at the medical records of 769 adults who suffered traumatic brain injuries serious enough to require an inpatient hospital stay and rehabilitation. A year after the injury, just 10 percent of people who didn’t finish high school had no disability, compared with 39 percent of people with enough years of education to have received a college degree. People with advanced degrees did even better.”
