One night a little more than two years ago, a 24-year-old man was rushed into the emergency room at Tulane University Medical Center in Louisiana. He was extremely agitated and hallucinating.
Dr. Corey Hebert figured the man was on drugs, probably PCP or a stimulant. But a few minutes later, the man became paranoid.
"He started doing some self-mutilating actions [and] was pulling out his eyebrows and eyelashes," Hebert tells weekends on All Things Considered host Laura Sullivan.
