Researchers at the Mayo Clinic have found an increased incidence of Attention Deficit Hyperactivity Disorder among children exposed to anesthesia more than once before age two. A study published Thursday in Mayo Clinic Proceedings looked at more than 5,000 children born in the Rochester area in the late 1970s and early 1980s. Children who had more than one medical procedure requiring anesthesia were more likely to develop ADHD. "It's a fairly significant effect — it more than doubles your chances," said Dr. David Warner, a Mayo anesthesiologist and one of the observational study's authors.
