Jennifer Matthews: It was a day much like this one. Paul Gilliland was out walking with friends. Paul Gilliland: My vision became blurred and my speech became mumbled. That lasted for maybe three minutes. Jennifer Matthews: Paul was having a stroke. Sheryl Gilliland: He had dysfunction in the right hand and arm. Jennifer Matthews: It began in the morning, but he didn't go for help until the afternoon. Dr. Howard Yonas said it was too late for medicine. The stroke had cut off blood for too long. Dr. Howard Yonas: The brain is a computer that is fed not by electricity, but by blood flow. The brain is very demanding. Jennifer Matthews: The orange area in this illustration shows normal blood flow. The blue area show delayed blood flow. To restore it, Dr. Yonas created a bypass and rerouted blood directly to the brain. Dr. Howard Yonas: It just adds a little bit of blood supply to an area of the brain that just needs a little bit more to get out of the gray zone it's sort of living in. Sheryl Gilliland: When he was getting ready to go into surgery, he had very slurred speech. The next day when I saw him, I could understand a lot of what he said, and each day it got better. Jennifer Matthews: Paul still struggles a little with his speech, but his dexterity is back to normal. This is Jennifer Matthews reporting.
