IT'S THE TRADITIONAL WAY TO CURE CERTAIN KINDS OF EPILEPSY.
FOLLOWING THIS TYPE OF OPERATION THE COMPLICATIONS CAN BE WORSE THAN THE SEIZURES.
NOW, THERE'S A NEW HIGH-TECH AND LOW-RISK WAY TO ERASE EPILEPSY.
THAT LAUGHTER ISN'T REAL. IT'S A GELASTIC SEIZURE.
ROBIN AND KHRIS DYSART SAY THEIR SON KEAGAN HAD THE SEIZURES THREE TIMES EVERY HOUR.
A CRANIOTOMY WAS THE BEST CHANCE FOR A CURE. SURGEONS MAY HAVE TO TAKE OUT NORMAL BRAIN TISSUE TO MOVE THE LESION CAUSING THE SEIZURES. COMPLICATIONS CAN INCLUDE PARALYSIS, UNCONTROLLED URINATION AND...
"There were lists of children who have died."
"You can't put back brain that you wish you hadn't taken out."
TO AVOID TAKING OUT ANY BRAIN, DOCTORS ANGUS WILFONG AND DANIEL CURRY OF TEXAS CHILDREN'S HOSPITAL DEVELOPED A LOW-RISK MINIMALLY INVASIVE M-R-I GUIDED LASER SURGERY TO CURE EPILEPSY. KEAGAN WAS ONE OF THEIR FIRST PATIENTS AND THIS IS HIS ACTUAL SURGERY. WITH THIS TINY INSTRUMENT
"It's smaller than the size of a pencil lead."
THE DOCTORS NAVIGATED THEIR WAY TO KEAGAN'S DEEP-SEATED LESION. "Actually it's possibly the worst place you can have a lesion."
WITH THE M-R-I, THEY WERE ABLE TO SEE IN REAL TIME EXACTLY WHERE THEY WERE IN KEAGAN'S BRAIN. THE DOCTORS WATCHED THE LASER DESTROY THE LESION AND CURE KEAGAN'S EPILEPSY.
"That's exactly what's happening and it's really amazing to see."
TODAY KEAGAN'S SEIZURE FREE.
"Now the world has opened up to him."
HE LOVES BASKETBALL.
"I've been practice dribbling."
"Voyager two's been to Mars."
INSTEAD OF HIS SEIZURE-INDUCED GIGGLES.
"We walked around the corner and he was really laughing for the first time we've ever heard him laugh at a TV show."
A BOY'S LIFE FOREVER CHANGED BY A LASER.
TEXAS CHILDREN'S HOSPITAL IS THE FIRST IN THE WORLD TO PERFORM THE M-R-I GUIDED LASER SURGERY TO CURE EPILEPSY.
THE PROCEDURE WAS ADOPTED FROM A TECHNIQUE TO TREAT BRAIN TUMORS.
IT'S NOW BEING USED FOR KIDS AND ADULTS.
THE DOCTORS TELL US SOME OF THEIR PATIENTS GO HOME THE DAY AFTER THEIR BRAIN SURGERY.
