MED BRIEFS Epilepsy study involves neurotransmitters

Mayo Clinic in Scottsdale, Ariz., is researching a new procedure to surgically place a Responsive Neurostimulator (RNS) in the brain, intending to suppress seizures in patients with epilepsy.

The technique is for patients who don't respond to traditional therapy. Epilepsy, a chronic disorder of the brain, affects nearly three million people in the U.S., the clinic says. The brain device, similar in size to a wristwatch, is implanted under the scalp and connected by one or two wires to the brain. RNS is hoped to possibly replace the need to remove seizure-causing brain tissue. Patients are being enrolled in a study and will be followed for two years. For information, call 480-301-8260.

Green tea may help fight cancer

Mayo Clinic Women's HealthSource says there's increasing evidence that green tea offers health benefits. Recent studies show "polyphenols," compounds in green tea, may protect against certain cancers and help destroy cancer cells.

Another component helps kill the most common form of leukemia in the U.S. Epigallocatechin-3-gallate kills leukemia cells by interrupting communication signals they need to survive, HealthSource says.


"While it's too early to recommend green tea to prevent or treat leukemia, drinking it is unlikely to cause health problems," HealthSource reports.
