Electrical stimulation of the brain could help stroke patients avoid potentially dangerous problems with swallowing, preliminary research indicates.
The treatment has only been tested in a small number of patients and needs further exploration. Still, the findings published online March 24 in the journal Stroke are "encouraging," said Dr. Larry B. Goldstein, director of the Duke Stroke Center at Duke University Medical Center.
An estimated 795,000 people suffer a stroke each year in the United States, and most of them survive, according to the U.S. Centers for Disease Control and Prevention. But many lose some of their ability to swallow, a problem known as dysphagia.
