Brain stimulation may help stroke patients to swallow

Electrical stimulation of the brain may help patients improve their ability to swallow after a stroke.

Nearly 800,000 people experience a stroke every year. Most of them survive, but many lose some of their ability to swallow. It's a condition called dysphagia.

Researchers at Duke University mildly stimulated the brains of stroke patients through electrodes placed on the scalp. Patients who received the treatment had an easier time swallowing than patients who did not.

Researchers do emphasize that further study is still needed. Their findings appear in the online journal Stroke.
