What is Bell’s Palsy?
(Symptoms, Causes & Treatment)
According to the National Institute of Neurological Disorders and Stroke, Bell’s palsy identifies a form of temporary facial paralysis resulting from damage or trauma to the facial nerves. When Bell’s palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis.
Damage to the facial nerve or a disruption in its function can lead to many problems. Symptoms of Bell’s palsy can vary from person to person and range in severity from mild weakness to total paralysis. These symptoms may include twitching, weakness, or paralysis on one or rarely both sides of the face. Other symptoms may include drooping of the eyelid and corner of the mouth, drooling, dryness of the eye or mouth, impairment of taste, and excessive tearing in one eye. Most often these symptoms, which usually begin suddenly and reach their peak within 48 hours, lead to significant facial distortion.
