An Overview of Bell's palsy
Bell's palsy is a condition where the facial nerve is affected leading to facial paralysis on one side of the face.
Symptoms can mimic a stroke in that there is sudden onset of trouble speaking, drooping of one side of the face and trouble keeping food in the mouth.
What differentiates Bell's palsy from a stroke is that the forehead muscles are also affected unlike in a stroke where the forehead muscles are not affected.
While the exact cause of Bell's palsy is not known, it is suspected to occur after exposure to certain viruses or lyme's disease.
Treatment consists of antiviral medications and steroids for a week. Because patients can have trouble closing their eyes, they are prone to corneal abrasions so eye lubricants and eye patches for sleeping should be used.
