Facial Palsy :
Facial palsy is a condition that causes weakness or paralysis of the muscles of the face on one side. The condition arises when the facial nerve is damaged which may be due to inflammation. Bell's palsy is the most common type of facial palsy. The cause is mostly related to the herpes virus and other viral infections. Other causes for facial palsy include stroke, brain injury, infections, tumors, or other neurological conditions. The symptoms can consist of drooping of the face on one side, inability to shut the eye, loss of facial expression, or drooping of the mouth, as well as sometimes pain or numbness. The condition might develop suddenly or with loss of taste or sensitivity on one side of the face. Treatment depends on the cause. For Bell's palsy, most common treatments involve medications like corticosteroids to reduce inflammation and fasten recovery time and physical therapy, which may help the return of muscle strength again. Majority of the patients with facial palsy recover fully although recovery may take many weeks or months.
