Central facial palsy is often characterized by either hemiparalysis or hemiparesis of the contra-lateral muscles in facial expression. Muscles on the forehead are left intact. Also, most patients have lost voluntary control of muscle movement in the face—however, muscles in the face involved in spontaneous emotional expression often remain intact. Central Facial palsy occurs in patients who are hemiplegic. Such patients not only have dysfunctions in the facial expression but also a difficulty in communication. Other oropharyngeal functions such as sucking, swallowing, and talking are also impaired.
