Cerebral infarction can cause facial palsy, but not all facial palsy is caused by cerebral infarction. There are usually two types of facial palsy, one is peripheral facial palsy and the other is central facial palsy. Usually central facial palsy only presents symptoms below the eyes, i.e. one side of the mouth is crooked and drooling, while peripheral facial palsy will also include symptoms above the eyes and eyes, including difficulty in closing the eyes, difficulty in wrinkling the forehead, etc. Usually, cerebral infarction occurs mostly in the cerebral hemisphere, and the most frequent is central facial palsy. Only a very few cerebral infarctions occurring in the pontine part of the brainstem may cause peripheral facial palsy, but the chance of occurrence is low. Therefore, after the occurrence of facial palsy, it is necessary to go to the neurology department of a hospital, where a specialist will evaluate the condition, do the necessary head MRI and other tests to determine the condition, and give appropriate treatment to prevent the condition from progressing and developing sequelae.
