Question
For the past few days, my facial muscles have been twitching involuntarily. This morning, I woke up to find that I have facial paralysis. What are the main causes of facial paralysis?
Answer
The common causes of facial paralysis include several types: first, peripheral facial paralysis, which is caused by facial neuritis, often due to exposure to cold or viral infection leading to neuritis; second, central facial paralysis, usually caused by brain inflammation, such as cerebral infarction, brain tumors, etc. In treatment, there are certain differences between peripheral and central facial paralysis, and treatment should be conducted after the cause is identified.
