facial twitching on right side of face in the cheek area and mouth.

Hello there,

Well, first of all this can be various things. Muscle twitching is sometimes benign and it can be caused lack of sleep so make sure that your husband is sleeping enough. Another reason for muscle twitching can be excessive caffeine so if he is consuming too much talk with him to cut back or stop. This is better option and usually it will stop on its own.

There is one other possibility and that is very hard disease for which there is no cure. Involuntary movement is characteristic for Alzheimer's disease. If you have noticed some other changes in your husband’s behavior take him to the doctor as soon as possible. Good luck and I hope that he will be fine.
