Palatal myoclonus is a fast spasm (contraction) of the muscles in the roof of the mouth.
Palatal myoclonus is most often due to damage (lesions) on brain nerve pathways. Stroke is the most common cause. The problem most often develops about a year after the stroke occurs. Other conditions such as multiple sclerosis, trauma, or tumor may also lead to this problem.
