The exact cause of the disorder is unknown.The organization reports that unexplained sensations are often the first sign that something is wrong, and often times they disappear before major, longer-term symptoms occur. Those may include difficulty with eye muscles and vision, problems swallowing, speaking or chewing and severe pain.It affects about one in 100,000 people each year, and while there’s no cure, about 70% of sufferers eventually experience full recovery, NINDS reports.Copyright © 2019, ABC Audio.
