Yes definately. I was hospitalised last month for two weeks with "fitting" that I couldn't control. I'm not epileptic, but my whole body would twitch. The first night it was for 4 hours. I eventually ended up on a walking frame. After being moved to a psychiatric hospital, it was found to be stress and panic. My doc had a term for why I couldn't walk and needed the frame. Plus I have had abdominal spasms for two years with no known cause. I can now stop them using breathing techniques. The doc thinks they were stress/panic as well. So yes there is a link.
