You know it has been quite along time ago now, I had one neurologist try and tell me he thought I had Stiff Person Syndrome due to all my symptoms, and after some extensive EMG and nerve conduction studies, but other doctors disagreed and was I never formally diagnosed. To my knowledge they never checked my GAD antibodies. I do suffer from muscle spasms through out my body and take Baclofen to control them. I found a web site with some good information about
it, here is the link.
