Autoantibodies to Glutamic Acid Decarboxylase in a Patient with Stiff-Man Syndrome, Epilepsy, and Type I Diabetes Mellitus

Abstract
Stiff-man syndrome is a rare disorder of the central nervous system consisting of progressive, fluctuating muscle rigidity with painful spasms. It is occasionally associated with endocrine disorders, including insulindependent diabetes, and with epilepsy. We investigated the possible existence of autoimmunity against the nervous system in a patient with stiff-man syndrome associated with epilepsy and Type I diabetes mellitus.
