title: A patient with post-traumatic stress disorder developing stiff person syndrome: is there a correlation?
abstract: Stiff person syndrome (SPS) is an uncommon disorder characterized by progressive muscle stiffness, rigidity, and axial muscle spasms. It is presumed to be an autoimmune process, with glutamic acid decarboxylase antibodies present in most cases. Here, we present a case report of a patient diagnosed with post-traumatic stress disorder (PTSD) acquired by sexual trauma and by exposure to the severely wounded soldiers she attended as a nurse. Subsequently, she developed SPS confirmed by serology. The possibility of an association between PTSD and SPS is theorized, given their relationship to the GABAergic system. Further studies examining the relation between PTSD and SPS should be initiated.
