Patients were recruited from  BACKGROUND The high prevalence of gluten sensitivity in patients with stiff-person syndrome (SPS) lead us to investigate the relationship between gluten sensitivity and GAD-antibody-associated diseases. Nearly all autoimmune diseases are associated with circulating autoantibodies, which may also be found associated with non-related illnesses and in healthy individuals. , Sanders, D. 10 Jun 2007 Conclusion: Our findings provide the first in-vivo evidence of positive GAD antibodies in chronic psychotic disorders and potentially may be used as a screening for these disorders. 30 May 2017 The pathophysiology of the disease is autoimmune. demonstration of an increased intrathecal synthesis of GAD-ab is important to confirm that the GAD autoimmunity is related to the neurological syndrome, especially when there  that CNS disorders, often without associated tumours, can be antibody mediated and benefit from immunomodulatory therapies.
