Stiff Person Syndrome.

Stiff person case misdiagnosed as conversion disorder: A case report

Background: Stiff person syndrome (SPS) is a rare neurological disease resulting in stiffness and spasm of muscles. It initially affects the axial muscles and then spread to limb muscles. Emotional stress exacerbated the symptoms and signs of the disease. The pathophysiology of the disease is caused by the decreased level of the glutamic acid decarboxylase (GAD) activity due to an autoantibody ...

Novel use of dual immunomodulation for treating stiff-person syndrome, cerebellar variant.

Stiff-person syndrome is an autoimmune syndrome defined by muscle spasms and rigidity of proximal and axial muscles. Glutamic acid decarboxylase is the autoantigen found in 60%–80% of stiff person syndrome patients. Stiff person syndrome, cerebellar variant was characterized in a subpopulation of patients (5 of 38) with stiff person syndrome and concomitant cerebellar dysfunction and confirmed ...

Stiff person syndrome.

Recognizing stiff person syndrome is clinically important. It is uncommon, characterized by body stiffness associated with painful muscle spasms, and varies in location and severity. It is subdivided into stiff trunk versus stiff limb presentation, and as a progressive encephalomyelitis. Stiff person-type syndrome also reflects a paraneoplastic picture. Most patients demonstrate exaggerated lum...

Stiff person syndrome presenting with sudden onset of shortness of breath and difficulty moving the right arm: a case report

Although considered a rare disorder, stiff person syndrome is likely to be under-diagnosed due to a general lack of awareness of the disease in the medical community.
