A case report of patient with cerebellar variant of stiff person syndrome

Abstract

Stiff person syndrome (SPS) is a rare autoimmune neurological disorder with antibodies against antigens involved in neurotransmission of gamma-aminobutyric acid (GABA). About 10% of patients with SPS may develop ataxia. This cerebellar variant is a distinct subset of SPS with more severe and complex clinical phenotype. We report the clinical, neuropsychological and neuroradiological findings in a 39-year-old female with cerebellar variant of SPS.
