Abstract

Sporadic late-onset cerebellar ataxia of unknown cause is considered a neurodegenerative disorder whose underlying mechanisms are still unknown. To identify antineuronal autoantibodies, immunohistochemical and immunoblotting techniques were performed in 67 patients with sporadic cerebellar degeneration of unknown cause. Elevated P/Q-type voltage-gated calcium channel (VGCC)-specific antibodies were found in eight patients (11.9%). There was no hint of a paraneoplastic disorder in any of the patients. The present findings suggest an autoimmune contribution to the pathophysiology of a subgroup of sporadic late-onset cerebellar ataxia.
