Spinocerebellar ataxia type 2 with levodopa-responsive parkinsonism culminating in motor neuron disease

Authors


Abstract

We describe an exceptional spinocerebellar ataxia type 2 (SCA2) phenotype combining cerebellar ataxia, levodopa-responsive parkinsonism, and motor neuron symptoms. We conclude that motor neuron symptoms and signs may be a striking manifestation in SCA2, masking pre-existing cerebellar and extrapyramidal semeiology. © 2004 Movement Disorder Society
