Estudio neurofisiológico multimodal en las ataxias espinocerebelosas con herencia autosómica dominante de tipo SCA2 y SCA3

SCA2 is a model of sensory neuronopathy with central and peripheral axonopathy. Studies of brain-stem pathways show a higher incidence of abnormalities in SCA2 patients. SCA3 patients show major changes in the central somatosensory pathway with relative normality of the electroneurography. The masseter reflex was the most useful test in the differential diagnosis between both genotypes.
