Abstract

We tested the hypothesis that a recently developed transgenic rat model of Huntington's disease (tgHD rats) showed an age-and genotype-dependent change in psychomotor performance and in the frequency of choreiform movements similar to HD patients. Wild type and tgHD (homozygotic and heterozygotic) rats were behaviorally tested at an age of 15 and 20 months. Our results show that tgHD rats exhibit an age-, and genotype-dependent deterioration of the psychomotor performance and choreiform, symptoms, closely mimicking the clinical time course changes of psychomotor symptoms of HD patients. These data provide further experimental evidence that the tgHD rat can be considered as a relevant animal model of HD.
