Abstract/OtherAbstract:
We evaluated the early pathological changes in patients with sporadic cerebellar ataxia by measuring fractional anisotropy (FA) values in diffusion tensor MRIs (DTI). FA and apparent diffusion coefficient (ADC) values were compared in the brain stem and cerebellum of 5 patients with idiopathic cerebellar ataxia-C and 7 age-matched controls. Patients with sporadic cerebellar ataxia had decreased FA values in the bilateral cerebellar peduncle and cerebellar hemisphere, but normal FA values in the basis pontes. Assuming that the loss in FA parallels neuronal changes, our results suggest that the derangement and altered fiber integrity of the cerebellum are present regardless of the presence of morphological alterations on conventional MRI. Therefore, DTI may be superior to conventional MRI in the evaluation of early pathological changes in patients with sporadic cerebellar ataxia.
