Clinical study of the responsible lesion for dysarthria in the cerebellum.
There have been few reports describing the lesion for cerebellar dysarthria. We compared MRI findings of 4 reported patients (including our previously reported patient) to that of our patient who showed ataxic speech and ataxic gait. The lesions of 4 patients involved lobulus quadrangularis and lobulus simplex, and the lesion of the present patient involved lobulus semilunaris superior and lobulus simplex. Since lobulus simplex and lobulus quadrangularis were involved in many patients, we speculated that the cerebellar dysarthria of the present patient was due to the damage of these areas in the upper cerebellum.
