A Clinical Study of 16 Patients with Ataxic Hemiparesis

ABSTRACT

A clinical study was carried out in 16 patients with ataxic hemiparesis who were seen at Young Dong Severance Hospital, and following results were obtained. 1. The age of patients ranged from 37 to 80 years (mean 61.6) and there were 10 men and 6 women. 2. The etiologies were infarction (13 patients), hemorrhage (1 patient), tuberculosis (1 patient), and unknown (1 patient). 3. The sites of lesion were pons (8 patients), internal capsule (4 patients), pons and midbrain (2 patients), midbrain (1 patient), and thalamus (1 patient). 4. The symptoms other than ataxic hemiparesis were dysarthria in the lesion of pons, cranial nerve deficits and dysarthria in the lesion of midbrain, and sensory deficits in the lesion of internal capsule. Usually ataxic hemiparesis is known as a classic form of lacunar symdrome. But now, it is known as a only symptom comples, not a disease entity, that comes by any lesion involving both cortico-spinal tract and dentato-rubro-thalamo-cortical pathway or contico-pontine fiber or ponto-cerebellar fiber.
