[Semeiologic aspects of circumscribed thalamic lesions. Clinico-tomodensitometric study].

Abstract

The classical thalamic syndrome of Dejerine and Roussy is very rare. Sensory disorder are almost constant but the thalamic hyperpathia had not been reported. Clinical findings are reported in 14 patients with restricted lesions of the thalamus visible with the CT scan. Occasionally aphasia was found in patients with left sided lesion (with Thalamic Neglect, apraxia, mainly of ideomotor type and the so-called "Central Dazzle"). Thalamic lesions can produce a great variability of signs and symptoms.
