Abstract: | Since the age of three years the patient suffered from early drug-resistant partial epilepsy with electric status during slow sleep, owing to a micropolygyric malformation of the right fronto-temporo-parietal lobes. The hemispherotomy (when five years of age) was followed by immediate and persistent disappearance of the seizures and withdrawal of the treatment. The transfer of right hemispheric functions to the left hemisphere occurred very early; the child’s development was examined in relation to the restoration of these functions and the age at surgery. The early surgical intervention and the plasticity of the brain – along with an intensive cognitive rehabilitation – seem to be important in determining the favorable global cognitive outcome. Visuo-spatial abilities and multi-modal integration of these functions with memory, attention and language have been the most critical domains and are recently in progress. The rapidity of processing complex tasks is particularly lacking. This seems to be the expression of the defective development of the Central Executive System. |
