PYRAMIDAL TRACT WALLERIAN DEGENERATION AND CORRELATED SYMPTOMS IN STROKE

In order to reveal the precise degree of injury in the pyramidal tract after stroke, we studied 35 patients with motor deficit associated wi th cerebrovascular disease of the internal capsule using the T2-weight ed coronal image along the 'pyramidal line'. According to the severity of the motor deficit, the patients were divided into three groups. Th e Wallerian index was calculated as: (area of Wallerian degeneration i n the pons divided by area of the ipsilateral half of the pons) x 100. There were significant differences between the three groups. It is co ncluded that the area of Wallerian degeneration is related to the seve rity of motor deficit.
