[Changes in functional cerebral laterality of patients with torticollis spasmodicus]

By comparing the results of tapping with and without simultaneous speaking and by evaluating their lateral differences the probable lateralization of functional speech centre was established in 28 patients with torticollis spasmodicus and 28 healthy controls. In doing this, it became evident that unlike the controls the patients as a hole in a significant way lateralized the speech centre more frequently to the right. The changed cerebral laterality in the patients was supposed to be stimulated by pronounced emotional conflicts and to be involved in the disease of torticollis spasmodicus.
