✓ Mutism is defined as a state in which a patient is conscious but unwilling or unable to speak. It has been reported to occur in association with a multitude of conditions, including trauma, epilepsy, tumors, stroke, psychoses, and brain surgery. The cases of two patients who became mute in the immediate postoperative period are presented. The first patient developed mutism following removal of a parasagittal meningioma, and the second following removal of a posterior fossa medulloblastoma. It is believed that transient injury may have occurred to the supplementary motor cortex in the first case and to the dentate nuclei in the second case. It is interesting that these two areas are connected via pathways involving the ventrolateral nucleus of the thalamus, and that lesions of this thalamic nucleus can also lead to mutism. It therefore appears plausible that interruption of these pathways may be involved in the pathogenesis of mutism. Although mutism is an infrequent complication of brain surgery, neurosurgeons should be aware that it may occur following removal of lesions in these areas and that it is generally a transient condition.

The beneficial clinical effects of stereotactic lesions in the ventrolateral nucleus of the thalamus in the treatment of Parkinsonism are well established. Studies of the cognitive and personality changes, however, have given contradictory results. This may be due to the great variety of tests used, to lack of control groups and to the fact that some investigators have studied only unilateral operations, whereas others have included some patients operated on bilaterally. Changes, presumably permanent, have been reported in intelligence (Jurko and Andy, 1961; Lenshoek and Manem, 1960; Niehbuhr, 1962; Jurko and Andy, 1964); concept formation (Jurko and Andy, 1961); extraversion (Fortin, 1960; Jurko and Andy, 1961); and anxiety (Niehbuhr, 1962). Transient changes have been reported in intelligence (Riklan, 1961; Levita et al., 1964); human figure drawing (Riklan et al., 1962); integrity of personality (Fortin et al., 1961; Fortin, 1960; Riklan, 1961); and somatosensory status (Proctor et al., 1963). In other studies no change was found following the operation (Bravo and Cooper, 1959; Gillingham et al., 1960; Gillingham et al., 1964; Levita and Riklan, 1965; Muller and Yasargil, 1959; Riklan, 1962).
