Perioperative Assessment of Cerebellar Masses and the Potential for Cerebellar Cognitive Affective Syndrome.
The cerebellum was long perceived to be a region of limited importance with primary functions in the regulation of motor control. A degree of its functional topography in motor modulation has been traditionally appreciated. However, an evolving body of evidence supports its role in a range of cognitive processes, including executive decision making, language, emotional processing, and working memory. To this end, numerous studies of cerebellar stroke syndromes as well as investigations with functional magnetic resonance imaging and diffusion tensor imaging have given clinicians a better model of the functional topography within the cerebellum and the essential lanes of communication with the cerebrum. With this deeper understanding, neurosurgeons should integrate these domains into the perioperative evaluation and postoperative rehabilitation of patients with cerebellar tumors. This review aims to discuss these understandings and identify valuable tools for implementation into clinical practice.
