The cognitive and behavioral effects of meningioma lesions involving the ventromedial prefrontal cortex
2016
OBJECT Anterior skull base meningiomas are frequently associated with changes in personality and behavior. Although such meningiomas often damage the ventromedial prefrontal cortex (vmPFC), which is important for higher cognition, the cognitive and behavioral effects of these meningiomas remain poorly understood. Using detailed neuropsychological assessments in a large series of patients, this study examined the cognitive and behavioral effects of meningioma lesions involving the vmPFC. METHODS The authors reviewed neuropsychology and lesion mapping records of 70 patients who underwent resection of meningiomas. The patients were drawn from the Neurological Patient Registry at the University of Iowa. Patients were sorted into 2 groups: those with lesions involving the vmPFC and those with lesions that did not involve the vmPFC. Neuropsychological data pertaining to a comprehensive array of cognitive and behavioral domains were available preoperatively in 20 patients and postoperatively in all 70 patients. ...
