![]() ![]() However, patients with left temporal lobe epilepsy (LTLE) frequently have impaired verbal memory preoperatively. Previous studies have shown that left temporal lobectomy for intractable epilepsy can lead to verbal memory deficits. In the future, neuropsychological examinations of social cognition, in addition to those of global intelligence, memory, and verbal function, will contribute to the provision of comprehensive medical care to patients with epilepsy.Ĭognitive consequences of two-thirds anterior temporal lobectomy on verbal memory in 144 patients: a three-month follow-up study. Early-onset right mesial temporal lobe epilepsy with hippocampal sclerosis is the key substrate determining a severe deficit in recognizing emotional facial expressions and decision-making. Studies on social cognitive functions in mesial temporal lobe epilepsy are being pursued currently. Findings of research on neural mechanisms underlying social cognitive functions have emphasized the roles of the cerebral limbic system, such as the amygdalo-hippocampal complexes, and the emotional system in the ventromedial prefrontal area. These functions mainly involve facial expression recognition and decision-making. This cognitive function, proposed by Brothers in 1990, is a collective term for functions needed in social life these include functions required to interpret the expressions, feelings, and intentions of others and to form and maintain smooth human relationships while making decisions necessary for self-survival. However, the concept of social cognitive function has been recently proposed in the field of neuropsychology. Thus far, research on cognitive functions related to temporal lobe epilepsy has focused on memory, language, and general intelligence. Furthermore, assessments of the cognitive functions of patients with epilepsy using various tests aid in providing comprehensive medical care. The importance of neuropsychological examinations in epilepsy care and, especially, in epilepsy surgery is centered on the following roles: they offer a means to confirm the epileptic focus by multi-modal preoperative assessments and they help to assess postoperative functional changes based on preoperative cognitive functions.
