目的：探讨中重度闭合性颅脑损伤(CHI)患者的前额叶皮质弥漫性损伤是否会影响对社会相关信息的感知和反应能力。方法：对CHI受试者和年龄匹配的非颅脑损伤对照组分别呈现不同表情的面孔，同时监测其皮肤电活动(EDA)。结果：CHI患者对负面表情的反应不能增加EDA，识别负面表情的能力降低，尤其是恐惧。两组在眼眶/内侧前额叶损伤的其他体征上存在差异，如嗅觉障碍，以及Brock适应性功能问卷测量的一般社会适应性和缺陷意识。结论：CHI影响了对负面面部表情的识别和反应能力。解决这些缺陷可能会加强社会领域内的康复努力。
The objective was to determine whether diffuse damage to orbital and ventromedial regions of the prefrontal cortex usually associated with moderate-to-severe closed head injury (CHI) would affect the ability to perceive and respond to socially relevant information.Methods: Participants with CHI and age-matched non-injured controls were presented with faces that varied with respect to emotional expression while electrodermal activity (EDA) was monitored. Cognitive and general adaptive functioning was also assessed.Results: CHI was associated with a failure to increase EDA in response to negative facial expressions and with reduced ability to identify negative expressions, especially fear. The groups differed on other signs of orbital/medial prefrontal damage such as anosmia and in general social adaptability and awareness-of-deficit as measured by the Brock Adaptive Functioning Questionnaire.Conclusions: CHI affected the ability to identify and respond to negative facial expression. Addressing these deficits may enhance rehabilitative efforts within the social domain.
