摘要:

失匹配负波是不受意识支配自发产生的,是脑创伤患者的神经完整性受损和功能异常的早期监测指标,而且不受精神药物的影响,失匹配负波缺陷会导致认知功能下降。为探索脑创伤患者失匹配负波与神经认知和日常生活、社会功能预后的相关性,收集12例脑创伤患者与12例正常健康对照者,应用成人韦氏智力量表对其进行神经认知检测、应用日常生活活动能力量表和社会功能缺陷筛选量表对日常生活社会功能进行检测,以及脑电图记录检测失匹配负波。结果发现,与正常健康对照者相比,脑创伤组的失匹配负波波幅降低,失匹配负波与神经认知呈负相关,和功能预后呈正相关,且以额中央区失匹配负波与功能预后正相关性最大;FCz电极的失匹配负波与日常生活功能正相关性最大;Fz电极的失匹配负波波幅与社会功能正相关性最大。结果说明,失匹配负波能高效反映脑创伤患者的功能预后情况。

Abstract:

Mismatch negativity is generated automatically, and is an early monitoring indicator of neuronal integrity impairment and functional abnormality in patients with brain injury, leading to decline of cognitive function. Antipsychotic medication cannot affect mismatch negativity. The present study aimed to explore the relationships of mismatch negativity with neurocognition, daily life and social functional outcomes in patients after brain injury. Twelve patients with traumatic brain injury and 12 healthy controls were recruited in this study. We examined neurocognition with the Wechsler Adult Intelligence Scale-Revised China, and daily and social functional outcomes with the Activity of Daily Living Scale and Social Disability Screening Schedule, respectively. Mismatch negativity was analyzed from electroencephalogram recording. The results showed that mismatch negativity amplitudes decreased in patients with traumatic brain injury compared with healthy controls. Mismatch negativity amplitude was negatively correlated with measurements of neurocognition and positively correlated with functional outcomes in patients after traumatic brain injury. Further, the most significant positive correlations were found between mismatch negativity in the fronto-central region and measures of functional outcomes. The most significant positive correlations were also found between mismatch negativity at the FCz electrode and daily living function. Mismatch negativity amplitudes were extremely positively associated with Social Disability Screening Schedule scores at the Fz electrode in brain injury patients. These experimental findings suggest that mismatch negativity might efficiently reflect functional outcomes in patients after traumatic brain injury.
