精神分裂症患者的执行功能障碍是最严重的认知功能障碍，与神经活动异常有关，尤其是额叶。基于非线性动力学和任务执行测试的脑电图（EEG）记录复杂性估计已被广泛用于估计精神分裂症患者的执行功能障碍。MethodsThe fractal dimension（FD）values based on the fractal dimension values of EEG data recorded from first episode schizophrenia patients and healthy controlled controlled control during the performance of three cool executive functions task，结果首次发作精神分裂症患者在执行功能操作过程中，采用FD方法测量的额叶脑电信号的复杂性不同。然而，没有发现患者和对照组之间的差异，在FD值的EEG数据，记录在性能的塔的河内task.ConclusionsThese结果表明，冷静的执行功能表现出很少的损害首发精神分裂症患者。
BackgroundIn schizophrenia, executive dysfunction is the most critical cognitive impairment, and is associated with abnormal neural activities, especially in the frontal lobes. Complexity estimation using electroencephalogram (EEG) recording based on nonlinear dynamics and task performance tests have been widely used to estimate executive dysfunction in schizophrenia.MethodsThe present study estimated the cool executive function based on fractal dimension (FD) values of EEG data recorded from first-episode schizophrenia patients and healthy controls during the performance of three cool executive function tasks, namely, the Trail Making Test-A (TMT-A), Trail Making Test-B (TMT-B), and Tower of Hanoi tasks.ResultsThe results show that the complexity of the frontal EEG signals that were measured using FD was different in first-episode schizophrenia patients during the manipulation of executive function. However, no differences between patients and controls were found in the FD values of the EEG data that was recorded during the performance of the Tower of Hanoi task.ConclusionsThese results suggest that cool executive function exhibits little impairment in first-episode schizophrenia patients.
