隐匿抑郁症患者脑电特点分析

Characteristics of electroencephalogram in patients with concealed depression

目的探讨隐匿抑郁症患者的脑电变化特点。方法经神经内科门诊筛查选择86例以躯体化症状为主诉的隐匿抑郁症患者作为观察组,另设65例健康体检者作为正常对照组,两组均行脑电图、脑干听觉诱发电位和视觉诱发电位检查。结果观察组脑电图异常率63.95%,正常对照组异常率仅为13.85%,两组比较有显著性差异(P<0.05)。观察组脑电图以轻度异常为主,局限性异常多见于额叶,诱发电位以各主波及波间潜伏期较正常对照组显著性延长。结论以躯体化障碍为主诉的抑郁症患者其脑电图异常率明显高于正常人,且诱发电位潜伏期延长。

Objective To discuss the characteristics of electroencephalogram in the patients with concealed depression. Mehtod The observation group included 86 patients with somatization symptoms screened from the outpatient department of neurology and the control group included 65 health cases. Two groups were given the examinations respectively of electroencephalogram, brain-stem auditory evoked potential （BAEP） and visual evoked potential （VEP）. Result The abnormality rate of electroencephalogram was 63.95 % in the observation group and 13.85 % in the normal control group. The difference was significant between two groups （P〈0.05）. The electroencephalogram change in the observation group was mainly paranormal. The local abnormity was seen mainly in the frontal lobe. The changes of evoked potential were mainly that the delitescence among various fundamental waves and delitescence between waves were prolonged significantly in the observation group than that in the normal control group. Conclusion The abnormality rate of electroencephalogram in the patients with concealed depression with the presenting symptoms of somatization disorder is higher significantly than that of the normal people, and the delitescence of evoked potential is prolonged.
