男性精神分裂症暴力违法者脑电图临床特点对照研究

A COMPARATIVE STUDY ON THE EEG OF VIOLENT MALE OFFENDERS WITH SCHIZOPHRENIA

目的:研究暴力违法青年精神分裂症患者的脑电图特征。方法:采用脑电记录仪对400例司法鉴定涉嫌暴力违法精神分裂症患者和进行描记,并将结果与非暴力违法精神分裂症患者的结果进行对照。结果:暴力组脑电图异常频度明显高于对照组(P<0.01);暴力组癫痫样放电征在左侧、右侧与双侧的表达频度与对照组比较差异无显著性(P>0.05);癫痫样放电征左侧大脑半球表达频度显著高于右侧(P<0.01);暴力组癫痫样放电征涉及额叶、颞叶、顶叶和枕叶频度,与对照组比较差异无显著性(P>0.05);癫痫样放电征多在颞叶、额叶表达;暴力组癫痫样放电征总体表达频度与对照组比较差异有显著性(P<0.05)。结论:精神分裂症患者的暴力违法行为可能与大脑损害及大脑癫痫样放电征有关,大脑异常放电冲动刺激可能是导致患者暴力违法的重要因素。

Objective： To study the EEG characteristics of violent male offenders with schizophrenia. Methods： The depiction of 400 cases of judicial appraisal suspected illegal violent male schizophrenia patients （the violent group） was conducted by EEG recorder,the result of which was compared with that of the control. Results：The frequency of EEG abnormalities of the violent group was significantly higher than that of the control（P 〈0. 01 ） ; compared with the control, no significant difference（P 〉0. 05）was observed in the expression frequency of epileptiform discharge levy on the left, fight and bilateral; in the violent group, the expression frequency of epileptiform discharge levy on the left cerebral hemisphere was significantly higher than that on the fight side （ P 〈 0. 01 ） ; the epileptiform discharge levy in the violent group involved the frontal, temporal lobe, parietal lobe and occipital lobe, and mostly expressed in the temporal lobe,frontal lobe, and no significant difference was found compared with that of the control（P 〉 0. 05） ; there was no significant difference in the overall expression between the two groups （ P 〈 0. 05 ）. Conclusion： Offense of violence in patients with schizophrenia may be associated with brain damage and brain symptoms related to epileptiform discharges, and abnormal discharge impulses to stimulate the brain may lead to patients with an important factor in violence against the law.
