目的:探讨心因性头晕患者的心理学及电生理学特征。方法:确诊为心因性头晕的患者32例与年龄、性别匹配的健康人50例和器质性头晕36例做对照,进行焦虑自评量表(SAS)、抑郁自评量表(SDS)测定、重心摇动图和定量脑电图检查。结果:心因性头晕组的(SAS和SDS)得分明显高于正常对照组(P<0.05);和正常对照组间重心摇动图无统计学差异(P>0.05);与器质性头晕组有显著差异(P<0.05);定量脑电图检查(qEEG)结果发现α节律活动的显著减少和快波频带的左右不对称性(P<0.01)。结论:心因性头晕患者通常伴有焦虑或抑郁症状;重心摇动图正常;qEEGα节律活动的显著减少和快波频带的左右不对称。
Objective: To investigate the psychological and electrophysiological characteristics of patients with psychogenic dizziness. Methods: Thirty-two patients diagnosed as having dizziness due to dizziness were compared with age-matched and healthy-matched healthy subjects and 36 patients with organic dizziness. The self-rating anxiety scale (SAS), self-rating depression scale (SDS) Determination, center of gravity and quantitative electroencephalogram echocardiography. Results: The score of SAS and SDS in psychogenic dizziness group was significantly higher than that in normal control group (P <0.05). There was no significant difference between the control group and normal control group (P> 0.05) (P <0.05). Quantitative electroencephalogram (qEEG) results showed a significant decrease in α rhythmic activity and left-right asymmetry in the fast wave band (P <0.01). CONCLUSIONS: Patients with cardiogenic dizziness usually have symptoms of anxiety or depressive symptoms; normal barycenter shakings; a significant reduction in qEEGα rhythmic activity and left-right asymmetry in fast wave bands.
