经颅多普勒超声对脑血管状态与人格特征相关性研究

Correlativity Analysis of Cerebrovascular Status which Diagnosed by Using Trancranial Doppler Sonography and the Personality

目的:研究脑血管状态与人格特征的相关性。方法:人格特征应用A型行为类型量表、艾森克人格问卷(EPQ)对60名20-35岁青年人群进行问卷调查,并划分出不同类型;脑血管状态应用经颅多普勒超声(TCD)的诊断技术测查60人的大脑中动脉(MCV)的血流速度来判断脑血管的紧张程度。结果:脑血管紧张组:A型人格为19人占59.3%,对照组:A型人格为3人占10.7%,以A型人格占优势(x2=22.85,P<0.01)。脑血管紧张组(36.2±5.8)A型行为问卷平均得分高于对照组(20.3±2.4))(t=6.81,P<0.01)。脑血管紧张组P分、N分、L分与正常对照组比较,差异无统计学意义(均P>0.05);脑血管紧张组E分(内外向)高于对照组,差异有统计学意义(P<0.05)。四种性格类型相比,外向情绪不稳定型的脑血管紧张组13(40.6%)与对照组4(14.3%)相比所占比例较高(x2=21.91,P<0.05)。结论:A型人格,外向不稳定的人格特征与脑血流速度增快有关,可能是脑血管紧张的诱发因素之一。

Objective： To study the Correlativity analysis of Cerebrovascular status and personality. Methods： A ＂type A behavior questionnaire＂ survey and Eysenck Personality Questionnaire （EPQ） test were conducted among 60 yotmg people who aged 20-35 and then sum up different personality types; Cerebrovascular status by using TCD to exam the MCA blood flow velocity. Statistical analysis was applied to study the correlativity between four kinds of EPQ personality characteristics with cerebral vascular tension, and then to analysis the susceptibility groups of the disease. Results： The type-A behavior rate was 59.3% among the people with Cerebral vascular tone （19/32） and 10.7% among the control （3/28）. The type-A behavior rates in the Cerebral vascular tone people were significantly high- er than that in the controls （xZ=-22.85, P〈0.01 ）.The average ＂type A behavior questionnaire＂ scores of the Cerebral vascular tone group （36.2＋ 5.8 ）were significantly higher than that of the control group （20.3＋ 2.4）（t=-6.81, P〈0.01 ）. Compared with personality traits of the control group, scores of E-dimension significantly increased in the Cerebral vascular tone group （P〈0.05）, but scores of P-dimension, N-dimension and L-dimension had no statistically significant. Comparison of the four kinds of character types indicated that Cerebral vas- cular tone group showed a high proportion （xZ=-21.91, P〈0.05）. Conclusions： Type A behavior pattern and extroversion emotional lability type are positively correlated with cerebral blood flow increase and may be one of the pathogenic factors of cerebral vascular tone.
