目的 (1)探讨短暂性脑缺血发作(transient ischemic attacks,TIAs)患者在临床症状消失后是否遗留智力障碍;(2)明确颈内动脉系统TIAs与椎一基底动脉系统TIAs患者智力改变的异同。方法 对34例TIAs患者(其中颈内动脉系统TIAs和椎一基底动脉系统TIAs各17例)和34例对照分别进行修订韦氏成人智力量表检测。结果 (1)TIAs患者的各项量表评分均明显低于对照组(除图形拼凑项的P值小于0.05外,其余各项的P值均小于0.01);(2)除椎-基底动脉系统TIAs患者图片排列项的等值量表分明显低于颈内动脉系统TIAs外(P<0.05),其余各项评分两组无显著性差异(P>0.05)。结论 (1)TIAs患者在症状消失后可能依旧存在不同程度的智力障碍;(2)椎-基底动脉系统TIAs患者的智力(主要是理解能力)损害可能比颈内动脉系统TIAs患者更加严重。
Objectives (1) To investigate whether there is mental retardation in patients with transient ischemic attacks (TIAs) after the clinical symptoms disappear; (2) to clarify the similarities and differences in mental changes between TIAs in the internal carotid artery system and TIAs in the vertebrobasilar artery system . Methods 34 cases of TIAs patients (including TIAs in internal carotid artery system and 17 cases of TIAs in vertebrobasilar artery system) and 34 controls were tested by Wechsler Adult Intelligence Scale. Results (1) All scores of TIAs patients were significantly lower than those of the control group (P values were less than 0.01 except P <0.05 in graphic patchwork); (2) In addition to vertebrobasilar artery system The equivalent scales of the pictures of TIAs patients were significantly lower than that of TIAs of the internal carotid artery system (P <0.05). There was no significant difference between the two groups (P> 0.05). Conclusions (1) TIAs patients may still have some degree of mental retardation after symptom disappears. (2) Intelligence (mainly comprehension ability) damage in TIAs patients with vertebrobasilar artery system may be more serious than TIAs patients in internal carotid artery system.
