目的 :脑梗死患者的智能状况及听觉P3 0 0 指标的变化及其相互关系。方法 :病例组 76例 ,采用听觉刺激检测P3 0 0 ,用韦氏成人智力量表测定智商。对照组 3 8例。结果 :病例组P3 0 0 潜伏期异常率 40 8% ,总智商异常率 (<90分 ) 46 9% ,两者符合率 75 0 %。P3 0 0 潜伏期与操作智商显著相关 (γ =-0 3 3 2 ,P <0 0 1)。P3 0 0 潜伏期对总智商正确确定的敏感性为 66 7% ,特异性为 82 5 %。结论 :P3 0 0 是评价脑梗死患者智能障碍的一个较敏感指标 ,尤其是P3 0 0 潜伏期
Objective: The changes of intelligence status and auditory P3 0 0 indexes in patients with cerebral infarction and their correlation. Methods: Sixty-six cases were enrolled in this study. P3 0 0 was detected by auditory stimulation and IQ was measured by Webster’s Adult Intelligence Scale. Control group 38 cases. Results: The abnormal rate of P3 0 0 in the case group was 40 8%, the total abnormal rate of intelligence (<90 points) was 46 9%, and the coincidence rate was 75 0%. There was a significant correlation between P3 0 0 latency and operative IQ (γ = -0.332, P <0.01). The sensitivities of P3 0 0 to the correct determination of total IQ were 66.7% and specificity of 82.5%. Conclusions: P3 0 0 is a more sensitive indicator for assessing mental retardation in patients with cerebral infarction, especially P3 0 0 latency
