冰毒所致精神障碍患者的注意网络功能研究

目的 探讨冰毒所致精神障碍患者注意网络认知功能缺损的特征.方法 对100例冰毒所致精神障碍者入院第1周和入院第4周进行注意网络功能测试(ANT).结果 (1)与对照组相比,冰毒所致精神障碍组第1次ANT的平均反应时明显延长,正确率、定向作用和执行控制功能明显下降[如:平均反应时(867.37±272.24)ms,(668.56±136.20)ms;正确率(0.88±0.06)ms,(0.88±0.06)ms;定向作用(-217.86±198.0)ms,(-59.67±85.07)ms;执行控制功能(184.74±66.61)ms,(74.71±50.77)ms,P＜0.01],而警觉网络功能则明显提高[如(151.17±198.27)ms,(50.60±67.47)ms];(2)第2次ANT成绩与健康对照组差别无显著性意义(P＞0.05).(3)与第1次ANT成绩相比冰毒所致精神障碍组的第2次ANT成绩的平均反应时明显缩短,正确率,定向作用,执行控制功能明显提高(P＜0.01),而警觉网络功能则明显下降(P＞0.05).结论 冰毒所致精神障碍者的注意网络认知功能存在缺陷,此缺陷可在1月内痊愈.

Research about attention network of patients with amphetamine-induced psychiatric disorders

Objective To investigate the characteristics of the cognitive impairment about attentional network among amphetamine-induced psychiatric disorders. Methods Amphetamine-induced psychiatric disorders ( n = 100) and normal controls ( n = 100) were assessed with Attentional Network Test(ANT) in the first week and the fourth week. Results Compared with the control group, the first ANT's response time was significantly increased, and the correct rate, orienting and executive control network were significantly reduced in Amphetamineinduced psychiatric disorders( eg:response time ( 867. 37 ± 272.24 ) ms vs ( 668.56 ± 136. 20 ) ms, correct rate (0.88 ±0.06 ) ms vs (0.88 ±0.06) ms ,orienting( - 217.86 ± 198.00 ) ms vs ( -59.67 ± 85.07 ) ms and executive control network ( 184.74 ± 66.61 ) ms vs ( 74.71 ± 50.77 ) ms, P ＜ 0.01 ), but the alerting network was higher ( ( 151.17 ± 198.27 ) ms vs (50.60 ± 67.47 ) ms). In the second ANT results, there was no significant difference between two groups. Compared with the first ANT results of amphetamine-induced psychiatric disorders, the second ANT had shorten response time ,that the correct rate, orienting and executive control network were significantly increased(P ＜ 0.01 ). Conclusion These results suggest that amphetamine-induced psychiatric disorders have impairment in cognitive function, but these impairment can be recovered within one month.
