迟缓认知克里思速度（SCT）是指一种临床结构，包括几种症状，如迟缓，心不在焉，低能量。在本研究中，我们比较了有或没有SCT的ADHD儿童的神经认知实验室结果。方法：采用中枢神经系统生命体征成套测验（CNS Vital Signs Battery）测定受试者的神经认知功能。SCT + ADHD组包括42例受试者，ADHD组为41例受试者，对照组为24例受试者。结果：与ADHD儿童相比，ADHD合并SCT儿童的认知灵活性评分受损更严重。此外，SCT + ADHD组在转移注意力测试（p = 0.014）和持续表现测试（反应时间评分，p < 0.01）方面的缺陷大于ADHD组。SCT患者的加工速度、视觉/听觉记忆、心理速度和反应时间并没有受到更大的损害。结论：认知灵活性的损伤，更具体地说，转移注意力和连续的性能可能是警惕性和定向问题，而不是执行功能的SCT结构的指示。
Sluggish Cognitive Tempo (SCT) refers to a clinical construct including several symptoms such as sluggishness, absentmindedness, low energy. In the present study, we compared neurocognitive laboratory outcomes of ADHD children with or without SCT. Method: The CNS Vital Signs Battery was utilized to measure neurocognitive measure of the participants. The SCT + ADHD group comprised of 42 subjects, ADHD group was 41 subjects and control group was 24 subjects. Results: The cognitive flexibility score was found to be more severely impaired in ADHD children with SCT in comparison to the ADHD-only. Additionally, greater deficits in the Shifting Attention Test (p = 0.014) and the Continuous Performance Test (reaction time score, p < 0.01) were found in the SCT + ADHD group relative to ADHD group. Processing speed, visual/auditory memory, psychomotor speed and reaction time were not found to more impaired in those comorbid with SCT. Conclusion: Impairments in the cognitive flexibility and more specifically shifting attention and continuous performance may be indicative of vigilance and orientation problems rather than executive functions for the SCT construct.
