Announced by WHO in 2020, the global COVID-19 pandemic caused by SARS-CoV-2 has affected many people, leading to serious health consequences. These consequences are observed in the daily lives of infected patients as various dysfunctions and limitations. More and more people are suffering post-COVID-19 complications that interfere with or completely prevent them from working or even functioning independently on a daily basis. The aim of our study was to demonstrate that innovative quantitative electroencephalography (QEEG) can be used to assess cognitive function disorders reported after the COVID-19 pandemic. It is worth noting that no similar study has been conducted to date in a group of pilots. The QEEG method we used is currently one of the basic neurological examinations, enabling easy observation of post-COVID-19 changes in the nervous system. With the innovativeness of this technique, our study shows that the use of quantitative electroencephalography can be a precursor in identifying complications associated with cognitive function disorders after COVID-19. Our study was conducted on twelve 26-year-old pilots. All participants had attended the same flight academy and had contracted SARS-CoV-2 infection. The pilots began to suspect COVID-19 infection when they developed typical symptoms such as loss of smell and taste, respiratory problems, and rapid fatigue. Quantitative electroencephalography (QEEG), which is one of the most innovative forms of diagnostics, was used to diagnose the patients. Comparison of the results between the study and control groups showed significantly higher values of all measurements of alpha, theta, and beta2 waves in the study group. In the case of the sensorimotor rhythm (SMR), the measurement results were significantly higher in the control group compared to the study group. Our study, conducted on pilots who had recovered from COVID-19, showed changes in the amplitudes of brain waves associated with relaxation and concentration. The results confirmed the issues reported by pilots as evidenced by the increased amplitudes of alfa, theta, and beta2 waves. It should be emphasized that the modern diagnostic method (QEEG) presented here has significant importance in the medical diagnosis of various symptoms and observation of treatment effects in individuals who have contracted the SARS-CoV-2 virus. The present study demonstrated an innovative approach to the diagnosis of neurological complications after COVID-19.
世界卫生组织于2020年宣布，由严重急性呼吸综合征冠状病毒2（SARS-CoV-2）引起的全球新冠疫情影响了众多人群，导致了严重的健康后果。这些后果在感染患者的日常生活中表现为各种功能障碍和限制。越来越多的人正遭受新冠后遗症的折磨，这些后遗症干扰甚至完全阻碍他们日常工作，甚至独立生活。我们研究的目的是证明创新型定量脑电图（QEEG）可用于评估新冠疫情后报告的认知功能障碍。值得注意的是，迄今为止尚未在一组飞行员中进行过类似研究。我们使用的QEEG方法是目前基本的神经学检查方法之一，能够轻松观察新冠后神经系统的变化。鉴于这项技术的创新性，我们的研究表明，使用定量脑电图可以作为识别新冠后与认知功能障碍相关并发症的先导。我们的研究针对12名26岁的飞行员展开。所有参与者都毕业于同一所飞行学院，且都感染过SARS-CoV-2病毒。当飞行员出现嗅觉和味觉丧失、呼吸问题以及快速疲劳等典型症状时，他们开始怀疑感染了新冠病毒。采用最具创新性的诊断形式之一——定量脑电图（QEEG）对患者进行诊断。研究组与对照组结果比较显示，研究组中α波、θ波和β2波的所有测量值均显著更高。在感觉运动节律（SMR）方面，对照组的测量结果相比研究组显著更高。我们对从新冠中康复的飞行员进行的研究显示，与放松和专注相关的脑电波振幅出现了变化。结果证实了飞行员报告的问题，α波、θ波和β2波振幅增加即为证据。应当强调的是，这里介绍的现代诊断方法（QEEG）在对感染SARS-CoV-2病毒个体的各种症状进行医学诊断以及观察治疗效果方面具有重要意义。本研究展示了一种诊断新冠后神经并发症的创新方法。
