The ongoing pandemic of Coronavirus disease 2019 (COVID-19) has infected more than 27 million confirmed cases and 8,90,000 deaths all around the world. Verity of viral infections can infect the nervous system; these viral infections can present a wide range of manifestation. The aim of the current study was to systematically review the COVID-19 associated central nervous system manifestations, mental and neurological symptoms. For that we conducted a comprehensive systematic literature review of four online databases, including Web of Science, PubMed, Scopus and Embase. All relevant articles that reported psychiatric/psychological symptoms or disorders in COVID-19 without considering time and language restrictions were assessed. All the study procedures were performed based on the PRISMA criteria. Due to the screening, 14 studies were included. The current study result indicated that, the pooled prevalence of CNS or mental associated disorders with 95% CI was 50.68% (6.68-93.88). The most prevalence symptoms were hyposmia/anosmia/olfactory dysfunction (number of study: 10) with 36.20% (14.99-60.51). Only one study reported numbness/paresthesia and dysphonia. Pooled prevalence of numbness/paresthesia and dysphonia was 5.83% (2.17-12.25) and 2.39% (10.75-14.22). The pooled prevalence of depression and anxiety was 3.52% (2.62-4.54) and 13.92% (9.44-19.08). Our findings demonstrate that COVID-19 has a certain relation with neurological symptoms. The hypsomia, anosmia or olfactory dysfunction was most frequent symptom. Other symptoms were headache or dizziness, dysgeusia or ageusia, dysphonia and fatigue. Depression, anxiety, and confusion were less frequent symptoms.
目前的研究旨在系统回顾与 COVID-19 相关的中枢神经系统表现、精神和神经症状。为此,我们对包括 Web of Science、PubMed、Scopus 和 Embase 在内的四个在线数据库进行了全面的系统文献综述。评估了所有报告 COVID-19 患者出现精神病学/心理学症状或障碍的相关文章,未考虑时间和语言限制。所有研究程序均按照 PRISMA 标准进行。由于筛选,共纳入 14 项研究。本研究结果表明,合并的 CNS 或精神相关疾病的患病率为 95%CI 的 50.68%(6.68-93.88)。最常见的症状是嗅觉减退/丧失/嗅觉障碍(研究数量:10),患病率为 36.20%(14.99-60.51)。只有一项研究报告了麻木/感觉异常和发音困难。麻木/感觉异常和发音困难的合并患病率为 5.83%(2.17-12.25)和 2.39%(10.75-14.22)。抑郁和焦虑的合并患病率为 3.52%(2.62-4.54)和 13.92%(9.44-19.08)。我们的研究结果表明,COVID-19 与神经系统症状有一定关系。嗅觉减退、嗅觉丧失或嗅觉障碍是最常见的症状。其他症状包括头痛或头晕、味觉障碍或味觉丧失、发音困难和疲劳。抑郁、焦虑和意识模糊是不太常见的症状。
