Abstract
Objective
The purpose of this systematic review is to identify neuropsychological sequelae following infection of SARS-CoV-2.
Data Selection
A systematic search of the literature was conducted in 2021 using the keywords: neuropsychological symptoms, neuropsychological sequelae, neuropsychological manifestations, SARS-CoV-2, COVID-19, and coronavirus. The search conducted included a total of 6 databases: PsychNet, ProQuest, Taylor & Francis Online, EBSCOhost, Google Scholar, and PubMed Central. A total number of 25 articles were considered, and 8 of those articles were retained. Inclusion criteria consisted of peer-reviewed articles published in English between the years 2020 and 2021. Exclusion criteria consisted of articles not published in English and those that did not examine the neuropsychological symptoms following COVID-19 infection.
Data Synthesis
Literature examined reported that clinical observations of severe cases of COVID-19 infection were associated with the presence of neuropsychological symptoms. Post-infection of SARS-CoV-2, the following symptoms have been noted: severe executive dysfunction, fluctuations in attention and concentration, and instances of disorientation and confusion. Although etiological hypotheses have been made, there is still no consensus or treatment for the neuropsychological sequelae of COVID-19. Studies also reported that a significant risk factor for these individuals was the presence of premorbid psychological/psychiatric illnesses.
Conclusions
Patients who recover from severe COVID-19 can experience a multitude of neuropsychological manifestations. In some cases, these effects have been reported to be long-standing. Due to limited understanding regarding the nature and mechanism of action of SARS-CoV-2, it is difficult to pinpoint the cause, duration, treatment, and prognosis of neuropsychological symptoms of post-recovery patients.
