Introduction:
The emergence of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has brought with it a plethora of new challenges. In the beginning of the pandemic, efforts were focused on pathogenesis and acute treatment; however, over time, understanding and managing post-COVID sequelae have become the new frontier.1, 2 Generally, the majority of individuals show symptom resolution within 3–4 weeks of COVID-19, but a substantial number of people continue to experience lingering effects and develop protracted illness, regardless of initial symptom severity. Although still being defined, these effects can be collectively referred to as postacute sequelae of SARS-CoV-2 infection (PASC),3 which is the term used in this report. Notably, there are a number of other terms that are found in the literature (eg, long COVID, postacute COVID-19 syndrome, long-haul COVID, chronic COVID). At the time of development, much of the literature focused on patients who were not vaccinated, and the incidence and trajectory of PASC in vaccinated patients with “breakthrough” cases (including but not limited to current and emerging variants of the virus) are evolving. The PASC Collaborative took this into account during the development process and these guidance statements generally apply to individuals who develop PASC regardless of their vaccination status.
This guidance statement has a specific focus on the cognitive-related symptoms of PASC that can occur in people who have been diagnosed with acute COVID-19 infection or presumed to have had the infection and initially experienced mild to severe symptoms. Some patients required hospital acute care, whereas many others were managed in nonhospitalized community settings. This consensus guidance statement is one in a series extending across the breadth of the most prevalent or recognized PASC sequelae. Published and in-process guidance statements from this collaborative include the assessment and management of PASC associated fatigue, breathing and respiratory sequelae, cardiovascular complications, autonomic dysfunction, mental health, and neurologic sequelae. These statements are intended to provide consensus-driven practice guidance to clinicians in the assessment and treatment of individuals presenting with PASC.
