A new study by Teresa Liu and team showed that patient reported cognitive impairments during the first four weeks of SARS-CoV-2 infection are linked to post–COVID-19 condition (PCC) symptoms, and some patients' PCC may also have an emotional component. The findings of this study were published in Journal of American Medical Association.
Acute SARS-CoV-2 infection and post-COVID-19 condition (PCC; also known as extended COVID) both frequently cause neuropsychiatric symptoms, however it is uncertain if these symptoms and PCC are related. In order to better understand the characteristics of patients with observed cognitive impairments within the first four weeks of SARS-CoV-2 infection and the relationship between those deficits and PCC symptoms, this study was carried out.

With a follow-up of 60 to 90 days, this prospective cohort research took place from April 2020 to February 2021. The cohort was made up of adults registered in the University of California, Los Angeles, SARS-CoV-2 Ambulatory Programme who had a laboratory-confirmed symptomatic SARS-CoV-2 infection and were either hospitalized in a UC Los Angeles hospital or one of 20 nearby healthcare facilities, or were outpatients referred by a primary care physician. The period of data analysis was from March 2022 to February 2023.
The key findings of this study were:
At 30 days after hospital discharge or outpatient diagnosis, 766 of the 1296 patients who were included in the programme completed the perceived cognitive impairment items.
276 out of the 766 patients felt they had a cognitive disability, with 112 patients having a mean score over 1.5 and 164 having a mean score between 0 and 1.5.
Reports of a reported cognitive disadvantage were linked to prior cognitive problems and a diagnosis of depressive illness.
Those with reported cognitive abnormalities in the first four weeks after contracting SARS-CoV-2 were more likely to experience PCC symptoms than those without such perceptions.
Perceived cognitive impairments during the first four weeks of SARS-CoV-2 infection were linked to PCC symptoms compared to no perceived cognitive deficits after adjusting for demographic and clinical variables.
