ABSTRACT
OBJECTIVE: Long COVID is characterized by persistent symptoms following a COVID-19 infection, including cognitive and emotional impairment. Brazil has one of the highest rates of COVID-19 infections globally, but there are still few studies assessing the long-term impact of the disease on mental health in this population. In the present study, we evaluated cognition and emotional symptoms in patients with cognitive complaints after COVID infection in Rio de Janeiro, Brazil.
METHOD: Cognitive and emotional assessments were performed individually (n = 114) using the Cognitive Screening (TRIACOG) and the Depression, Anxiety, and Stress Scale-21 (DASS-21) in participants with long COVID. Of the total subjects, 78% were women, with a mean age of 50.4 ± 16 years. A total of 72.6% received treatment at home, whereas 28% were hospitalized during the acute phase of the infection.
RESULTS: Our data revealed a high prevalence of cognitive and emotional impairment. Approximately 66.7% exhibited symptoms suggestive of depression, 55.9% anxiety disorder, and 65.7% stress. Notably, executive functions and memory were the most affected cognitive domains. Intriguingly, the time from infection onset to assessment did not appear to influence cognitive performance, suggesting that cognitive impairment associated with COVID-19 may persist as a long-term comorbidity. Furthermore, hospitalization did not affect cognitive or DASS-21 scores.
CONCLUSIONS: These findings underscore the importance of investigating the long-term impacts of COVID-19 on mental health. Assessing emotional and cognitive functions after COVID-19 is crucial for developing therapeutic responses, both on an individual level and from a public health perspective.
