Mental fatigue, brain fog, epídemiology, prognosis, mental confusion, treatment, COVID-19Abstract
Introduction: Studies are indicating a high incidence of acute psychiatric symptoms post SARS-CoV-2 infection. Those who experience persistent symptoms and/or prolonged organic dysfunctions after the acute phase of COVID-19 are diagnosed with post-covid syndrome. Cognitive impairment in this syndrome includes short-term memory deficits, difficulties with concentration and execution and slower thinking compared to the previous pattern of functioning. Objective: To provide an overview of the topic of “Brain Fog” and, in this way, contribute to the knowledge of health professionals and the development of mental health management strategies. Method: This is narrative review of literature, with data collection carried out in the PubMed, LILACS and Scielo databases. 14 papers were selected, which covered the following items on the topic: epidemiology, clinic, prognosis and treatment. Results: Female gender was observed to be associated with a greater chance of presenting post-covid cognitive impairment. Treatment strategies include neuropsychological assessment, cognitive rehabilitation, mental health support and adequate sleep. A multidisciplinary approach is crucial in managing persistent symptoms and supporting the return to normal life. Conclusion: A high prevalence of cognitive dysfunction was observed in the post-acute period of COVID-19 infection. There was also great heterogeneity in the characterization of symptoms, making it necessary to establish consensual definitions about the condition studied, for better investigation of prevention and treatment strategies.
