Abstract

The impact of the COVID-19 pandemic on people’s lives is dramatic. The relationship between Brain Fog and Long-COVID, the consequences on the mental health of patients, and its treatment are the objectives of this systematic review. An electronic search was carried out and databases searched included PubMed, Emerald, EMBASE, and Science Direct. Regarding the review, data collection included English papers with full bibliographies, abstracts, and keywords, published in electronic form in the last 2 years (2020–2022). The findings indicate the importance of a holistic approach and treatment of Post-COVID Brain Fog. It is also necessary for healthcare workers to investigate the biological and psychosocial background of Brain Fog symptoms in detail to provide the appropriate health service. However, more scientific studies are needed on the effectiveness of treatment approaches for the benefit of public health and well-being.
