The Covid-19 pandemic caused by SARS-CoV-2, emerged in Wuhan, China, between December 2019 and January 2020. At the time of writing this paper, it still represents a significant issue for global health and economics, as well as for livelihood and for physical and mental well-being of people worldwide. A range of persistent symptoms can linger long after the acute infection as a part of a condition called Post-Covid-19 Syndrome or Long Covid. Long Covid can affect many organs and systems including the brain, causing headache, memory and concentration issues, sleep disorders, anxiety and depression. Prevalence, type, and severity of such long-lasting effects and how they may link to other factors such as the severity of initial disease and comorbidities, is still unclear.
