From 2019 to 2023, the global population experienced a period characterized by the outbreak of the coronavirus pandemic, which was attributed to the SARS-CoV-2 virus. Cognitive impairment, particularly memory loss, is frequently reported by individuals who have recovered from Covid-19, alongside other neurological symptoms. This phenomenon not only carries implications for individual health, but also extends to social and economic domains. This phenomenon garners the interest of scholars. Numerous empirical investigations have established a correlation between the COVID-19 pandemic and mental health disorders. The infection caused by SARS-CoV-2 has been associated with the manifestation of psychiatric symptoms. Additionally, individuals with pre-existing mental illness are more susceptible to experiencing more severe outcomes of COVID-19, increased mortality rates, and enduring residual symptoms over an extended period of time.
Dementia itself encompasses a multitude of risk factors, including but not limited to advanced age, vascular and metabolic disorders, obesity, hypodynamic lifestyle, various infections, depression, smoking and social isolation. These factors should be considered collectively when evaluating cognitive impairment following COVID-19 infection.
Nevertheless, it is obvious that COVID-19 survivors frequently experience health concerns related to memory, attention, perception, and other cognitive domains, necessitating thorough assessment and, in certain cases, intervention.
Given the frequency of “memory decline” in the post-Covid period, especially in young and middle age, it is evident that cognitive dysfunction caused by COVID-19 impairment can have detrimental effects on both quality of life and the ability to perform daily tasks efficiently.
In summary, the existing literature review indicates a lack of comprehensive understanding regarding the impact of COVID-19 on cognitive impairment. Consequently, there is a pressing need for further research endeavors that are more focused and specific in nature.
