Impacts on cognition of older adults infected by COVID-19: a literature review
Keywords:Aged, aging, cognition, COVID-19
One of the sequelae of COVID-19 infection is cognitive deficits. The older population is characterized as a high-risk group, making it important to determine the cognitive impacts of the disease in this group. The aim of the present study was to identify the impacts on cognition in older survivors of COVID-19. An integrative literature review was carried out in May 2022. The search was conducted in PubMed, Scopus, Web of Science and BIREME databases, using the following descriptors: “cognition”, “COVID-19”, “older adults” and “aging”. The search yielded 1.958 potentially relevant titles. After excluding duplicates and applying the exclusion criteria to the title and abstracts of the articles selected, 44 studies were read in full, with five included in the final review. The results showed that older survivors of COVID-19 had cognitive deficits ranging from mild to severe impairment. The predominant cognitive impacts in this population were memory functions, verbal functioning, encoding and executive functions. These cognitive impairments affect daily activities of older survivors of COVID-19, highlighting the need for actions to prevent the disease in this population.
