Cognitive as Well as Functional Deficits in Individuals with COVID-19 Infection: A Review
Background: Given instances of 'Extended COVID' symptoms extending into to the persistent phase and case studies demonstrating brain dysfunction in severely afflicted people, there is rising worry regarding the potential cognitive repercussions of COVID-19. However, nothing is known about the type and general occurrence of cognitive difficulties following infection, or about the whole range of illness severity. It is uncertain if cognitive symptoms are connected with the severity of a new coronavirus (COVID-19) illness. Clinical studies have indicated neurological issues in COVID-19 individuals who have been significantly afflicted. However, nothing is known about the nature and overall prevalence of cognitive difficulties following illness, or the whole range of severity. Early identification of neurocognitive symptoms may reduce the likelihood of permanent damage and continued neurocognitive deterioration. The present COVID outbreak is unprecedented in terms of spread and intensity in human society. The consequences for cognitive performance might be just as catastrophic. Although the current focus is on immediate illness treatment, in the near future, attention will need to shift to the lengthy consequences of COVID infection and how to decrease them. When age, gender, educational status, wealth, race of people, and well before medical conditions were all controlled for, people who had cured displayed severe cognitive abnormalities. They exhibited a significant impact size not just for patients who were institutionalized, but also for moderate yet medically proven instances with no breathing trouble. Performance assessments at a higher level back up the concept that COVID-19 has a multi-system influence on human intelligence.
Aim: The purpose of this study is to analyse the real outline of cognitive and functional impairment found in COVID by examining all published case studies and publications to create a thorough evaluation.
Methods: Search strategy we searched Google scholar, Scopus, Research gate, Medline, PubMed and WHO sites to understand and throw light on the cognitive manifestations of novel coronavirus disease to prepare a review. We limited our search to relevant English language publications from recent years. For MEDLINE the search terms used were COVID-19, delirium, neurological manifestations, cognitive impairment and found numerous articles related to the topic. References from linked reviews and collected papers were also reviewed for potentially relevant literature.
