Covid-19 and Children's Social Development Changes in cognitive functioning after COVID-19: A systematic review and meta-analysis

ABSTRACT

Summary In this chapter, the authors focus on disruptions to children's lives at home and at school (including early childhood care and education programs [ECCE] and primary schooling) as critical settings for healthy development. The Covid-19 pandemic has upended children's lives in myriad ways, including disruptions in the family system due to illness or death, financial instability tied to job loss, and educational disruptions as a result of closures of child care facilities and schools. In considering how the Covid-19 pandemic is shaping children's social development, the authors attend to how interactions with others and socialization processes within families and schools may buffer or exacerbate the pandemic's negative impact. Developmental scientists are well positioned to research how macro-level shocks such as the coronavirus pandemic affect children's developmental trajectories, and the life-course perspective can guide and inform that investigation. Introduction We conducted a systematic review and meta-analysis of the cognitive effects of coronavirus disease 2019 (COVID-19) in adults with no prior history of cognitive impairment. Methods Searches in Medline/Web of Science/Embase from January 1, 2020, to December 13, 2021, were performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.  A meta-analysis of the Montreal Cognitive Assessment (MoCA) total score comparing recovered COVID-19 and healthy controls was performed. Results Oof 6202 articles, 27 studies with 2049 individuals were included (mean age = 56.05 years, evaluation time ranged from the acute phase to 7 months post-infection). Impairment in executive functions, attention, and memory were found in post-COVID-19 patients.  The meta-analysis was performed with a subgroup of 290 individuals and showed a difference in MoCA score between post-COVID-19 patients versus controls (mean difference = ?0.94, 95% confidence interval [CI] ?1.59, ?0.29;P = .0049). Discussion Patients recovered from COVID-19 have lower general cognition compared to healthy controls up to 7 months post-infection.
