Post-COVID-19 Cognitive Impairment: A systematic Review of Prevalence, Affected Domains and Underlying Mechanisms Snigdha Sahai* Snigdha Sahai Sahai University of Alabama at Birmingham
Long-term cognitive consequences of COVID-19 have emerged as a critical public health concern in recent times. An increasing body of evidence indicates that individuals recovering from the SARS-CoV-2 infection frequently experience “brain fog” scientifically referred as cognitive impairments. These impairments consequently affect memory, attention, execution of decisions and processing speed, significantly affecting the quality of life and functional outcomes (Gwenaëlle Douaud et al., 2022). Therefore, understanding the prevalence, persistence and underlying mechanisms of post-COVID-19 cognitive deficits is crucial for developing targeted interventions and informing healthcare policies.
Objectives:
This study aims to systematically review and synthesize current evidence regarding post-COVID-19 cognitive impairments, focusing on their prevalence, affected cognitive domains, persistence over time and potential neuropathological mechanisms.
