Risk of cognitive decline and dementia in older adults with Covid-19: review
A systematic review found that 65% of older COVID-19 patients experienced new cognitive impairment, with a mean MoCA score of 23.34, highlighting the need for further research and management protocols.

A systematic review and meta-analysis investigated the risk of cognitive decline and dementia in older adults diagnosed with COVID-19. The study included 18 studies with a total of 412,957 COVID-19 patients aged 65 and older. The findings revealed that 65% of these patients experienced new-onset cognitive impairment, as indicated by a mean Montreal Cognitive Assessment (MoCA) score of 23.34 out of 30. The analysis suggested that the time since infection positively correlated with cognitive outcomes, indicating potential recovery over time. The review highlighted the need for further research to understand the long-term cognitive effects of COVID-19, particularly regarding new-onset dementia and the impact of repeated infections. The authors emphasized the importance of developing diagnostic and management protocols for COVID-19 patients experiencing cognitive impairment, given the significant implications for health and social well-being in the aging population.
- 65% of older adults with COVID-19 showed new-onset cognitive impairment.
- The mean MoCA score for COVID-19 patients was 23.34, indicating cognitive issues.
- Time since infection may improve cognitive outcomes.
- Further research is needed to explore the link between COVID-19 and dementia.
- Development of management protocols for cognitive impairment in COVID-19 patients is essential.

Study: Covid-19 reinfections likely have similar severity to original infection
A NIH-funded study on COVID-19 reinfections in 213,000 Americans found severe initial infections correlated with similar reinfection severity. Long COVID was more common after first infections. Lower albumin levels may indicate reinfection risk.
Covid-19 Infections and Cognitive Function
A study by Bas Weerman et al. explored COVID-19 infections' link to cognitive function using UAS data. Pre-pandemic cognitive tests predicted infection status, but subjective cognition did not. No negative association found post-baseline cognition, hinting at reverse causation influence.
Risk of long Covid declined over course of pandemic
The risk of long COVID has decreased due to vaccination and virus changes. Vaccination accounts for 70% of risk reduction. Long COVID affects 10% post-COVID individuals. Dr. Ziyad Al-Aly's study stresses vaccination's role.
Covid has long-term detrimental effects on vascular function in college students
A study on 37 college students recovering from COVID-19 revealed significant impairments in endothelial function and increased blood pressure, indicating lasting cardiovascular effects and the need for ongoing health monitoring.
