Cognitive decline and dementia in older adults diagnosed with Covid-19
A systematic review found a 65% incidence of new cognitive impairment in older adults with COVID-19. Time since infection may improve outcomes, highlighting the need for further research and diagnostic protocols.

A systematic review and meta-analysis have revealed a significant association between COVID-19 and cognitive decline in older adults. The study analyzed 18 studies involving over 800,000 participants, finding that 65% of older adults diagnosed with COVID-19 experienced new-onset cognitive impairment. The average Montreal Cognitive Assessment (MoCA) score for these patients was 23.34, indicating cognitive issues. The research suggests that the time elapsed since infection may improve cognitive outcomes, as cognitive impairment appears to decrease over time. The findings underscore the need for further investigation into the long-term cognitive effects of COVID-19, particularly regarding its potential to exacerbate dementia or lead to new cases. The study emphasizes the importance of developing diagnostic and management protocols for older COVID-19 patients experiencing cognitive decline, as this could significantly impact their quality of life and healthcare strategies. The authors call for more extensive research to understand the mechanisms behind COVID-19-related cognitive impairment and the role of vaccinations in mitigating these effects.
- COVID-19 is linked to a 65% incidence of new-onset cognitive impairment in older adults.
- The average MoCA score for COVID-19 patients indicates cognitive impairment.
- Time since infection may positively influence cognitive outcomes.
- Further research is needed to explore the relationship between COVID-19 and dementia.
- Development of diagnostic protocols for cognitive impairment in COVID-19 patients is essential.
