ABSTRACT
Emerging evidence has suggested a close correlation between COVID-19 and neurodegenerative disorders. However, whether there exists a causal association and the effect direction remains unknown. To examine the causative role of COVID-19 in the risk of neurodegenerative disorders, we estimated their genetic correlation, and then conducted a two-sample Mendelian randomization analysis using summary statistics from genome-wide association studies of susceptibility, hospitalization, and severity of COVID-19, as well as six major neurodegenerative disorders including Alzheimer's disease (AD), amyotrophic lateral sclerosis, frontotemporal dementia, Lewy body dementia, multiple sclerosis, and Parkinson's disease. We identified a significant and positive genetic correlation between hospitalization of COVID-19 and AD (genetic correlation 0.23, P = 8.36E-07). Meanwhile, hospitalization of COVID-19 was significantly associated with a higher risk of AD (OR 1.02, 95% CI 1.01-1.03, P 1.19E-03). Consistently, susceptibility (OR 1.05, 95% CI 1.01-1.09, P 9.30E-03) and severity (OR 1.01, 95% CI 1.00-1.02, P 0.012) of COVID-19 were nominally associated with higher risk of AD. The results were robust under all sensitivity analyses. These results demonstrated that COVID-19 could increase the risk of AD. Future development of preventive or therapeutic interventions could attach importance to this to alleviate the complications of COVID-19.
