Investigation of cognitive decline in patients with COVID-19 syndrome within 12 weeks after infection

Aims: This study aims to investigate the effect of cognition in patients with COVID-19 within 12 weeks after infection. Methods: A prospective study included 30 patients with COVID-19 within three months after COVID-19 and 30 healthy controls.The age, gender and educational status of the participants were recorded.These patients underwent montreal cognitive assessment (MOCA) test. Statistical comparisons were performed using Mann witney U test and Pearson Chi-Square test. Results: There was a statistically significant difference in age between the patients with Covid-19 and the control group (p=0.02). No statistically significant difference was found between the two groups in terms of gender (p=0,06). The total MOCA test score of the COVID-19 patient group was found to be statistically significantly lower than the control group (p=0,00). The education level of the patients with COVID-19 was found to be statistically significantly lower than the control group (p=0.05) Conclusion: The results suggest that cognitive decline is a prolonged effect within 12 weeks after COVID-19.
