Objectives: The SARSCOV-2 is known to cause Microvascular and Macrovascular thrombotic phenomena in the vascular system, which has been found to increase the chances of blood clotting in the brain. Microvascular subclinical thrombotic phenomena that lead to impairment in cognitive functions have not been studied much in this pandemic. The study aims to determine whether this SARS CoV-2 produces cognitive impairment in the person who has suffered from COVID-19. If it produces cognitive impairment, then whether it persists even after one month or not or whether it resolves. Materials and Methods: This longitudinal prospective study was carried out after taking institutional Ethical committee clearance. People in the age group of 18 to 60 years who were diagnosed as COVID-19 Positive, and got recovered and discharged, were assessed at the time of discharge, after one month and after three months using cognitive assessment battery (PGI MEMORY SCALE, DSST, TMT, ADULT PROTEUS and MMSE). Results: A total of 205 subjects were included in the study.71% are males, and 28.3% are females. The majority that is 36% of the study population, is between 40-49 years. Parameters like TMT and PGI MEMORY have been statistically significant between discharge day, after one month, and three months follow-up. The age group of 40 to 48 years was most affected, with a frequency of 75%. Conclusions: The study has shown that cognitive impairment can happen after COVID 19 disease.
