Neurological features of COVID-19 have been reported in addition to the respiratory manifestations, but cognitive dysfunction has been scarcely described. And cognitive assessment has not been studied in asymptomatic subjects. We compared the cognitive assessment scores between asymptomatic SARS-CoV-2 infected subjects with that of controls to detect mild cognitive impairment by the Montreal Cognitive Assessment test. Asymptomatic COVID-19 subjects secured lower scores in certain domains of the MoCA in comparison with the controls. The domains were visuoperception (2.4 ± 0.7 vs2.8 ± 0.7, p = 0.032), naming (3.6 ± 0.5 vs3.9 ± 0.2, p = 0.016) and fluency (0.9 ± 0.6 vs1.6 ± 0.7, p =  < 0.001). Also, older aged COVID-19 positive subjects scored lower in the MoCA when compared to the younger people. Our study shows that even otherwise asymptomatic COVID-19 subjects have cognitive deficits in certain subdomains and suggests the need for a detailed psychometric assessment especially in the elderly population.

Context: Coronavirus disease 2019 (CoViD 19) pandemic has induced the government to initiate strict control measures. Improvements to these measures and shortcomings could be gleaned with the understanding of the knowledge, attitude and practices (KAP) of the public. Aims: The aim of this study the CoViD 19 KAP of a south Indian state population. Settings and Design: This was a Cross-sectional observational study. Subjects and Methods: We conducted an online survey to elicit this information. Statistical Analysis Used: Mean, Standard deviation, Binomial and Multinomial logistic regression. Results: Of the 1837 subjects who answered the survey, 70% were youth (16–29 years), 54% were postgraduates and 47.8% were desk jobholders. The mean knowledge score was 9.92 ± 2.37/14 and 94.44% secured at least above-average score. The subjects had a positive (70%) attitude towards the CoViD 19 situation and 77% of subjects followed good preventive practices. However, we found that women, people with low education and nonmedical background were associated with poor knowledge and practices. The attitude was poor in subjects occupant in physical works. Conclusions: The health policy would better serve the purpose of the groups with poor scores are targeted.
