Sleep deprivation and altered circadian rhythm affects the cognitive performance of an individual. Quality sleep is compromised in those who are frequently involved extended working hours shift work which found to be more common among nurses. Cognitive impairment leads fatigability, decline attention efficiency their workplace puts health patients' at risk.To find out prevalence its impact on cognition nurses.Sleep 97 female three male healthy nurses age 20-50 years was assessed by Epworth sleepiness scale (ESS). Cognition Montreal Assessment (MoCA) questionnaire. Mobile applications were used test vigilance, reaction time, photographic memory numerical cognition. The above said parameters during end day 3-4 days after start night shift.Poor quality observed 69% according ESS scores. analysed using Wilcoxon signed rank test. MoCA score lesser 66% (25.72) than (26.81). During night, 32% made mathematical errors. It also that, 71%, 83% 68% scored Stroop's colour test, vigilance tests respectively. Thus, statistically significant (p<0.001) nurses.Cognitive impaired nurses, due poor decreased alertness wake state. poses risks
