To Study the Effect of Excessive Daytime Sleepiness on Critical Fusion Frequency in Medical Students
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 4
Abstract
Background: Sleep is a physiological process essential for life. Sleep loss leads excessive daytime sleepiness (EDS) which leads to many like complications like impaired memory and cognition, decreased work performance, increased chances of vehicular accidents etc .The Critical Flicker Fusion (CFF) test provides an index of central nervous system activity or cortical arousal which measures arousal and alertness. Thus, this study is carried out with aim of deciphering the effect of Excessive daytime sleepiness on Critical fusion frequency in medical students Objective: To compare ESS and CFF between normal and daytime sleepiness group and correlate EDS with CFF. Material and methods: This is a descriptive cross sectional study carried out in 124 undergraduate medical students in the age group of 18-25 yrs at Sri Devaraj Urs medical college ,Kolar. Institutional ethical clearance was obtained. Epworth Sleepiness Scale (ESS) questionnaire was administered to assess daytime sleepiness and CFF was measured using CFF M1 Model instrument and the frequency was measured from the recorded data using Sweepgen software. Results: Excessive daytime sleepiness is seen among 25% of the subjects. CFF was significantly (p=0.001) decreased in daytime sleepiness group compared to normal group. ESS shows weak negative correlation with CFF in daytime sleepiness group. Conclusion: CFF an index of cortical arousal and alertness decreased with excessive daytime sleepiness group compared to normal deciphering that sleepiness leads to decreased cortical arousal and alertness and increases mental fatigue.
