Research Abstract

We aimed to examine the validity of the concept of presenteeism in university students by neuroimaging using near-infrared spectroscopy. Subjects were 22 university students. Although we observed a statistically significant increase in the oxygenated hemoglobin concentration during the word fluency test in the healthy student group, no significant change was found in cerebral hemodynamics in the presenteeism group. We suggest that a functional decline in the prefrontal cortex may be observed in students with presenteeism.
