Relationship between fatigue and photosensitivity.

摘要

It is considered that photosensitivity is one of the most important factors to cause video-game epilepsy. Since photosensitivity is thought to cause various signs of hypersensitivity in the central nervous system and hypersensitivity is believed to be related to fatigue, whether fatigue is associated with photosensitivity was determined. The study group consisted of 68 healthy medical students attending Osaka City University Graduate School of Medicine. They completed questionnaires dealing with fatigue (Chalder Fatigue Scale) and photosensitivity. On simple regression analyses, fatigue score was positively associated with photosensitivity score. Similarly, on multiple regression analyses adjusted for age, gender, and sleeping hours, fatigue score was positively associated with photosensitivity score. Fatigue is associated with photosensitivity. Our findings provide new perspectives on fatigue.
