A Case Study of a White-Collar Employee Who Developed a Cerebral Hemorrhage with a Focus on Week-to-Week Over-Fatigue Conditions

摘要

Conditions leading to week-to-week over-fatigue conditions of a while-collar employee during a period of reduced work hours were studied. The employee developed a cerebral hemorrhage and the complete data related to his work during the six-month period preceding the onset of the hemorrhage were available. The onset of the hemorrhage was found to involve three characteristic factors, i. e., multiple responsibilities, over-fatigue lasting for a period of three months preceding the onset and absence of opportunities for psychophysiological recuperation during holidays. During the period leading up to the onset, we noted worsening of e-mail-related parameters, increasing actual work hours and reduction in sleeping hours in the subsequent order. Particularly on holidays, mood swings during waking hours and disturbed sleep caused by intense apprehension were also noted. In this case, the workload of the employee immediately preceding the onset of the cerebral hemorrhage was not unusually high. Therefore, it may be more useful to identify the week-to-week progression of over-fatigue during the workdays and holidays than to identify workload intensity immediately before the onset.
