Since at least the late 80's, overtraining syndrome has been extensively studied and discussed in the field of sport medicine. It is know considered as an established entity, yet its pathophysiology remains unclear according to many authors (see for example the following review).
Overtraining syndrome essentially consists in a decrease in mood and physical performance occurring when an athlete fails to cope with high training load, despite adequate rest. In this type of situations, athlete's performance may even decrease, compared with their pre-overtraining level. Decrease in the training load is central in the management of the syndrome.
What strikes me is how this description could also apply to the form of cognitive exhaustion that many students experience during their curriculum. Anyone who has engaged in demanding studies has already felt exhausted, cognitively impaired and depressed during the most difficult times of the year, despite taking enough rest. This could suggest that there exists a form of "cognitive overtraining syndrome", but I cannot find any material dealing with the subject.
Has "cognitive overtraining syndrome" ever been identified as such? If so, how extensively has it been studied ?
Many thanks in advance.
