Initially this term was used to describe mental exhaustion among those immersed in intense cognitive pursuits, the term evolved over time, eventually finding a place in the DSM-4 (Diagnostic and Statistical Manual of Mental Disorders) in 1960, associating it with the rigors of excessive academic demands.
