In my sheltered experience, I’ve never heard of this ailment outside of the entertainment industry. I have always assumed that it was code for “substance abuse recovery time.”
But I may just be ignorant. So what’s the straight dope?
A coworker was able to take a 3 month sabbatical due to exhaustion…
I have no idea what caused it… it wasn’t just the job since I got stuck with her duties for that time period…(I still do about half of what she did.)
My ICD-9 manual lists a number of things under the general heading of Exhaustion, including:
battle (reaction, stress, acute) 308.9
cardiac (see heart failure) 428.9
due to cold 991.8
heat 992.5
heat, due to salt depletion 992.4
heat, due to water depletion 992.3
mental (also psychogenic) 300.5
old age 797
Like KarlGauss said, it’s not really a diagnosis in and of itself, but a handy symptom. The actual diagnoses, you can infer from the dissimilar numbers, are pretty well all over the board.
Sometimes on the reports I get, patients are admitted with clinical data that reads “fatigue,” but that’s just what the patient complained of when they came in.
