The DSM-5 is the text psychiatry professionals use to assess and diagnose mental illness. It codifies what IS an illness, a neurosis, or a tic. There has been much controversy in recent years with regard to what is considered a mental aberration, and what is not.
Homosexuality used to be in the text, and was voted out by their governing board in the early 70s.
‘Jumping the Shark’ refers to when something goes beyond the pale. It refers to the downturn and eventual demise of the popular 70s TV series Happy Days, wherein Fonzie, the show’s ‘cool guy’, picked up a dare to perform a water ski jump over a shark (while wearing his trademarked leather jacket, of course!) A long distance from the James Dean / Marlon Brando – modelled character he originally copied. From Rebel Without A Cause to Rebel Without A Clue.
The DSM-5 recently added caffeine withdrawal as an actual mental disorder.
Now, I’ve experienced caffeine withdrawal (as well as over-use) many times. I am addicted to caffeine, currently in the form of Coke Zero, and it’s more-caffeinated cousin, Diet Coke. I like coffee, but in central Arizona, when the temps top 100, I prefer a colder beverage.
I may one day again choose to deprive myself of caffeine. And, I expect to experience at least some of the possible side effects in so doing: restlessness, nervousness, excitement, insomnia, flushed face, diuresis (having to pee a lot), gastrointestinal disturbance, muscle twitching, rambling flow of thought and speech, tachycardia or cardiac arrhythmia, periods of inexhaustibility or psychomotor agitation (unintentional motion, say, rapidly bouncing one leg) – (Philly.com)
While there may be some psychological and physiological side-effects from withdrawing from caffeine, personally, I hardly think it needs to be listed in the DSM-5.
I don’t know if the elements of the Twinkie Defense are in there, already. I’m afraid to look.
