I have no idea what PDSI is, i can only assume is some sort of ASI...like you said, it take a lot of time and training to learn the entire system, so it should have an ASI. I worked with the system for a year on a daily basis since i was 92A working in the SSA, and i don't think i learn not even a quarter of the system.
The term anorexia nervosa was established in 1873 by Queen Victoria âs personal physician, Sir William Gull. The term anorexia is of Greek origin: an - (á¼Î½-, prefix denoting negation) and orexis (á½ÏÎµÎ¾Î¹Ï, appetite), thus translating to nervous absence of appetite.he history of anorexia nervosa begins with descriptions of religious fasting dating from the Hellenistic era and continuing into the medieval period.
This notion is supported by the etymology (the Latin anorexia derives from the Greek privative prefix an and oregein, to reach after, desire), as well as by the clinical history: one of the first formal applications of the term in a clinical context invoked absence of appetite as anorexia's defining feature, stating that [t]he want of appetite is, I believe, due to a morbid mental state (Gull 25).
