Hoping for increased efficiency, decisiveness and creativity in the months ahead? There are titles for that, too. As we settle down to our New Years

18、【 C2】 _, well turn in droves to self-help books, hoping to find our own best selves in their pages. But a book neednt lecture to leave its imprint. The truth is that all good literature changes us, and a growing body of research suggests you might do better browsing through fiction for support in【 C

25、Needs a New Definition AMany psychiatrists believe that a new approach to diagnosing and treating depressionlinking individual symptoms to their underlying mechanismsis needed for research to move forward. In his Aphorisms, Hippocrates defined melancholia(忧郁症 ), an early understanding of depression,

26、 as a state of “fears and losing courage, if they last a long time. “ It was caused, he believed, by an excess of bile(胆汁 )in the body(the word “melancholia“ is ancient Greek for “black bile“). BEver since then, doctors have struggled to create a more precise and accurate definition of the illness t

27、hat still isnt well understood. In the 1920s, the German psychiatrist Kurt Schneider argued that depression could be divided into two separate conditions, each requiring a different form of treatment: depression that resulted from changes in mood, which he called “inner depression“ , and depression

28、resulting from reactions to outside events, or “reactive depression“. His theory was challenged in 1926, when the British psychologist Edward Mapother argued in the British Medical Journal that there was no evidence for two distinct types of depression, and that the apparent differences between depr

29、ession patients were just differences in the severity of the condition. CToday, Schneiders subtypes have largely fallen out of favor, but over the years, many more definitions were offered in their place. In 1969, the American psychologist Rollo May wrote in his book Love and Will that “depression i

30、s the inability to construct a future,“ while the cognitive psychologist Albert Ellis argued in 1987 that depression, unlike “appropriate sadness“ , stemmed from “irrational beliefs“ that left sufferers ill-equipped to deal with even mild setbacks. DIn 1952, the American Psychiatric Association trie

31、d to standardize the definitions of mental illnesses, including depression, by creating a taxonomy(分类法 )of mental illnesses. In the first edition of the Diagnostic and Statistical Manual, depression was listed under the broad category of “ disorders without clearly defined physical cause“. The DSM-I

32、II, published in 1980, was the APAs first attempt to clarify the definitions of specific disorders by listing their symptoms: the new edition included guidelines for differentiating depression from other disorders, and outlined eight symptoms of depression, included “poor appetite or significant wei

33、ght loss“ and “complaints or evidence of diminished ability to think or concentrate“. If an adult met four of the eight symptoms, the manual counseled, he or she would meet the criteria for clinical depression. In the DSM-V, published in 2013, depressive disorders were finally allocated their own ch

34、apter. The diagnostic criteria were mostly unchanged, with the exception of one additional symptom: “Depressed mood most of the day, nearly every day, as indicated by either subjective report(e. g. , feels sad or empty)or observation made by others(e. g. , appears tearful). “ ESome scientists believ

35、e that the DSM-V definition is still too vague. As the psychiatrist Daniel Goldberg noted in the journal World Psychiatry in 2011, many of the DSM symptoms are opposites, which can make it difficult for researchers working to develop a more precise understanding of the condition. “ A patient who has

36、 psychomotor retardation(精神运动性阻滞 ), hypersomnia(嗜睡 ), and gaining weight is scored as having identical symptoms as another who is agitated, sleeping badly, and has weight loss,“ Goldberg wrote. FMany recent studies have verified Goldbergs concerns. In 2000, for example, a group of researchers at Joh

37、ns Hopkins University attempted to identify subtypes of depression by studying the symptoms of nearly 2,000 patients. However, the researchers were unable to find much of a pattern connecting gender, family history, symptoms, and the degree of the condition(mild to severe). “Depression is of differe

38、nt kind,“ they concluded, adding that “the severity of an episode appears to be more informative than the pattern of symptoms. “ And in 2010, researchers in Germany testing the validity of the DSM-IV definition found that the criteria captured a huge population of patients with “ widely varying asso

39、ciations with the pattern of co-morbidity(共病 ), personality traits, features of the depressive episode and demographic characteristics. “ The results, they argued, “challenge our understanding of major depression as a similar categorical entity. “ GPart of the problem, said Scott Monroe, a professor

40、 of psychology at the University of Notre Dame, is that in medical term, depression is considered a syndrome rather than a disease. While a disease is a specific condition characterized by a common underlying cause and consistent physical traits, a syndrome is a collection of signs and symptoms know

41、n to frequently appear together, but without a single known cause. In a paper published in June in the journal Current Directions in Psychological Science, Monroe called for scientists to begin defining depression with more precision. “ It is in this vague and imprecise realm that problems can arise

42、,“ he wrote, “and vague insights based on imperfect similarities and differences eventually may prove to be clear oversights. “ HPart of the reason that scientists are still working in the “vague and imprecise realm“ , as Monroe put it, is because they still dont have a clear answer for what causes

43、depression. In the 1960s, the dominant hypothesis was that it stemmed from a chemical imbalance in the brain, specifically from lower levels of the neurotransmitter serotonin(血清素 ). As a result, drug companies poured resources into developing “selective serotonin reuptake inhibitors“(SSRIs), drugs t

44、hat increased the amount of serotonin in the brain. SSRIs are still the most commonly prescribed type of antidepressantdespite the fact that research has shown that lower levels of serotonin do not necessarily cause depression for all individuals. And in 2010, a review of three decades worth of stud

45、ies on antidepressants found that while SSRIs can be helpful for severely depressed people, their effectiveness “may be minimal or nonexistent“ in those with mild or moderate depression. IBruce Cuthbert, the director of adult translational(平动 )research and treatment development at the National Insti

46、tute of Mental Health(NIMH), thinks that part of the problem is that researchers have largely focused their attention on finding a one-size-fits-all treatment that doesnt exist. “ When you do a clinical trial, youre getting a bunch of people who are depressed , but theyre actually very different,“ h

47、e said. “ Its like comparing apples, pears, and oranges. Youre not going to see a significant effect. Youre not going to be able to say, This treatment works for fruits. “ Trying to create a singular treatment for depression, Cuthbert said, is like trying to create one for cancer: too unspecific to

48、actually be helpful. “Our current diagnostic system is ninning out of steam for research. “ “While DSM has been described as a Bible for the field, it is, at best, a dictionary, creating a set of labels and defining each,“ the NIMH director Tom Insel wrote in 2013. JIn 2010, Insel invited Cuthbert,

49、who was then working as a psychology professor at the University of Minnesota, to help the NIMH develop a new framework for defining mental illness. The result, unveiled in 2013, was the Research Domain Criteria(RDoC), a system created to flip the way researchers think about mental disorders. Unlike the DSM, RDoC isnt organized by disorder: instead, its organized around specific symptoms, like fear, anhedonia(the inability to feel pleasure), and willingness or unwilling
