30、ir underlyingmechanismsisneeded for research to moveforward.Inhis Aphorisms,Hippocrates definedmelancholia(忧郁症)，an early understandingof depression,as a stateof“fears andlosingcourage,if they last a longtime.”It was caused,he believed,byan excessof bile(胆汁)in the body(theword“melancholia”is ancientG

31、reek for“blackbile”).BEversince then,doctorshave struggledto createa morepreciseandaccurate definitionof theillnessthatstillisnt wellunderstood.In the 1920s,the German psychiatristKurt Schneiderarguedthatdepressioncouldbedivided into two separateconditions,each requiringa differentformof treatment:d

32、epressionthatresultedfromchanges in mood,whichhe called“inner depression”,anddepressionresultingfromreactionsto outside events,or“reactivedepression”.Histheorywas challengedin 1926,whentheBritishpsychologistEdward Mapotherarguedin theBritishMedical Journalthattherewas no evidence fortwo distincttype

33、sof depression,andthattheapparentdifferencesbetween depressionpatientswerejustdifferencesin theseverity of thecondition.CToday,Schneiders subtypes have largely fallen out of favor,but over the years,many more definitionswere offered in their place.In 1969,the American psychologist Rollo May wrote in

34、 his book Love and Will that“depression is the inability to construct a future,”while the cognitive psychologist Albert Ellis argued in 1987 thatdepression,unlike“appropriate sadness”,stemmed from“irrational beliefs”that left sufferers ill-equipped to dealwith even mild setbacks.DIn 1952,the America

35、n Psychiatric Association tried 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 Diagnosticand Statistical Manual,depression was listed under the broad category of“disorders without clearly definedphysi

36、cal cause”.The DSM-III,published in 1980,was the APAs first attempt to clarify the definitions of specificdisorders by listing their symptoms;the new edition included guidelines for differentiating depression from otherdisorders,and outlined eight symptoms of depression,included“poor appetite or sig

37、nificant weight 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 ow

38、n chapter.The diagnostic criteria were mostly unchanged,withthe exception of one additional symptom:“Depressed mood most of the day,nearly every day,as indicated byeither subjective report(e.g.,feels sad or empty)or observation made by others(e.g.,appears tearful).”E Some scientists believe that the

39、 DSM-V definition is still too vague.As the psychiatrist Daniel Goldbergnoted in the journal World Psychiatry in 2011,many of the DSM symptoms are opposites,which can make itdifficult for researchers working to develop a more precise understanding of the condition.“A patient who haspsychomotor retar

40、dation(精神运动性阻滞)，hypersomnia(嗜睡)，and gaining weight is scored as having identicalsymptoms 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 atJohns Hopkins University attempted

41、 to identify subtypes of depression by studying the symptoms ofnearly2,000patients.However,the researchers were unable to find much of a pattern connecting gender,familyhistory,symptoms,and the degree of the condition(mild to severe).“Depression is of different kind,”theyconcluded,adding that“the se

42、verity 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 captureda huge population of patients with“widely varying associations with the pattern of co-morbidity(共 病)，pers

43、onality 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 of psychology at the University of Notre Dame,is thatin medi

44、cal term,depression is considered a syndrome rather than a disease.While a disease is a specific conditioncharacterized by a common underlying cause and consistent physical traits,a syndrome is a collection of signs andsymptoms known to frequently appear together,but without a single known cause.In

45、a paper published in June inthe journal Current Directions in Psychological Science,Monroe called for scientists to begin defining depressionwith more precision.“It is in this vague and imprecise realm that problems can arise,”he wrote,“and vagueinsights based on imperfect similarities and differenc

46、es 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,isbecause they still dont have a clear answer for what causes depression.In the 1960s,the dominant hypothesis wasthat it stemmed from a chemical im

47、balance in the brain,specifically from lower levels of the neurotransmitterserotonin(血清素).As a result,drug companies poured resources into developing“selective serotonin reuptakeinhibitors”(SSRIs),drugs that increased type of antidepressantdespite the fact that research has shown that lowerof seroto

48、nin do not necessarily cause depression for all individuals.And in 2010,a review of three decades worthof studies on antidepressants found that while SSRIs can be helpful for severely depressed people,theireffectiveness“may be minimal or nonexistent”in those with mild or moderate depression.IBruce C

49、uthbert,the director of adult translational(平 动)research and treatment development at theNational Institute of Mental Health(NIMH),thinks that part of the problem is that researchers have largely focusedtheir attention on finding a one-size-fits-all treatment that doesnt exist.“When you do a clinica

50、l trial,youregetting a bunch of people who are depressed,but theyre actually very different,”he said.“Its like comparingapples,pears,and oranges.Youre not going to see a significant effect.Youre not going to be able to say,Thistreatment works for fruits.”Trying to create a singular treatment for dep
