2、 1961).oKraepelin(1913)and other authors also reported a distinct psychotic syndrome associated with alcoholism that differed from delirium tremens(alcohol withdrawal with delirium),Wernickes encephalopathy,Korsakoffs psychosis and alcohol-induced dementia(Glass 1989a).oPsychotic manifestations may

3、also occur in other general medical or neurological disorders associated with alcohol dependence(Greenberg and Lee 2001).oEarly descriptions of a distinct psychotic syndrome associated with excessive alcohol use were based on case-studies and clinical observation.oBleuler(1916)termed the condition a

4、lcoholic hallucinosis.oFollow-up studies on patient groupsappeared from around the 1950s and described the features of what is currently known as:oAlcohol-induced Psychotic Disorder(AIPD)(APA,DSM-IV-TR 2000;DSM-5,2013),oor Psychotic Disorder due to the use of Alcohol(WHO ICD-10 1993).oEssentially th

5、e DSM criteria require:o(A)the presence of prominent hallucinations or delusions,o(B)evidence from the history,physical examination or laboratory findings that the symptoms developed within or during a month of alcohol intoxication or withdrawal.oThe symptoms are(C)not better accounted foroby a psyc

6、hotic disorder that is not substance-induced(e.g.symptoms precede substance use)and(D)do not exclusively occur during the course of a delirium.oDSM 5 stipulates thatothe period of onset should be“during or soon”after intoxicationoor withdrawal of alcohol and that the disturbance shouldocause clinica

7、l significant distress or impairment.oInitial studies on groups of patients did not compare patients with other diagnostic groups(Benedetti 1952;Burton-oBradley 1958;Victor and Hope 1958).oConclusions were based on clinical observations and follow-up studies overovariable periods of time.oFrom the 1

8、960s studies adopted a more systematic research approach(Glass 1989a).EpidemiologyoWhereas the lifetime risk for alcohol dependence is 1015%o(males)and 35%(females)(Schuckit 2005),only 23%ofosuch patients had psychotic symptoms(Victor and Adamso1953).oHowever,these figures did not exclude patientsoe

9、xperiencing psychotic symptoms associated with alcoholwithdrawalodelirium.It is estimated that AIPD patients representoa minority(33.1%)of the group of patients experiencingopsychotic symptoms associated with alcohol dependence(theorest being mostly associated with alcohol withdrawal delirium)o(Soyk

10、a et al.1988).oThe prevalence of AIPD in alcoholodependent patients varied between 0.4%and 0.7%(inpatients,oGermany)(Soyka 2008a),4%(inpatients,lifetime,oFinland)(Perl et al.2010)and 12.36%(Nepal)(Sedaino2013).A lifetime prevalence of 0.41%was reported in theogeneral population(Perl et al.2010).oThe

11、 German studyoexcluded patients with other substance abuse,whilst theoFinnish study included comorbid lifetime substance useo(20%)and other psychiatric disorders(76%).oAlcohol-withdrawal delirium was included in the alcohol-inducedopsychotic syndrome(AIPS)group and 13%of AIPD patientsodeveloped a pr

12、imary psychosis.oOverestimation of AIPDoprevalence may therefore be possible in the Finnish study,asothese comorbid disorders may also be associated with psychoticofeatures.oUnderreporting of AIPD is however alsoopossible because some patients may receive other diagnosesoeg.“dual diagnosis”,alcohol-

13、withdrawal delirium etc.or mayonot seek treatment because of favourable outcome(Soykao2008a;Perl et al.2010;Kumar and Bankole 2010).oAIPS was associated with a high mortality rate(37%over 8 years)o(Perl et al.2010),and“AIPD”(including patients with delirium tremens)was also identified as a risk fact

14、or for premature death(Mattisson et al.2011).oNo significant demographic differences(age,education,omarital status and employment)were found between maleoalcoholic patients with and without a history of psychosiso(Tsuang et al.1994).oThe age of onset of alcoholism reportedoin AIPD varied between 21.

15、4(Jordaan et al.2009),ando29.1 years(Tsuang et al.1994)with the latter study showingoa significantly younger age of onset of alcoholism for AIPDopatients than their non-psychotic male counterparts.The meanoage of onset of psychosis was significantly later in AIPD(36.2oand 37.4 years)compared to schi

16、zophrenia(24.8 ando32.8 years)(Jordaan et al.2009 and Soyka 1990).oThe sexoratios in patients with AIPD and alcohol-withdrawal deliriumowere similar(male/female:3.643.68:1 respectively)(Soykaoet al.1988).oHistories of higher(Tsuang et al.1994)and lower(Jordaanoet al.2009)levels of alcohol consumptio

17、n in AIPD comparedoto uncomplicated alcohol dependent patients were reported inostudies with varying methodologies.Higher rates of otherodrug use in AIPD compared to uncomplicated alcohol dependenceowere also reported(Tsuang et al.1994).Clinical featuresoAIPD is characterized by acute onset of audit

18、ory hallucinationso(Benedetti 1952;Victor and Hope 1958;Johanssono1961)and often persecutory delusions,in clear consciousnesso(Seitz 1951:Victor and Hope 1958;Soyka et al.1988;Soykao1990)and the absence of thought process disorder(Burton-oBradley 1958;Scott et al.1969;Cutting 1978;Surawicz 1980;oGla

19、ss 1989a,b)in individuals with heavy alcohol consumptionoThe hallucinations are characteristically in the form of derogatory voices(Glass 1989a;Soyka 1990).oWhile 10%ofpatients have symptoms suggestive of delirium in the acute phase(Benedetti 1952),the diagnosis of AIPD can only be made if psychotic

20、 symptoms persist in a clear sensorium(Soyka et al.1988).oInsomnia,anxiety,and depression(including suicidality)are symptomatic of alcohol-use disorders(Schuckit 2009).oSimilar symptoms were documented in early descriptions of AIPD(Bleuler 1916;Glass 1989a).oCompared with alcohol dependence,more pat

21、ients with AIPD had histories of depression(Tsuang et al.1994),and anxiety symptoms may be a risk factor for suicidality in AIPD(Jordaan et al.2009).Controversial issues relating to the diagnosisoControversy regarding the nosological status of the disorder has characterized the literature for severa

22、l years(Glass 1989a).oAIPD needs to be distinguished from alcohol-withdrawal delirium(Soyka et al.1988;Gross et al.1968),schizophrenia(Glass 1989a;Soyka 1990)and psychoses associated with general medical conditions such as epilepsy(Slater et al.1963;Roberts et al.1990;Nicolson et al.2006)and head in

23、juries(David and Prince 2005).oOther earlier descriptions and explanations for AIPD suggested an association with bipolar disorder(Schneider 1928),depression with paranoid features(Suwaki and Ishino 1976)and an association with concurrent personality traits(May andEbaugh 1953).oMoreover others quest

24、ioned the association with alcohol suggesting that the disorder could occur in the absence of alcoholism(Henderson and Gillespie 1936).Association with alcohol withdrawal delirium“delirium tremens”oAlcohol withdrawal delirium(“delirium tremens”)may exhibitofeatures similar to AIPD,suggesting a close

25、 relationshipobetween the two disorders.oEarly reports noted that the courseoof delirium tremens was shorter(Kraepelin 1913;Bowmanoand Jellinek 1941)and the hallucinations more likely visualothan auditory compared to AIPD(Kraepelin 1913).oIt was alsooobserved that patients with alcohol hallucinosis

26、were usuallyocorrectly orientated with intact attention and free of psychomotoroagitation(Bowman and Jellinek 1941).oCompared withoAIPD,patients with delirium tremens were older,had longeroalcohol abuse histories,seemed better equipped socially andointellectually and had significantly fewer head inj

27、uries thanothe hallucinosis group(Johansson 1961).oAnother study reported no differences in the marital,occupationaloand social status amongst patients with alcoholicohallucinosis,chronic alcoholism without psychosis and deliriumotremens.oIt was also noted that some patients with alcoholohallucinosi
