It is estimated that AIPD patients represent,a minority (33.1 %) of the group of patients experiencing,psychotic symptoms associated with alcohol dependence (the,rest being mostly associated with alcohol withdrawal delirium),(Soyka et al. 1988).,The prevalence of AIPD in alcohol,dependent patients varied between 0.4 % and 0.7 % (inpatients,Germany) (Soyka 2008a), 4 % (inpatients, lifetime,Finland) (Perl et al. 2010) and 12.36 % (Nepal) (Sedain,2013). A lifetime prevalence of 0.41 % was reported in the,general population (Perl et al. 2010).,The German study,excluded patients with other substance abuse, whilst the,Finnish study included comorbid lifetime substance use,(20 %) and other psychiatric disorders (76 %).,Alcohol-withdrawal delirium was included in the alcohol-induced,psychotic syndrome (AIPS) group and 13 % of AIPD patients,developed a primary psychosis.,Overestimation of AIPD,prevalence may therefore be possible in the Finnish study, as,these comorbid disorders may also be associated with psychotic,features.,Underreporting of AIPD is however also,possible because some patients may receive other diagnoses,eg. “dual diagnosis”, alcohol-withdrawal delirium etc. or may,not seek treatment because of favourable outcome (Soyka,2008a; Perl et al. 2010; Kumar and Bankole 2010).,AIPS was associated with a high mortality rate (37 % over 8 years),(Perl et al. 2010), and “AIPD” (including patients with delirium tremens) was also identified as a risk factor for premature death (Mattisson et al. 2011).,No significant demographic differences (age, education,marital status and employment) were found between male,alcoholic patients with and without a history of psychosis,(Tsuang et al. 1994).,The age of onset of alcoholism reported,in AIPD varied between 21.4 (Jordaan et al. 2009), and,29.1 years (Tsuang et al. 1994) with the latter study showing,a significantly younger age of onset of alcoholism for AIPD,patients than their non-psychotic male counterparts. The mean,age of onset of psychosis was significantly later in AIPD (36.2,and 37.4 years) compared to schizophrenia (24.8 and,32.8 years) (Jordaan et al. 2009 and Soyka 1990).,The sex,ratios in patients with AIPD and alcohol-withdrawal delirium,were similar (male/female: 3.643.68:1 respectively) (Soyka,et al. 1988).,Histories of higher (Tsuang et al. 1994) and lower (Jordaan,et al. 2009) levels of alcohol consumption in AIPD compared,to uncomplicated alcohol dependent patients were reported in,studies with varying methodologies. Higher rates of other,drug use in AIPD compared to uncomplicated alcohol dependence,were also reported (Tsuang et al. 1994).,Clinical features,AIPD is characterized by acute onset of auditory hallucinations,(Benedetti 1952; Victor and Hope 1958; Johansson,1961) and often persecutory delusions, in clear consciousness,(Seitz 1951: Victor and Hope 1958; Soyka et al. 1988; Soyka,1990) and the absence of thought process disorder (Burton-,Bradley 1958; Scott et al. 1969; Cutting 1978; Surawicz 1980;,Glass 1989a, b) in individuals with heavy alcohol consumption,The hallucinations are characteristically in the form of derogatory voices (Glass 1989a; Soyka 1990).,While 10 % ofpatients have symptoms suggestive of delirium in the acute phase (Benedetti 1952), the diagnosis of AIPD can only be made if psychotic symptoms persist in a clear sensorium(Soyka et al. 1988).,Insomnia, anxiety, and depression (including suicidality) are symptomatic of alcohol-use disorders (Schuckit 2009).,Similar symptoms were documented in early descriptions of AIPD (Bleuler 1916; Glass 1989a).,Compared with alcohol dependence, more patients 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 diagnosis,Controversy regarding the nosological status of the disorder has characterized the literature for several years (Glass 1989a).,AIPD 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 injuries (David and Prince 2005).,Other 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).,Moreover others questioned 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”,Alcohol withdrawal delirium (“delirium tremens”) may exhibit,features similar to AIPD, suggesting a close relationship,between the two disorders.,Early reports noted that the course,of delirium tremens was shorter (Kraepelin 1913; Bowman,and Jellinek 1941) and the hallucinations more likely visual,than auditory compared to AIPD (Kraepelin 1913).,It was also,observed that patients with alcohol hallucinosis were usually,correctly orientated with intact attention and free of psychomotor,agitation (Bowman and Jellinek 1941).,Compared with,AIPD, patients with delirium tremens were older, had longer,alcohol abuse histories, seemed better equipped socially and,intellectually and had significantly fewer head injuries than,the hallucinosis group (Johansson 1961).,Another study reported no differences in the marital, occupational,and social status amongst patients with alcoholic,hallucinosis, chronic alcoholism without psychosis and delirium,tremens.,It was also noted that some patients with alcohol,hallucinosis presented with delirious features (Scott 1967). In,a series of publications Gross et al. (1968, 1970, 1972a, b),challenged the importance of a clear sensorium and proposed,a spectrum of hallucinatory states which allowed for mild,clouding of consciousness in alcoholic hallucinosis.,These,studies compared the onset, clinical presentation, neuroimaging,findings, treatment response and clinical course in,patients with AIPD with that of other diagnostic categories,including alcohol-withdrawal delirium (delirium tremens),schizophrenia, alcohol dependence and healthy volunteers,(Johansson 1961; Scott 1967; Scott et al. 1969; Cutting,1978; Soyka et al. 1988, 2012; Soyka 1990; Tsuang et al.,1994; Aliyev and Aliyev 2005, 2008; Jordaan et al. 2009,2010, 2012; and Perl et al. 2010.,Epidemiology,
