Acute Alcoholic Hallucinosis: A Review.

Acute alcoholic hallucinosis is a psychotic disorder characterized by a predominance of auditory hallucinations with delusions and affective symptoms in the clinical picture. Classically, it develops as part of the alcohol withdrawal syndrome. The prevalence of acute alcoholic hallucinosis ranks second among alcohol-related psychoses after alcohol delirium. The study aimed to systematize the scientific data on the history of alcoholic hallucinosis, its pathogenesis, clinical presentation, and treatment approaches. A literature search was performed in PubMed, Scopus, Google Scholar, and eLibrary. The following words and combinations were used as search strings: (alcoholic hallucinosis OR alcoholic psychosis OR alcohol-related psychosis OR alcohol-induced psychosis OR alcohol-induced psychotic disorder OR complicated alcohol withdrawal syndrome) NOT (animal OR rat OR mouse). The relevant information concerning the history of acute alcoholic hallucinosis, its pathogenesis, clinical picture, and treatment approaches was systematized and summarized. This review presents relevant findings regarding acute alcoholic hallucinosis. Limitations of the review include the use of heterogeneous and mostly descriptive studies and studies on small cohorts of patients.

Healthcare Utilisation, Morbidities and Alcohol Use Monitoring Prior to Alcoholic Psychosis Diagnosis.

AIMS: The aim of this study was to describe healthcare utilisation, morbidities and monitoring of alcohol use in patients prior to a diagnosis of alcoholic psychosis in order to inform the early identification of patients at risk. METHODS: Using linked general practice and hospitalisation data in England (April 1997 to June 2014), we identified 1731 individuals (≥18 years) with a clinical recorded diagnosis of alcoholic psychosis and 17,310 matched controls without the disorder, we examined all prior general practitioner (family doctor) visits, hospitalisations, medically recorded morbidities and alcohol assessment/interventions records. Poisson regression models were used to compare rates of healthcare utilisation in people with alcoholic psychosis to those without. Logistic regression models were used to evaluate the association between alcoholic psychosis and prior morbidities. RESULTS: Patients with alcoholic psychosis showed increased levels of healthcare utilisation at least 5 years prior to their diagnosis. The most common reasons for prior healthcare visits were seizures and injuries and there was >4-fold higher rate of seizures, unintentional injuries and self-harm incidents among these patients up to 10 years prior to diagnosis, compared to the control population. A high proportion (78%) of patients had their alcohol consumption recorded, 50% had a record of heavy drinking but only one in five had any evidence of receiving an alcohol-related intervention. CONCLUSION: Patients present more often with seizures and injuries than the general population several years prior to a diagnosis of alcoholic psychosis. These visits represent opportunities for preventive action and imply that we may be missing opportunities to intervene.

Treatment of Alcohol-Induced Psychotic Disorder (Alcoholic Hallucinosis)-A Systematic Review.

AIMS: To evaluate the effectiveness of evidence based treatments for alcohol-induced psychotic disorder (AIPD) as described by ICD-10 and DSM-5, a condition that is distinct from schizophrenia and has a close relationship with alcohol withdrawal states. METHOD: Systematic review using PRISMA guidelines. RESULTS: Of 6205 abstracts found, fifteen studies and ten case reports met criteria and were examined. Larger studies examined the use of first-generation antipsychotic drugs, reporting full or partial remission in most patients. Newer case reports report similar results using second generation antipsychotic drugs. Novel treatments, such as those acting on GABA receptors reported low numbers of patients in remission. Some large studies report the successful use of standard alcohol withdrawal treatments. CONCLUSION: The findings of our systematic review are inconclusive. There was significant heterogeneity between and within studies. Significant publication bias is likely. Randomized control trials of more carefully delineated samples would produce evidence of greater clinical utility, for example, on differential effectiveness of antipsychotics and optimal length of standard alcohol withdrawal treatments. AIPD patients who show poor treatment responses should be studied in greater depth. SHORT SUMMARY: This systematic review of alcohol-induced psychotic disorder treatment found 15 studies and 10 case reports of relevance. Older studies of first-generation antipsychotics reported full or partial remission in most patients, as did newer studies with second-generation antipsychotics. Novel drugs reported low remission rates. Standard alcohol withdrawal treatments were successful.

[Alcohol-induced psychotic disorder: a systematic literature review]. / Psychotische stoornis door alcohol: een systematisch literatuuroverzicht.

BACKGROUND: From the second half of the 19th century eminent psychiatrists began referring to alcohol-induced psychotic disorder (AIPD) as a specific alcoholic psychosis. Over the last decades interest in AIPD seems to have declined: the last review dates form 1989. AIM: To review the recent literature on AIPD, revive interest in the disorder, evaluate the current scientific evidence and assess its clinical value. METHOD: We performed a Medline search based on the following terms: 'Psychoses, Alcoholic' [Mesh] OR 'alcohol induced psychotic disorder' OR 'alcoholic hallucinosis' OR 'alcohol hallucinosis'. Our search was restricted to articles written in English or Dutch and published between 1-1-1988 and 31-1-2013. RESULTS: We found 164 papers, from which we selected 21 for further discussion. The quality of the papers selected was variable, most of the papers being the result of clinical research. The most important findings referred to epidemiology: 0.4% lifetime prevalence in the general population, 4.0% in patients with alcohol dependence. We found only limited evidence of psychopathological differentiation between delirium and primary psychotic disorder. Correct diagnosis of AIPD is important because of the implications regarding the length and nature of the treatment: short or long course of antipsychotics, referral to a substance-abuse unit. CONCLUSION: AIPD has survived as a clinical entity. However, scientific evidence of this is limited. Further research is needed because it is vitally important that the patient receives the most appropriate treatment.

Alcohol-induced psychotic disorder: a review.

While alcohol-induced psychotic disorder (AIPD) is well recognised, relatively little is known about the condition. We undertook a review of the literature to identify studies on the epidemiology, clinical manifestations, underlying neurobiology and treatment of AIPD. Few prospective studies have been conducted on AIPD. Recent advances have focussed on epidemiological, phenomenological, neuro-imaging, treatment and outcome issues. Current evidence suggests AIPD can be clinically distinguished from alcohol-withdrawal delirium and schizophrenia. The disorder may be more common than previously recognised depending on the inclusion criteria applied. AIPD is associated with high co-morbidity with other psychiatric disorders, high re-hospitalization and mortality rates and suicidal behaviour. Concurrent dysregulation of several neurotransmitter systems may be involved in the pathogenesis of hallucinations in alcohol dependence, and neuro-imaging studies suggest perfusion abnormalities to various brain regions. Antipsychotic treatment remains the preferred treatment for AIPD. The prognosis appears less favourable than previously believed, yet usually good when abstinence can be maintained.

Effects of alcohol on the offender's sanity-Issues of criminal law and psychiatry in light of findings of research.

The present report is the result of research on the causes of insanity or issuing opinions about the causes of insanity or diminished sanity perpetrators in criminal proceedings conducted in Poland (CEE). Research has shown the impact that has, in fact, use or abuse of alcohol and other alcoholic diseases on the status of the accused in criminal proceedings. This publication presents not only the results but also the basic regulations - valid in Poland and in other European countries - with respect to the responsibility of the perpetrators insane, with diminished sanity and being in a state of inebriation at the time of committing a criminal act.

[Rethinking criminal responsibility: practical application of operational diagnosis and gnostic into expert testimony].

There had been argument concerning the difference between the agnostic approach and the gnostic approach to the psychiatric perspective of criminal responsibility until the landmark ruling by the 3rd court of the Japanese Supreme Court in 1984. The decision upheld the gnostic approach and affirmed that the defendant's criminal responsibility should be based on such factors as psychopathology, motive, modus operandi, situation surrounding the crime, and pre-morbid personality, as long as the offense was not directly motivated by the delusion or hallucination. The gnostic explanation includes so many various factors that the psychiatric testimony cannot easily be objective, while agnostic experts can find a conclusion about criminal responsibility only by psychiatric diagnosis. To establish a standard, the authors summarized the means of determination of criminal responsibility. The authors also discussed various topics related to criminal responsibility including Asperger's syndrome, illicit drug intoxication, and prescribed drug intoxication.

Emergency room medical clearance: an educational problem.

The term "medically clear" has a greater capacity to mislead than to inform correctly. The overuse of this term, especially in emergency room settings, may indicate difficulties in medical education and in the consultation/referral process between psychiatry and other specialties; further, it results in poor patient care. Nonpsychiatric physicians may prematurely refer patients as medically clear because of their unfamiliarity or discomfort with clinical psychiatry. Psychiatrists often ask for medical clearance of patients to hide their discomfort with or antipathy toward clinical medicine. The use of emergency room settings for interspecialty collaboration and training helps minimize the underlying difficulties that lead to the use of this term by fostering psychiatric skills in nonpsychiatrists and a sense of medical identity in psychiatrists.

"Organic brain syndromes": an empirical study and critical review.

The authors found that all but 3 of 80 randomly chosen patients in a Veterans Administration hospital who had been given a primary nonspecific neuropsychiatric diagnosis (organic brain syndrome, organic psychosis, chronic brain syndrome, etc.) could be assigned to specific diagnostic categories. Diagnosis was based on chart review and thorough neurological and clinical evaluation. Senile and alcoholic dementia and Korsakoff's syndrome were seen most often, and 15% of the patients were diagnosed as having functional disorders of the mental state. The authors review the organic brain syndrome diagnosis in light of this and other evidence. They believe that fractionation into more specific diagnoses is essential to further understanding of this group of diseases. Use of the general term can result in inappropriate or no treatment; further, it hampers essential psychological, pharmacological, and biomedical research on these disorders.

Specific major mental disorders and criminality: a 26-year prospective study of the 1966 northern Finland birth cohort.

OBJECTIVE: The purpose of the study was to examine the quantitative risk of criminal behavior associated with specific mental disorders. METHOD: An unselected 1966 birth cohort (N = 12,058) in Northern Finland was prospectively studied until the end of 1992. The investigation started during the mothers' pregnancy, and the data on the subjects' family characteristics, mental and physical development, living habits, psychiatric morbidity, and criminal records were gathered at various times. RESULTS: The prevalence of offenses was the highest among males with alcohol-induced psychoses and male schizophrenic subjects with coexisting alcohol abuse, and more than half of the schizophrenic offenders also had problems with alcohol. Eleven (7%) of the 165 subjects who committed violent crimes were diagnosed as psychotic. Male schizophrenic subjects had a moderately high risk for violent offenses, but the risk for other types of crimes was not elevated significantly. Odds ratios for criminal behavior were adjusted according to the socioeconomic status of the childhood family and were the same as or slightly lower than the crude odds ratios for all disorders except schizophrenia and mood disorders with psychotic features. CONCLUSIONS: The results indicate that the risk of criminal behavior was significantly higher among subjects with psychotic disorders, even though the socioeconomic status of the childhood family was controlled. The higher risk for violent behavior was associated especially with alcohol-induced psychoses and with schizophrenia with coexisting substances abuse. The results suggest that schizophrenia without substance abuse may also be associated with a higher risk of offenses, but this finding is tentative and requires further investigation.

Altered NMDA glutamate receptor antagonist response in individuals with a family vulnerability to alcoholism.

OBJECTIVE: A family history of alcoholism is a risk factor for the development of ethanol dependence. Ethanol is an antagonist of the N-methyl-d-aspartate (NMDA) glutamate receptor, and alterations in NMDA receptor function are thought to be involved in ethanol abuse and dependence. The purpose of this study was to determine in healthy individuals with no ethanol dependence whether response to the NMDA receptor antagonist ketamine would differentiate those with a family history of ethanol dependence from those without such a family history. METHOD: Healthy subjects between the ages of 21 and 30 received 40-minute intravenous infusions of saline, low-dose ketamine (0.1 mg/kg), and high-dose ketamine (0.5 mg/kg) on three separate test days in a randomized order under double-blind conditions. The healthy individuals with at least one first-degree relative and another first- or second-degree relative with ethanol dependence (N=16) were compared with those who had no family history of ethanol dependence in any first- or second-degree relative (N=29). Outcome measures included the Brief Psychiatric Rating Scale, Clinician-Administered Dissociative States Scale, verbal fluency, Hopkins Verbal Learning Test, a biphasic alcohol effects scale, visual analog scales of mood states, and ketamine levels. RESULTS: During ketamine infusion, individuals with a family history of ethanol dependence showed an attenuated response in terms of perceptual alterations and dysphoric mood relative to those without such a family history. CONCLUSIONS: These data suggest that alterations in NMDA receptor function may contribute to subjective response to ethanol and therefore also to the risk of developing alcoholism.

Pathological intoxication--is there such an entity?

Pathological intoxication appears as a diagnostic term in DSM-II and DSM-III, is defined in a psychiatric dictionary and is described in several textbooks. Still, is there really such an entity? Is the small amount of alcohol inbibed incidental rather than causal? It should be borne in mind that alcohol is the popular explain-all of our culture and as such is used as an excuse for everything from sexual indiscretions to well-planned "impulsive" acts. It is likely--and evidence is presented for this conclusion--that so-called cases of pathological intoxication are really dissociative reactions. The existence of pathological intoxication as an entity must remain in doubt unless the disorder can be reproduced under controlled conditions.

The alcohol provocation test.

An alcohol provocation test is described wherein a 20% solution of alcohol was injected intravenously in 57 subjects with three major goals: 1) To determine criminal culpability. 2) To determine alcohol activation of the electroencephalogram. 3) To aid in treatment of the chronic alcoholic through personal feedback. The test was found safe and reliable. Results are interpreted on the basis of behavioral observations and blood alcohol levels. Advantages of such a test are reviewed.

The effects of antecedent substance abuse on the development of first-episode psychotic mania.

We examined associations of antecedent drug and alcohol abuse with age of onset of bipolar disorder and the time to hospitalization in a sample of 59 patients presenting with their first episode of psychotic mania. Patients with first-episode manic or mixed bipolar disorder with psychotic features were recruited from consecutive hospitalizations and evaluated using structured diagnostic instruments. Antecedent alcohol abuse was present in 12 patients (20%), and antecedent drug abuse in 19 (32%). Antecedent alcohol abuse was associated with a later age of onset of the bipolar disorder, although antecedent drug abuse was not associated with age of onset. Patients with antecedent drug or alcohol abuse required hospitalization sooner than those without. These preliminary findings suggest that patients with bipolar disorder and antecedent alcohol abuse may have a later onset of their affective illness, perhaps representing a subgroup of patients in whom previous alcohol abuse is necessary to precipitate an affective episode. Regardless, the presence of antecedent substance abuse leads to more rapid hospitalization in these patients. Our results should be considered preliminary, given the small sample size and the post-hoc design of the study. Additional prospective studies of patients with new onset bipolar disorder and antecedent substance abuse syndromes are needed to further clarify the complex relationships between substance abuse and bipolar disorder.

Substance abuse and emergency psychiatry.

Given the high rates of comorbidity, patients commonly present with multiple diagnoses to PESs or crisis services. Clinicians must be well versed in the evaluation, differential diagnosis, and treatment of patients with substance-abuse disorders or other Axis I, II, or III conditions if they are to provide state-of-the-art treatment of patients in need of emergency care.

Alcohol withdrawal syndromes - prediction from detailed medical and drinking histories.

The predictability of the withdrawal syndrome on the basis of the drinking history immediately prior to detoxification was investigated in 43 patients admitted to an inpatient Alcoholism Service; a pilot study consisted of 17 patients and a subsequent definitive study of 26. After obtaining informed consent, blood alcohol concentrations were measured. Each subject was extensively interviewed to obtain a medical and dietary history and to determine alcohol and drug intake in the past week and months. The levels of intoxication and withdrawal signs/symptoms were assessed on admission and daily for at least 3 days. Urine and blood toxicology screens were also performed for 19 subjects. Contrary to widespread impressions, most of the patients were able to give a detailed account of their drinking and drinking-related behavior in the 3 days prior to admission and 73% could do this for the previous 7 days. Subjects were consistent in their reporting; 85% gave drinking histories consistent among interviews conducted independently by the medical, research and counseling staff. A significant correlation (r = 0.55; P less than 0.01) was found between the severity of withdrawal and the total alcohol intake in the days immediately prior to admission. No significant correlation was evident between withdrawal severity and the number of years of heavy drinking. Amounts of benzodiazepines (diazepam and flurazepam) administered by the medical staff during the first 3 days of withdrawal and for the total hospital stay were also found to be significantly correlated with withdrawal severity (r = 0.58; P less than 0.01 for both). Regression analyses of these data also confirmed the statistically significant relationships between alcohol intake and withdrawal severity and between withdrawal severity and amounts of benzodiazepines used for detoxication. Of special interest was the finding that 50% of the subjects reported no hangovers within he past year or more and 23% reported that they had never experienced a hangover, despite very heavy drinking. In addition, only 50% of the patients had regularly consumed coffee or any caffeine-containing substance; this low incidence of caffeine intake was statistically significantly less than that found in extensive surveys of the general population in which only 3-10% eschew caffeine-containing beverages. It is concluded that the severity of alcohol withdrawal can be related to a cluster of variables among which is recent alcohol intake. The present results are, at the same time, consistent with previous observations of the appreciable differences among individuals in the consequences of abrupt cessation of chronic alcohol consumption.

Decrease in alcohol tolerance: clinical significance in alcohol dependence.

In 237 male inpatients with alcohol dependence, clinical, demographic and biochemical data were analyzed in relation to alcohol tolerance. All subjects had a history of marked tolerance. At the time of assessment, 46% of subjects continued to meet the criteria for marked tolerance and 54% of the subjects reported a loss or decreased tolerance. Subjects with decreased tolerance were older than those with high tolerance and had a longer duration of illness. The age of onset was similar in both groups. Patients with decreased tolerance had more mental confusion and psychotic symptoms, and were less likely to be currently married.

Accuracy of hospital discharge data: five alcohol-related diseases.

Accuracy of hospital discharge register data was studied by comparing 954 randomly selected abstracts to the respective medical records. The average percentages of agreement were: date of birth 98, date of admission 96, date of discharge 94, area of residence 93, principal diagnosis 91, disposition on discharge 89, marital status 84, third diagnosis 83, second diagnosis 76, social group 74, occupation 60, and source of admission 49. Accuracy of items was not related to alcohol etiology. An analysis of variance indicated that the number of items in agreement varied by both diagnosis and type of hospital.

Increased sensitivity to picrotoxin as an index of physical dependence on alcohol in the mouse.

A relatively simple and rapid method has been developed to induce tolerance to and dependence on alcohol in mice. Alternating intraperitoneal injections of metabolically stable tert-butanol and ethanol for 4 consecutive days resulted in a physical dependence on alcohol, which was quantified by the latency and ED50 of picrotoxin-induced CNS hyperexcitability--myoclonic and tonic seizures and mortality--during the withdrawal period. The data indicate that alcohol-dependent animals in the withdrawal period are more susceptible than alcohol-naive controls to picrotoxin. Withdrawal hyperexcitability can be quantified by the ED50 of picrotoxin.
