By means of a clinical and follow-up method the author studied 74 patients with adolescent slowly progressive psychopath-like schizophrenia and prevalence of alcohol abuse in the clinical picture. It was established that in the period of the active development of the process in the framework of a protracted schizophrenic attack there are no signs of chronic alcoholism. Massive alcohol abuse is a symptom of the main psychopath-like state limited in time by the period of an attack and disappears with the outcome of the attack. In a relatively sluggish development of schizophrenia it would be justified to speak of co-existence of 2 diseases where schizophrenia is the main and it sharply modifies the picture of chronic alcoholism. These patients demonstrate a shorter period in the formation of chronic alcoholism and a distinct prevalence of its somatic signs over the mental.

The group of subjects consisted of 44 patients (attempters) who were admitted to hospital for treatment because of attempted suicide during a 3-month period in Norther Savo (in Eastern Finland), another 44 patients (non-attempters) admitted to hospital in the same period for other reasons serving as controls. The number of women was the same in both groups, and so was, in consequence, the number of men. The study compared the attempters with the non-attempters and, in addition, the patients coming from urban areas with those coming from rural areas, the ratio of the urban to the rural patients being the same in both groups. The study was based on personal psychiatric interviews with the patients, which took place in each case both immediately following the patient's admission and precisely 3 months afterwards. The results showed that schizophrenia was significantly more frequent in the rural than in the urban attempter group. By contrast, alcoholism and alcohol abuse were more frequent in the urban than in the rural attempter group. Compared with the urban patients, the rural patients tended to be physically more seriously desordered. Poisoning by drugs was a significantly more frequent means of attempted suicide in the urban than in th rural group. The patients in the latter group, again, had resorted oftener to the so-called "active" methods of attempted suicide. Of the attempters, 25% attempted suicide anew during the 3-month follow-up period, the corresponding figure for the non-attempter group being only 6%. During the follow-up period, a greater number of suicidal attempts was made by the patients in the rural group than by those in the urban group, and, as regards the intent to succeed, the attempts of the former were more serious than those of the latter. The so-called "active" methods were used more often by rural than by urban patients also during the follow-up period. All in all, the self-destructive behaviour exhibited during the follow-up period was graver in the rural than in the urban group.

In Dutch samples of treated heroin addicts, high prevalences of a heterogeneous psychiatric co-morbidity can be found with regard to Diagnostic and Statistical Manual (third edition) (DSM-III) classifications, Zung Depression Inventory, and sum scores of a 90-item Symptom Checklist (SCL-90). A high-threshold (N = 87) and a low-threshold (N = 116) program are compared with regard to psychopathology and severity of psychopathology. A consecutive admissions design was used. More than 50% of the respondents suffered from a lifetime DSM-III Axis I disorder (70% with antisocial personality disorder included), and 40% were still suffering from one of the disorders in the year preceding the interview. Schizophrenia was diagnosed five times as much as in normal population samples (5%). The most frequently diagnosed disorders were recurrent major depression, phobic disorders, alcohol abuse and dependence, dysthymic disorder, and antisocial personality disorder. The prevalences of DSM-III disorders, the total number of symptoms, and the score on the Zung Depression Inventory and 90-item Symptom Checklist were all significantly higher in treatment-seeking drug addicts entering the high-threshold program. Within each program, three clinically meaningful subgroups can be distinguished: one group with DSM-III Axis I lifetime or current psychopathology and/or antisocial personality disorder, one with antisocial personality disorder only, and one with neither DSM-III psychopathology nor antisocial personality disorder. Possibly, self-selection results in patients with more serious conditions entering more treatment-oriented facilities. Odds ratios show that schizophrenia and mood disorders and especially associated on a lifetime and current basis.

Many schizophrenics have a diagnosis of substance abuse or dependence. We evaluated whether drug or alcohol abuse is an independent risk factor for tardive dyskinesia (TD) in schizophrenia. In a consecutive admission, clinical study of 75 hospitalized schizophrenics, drug or alcohol abusers had significantly higher TD scores than nonabusers. The association of alcohol abuse or dependence with TD seemed independent from other risk factors for TD.

It is currently thought that genetic predisposition to imbalances in dopaminergic transmission may underlie several neurological disorders, including schizophrenia, manic depression, Tourette syndrome, Parkinson disease, Huntington disease, and alcohol abuse. Originally two receptors, D1 and D2, were thought to account for all of the pharmacological actions of dopamine. However, through homology screening three additional genes, D3, D4, and D5, and two pseudogenes closely related to D5 have been characterized. To begin our genomic and evolutionary analyses of the human D5 dopamine receptor gene and its two pseudogenes, we have mapped each of them to their respective chromosomes. By combining in situ hybridization results with sequence analysis of PCR products from microdissected chromosomes, somatic cell hybrids, and radiation hybrids, we have assigned DRD5 (the locus containing the functional human D5 receptor gene) to chromosome 4p16.1, DRD5P1 (the locus containing D5 pseudogene 1) to chromosome 2p11.1-p11.2, and DRD5P2 (the locus of D5 pseudogene 2) to chromosome 1q21.1.

Published estimates of the prevalence of substance abuse in schizophrenia were correlated with several aspects of the studies in which they were obtained. Higher estimates of alcohol and stimulant abuse were found in studies published more recently. Rates of alcohol abuse were particularly high in one rural investigation. Rates of stimulant abuse were highest when patients were asked directly about use of stimulants. Increased prevalence estimates in more recent years could not be attributed to method of assessing substance abuse, method of defining substance abuse, or characteristics of the study sample.

Abuse of alcohol and other drugs by mental patients has been reported extensively in the past decade, especially in the USA. It has seemed to us that drug abuse has become more common among mental patients treated at this psychiatric hospital and at outpatient clinics in Jerusalem in recent years. Therefore, 100 patients admitted consecutively were questioned with regard to alcohol and drug abuse. A quarter of the male patients were diagnosed as having both a psychiatric disorder and drug abuse. Drug abuse was even more common among male schizophrenics aged 26 to 35, but only 2 reported alcohol abuse. Drugs used were mainly opiates (heroin and methadone) and hashish, and in most cases both. The results indicate that mental patients, especially young men with schizophrenia, may be another risk group for drug abuse in Israel.

As part of a systematic research project on the influence of gender factors on age at onset, symptomatology, and course of schizophrenia, data on gender differences in age at onset and symptomatology of schizophrenia from the WHO Collaborative Study "On Assessment and Reduction of Psychiatric Disability" were compared between seven research centres of three different cultural regions. Results on age at onset of five European centres confirmed the well known fact of an earlier onset in men. The earlier onset in women seen in Khartoum and Ankara could be attributed to patient selection because male/female differences in age at onset and male/female ratios in the various samples covary. In the Islamic centres no relevant gender differences in real age at onset and in symptomatology could be detected as probable causes of earlier hospitalisation of women. Major gender differences in symptomatology were found in the Balkan centres of Sofia and Zagreb with a high prevalence of delusional symptoms in women and depression in men. In Western Europe centres, nuclear schizophrenic symptoms were equally prevalent in either sex, while nonspecific symptoms like irritability and tiredness (more frequent in women) and maladaptive illness behaviours like alcohol abuse and social withdrawal (more frequent in men) differed between the sexes. Explanatory hypotheses and the implications of these results are discussed.

Relationships between alcoholism and anxiety disorder are well known by clinicians. Studies have recently shown that the prevalence of alcohol abuse or dependence is very high in patients with panic disorder with or without agoraphobia (Thyer et al., 1986; Bibb and Chambless, 1986). The aims of this study were to determine the prevalence and comorbidity of alcohol abuse and dependence in a population of panic outpatients who were consecutive referrals for treatment of panic disorder (PD) in an anxiety clinic. Patients were interviewed with the Schedule for Affective Disorders and Schizophrenia-Lifetime Version Modified for the study of anxiety disorders (SADS-LA) which is a standardized and semi-structured interview allowing to make diagnoses according to RDC, DSM III and DSM III-R criteria. One hundred and three panic patients (39 males and 64 females) were included in the study. Their mean age was 38.5 years (SD: 11.6). In this sample, 24.3% met the DSM III-R criteria for alcohol abuse and 8.7% those for alcohol dependence. Among these patients, 26.2%, abused of benzodiazepines and 16.5% of them of other substances. We found a high comorbidity rate. In fact, 6.8% of the patients met diagnostic criteria for PD alone, 31.0% for one more diagnosis, 29.1% for two more and 33.0% for three or more besides PD. In this study, we found an association between alcohol abuse and the presence of a lifetime diagnosis of major depressive episode and/or other addictive behaviors. Otherwise, alcohol abuse did not occur more often in patients suffering from panic disorder associated with agoraphobia and/or social phobia.

Gender differences in the specificity of drug versus alcohol transmission were examined among 201 opioid addicts and their 877 first-degree relatives using direct interviews and a structured family history method based on the Schedule for Affective Disorders and Schizophrenia Research Diagnostic Criteria. A strong association of parental alcoholism with alcoholism among the proband addicts was found, suggesting some specificity for drug versus alcohol abuse. We also found that among the 477 siblings, those with alcoholism alone did not have parents with drug abuse and those parents with drug abuse did not have children with alcoholism alone. Rates of parental alcoholism were higher in alcoholic female than in alcoholic male probands, suggesting greater female "loading" was needed in order to become alcoholic. This increased loading in women was also found among the siblings, but alcoholic parents appeared to transmit a nonspecific tendency for either drug or alcohol abuse to their female children. Thus, it may take a greater "dose" of parental transmission for a woman to become a substance abuser, and transmission of alcoholism may be specific in men, but not in women.
