This article reports the initial results of a prospective study on the prevalence of psychiatric disorders in the Dutch population aged 18-64. The objectives and the design of the study are described elsewhere in this issue. A total of 7076 people were interviewed in person in 1996. The presence of the following disorders was determined by means of the CIDI: mood disorders, anxiety disorders, eating disorders, schizophrenia and other non-affective psychoses, and substance use disorders. Psychiatric disorders were found to be quite common. Some 41.2% of the adult population under 65 had experienced at least one DSM-III-R disorder in their lifetime, among them 23.3% within the preceding year. No gender differences were found in overall morbidity. Depression, anxiety, and alcohol abuse and dependence were most prevalent, and there was a high degree of comorbidity between them. The prevalence rate encountered for schizophrenia was lower (0.4% lifetime) than generally presumed. A comparison with findings from other countries is made. Relevant determinants of psychiatric morbidity were analysed.

The literature suggests that substance abuse treatment for schizophrenia patients should consider both the patients' readiness for active treatment and matching phases of intervention with phases of the patient's acceptance of his or her dual problems. This study assessed the suitability of existing measures of "readiness to change" for use with individuals with schizophrenia. Outpatients (n = 39) with a diagnosis of schizophrenia and alcohol and/or drug dependency or abuse were given three measures to assess the stage of readiness to change. Results suggested that there was no agreement between stages defined by the interviewer and stages defined by self-report. This has implications for assessing readiness to change in terms of substance use in a population with schizophrenia.

Although older adults typically underutilize mental health services, problems associated with dementing illnesses, chronic medical illnesses, affective disorders, social isolation, and multiple medication use, among other phenomena, have increased referrals of the elderly to psychiatric emergency services. The present study reviewed characteristics of elderly adults referred to a psychiatric emergency outreach/screening service. Of all individuals for whom a referral was made, 24% were aged 60 or older. Among those older adults referred, 63% were seen by screening service personnel; 37% did not meet screening criteria or voluntarily sought mental health services. Diagnoses of individuals evaluated included dementia (27%), affective disorders (27%), schizophrenia (16%), psychosis (12%), alcohol abuse (7), and diagnosis deferred (11%). Findings highlight the limited options available for mental health care of the aged.

For the early and correct diagnosis of the comorbidity of schizophrenia and alcoholism, a valid laboratory marker would be most helpful in clinical practice. Seventy schizophrenics admitted to a general psychiatric unit of an urban hospital located in a large industrial area in Germany prospectively underwent a detailed addiction history, the Munich Alcoholism Test (MALT) and determinations of serum gamma-glutamyltransferase (gammaGT) and carbohydrate-deficient transferrin (CDT). Cutoff levels for laboratory tests represented the 95th percentile of data obtained from 100 matched healthy controls. Using the MALT, we found evidence of concomitant alcohol consumption in 42.8% of the study patients. The sensitivities of gammaGT and CDT for detecting alcohol abuse (confirmed using DSM III-R criteria) were 70.6 and 58.8%, respectively. Our data suggest that the MALT can be used as a reliable screening test for alcohol use in schizophrenia. In neuroleptic-treated schizophrenics with pathological gammaGT, but low MALT scores, the corresponding CDT may serve as a highly specific marker to verify a concomitant alcohol abuse.

Individuals with a severe mental illness and substance use disorder tend to have medical and social problems and to make slower progress in treatment than those who have either disorder alone. Nevertheless, little attention has been paid to the discovery of effective methods of modifying substance use in the severely mentally ill (SMI). The purpose of this study was to collect qualitative data as a way to help identify techniques that might help to change patterns of substance use in the SMI. The participants were 21 men and women who were psychiatric clinic outpatients and who had a current schizophrenia spectrum diagnosis. A total of 18 participants had a lifetime diagnosis of alcohol abuse or dependence, and 21 lifetime other drug diagnoses were recorded for the sample. These individuals participated in focus group discussions about topics related to substance use and people's experiences with trying to quit. The results showed that participants identified several therapeutic and extratherapeutic factors that helped them to initiate and maintain changes in their substance use, as well as factors that hindered change. The findings are related to knowledge about the effectiveness of substance use disorder treatment techniques in general, and implications of the data are discussed for the conduct of integrated treatment of individuals with severe mental illness and a substance use disorder.

Twin research in medicine and psychology has blossomed during the last decades. A brief presentation of twin research methods is given, followed by a review of psychiatric studies, particularly Norwegian ones. The Nordic investigations are of great importance because many of these studies have been able to avoid shortcomings in sampling by linking national twin registers to disease registers. This procedure is of consequence for the estimation of heritability. Twin research shows that the genetic contribution to Alzheimer's disease, manic-depressive (bipolar) disorder, schizophrenia and childhood autism is relatively strong, whereas genetic factors play a minor role in common depressions, anxiety and somatoform disorders, and alcohol abuse. Since the concordance rates are far from 100 percent in most of these illnesses, environmental factors must also be important.

In recent years, magnetic resonance imaging (MRI) of the hippocampus has been extensively studied on neurological and psychiatric disorders. Particularly in studies on schizophrenia and mood disorders, findings regarding the hippocampal involvement have been most controversial. Previously, minor volume loss of the hippocampus in alcoholism, a major comorbidity alongside psychiatric disorders, has been reported but no data exist on the hippocampal volumes in subtypes of alcoholism. In this study, MRI was used to measure volumes of the hippocampus in late-onset type 1 alcoholics and early-onset type 2 alcoholics. The type 2 alcoholic subjects were also violent offenders with antisocial personality disorder, derived from a forensic psychiatric sample. All were non-psychotic and legally competent. Normal volunteers, representing a wide age range, served as a controls group. Compared to the controls, the right, but not left, hippocampi were significantly smaller in both alcoholic groups. While there was no correlation between the hippocampal volumes with age in the control subjects, there was tendency towards decreased volumes with aging and also with the duration of alcoholism in the type 1 alcoholic subjects. Surprisingly, there was a significant positive correlation between the right hippocampal volume and age in the type 2 alcoholics. This study provides further in vivo evidence that type 1 alcoholism, in general, is associated with a minor loss in hippocampal volume. It is suggested that type 2 alcoholism, in general, similarly displays a minor decrease in hippocampal volume, but this decrease is unevenly distributed within the type 2 category, being weighted towards the younger subjects. These effects suggest differences between the two alcoholic groups, and raise the possibility that the observed effects within the type 2 category are due to other factors than the cumulative acquired effects related to alcohol abuse, such as primary personality psychopathology.

Several case studies indicate that clozapine use is associated with reductions in the use of nicotine, alcohol, or illicit drugs. Although not designed to assess clozapine, this study explored a posteriori the effects of clozapine on alcohol and drug use disorders among schizophrenia patients. Among 151 patients with schizophrenia or schizoaffective disorder and co-occurring substance use disorder who were studied in a dual-disorder treatment program, 36 received clozapine during the study for standard clinical indications. All participants were assessed prospectively at baseline and every 6 months over 3 years for psychiatric symptoms and substance use. Alcohol-abusing patients taking clozapine experienced significant reductions in severity of alcohol abuse and days of alcohol use while on clozapine. For example, they averaged 54.1 drinking days during 6-month intervals while off clozapine and 12.5 drinking days while on clozapine. They also improved more than patients who did not receive clozapine. At the end of the study, 79.0 percent of the patients on clozapine were in remission from alcohol use disorder for 6 months or longer, while only 33.7 percent of those not taking clozapine were remitted. Findings related to other drugs in relation to clozapine were also positive but less clear because of the small number of patients with drug use disorders. This study was limited by the naturalistic design and the lack of prospective, standardized measures of clozapine use. The use of clozapine by patients with co-occurring substance disorders deserves further study in randomized clinical trials.

Admission to secure hospital facilities is a rare outcome for people with intellectual disability with or without concomitant psychosis. The present study compares people with mild intellectual disability with and without schizophrenia resident in the Scottish and Northern Irish State Hospital, Carstairs, to matched mild intellectual disability controls, also with and without schizophrenia, in the community. It is hoped that this study may identify socio-demographic, clinical or historical predictors which may lead to admission to secure hospital facilities for people with mild intellectual disability. One hundred and eight subjects were identified from two previous studies which concerned State Hospital patients and patients with intellectual disability with and without schizophrenia. Four experimental groups were derived: (1) 14 individuals with comorbid intellectual disability and schizophrenia who had been resident in the State Hospital; (2) 34 comorbid community control subjects; (3) 33 individuals with intellectual disability and no psychosis who had been resident in the State Hospital; and (4) 27 community control subjects with mild intellectual disability. The four groups were compared on a range of socio-demographic, historical and clinical variables obtained from case records and subject interviews. Relative to community controls, people with intellectual disability and no psychosis in the State Hospital are likely to be single, to have a later age of first psychiatric hospital admission, and to have a history of previous suicide attempts, alcohol abuse or drug misuse. Subjects with comorbid intellectual disability and schizophrenia in the State Hospital are more likely to be male, to have an early age of first psychiatric admission, and to have no family history of either schizophrenia or intellectual disability. Strategies aimed at addressing suicidal behaviour, alcohol and drug misuse amongst people with intellectual disability may facilitate a reduction in the number of admissions to high-security hospitals in the UK. In people with comorbid intellectual disability and schizophrenia, males with an early age of onset and no known family history are more likely to require care and treatment in a secure psychiatric setting. Such comorbid subjects may be suffering from a particular malignant form of schizophrenia, manifesting in childhood as cognitive impairment prior to the early onset of psychosis in teenage years.

The appearance of cavum septi pellucidi (CSP) has been already connected with developmental disorders or with serious psychiatric diseases (schizophrenia, maniac-depressive disorder, aggressiveness or similar). During our investigation of CSP, group of alcoholics seemed to be interesting for investigation and comparison with the groups of schizophrenics and people with violent behavior. We obtained CSP in 205 out of 670 fixed brains (429 male and 241 female) of persons aged from 14 to 89 (mean +/- SD: 53.28 +/- 16.57), 85 cava belonged to our group of interest. Prevalence of CSP in aforementioned groups was significantly higher than in the rest of examined population. Only in the group of 20 to 39 years of age all kinds of obtained pathologies were present. Alcoholics with CSP suffered from cardiovascular diseases and died accidentally and aggressive persons were the only drug addicts in our examined group and they had the shortest life span. 34 out of 41 schizophrenics had no data about prior diseases and disorders and they were the ones who committed suicide frequently. Intensive demyelinization of corpus callosum and transformation of potential space between laminae of septum pellucidum to the actual one could explain the CSP appearance among alcoholics. To our opinion, cavum septi pellucidi might be used as an additional marker of organic brain changes in long term alcohol abuse, as a consequence of demyelinization due to lipolytic effect of ethanol, and lower cerebral blood flow.
