Objective – Even in countries whose mental health services are comparatively well resourced, the care offered to those in the early stages of psychotic illnesses is not what it could be. Patients often have to progress to chronicity before receiving adequate interventions, by which stage there has been great potential for harm, not only through the psychosis, but also to the quality of life of the individual who has often missed or not completed adequately, several important developmental tasks. Further, evidence indicates that delay in treatment is positively associated with poorer outcome. This paper puts the case for early intervention in psychosis. Method – Based on the experience of the Early Psychosis Prevention and Intervention Centre in Melbourne, the paper reviews the evidence for and the criticisms of, early intervention. Using the concept of indicated prevention, it suggests ways in which clinicians can improve the interventions available to those experiencing the onset of psychosis and suggests that prepsychotic intervention may be possible. Results – Evidence discussed in this paper indicates that the development of mental illness is a major health issue in young people; that there is a positive correlation between duration of untreated psychosis and outcome; that it is possible to identify a proportion of those at high risk of developing mental illness; that through intervention it may be possible to reduce the transition rate to illness. Conclusion – Primary prevention is beyond the capacity of our present knowledge. Indicated prevention in the form of early intervention and optimal, sustained treatment is a paradigm for which there is increasing supportive evidence. It is a paradigm which is appealing to clinicians, patients, families and which has the potential to reduce the secondary impact of serious mental illness such as suicide, stigma, isolation and reduction in social status.

Objective – Two forms of early intervention in psychosis are currently being proposed — intervention before the onset of illness with at-risk individuals and intervention after the onset of psychosis. Method – The risks and potential benefits associated with these two approaches were examined using published data and Bayes probability theorem. Results -Claims for benefits from early intervention in established psychosis go back more than two hundred years to the nineteenth-century advocates for asylum construction. Theoretical support for early intervention in psychosis rests on data suggesting that a longer duration of untreated psychosis (DUP) is associated with poor outcome. The association of DUP with outcome, however, appears to be inseparable from the confounding influence of the good outcome expected in recent-onset psychosis. Although some researchers advocate treating people with premorbid features of psychosis or other high-risk indicators, adequate screening measures and effective interventions are not yet available. The most promising current screening measure, if applied to the general population, would be accurate only two percent of the time. The accuracy of these measures can be improved by screening only those patients who are referred to a clinic, but this strategy will result in many cases in the population-at-large being overlooked. Discussion – The risks and potential benefits associated with the two early intervention approaches are very different. The provision of optimal treatment early in psychosis could produce benefits, but people with brief, good-prognosis psychotic episodes are likely to receive unnecessary treatment. Screening the general population or patients referred to a clinic will have little public health impact on the incidence of schizophrenia. There is likely to be considerable negative impact on those who are inaccurately labeled as being at imminent risk of psychosis and are treated accordingly.

Objective – To evaluate the prevalence of dementia among persons born in the year 1930 or before, who were living in Granarolo, Ravenna province, on December 31, 1991. Design – Population study, carried out in two phases: in the first was phase all persons were administered two screening tests for dementia. In the second phase, persons who screened positive underwent detailed clinical and cognitive assessments. Main outcome measures – The Mini Mental State Examination (MMSE) and the Global Deterioration Scale (GDS) were administered as screening tests. In the second phase the screened-positive subjects underwent a general and neurological examination, and a detailed neuropsychological assessment. Results – Of the 557 participants, 56 were clinically diagnosed as demented. Twenty-nine persons were diagnosed as affected by Alzheimer's disease (AD) and 14 patients by vascular dementia (VaD). The crude prevalence ratios for dementia were 9.1% (95% C.I.= 5.29−12.89) for men and 12.7 % (95% C.I.= 8.84−16.6) for women. The prevalence of all dementias, as well as AD, increased steeply every five years of age for both men and women up to 90 years of age. Women had higher prevalence of all dementias and AD than men, more evident in the advanced ages. Conclusions – Our findings are in agreement with similar studies carried out in European populations, showing that prevalence of dementia increases with increasing age. If we consider that in Italy the oldest (those 80 years and older) are the fastest growing part of the elderly population, we can expect that dementia will be a major emerging public health problem, as it is one of the most common diseases in the very elderly and a major cause of disability and mortality.

Objective – The study aims to identify the predicting factors of hospitalization in patients who come in Emergency Room with psychiatric symptoms. Method – Cross-sectional study using data collected by E.R. of S.Gerardo Hospital in Monza from 1st of June 1995 to 31 May 1997. Inclusion criteria were age older than 18 and the need for psychiatric evaluation. The influence on disposition decision of demographic, clinical and service variables were assessed. Main outcome measures – Data were collected by a questionnaire designed for the study and administered by a trained psychiatrist. Statistical analysis was performed by univariate analysis and logistic regression. Results – 2076 cases were evaluated. Univariate analysis yielded higher odds of hospitalization for patients between 39 and 48 years of age, unmarried, unemployed, affected by schizophrenia, mood disorders or personality disorders. A linear trend was reported between hospitalization and severity of illness, siucide risk and aggressivness. While anxiety proved to be a protective factor, hallucination, delusion, lack of insight, psychomotor inhibition, agitation, confusion, destructive behaviour, odd behaviour, abnormal consciousness and previous hospitalization increase inpatient disposition. On Monday and Friday higher frequency of hospitalization was observed. Logistic regression confirm the role of age, symptoms, aggressive behaviour, severity of illness, suicide risk, and, among services variables, days of the week. Conclusion – Clinical variables proved to be the main predictors of hospitalization, and an important role is played by the availability of outpatients services: hospitalization was more frequent in the days closer the week-end, when the outpatient services are closed.

Objective – The aim of the present study is to provide an epidemiological study about suicide in Verbano-CusioOssola province, between January 1990 and December 2000. Design – The present study is based on the acquisition of data through the examination of model 45, that registers all the cases of violent death and suicide, filed in Verbania Republic Procuration. Setting – The Verbano-Cusio-Ossola province extends 2,255 Km2 and counts 161,248 inhabitants. The Procuration in Verbania has territorial jurisdiction on the whole province of our study. Main outcome measures – The data obtained were presented in terms of descriptive analysis, evaluation of standardised rates of the province of Verbano-Cusio-Ossola. In order to appreciate the differences in comparison with the mean rates of northern Italy, Standardised Mortality Rates (SMRs) with the confidential intervals (IC 95%) have been used. Results – In the eleven years period considered, 297 cases of suicide were notified at the Court with a rate of 16.74 per 100,000 inhabitants. The trend of suicide in the period examined is heterogeneous with significant differences between males and females. The analysis of SMRs points out that the incidence of suicide is higher in the province of VCO than in Italy in the same decade and that this difference is mostly due to an higher rate of suicide among women. The analysis of social-demographic parameters of the examined population confirms the data from international literature: suicide is more present in elderly, in widowers and in the retired. Conclusions – The present study means to provide a description of the suicide phenomenon, in a specific geographical and cultural context, in order to point out the problematic sides in a diagnostic-clinical point of view that may be an incentive to a larger preventive care.
