Objective – Many different factors, both related to the individual and illness (“intrinsic” factors) and to the environment (“extrinsic” factors), contribute in different ways to the development of disability. Basing on data of literature, this review focuses the main “intrinsic” factors predicting disability in schizophrenia. Method – A systematic search on Mediline of all papers published during the period 1965-2001 was performed, using “schizophrenia”, “outcome”, “psychosocial outcome”, “social disability” and “social adjustment” as key words. Only papers reporting specifically data about predictive factors and psychosocial outcome variables were considered; prospective follow-up studies were considered, but retrospective and cross-sectional studies were also taken into account when data deriving from prospective studies were inconsistent. Results – Male sex predicts a higher disability among demographic factors; lower social and occupational adjustment are premorbid personality factors associated with higher disability; among factors related to illness, younger age at onset of illess, “nuclear”, “non paranoid” and in particular “deficit” forms of schizophrenia seem to predict more disability. The latter seems to be predicted also by higher levels of negative symptoms and neuropsychological deficits ; the role of depressive symptoms seems to be less supported by follow-up data; a continuous course of the illness predicts more disability, although some evidences show a progressive reduction of disability, at least in the long term. Conclusions – Disability shows a largely autonomous course respect to symptoms and has to be considered an independent parameter of outcome. Few intrinsic factors show a predictive role also in the long term.

Objectives - To present a comprehensive review of the studies assessing the frequency of PTSD in the general population, in clinical populations and among subjects at risk. Design - An extensive search was made using the Excerpta Medica Psychiatry CD-ROM 1980-1993 (October). Using post-traumatic stress disorder as a key word, a total of 1,057 papers published in this timespan were retrieved. A further search was made using the same key word with MEDLINE CD-ROM 1988-1993. A manual search was also performed for all issues of the Journal of Traumatic Stress. Results - A total of 135 studies meeting inclusion criteria were selected for this review. Almost two thirds (n = 86, 64%) of these studies were carried out in the United States; only 8 (6%) studies have been carried out in developed countries. The sample size ranges from a low of 11 subjects up to a high of 22,463 subjects. The mean sample size is 500 and the median is 108. In terms of assessment methods, in one third (n = 45, 33%) of the studies the investigators used a PTSD symptom checklist (either self- administered or administered by a clinician), based on DSM criteria, to generate a PTSD diagnosis. In more than in one third of the studies (n = 44, 33%) of the studies, a structured interview was administered (e.g., the DIS, the SCID, the SADS), while in the remaining surveys the diagnostic evaluation was based either on an un- structured clinical assessment or on the administration of other specific assessment instruments (e.g., M-PTSD, IES, SCL-90-R or others). In 77 studies (57%) the investigators based their assessment on DSM-III diagnostic criteria for PTSD, whereas in 55 studies (41 %) DSM-III-R criteria were employed. Prevalence rates are discussed separately for the different population groups. Conclusions - There has been a remarkable increase in the number and quality of epidemiological studies on PTSD over the past decade. A substantial amount of information is now available about the frequency of PTSD among different population groups and among at risk subjects, and about risk factors, common symptom patterns, and natural history of this disorder. However, a number of important limitations of these studies are to be noted and should be addressed by future research efforts.

Objective – Analysis of figures and characteristics of suicide behaviour in the area of Varese and the neighbouring northern towns (Valceresio, the valleys around Luino and northern Verbano), with the purpose of finding out preventing measures. Design – Epidemiological-descriptive survey. The 1995-1997 ISTAT death cards, included in the death files of the former USSL of Varese have been taken into consideration. Only those people who were resident at the suicide moment have been included in the survey. Afterwards the psychiatric service archives were consulted, to find any possible contact between the subjects in the ISTAT files and the psychiatric services themselves. With regard to these patients, some information such as suicide attempts, psychiatric pathology and first contact with the psychiatric services have been pointed out. Setting – Arcisate, Cittiglio, Luino and Varese districts, where the Community Mental Health Services 1 and 2 of “Azienda Ospedaliera Universitaria Macchi” of Varese operate. Main outcome measures – The suicide rates in the studied area have been reckoned and, through direct standardization, the rates of the single districts have been compared. Results – There were 78 suicides ( 24 females and 54 males): rate of 8.2 per 100.000. In accordance with the national trend, there is evidence of a general reduction of the suicide phenomenon, except among the youngest. Districts of Luino and Arcisate are geographic areas to examine in the time, because a wider sample could reveal a higher risk. Young and elderly people are the most affected among the males and, 55/64- year-old people, both males and females, are at higher risk. Suicide methods vary with the age. A high percentage of subjects are not married and with low education. Less than one third of the subjects had come into contact with the psychiatric service. Conclusions – These data allow a comparison with the national survey and an analysis of the suicide features in the study area. The purpose is to elaborate preventing strategies with multi- dimensional approach whose efficacy may be proved in the future by setting up a provincial observatory.

Scope – This overview analyses findings coming from researches that considered the interaction between depression and Alzheimer's disease (AD). Method – Information was collected from the Medline database and from a reasoned manual analysis of the published studies. Results – The prevalence of depressive symptoms in patients with AD is elevated (40-50%). The role of depression in the pathogenesis of AD (independent, prodromal symptom, factor of risk) still must be defined. Data on family history of depression suggest that AD could act as stimulus triggering depression from a basis of a genetic vulnerability. From a biological point of view the onset of depression could derive from an unbalance between cholinergic and noradrenergic systems. Psychological understanding sees depression as a reaction of mourning for the cognitive deficit. Current diagnostic instruments validated on patients with AD constitute a good aid for the clinician and the researcher. The identification of depression coexisting with AD is difficult, in absence of clear affective symptoms, since the cognitive, psychomotor and vegetative symptoms belong both to depression and to AD. The affective disorders most frequently reported are major depression and dysthymia. The use of antidepressant drugs with the lowest anticholinergic profile is strongly recommended. Good results have been obtained also using various psychoterapeutic interventions adapted for dementia sufferers. Conclusions – The current scientific debate is based on information still limited and sparse. Future analyses should consider a better definition of the hypotheses related to psychopathology in AD, a standardised definition of cases and selection procedures and a prospective longitudinal design.
