ABSTRACT Samenvatting In dit artikel wordt aan de hand van het voorbeeld psychose allereerst het concept staging uitgelegd.Vervolgens wordt in een casusbespreking een voorbeeld van behandeling van subklinische psychotische symptomen en gebleken risicosymptomen voor een eerste psychose, besproken. Behandeling met cognitieve gedragstherapie, zoals in deze casus wordt op dit moment onderzocht op de positieve effectiviteit ervan op het beloop van subklinische psychotische klachten. De groep patiënten met een verhoogd risico op een psychose zit vaak in de adolescentiefase, wat inhoudt dat rekening gehouden dient te worden met ontwikkelingsniveau, hetgeen uitgelegd wordt.
Abstract In this article we discuss the concept of staging of illness in relation to psychosis. In early detection of subclinical psychotic symptoms mostly a milder treatment like cognitive behavior therapy is sufficient; currently the effect of cognitive behavioral therapy on delaying or even preventing a psychosis is evaluated. Patients with an at risk mental state are mostly adolescents: this taking the developmental phase into account.

    ABSTRACT: The aim of this study was to investigate when social consequences in schizophrenia emerge, and what conditions give rise to the social disadvantage evident in people suffering from schizophrenia. Early course in schizophrenia was studied in a population-based sample of 232 first illness-episode cases retrospectively from onset to first admission, and in a representative subsample of 115 patients prospectively at six cross-sections over a period of 5 years. Data on non-specific and negative symptomatology and social development was compared with data from an age- and sex-matched control group drawn from the normal population. In total, 73% of the patients showed a prodromal phase of several years. First signs were depressive and negative symptoms. In 57% of cases social disability emerged 2 to 4 years before first admission. Social consequences depended on the level of social development at onset. An early onset involved social stagnation, and a late onset was associated with social decline. Men's poorer social outcome was determined by their lower level of social development at onset and socially adverse illness behaviour. The 5-year symptom-related course showed no gender difference. At 81% the lifetime prevalence of depressive mood until first admission was several times higher in schizophrenics than in healthy controls. Early depression predicted a lower subsequent score for affective flattening. Suicide indicators were predicted by lack of self-confidence and feelings of guilt early in the illness. Taking into account a prodromal phase of several years on average before first hospital admission, early detection, case identification and intervention are urgently needed. The intervention must be targeted at syndromes such as early depression, negative symptoms and certain forms of cognitive and social impairment.

    ABSTRACT: Intervention in the prodromal phase of schizophrenia and related psychoses may result in attenuation, delay or even prevention of the onset of psychosis in some individuals. However, a "prodrome" is difficult to recognise prospectively because of its nonspecific symptoms. This study set out to recruit and follow up subjects at high risk of transition to psychosis with the aim of examining the predictive power for psychosis onset of certain mental state and illness variables.Symptomatic individuals with either a family history of psychotic disorder, schizotypal personality disorder, subthreshold psychotic symptoms or brief transient psychotic symptoms were assessed and followed up monthly for 12 months or until psychosis onset. Twenty of 49 subjects (40.8%) developed a psychotic disorder within 12 months. Some highly significant predictors of psychosis were found: long duration of prodromal symptoms, poor functioning at intake, low-grade psychotic symptoms, depression and disorganization. Combining some predictive variables yielded a strategy for psychosis prediction with good sensitivity (86%), specificity (91%) positive predictive value (80%) and negative predictive value (94%) within 6 months. This study illustrates that it is possible to recruit and follow up individuals at ultra high risk of developing psychosis within a relatively brief follow-up period. Despite low numbers some highly significant predictors of psychosis were found. The findings support the development of more specific preventive strategies targeting the prodromal phase for some individuals at ultra high risk of schizophrenia.

    ABSTRACT: Diagnosis in psychiatry increasingly struggles to fulfil its key purposes, namely, to guide treatment and to predict outcome. The clinical staging model, widely used in clinical medicine yet virtually ignored in psychiatry, is proposed as a more refined form of diagnosis which could restore the utility of diagnosis, promote early intervention and also make more sense of the confusing array of biological research findings in psychiatry by organizing data into a coherent clinicopathological framework. A selective review of key papers in clinical medicine and psychiatry which describe clinical and clinicopathological staging, and a range of related issues. Clinical staging has immediate potential to improve the logic and timing of interventions in psychiatry just as it does in many complex and potentially serious medical disorders. Interventions could be evaluated in terms of their ability to prevent or delay progression from earlier to later stages of disorder, and they could be selected on clear-cut risk/benefit criteria. Biological variables and a range of candidate risk factors could be studied within and across stages, and their role, specificity and centrality in risk, onset and progression of disorder could be greatly clarified. A clinicopathological framework could be progressively constructed. Clinical staging with a restructure across and within diagnostic boundaries with the explicit operationalization of criteria for extent and progression of disorder should be actively explored in psychiatry as a heuristic strategy for the development and evaluation of earlier, safer, and more effective clinical interventions, and for clarifying the biological basis of psychiatric disorders.
