The aim of the current study was to explore the effect of gender, age at onset, and duration on the long-term course of schizophrenia.
Twenty-nine centers from 25 countries representing all continents participated in the study that included 2358 patients aged 37.21 ± 11.87 years with a DSM-IV or DSM-5 diagnosis of schizophrenia; the Positive and Negative Syndrome Scale as well as relevant clinicodemographic data were gathered. Analysis of variance and analysis of covariance were used, and the methodology corrected for the presence of potentially confounding effects.
There was a 3-year later age at onset for females (P < .001) and lower rates of negative symptoms (P < .01) and higher depression/anxiety measures (P < .05) at some stages. The age at onset manifested a distribution with a single peak for both genders with a tendency of patients with younger onset having slower advancement through illness stages (P = .001). No significant effects were found concerning duration of illness.
Our results confirmed a later onset and a possibly more benign course and outcome in females. Age at onset manifested a single peak in both genders, and surprisingly, earlier onset was related to a slower progression of the illness. No effect of duration has been detected. These results are partially in accord with the literature, but they also differ as a consequence of the different starting point of our methodology (a novel staging model), which in our opinion precluded the impact of confounding effects. Future research should focus on the therapeutic policy and implications of these results in more representative samples.
The aim of the current study was to explore the changing interrelationships among clinical variables through the stages of schizophrenia in order to assemble a comprehensive and meaningful disease model.
Twenty-nine centers from 25 countries participated and included 2358 patients aged 37.21 ± 11.87 years with schizophrenia. Multiple linear regression analysis and visual inspection of plots were performed.
The results suggest that with progression stages, there are changing correlations among Positive and Negative Syndrome Scale factors at each stage and each factor correlates with all the others in that particular stage, in which this factor is dominant. This internal structure further supports the validity of an already proposed four stages model, with positive symptoms dominating the first stage, excitement/hostility the second, depression the third, and neurocognitive decline the last stage.
The current study investigated the mental organization and functioning in patients with schizophrenia in relation to different stages of illness progression. It revealed two distinct “cores” of schizophrenia, the “Positive” and the “Negative,” while neurocognitive decline escalates during the later stages. Future research should focus on the therapeutic implications of such a model. Stopping the progress of the illness could demand to stop the succession of stages. This could be achieved not only by both halting the triggering effect of positive and negative symptoms, but also by stopping the sensitization effect on the neural pathways responsible for the development of hostility, excitement, anxiety, and depression as well as the deleterious effect on neural networks responsible for neurocognition.
Background: Involuntary psychiatric admission is a controversial issue with legislation varying from country to country. Research on elderly individuals being involuntary admitted has been limited. This study aims first at assessing whether elderly involuntary admitted patients (IAPs) differ with regard to demographic, psychopathological, and behavioral characteristics from voluntary admitted psychiatric patients (VAPs) and second to assess whether the former group should be treated in a different (special) way.
Methods: Forty IAPs were compared to 39 VAPs with regard to sociodemographic data, DSM-IV diagnosis, as well as behavioral issues recorded by the Patient–Staff Conflict Checklist – Shift Report (PSCC-SR). All patients were aged 60 years and over and were admitted in the psychiatric departments of four general hospitals in Athens. The study period lasted 12 months.
Results: VAPs were more likely to be suffering from mood disorders, while IAPs presented higher rates of delirium. From the 20 items of the PSCC-SR, differences were found only in two: IAPs presented more aggressive behavior during the first few days of admission whereas VAPs had committed recent suicide attempt just before admission.
Conclusion: From the clinical point of view, IAPs presented with delirium and more aggressive behavior, whereas, the VAPs presented with higher rates of mood disorder and suicidality. However, from the medicolegal point of view, our findings lend support to the argument of either setting a limited time frame for involuntary admission in elderly patients, and/or allowing for elderly individuals with acute organic conditions to be treated against their will.
The initiative of the Royal College of Psychiatrists to establish international divisions has created considerable enthusiasm. College members have some common characteristics, mainly their training and success in the Royal College examination. Thus College members share a common approach to the practice of psychiatry as well as some common experiences; it can be argued that they share a common language in psychiatry.
