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.
The attachment theory suggests that adverse childhood experiences (ACEs) can have an effect on how individuals perceive other people's attitude towards them. ACEs have also been associated with adult depression. We hypothesised that ACEs associate with perceived negative attitude of others (AoO) and depressive symptoms (DEPS), and that these associations differ between the genders.
Altogether, 692 participants drawn from the general population completed the Trauma and Distress Scale, as a measurement of ACE and its domains: emotional abuse (EmoAb), physical abuse (PhyAb), sexual abuse (SexAb), emotional neglect (EmoNeg) and physical neglect (PhyNeg); a visual analog scale with the question: “What kind of attitude do other people take towards you?”, and the self-report scale DEPS on depressive symptoms.
ACEs, AoO and DEPS correlated strongly with each other. In path analyses, ACE total and all its domains associated directly and indirectly, via DEPS, to negative AoO in the whole sample, and in females separately. ACE total, EmoAb, PhyAb, EmoNeg and PhyNeg associated directly and indirectly, via AoO, to DEPS in the whole sample and in both genders separately. EmoNeg, in all, and EmoAB, in males, had specific associations both with negative AoO and DEPS. Mediation effect via AoO was greater than via DEPS.
ACEs have a direct and indirect, via depression, negative effect on how adult individuals perceive other people's attitude towards themselves. Additionally, negative AoO mediates the effects of ACEs on depression. Childhood EmoNeg associates specifically with negative AoO and DEPS in adulthood.
It is unclear whether there is a direct link between economic crises and changes in suicide rates.
The Lopez-Ibor Foundation launched an initiative to study the possible impact of the economic crisis on European suicide rates.
Data was gathered and analysed from 29 European countries and included the number of deaths by suicide in men and women, the unemployment rate, the gross domestic product (GDP) per capita, the annual economic growth rate and inflation.
There was a strong correlation between suicide rates and all economic indices except GPD per capita in men but only a correlation with unemployment in women. However, the increase in suicide rates occurred several months before the economic crisis emerged.
Overall, this study confirms a general relationship between the economic environment and suicide rates; however, it does not support there being a clear causal relationship between the current economic crisis and an increase in the suicide rate.
