The serotonergic system in mood disorders and suicidal behaviour.
A stress-diathesis explanatory model of suicidal behaviour has proved to be of heuristic value, and both clinical and neurobiological components can be integrated into such a model. A trait deficiency in serotonin input to the anterior cingulate and ventromedial prefrontal cortex is found in association with suicide, and more recently non-fatal suicidal behaviour, and is linked to decision-maki...
متن کاملSuicide and attempted suicide
Accurate prediction of suicide risk remains a challenge, in its prevention. Many people with psychiatric disorders do not manifest suicidal behaviour, suggesting the importance of diathesis, or susceptibility to suicide, in addition to associated disorders. At present there are no biomarkers to predict suicidal behaviour. The authors of this article have attempted to describe the neurobiology o...
متن کاملAssessing and managing suicidal behaviour in the primary care setting: A model for an integrated regional suicide prevention strategy.
Although suicide rates are decreasing in most countries, suicide is still a major health concern. Our aim was to introduce a complex, integrative, regional suicide prevention strategy. Based on reviewing the literature and on our previous studies we developed a suicide prevention model, which includes recognition, risk assessment and intervention. The main steps of the model are the recognition...
متن کاملProspective study of clinical predictors of suicidal acts after a major depressive episode in patients with major depressive disorder or bipolar disorder.
OBJECTIVE The authors investigated the predictive potential of a stress-diathesis model for suicidal behavior based on correlates of past suicidal acts. In this model, suicidal acts are precipitated by stressors such as life events or a major depressive episode in the setting of a propensity for acting on suicidal urges. This diathesis is expressed as the tendency to develop more pessimism in r...
متن کاملLoneliness and negative life events as predictors of hopelessness and suicidal behaviors in Hispanics: evidence for a diathesis-stress model.
In the present study, we examined loneliness and negative life events as predictors of suicide risk (viz., hopelessness and suicidal behaviors) in a sample of 160 Hispanic adults. Consistent with expectations, we found loneliness and negative life events to be positively associated with both hopelessness and suicidal behaviors. In addition, results of conducting hierarchical regression analyses...
