The 2017 CLEF eRisk pilot task focuses on automatically detecting depression as early as possible from a users' posts to Reddit. In this paper we present the techniques employed for the University of Arizona team's participation in this early risk detection shared task. We leveraged external information beyond the small training set, including a preexisting depression lexicon and concepts from ...

This prospective, randomized, blinded, controlled study compared outcomes in chronic, refractory major depressive disorder (MDD) with and without physicians’ prescribing medications guided by electroencephalography-based medication outcome prediction. There were statistically significant differences between the two groups in pretreatment vs. treatment Hamilton Depression Scale and Beck Depressi...

Suicide is a ubiquitous phenomenon present in every country, and a function of the constellation of multiple risk and protective factors. The relatively low occurrence of attempted and completed suicide in the general community makes its research and consequentially prediction and prevention difficult, however, suicide events are common among psychiatric patients who contact their general pract...

Whether defined as a symptom, a syndrome, a single disease, or a ' spectrum' of biopsychosocial manifestations, depression is at present the most common mental disorder in all the urbanizedindustrial societies and its frequency appears to be increasing in the developing countries. Klerman's observation that, after an 'age of anxiety', the world is entering an 'age of melancholy' (Klerman, 1978)...

Purpose: Depression causes dysfunction in various spheres of individual and social life, which is now considered as the fourth-leading cause of the global disease burden. Given that violence and aggression associated with depression in the community cause serious damage to the family, the prediction, early detection and effective treatment of aggressive and violent behavior are essential. The p...

CONTEXT Minimizing negative consequences of major depression following traumatic brain injury is an important public health objective. Identifying high-risk patients and referring them for treatment could reduce morbidity and loss of productivity. OBJECTIVE To develop a model for early screening of patients at risk for major depressive episode at 3 months after traumatic brain injury. DESIG...

OBJECTIVE This study was designed to examine predictors of psychopathology in non-clinically referred, sexually abused (SA) children, ages 6-16 years, 30-60 days following abuse disclosure and termination. METHOD Eighty SA children were administered a structured diagnostic interview and a variety of rating-scale instruments. Several forms of psychopathology were assessed, including posttrauma...

Neurophysiological deficits in the left dorsolateral prefrontal cortex (DLPFC) have been described in positron emission tomography studies of schizophrenia and depression. In schizophrenia and depression this deficit has been associated with the syndromes of psychomotor poverty and psychomotor retardation, respectively. Such findings lead to a prediction that DLPFC dysfunction is symptom rather...

BACKGROUND The function of basal ganglia (BG) in the pathophysiology of major depression (MD) is still unclear. Recent research found changes in BG regarding size, structure and cerebral perfusion in patients with MD. Neuroimaging shows recruitment of the striatum during feedback (FB) based incidental learning of probabilistic classification learning, while the medial temporal lobe (MTL) is ass...
