Nothing is more familiar to people than their moods and emotions. Oddly, however, it is not clear how these two kinds of affective processes are related. Intuitively, it makes sense that emotional reactions are stronger when they are congruent with a preexisting mood, an idea reinforced by contemporary emotion theory. Yet empirically, it is uncertain whether moods actually facilitate emotional ...

Background and Objective: Depression is one of the most prevalent mental disorders. Electroconvulsive Therapy (ECT) is one of the effective methods for treatment of depression. Regarding the stimulatory effect of glutaminergic system on the progression of depression, the effect of ketamine as one of the most important inhibitors of this system has been investigated on the effectiveness of ECT. ...

BACKGROUND Although inflammatory activity is known to play a role in depression, no work has examined whether experimentally induced systemic inflammation alters neural activity that is associated with anhedonia, a key diagnostic symptom of depression. To investigate this, we examined the effect of an experimental inflammatory challenge on the neural correlates of anhedonia-namely, reduced vent...

Background Depression is a mental health state whose frequency has been increasing in modern societies. It imposes a great burden, because of the strong impact on people’s quality of life and happiness. Depression can be reliably diagnosed and treated in primary care: if more people could get effective treatments earlier, the costs related to depression would be reversed. The aim of this study ...

BACKGROUND The Quality and Outcomes Framework in the United Kingdom (UK) National Health Service previously highlighted case finding of depression amongst patients with diabetes or coronary heart disease. However, depression in older people remains under-recognized. Comprehensive data for analyses of the association of depression in older age with other health and functional measures, and demog...

Although research has demonstrated a relationship between proinflammatory cytokine activity and depressive symptoms, the neurocognitive processes underlying this relationship have remained largely unexplored. Here, we examined the effect of proinflammatory cytokine activation on the neural correlates of socially painful experience and associated depressed mood. Participants received either low-...

Research in healthy controls has found that mood influences cognitive processing via level of action identification: happy moods are associated with global and abstract processing; sad moods are associated with local and concrete processing. However, this pattern seems inconsistent with the high level of abstract processing observed in depressed patients, leading Watkins (2008, 2010) to hypothe...

OBJECTIVES Mobile phones are commonly used by adolescents. The aim of this study was to clarify associations between duration of mobile phone use and psychological mood in high school students. METHODS This cross-sectional study included 2,785 high school students in Niigata, Japan. A self-administered questionnaire was used to elicit information on sex, school year, hours of mobile phone use...

The meanings of "anhedonia" and "depressed mood," the cardinal emotional symptoms of major depression, may be shaped by cultural norms regarding pleasure and sadness. Thirty-two European Americans, 26 Hispanic Americans, 33 Asian Americans, and 20 Russian Americans provided reports of (a) depressive symptoms, (b) momentary emotions and pleasure, and (c) global subjective well-being. Momentary r...

BACKGROUND False positives occur in approximately 11% of screening mammographies in the USA and may be associated with psychologic sequelae. METHODS We sought to examine the association of false-positive mammography with depressed mood among women in a screening population. Using data from a state-based mammography registry, women who completed a standardized questionnaire between 7 May 2001 ...
