Anhedonia is a personality trait associated with a decrease in the ability to feel pleasure. We investigated the experience of pleasure in individuals with physical and social anhedonia for positive pictures with varying levels of luminance contrast. Photographs with either a sensory or a social content were modified with a contrast-gradation procedure. Participants had to report the intensity ...

Anhedonia, the lack of pleasure, has been shown to be a critical feature of a range of psychiatric disorders. Yet, it is currently measured primarily through subjective self-reports and as such has been difficult to submit to rigorous scientific analysis. New insights from affective neuroscience hold considerable promise in improving our understanding of anhedonia and for providing useful objec...

BACKGROUND Depression has been associated with increased all-cause mortality in people with type 2 diabetes. AIMS To test whether anhedonia, dysphoria and anxiety are differentially associated with all-cause mortality and examine symptom-specific behavioural or pathophysiological mechanisms. METHOD A total of 1465 people completed the Edinburgh Postnatal Depression Scale in 2005 and were fo...

This longitudinal study investigates whether anhedonia and pessimistic attributional style represent a clinical state or a trait in hospitalized depressed adolescents. 81 consecutive adolescent inpatients were screened with the Beck Depression Inventory (BDI) and the clinician-rated Major Depressive Disorder (MDD) criteria sheet. 51 patients with BDI score ≥10 and/or ≥4 symptoms on MDD criteria...

Anhedonia, the decreased capacity to experience pleasure, is a defining symptom of unipolar major depressive disorder (MDD). This review summarizes definitions and measurement issues related to the assessment of hedonic capacity in MDD, epidemiological research addressing linkages between anhedonia and MDD, as well as biomedical research investigating the neurobiology of anhedonia in both pre-c...

BACKGROUND The relationships between anhedonia and suicidal ideation or suicide attempts were explored in a large sample of physicians using the interpersonal psychological theory of suicide. We tested two hypotheses: firstly, that there is a significant relationship between anhedonia and suicidality and, secondly, that anhedonia could mediate the relationships between suicidal ideation or suic...

BACKGROUND Emotional impairments such as anhedonia are often considered key features of schizophrenia. However, self-report research suggests that emotional experience in response to affect-eliciting stimuli is intact in schizophrenia. Investigation of neural activity during emotional experience may help clarify whether symptoms of anhedonia more likely reflect alterations of in-the-moment hedo...

Social anhedonia is a promising indicator for the vulnerability towards developing schizophrenia-spectrum disorders and is an important determinant of the social impairment associated with these disorders. It is unknown if social anhedonia is associated with true deficits in experiential reactions or if lower social functioning in social anhedonia reflects behavioral deficits in social skill or...

Anhedonia is a condition in which the capacity of experiencing pleasure is totally or partially lost, and it refers to both a state symptom in various psychiatric disorders and a personality trait. It has a putative neural substrate, originating in the dopaminergic mesolimbic and mesocortical reward circuit. Anhedonia frequently occurs in mood disorders, as a negative symptom in schizophrenia, ...

BACKGROUND The disorganized and negative dimensions of schizotypy are characterized by cognitive disorganization and anhedonia, respectively. The aim of the study was to investigate the relationships between these two dimensions of schizotypy by taking into account ambivalence and the distinction between consummatory and anticipatory anhedonia. METHODS Dimensional analysis and categorical ana...
