(pubmedcentralcanada.ca)
• Empirical research on anhedonia was facilitated in the late 1970s and early 1980s by the development of clinical symptom rating scales 7 with acceptable levels of reliability and psychometrically sound self-report trait questionnaires 8 to assess decreases in the experience of pleasure in both schizophrenia patients and high-risk populations.

(frontiersin.org)

• A dimensional conceptualization posits that anhedonia severity is related to a transdiagnostic continuum of reward deficits in specific neural networks. (nih.gov)

Pleasurable3

• In the DSM-5, anhedonia is a component of depressive disorders, substance-related disorders, psychotic disorders, and personality disorders, where it is defined by either a reduced ability to experience pleasure, or a diminished interest in engaging in pleasurable activities. (wikipedia.org)
• We repeatedly sampled pleasurable experiences within individuals' daily lives by means of Experience Sampling Methods, and compared how positive affect unfolded in the daily life of healthy controls versus patients diagnosed with MDD and anhedonia. (springer.com)
• This study will help determine whether adolescents who have the psychological trait of anhedonia (i.e., the tendency to not enjoy or be interested in pleasurable activities) are at greater risk for using alcohol, drugs, and tobacco during high school. (grantome.com)

Reduced motivation1

• Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. (wikipedia.org)

Aspects of anhedonia2

• In PTSD patients, scales measuring these symptoms correlate strongly with scales that measure more traditional aspects of anhedonia, supporting this association. (wikipedia.org)
• However, several aspects of anhedonia are poorly represented within the repertoire of current preclinical assessments. (frontiersin.org)

Symptoms of Anhedonia1

• There is a critical need for a validated treatment that specifically targets anhedonia, and this project will evaluate the effects of this new treatment on anhedonia and will establish how this treatment impacts brain systems that mediate reward processing, clinical symptoms of anhedonia, functional outcomes, and behavioral indices of reward processing. (clinicaltrials.gov)

Signature of anhedonia1

• Our results suggest that the dynamical signature of anhedonia in MDD can be described best as a lower average level of PA, and "normal" in terms of PA dynamics, daily reward reactivity and reward recovery. (springer.com)

Assessment of anhedonia1

• Finally, we provide recommendations for optimal assessment of anhedonia in treatment studies that are aimed at ameliorating anhedonia and other negative symptoms. (pubmedcentralcanada.ca)

Children with anhedonia5

• Researchers have identified changes in brain connectivity and brain activity during rest and reward anticipation in children with anhedonia, a condition where people lose interest and pleasure in activities they used to enjoy. (news-medical.net)
• Analysis of brain connectivity at rest revealed significant differences in children with anhedonia compared to children without anhedonia. (news-medical.net)
• These findings suggest that children with anhedonia have altered integration of reward and arousal compared to children without anhedonia. (news-medical.net)

• The study suggests that children with anhedonia have differences in the way their brain integrates reward and arousal and in the way their brain activates when anticipating rewards. (news-medical.net)

Contribute to anhedonia1

• While researchers have sought to understand the brain mechanisms that contribute to anhedonia, investigations on this condition have more commonly focused on adults rather than children. (news-medical.net)

PDOD5

Clinical3

• Studies in clinical populations, healthy populations, and animal models have implicated a number of neurobiological substrates in anhedonia. (wikipedia.org)
• Through the use of these various assessment strategies, a considerable body of research has amassed that attests to the clinical significance of anhedonia and its role within the broader construct of negative symptoms. (pubmedcentralcanada.ca)
• In clinical practice, anhedonia is defined as a "markedly diminished interest or pleasure in all, or almost all, activities of the day" [ 1 ], suggesting pleasure experiences in anhedonia are flat and blunted. (springer.com)

Anhedonic1

• We documented associations between blood KP neurotoxins and striatal choline (membrane turnover marker) levels along with decreased anterior cingulate cortex (ACC) 3- aminobutyric acid (GABA) levels in anhedonic MDD adolescents, which were correlated with anhedonia scores in the whole MDD group. (grantome.com)

High anhedonia1

• Once use is initiated, high-anhedonia individuals may be more sensitive to the acute subjective rewarding effects of drugs, which may further devalue the relative salience of non-drug rewards and result in declining engagement in alternative reinforces. (grantome.com)
