Abstract:
The article presents an analytical review aimed at determining the effect of anhedonia on the course and therapeutic prognosis of depression. Currently, there is no specific pharmacological approach to the treatment of anhedonia in depression.It is clear all antidepressants that affect the symptoms of depression in general act to a certain extent on anhedonia. Modern views on the biological mechanisms involved in the formation of anhedonia are described, on the basis of which a search for drugs with anti-anhedonic activity is possible. Vortioxetine can be considered as an antidepressant with a specific anti-anhedonic effect.

Abstract:
Since the introduction of DSM-III anhedonia has become a core depressive criterion and is defined as the loss of interest or pleasure. Although the origin of the word goes back to the end of the 19th century and numerous anhedonic symptoms are described in classic texts on depression, this centrality in the diagnosis of depression is only recent. Anhedonia is best described as a symptom complex with unclear boundaries cutting across the tripartite model of the mind (affect, volition, and cognition). Popular concepts of anhedonia pertain to the pleasure cycle and positive affectivity. These concepts partially overlap and are often mixed up, but clearly stem from different theoretical backgrounds: the affective science of reward processing versus more general, dimensional modelling of affect. The former concept seems more suitable to understand anhedonic emotions, the latter more suitable to understand anhedonic mood or trait. This narrative review covers the history of “anhedonia,” the different anhedonic phenomena, and psychopathological concepts. An attempt is made to go beyond a merely descriptive psychopathology. Neurobiological and psychological insights shed a light on how symptoms are made and interconnected; these insights possibly call for a new psychopathological language.

Abstract:
The article is written in the form of a survey lecture highlighting the modern views of scientists on the phenomenon of anhedonia. A comparative analysis of the traditional psychiatric view of anhedonia with the phenomenological one is carried out. The specificity of anhedonia as a psychopathological symptom and as a psychological phenomenon is shown, as well as the features of the manifestation of anhedonia in neurological diseases. For practicing psychiatrists, the aspect of differentiation of anhedonia may be important, allowing one to choose the most adequate ways of correcting it between psychotherapeutic interventions, prescribing antidepressants with a proven anti-anhedonic effect or atypical antipsychotics.

Abstract:
The aim of the study was to explore in depression the relationship between recent suicidal ideation and the different anhedonias taking into account the severity of depression. Recent studies have suggested that recent change of anhedonia and not state or trait anhedonia is associated with recent suicidal ideations even when the level of depression is controlled. Three samples were used (74 severe major depressives, 43 outpatients with somatic disorders presenting mild or moderate depression and 36 mild or moderate depressives hospitalized in the intensive coronary unit). Recent change of anhedonia was rated by the anhedonia subscale of the Beck Depression Inventory (BDI-II), state anhedonia by the Snaith–Hamilton Pleasure Scale (SHAPS), trait anhedonia by the TEPS (Temporal Experience of Pleasure Scale), musical anhedonia by the BMRQ (Barcelona Music Reward Questionnaire), social recent change of anhedonia by the SLIPS (Specific Loss of Interest and Pleasure Scale), the severity of depression by the BDI-II and the distinction between melancholic and non-melancholic was found using a subscale of the BDI-II. Bivariate and multivariate regression analyses were performed in each sample. In severe major depressives and, notably, in melancholia, recent suicidal ideation was associated with trait anhedonia; however, in mild or moderate depression, recent suicidal ideation was associated with recent change of anhedonia. Musical anhedonia and social recent change of anhedonia were not associated with recent suicidal ideation. Trait anhedonia could be, in severe depression, a strong predictor of recent suicidal ideation.

Abstract:
Anhedonia, the diminished ability to experience pleasure, is a key symptom of a range of mental and neurobiological disorders and is associated with altered eating behavior. This research study investigated the concept of anhedonia in relation to mental disorders and the perception of pleasure from food to better understand the link between anhedonia and eating behavior. A consumer survey (n = 1051), including the Food Pleasure Scale, the Chapman Revised Social Anhedonia Scale, the Patient Health Questionnaire, and the Generalized Anxiety Disorder scale, was conducted to explore the perception of pleasure from food among people with anhedonic traits. Comparative analyses were performed between people with symptoms of depression and/or anxiety and people with no symptoms of these conditions. A segmentation analysis was furthermore performed based on three levels of anhedonia: Low, Intermediate and High anhedonia. Thus, insights into how food choice and eating habits may be affected by different levels of anhedonia are provided for the first time. Our findings showed that the ‘Low anhedonia’ segment found pleasure in all aspects of food pleasure, except for the aspect ‘eating alone’. ‘Eating alone’ was, however, appreciated by the ‘Intermediate anhedonia’ and ‘High anhedonia’ segments. Both the ‘Intermediate anhedonia’ and ‘High anhedonia’ segments proved that their perceptions of food pleasure in general were affected by anhedonia, wherein the more complex aspects in particular, such as ‘product information’ and ‘physical sensation’, proved to be unrelated to food pleasure. For the ‘High anhedonia’ segment, the sensory modalities of food were also negatively associated with food pleasure, indicating that at this level of anhedonia the food itself is causing aversive sensations and expectations. Thus, valuable insights into the food pleasure profiles of people with different levels of anhedonia have been found for future research in the fields of mental illness, (food) anhedonia, and consumer behaviors.

Abstract:
Anhedonia stands as a core symptom and potential trait marker of major depressive disorder (MDD). The importance of rapid eye movement sleep latency (REML) as a biological marker of depression has previously and repeatedly been studied. The aim of this paper is to analyse the relationship between anhedonia and REML in moderately to severely depressed patients. The shortened Beck Depression Inventory (BDI-13) was chosen to assess depressive symptoms and, among them, more particularly, anhedonic symptoms. Two-way ANCOVA was used for statistical analyses. A significant association between anhedonic symptoms and REML was found when the number of sleep cycles (NCy) and the severity of depression were added as covariates. Our findings suggest that REML may be a useful variable to differentiate some diagnostic subtypes of depression related to anhedonia.

Abstract:
IntroductionGeneral-population studies investigating the biological correlates of anhedonia/amotivation might be informative for treatment breakthroughs for a number of clinical conditions. Reduced gut-microbial diversity might lead to an anhedonic/amotivational syndrome (“sickness behaviour”). However, how gut-microbial diversity contribute to this clinical phenotype is a key gap in knowledge. We hypothesised the endocannabinoid system would be at play.ObjectivesWe tested the hypothesis that the endocannabinoid system mediates the association between gut-microbial diversity and anhedonia/amotivationMethodsSecondary data analysis on 786 volunteer twins (TwinsUK). Measures of gut-microbiome, faecal endocannabinoid metabolites, and anhedonia/amotivation were collected over five years. To test our hypothesis we used a multilevel mediation model using alpha diversity as predictor, faecal levels of the endocannabinoid palmitoylethanolamide (PEA) as mediator, and anhedonia/amotivation as outcome. Analyses were adjusted for obesity, diet, antidepressants, and sociodemographic covariates.ResultsMean age was 65.2±7.6; 27% were obese and 4.7% were on antidepressants. Alpha diversity was significantly associated with anhedonia/amotivation (β=-0.37; 95%CI: -0.71 to -0.03; P=0.03). Faecal PEA levels mediated this association: the indirect effect was significant (β=-0.13; 95%CI: -0.24 to -0.01; P=0.03), as was the total effect (β=-0.38; 95%CI: -0.72 to -0.04; P=0.03). The direct effect of alpha diversity on anhedonia/amotivation was attenuated fullyConclusionsWe provided the first evidence showing that the association between gut-microbial features and anhedonia/amotivation is mediated by the endocannabinoid system. These findings shed light on a new therapeutic target in an area of unmet clinical need.DisclosureNo significant relationships.

Abstract:
AbstractThe capacity to sustain attention was explored in a sample of anhedonic subjects according to the Chapman physical anhedonia scale. Sustained attention was determined by studying task-induced changes over the duration of the Eriksen response competition task [Percept. Psychophys. 16 (1974) 143]. Anhedonic subjects had longer reaction times (RTs), but missed no more targets than control subjects. Anhedonic subject RTs got longer with time-on-task (TOT) and displayed greater intra-subject variability. These results confirm those of a previous study indicating that anhedonic subjects may have developed a more conservative response strategy [Psychophysiology 37 (2000) 711] and suggest that this strategy may result in a more rapid decrease in energetical resources. Moreover, the greater intra-subject variability demonstrates the importance of assessing performance over time and its relationship to the variability of responses in the cognitive performance of anhedonic subjects.

This study evaluated the accuracy and expressiveness of emotional communication by college students identified as anhedonic or control ( ns = 24), based on their scores on the Physical Anhedonia Scale, using an emotional communication task and self-report indices of emotional expressiveness and self-monitoring. As expected, the anhedonic group reported significantly less emotional expressiveness in real-life social situations.

Abstract:
Anhedonia is defined as the inability to gain pleasure from normally pleasurable experiences and reduced sexual desire. Rees et al. (2007) showed that limbic and paralimbic areas are responsible for sexual arousal and that anhedonia is associated with frontolimbic inhibition. In major depression, reduced ventral striatum and increased ventral prefrontal cortex areas was associated with anhedonia(Gorwood, 2009). Walter et al. (2009) indicated that there is a deviation in the neuronal activation pattern of the pregenual anterior cingulate cortex in anhedonic depression which is related to a glutamergic deficit. Glutamate was suggested to play a relevant role in reward system (Birgner et al., 2005). ACC is a key involved in affective state and glutamate mediates ACC activation to sexual attraction(Wu et al., 2009). Thus, a glutamatergic deficit might be related to reduced hedonic effect specific to major depression. Using an attention modulation of emotional and sexual pictures, we investigate the role of anhedonia on the ventral and dorsal systems in healthy volunteers and patients with major depression. They undergo an expectancy task in a 7 T scanner and passively view sexual and emotional photographs and are asked to expect either high salient pictures or high erotic pictures. Half of these pictures are announced by an expectancy cue, whereas the other half are preceded by a fixation cross. Snaith-Hamilton-Pleasure-Scale and Hamilton Depression Rating Scale are employed to assess anhedonia and depressive symptom severity. Brain metabolites in the dorsal and pgACC are measured using MRS. We will show how anhedonia modulates the neural response to sexual arousal.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Abstract:
Background: There is increasing theoretical interest in the idea that a greater tendency for the mind to wander may reduce positive emotion experience, with specific interest in clinical conditions such as depression that are characterised by reduced pleasure experience (anhedonia). However, it is unclear to what degree these claims are empirically supported. Objective: A systematic review was conducted to examine the evidence regarding the association between mind wandering and positive emotion experience. Method: The Cochrane library, MEDLINE, PsycINFO, and Web of Knowledge databases were searched. A narrative discussion considered both the pattern of findings and the methodological approaches utilised in this literature. Results: 879 studies were identified and 21 relevant papers were fully reviewed, consisting of cross-sectional, prospective and manipulation studies. Conclusions: Fourteen out of 15 cross-sectional studies supported the claim that increased mind wandering was related to decreased pleasure experience. One prospective study indicated that mind wandering generally preceded but was not subsequent to reductions in positive mood. There were six studies that manipulated mind wandering experimentally, four of which found that inducing greater mind wandering led to reduced positive affect and two of which found null results. Overall, this literature supports the claim that greater mind wandering is related to reduced positive affect. However, very few studies examined this relationship in the context of depression and therefore it remains to be established if these findings generalise to clinical populations. Empiricial Paper: Previous research has established that greater levels of mind wandering are associated with reduced positive affect (PA) in the general population. The present study aims to examine whether this mechanism may mediate the relationship between depression and reduced PA (anhedonia). A community sample (N = 69) with differing levels of depression severity took part. Using experience sampling methodology, we measured mind wandering and PA during everyday life and when completing a few scheduled positive activities. To examine if mind wandering specifically influenced PA or emotion experience more generally, we additionally measured levels of negative affect (NA). Across both contexts, both greater mind wandering and greater depression severity were independently associated with reduced PA and increased NA. Greater depression severity was associated with increasing levels of mind wandering in everyday life, but not during scheduled positive activities. Mind wandering did not mediate the link between depression and reduced PA/increased NA. Exploratory analyses did however reveal that a greater tendency for the mind wander to negative rather than positive themes did mediate the link between depression and reduced PA in everyday life. We replicated previous findings that increased mind wandering is related to reduced PA and increased NA but there was no evidence that this mediated the relationship between depression and altered affective experience. However, the greater tendency for the mind to wander to negative themes may mediate the link between depression and affect. If depression treatment approaches are to target mind wandering this suggests they should therefore focus on mind wandering valence in addition to extent.

Abstract:
Executive cognitive processes and emotion cue processing was explored in introvertive anhedonia, the O-LIFE’s negative schizotypal trait dimension, with the aim of identifying endophenotypes. The experimental work of the thesis was conducted in three distinct parts. The first two used reaction time tasks of selective attention to examine 1) the possibility of a general abnormality in executive cognitive functioning, and 2) the possibility of an emotion cue processing abnormality. Results from these two parts informed the development of the final experiment that used procedures adapted from animal associative learning to examine the interaction between executive cognitive processes and the processing of positive and negative emotional cues in 1) the learning of differentially reinforced biconditional discrimination and 2) the sensitivity to changes in the emotional valence of outcomes. Two experiments, presented in Chapter 2, established that introvertive anhedonia was associated with an executive functioning deficit that could be characterised as a deficiency in processing context. Chapter 3 presented a further three experiments indicating that introvertive anhedonia had blunted processing of negative and positive emotional cues, but under certain specific conditions a bias to the processing of negative stimuli. The final experiment, presented in Chapter 4, found that introvertive anhedonia was behaviourally insensitive to outcome valence changes of stimulus-outcome associations. The blunted processing of valenced stimuli seems to have influenced executive cognitive processes involved in both detecting the changes in outcome valence of associations and in forming new associations. An inability in introvertive anhedonia to adjust behaviour to changes in outcome valence might lead to perseveration, inappropriate responding and, in some situations, an over-exposure to aversive stimuli. The executive cognitive deficits observed in section two, and the emotion cue processing deficits observed in section three might therefore result form failures in common mechanisms.

Abstract:
The negative symptoms of schizophrenia, particularly anhedonia and amotivation, are associated with poor functioning and contribute to the chronicity of the illness. There are currently very few targeted interventions available for these difficulties. The Temporal Experience of Pleasure model suggests that there is a specific deficit in anticipatory pleasure in people with schizophrenia. However, studies in this field have produced conflicting results. The studies conducted had three broad aims. The first was to assess self-reported pleasure and its association with symptoms and mood. The second was to develop an experimental task that measured, for the first time, both anticipatory and consummatory pleasure using the same stimuli. This allowed a direct test of the hypothesis that there is a specific anticipatory pleasure deficit in people with schizophrenia. The final aim was to examine whether reduced anticipatory pleasure contributes to lower activity levels in everyday life. The results demonstrated that people with schizophrenia had comparable levels of anticipatory and consummatory pleasure to controls but a larger discrepancy between these ratings. Furthermore, anticipatory pleasure and expectation drive activity levels in the everyday life of control participants but these links were not present in people with schizophrenia. Positive affect was found to influence anticipatory pleasure across all three methodologies. These findings suggest that people with schizophrenia have difficulty translating anticipation into goal-directed activities. Positive mood may be an important contributor to anticipatory pleasure. The link between anticipation and activity may be an important therapeutic target for improvement in both negative symptoms and functional outcomes.

Abstract:
New insights have revealed the complex and heterogeneous nature of reward-related behaviours: not only are different aspects of reward (e.g. reward 'liking' and 'wanting') subserved by dissociable neural mechanisms, but they are differentially expressed across major psychiatric disorders. The aim of this thesis was to investigate discreet reward-related processes, pertaining to the hedonic and cognitive processing of rewards, in relation to schizophrenia and depression preclinical models. The Methylazoxymethanol acetate (MAM) neurodevelopmental model of schizophrenia and the Wistar Kyoto (WKY) inbred depression model were chosen based on their good face and construct validities to the clinical conditions. Microstructural analysis of licking in simple drinking and contrast situations were used to investigate the constructs of consummatory and anticipatory anhedonia in these models. Whilst MAM-treated rats showed no behaviours indicative of consummatory or anticipatory anhedonia, WKY rats showed generally lower consummatory and palatability responses to sweet solutions and failed to suppress their palatability responses to a contrasted solution (when a preferred solution was expected). Therefore, WKY rats demonstrated behaviours analogous to deficits in both consummatory and anticipatory aspects of hedonic processing. To investigate cognitive processing of rewards, outcome devaluation and differential outcome paradigms were adopted, but no impairments on either task were found for the MAM model. In contrast, WKY rats were insensitive to post-conditioning changes in reward value and did not benefit from stimulus-correlated outcomes during the acquisition of a conditional discrimination task. Therefore, WKY rats do not appear to use the nature and /or value of rewards to guide their behaviours in the same manner as controls. In short, MAM-treated animals did not display the hedonic deficits or impaired instrumental behaviours expected for a comprehensive schizophrenia model. In contrast, the WKY inbred rat strain appears to be suitable in investigating manifestations of clinical depression in respect to reward-processing deficits.

Memoria para optar al Título Profesional de Médico Veterinario
La anhedonia se describe como la disminución de la capacidad para sentir placer frente a diversas actividades, y se ha observado en humanos con ciertas patologías mentales. En otros mamíferos, como ratas y cerdos la anhedonia generada por estrés puede modificar el consumo de fuentes palatables como la sacarosa, cambiando sus preferencias. En el siguiente trabajo se estudió el efecto del estrés sobre la preferencia por sacarosa en perros. Se utilizaron 16 perros de 3–11 años, alojados en caniles, realizando pruebas de preferencia entre soluciones de sacarosa (10 g/L y 30 g/L) y agua durante 20 minutos, comparando las medias de consumo tras someter a la mitad de los animales a tres protocolos de bienestar: alimentación, paseo y enriquecimiento ambiental. Las pruebas previas a los protocolos experimentales arrojaron diferencias significativas en la preferencia según grupo etario, encontrándose mayor consumo de sacarosa 30 g/L y 40 g/L, con respecto a agua en perros adultos (≤6 años) (203,69 vs. 30,188 g. P=0,004 y 358,93 vs. 56,714 g. P=0,002), pero no en viejos (>6 años) (102,25 vs. 88,75 g. P=0,745 y 81,125 vs. 122,81 g. P=0,5), lo que podría deberse a la disminución en la percepción de los aromas en animales viejos. Sin embargo, no se observó efecto del estrés sobre las preferencias por sacarosa en ningún protocolo experimental, lo cual se condice con la alta variabilidad de resultados entre laboratorios. No obstante, esta conducta podría haberse observado con una menor variabilidad de factores intrínsecos y extrínsecos de los animales durante los ensayos, por lo que se recomiendan nuevos estudios complementarios para investigar la anhedonia en perros domésticos.

Abstract:
Depression is a highly debilitating illness for which there is currently sub-optimal treatment outcomes. Anhedonia (a loss of interest and pleasure) is a core symptom of depression that predicts poorer illness course and is currently not well repaired in psychological treatments. Acute and relapse prevention outcomes may be improved by clarifying which psychological mechanisms cause and maintain anhedonia, so that mechanisms can be systematically targeted in therapy. Mind wandering (a shift in contents of thoughts away from an ongoing task and/or events in the external environment to self-generated thoughts and feelings) has previously been linked to lower levels of happiness in the general population (e.g., Killingsworth & Gilbert, 2010). However, it has yet to be established if mind wandering relates to reduced positive affect in the context of depression. Therefore, the purpose of this thesis was to further explore the role of mind wandering in driving anhedonic symptoms. This thesis employed different research designs in order to establish if mind wandering is a causal mechanism driving anhedonia. Studies used a triangulation of measures to first establish correlational support (e.g. using self-report questionnaire measures, laboratory and real life positive mood inductions). Following this, studies aimed to examine if a causal relationship between mind wandering and positive affect exists by manipulating levels of mind wandering in the laboratory, real-world settings and using an empirically tested clinical intervention (Mindfulness Based Cognitive Therapy; MBCT). Using self-report measures of mindfulness and anhedonic symptoms, studies 1a and 1b found that the acting with awareness facet of mindfulness (a measure of trait mind wandering) was uniquely related to anhedonic depression symptoms in both a large community (n=440) and treatment-seeking previously depressed sample (n=409). These unique relationships remained significant when controlling for other facets of mindfulness and general depression symptoms. Study 2 (n=70) examined the relationship between mind wandering and reduced positive affect in both controlled laboratory and real world environments. Levels of mind wandering were found to be unrelated to emotional reactivity to positive laboratory mood induction tasks, but greater levels of mind wandering were significantly correlated with reduced happiness and increased sadness change to real world positive events. Next, two experimental studies were conducted on unselected samples which attempted to manipulate levels of mind wandering to observe the effect on emotional reactivity. In study 3 (n=90), a brief mindfulness manipulation of mind wandering proved unsuccessful, so it was not possible to determine how altering mind wandering impacted on positive reactivity. Analysis during the pre-manipulation mood induction revealed a significant correlation between greater spontaneous levels of mind wandering and lower self-reported happiness reactivity. In study 4 (n=95), participants followed audio prompts delivered via a smartphone application to manipulate mind wandering whilst completing everyday positive activities. This manipulation was successful but results revealed no significant condition differences in positive or negative emotional reactivity. Analysis during the pre-manipulation positive activity revealed greater mind wandering was trend correlated with reduced change in positive affect. A final empirical study (study 5; n=102) was designed to investigate the mediating role of mind wandering on the effect of MBCT on change in positive emotional experience. Recovered depressed participants undertaking MBCT were compared to recovered depressed participants in a no-intervention control group. Correlational analysis pre-intervention revealed no support for an association between mind wandering and positive reactivity to the mood induction tasks but mind wandering measured during everyday life (using experience sampling methodology; ESM) did relate to lower positive affect and higher negative affect. Participants in the MBCT group demonstrated a reduction in trait and ESM mind wandering, relative to participants in the control group. Furthermore, participants in the MBCT group demonstrated a significant decrease in anhedonic symptoms and increase in daily levels of positive affect. Change in trait mind wandering was found to mediate changes in self-reported anhedonic symptoms when controlling for change in other mindfulness facets, however change in ESM mind wandering did not mediate change in daily positive affect. MBCT also had no impact on emotional reactivity to positive mood induction tasks. Overall the findings from this thesis provide correlational support for the link between mind wandering and reduced positive affect in different testing environments. However, evidence of a causal relationship is currently limited. Consequently, a key recommendation from this thesis is to redirect attention to other driving mechanisms as targeting mind wandering in the treatment of anhedonic clients is unlikely to lead to large improvements. The theoretical, methodological and clinical implications of these findings are discussed along with suggestions for future research.

Abstract:
Flat affect (i.e., diminished expressivity) and self-reported anhedonia (i.e., lack of pleasure) are associated with many psychiatric disorders. There is a need to examine the relationship between specific anhedonia subtypes and flat affect in a non-clinical sample. Forty-seven undergraduate students (59% male; mean age 20.37; SD = 4.74) completed self-report questionnaires assessing four subtypes of anhedonia - consummatory/anticipatory by social/non-social. Participants then viewed 15 randomly-presented pictures (five neutral, ten negative) from the International Affective Pictures System while facial muscle activity (electromyography; EMG) was recorded. Male participants reporting a greater level of anhedonia, particularly consummatory social anhedonia, showed greater EMG activity change in the corrugator supercilii muscle to negative pictures, as compared with neutral pictures. Females showed the opposite pattern: more consummatory social anhedonia related to less EMG activity change in the corrugator muscle. In summary, consummatory social anhedonia in particular showed a strong relationship with facial expressivity that interacted with sex. In the presence of more consummatory social anhedonia, males show more negative facial reactions to negative stimuli while females show a more flattened affect. These findings may help explain discrepancies in existing research examining anhedonia and flat affect in clinical populations and have implications for etiology and treatments.
