This latest research published in the journal, 'Neural correlates of specific musical anhedonia' reinforced the importance of neural connectivity in the reward response of human beings.
A's past history of depressive episodes, her recent increase in tearfulness and anhedonia, and her self-injurious behaviors.
Anhedonia might possibly accompany stress because the loss of the pleasure of aiming for a goal and achieving it (including defending oneself and escaping from a danger) could lead to immobility, and immobility offers the extreme chance of safety when an animal is facing the worst possible stressful situation--being seized by a predator--as in this case any movement can further stimulate the predator's aggressiveness.
According to Loas, the symptom of anhedonia appears as a potential inherent trait marker of MDD [3].
Interim results showed that all 15 randomized patients reported experiencing anhedonia as assessed by the Structured Clinical Interview for DSM Disorders (SCID-CT), and 14 of 15 patients reported having anhedonia of significant severity based on a study protocol-defined score of 5 or greater on the Snaith Hamilton Pleasure Scale (SHAPS).
Moreover, inflammation-associated change in total mood correlated with a reduction in connectivity between subgenual cingulate and bilateral nucleus accumbens, which is a dopamine-regulated reward-related region that is implicated in anhedonia. Interestingly, in females (but not males) exposed to endotoxin, increases in IL-6 were associated with increases in social pain-related neural activity (dorsal anterior cingulate cortex, anterior insula) that mediated the relationship between IL-6 increases and depressed mood increases (67).
Con base en el CDI la prevalencia global de sintomas depresivos fue del 20%, las prevalencias especificas fueron Anhedonia 40,9%, Ineficacia 35,2%, Animo negativo 17,0%, Problemas interpersonales 17,0% y Autoestima negativa 19,6%.
The distress levels related to feeling depressed /hopeless, feeling guilty, poor concentration, anhedonia, fatigue, suicidal ideation, and moving / speaking slowly were significantly and moderately correlated with overall functional impairment (r = 0.31-0.48, p < 0.001).
Self-Report Anhedonia Participants completed the Snaith-Hamilton Pleasure Scale (SHAPS; Snaith et al., 1995), a 14-item self-report measure that assesses the level of enjoyment obtained from various events or stimuli.
In more colloquial terms, one might experience a deficit in wanting (motivational anhedonia) or a deficit in liking (consummatory anhedonia).
Table 3 shows that all the patients had depressed mood while more than 80% had anhedonia, anorexia and insomnia.
