Reconsidering anhedonia in depression: Lessons from translational neuroscience

▶ Anhedonia includes motivational and consummatory aspects of reward processing. ▶ Current research often fails to discriminate between these two aspects. ▶ Preclinical data suggest that these two aspects are neurobiologically dissociable. ▶ Consequently, we propose motivational and consummatory anhedonia. ▶ We also introduce “decisional anhedonia” to address anhedonic effects on decisions.
