Reduced motivation and ability to experience pleasure, particularly from previously enjoyable activities
Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure.[1] While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning.[2][3][4] In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (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 previously pleasurable activities.[5][6] While the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) does not explicitly mention anhedonia, the depressive symptom analogous to anhedonia as described in the DSM-5 is a loss of interest or pleasure.[3]

However, there are two components to the positive affect experienced in rewarding situations - anticipatory positive affect (APA) and cunsummatory positive affect (CPA)...Berridge and Robinson [2] describe these constructs as 'wanting' and 'liking', respectively.
