Overview

Anhedonia is defined as the inability to experience pleasure from activities usually found enjoyable, e.g. exercise, hobbies, music, sexual activities or social interactions. (/ˌænhiˈdniə/ Template:Respell; Greek: ἀν- an-, "without" + ἡδονή hēdonē, "pleasure"). While earlier definitions of anhedonia emphasized pleasurable experience, more recent models have highlighted the need to consider different aspects of enjoyable behavior, such as motivation or desire to engage in an activity ("motivational anhedonia"), as compared to the level of enjoyment of the activity itself ("consummatory anhedonia").[1] While anhedonia can be a feature of such mood changes, they are not mutually inclusive.

Anhedonia can be a characteristic of mental disorder including mood disorder, schizoaffective disorder, schizoid personality disorder and schizophrenia. For example, people affected with schizophrenia often describe themselves as feeling emotionally empty.[2] Mood disturbances are commonly observed in many psychiatric disorders, often precipitated by stressful life events and physical illness.[3]
