Anhedonia 2012-09-20T06:51:36Z Loss of interest in pleasurable activities Anhedonic HP:0012154 Loss of ability to enjoy things Loss of enjoyment Inability to experience pleasure Decreased ability or inability to experience, feel, or anticipate pleasure from activities, experiences, or stimuli that are typically found pleasurable by the individual. This may involve diminished enjoyment of previously rewarding experiences (e.g., hobbies, social interactions, or sexual activity) or reduced pleasure in response to stimuli processed through the senses (e.g., music, food, or tactile contact). Anhedonia is a disruption in the capacity to derive emotional reward and is not due to primary sensory deficits or medical conditions (e.g., anosmia from viral illness). The phenomenon involves altered affective processing rather than impaired sensory perception.
