Full Definition
Anhedonia is a fundamental symptom of depression characterized by a marked reduction in the ability to experience pleasure or interest in activities that were previously rewarding. It encompasses both the inability to anticipate pleasure (anticipatory anhedonia) and the inability to experience pleasure in the moment (consummatory anhedonia). Anhedonia is one of the two core symptoms required for diagnosing major depressive disorder, along with depressed mood. The symptom can also occur in other psychiatric conditions including schizophrenia, bipolar disorder, and substance use disorders. Neurobiologically, anhedonia is associated with dysfunction in the brain's reward pathways.
