Anhedonia is a major depressive disorder that results in an inability to gain pleasure from normally enjoyable experiences. It is a core symptom in depression and is also frequently seen in people suffering with bipolar depression, schizophrenia, substance-abuse disorders, Parkinson’s disease, diabetes and coronary artery disease. Anhedonia has been associated with changes in neurotransmitter levels involved in the brain’s reward system.
