Answer :
Anhedonia is a term that suggests a lack of caring or pleasure, and a reduction in a person's motivation or ability to engage in actions necessary to obtain a positive outcome.
The term "anhedonia" describes a diminished capacity for enjoyment. Since it was first documented in the previous century, it has played a significant role in many facets of psychopathology and continues to be a component of a number of mental diseases and maladaptive behaviours. Anhedonia has been researched the most in major depression, but a lot of literature has also been written about anhedonia in psychosis because it is an essential negative sign of schizophrenia.
