Anhedonia Latest Facts: Causes, Types, Diagnosis and Treatment

A person who develops anhedonia loses interest in activities which they used to appreciate before like riding bicycles, cooking, dancing, and hugging. The activities which once used to be enjoyable are no longer enjoyed in anhedonia. This may be a sign of major depressive disorder, but it could also be a manifestation of different mental health conditions. Many people who have anhedonia don’t necessarily have an underlying mental disease.
