DefinitionBy Mayo Clinic staff
Dysthymia (dis-THIE-me-uh) is a mild but long-term (chronic) form of depression. Symptoms usually last for at least two years, and often for much longer than that. Dysthymia interferes with your ability to function and enjoy life.
With dysthymia, you may lose interest in normal daily activities, feel hopeless, lack productivity, and have low self-esteem and an overall feeling of inadequacy. People with dysthymia are often thought of as being overly critical, constantly complaining and incapable of having fun.
