Also known as Dysthymic disorder, Dysthymia is a type of less severe depressive mood disorder which is characterized by a lack of pleasure or energy in life. A single episode of this disorder usually continues for at least two years or even more, which is why it may also be misdiagnosed as severe chronic depression.

With a significant female predominance, Dysthymia is found to be common among individuals with a positive family history. Other causative factors may include genetics, abnormal brain functioning which involves emotions and thoughts, chronic stress, negative life events and poor coping capacities.

Patients with Dysthymia will often experience negative emotions, hopelessness, unexplained sadness, feeling of guilt, poor social skills, insomnia and sleepiness during the daytime, loss of appetite or increased appetite, weakness, lack of self-esteem and trouble in concentration. However, the diagnostic criteria for Dysthymia include a history of depressed mood on most of the days in a year for at least two years associated with at least two of the symptoms mentioned above.

As far as the modality of treatment for this condition is concerned, psychotherapy such as interpersonal therapy, cognitive behavioral therapy, etc. is indicated in most individuals with or without prescribing anti-depressants, depending on the severity of symptoms.
