Hi, let's first understand mood disorder-Mood disorder is the term designating a group of diagnoses in the Diagnostic and Statistical Manual of Mental Disorders (DSM IV TR) classification system where a disturbance in the persons' mood is hypothesized to be the main underlying feature. The classification is known as mood (affective) disorders in ICD 10.  Two groups of mood disorders are broadly recognized; the division is based on whether the person has ever had a manic or hypomanic episode. Thus, there are depressive disorders, of which the best-known and most researched is major depressive disorder (MDD) commonly called clinical depression or major depression, and bipolar disorder (BD), formerly known as manic depression and characterized by intermittent episodes of mania or hypomania, usually interlaced with depressive episodes. However, there are also forms of depression of MDD and BD that are less severe and are known as dysthymia disorder(MDD) and cyclothymic disorder for (BD).  The Chat Doctor.
