Mood Management.
A mood disorder is the term given for a group of diagnoses in
the Diagnostic and Statistical Manual of Mental Disorders (DSM IV TR)
classification system where a disturbance in the person's mood is hypothesized
to be the main underlying feature. The classification is known as mood
(affective) disorders in ICD 10.
English psychiatrist Henry Maudsley proposed an overarching category of
affective disorder. The term was then replaced by mood disorder, as the
latter term refers to the underlying or longitudinal emotional state, whereas
the former refers to the external expression observed by others.
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
described by intermittent periods of manic and depressed episodes.
