Mood [affective] disorders
(F30-F39)
This block contains disorders in which the fundamental disturbance is a change in affect or
mood to depression (with or without associated anxiety) or to elation. The mood change is
usually accompanied by a change in the overall level of activity; most of the other
symptoms are either secondary to, or easily understood in the context of, the change in
mood and activity. Most of these disorders tend to be recurrent and the onset of individual
episodes can often be related to stressful events or situations.
F30
Manic episode
All the subdivisions of this category should be used only for a single episode.
Hypomanic or manic episodes in individuals who have had one or more previous
affective episodes (depressive, hypomanic, manic, or mixed) should be coded as
bipolar affective disorder (F31.-).
Includes: bipolar disorder, single manic episode
F30.0 Hypomania
A disorder characterized by a persistent mild elevation of mood, increased energy
and activity, and usually marked feelings of well-being and both physical and
mental efficiency. Increased sociability, talkativeness, over-familiarity, increased
sexual energy, and a decreased need for sleep are often present but not to the
extent that they lead to severe disruption of work or result in social rejection.
Irritability, conceit, and boorish behaviour may take the place of the more usual
euphoric sociability. The disturbances of mood and behaviour are not
accompanied by hallucinations or delusions.
