Depressive episode
In typical mild, moderate, or severe depressive episodes, the patient suffers from
lowering of mood, reduction of energy, and decrease in activity. Capacity for
enjoyment, interest, and concentration is reduced, and marked tiredness after
even minimum effort is common. Sleep is usually disturbed and appetite
diminished. Self-esteem and self-confidence are almost always reduced and, even
in the mild form, some ideas of guilt or worthlessness are often present. The
lowered mood varies little from day to day, is unresponsive to circumstances and
may be accompanied by so-called "somatic" symptoms, such as loss of interest
and pleasurable feelings, waking in the morning several hours before the usual
time, depression worst in the morning, marked psychomotor retardation,
agitation, loss of appetite, weight loss, and loss of libido. Depending upon the
number and severity of the symptoms, a depressive episode may be specified as
mild, moderate or severe.
