Overview of Mental Disorders in Children
Depression and Suicide in Children and Adolescents
In children and adolescents, the most frequently diagnosed
mood disorders are major depressive disorder, dysthymic disorder, and bipolar
disorder. Because mood disorders such as depression substantially increase the
risk of suicide, suicidal behavior is a matter of serious concern for clinicians
who deal with the mental health problems of children and adolescents. The
incidence of suicide attempts reaches a peak during the midadolescent years, and
mortality from suicide, which increases steadily through the teens, is the third
leading cause of death at that age (CDC, 1999; Hoyert et al., 1999). Although
suicide cannot be defined as a mental disorder, the various risk
factors—especially the presence of mood disorders—that predispose young people
to such behavior are given special emphasis in this section, as is a discussion
of the effectiveness of various forms of treatment. The evidence is strong that
over 90 percent of children and adolescents who commit suicide have a mental
disorder, as explained later in this section.
Major depressive disorder is a serious condition characterized by one or more
major depressive episodes. In children and adolescents, an episode lasts on
average from 7 to 9 months (Birmaher et al., 1996a, 1996b) and has many clinical
features similar to those in adults. Depressed children are sad, they lose
interest in activities that used to please them, and they criticize themselves
and feel that others criticize them. They feel unloved, pessimistic, or even
hopeless about the future; they think that life is not worth living, and
thoughts of suicide may be present. Depressed children and adolescents are often
irritable, and their irritability may lead to aggressive behavior. They are
indecisive, have problems concentrating, and may lack energy or motivation; they
may neglect their appearance and hygiene; and their normal sleep patterns are
disturbed (DSM-IV).
Despite some similarities, childhood depression differs in important ways from
adult depression. Psychotic features do not occur as often in depressed children
and adolescents, and when they occur, auditory hallucinations are more common
than delusions (Ryan et al., 1987; Birmaher et al., 1996a, 1996b). Associated
anxiety symptoms, such as fears of separation or reluctance to meet people, and
somatic symptoms, such as general aches and pains, stomachaches, and headaches,
are more common in depressed children and adolescents than in adults with
depression (Kolvin et al., 1991; Birmaher et al., 1996a, 1996b).
Dysthymic disorder is a mood disorder like major depressive disorder, but it has
fewer symptoms and is more chronic. Because of its persistent nature, the
disorder is especially likely to interfere with normal adjustment. The onset of
dysthymic disorder (also called dysthymia) is usually in childhood or
adolescence (Akiskal, 1983; Klein et al., 1997). The child or adolescent is
depressed for most of the day, on most days, and symptoms continue for several
years. The average duration of a dysthymic period in children and adolescents is
about 4 years (Kovacs et al., 1997a). Sometimes children are depressed for so
long that they do not recognize their mood as out of the ordinary and thus may
not complain of feeling depressed. Seventy percent of children and adolescents
with dysthymia eventually experience an episode of major depression6 (Kovacs et
al., 1994). When a combination of major depression and dysthymia occurs, the
condition is referred to as double depression.
Bipolar disorder is a mood disorder in which episodes of mania alternate with
episodes of depression. Frequently, the condition begins in adolescence. The
first manifestation of bipolar illness is usually a depressive episode. The
first manic features may not occur for months or even years thereafter, or may
occur either during the first depressive illness or later, after a symptom-free
period (Strober et al., 1995).
The clinical problems of mania are very different from those of depression.
Adolescents with mania or hypomania feel energetic, confident, and special; they
usually have difficulty sleeping but do not tire; and they talk a great deal,
often speaking very rapidly or loudly. They may complain that their thoughts are
racing. They may do schoolwork quickly and creatively but in a disorganized,
chaotic fashion. When manic, adolescents may have exaggerated or even delusional
ideas about their capabilities and importance, may become overconfident, and may
be“fresh” and uninhibited with others; they start numerous projects that they do
not finish and may engage in reckless or risky behavior, such as fast driving or
unsafe sex. Sexual preoccupations are increased and may be associated with
promiscuous behavior.
Reactive depression, also known as adjustment disorder with depressed mood, is
the most common form of mood problem in children and adolescents. In children
suffering from reactive depression, depressed feelings are short-lived and
usually occur in response to some adverse experience, such as a rejection, a
slight, a letdown, or a loss. In contrast, children may feel sad or lethargic
and appear preoccupied for periods as short as a few hours or as long as 2
weeks. However, mood improves with a change in activity or an interesting or
pleasant event. These transient mood swings in reaction to minor environmental
adversities are not regarded as a form of mental disorder.
