PRACTICE
Depression and Disability
in Children and Adolescents
Eleanor
Guetzloe
For many years, depression and other disorders of mood were thought to be
afflictions of only adults. Within the past three decades, however, it has
become evident that mood disorders are common among children and adolescents.
Population studies reveal that between 10% and 15% of the child and adolescent
population exhibit some symptoms of depression (U. S. Department of Health and
Human Services [USDHHS], 2000).
In children and adolescents, the most frequently diagnosed mood disorders are
major depressive disorder, dysthymic disorder, and bipolar disorder. This digest
focuses on these three disorders as they are exhibited in childhood and
adolescence - their symptoms, causal factors, and treatment.
Major Depressive Disorder
Major depressive disorder is a serious condition characterized by one or more
major depressive episodes. In children and adolescents, an episode lasts an
average of seven to nine months (Birmaher et al., 1996a, 1996b). Depressed
children are sad and lose interest in activities they used to enjoy. They feel
unloved, pessimistic, or even hopeless; they think that life is not worth
living; and they may think about or threaten suicide. They are often irritable,
which may lead to disruptive or aggressive behavior. They may be indecisive,
have problems concentrating, and lack energy or motivation. They may neglect
appearance and hygiene, and their normal eating and sleeping patterns may be
disturbed (USDHHS, 2000).
Dysthymic
Disorder
Dysthymic disorder has fewer symptoms, but is more persistent. The child or
adolescent is depressed for most of the day on most days, and symptoms may
continue for several years, the average dysthymic period being approximately
four years. Seventy percent of children and adolescents with dysthymia
eventually experience an episode of major depression. When this combination of
major depression and dysthymia occurs, the condition is referred to as double
depression (USDHHS, 2000).
Bipolar
Disorder
In bipolar disorder, episodes of depression alternate with episodes of mania.
The depressive episode usually comes first, with the first manic features
becoming evident months or even years later. Adolescents with mania feel
energetic and confident; may have difficulty sleeping but do not tire; and talk
a great deal, often speaking very loudly or rapidly. They may complain of racing
thoughts. They may do schoolwork quickly and creatively, but in a chaotic,
disorganized way. In the manic stage, they may have exaggerated or even
delusional ideas about their capabilities and importance, become overconfident,
and be uninhibited with others. They may engage in reckless behavior (e. g.,
fast driving or unsafe sex). Sexual preoccupations are increased and may be
associated with promiscuous behavior (USDHHS, 2000).
Other
Disabilities Associated With Depressive Disorders
Approximately two-thirds of children and adolescents with major depressive
disorder also have another mental disorder, such as anxiety disorder, conduct
disorder, oppositional defiant disorder, psychoactive substance abuse or
dependence, or phobias (Anderson & McGee, 1994). Authorities have also noted
that children with medical problems often face extreme and/or chronic stress,
which places them at risk for depression. Estimates of depression among
youngsters with medical problems range from 7% in general medical patients to
23% in orthopedic patients (Guetzloe, 1991). Depression has also been linked to
a variety of other medical conditions, including endocrinopathies and metabolic
disorders (e.g., diabetes and hypoglycemia), viral infections (e.g., influenza,
viral hepatitis, and viral pneumonia), rheumatoid arthritis, cancer, central
nervous system disorders, metal intoxications, and disabling diseases of all
kinds. Some of these conditions may be temporary, but some may be diagnosed as
primary disabilities in youngsters with health impairments.
The Link
Between Depression and Suicide
A number of studies have confirmed that children and adolescents with depression
are at high risk for suicidal behavior (see Guetzloe, 1991). Because mood
disorders substantially increase the risk of suicide, suicidal behavior is a
matter of serious concern for parents, educators, and clinicians who deal with
the mental health problems of children and adolescents. Over 90% of children and
adolescents who commit suicide have a mental disorder (USDHHS, 2000).
Causal
Factors Related to Depression
The precise causes of depression are not known. Research on adults with
depression generally points to both biological and psychosocial factors, but
there has been considerably less research on children and adolescents (Kendler,
1995).
. Between 20% and 50% of
depressed children and adolescents have a family history of depression. It
is not clear whether the relationship between parent and childhood
depression derives from genetic factors or if depressed parents create an
environment in which children are more likely to develop mental disorders (USDHHS,
2000).
Biological factors . Biochemical and
physiological correlates of depression have been studied by medical
researchers, with results that generally point to a chemical imbalance in
the brain as a causal factor (Birmaher et al., 1996a,1996b). Most of these
studies have been conducted with adults, so the findings may not apply to
children and adolescents (Guetzloe, 1991).
Cognitive
factors . For several decades there has been
considerable interest in the relationship between a pessimistic mindset and
a predisposition to depression. Pessimistic individuals generally react more
passively, helplessly, and ineffectively to negative events than optimistic
individuals. The specific origins of pessimistic mindset have not been
established (USDHHS, 2000) but are topics of current research interest
(Alloy et al., 2001; Garber & Flynn, 2001).
Diagnosis
and Assessment of Depressive Illness in Young People
Recent research has focused on the development and validation of checklists and
protocols to be used by mental health professionals along with clinical
interviews and medical tests. An accurate diagnosis of depression is a complex
task, extremely difficult for even highly skilled physicians and other
clinicians. It requires a careful examination of physical, mental, emotional,
environmental, and cultural factors related to the child or adolescent, his/her
family, and the environment. Teachers, counselors, and other school personnel
are not expected to diagnose depression in young people; the major roles of
educators are to detect the symptoms of depression and make appropriate
referrals.
Treatment
of Depressive Disorders
Treatment approaches for children and adolescents include psychosocial
interventions (e. g., cognitive behavior therapy) and medication, as well as
traditional psychotherapy. Two forms of cognitive therapy (i.e., self-control
therapy for prepubertal children and coping skills for adolescents) have been
judged as probably effective (Kaslow & Thompson, 1998). A number of medications
are commonly prescribed for children and adolescents with depression, but many
of these have not yet been subjected to sufficient study. Effective treatment
requires intervention by both medical and mental health professionals, with
support from all others who come in contact with the young person; and is
therefore not within the purview of the school alone.
School and
Classroom Intervention
The educator's most important contribution is the provision of a positive and
supportive environment, components of which include satisfaction of basic needs,
caring relationships with adults, and physical and psychological security. Any
inclusion in a student's program that serves to enhance feelings of self-worth,
self-control, and optimism has the potential for ameliorating feelings of
depression. Aversive techniques (e. g., punishment and "get tough" approaches)
should be avoided to the extent possible (Guetzloe, 1989, 1991).
Educators must use instructional strategies that are both positive and effective
so that the student will achieve success and enjoy the learning process.
Examples include direct instruction with positive reinforcement, thematic
instructional units with varied levels of classroom assignments, learning
strategies (e. g., mnemonic devices) and utilization of the principles of
universal design for leaning, which promote access to the general curriculum for
students with learning problems. Some protective factors have been addressed in
published curricula (e. g., preventing alienation, enhancing self-esteem, and
learning self-control). Other interventions that have implications for school
programs (e. g., phototherapy and exercise) have been found to have value in
reducing symptoms of depression in adults (Brosse, Sheets, Lett, & Blumenthal,
2002; USDHHS, 2003), but have not yet been subjected to sufficient study with
children and adolescents.
Summary
Mood disorders, including major depression, dysthymia, and bipolar disorder, are
now recognized as serious problems among children and adolescents. This brief
discussion has focused on the symptoms of these disorders, their relationships
to other mental and physical problems, their treatment, and appropriate school
intervention.
