What is schizophrenia?
Schizophrenia
is a major psychiatric illness. Symptoms usually begin in late adolescence or
early adulthood. Numerous studies have found that about 1 in every 100 people
around the world has the disorder. However, schizophrenia with an onset in
adolescence (prior to age 18) is less common, and an onset of the disorder in
childhood (before age 13) is exceedingly rare. It is thought that at most one
in every 100 adults with schizophrenia develops it in childhood.
Symptoms and Diagnosis
In both
adults and children, the symptoms of schizophrenia can be divided into two
broad categories--positive symptoms and negative symptoms.
+ Positive symptoms
include: hallucinations, usually voices which are critical or threatening;
delusions, which are firm beliefs that are out of touch with reality and which
commonly include the fear that people are watching, harassing, or plotting
against the individual; disorganized speech, which is often seen as an
inability to maintain a conversation, usually as a result of difficulty staying
on topic; or, disorganized or catatonic behavior, which can include behavior
that is unusual and bizarre, or can be demonstrated by difficulty planning and
completing activities in an organized fashion.
+ Negative symptoms
include: reduction in emotional expression; lack of motivation and energy; or,
loss of enjoyment and interest in activities, including social interaction.
Schizophrenia
is diagnosed by the presence of two of the symptoms described above. For a
diagnosis of schizophrenia, two of these symptoms must be present for at least
6 months and must be accompanied by increased difficulty in daily living in
areas such as school, friendships, and self-care.
Hallucinations or delusions in a child
should lead to an evaluation by a mental health professional who
has experience working with children and adolescents with mental health
disorders. A diagnosis of schizophrenia is made through an interview with the
child and parents using information obtained from them and from school
personnel.
Difficulties in diagnosing schizophrenia
Many of the
symptoms seen in people with schizophrenia are also found in people with
depression, bipolar disorder, or other illnesses. As a result, studies have
found that misdiagnosis is common. This is particularly true with children and
adolescents. As such, it is extremely important to rule-out other diagnoses
such as depression, bipolar disorder, and substance use before making a
diagnosis of schizophrenia.
An additional difficulty in making a
diagnosis in children and adolescents relates to the fact that hallucinations
are surprisingly common and, in fact, are most often seen in children and
adolescents with diagnoses other than schizophrenia. In a large study at the National Institutes of Health, the great majority of
those previously diagnosed with schizophrenia did not receive that diagnosis
following careful evaluation. In many children with other conditions, the
nature of the hallucinations is different. While
hallucinations in people with schizophrenia are often pervasive when not well
treated, many children with other conditions such as mood disorders and
dissociative disorders, report auditory hallucinations when they are under
stress. These hallucinations tend to be brief and very intermittent
(lasting for only a few minutes). Also, children are very susceptible to
leading questions and therefore should be asked about symptoms in a neutral
fashion (i.e., not “Do you hear voices?”).
Children
with pervasive developmental disorders (autism, Asperger’s disorder, or an
unspecified pervasive developmental disorder) often have social difficulties,
disorganized behavior and language impairments. These developmental disorders
can be confused with a diagnosis of schizophrenia.
Prognosis of early onset schizophrenia
The outcome
for children with schizophrenia varies greatly and some individuals function
well with medication. Earlier onset is often associated with a poorer outcome
when it interferes with attending school and completing an education. However,
because children typically live at home with the combined social environments
of family and school, symptoms are often recognized early. This fact is
significant because recent studies have suggested that earlier treatment may
reduce the decline in functioning and long-term impairments commonly associated
with schizophrenia. As such, accurate and early intervention and diagnosis are
critical
Treatment for schizophrenia
Treatment
for schizophrenia includes biological, educational, and social interventions.
Medication is the cornerstone of the treatment of schizophrenia, but should be
viewed as a means to facilitate psychological and social interventions.
Treatment with only medication is not as effective as medication therapy
combined with other forms of treatment.
The medications used to treat
schizophrenia are termed “antipsychotics” or “neuroleptics”. Although these
medications are often effective, they have been associated with significant
side effects. The last decade has seen the introduction of a number of new anti-psychotics
with reduced side effects. The most commonly used medications now are:
risperidone (Risperdal), olanzapine (Zyprexa), and quetiapine (Seroquel).
Older, rarely used medications include haloperidol (Haldol), thioridazine
(Mellaril), and chlorpromazine (Thorazine). For individuals who are not
responsive to these medications, clozapine (Clozaril) is an important option,
but is not used as a first treatment due to significant side-effects (see
below). It is also important that associate symptoms be recognized and treated
appropriately. For example, individuals with schizophrenia who develop
depression or anxiety should be treated for these symptoms.
Children and adolescents with
schizophrenia often need adjustments to their educational programs. Typically
this would include smaller classrooms with teachers who are experienced with
children and adolescents with psychiatric disorders. Their academic work may
also need to be modified in order to accommodate problems sometimes associated
with schizophrenia such as reduced concentration and attention.
Social
difficulties are commonly seen with early onset schizophrenia. These include
difficulty making and keeping friends, difficulty with interpersonal
interactions, and low frustration tolerance. Activities to
develop social skills is integral to the treatment of schizophrenia. In
addition, family therapy and education about schizophrenia may help family
members to cope with the child’s illness.
Common side effects of antipsychotic medications
Every youth
will have a different reaction to any medication--be it an antibiotic or an
antipsychotic. Nonetheless, the most common problem that children and
adolescents report when taking the new generation of antipsychotic medications (olanzapine
and risperidone, for example) is weight gain. This can be problematic because
teens are particularly sensitive about how they look. Youths should be encouraged to eat a healthy
diet and to exercise regularly to minimize the weight gain as much as possible.
Common side effects of the older class of
antipsychotics, such as the more commonly-use, less expensive, haloperidol
(Haldol), thioridazine (Mellaril), and chlorpromazine (Thorazine) include
drowsiness, dry-mouth and neurological side effects which need medical attention.
A medication used when other
antipsychotics have not been effective is clozapine (Clozaril). For persons taking clozapine (Clozaril)
regular monitoring of blood levels is essential because approximately 1% of those taking
clozapine (Clozaril) will develop a serious side-effect (agranulocytosis).
Research and new treatments
Much
research and development of new medications for schizophrenia is underway. Some
promising medications have very different mechanisms of action and so may be
more effective with fewer side effects. However, the process of drug
development and approval is slow and many of these medications are only
currently available in research studies. Several centers around the country are
involved in research with these new medications.
