What Is early-onset bipolar disorder and why are
we suddenly hearing so much about it?
Early-onset bipolar disorder is manic-depression that
appears early--very early--in life. For many years it was assumed
that children could not suffer the mood swings of mania or depression,
but researchers are now reporting that bipolar disorder (or early
temperamental features of it) can occur in very young children,
and that it is much more common that previously thought.
Is bipolar disorder in children the same thing
as bipolar disorder in adults?
Adults seem to experience abnormally intense moods
for weeks or months at a time, but children appear to experience
such rapid shifts of mood that they commonly cycle many times within
the day. This cycling pattern is called ultra-ultra rapid or ultradian
cycling and it is most often associated with low arousal states
in the mornings (these children find it almost impossible to get
up in the morning) followed by afternoons and evenings of increased
energy.
It is not uncommon for the first episode of early-onset
disorder to be a depressive one. But as clinical investigators have
followed the course of the disorder in children, they have reported
a significant rate of transition from depression into bipolar mood
states.
What are the symptoms in childhood, and how early
can they begin?
We have interviewed many parents who report that their
children seemed different from birth, or that they noticed that
something was wrong as early as 18 months. Their babies were often
extremely difficult to settle, rarely slept, experienced separation
anxiety, and seemed overly responsive to sensory stimulation.
In early childhood, the youngster may appear hyperactive,
inattentive, fidgety, easily frustrated and prone to terrible temper
tantrums (especially if the word "no" appears in the parental
vocabulary). These explosions can go on for prolonged periods of
time and the child can become quite aggressive or even violent.
(Rarely does the child show this side to the outside world.)
A child with bipolar disorder may be bossy, overbearing,
extremely oppositional, and have difficulty making transitions.
His or her mood can veer from morbid and hopeless to silly, giddy
and goofy within very short periods of time. Some children experience
social phobia, while others are extremely charismatic and risk-taking.
If the child is fidgety and inattentive and hyperactive,
isn't the correct diagnosis attention-deficit disorder with hyperactivity
(ADHD)? Or, if the child is oppositional, wouldn't oppositional-defiant
disorder (ODD) be the correct diagnosis?
Several studies have reported that over 80 percent
of children who have early-onset bipolar disorder will meet full
criteria for ADHD. It is possible that the disorders are co-morbid--appearing
together--or that ADHD-like symptoms are a part of the bipolar picture.
Also, the ADHD symptoms may simply appear first on the continuum
of a developing disorder.
Children with bipolar disorder exhibit much more irritability,
labile mood, grandiose behavior, and sleep disturbances-- often
accompanied by night terrors (nightmares filled with gore and life-threatening
content)--than do children with ADHD.
Because stimulant medications may exacerbate a bipolar
disorder and induce an episode or negatively influence the cycling
pattern of a bipolar disorder, bipolar disorder should be ruled
out first, before a stimulant is prescribed.
Almost all the children in our study of 120 boys and girls diagnosed
with bipolar disorder met criteria for oppositional defiant disorder
(ODD). Again, the child should be evaluated for a possible bipolar
disorder.
So how would a doctor diagnose early-onset bipolar
disorder?
The family history is an important clue in the diagnostic
process. If the family history reveals mood disorders or alcoholism
coming down one or both sides of the family tree, red flags should
appear in the mind of the diagnostician. The illness has a strong
genetic component, although it can skip a generation.
Many parents are told that the diagnosis cannot be
made until the child grows into the upper edges of adolescence--between
16 and 19 years old. The Diagnostic and Statistical Manual of Psychiatry--the
DSM-IV--uses the same criteria to diagnose bipolar disorder in children
as it does to diagnose the condition in adults, and requires that
the manic and depressive episodes last a certain number of days
or weeks. But as we already mentioned, the majority of bipolar children
experience a much more chronic, irritable course, with many shifts
of mood in a day, and often they will not meet the duration criteria
of the DSM-IV.
The DSM needs to be updated to reflect what the illness
looks like in childhood.
If a child hears voices or sees things, does that
mean he or she is schizophrenic?
Absolutely not. Psychotic symptoms such as delusions
(fixed, irrational beliefs) and hallucinations (seeing or hearing
things not seen or heard by others) can occur during both phases
of bipolar disorder. In fact, they are not uncommon. Sometimes the
voices and visions are compelling; often they are threatening. Quite
a few children report seeing bugs or snakes or say that they see
and hear satanic figures.
What are the treatments for early-onset bipolar
disorder?
The first line of treatment is to stabilize the child's
mood and to treat sleep disturbances and psychotic symptoms if present.
Once the child is stable, a therapy that helps him or her understand
the nature of the illness and how it affects his or her emotions
and behaviors is a critical component of a comprehensive treatment
plan.
Mood stabilizers are the mainstay of treatment for
a bipolar disorder, but many of these medications have only recently
begun to be used in children with the condition, so not a lot of
data about their use in childhood bipolar disorder exists. Many
psychiatrists are simply adapting what they know about the treatment
of adults to the pediatric and adolescent population. (However,
the anticonvulsant mood stabilizers such as Depakote and Tegretol,
etc. have been used to treat young children with epilepsy for quite
some time, so there is a literature about these drugs in the pediatric
population.)
Commonly prescribed mood stabilizers include lithium
carbonate (Lithobid, Lithane, Eskalith), divalproex sodium (Depakote,
Depakene), carbamazapine (Tegretol), and Oxcarbazapine (Trilepta).
Newer agents such as gabapentin (Neurontin), lamotrigine (Lamictal),
topirimate (Topomax), and tiagabine (Gabitril) are currently under
clinical investigation for the treatment of bipolar disorder and
are being used in children. (Lamictal is Black Label for those under
the age of 16.)
If a child is experiencing psychotic symptoms and/or
aggressive behavior, the newer antipsychotic drugs, risperidone
(Risperdal), olanzapine (Zyprexa), quetiapine (Seroquel), and Aripiprazole
(Abilify) are commonly prescribed. Older antipsychotics such as
thioridazine (Mellaril), haloperidol (Haldol), and molindone (Moban)
are old standbys. Clonazepam (Klonopin) and lorezapam (Ativan) are
also used to treat anxiety states, induce sleep, and put a break
on rapid-cycling swings in activity and energy.
Should antidepressants be used?
It's very risky. Several studies have reported high
rates of the induction of mania or hypomania and rapid-cycling in
children with bipolar disorder who are exposed to antidepressant
drugs of all classes. In addition, the child may experience a marked
increase in irritability and aggression. Many parents on the BPParents
listserv (an on-line community of parents who communicate with each
other from all over the world via E-mail) reported that their children
experienced psychosis and were hospitalized subsequent to their
treatment with antidepressants. Some children did well for weeks
or even for three months before a switch into mania and ultra-rapid
mood shifts began.
Can a child take antidepressants for the depressive
periods after he or she is stabilized on a mood stabilizer?
Maybe. Some children may be able to take an antidepressant
for a brief period if it is opposed by a mood stabilizer. More studies
need to be done so that treatment recommendations can be made.
