THE EPILEPSY REPORT OCTOBER 2008
I
f you are reading this article, I
assume that you are having problems
with seizures or problems with side
effects of medication. Take heart. You
may feel like you are at the end of your
rope, but most likely you are only at
the end of your knowledge. In epilepsy,
knowledge is power – and seizure
control.
In this article I am going to help you
understand what epilepsy is and how it
is diagnosed. The successful treatment
of epilepsy depends upon an accurate
diagnosis. You may be surprised to
discover that for most children that
diagnosis depends upon you.
I am sure you already know that
epilepsy is more than just a medical
diagnosis. Epilepsy affects the entire
family. It affects the child’s development,
social skills, and school performance.
Here I will cover the basics, but you
will find that understanding the basics
can be very powerful in giving you
more control and giving you back your
family’s life.
The goal of treatment
The goal of epilepsy treatment is
very simple: NO SEIZURES and NO
SIDE EFFECTS. That’s it. In recent
years, I have heard more complaints
about medication side effects than I have
about seizures (though I do hear plenty
about seizures.) Treatment should not
be part of the problem. Unfortunately,
I have also discovered parents often
do not bring up problems with side
effects to the physician – or they barely
mention them. Remember the physician
does not live with you. If you do not
provide full and detailed reports of the
problems you are having, even the most
expert doctor can’t make it better. Trust
your own sense if you feel your child
is overmedicated – and back it up with
the clearest description of your child’s
changed behaviors and appearance you
can. If you feel the doctor is not listening
to you, write your concerns down and
hand it to the doctor. Keep a dated copy
for yourself. You may discover written
words get more response than spoken
words.
The same is true for seizures. The
physician needs to know in complete
and accurate detail how many seizures
your child has had and what type of
seizures they were. Many children have
more than one type of seizure, and it
is important to know the time, date,
number, and circumstances of each
of them. Sometimes small changes in
seizure patterns can give big clues to
more effective treatment. If you go into
the physician saying your daughter has
“had about the same number as last
time,” you aren’t providing the doctor
with much help. Keep a seizure diary.
Write both seizures and side effects
down. Be sure to bring it with you when
you see the doctor! There are several
pre-designed seizure diaries out there.
You don’t have to buy one, you can
create your own. The important part is
“do it.”

For 22 years, Robert J Mittan, PhD, has
been helping people with epilepsy and
their families. A clinical psychologist, he is
recognized as one of the foremost epilepsy
educators in the world. His work helping
others has earned many awards and his
research on epilepsy has resulted in new
and important discoveries.
The S.E.E. program is designed to give
people with epilepsy, parents of children
with epilepsy and family members the
information and skills needed to get the
best chance of becoming seizure free –
without letting treatment become part of the
problem.
Dr Mittan has presented this program to
over 30,000 people with epilepsy and their
families in Australia, Canada, New Zealand
and the USA.

Beating bad seizures
part 1: diagnosis
Requests to the editor for more articles by Bob Mittan,
confirms that his frank approach to understanding
epilepsy clearly resonates with many readers. In
response, The Epilepsy Report is pleased to present a
further 3-part series called ‘Beating Bad Seizures’ which
will look at diagnosis, treatment and what to do when
faced with difficult to control seizures.
What is epilepsy?
What is this thing we are dealing with
called a seizure disorder or epilepsy?
Epilepsy is the condition where a person
has recurrent, unprovoked seizures.
Recurrent means more than one.
Unprovoked means that the seizures
occur at a time when the body, and
especially the brain are not clearly sick
– there is no infection, stroke, or injury
occurring moments before the seizure.
The term seizure disorder is just another
name for epilepsy.
What causes a seizure? Most people
know seizures are due to an electrical
disturbance in the brain. A lot of people
have heard that a seizure is a “short
circuit” or an “electrical storm” in the
brain. I hate those explanations because
they are wrong and they scare people.
If you have ever seen a real short circuit
in an appliance or wall plug, it is a
frightening and destructive thing. POW!
and a shower of sparks. The same with
the example of lightning in a storm.
Parents who hear those explanations
are afraid seizures might be just as
destructive to their child’s brain cells,
with each seizure causing further brain
damage.
Our brains do operate using electricity,
but in very, very tiny amounts. Not
only that, these small electrical charges
stay inside each brain cell. The charges
are much too small to jump from one
brain cell to the next. Brain cells “talk”
with each other with chemicals, called
neurotransmitters, not with electricity.
So what is a seizure in the brain? A
seizure is like the “wave” you see in the
stadium at a football game. Normally
everyone in the crowd is doing their
own thing – talking, eating a hotdog, or
questioning the referee’s eyesight. Then
along comes a cheerleader who wants
the crowd to do the wave. Suddenly,
each person stops what he or she was
doing. Whole groups suddenly stand up
together and sit down again. The wave
spreads from one group of people to the
next until sometimes it goes around the
entire stadium. That is what a seizure is.
Normally brain cells are all doing their
individual thing. Then something comes
along that causes them to stop doing
their individual thing and instead join
with others to do the “wave.” Depending
upon where this “wave” starts, how far
it spreads, and how quickly the brain
cells “stand up and sit down,” you get
different kinds of seizures. The brain’s
electrical and chemical systems are
required for the “wave” to occur.
Diagnosis
Differences in seizure types are very
important. The medications used to
treat seizures often differ for different
kinds of seizures. If the seizures are
not correctly diagnosed, the wrong
medication could be chosen. So, the
starting point for effective treatment is
an accurate diagnosis. However, there
are several real challenges in coming
up with an accurate diagnosis. The
biggest one is what I call the First
Cosmic Law of Epilepsy. This law is
“Thou shalt never have thy seizure in
the doctor’s office where he or she can
see it!” Most children are very good
at obeying this law (they should do so
well with some other rules, right?) As
a result, the doctor must depend on a
description of the seizure from family
members who are inevitably frightened
at the time – and who have no training
in seizure observation! Often the doctor
can guess correctly, but this is not a
formula for diagnostic accuracy. This
is not the parents’ fault or the doctor’s
fault. We find on average that about 40
percent of parents who go through the
seizure observation training part of the
S.E.E. program discover that their child
has a different kind of epilepsy than they
thought.
Seizure Observation
What should you look for when
observing seizures? There are three
important observations to make: What
happened right as the seizure was
beginning, what happened during the
seizure, and finally, what happened after
the seizure was over.
There are two main families of
seizures. One of those families is
generalized seizures. The electrical /
chemical disturbance begins throughout
the brain all at once. There are several
different kinds of generalized seizures.
(See Table 1, Common Seizure Types.)
Because the whole brain participates in
the “wave” from the start, there is never
a warning that the seizure is about to
occur. It just suddenly happens. The
second family of seizures is partial
seizures. These seizures are called
“partial” because they start in a specific
part of the brain, not in the whole brain.
Unlike generalized seizures, partial
seizures can have a warning before they
occur. Sometimes this warning is called
an aura. Auras are actually a kind of
seizure (called simple partial seizures.)
What happens at the very beginning
of a seizure is often the most important
thing to observe. Carefully watching
the beginning of a seizure can give
important clues as to whether the seizure
is a partial seizure or a generalized
seizure. This is important because the
medications used to treat generalized
seizures tend to be different from the
ones used to treat partial seizures. If
the diagnosis is wrong, it is easy to
choose the wrong medication. In true
generalized seizures, there is never a
warning before a seizure occurs. Partial
seizures, however, may have a warning
rarely, often, or all of the time. Another
clue that a seizure is a partial seizure
is it starts in a specific part of the body
or begins with an unusual movement,
sensation, smell, emotion, or thought at
the start of the seizure. The spot in the
brain where the partial seizure starts is
called the seizure focus. Since different
parts of our brain do different things,
what happens at the beginning of the
seizure depends upon where the seizure
focus is located in the brain. This
means the first movement or sensations
that occur at the beginning of a partial
seizure are important clues as to where
in the brain the seizure focus is located
(See Figure 1, Seizure Focus and the
Brain.)
Often the second most important part
of the seizure to observe is what happens
after the seizure. After certain types of
seizures are over, the child is confused.
It may take minutes and sometimes
hours for the child to become completely
himself or herself. This is called post-
ictal confusion. “ Post” means “after,”
“ictal” is the medical term for a seizure
or event, and “confusion” refers to the
fact that the child may temporarily not
know where he or she is or what was
happening right after the seizure. Post-
ictal confusion is caused by a temporary
memory disturbance. Even when the
child has returned to full consciousness,
the memory disturbance can last for
hours after. This can make things like
learning in school or test taking difficult,
