THE EPILEPSY REPORT OCTOBER 2008
epilepsy had depression, 19% had suicidal thoughts, 37%
of patients were under- diagnosed and 17% of these patients
were not treated for depression. Wiegartz and his associates
(1999) in a study on comorbid psychiatric disorder in chronic
epilepsy reported that 43% with a current major depressive
disorder, 68% with a minor depressive disorder and 38% with
a history of a life-time episodes of major depression were not
treated. Ettinger et al (1998) reported that 26% of children
with depression and epilepsy were not treated for depression.
Although a substantial number of adolescents with epilepsy
exhibit depression & anxiety, many are not diagnosed or
treated. One of the reasons for under-diagnosis and under-
treatment might be that the manifestation of depressive
symptoms is atypical in patients with epilepsy.
The treatment for depression in epilepsy has been the usual
antidepressant drugs that are prescribed for depression in
patients without epilepsy. When prescribing antidepressants,
it is important to rule out whether the depressive episode
followed the discontinuation of an antiepileptic drug with
mood stabilising properties or that the depressive episode
followed the introduction or dose increment of an antiepileptic
drug with known negative psychotropic properties (Kanner,
2003). While some clinicians are concerned about worsening
the seizure frequency of patients who are treated with
antidepressants, the risk of psychiatric drugs causing seizures
is small. Tatum et al (2001) estimated that only 1 out of 100
patients had worsened seizures after treating for depression
with antidepressants. Although antidepressants are the
major treatment for depression, as many as 30% to 35% of
patients with major depression do not respond to treatments
(Aldessarini, 1989). A recent meta-analysis by Kirsch et al
(2008) found that antidepressant medications have reported
only modest benefits over placebo treatment, and when
unpublished trial data are included, the benefit falls below
accepted criteria for clinical significance
Among the non-pharmacological treatments, a wide
range of interventions such as psychotherapy, cognitive
behaviour therapy, relaxation therapy, exercise therapy and
counselling are used for treatment of depression in epilepsy.
Research indicates that a combination of antidepressants and
psychological treatments is far more effective than treatments
in isolation and has the potential for more long-term results.
As a group, patients with epilepsy tend to lack physical
fitness and live sedentary lives compared with the population
without epilepsy (Dubow & Kelly, 2003). The potential benefit
of physical exercise as an alternative treatment for depression
has received considerable attention in recent years. A growing
body of literature shows that depressive symptoms are
reduced with exercise (Singh et al, 2001). In a recent meta-
analysis, it was concluded that exercise was more effective
compared to no treatment and as equally effective as cognitive
behaviour therapy for depression (Lawlor & Hopker, 2001).
Craft and Landers (1998) in a systematic review on exercise
and depression found an overall mean effect size of .72. This
seems to be a substantial effect that proves the effectiveness
of exercise for patients with depression. Some studies have
shown that patients with epilepsy too would receive similar
benefits from physical activity. For example, Roth et al’s
(1994) study found that active subjects had significantly lower
levels of depression than inactive subjects, as well as better
psychosocial adjustment. Similarly, authors like Erikson et
al (1994) and Nakken et al (1990) have demonstrated that
an exercise intervention improved mental health, quality of
life and psychosocial functioning in patients with epilepsy.
Incorporating exercise programs for depression into a regular
lifestyle have also shown to be cost effective (Sevick et al,
2000).
Conclusion
Diagnosis and adequate management of depression is vitally
important for a number of reasons in patients with epilepsy.
It is well known that there is a strong correlation between
major depression and suicides. Suicidal behaviour is a specific
threat in patients with epilepsy as revealed by the suicide
rate of persons with epilepsy being more than five times that
of the general population. Patients with antidepressants and
antiepileptic drugs need to be followed carefully and closely
for side effects, particularly for suicidal ideation. Depression
may severely impair daily functioning of people with epilepsy.
Sleep deprivation can lead to, increased seizure frequency
as can non-compliance with medication. Most crucially,
depressed epilepsy patients may abuse their medication, both
antidepressants and anti epilepsy drugs (AEDs) which may
lead to fatal consequences. Quality of life can be poor in many
patients with epilepsy, however for those patients with epilepsy
whose depression remains untreated their quality of life will
be even more compromised.

The Epilepsy Foundation of Victoria (EFV) invites you to become an
occasional participant in the Epilepsy Foundation’s ongoing research
programme into the social effects of living with epilepsy and caring for those
with epilepsy. We need people to tell us about their experiences and views of
living with epilepsy.
What is EFV Research Participant Register (RPR)?
The Epilepsy Foundation of Victoria’s Research Participant Register is an
ongoing initiative created in 2006 to establish a unique research source
from which we can learn much valuable information about epilepsy that can
be used to improve the lives of people affected by this condition. This is the
only register of its kind in Australia and we have not so far learned of another
anywhere else in the world.
Why is it important to join in this register?
The World Health Organisation has stated that: the social consequences of
epilepsy are often more difficult to overcome than the seizures themselves.
They are talking about issues like finding and keeping a job, transport and
driving and the attitudes of other people towards epilepsy. Yet in Australia,
there is hardly any reliable research into these social consequences. If the
Epilepsy Foundation of Victoria gathers detailed factual evidence of this kind,
we will be even more successful in lobbying governments for a better deal and
a fairer go for all those living with epilepsy.
Who is eligible to join in RPR?
Following individuals are eligible to join the register.
Individuals who have epilepsy/seizure disorder
o
Carers who look after someone with epilepsy/seizure disorder
o
Are there risks to me as a research register participant?
This is not a medical or clinical research register. From time to time, we might
contact you and ask if you would be prepared to answer some questions
over the phone or fill in a mailed questionnaire. Sometimes there will be small
group meetings of participants at the Foundation’s office in Camberwell or a
regional centre to which you might be invited.
Does putting my name in the RPR obligate me to
participate in future research projects?
Putting your name does not obligate you in any way. You may be too busy
or just not feel like participating at that time – that’s fine! But if you do, any
information you provide will be confidential, anonymous, safeguarded and
only used for specified research purposes.
How would I benefit by joining the register?
There may be opportunities to talk with people living with epilepsy and those
who work with them. Most importantly, this is an opportunity to be part of a
longitudinal study of living with epilepsy – the first of its kind.

Megan O’Donoghue
passed away suddenly in
February 2007.
Megan’s friends and
family were left trying to
fathom the loss. A gifted
and creative amateur cook,
passionate about food
and wine, energetic social
organiser – Megan was a
girl who ‘ate’ life.
Inspired by Megan’s
culinary passions, the
concept of a ‘Megan cookbook’ – a way for her friends and family to
honour her memory – was born.
Now,
Megan Meals Memories written and edited by Andrea Neilson
is a reality and contains over 60 of Megan’s recipes – food she loved and
shared with friends and family. Food you will cook over and over again. All
the recipes, along with their accompanying stories, were contributed by
Megan’s friends and family, or leapt from the stained pages of her own
cookbook collection, demanding to be included.
“Andrea has brought all of the material together in a way which lets
Megan herself shine through, in the voices of the many contributors (and
sometimes in her own words), and which also movingly expresses Andrea’s
own love for a very dear friend.” – Jessica Ramsden (friend).
