What are antiepileptic drugs?
Antiepileptic drugs (AEDs)
Anticonvulsant medications
Antiseizure medications
4. 5/20/15
4
Antiseizure medications
Drugs that decrease the frequency and/or
severity of seizures in people with epilepsy
Treat the symptom of seizures, not the
underlying epileptic condition
They don’t change the course of the disease
Antiepileptic drugs
Drugs that prevent the development of recurrent
seizures in people at risk
Drugs that reduce seizure frequency and severity
outlasting the treatment period
Example: after head trauma, stroke, brain tumors, etc.
Animal studies suggest that Levetiracetam and
Ethosuximide are potential antiepileptic drugs BUT
there are no studies in humans to support this
5. 5/20/15

Use of antiseizure medications

Uncommon - rare
Potentially serious or life threatening
Chronic: reversibility and seriousness vary
11. 5/20/15

Acute - Dose-Related Adverse
Effects of AEDs
Neurologic/psychiatric: most common
• Sedation, fatigue
- All AEDs, except unusual with LTG and FBM
- More pronounced with traditional AED
• Unsteadiness, poor coordination, dizziness
- Mainly traditional AEDs
- May be sign of toxicity with many AEDs
• Tremor – valproate
• Depression ????
Acute, Dose-Related Adverse
Effects of AEDs (cont.)
• Parenthesis (topiramate, zonisamide)
• Diplopia, blurred vision, visual distortion
(carbamazepine, lamotrigine)
• Mental/motor slowing or impairment (topiramate at
higher doses)
• Mood or behavioral changes (levetiracetam)
• Changes in libido or sexual function
(carbamazepine, phenytoin, phenobarbital)
12. 5/20/15

Acute, Dose-Related Adverse
Effects of AEDs (cont.)
Gastrointestinal (nausea, heartburn)
Mild to moderate laboratory changes
• Hyponatremia: carbamazepine, oxcarbazepine

Idiosyncratic Adverse
Effects of AEDs
Toxic Epidermal necrolysis
Stevens-Johnson syndrome
More common in lamotrigine, patients receiving valproate and/
or aggressively titrated.
Signs of potential Stevens-Johnson syndrome
Hepatic damage
Early symptoms: abdominal pain, vomiting, jaundice
Laboratory monitoring probably not helpful in early detection
Patient education
Fever and mucus membrane involvement
HLA-B 1502 and AED induced
rash
Racial groups: Han Chinese and other South
East Asian groups
Drugs: Carbamazepine, Oxcarbazepine,
Phenytoin, Fosphenytoin
US FDA recommendations:
Genotypic all Asian descend patients before
therapy
(Ferrell and McLeod. Pharmacogenomics 2008)
14. 5/20/15
14
AED Hypersensitivity
Syndrome
Characterized by rash, systemic involvement
hydrolase
Cross-reactivity
Phenytoin
Carbamazepine
Phenobarbital
Oxcarbazepine
Relative cross reactivity - lamotrigine
Idiosyncratic Adverse
Effects of AEDs
Hematologic damage
Marrow aplasia, agranulocytosis, aplastic anemia
Early symptoms: abnormal bleeding, acute onset of fever,
symptoms of anemia
Laboratory monitoring probably not helpful in early
detection
Felbamate aplastic anemia approx. 1:5,000 treated
patients
Patient education
16. 5/20/15

Drug interactions
Pharmacokinetic Interactions
Be aware that drug interactions may occur when
there is the:
Addition of a new medication when an inducer/
inhibitor is present.
Addition of inducer/inhibitor to an existing
medication regimen.
Removal of an inducer/inhibitor from chronic
medication regimen.
17. 5/20/15
17
Hepatic Drug Metabolizing Enzymes
and Specific AED Interactions
Phenytoin: CYP2C9/CYP2C19
Inhibitors: valproate, ticlopidine, fluoxetine, topiramate,
fluconazole
Carbamazepine: CYP3A4/CYP2C8/CYP1A2
Inhibitors: ketoconazole, fluconazole, erythromycin,
diltiazem
Lamotrigine: UGT 1A4
Inhibitor: valproate
Important note about oral contraceptives (OCPs):
OCP efficacy is decreased by inducers,
including: phenytoin, phenobarbital, primidone, carbamazepine;
and higher doses of topiramate and oxcarbazepine
OCPs and pregnancy significantly decrease serum levels of
lamotrigine.
Potent inducers
Carbamazepine, Phenobarbital, Phenytoin
Effect of induction is seen within the first 3 weeks of treatment
Caution when prescribing Bupropion, Quetiapine, etc
Definitively have a significant effect over the metabolism of
Sex hormones
Vitamin D
Thyroid hormones
Lipid metabolism
Folic acid
18. 5/20/15
18
Mild inducers
Clobazam, eslicarbazepine, felbamate,
lamotrigine, oxcarbazepine, rufinamide,
topiramate, vigabatrin, and vaproic acid
Can be inducers at higher doses
Sometime have combined inhibitor effects
It can take months before the maximum effect
is seen
Effect on systemic metabolism is present at a
lesser degree
AEDs and Drug Interactions
Although many AEDs can cause pharmacokinetic
interactions, several agents appear to be less
problematic.
AEDs that do not appear to be either inducers or
inhibitors of the CYP system include:
Gabapentin
Lamotrigine (low dose)
Pregabalin
Tiagabine
Levetiracetam
Zonisamide

Take home points
Antiseizure medications are prescribed taking
into account a number of factors
Keep in mind drug drug interaction when
prescribing antiseizure medications
A multidisciplinary team, that includes a
Psychiatrist, is a very important part of the
care for patients with epilepsy

MRI Findings
• Anxiety is a common psychiatric
comorbidity in children with recent-onset
epilepsy.
• Potential neuroanatomical substrate
consisting of volumetric enlargement of
the amygdala. Daley et al. (2008) reported
a similar finding.
• Thinner cortex in orbital and other regions
of prefrontal cortex.
MRI findings
• There are abnormalities in brain structures
that are involved in the networks found in
individuals with anxiety disorders in the
general population.
• These anatomic findings:
– are evident early in the course of epilepsy.
– are not related to chronicity of seizures.
– are linked to a family history of anxiety and
depressive disorders.
37. 5/20/15
37
2 Year Follow-up
• Children with epilepsy returned for follow-
up 2 years after their baseline evaluation.
• Healthy controls also returned.
• The KSADS was repeated with child and
parent separately.

Batzell
&
Dodrill
(1986)
• At
Baseline:
– 42%
children
with
epilepsy
and
anxiety
had
suicidal
thoughts.
– 45%
children
with
epilepsy
and
no
anxiety.
• At
Follow-‐up:
– 21%
children
with
epilepsy
and
anxiety
had
suicidal
thoughts.
– 34%
children
with
epilepsy
and
no
anxiety.
• Suicidal
thoughts
are
common
in
children
with
epilepsy
and
anxiety.
• Suicidal
thoughts
are
also
quite
common
in
children
with
epilepsy
without
anxiety.

Poorer HRQOL is significantly associated with
increased symptoms of anxiety.

Treatment Recommendations
• No
randomized
controlled
trials
for
the
treatment
of
anxiety
disorders
in
children
or
adults
with
epilepsy,
including
pharmacological
and
nonpharmacological
intervenVons.
• Very

Pharmacological Treatment
• There are no randomized controlled trials
of the use of SSRIs in the treatment of
anxiety disorders in adults or children with
epilepsy.
• There is evidence to suggest that seizure
frequency is not adversely impacted by the
introduction of SSRIs.
• Anxiety
is
common
in
adults
and
children
with
epilepsy.
• There
are
potenTal
neuroanatomical
substrates
idenTfied
in
children
with
epilepsy
similar
to
those
reported
in
the
general
populaTon.
• Anxiety
has
a
negaTve
impact
on
overall
QOL.
• Anxiety
is
frequently
under
recognized
and
under
treated.
43. 5/20/15
43
• Only
1/3
of
children
with
epilepsy
and
mental
health
problems
receive
treatment
(OM
et
al.,
2001).
• Parents
report
that
emoTonal
and
behavioral
problems
are
very
concerning
to
them
(Wu
et
al.,
2008).
• Neurologists
&
pediatricians
who
treat
children
with
epilepsy
feel
there
is
a
resistance
on
the
part
of
mental
health
providers
to
treat
children
with
epilepsy
(Smith
et
al.,
2007).

Psychogenic Non Epileptic Seizures are

As
a
psychiatrist,
you
can
establish
the
diagnosis
of
PNES
after
carefully
reviewing
the
exam
and
tests
that
confirm
incompatibility
between
the
symptom
and
the
preserved
physiological
functioning.
Always
confer
with
a
neurologist.
Early
screening
for
risk
factors
can
help
you
formulate
an
explanatory
model
for
the
patient.
There
is
growing
evidence
of
effective
treatments
for
PNES,
mostly
based
on
psychotherapeutic
interventions.

a

of
outcome
patterns
in

patients.
Identifying
subgroups
of
patients
with
different
outcomes
may
help
customize

protocols
for
subpopulations
and
improve
overall
functional
outcomes.

Make sure that you listen,
make sure that you care,
make sure
you are watching —
something’s always there.
