Summary
This is a study to see if vitamin E helps children with epilepsy have fewer seizures. About
20-30% of children with epilepsy do not have adequate seizure control with established
antiepileptic drugs (AEDs). Other options for patients with uncontrolled epilepsy are newer
antiepileptic medications, ketogenic diet and surgery. However, a small percentage of
patients are candidates for these options. Therefore, additional treatments are needed to
improve seizure control in patients with uncontrolled epilepsy. Animal studies have shown an
association between vitamin E supplementation and seizure reduction. A study in children also
showed that vitamin E helped reduce seizures. However, a similar study in adults did not show
a reduction in seizures with vitamin E supplementation. Therefore, this research study is
being done to help define vitamin E's usefulness and safety as a treatment for epilepsy.
Fifty patients will be recruited from the Children's Epilepsy Program at The Children's
Hospital in Denver, Colorado. Qualifying patients will have a confirmed diagnosis of epilepsy
that is currently uncontrolled with standard AEDs. The study period is 6 months and includes
the following: Baseline period (1 month), Arm I (2 months), Wash-out period (1 month), and
Arm II (2 months). Patients must have been on the same AEDs for 2 months before enrollment.
All medications and complementary therapies must remain constant throughout the study. If at
any point the physician feels it is not best for the patient to continue the study they will
be discontinued. Before the study starts, study participants will be asked about seizure
activity, what they eat and about any complementary and/or alternative medicine they may use.
The study is two phases. Study participants will be given either vitamin E or placebo (fake
pill/liquid) in each phase of the study. They will receive both vitamin E and placebo during
the study. Which phase they receive vitamin E and placebo will be decided by chance (similar
to rolling dice). Study participants will take liquid vitamin E or placebo two times per day.
The study participants and study doctors will not know who is taking vitamin E and who is
taking placebo. Study participants will come to the hospital for 3 outpatient and 2 inpatient
visits. Health-related quality of life questionnaires will be filled out and blood will be
drawn at three of the visits. Seizure diaries will be maintained throughout the study.
