TREVOR RESNICK, MD: There are various kinds of generalized seizures that are characterized by generalized body stiffening or by just staring blankly ahead or by having staring followed by jerking, followed by stiffening.
There are seizures that are partial. Those seizures are unassociated with a change in consciousness. So for example, a child may be jerking the left arm and be able to say, "What's wrong with me? My left arm is jerking."
Partial complex seizures render the child to have a change in consciousness where they're not entirely with it.
ANNOUNCER: Since epilepsy can appear in different ways, it's often hard to identify. Physicians rely on a variety of information to pinpoint the problem.
TREVOR RESNICK, MD: The history that you get from the family or the patient really is your best clue. And the backbone diagnostic help for the diagnosis of a patient with seizures or epilepsy is an EEG, which is a brainwave test.
ANNOUNCER: Of course eliminating the seizures is on every parent's, and every child's, wish list. For years medication gave some relief but it came at a cost.
TREVOR RESNICK, MD: So you may get an effect on cognition. You may get dizziness. You may get double vision. There may be various other kinds of effects on brain function.
The older medications had a greater propensity to have those kinds of side effects, but not always.
ANNOUNCER: These kinds of side effects could be almost as bad as the seizures.
