The child's brain activity may be tested. This can be done with an EEG.
Treatment TOP
Some seizures will not need to be treated. Most children will outgrow seizures caused by fever by about 5 years of age.
Other seizures may stop once the underlying cause is treated. The child may need to stay at a hospital until seizures are controlled. Treatments to help control seizures may include:
Medications
Anti-seizure medicine can reduce the number of seizures or stop them completely. It may be given by IV for severe or frequent seizures. Pills can be given for seizures that are more sporadic.
Other Treatment
Some seizures may not respond well to medicine. Other possible treatments include:
- Ketogenic diet—a strict diet that is low in carbohydrates and high in fat. It may help stop seizures in some people. It is less effective for a type of seizure called focal seizures.
- Vagal stimulation—a device is implanted just under the skin. It will send signals to the vagus nerve. It may interrupt seizure signals.
- Surgery—to remove the area of brain causing the seizure.
