Some seizures will not need to be treated. For example, children will outgrow seizures caused by fever by about 5 years of age. Others will be treated based on what is causing them. Underlying problems causing seizures will need to be treated.
Anti-seizure medicine may be given. The one that is used will depend on the type of seizure the child has.
Surgery may be needed in children with severe seizures who are not helped by medicine. Nerve fibers may be separated or a section of the brain that starts the seizure may be removed. It is only an option for children who have specific parts of the brain involved. It is not done often.
There are no known ways to prevent seizures.
