is abnormal electrical activity in the brain. When two or more seizures occur, it is considered a seizure disorder, also known as epilepsy. While there are many different types of seizures, the main categories are:
Generalized seizure—activity occurs throughout the brainPartial seizure, also called a focal seizure—begins within certain areas of the brain
Abnormal and excessive electrical activity in the brain.

Seizure disorder is caused by abnormal brain function. It is often difficult to identify the exact cause, but some factors that may play a role include: Genetic disorder
Brain abnormalities or damage such as infection,
, or bleeding into the brain
Factors that increase the risk of a seizure disorder include: Premature birth
or low birth weight
Damage to brain during birthAbnormal brain structureTraumatic brain injuryBrain infectionBrain tumorHistory of febrile seizuresSeizure within the first month after birthFamily history of seizure disorder
Cysticercosis—an infection caused by a pork
Symptoms can vary depending on the type of seizure disorder. Examples of symptoms include: Aura—a sensation at the start of a seizure such as perception of an odd smell or sound, spots appearing in front of the eyes, or stomach sensationsStaring, eye blinking, or eye rollingLoss of consciousnessRepeated jerking of a single limbUncontrollable jerking of musclesHand rubbing, lip smacking, or picking at clothingLoss of bladder or bowel controlDrowsiness or confusion after a seizure
The doctor will ask about your child’s symptoms and medical history. A physical exam will be done.
Your bodily fluids may be tested. This can be done with: Blood testsLumbar puncture
Images may be taken of your bodily structures. This can be done with: MRI scanCT scan
Your brain may be tested. This can be done with: Electroencephalogram
You will work with the doctor to choose a treatment plan that is right for your child. Treatments options include:
There are many different kinds of medications to treat seizure disorder. The exact medication will be based on the specific type of seizures and symptoms your child has.
Antiepileptic medications are a common option. In some cases, anti-epileptic medications may be used in combination.
If medication does not work or the side effects are too severe, your child may need surgery. Surgery involves the removal of the area of the brain that starts the seizure. Surgery is only an option if your child has localized areas of the brain involved.
With VNS, a device is implanted in the chest to give electrical stimulation to the vagus nerve. This nerve runs from the brain to beyond the stomach. Stimulation can prevent or decrease the frequency of seizures. Medication may still be needed.
A ketogenic diet is a strict
. It is high in fat and low in carbohydrates and proteins. It keeps the body’s chemical balance in a state of ketosis. Ketosis decreases the frequency of seizures. If you would like your child to start this diet, talk to the doctor. Since your child needs proper nutrients, you will need to work with a dietician.
Your doctor may ask you to keep note of what was happening when your child had a seizure. This may help identify and make plans to avoid seizure triggers. These triggers can vary from child to child but some examples include: Sleep deprivationStressHormonal changes common during the menstrual cycleFlashing lights, such as strobe lightsUse of certain medications or drugsMissing doses of anti-seizure medications
Help your child to decrease the chance of a seizure by: Avoiding triggers.Making sure anti-seizure medication is taken as prescribedHaving your child get enough sleepFinding ways to help your child avoid hyperventilating, such as by doing deep breathing exercises and meditation
Other things to consider: Encourage your child to wear a medical alert bracelet. This will help people around your child understand what is happening if there is a seizure.
If your child’s condition is severe, take these steps to prevent serious injuries:
Do not allow your child to swim or bathe alone.Do not have your child climb or play in areas where a serious fall could happen.Talk to the doctor to find out which activities are safe for your child. Certain sports may need to be avoided.
There are no known ways to prevent every type of seizure disorder. You can take steps to prevent your child from brain injuries or conditions that could lead to seizures: Get prenatal care.Be sure that your child always wears a helmet when doing certain activities such as bike riding, skateboarding, and playing contact sports.Have your child wear seat belts or sit in a car seat when riding in a car.Teach your child never to dive into water. To be safe, your child should always go into the water feet first.
