(Disorder, Seizure—Child; Epilepsy—Child)
is abnormal electrical activity in the brain. When 2 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 brain
- Partial 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,
tumor, or bleeding into the brain
Factors that may increase your child's chance of seizure disorder include:
or low birth weight
- Damage to brain during birth
- Abnormal brain structure
- Traumatic brain injury
- Brain infection
- Brain tumor
- History of febrile seizures
- Seizure within the first month after birth
- Family history of seizure disorder
Cysticercosis—an infection caused by a pork
Symptoms can vary depending on the type of seizure disorder. These may 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 sensations
- Staring, eye blinking, or eye rolling
- Loss of consciousness
- Repeated jerking of a single limb
- Uncontrollable jerking of muscles
- Hand rubbing, lip smacking, or picking at clothing
- Loss of bladder or bowel control
- Drowsiness or confusion after a seizure
You will be asked about your child’s symptoms and medical history. A physical exam will be done.
Tests may include:
- Blood tests
Lumbar puncture—to evaluate the cerebrospinal fluid that protects the brain and spinal cord
Imaging tests evaluate the brain and surrounding structures. These may include:
Your brain may be tested. This can be done with:
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 the child has.
Anti-epileptic 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, the child may need surgery. Surgery involves the removal of the area of the brain that starts the seizure. Surgery is only an option if the child has localized areas of the brain involved.
Vagus Nerve Stimulation (VNS)
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. Since children need proper nutrients, a dietitian will need to be involved.
Other Lifestyle Changes
A record of seizures may need to be kept. This may help identify and make plans to avoid seizure triggers. These triggers can vary from child to child but some examples include:
- Sleep deprivation
- Hormonal changes common during the menstrual cycle
- Flashing lights, such as strobe lights
- Use of certain medications or drugs
- Missing doses of anti-seizure medications
Help the child decrease the chance of a seizure by:
- Avoiding triggers
- Making sure anti-seizure medication is taken as prescribed
- Having the child get enough sleep
- Finding ways to help the child avoid hyperventilating, such as by doing deep breathing exercises and meditation
Other things to consider:
- Encourage wearing a medical alert bracelet. This will help people around the child understand what is happening if there is a seizure.
If a child’s condition is severe, take these steps to prevent serious injuries:
- Do not allow the child to swim or bathe alone.
- Do not have the child climb or play in areas where a serious fall could happen.
- Talk to the doctor to find out which activities are safe for the 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.
