A seizure 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:
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:
Factors that may increase your child's chance of seizure disorder include:
Symptoms can vary depending on the type of seizure disorder. These may include:
You will be asked about your child’s symptoms and medical history. A physical exam will be done.
Tests may include:
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.
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 diet. 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.
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:
Help the child decrease the chance of a seizure by:
Other things to consider:
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:
