A seizure is a sudden, abnormal wave of electrical activity in the brain. A child who has had two or more seizures may be diagnosed with epilepsy.
About one in 26 people who have a seizure will develop epilepsy. Epilepsy affects people of all ages, races and ethnic backgrounds. Some people with epilepsy outgrow the tendency to have seizures. Others do not.

There are many types of epilepsy in children. Some are more common than others. Rare epilepsy types can be difficult to recognize. Doctors play a critical role in diagnosing and treating all types of childhood epilepsy.
Localization-related epilepsy means that the seizure activity begins in one specific part of the brain. These are also called focal seizures.
The most common type of localization-related epilepsy is temporal lobe epilepsy. The brain has two temporal lobes. One temporal lobe is on each side of the brain, by each ear. They process emotions. They are important for short-term memory. When a child’s seizures start in a temporal lobe, it is called temporal lobe epilepsy.
The brain has three other lobes—the frontal, occipital and parietal lobes. Less commonly, seizures can start there.
If a child still has seizures after taking two seizure medications, the epilepsy is called “intractable.” Doctors sometimes call this condition “medication resistant” or “drug-resistant epilepsy.” Intractable epilepsy is still treatable. Some children can be seizure-free with expert care. The care team can offer more treatment options. These could include a specialized diet or a surgery evaluation.
An epilepsy syndrome has features that usually happen together. These features may include:
It is helpful when the medical team can classify a child’s epilepsy as being part of a syndrome. This can help direct what treatments will be most effective. It can also help provide a better view of the child’s overall epilepsy outlook.
Below are the most common epilepsy syndromes affecting children.
Most of the time, a child’s seizures won’t be part of a syndrome. In this situation, the child may be diagnosed with “idiopathic” epilepsy. Another word for idiopathic is “unknown.”
The main symptom of epilepsy is seizures that happen again and again. Epilepsy always involves seizures. But not all seizures are caused by epilepsy.
A seizure temporarily affects how a person acts, feels or appears. It may or may not have visible signs like jerking movements or stiffening of the arms and legs. You may also notice:
The child may pick at their clothes, lose muscle control suddenly or stare into space. Their breathing pattern may change but rarely stops entirely. When the seizure is over, the child may be extremely sleepy and need rest.
There is no single cause for seizures. In many cases, the cause is unknown. But some known causes (some of which can overlap) include:
Another cause for seizures relates to differences in how the brain is shaped or formed. Cortical dysplasia is one example of this. Cortical dysplasia happens when the top layer of the brain does not form properly. A related condition is hemimegalencephaly, in which one side of the brain is much larger than the other. It causes frequent seizures and usually involves intellectual disability.
Epilepsy is a complex condition. Some of its symptoms look like those of other diseases. Making an accurate diagnosis can be challenging. But it is an important step toward setting up an effective treatment plan.
It is important to know:
Seizures rarely happen when a child’s doctor is present. So, the medical team relies on parents and caregivers to share a detailed description from people who have seen the seizures. Cell phone videos of events are very helpful to show the doctor.
Medical tests also are important. These tests provide information about:
Medical tests to help with diagnosis of epilepsy include:
The goal of epilepsy treatment is to be free from seizures with minimal or zero side effects. Starting an anti-seizure medication is the first step. If a child’s seizures still happen after taking two carefully chosen seizure medications, the epilepsy is called “intractable.” Taking another medication will not help. The care team will talk to the family about other treatment options.
Anti-seizure medication is effective for many children. This medicine helps control seizures. The doctor will choose the medicine based on the child’s:
Finding the right drug(s) can take time. The doctor might need to adjust dosages. Or they might change medications.
Specialized diets can help some children achieve seizure control. These diets include the ketogenic diet and the modified Atkins diet. Both have high fat, low or zero carbohydrates and moderate protein. These diets may help children who have not been helped by seizure medicines. They may also help children who aren’t surgical candidates. Talk to your doctor before you start a specialized diet for epilepsy.
When medication and / or a specialized diet doesn't work, surgery may be needed. The goal of surgery is to dramatically reduce how severe and often seizures are happening. Sometimes, surgery may get rid of seizures. There are many kinds of surgeries for epilepsy. Some surgeries remove or destroy diseased tissue that is causing seizures. Others involve implanting devices that can send electrical signals to the brain to shorten or prevent seizures.
Many children with epilepsy outgrow their tendency to have seizures. Medication, diet or surgery can help many to be free of seizures.
However, children with epilepsy are at risk for:
Sometimes these difficulties are related to seizures. Sometimes there are medication side effects.
An experienced team of epilepsy specialists can help identify these concerns. They can also provide treatment so that the child can enjoy the best quality of life possible.
Most children with epilepsy who receive timely specialty care have healthy, normal lives and can enjoy school and sports.
