Absence seizures are brief, unexpected periods of losing awareness. They happen more often in children than adults.
During an absence seizure, a person might look blankly ahead for a few seconds, seemingly lost in thought. They usually snap back to alertness quickly. These seizures typically don't cause physical harm. However, there's a risk of harm if the person is doing something active, like driving a car or riding a bicycle, because they might lose control during the seizure.
Doctors often treat absence seizures with medication. Sometimes, children with absence seizures may also develop other types of seizures, like generalized tonic-clonic seizures (where the body stiffens and shakes) or myoclonic seizures (sudden muscle jerks). Many children eventually outgrow absence seizures as they get older, often by their teenage years.
Absence seizures are a type of brief seizure that can look like a person is just staring blankly, or having a short moment of inattention. These seizures usually last between 10 and 30 seconds. Importantly, there's no confusion, headache, or sleepiness afterward.
During an absence seizure, a person might:
Often, the person has no memory of the seizure afterward. However, if the seizure lasts longer than about 10 seconds, they might be aware that some time has passed. Some people have many of these seizures every day. This can impact their ability to focus on schoolwork or other activities.
Sometimes, absence seizures go unnoticed for a while, especially in children. This is because the seizures are so short. One of the first signs parents or teachers might notice is a decrease in a child's learning ability. Teachers might describe the child as having trouble paying attention, or as often daydreaming.

Absence seizures are often linked to genetics.
Normally, your brain's nerve cells, called neurons, send electrical signals to each other. These signals travel across tiny gaps called synapses. Think of it like a network of tiny wires and connections.
In people with absence seizures, something disrupts this normal electrical activity. Instead of the usual, smooth flow of signals, there are repeated bursts of activity, happening about every three seconds. This pattern of repeated signals is what defines an absence seizure.
These seizures might also be related to problems with the brain's chemical messengers, called neurotransmitters. These neurotransmitters help neurons communicate effectively. If the balance of these chemicals is off, it can affect how the neurons talk to each other, potentially leading to seizures.
Absence seizures, a type of seizure that can affect children, often share some common traits.
Age: Most children who have absence seizures are between the ages of 4 and 14. This means that this type of seizure is more frequently seen in this age group.
Gender: Girls are slightly more likely to experience absence seizures than boys.
Family history: About one in four children with absence seizures have a family member who has had seizures. This suggests a possible genetic link, but other factors likely play a role as well. Having a family member with seizures doesn't guarantee a child will have them, but it does increase the chance.
Many children with absence seizures, a type of seizure that causes brief lapses in awareness, will eventually outgrow them. However, some children need to continue taking medication to control these seizures for the rest of their lives. In other cases, absence seizures can progress into more serious types of seizures, like full-body convulsions (also called generalized tonic-clonic seizures).
Beyond the seizures themselves, there are other potential problems that can arise:
Learning difficulties: Children may experience challenges with schoolwork and academic performance. This could involve trouble with reading, writing, math, or other subjects.
Behavioral issues: Changes in behavior, such as difficulty with focus, impulsivity, or mood swings, are possible. These can make daily life more challenging for both the child and their family.
Social isolation: Seizures and associated problems can sometimes lead to social difficulties. Children might feel excluded from activities or have trouble making and maintaining friendships.
Potential for injury: During a seizure, a child could fall or injure themselves, requiring medical attention.
In summary, while many children recover from absence seizures, some face ongoing challenges. These can include the need for lifelong medication, the progression of seizures, and related issues like learning problems, behavioral challenges, social isolation, and the risk of injury.
An EEG, or electroencephalogram, is a test that measures the electrical activity in your child's brain. Small, metal sensors called electrodes are placed on their scalp with a special paste or cap. The electrodes pick up the brain's electrical signals and send them to a machine that records them. Doctors use these recordings to look for changes that might indicate a problem, especially if your child has seizures or epilepsy.
If your child has seizures, their doctor will want a lot of information about them. They'll likely ask detailed questions about the seizures, like when they happen, how long they last, and what your child does during them. The doctor will also do a physical exam to check for other clues.
To help find out what might be causing the seizures, the doctor might order other tests, including brain scans. Brain scans, like MRI scans, create detailed pictures of the brain. These pictures can help rule out other possible problems, such as strokes or brain tumors. Because these scans require your child to stay very still for a while, your doctor may recommend medicine to help them relax and stay still, called sedation.
The EEG itself is a painless procedure. The electrodes don't hurt, and the machine just records the brain's electrical activity. During the EEG, it's important to be aware that sometimes things like fast breathing (hyperventilation) can sometimes trigger a type of seizure called an absence seizure. The EEG will show a different pattern of brain activity during a seizure compared to a typical brain activity pattern.
Doctors often start children with the lowest possible dose of anti-seizure medicine. They gradually increase the dose until the seizures are controlled. If a child is seizure-free for two years, their doctor might help them slowly reduce the medicine.
Different medicines work better for different types of seizures. Here are some common ones used for absence seizures:
Ethosuximide (Zarontin): This is a common first choice for absence seizures. It often helps control seizures effectively. Possible side effects include feeling sick to your stomach (nausea), vomiting, sleepiness, trouble sleeping, and sometimes, hyperactivity.
Valproic acid: This medicine can help children who have both absence seizures and other types of seizures, like tonic-clonic seizures (sometimes called grand mal seizures). Possible side effects include nausea, problems concentrating, increased appetite, and weight gain. In rare cases, it can cause inflammation of the pancreas or even liver problems. Important Note: If a girl needs this medicine into adulthood, she and her doctor should discuss the potential risks, especially because valproic acid is linked to a higher risk of birth defects in babies. Doctors generally don't recommend using it during pregnancy or while trying to get pregnant.
Lamotrigine (Lamictal): Some studies suggest this medicine might not be as effective as ethosuximide or valproic acid for some children, but it often has fewer side effects. Possible side effects include skin rashes and nausea.
It's crucial that parents and children work closely with their healthcare providers to find the best treatment plan. This plan will consider the type of seizures, the child's overall health, and any potential side effects. The doctor will carefully monitor the child's response to the medicine and adjust the dosage as needed.
