Epilepsy: Recognizing It, Managing It, and the Family's Role

Why Is It So Common?

Somewhere between about a third and a half of children with cerebral palsy have epilepsy (repeated, unprovoked seizures); this rate is clearly higher in children whose brain injury is more extensive — especially when it also involves the cortical and subcortical regions — and who have severe motor involvement (GMFCS IV–V). The reason is simple: the brain regions that control movement and the regions prone to producing seizures are often neighboring or overlapping areas, and the same injury process can affect both at once.

Epilepsy accompanying cerebral palsy does not mean your child's picture is "more severe"; it simply means there is one more area to manage. With the right diagnosis and treatment, seizures can be brought under control or their frequency clearly reduced in a large proportion of children who have both cerebral palsy and epilepsy.

This close relationship between epilepsy and cerebral palsy does not mean that one "creates" the other; both are different expressions of the same underlying brain injury. Understanding this distinction helps families put the worry "is epilepsy making the cerebral palsy worse?" into a more accurate frame.

Recognizing the Types of Seizures

When people hear the word "seizure," they usually picture stiffening and shaking of the whole body (a generalized tonic-clonic seizure); but seizures can appear in far more varied — and sometimes hard-to-notice — forms. In focal seizures, awareness may be kept, and there may be twitching, tingling, or a strange sensation in just one arm, one leg, or one side of the face; sometimes awareness becomes clouded and the child makes vague, purposeless movements (such as lip-smacking or fumbling with clothing). In absence (staring) seizures, the child stares blankly and stays still for a few seconds, then carries on from where they left off; these seizures are often mistaken for "daydreaming" or "inattention" and may go unnoticed for months. In myoclonic seizures, there are sudden, brief, lightning-like muscle jerks. In infants, the spasms known as infantile spasms (West syndrome) show up especially on waking, as brief episodes of the head and trunk bending forward and the arms flinging out, repeating in clusters — and they require urgent evaluation.

If you notice odd, repeated, brief changes in your child's behavior — such as blinking, staring off, twitching in a single limb, sudden falls, or unexplained expressions of fear or panic — recording them with your phone if possible and sharing them with your doctor makes a huge contribution to the diagnostic process. A video carries far more information than a spoken description ever could.

Some seizure types can be so brief and mild (very short myoclonic jerks, for example) that families may not notice them for a long time. If you notice any repeated, brief movement pattern in your child that you haven't seen before, I'd advise you not to dismiss it as unimportant, but to share it with your doctor.

What to Do During a Seizure? (First-Aid Steps for Families)

Staying calm during a seizure is important both for your child's safety and for accurate observation. Move the child away from hard or sharp objects, and put something soft (clothing, a pillow) under their head. If possible, turn the child onto their side to keep saliva or vomit from going into the airway. Do not put anything (a spoon, a finger, medicine) into their mouth during the seizure; this can injure their teeth and you, and it will not stop the seizure. Do not try to hold the child down or stop their movements. Note the time the seizure started, or record it with your phone if you can; this information is very valuable to your doctor.

After the seizure ends, the child is often sleepy, confused, or temporarily weak (Todd's paralysis); during this time, stay with them, reassure them, and let them recover on their own.

Some families feel great panic when they see the first seizure; this is a completely understandable reaction. Over time, with repeated experience, most parents learn to act more calmly and in a more organized way during a seizure. Be patient with yourself in this process; it's normal not to have carried out every step perfectly the first time.

When Should You Go to the Emergency Room? Status Epilepticus

If a seizure lasts longer than 5 minutes, or if the child has one seizure after another without fully regaining awareness in between, this is called status epilepticus, and it requires urgent medical care; you should call emergency services (112) immediately or go to the nearest emergency room. The risk of a prolonged seizure is higher in children with cerebral palsy than in the general population; for this reason, your doctor may prescribe a "rescue medication" that can be given at home (for example, buccal or intranasal midazolam) and can teach you when and how to give it. Having this kind of written emergency plan available at home, at school, and with everyone who cares for your child can be lifesaving.

Diagnosis: The Role of EEG and Imaging

The diagnosis of epilepsy rests first and foremost on the clinical picture as described by your child and by those who witnessed the event; electroencephalography (EEG) is a test that supports this clinical assessment by recording the electrical activity in the brain. In some situations — especially when the seizure type is not clear, or when seizures need to be told apart from non-seizure movements (such as dystonia or reflexes) — a video-EEG (an EEG recorded at the same time as video) may be needed; by capturing both the picture and the electrical activity at once, this is the most reliable diagnostic method.

I'd like to emphasize an important point here: not every abnormality seen on an EEG means epilepsy that must be treated. In some children, epileptiform (seizure-like) electrical activity can be found on the EEG without any clinically noticeable seizure; this is called "subclinical epileptiform activity." Whether or not this finding should be treated must be decided individually by your child's neurologist, taking into account the child's overall clinical picture, development, and how often this activity occurs; starting medication for every EEG abnormality is not the right approach.

During an EEG recording, electrodes are placed on your child's head; this is painless, but especially for young children, the feel of the electrodes or the texture of the gel can be uncomfortable. Explaining what will happen beforehand in age-appropriate language, doing a "rehearsal" on a doll, or distracting your child with something they enjoy (such as watching cartoons) can make the procedure easier. Video-EEG recordings can last hours, sometimes days; it helps to prepare ahead of time, knowing you may need to stay in the hospital during this process.

Principles of Treatment

The choice of anti-seizure medication is made according to the seizure type and, if present, the underlying epilepsy syndrome; the preferred medication groups are different for focal seizures, generalized tonic-clonic seizures, absence seizures, and myoclonic seizures — in fact, some medications can make certain seizure types worse. For this reason, the choice of medication must always be individualized, and it should never be changed based on internet research or another family's experience.

In choosing medication for children with cerebral palsy, alongside seizure control, the child's accompanying problems are also taken into account: effects on cognition and behavior, effects on bone health (which is already fragile due to reduced movement), effects on appetite and weight, effects on saliva production, and possible interactions with other medications (such as those used to treat spasticity) are all carefully weighed. All anti-seizure medications are increased slowly and gradually (titrated) and are never stopped suddenly; stopping abruptly can cause seizures to worsen and can even lead to status epilepticus.

In choosing medication, your child's school schedule can also be taken into account; for example, the time of day a clearly sedating medication is given can be planned so it doesn't affect school performance. Don't hesitate to talk to your doctor about these kinds of practical adjustments; fitting treatment into daily life matters just as much as how effective it is.

Drug-Resistant Epilepsy and Additional Treatment Options

In some children, seizures continue despite properly tried trials of two or more anti-seizure medications; this is called "drug-resistant epilepsy." Additional options that can be considered in this situation include the ketogenic diet (a special high-fat, low-carbohydrate eating program carried out under medical supervision), vagus nerve stimulation (regular stimulation of the vagus nerve using a device placed under the skin of the chest), and, in selected, well-defined cases with a one-sided brain lesion, epilepsy surgery. Whether the ketogenic diet is feasible in a child with cerebral palsy must be assessed separately, taking into account the child's nutritional status and swallowing ability.

Practical Advice for Families

Keeping a seizure diary — the date, time, duration, seizure type, possible trigger (such as fever, lack of sleep, or a missed dose), and the state after the seizure — greatly helps your doctor adjust treatment. Giving medications regularly, without skipping a single dose (medication adherence), is one of the most important factors in seizure control; clarify with your doctor ahead of time what to do if a dose is missed. Share a written emergency plan for what to do during a seizure with your school, your caregiver, and everyone who spends time with your child. Finally, a diagnosis of epilepsy does not prevent your child from playing, socializing, or (with safety measures in place) taking part in most everyday activities; being overly restrictive can harm your child's overall development more than epilepsy itself does.

Building Seizure Awareness at School and Out in the World

In every setting where a child with epilepsy takes part in daily life — school, sports club, summer camp, visits to relatives — it's important for your child's safety that the adults in that setting know basic seizure first aid. When you share this information, doing so calmly and practically, without creating an atmosphere of exaggerated anxiety, helps both your child and the people around them feel at ease.

Some families choose to keep their child's epilepsy diagnosis private; this can come from an understandable worry (fear of stigma). But for safety, having the adults who regularly spend time with your child know this information can be lifesaving in the event of a seizure. Whom you share this information with, and to what extent, is your decision; but I'd encourage you to strike this balance between safety and privacy consciously.

Watching for Medication Side Effects

When any anti-seizure medication is started, your doctor should explain the side effects specific to that medication that you should watch for (for example, drowsiness, change in appetite, change in behavior, rash, balance problems). Some of these side effects appear in the first days or weeks and ease over time, while others may be dose-related and can be managed by adjusting the dose. Watching your child closely in the first weeks after starting a new medication and noting the changes you notice helps your doctor adjust the dose or the medication if needed.

Some anti-seizure medications may need to be monitored with regular blood tests (such as liver function, blood counts, and drug levels); following the follow-up schedule your doctor recommends allows possible side effects to be caught early.

The Difference Between Febrile Seizures and Epilepsy

Some children with cerebral palsy can have seizures that occur only when their temperature rises (febrile convulsions); this is different from epilepsy, which involves repeated seizures without fever, and it usually carries a different management and outlook. However, in some children, febrile seizures can turn into epilepsy over time or can reveal an underlying tendency toward epilepsy; for this reason, it's important to share every febrile seizure event with your doctor and to have it assessed in detail if needed.

What you should do during a febrile seizure is largely the same as what you do during an afebrile (feverless) seizure: stay calm, put the child in a safe position, and watch the duration. Trying to bring the fever down quickly (aggressive methods such as sponging with cold water) is generally not recommended; instead, the fever reducers your doctor recommends should be used at the appropriate dose.

Practical Ways to Make Medication Easier to Keep Up With

To make it easier to keep up with daily medication, it can help to use weekly pill boxes, set up phone reminders, and tie medication times to daily routines (such as breakfast or bedtime). For school-age children, if a dose needs to be given at school, sharing clear written instructions with the school nurse or the staff member in charge makes sure the dose isn't skipped.

Some children resist taking medication because they don't like the taste; in this case you can ask your doctor about a different formulation (a syrup instead of a tablet, or vice versa) or about taste-masking methods. Instead of forcing the medication and upsetting the child, finding creative and patient methods makes long-term adherence easier.

Recognizing Seizure Triggers

Factors that can trigger seizures in some children include lack of sleep, febrile illness, high stress, missed doses, and, in some children, flashing lights (photosensitive epilepsy). Triggers are different in every child, and in some children no clear trigger is ever found. Noting possible triggers in your seizure diary can help you notice a pattern over time.
