Febrile Seizures in Children: What Every Parent Should Know

Febrile seizures are seizures associated with fever that usually occur in children between 6 months and 5 years of age, without evidence of a brain infection or another neurological cause. It is usually brief and stops on its own. It typically does not cause lasting health problems or epilepsy. Knowing what to do during a febrile seizure in children and how to respond to it is important. Getting medical care is essential to determine the cause of the fever and rule out other conditions.

Febrile seizures affect approximately 2%–5% of children between 6 months and 5 years of age, making them one of the most common childhood neurological conditions.

What Are Febrile Seizures?

Febrile seizures are convulsions that happen in children with a fever. They are triggered by a rise in body temperature to 38°C (100.4°F) or higher. In many children, the seizure is triggered by the rapid rise in body temperature rather than the exact temperature itself. Febrile seizures are not caused by an infection, head injury, or other medical condition that affects the brain. According to the American Academy of Paediatrics (AAP), febrile seizures are among the most common neurological events in early childhood.

A febrile seizure in children may happen when a child has a fever for the first time. It can also happen when the child has a fever that comes back after being gone for a while. Although they can be frightening for parents and caregivers, febrile seizures rarely cause serious health problems.

What Causes Febrile Seizures?

The cause of febrile seizures is unknown. Researchers believe that they are triggered by a combination of genetic and environmental factors. The young child's developing brain is more susceptible to seizures during a fever.

Common causes of fever in children that can lead to febrile seizures include:

Viruses such as influenza, roseola, and adenovirus
Ear infections
Upper respiratory tract infections
Bacterial infections
Fever due to some vaccines. Although the risk is small, the benefits of vaccination far outweigh the risks

According to the Centers for Disease Control and Prevention (CDC), febrile convulsions after vaccination are rare.

What Are the Symptoms of Febrile Seizures?

The symptoms of febrile seizure in children may include:

Loss of consciousness
Rhythmic jerking or shaking of the arms and legs
Stiffening of the arms and legs
Rolling of the eyes
Unresponsiveness or loss of awareness
Confusion or sleepiness after the seizure

Simple febrile convulsions in children are usually brief, lasting less than five minutes. They also stop on their own without treatment.

Types of Febrile Seizures

Simple Febrile Seizures

Simple febrile seizures are the most common type of febrile convulsions. They have the following characteristics:

Last for less than 15 minutes
Whole-body movements
Only one seizure in 24 hours
Usually have a good outcome

Complex Febrile Seizures

A febrile seizure in children is considered complex if it:

Lasts longer than 15 minutes
Happens more than once in 24 hours
Only affects one side of the body

Children with complex febrile convulsions may need further testing and febrile seizure treatment.

What Should Parents Do During a Febrile Seizure?

If your child has febrile convulsions, it is important to stay calm and take the following steps:

Place the child immediately on their side on a firm surface. Stay with the child until the seizure ends.
Remove any objects that could hurt the child
Loosen any tight clothing around the child’s neck
Do not put anything in the child’s mouth
Do not try to stop the shaking
Time the seizure
Call for emergency medical help if the seizure lasts longer than five minutes, the child has difficulty breathing, or the child is not fully alert after the seizure

According to the National Institute of Neurological Disorders and Stroke (NINDS), it is important not to put anything in the child’s mouth during a seizure. This can cause injury.

How Are Febrile Seizures Diagnosed?

Febrile convulsions are diagnosed based on the child’s symptoms, medical history, and physical examination. Other tests that may be done include:

Exam to determine the cause of the fever
Blood or urine tests if needed
Lumbar puncture if meningitis is suspected
EEG or brain imaging (CT or MRI) is rarely needed and is only recommended in selected cases where another neurological condition is suspected.

According to the AAP, brain scans are usually not needed for simple febrile seizures.

Febrile Seizure Treatment

The febrile seizure treatment for febrile convulsions depends on the cause and severity of the seizure. The main goal is to treat the underlying cause of the fever and prevent further seizures.

Treatment may include:

Medications to reduce fever
Fluids to prevent dehydration
Treatment of any bacterial infections that may be present
Observation until the child has fully recovered

If the febrile convulsions are prolonged, emergency medications may be needed in the hospital. Long-term anti-seizure medications are generally not recommended after simple febrile seizures because the risks usually outweigh the potential benefits.

Can Febrile Seizures Come Back?

Yes, febrile convulsions can happen more than once. In fact, about one-third of children who have them will have another seizure. The chance of recurrence is higher if:

The child was under 18 months old when they had their first seizure
There is a family history of febrile convulsions
The first febrile seizure occurred before 18 months of age.
The fever was low when the seizure happened

Despite this, most children who have febrile convulsions do not have any long-term health problems.

Can Febrile Seizures Be Prevented?

There is no sure way to prevent febrile seizures. Fever-reducing medicines improve comfort but do not reliably prevent febrile seizures. Parents can also take steps to prevent infections that can cause fever. This includes:

Getting recommended childhood vaccines
Washing hands often
Seeking medical care for any infections
Making sure the child drinks plenty of fluids when they are sick

When Should You Seek Medical Care for Febrile Seizures?

Parents should seek medical care for febrile convulsions if:

The seizure lasts longer than five minutes
The child has trouble breathing
The seizure affects only one side of the body
The child has another seizure within 24 hours
The child has a stiff neck, vomiting, or a rash
The child is under six months old and has a fever with a seizure

Prompt medical evaluation is important to rule out other conditions that may require treatment.

Conclusion

Most febrile seizures are brief, do not cause lasting health problems, and stop on their own. Knowing what to do during a febrile seizure in children and how to respond to it is important. Getting medical care is also essential to determine the cause of the fever and rule out other conditions. Appropriate febrile seizure treatment for febrile convulsions focuses on making the child comfortable and determining the cause of the fever. Most febrile seizures stop on their own within a few minutes. Treatment mainly focuses on identifying and managing the cause of the fever rather than preventing every seizure.
