Febrile Seizures Symptoms and Conditions

What Are the Symptoms and Types of Febrile Seizures?

The symptoms of a febrile seizure can be extremely distressing for a parent to witness, but understanding the physical presentation is the first step in providing correct care.
These seizures are triggered by a fever, often rising above 38.0°C (100.4°F). Because the seizure is a result of temporary electrical instability in the brain, it usually follows a specific pattern of onset and recovery.

Symptoms are generally classified into two categories: Simple and Complex. Distinguishing between these is vital for doctors to determine the necessary level of follow-up care.

Loss of Consciousness

At the very start of the seizure, the child will lose consciousness. They will not respond to their name, touch, or being shaken. This can happen suddenly, and the child may fall if they were standing or sitting.

Tonic Phase (Stiffening)

The child’s muscles may suddenly tighten and stiffen. Their back may arch, and their arms and legs may become rigid. This is often the phase where the child may let out a brief moan or cry as the air is pushed out of their lungs.

Clonic Phase (Rhythmic Jerking)

This is the most recognizable symptom. The child’s arms, legs, and sometimes facial muscles will jerk or twitch rhythmically. This movement is involuntary and cannot be stopped by holding the child.

"Sunsetting" or Rolling Eyes

The eyes may roll back into the head so that only the whites are visible, or they may become fixed in a stare. Some children may experience “sunsetting” eyes, where the gaze is driven downward.

Breathing Changes and Cyanosis

During the seizure, the child’s breathing may become irregular or temporarily stop. This can cause cyanosis, a bluish tint around the mouth or fingernails. While frightening, this is usually temporary and resolves once the jerking stops.

Foaming at the Mouth

Increased salivation is common during a seizure. This can appear as “foaming” at the mouth. It is important to remember that the child is not “choking on their tongue,” but simply unable to swallow the excess saliva.

Loss of Bladder or Bowel Control

Because the brain temporarily loses control over the muscles, the child may involuntarily urinate or have a bowel movement during the episode.

Duration of the Episode

Simple Febrile Seizure: Typically lasts from a few seconds to under 15 minutes (most are over in less than 5 minutes).

Complex Febrile Seizure: Lasts longer than 15 minutes. The duration is a key symptom that doctors use for classification.

Focal vs. Generalized Movements

Generalized: The shaking occurs all over the body (typical of simple seizures).

Focal: Only one arm, one leg, or one side of the face twitches. This “localized” shaking is a hallmark of a complex febrile seizure.

Postictal State (The Recovery Phase)

Immediately after the seizure ends, the child will enter the “postictal” state. Symptoms include:

Extreme drowsiness or deep sleep.

Confusion or irritability upon waking.

Temporary weakness in the limbs. This phase can last from a few minutes to an hour.

FREQUENTLY ASKED QUESTIONS

Is my child in pain during the seizure?

No. Because the child is unconscious, they do not feel pain or distress during the seizure. The primary danger is injury from falling or hitting nearby objects.

 The muscles around the chest stiffen during the tonic phase, which can limit oxygen flow for a few seconds. Once the seizure ends, normal breathing resumes quickly.

Even seizures lasting up to 30 minutes (status epilepticus) rarely cause permanent brain damage in previously healthy children, though they require immediate medical intervention.

 No. It is physically impossible to swallow your tongue. You should never put anything in the child’s mouth, as this can cause tooth damage or a choking hazard.

 If a second seizure occurs within 24 hours, it is classified as a “complex” febrile seizure and requires a more detailed medical evaluation.
