Take seizure concerns seriously without diagnosing at home

Parents may wonder about seizures when a child stares, zones out, falls, has unusual movements, loses awareness, wakes confused, regresses, or has episodes that look different from their usual autistic traits.

Sometimes the answer is not seizure. It may be deep focus, shutdown, sleepiness, tics, sensory overload, fainting, migraine, anxiety, medication effects, or ordinary daydreaming.

But seizure concerns should not be dismissed just because a child is autistic.

The American Academy of Pediatrics clinical report on autism notes that autistic children have increased seizure risk, while also stating that EEG is not recommended as a routine baseline test for every autistic child when there is no seizure concern, atypical regression, or other neurological symptom.

That balance is the point: do not panic-screen everyone, and do not ignore concerning episodes.

Get emergency help for seizure danger signs

CDC seizure first-aid guidance says to call 911 if a seizure lasts longer than 5 minutes, another seizure starts soon after the first, the person has trouble breathing or waking up, the person is injured, the seizure happens in water, or the person has never had a seizure before.

During a seizure, CDC advises staying with the person, keeping them safe, timing the seizure, turning them gently on their side if lying down, and not putting anything in the person's mouth.

If your child has a diagnosed seizure disorder, follow their seizure action plan. If this is new or severe, seek emergency care.

Seizures may not look like shaking

CDC explains that seizures can involve staring, confusion, loss of awareness, falling, shaking, twitching, chewing movements, hand movements, or changes in behavior or sensation.

For parents, the task is not to name the seizure type. The task is to document what happened and get appropriate medical input.

Staring spell, attention, shutdown, or seizure?

These questions can help a clinician:

  • Can the child be interrupted by voice, touch, or a preferred item?
  • Does the episode look the same each time?
  • How long does it last?
  • Is there eye blinking, lip smacking, chewing, hand movement, stiffening, jerking, or loss of tone?
  • Is the child confused or exhausted afterward?
  • Does it happen during any activity or mostly during boredom?
  • Did it occur with fever, illness, sleep loss, flashing lights, stress, or medication change?
  • Is there injury, falling, loss of bladder control, or color change?

Do not use this list to diagnose. Use it to make the appointment more useful.

What to record safely

Write down:

  • date and time;
  • duration;
  • what the child was doing before;
  • responsiveness;
  • movements;
  • breathing or color change;
  • injury;
  • recovery time;
  • illness or fever;
  • sleep loss;
  • medication changes;
  • whether the episode happened before.

Video can help, but only if the child is safe and another adult can record. Safety comes first.

What an EEG can tell you

An EEG records electrical activity in the brain during the test. It may show patterns that support a seizure diagnosis, especially if the episode is captured or if there are relevant abnormalities.

An EEG can be useful when the history suggests seizures, atypical regression, late or unusual language loss, or other neurological concerns.

What an EEG cannot tell you

An EEG does not diagnose autism.

One normal routine EEG does not rule out every possible seizure disorder, especially if episodes are infrequent or occur during sleep.

An abnormal EEG does not automatically prove that every behavior, staring spell, or regression is caused by seizures. Results must be interpreted with the child's history and symptoms.

Parents should ask what the test is trying to answer before agreeing to it.

School and caregiver planning

If a child has diagnosed seizures or active seizure concern, ask the medical team and school about:

  • a written seizure action plan;
  • emergency contacts;
  • when to call 911;
  • rescue medication instructions if prescribed;
  • staff training;
  • water, climbing, bathing, and field-trip safety;
  • privacy and dignity after an episode;
  • how episodes will be documented.

Never let school rely on "we will know what to do" if the risk is real.

Questions for the clinician

  • Do these episodes sound concerning for seizures?
  • Should we see a pediatric neurologist?
  • Is an EEG indicated, and what kind?
  • Would sleep EEG or longer monitoring ever be needed?
  • What should we do if another episode happens?
  • What should school document?
  • Could sleep, migraine, fainting, tics, medication, anxiety, or shutdown explain the events?
  • What emergency signs should we watch for?
