Autism and Seizures: What Parents Need to Know About the Overlap

A real conversation for parents who feel like something more is going on

If you’re raising a child with Autism spectrum disorder, you already know how layered everything can feel.

And at some point, many parents start asking:

“Is this autism… or could something else be happening too?”

This is where the conversation around seizures comes in.

At West Wave Neuro, this is something we see more often than people realize and it’s not talked about enough.

The Overlap Between Autism and Seizures

Here’s what most people don’t know:

Children with autism have a higher risk of seizures compared to the general population.

That doesn’t mean every child on the spectrum will have them.But it does mean we need to pay attention when something feels different.

Seizures can show up in ways that don’t always look like what you’d expect.

Not all seizures are dramatic.

Some are quiet. Subtle. Easy to miss.

Why Is There a Higher Risk?

This is the part parents are rarely told—and it actually helps everything make more sense.

There isn’t just one reason. It’s usually a combination of how the brain is developing and functioning.

1. Brain Connectivity Differences

In children with autism, the way different parts of the brain communicate can be different.

Sometimes there is:

• Overactivity in certain areas

• Under-connectivity in others

That imbalance can make the brain more prone to irregular electrical firing, which is what seizures are.

2. Excitatory vs. Inhibitory Imbalance

The brain relies on a balance between signals that activate (excite) and signals that calm (inhibit).

In some children with autism:

• There may be too much excitatory activity

• Or not enough inhibitory control

That imbalance can increase the likelihood of seizure activity.

3. Genetic Factors

Some of the genes associated with Autism spectrum disorder are also linked to:

• Epilepsy

• Abnormal brain signaling

So sometimes the overlap is built into how the brain developed from the start.

4. Developmental Timing

The brain is rapidly developing in early childhood.

If there are disruptions in how neural networks form:

• It can affect communication, behavior, and sensory processing (autism)

• And also increase susceptibility to seizures

5. Sleep and Brain Activity

Sleep plays a huge role in brain regulation.

Many children on the spectrum struggle with sleep, and:

• Poor or disrupted sleep can trigger abnormal brain activity

• Some seizure activity actually only shows up during sleep

This is a big reason we look deeper when nighttime behaviors are involved.

What Do Seizures Actually Look Like in Kids with Autism?

This is where it gets tricky.

Because a lot of seizure activity can look similar to behaviors already seen in autism.

🚩 Signs to Watch For

• Staring spells where your child is unresponsive

• Sudden pauses in activity or speech

• Repetitive movements that feel different than their normal baseline

• Sudden confusion or disorientation

• Unexplained behavioral regression

• Loss of skills (speech, motor, social)

• Episodes during sleep (jerking, stiffening, waking disoriented)

• Sudden aggression or emotional shifts without a clear trigger

A big one parents tell us:

“It doesn’t feel like their typical behavior.”

That instinct matters.

Is Seizure Activity Harmful?

Short answer: it can be, depending on what’s happening and how often.

Some key things to understand:

• Repeated or untreated seizures can impact brain function over time

• Sleep-related seizure activity can disrupt brain development and rest cycles

• Even subtle, ongoing abnormal activity can affect behavior, focus, and development

But also:

👉 Not all abnormal EEG activity is dangerous👉 Not all seizures cause long-term harm

The goal is understanding what’s actually happening, not assuming the worst.

Why Diagnosis Isn’t Always Simple

Seizures in children with autism are often:

• Misinterpreted

• Missed entirely

• Or brushed off as behavioral

And standard testing doesn’t always help.

A short, in-office Electroencephalography may not catch anything—especially if:

• Events don’t happen daily

• They occur during sleep

• They’re triggered by specific environments

Why We Recommend Ambulatory EEG

At West Wave Neuro, we focus heavily on Ambulatory EEG for this exact reason.

Because we’re not just looking for a moment.We’re looking for patterns.

What makes it different:

• Monitoring over 24–72+ hours

• Capturing both awake and sleep cycles

• Observing your child in their natural environment

Why In-Home EEG Matters for Kids on the Spectrum

Let’s be real…

A clinical setting can:

• Increase anxiety

• Change behavior

• Mask what’s actually happening at home

When EEG is done in your child’s own home:

• They’re more relaxed

• Behaviors are more natural

• Sleep is more accurate

• Data is more meaningful

What Parents Should Know Going Into This

If you’re even questioning seizures, here’s what I want you to take with you:

1. You’re not overreacting

If something feels off, it’s worth looking into.

2. Not everything is “just autism”

There can be overlapping neurological activity.

3. Seizures don’t always look like seizures

Especially in kids on the spectrum.

4. There are real reasons for the overlap

This isn’t random—and it’s more common than people think.

5. Testing should match real life

The more natural the setting, the better the data.

6. Early answers matter

The sooner you understand what’s happening, the sooner you can support your child appropriately.

What the Process Looks Like With Us

We approach this differently because we know how sensitive these cases can be.

At West Wave Neuro:

• We take our time with setup

• We work with sensory needs, not against them

• Our headwraps are secure and we move at your child’s pace

• We monitor everything behind the scenes

You don’t have to manage the medical side.

You focus on your child.We handle the rest.

To wrap it up

Autism and seizures can overlap but they are not the same thing.

And when they do overlap, having the right information can change everything.

If you’re noticing:

• Regression

• Unusual episodes

• Sleep disruptions

• Behaviors that don’t feel typical

It’s okay to ask more questions.
