Neuroinflammation in Kids: A Hidden Factor in Autism, Seizures, and Developmental Delays

San Diego kid chiropractor

If you're a parent searching for answers about how to help your child with ASD or seizures, or why your child struggles with behavior, focus, or development—you’re not alone. More families than ever are seeking out pediatric specialists to uncover what’s really going on beneath the surface.

One of the most important (but overlooked) pieces of the puzzle is something called neuroinflammation—a hidden force that may be driving many of the challenges faced by kids with ASD (Autism Spectrum Disorder), sensory processing issues, ADHD, and more.

Let’s break down what neuroinflammation is, why it matters, and how our San Diego pediatric chiropractic practice uses low-level laser therapy and neurologically-focused chiropractic care to help.

What Is Neuroinflammation?

Neuroinflammation damages healthy brain cells, disrupts the way neurons communicate and interferes with proper brain development and function.

You’ve probably heard of inflammation—like when an injury causes swelling, redness, or pain. It’s your immune system’s way of protecting the body.

Now imagine that kind of immune response happening inside your child’s brain or nervous system. That’s neuroinflammation.

The brain has its own immune system, made up of cells like microglia and astrocytes. These act like security guards—always monitoring for danger and cleaning up damage. When activated (due to infection, injury, or even emotional stress), these cells release inflammatory molecules like cytokines.

In short bursts, this is helpful.

But when neuroinflammation becomes chronic, it can:

  • Disrupt how brain cells communicate

  • Interfere with healthy brain development

  • Lead to long-term changes in behavior and cognition

This is particularly relevant in children with ASD, seizures, developmental delays, and other neurodevelopmental disorders.

Autism, Seizures, and the Role of Inflammation

Current research links chronic brain inflammation with:

  • Autism Spectrum Disorder (ASD) in kids

  • Seizures and epilepsy in children

  • ADHD and sensory processing challenges

  • Learning difficulties and emotional dysregulation

In fact, several studies have shown that children with ASD often exhibit signs of ongoing neuroinflammation in key areas of the brain responsible for communication, emotional regulation, and social interaction.

In the case of seizures in kids, inflammation has been shown to increase excitability in the brain’s neurons—making seizures more likely and more severe. Left unchecked, this creates a cycle of inflammation → seizure → more inflammation.

What Neuroinflammation Looks Like at Different Ages

Neuroinflammation can affect children differently depending on their age and stage of brain development. Recognizing these signs early can help parents seek the right support.

In Infants and Toddlers

  • Trouble sleeping or staying asleep

  • Extreme irritability or inconsolable crying

  • Developmental delays (not rolling, crawling, or walking on time)

  • Low muscle tone or "floppy" limbs

  • Feeding challenges or poor latch

  • Unusual head shape or slow head growth

In Preschoolers

  • Language delays or regression

  • Poor eye contact

  • Difficulty with transitions or changes in routine

  • Sensory sensitivities

  • Frequent meltdowns or emotional outbursts

  • Seizure onset or unusual motor movements

In School-Age Children

  • Struggles with focus, learning, or memory

  • Anxiety or mood swings

  • Social difficulties

  • Digestive complaints (constipation, food sensitivities)

  • Trouble with coordination or motor planning

Early or chronic stress will cause an inflammatory response in the brain that can cause other health problems in kids due to neuroinflammation.

How Chronic Stress Makes Things Worse

You might think of stress as “just emotions,” but it’s much more than that—especially in developing children.

Chronic or early life stress can:

  • Keep the brain’s immune cells on high alert (a state called “priming”)

  • Lower the brain’s ability to regulate itself

  • Recruit more immune cells from outside the brain (like from the gut or bone marrow)

  • Make future stressors—even small ones—trigger exaggerated immune responses

This makes your child’s brain more vulnerable to future injuries or infections, and more likely to stay in a cycle of chronic neuroinflammation.

It’s no wonder that parents of children with ASD in kids or seizure disorders often report that regressions, flare-ups, or new symptoms follow periods of emotional, physical, or environmental stress.



The Mitochondria Connection

If you’ve read our post on Mitochondrial Dysfunction in Children, you already know that mitochondria are the body’s energy producers.

When mitochondria don’t function well:

  • Brain cells run low on energy

  • Oxidative stress increases

  • Neuroinflammation becomes harder to shut off

This creates the perfect storm for children with autism, epilepsy, and other neurologically complex conditions.

Low-Level Laser Therapy (LLLT): A Breakthrough for Brain Inflammation

Low-level Laser Therapy reduces neuroinflammation found in many neurological conditions such as autism spectrum disorder, seizures and neurodevelopment disorders.

Low-Level Laser Therapy, also called photobiomodulation, is a non-invasive, FDA-cleared treatment that uses specific wavelengths of light to target inflammation at the cellular level.

As pediatric chiropractors in San Diego, we use Erchonia Class II lasers that are safe, painless, and effective for kids—even babies.

LLLT works by:

  • Stimulating mitochondria to produce more ATP (cellular energy)

  • Reducing harmful cytokines like IL-1β and IL-6

  • Shifting microglia into a repair mode, reducing chronic activation

  • Improving overall brain energy metabolism

  • Helping regulate seizure activity by calming overexcited neurons

Research has shown that LLLT may reduce the severity and frequency of seizures in children while improving cognitive and behavioral outcomes in those with autism spectrum disorder.

How Neurologically-Focused Chiropractic Care and LLLT Work Together to Reduce Neuroinflammation

Pediatric chiropractic care reduces nervous system stress, allowing your child’s body to heal and thrive.

At Sprout Family Chiropractic, we take an integrative approach to helping children with autism, seizures, and developmental challenges. Two of our most effective tools—neurologically focused chiropractic care and low-level laser therapy (LLLT)—work hand in hand to calm the nervous system and reduce brain inflammation.

Here’s how this powerful combination works:

Chiropractic Care Regulates the Stress Response

Chronic stress is a major driver of neuroinflammation in kids. When the nervous system is stuck in a fight-or-flight state, the body:

  • Suppresses healing and digestion

  • Keeps immune cells in a chronically activated state

  • Loses the ability to turn off inflammatory signals

Gentle chiropractic adjustments help restore balance in the autonomic nervous system, allowing the body to move into a healing state and reduce inflammatory triggers at their source.

Vagus Nerve Activation: Dual Support from Adjustments + LLLT

The vagus nerve is the body's master anti-inflammatory regulator—and it’s often underactive in children with ASD, seizures, or sensory dysregulation.

  • Chiropractic adjustments (especially in the upper neck region) help stimulate vagal tone through mechanical input to the brainstem.

  • LLLT complements this by stimulating mitochondria in the vagus nerve pathway, improving cellular energy and further calming inflammatory activity.

Together, these therapies help improve vagus function—resulting in better digestion, calmer behavior, improved sleep, and decreased inflammation.

Better Sleep, Sensory Regulation, and Brain Function

Children with chronic inflammation often struggle with:

  • Poor quality sleep (which impairs brain detox and repair)

  • Sensory overwhelm (which keeps the nervous system in constant alert)

  • Mood, focus, and behavior regulation

Chiropractic care helps reset the nervous system, improve brain-body communication, and calm overactive responses.

LLLT works at the cellular level to:

  • Decrease inflammatory signaling

  • Boost ATP production

  • Support healing in inflamed brain regions

This creates a feedback loop of regulation, where the nervous system becomes more resilient and less reactive over time.

Why We Combine Both at Sprout Family Chiropractic

On their own, each of these therapies is powerful. But together, they:

  • Address both the structural and cellular drivers of neuroinflammation

  • Support both top-down (brain to body) and bottom-up (body to brain) communication

  • Create a more complete, individualized plan for long-term nervous system healing

This is why we often recommend both LLLT and chiropractic care as part of your child’s custom care plan—because the nervous system doesn’t heal in isolation.

What You Can Do at Home to Decrease Neuroinflammation

While professional care is a key part of calming neuroinflammation, there’s also a lot you can do at home to support your child’s brain health naturally.

1. Prioritize Sleep

Deep sleep is when the brain detoxifies, heals, and clears inflammation. Create a consistent bedtime routine, reduce screen time before bed, and use blackout curtains or white noise if needed.

2. Nourish the Brain

Focus on anti-inflammatory foods:

  • Omega-3 rich sources like wild salmon, flax, or chia

  • Leafy greens, berries, and colorful vegetables

  • Reduce processed sugars and artificial dyes

Work with a holistic pediatric provider if your child is on a restricted diet.

3. Support the Gut

A healthy gut helps regulate inflammation in the brain. Incorporate:

  • Probiotic-rich foods (like sauerkraut or yogurt)

  • Prebiotic fiber (bananas, oats, apples)

  • Adequate hydration and regular bowel movements (constipation is often a red flag for inflammation and nervous system dysregulation)

4. Create Calm Through Connection

Frequent stress increases neuroinflammation. Build in small daily moments of connection—cuddles, nature walks, or reading together. Simple, predictable routines help regulate the nervous system.

5. Movement is Medicine

Gentle, regular movement like play, swinging, climbing, or bouncing on a therapy ball supports lymphatic flow, vagus nerve function, and reduces inflammatory signals in the brain.

6. Reduce Environmental Stressors

  • Choose non-toxic cleaning and body products

  • Limit EMF exposure by turning off Wi-Fi at night

  • Minimize exposure to artificial fragrances and pesticides

These small, consistent steps can help create an internal environment where your child’s brain has the best chance to heal and thrive.
