If your child struggles with focus, sensory meltdowns, coordination, or learning — and traditional therapies haven’t moved the needle — there’s a neurological root cause that often goes unassessed: retained primitive reflexes.
The Short Answer
Retained primitive reflexes are involuntary infant movement patterns that should turn off by 12 months of age. When they remain active, they interfere with attention, coordination, sensory processing, and learning — and are a common underlying cause of ADHD-like symptoms, sensory issues, and developmental delays. They can be identified through a neurological assessment and integrated through targeted therapy. At North Lakes Chiropractic in Grand Rapids, MN, Dr. Kolby Condos addresses retained reflexes as part of a 1–2 week neuro intensive program.
What Are Primitive Reflexes?
Primitive reflexes are automatic, involuntary movement patterns that every baby is born with. They originate in the brainstem — the most primitive part of the brain — and serve specific survival purposes during infancy: helping a baby be born, find food, breathe, and develop early motor patterns.
These reflexes are designed to be temporary. As a baby moves, plays, rolls, crawls, and explores during the first year of life, the higher centers of the brain mature. As they mature, they take over control and the primitive reflexes “integrate” — meaning they switch off and stop influencing movement and behavior.
Most primitive reflexes should be fully integrated by 12 months of age. When they’re not, they continue running in the background — driving involuntary responses that interfere with the higher-level skills the child is trying to develop.
What Does “Retained” Mean?
A retained primitive reflex is one that stayed active past the developmental window when it should have switched off. The reflex is still firing automatic responses to sensory input — but the child is now 4, 7, or 12 years old, trying to sit at a desk, read a book, or regulate emotions in a noisy environment.
Imagine trying to drive a car while someone keeps grabbing the steering wheel every few seconds. That’s what a retained reflex does to a child’s nervous system. It pulls attention, triggers movement, or creates a stress response — even when the child is trying to do something completely different.
This is why retained reflexes are often misidentified as ADHD, anxiety, dyslexia, clumsiness, or a behavior problem. The behavior is real. But the cause is neurological, not behavioral.
Signs of Retained Primitive Reflexes in Children
No single sign confirms retained reflexes — but parents often notice clusters of these issues:
Difficulty sitting still or constantly fidgeting
Trouble paying attention, easily distracted
Sensory sensitivities — to textures, sounds, lights, or clothing tags
Sensory meltdowns or emotional outbursts disproportionate to the trigger
Poor balance, coordination, or clumsiness
Awkward pencil grip or messy handwriting
Trouble crossing the midline of the body
Reading struggles, skipping words, or losing place on the page
Motion sickness
Bedwetting past age 5
Toe-walking
“W-sitting” past toddler years
Anxiety, especially in new environments
Trouble with team sports or learning new physical skills
If you recognize several of these in your child — especially alongside a diagnosis of ADHD, autism, sensory processing disorder, or a learning disability — retained reflexes may be a piece of the picture that hasn’t been evaluated.
The 5 Most Commonly Retained Primitive Reflexes
There are more than a dozen primitive reflexes, but these five are the most clinically significant and the ones we assess most often at North Lakes Chiropractic:
Reflex #1: Moro Reflex
Normally integrated by: 4 months
When retained, you may see:
Heightened anxiety and emotional reactivity
Easily startled, hypersensitive to sound or light
Sensory overload and meltdowns
Difficulty adapting to change
Chronic “fight-or-flight” state
Poor impulse control
Reflex #2: Asymmetrical Tonic Neck Reflex (ATNR)
Normally integrated by: 6 months
When retained, you may see:
Handwriting difficulties and awkward pencil grip
Trouble crossing the body’s midline
Difficulty with reading and tracking words across a page
Poor hand-eye coordination
Struggles with throwing, catching, and copying from the board
Reflex #3: Symmetrical Tonic Neck Reflex (STNR)
Normally integrated by: 9–11 months
When retained, you may see:
Poor posture, slumping at desks
Difficulty sitting still — wrapping legs around chairs, W-sitting
Trouble with focus, especially during seated work
Skipped or limited crawling as an infant
Difficulty with eye tracking between near and far distances
Reflex #4: Tonic Labyrinthine Reflex (TLR)
Normally integrated by: 3.5 years
When retained, you may see:
Poor balance and coordination
Toe-walking
Motion sickness
Poor sense of time, space, and rhythm
Weak muscle tone
Difficulty judging distances
Reflex #5: Spinal Galant Reflex
Normally integrated by: 9 months
When retained, you may see:
Constant fidgeting, especially in chairs
Inability to tolerate clothing tags or waistbands
Bedwetting past age 5
Poor concentration and short-term memory
Hip rotation when walking
What Causes Primitive Reflexes to Be Retained?
Retained reflexes are usually the result of interrupted neurological development — something that disrupted the normal sequence of movement and experience that helps the brain mature past the brainstem stage. Common causes include:
Birth trauma — long or difficult labor, use of forceps or vacuum extraction, cord wrap, or fetal distress
Cesarean delivery — particularly when the baby missed the sensory pressure of passing through the birth canal
Limited tummy time during infancy
Skipped or limited crawling — crawling is a critical developmental milestone that helps integrate several reflexes
Chronic ear infections affecting the vestibular system during development
Early or prolonged use of containers — bouncers, walkers, and seats that restrict natural movement
Head injuries or concussions
Significant illness during the first year of life
Chronic stress on the developing nervous system
An important note for parents: Retained reflexes are not anyone’s fault. Many of the causes listed above are entirely outside a parent’s control — and even when they’re not, no parent could be expected to know what developmental window every infant movement is supporting. What matters is recognizing the pattern now and addressing it.
How Retained Reflexes Connect to ADHD, Autism, and Sensory Processing
One of the most important things we’ve learned in over a decade of pediatric functional neurology is that retained reflexes underlie many of the diagnoses children receive. They don’t replace those diagnoses — but they often explain why certain symptoms exist and why other therapies haven’t fully resolved them.
Retained Reflexes and ADHD
A child with a retained Moro reflex lives in a low-grade stress response — startling easily, struggling to filter sensory input, and reacting impulsively. A retained Spinal Galant makes sitting still nearly impossible. A retained STNR makes seated focus exhausting. Together, these create exactly the symptom picture that gets labeled ADHD. Addressing the reflexes can resolve many of those symptoms without medication.
Retained Reflexes and Autism
Children on the autism spectrum often have multiple retained reflexes that amplify sensory sensitivities and make regulation harder. Integrating these reflexes doesn’t change who a child is — but it removes a layer of neurological noise that’s been making everything else harder.
Retained Reflexes and Sensory Processing Disorder
Sensory processing problems are almost always tied to retained reflexes — particularly the Moro, TLR, and Spinal Galant. When the brain can’t filter input properly because the brainstem keeps firing, every sound, texture, and movement becomes too much.
Retained Reflexes and Learning Disabilities
Reading struggles, handwriting problems, and difficulty copying from the board often trace back to a retained ATNR or STNR. The child isn’t lazy or unintelligent — their nervous system is fighting them every time they pick up a pencil or look up at the whiteboard.
How We Assess and Treat Retained Reflexes at North Lakes Chiropractic
Dr. Kolby Condos is a board-certified chiropractic neurologist (DACNB) with over a decade of clinical experience and thousands of hours of post-doctoral training in pediatric neurodevelopmental disorders. Reflex assessment is a core part of every comprehensive evaluation we do.
Step 1: Comprehensive Neurological Assessment
Before any treatment begins, Dr. Condos performs a detailed evaluation that tests each primitive reflex individually alongside vestibular function, visual processing, motor skills, and sensory integration. This identifies which specific reflexes are retained and how strongly they’re influencing your child.
Step 2: Targeted Reflex Integration in a Neuro Intensive Format
Reflex integration requires consistent, repeated input to the nervous system. This is why weekly therapy often produces slow or limited results — the spacing between sessions doesn’t give the brain enough signal to rewire.
The neuro intensive format we use at North Lakes delivers 1–2 hours of focused therapy daily for 1–2 weeks. This concentrated approach provides the repetition the nervous system needs to integrate retained reflexes — often producing changes within the first week that families notice in real-life behavior.
Step 3: Combined Therapies for Whole-System Change
Reflex integration is never done in isolation. Each session combines:
Primitive reflex remediation exercises — specific movement patterns that recreate the developmental sequences the brain needs to integrate each reflex
Vestibular therapy to support balance and spatial processing
Vision therapy for visual-motor integration
Proprioceptive therapy for body awareness and sensory regulation
Low-level laser therapy to support neurological repair
Gentle chiropractic adjustments to optimize nervous system function
Step 4: Home Exercises and Follow-Up
At the end of the intensive program, families leave with a home exercise plan to continue supporting integration. Many families return every 3–6 months for follow-up intensives as new developmental layers come into focus.

Frequently Asked Questions
At what age can primitive reflex integration be done?
Reflex integration can be done at any age, including in adults. Treatment is generally faster and more efficient in younger children because their nervous systems are more adaptable — but Dr. Condos has worked with teenagers and adults to successfully integrate retained reflexes.
Will my child outgrow retained reflexes on their own?
Generally, no. By the time a child is past the early developmental window, retained reflexes won’t integrate without specific input. The good news is that the right neurological exercises can integrate them at any age.
How quickly will we see results?
Families often notice changes within the first week of the intensive program — better sleep, calmer mornings, less reactivity, improved focus. Bigger functional changes (academic performance, sports coordination, social comfort) continue to develop in the weeks and months following the program as the integrated reflexes free up higher brain function.
Does my child need to be diagnosed with something to come in?
No diagnosis is required. Many parents bring their child in because something feels off — the child is bright but struggles, or hits milestones late, or melts down in ways that don’t match their age. A neurological assessment can clarify what’s happening regardless of whether a label is attached.
Is reflex integration covered by insurance?
Coverage varies. Contact our office at (218) 999-7006 to discuss insurance and payment options for the neuro intensive program.
We don’t live in Grand Rapids — is travel practical?
Yes. Families travel to us from the Twin Cities, Duluth, Rochester, and throughout Minnesota — and beyond. The 1–2 week format is specifically designed to make a single concentrated trip viable rather than requiring weekly drives.
