The Primitive Reflex Mistake Many Providers Make

One of the most important clarifications from our first Neuro Build live call of the new cohort was this:

A lot of providers are using the wrong language when they talk about primitive reflexes.

More specifically, many clinicians say they are “integrating” a reflex when what they are actually seeing is inhibition of that reflex.

That distinction matters more than most people realize.

Integration and inhibition are not the same thing

In this call, Dr. Josh broke down a concept that can immediately sharpen the way providers assess developmental cases.

Primitive reflexes are not just random movements to get rid of. They are brainstem-driven movement patterns that are meant to be present during development. In the beginning, those reflexes are part of the brain’s normal developmental process. They help stimulate the nervous system and support the growth of the cortex.

That is integration.

The reflex is present, active, and serving a purpose in development.

What providers are usually trying to create in older children is not integration. It is inhibition.

In other words, the reflex may still exist in the nervous system, but a more mature cortex should be able to suppress it. When that frontal cortical inhibition is not happening, the reflex remains visible long after it should have disappeared.

That is the clinical problem most providers are actually dealing with.

Why this changes how you think about care

If you confuse integration with inhibition, your treatment strategy can get muddy fast.

A retained reflex does not always mean the reflex itself is the problem. It often means the cortex is not doing its job well enough to inhibit the brainstem pattern. That opens up a much bigger clinical conversation.

Now you are not just asking, “How do I get rid of this reflex?”

You are asking, “Why is this child’s brain not inhibiting this reflex?”

That question leads you to better clinical reasoning.

Maybe the cortex is underdeveloped because the child has poor tone and weak motor output. Maybe neuroinflammation is interfering with higher brain function. Maybe oxygenation is poor. Maybe there are metabolic issues limiting energy production. Maybe the child never developed enough movement complexity for proper cortical maturation in the first place.

Once you start thinking this way, retained reflexes stop being isolated findings and start becoming windows into the function of the whole nervous system.

Reflexes are a sign of what the cortex is doing

One of the most helpful ways to think about primitive reflexes is this:

The reflex is not just a movement pattern. It is information.

A visible reflex tells you something about cortical control.

If a reflex is present when it should be inhibited, the frontal cortex is not managing that pattern efficiently. If a reflex is missing when it should still be helping the child develop, then the earlier developmental loop may not have been established.

That is why reflexes are so valuable clinically. They are not just something to test and document. They help you understand where the nervous system may be breaking down.

This also explains why a reflex can change quickly when the right pathway is activated. If the brain gets what it needs, whether that is better oxygenation, improved energy production, better cerebellar activation, reduced inflammation, or stronger sensory-motor input, the cortex may suddenly be able to inhibit the reflex much more effectively.

The reflex did not magically disappear. The brain started doing its job better.

Better language leads to better clinical decisions

For providers working with developmental cases, this distinction is more than semantics.

When you start using the right language, you start building the right treatment model.

You stop thinking only in terms of reflex exercises. You start thinking in terms of nervous system function, cortical maturation, and what is preventing inhibition from happening.

And that shift improves everything from assessment to care planning to parent education.

Because once you understand whether you are trying to reinforce a missing developmental pattern or inhibit a reflex that overstayed its role, your clinical reasoning becomes much clearer.

That is where better outcomes start.
