Why Aren’t Schools Checking for Retained Primitive Reflexes—and Why Aren’t Parents Being Told?

When a child struggles in school, whether with reading, writing, focus, or coordination, parents are often told it’s just a developmental delay, ADHD, dyslexia, or a behavioural issue. But what if there’s an underlying cause that is rarely checked for? One that could be addressed early on to prevent years of frustration?

Primitive reflexes and their connection to neurodiversity

Enter retained primitive reflexes.

What Are Primitive Reflexes?

Primitive reflexes are automatic movements babies are born with to help them survive and develop. These include the Moro reflex (startle reflex), the ATNR (asymmetrical tonic neck reflex), and others. Normally, these reflexes integrate, meaning they go ‘dormant’, as the brain matures and higher-level motor and cognitive skills take over. But in some children, these reflexes remain active beyond infancy, interfering with their ability to learn, focus, and even control their emotions.

The Hidden Link to Learning and Behavioural Challenges

Retained primitive reflexes can contribute to:

• Difficulty with reading and writing

• Poor coordination and balance

• Sensory processing issues

• Hyperactivity and attention struggles

• Emotional dysregulation

For example, a retained ATNR can make it hard for a child to cross the midline of their body, which is crucial for reading and writing. The Moro reflex, if retained, can keep a child in a heightened state of fight-or-flight, making concentration and emotional regulation difficult.

Why Aren’t Schools Checking for This?

Despite the well-documented impact of retained reflexes, most schools don’t screen for them. Pediatricians rarely bring them up. Instead, children are often labeled with ADHD or learning disabilities, and interventions focus on managing symptoms rather than addressing a potential root cause.

What Parents Can Do

1. Get informed – Learn about primitive reflexes and their effects.

2. Request a screening – Neurodevelopmental therapists, developmental optometrists, and some chiropractors can assess for retained reflexes.

3. Do targeted exercises – Simple movements can help integrate these reflexes and improve function.

The earlier these reflexes are identified and integrated, the easier it is for children to reach their full potential. If we want to truly support struggling students, it’s time for schools and medical professionals to bring primitive reflex screening into the conversation.
