Neurodevelopment and SEND: going beyond the label

Most of the families who come to Think Thrive already have a name for what their child is experiencing. ADHD. Dyslexia. Dyspraxia. Autism spectrum condition. Sensory processing disorder. Sometimes several of these sit alongside one another. The diagnosis has usually been hard-won, arriving after months or years of waiting, advocating, and being told to wait a little longer.

I want to be clear from the outset: I am not here to question the value of diagnosis. A diagnosis opens doors. It gives families language, it triggers access to support, and it tells a child something important about themselves that is not a character flaw or a failure of effort. For many families, finally having a name is a profound relief.

But a diagnosis is a description, not an explanation. It tells us what a child's profile looks like. It does not always tell us why that profile exists, or what the nervous system is doing underneath it. That is the question neurodevelopmental assessment tries to answer.

What a label can and cannot do

Consider two children, both of whom have a diagnosis of ADHD. One is impulsive and physically restless, struggles to sit at a desk, and exhausts teachers with their constant movement. The other is inattentive and quietly withdrawn, appears to be daydreaming, and loses the thread of conversations. Both meet the diagnostic criteria. Both have the same label. But the neurological picture underlying each child's presentation may be quite different, and so the support that actually helps them will be different too.

Diagnostic assessment is designed to identify patterns that meet clinical thresholds. It is a necessary and important process. But it is not designed to ask: which parts of this child's nervous system are not yet fully developed, and what can we do about that? Neurodevelopmental assessment asks a different set of questions, and in doing so, it often reveals things that are both actionable and, in the best cases, genuinely changeable.

The neurodevelopmental layer

Neurodevelopmental therapy, as I practise it through the INPP method and Tomatis® sound therapy, is grounded in the understanding that the brain and nervous system develop in a particular sequence, and that when any part of that sequence is disrupted or incomplete, the effects ripple outward into everything the child does.

Primitive reflex retention is one of the most significant of those disruptions. These are the automatic movement responses that develop in the womb and are essential for survival in the first months of life. Normally, as the brain matures, these reflexes are inhibited and replaced by more sophisticated, voluntary movement patterns. When that inhibition does not happen fully, the nervous system continues to operate, in part, as if it were still in an earlier stage of development.

The implications of this are far-reaching. Retained primitive reflexes affect balance, coordination, posture, visual tracking, sensory processing, and emotional regulation. In a child who has already received a diagnosis, these effects are often simply absorbed into the existing label. The anxiety is attributed to autism. The poor handwriting is attributed to dyspraxia. The inability to sit still is attributed to ADHD. The label explains the behaviour, and so the question of what is driving the behaviour stops being asked.

Where the profiles overlap

Research over the past few decades has consistently found high rates of primitive reflex retention in children with a range of SEND profiles. Children with dyslexia commonly show a retained Asymmetrical Tonic Neck Reflex, which affects the ability to track across a page and coordinate the two sides of the body. Children diagnosed with ADHD frequently show a retained Moro reflex, keeping the nervous system in a state of heightened alert and making it genuinely difficult to regulate attention and emotion. Children with dyspraxia often show multiple retained reflexes affecting muscle tone, balance, and spatial awareness.

This is not to suggest that reflex retention causes these conditions, or that addressing it will make a diagnosis disappear. The relationship is more nuanced than that. What it does suggest is that for many children with SEND profiles, there is an additional layer of neurological immaturity that is making everything harder, and that this layer can be worked with directly.

The same principle applies to the auditory system. Many children who struggle with reading, attention, or language processing have auditory profiles that show the listening system is working inefficiently. The Tomatis® Listening Test makes this visible. A child who has spent years in speech and language therapy, or who has been given strategies for comprehension difficulties, may have an underlying auditory processing pattern that has never been assessed or addressed.

What neurodevelopmental assessment adds

A neurodevelopmental assessment at Think Thrive begins with a detailed developmental history. This covers the period from pregnancy and birth through to the child's current presentation, and it is often in this history that the first significant patterns emerge. Birth complications, delayed motor milestones, early sensory sensitivities, difficulties with crawling or balance: these are not incidental details. They are part of the neurological story.

The assessment then involves standardised testing of primitive reflexes, balance, coordination, and, where appropriate, the Tomatis® Listening Test. The results are interpreted together, not in isolation. What emerges is a picture of how the child's nervous system is functioning at the level of its foundations, and where those foundations are incomplete.

From there, a programme is designed around the individual child. For INPP work, this takes the form of a daily movement sequence that mirrors the developmental stages the nervous system needs to revisit. It is not exercise for its own sake. It is a structured, evidence-informed process of neurological maturation, done at home for around ten minutes a day and reviewed at regular intervals. For Tomatis work, sessions take place at the practice using the Maestro headset, following a programme structure calibrated to the child's listening profile.

A different kind of alongside

One of the things I want families to understand is that neurodevelopmental therapy is not a replacement for the support a child already has. It sits alongside it. A child who is working with a specialist teacher, receiving speech and language therapy, or accessing school-based SEND support can continue to do all of those things. What neurodevelopmental work can do is change the conditions under which all of that other support is received.

When a child's nervous system is less burdened by retained reflexes, when they are not having to work so hard just to sit upright or track across a page or manage a startle response to unexpected noise, the capacity for learning opens up. The same strategies that previously had limited traction can start to land differently. Progress that has felt stuck can begin to move.

It is not a quick fix, and I would never present it as one. These are developmental processes, and they take time. But for children who have been stuck at the same point for a long time despite doing everything right, a neurodevelopmental assessment is often where the missing piece of the picture finally appears.

A note for parents who are just beginning

If your child has recently been diagnosed, or if you are in the middle of a lengthy assessment process, the prospect of yet another type of appointment may feel like too much. I understand that. There is no obligation to do everything at once, and there is no single correct path through this.

What I would say is that an initial conversation costs nothing. It is not a commitment to a programme, and it is not a judgment on anything you have or have not done. It is simply an opportunity to understand whether a neurodevelopmental lens might add something useful to the picture you already have of your child.

Most parents leave that conversation with a clearer sense of what is happening and why. That clarity, even on its own, can make an enormous difference.
