When the Brain Doesn’t Forget: Birth Trauma, TBI, ADHD and What Brain Mapping Reveals.
Hard Yarns Podcast | Featuring Lara Schulz | ADHD, Traumatic Brain Injury & QEEG
Some episodes of a podcast stay with you. This one from the Hard Yarns Podcast featuring neurotherapist Lara Schulz is one of them. Not because it is easy listening, but because it is honest in a way that clinical conversations rarely are.
The episode begins with birth stories. Two hosts describe complicated arrivals into the world: hypoxia, low oxygen, emergency intervention, limp and blue newborns who weren’t expected to thrive. Over the course of nearly two hours, Lara then maps one host’s brain live on air, walks through what the data reveals, and delivers a 100% AI-matched ADHD diagnosis with complete clinical clarity and no drama whatsoever.
As a Psychophysiologist and Family Therapist, I want to reflect on what this episode covers and why it matters for anyone who has ever wondered whether something neurological might be driving experiences they have struggled to explain.
Why Birth History Matters for Brain Assessment
Lara opens by asking about birth history. It is a question that surprises the hosts, but any QEEG clinician will recognise it as essential. Birth trauma, particularly hypoxia (oxygen deprivation at birth), is one of the most significant and underrecognised contributors to atypical brain development.
When a newborn is deprived of oxygen, even briefly, the impact on developing neural tissue can be lasting. The brain adapts and it is remarkably resilient, but adaptation is not the same as recovery. Compensatory pathways develop, certain regions work harder than they should, and others become quieter than optimal. These patterns show up decades later on a brain map.
This is why a thorough QEEG assessment at The Togetherness Project always includes a detailed birth and developmental history. The brain you are living in today has been shaped by everything that happened to it, including the circumstances of your arrival in the world.
Birth trauma is not a distant historical event. Its effects can remain present in the brain’s electrical architecture well into adulthood, and brain mapping can help us see them.
Low Voltage Brain Profiles: What They Mean
One of the most clinically interesting findings in this episode is the host’s low voltage brain profile. Lara explains this clearly: some brains produce electrical activity of smaller magnitude than average, making the signal harder to read and the brain harder to assess with standard tools.
Low voltage profiles are associated with head injury, chronic stress, and in some cases the lasting effects of birth trauma or early hypoxia. The brain has essentially learned to operate on reduced electrical energy, a kind of conservation mode. It functions, often impressively so, but at a cost. The person typically reports chronic fatigue, difficulty with sustained attention, poor sleep quality, and a persistent sense of working harder than everyone else just to keep up.
Alongside the low voltage finding, Lara identifies fast beta spindling in the frontal lobes. This pattern is associated with hypervigilance, difficulty switching off, and disrupted sleep architecture. The brain is simultaneously under-powered and over-activated: not resting when it should be, and not performing at capacity when it needs to.
A low voltage brain is not a less capable brain. It is a brain that has adapted to difficult circumstances and learned to do more with less. Neurotherapy works with that adaptation, not against it.
TBI, Head Injury, and the Brain’s Slow Wave Response
The episode covers traumatic brain injury (TBI) in meaningful depth, and this is an area I want to highlight because it remains significantly under-recognised in the Australian mental health and neurotherapy conversation.
When the brain sustains a physical injury, whether from a direct blow, a whiplash event, or oxygen deprivation, it responds by increasing slow-wave delta activity in the affected region.
This is the brain’s protective mechanism: slow the area down, reduce metabolic demand, and allow healing. The problem arises when the brain does not fully return to its pre-injury wave patterns. Persistent slow-wave activity in regions that should be running faster indicates unresolved injury, and this pattern can persist for years or even decades after the original event.
What makes this particularly relevant is how closely a TBI profile can resemble an ADHD profile. Both involve slow-wave excess, attentional difficulties, impulsivity, emotional dysregulation, and difficulties with sustained cognitive effort. Without brain mapping, the two are functionally indistinguishable from behavioural assessment alone. With brain mapping, the distinction becomes far clearer, and so does the appropriate intervention.
If you or your child have a history of head injury, falls, a difficult birth, or whiplash and have subsequently struggled with attention, mood, or cognition, a QEEG assessment is worth considering before assuming the diagnosis is purely psychiatric.
Sleep, Delta Waves, and Why Rest Isn’t Optional
Lara devotes meaningful time in the episode to sleep, specifically the role of delta waves in restorative sleep and why disruption to this pattern has such wide-ranging consequences.
Delta waves are the brain’s deep sleep rhythm. They are associated with physical restoration, immune function, growth hormone release, and memory consolidation. When the brain is not producing adequate delta during sleep, as is common in ADHD, TBI, and high-stress presentations, the person wakes unrefreshed regardless of how many hours they have been in bed. The sleep is present but it is not restorative.
Neurotherapy protocols that target delta wave production are among the most consistently impactful we use in clinical practice. Improvements in sleep quality are often the first change families and clients report, and from better sleep, almost everything else becomes more manageable.
The ERP Findings: Processing Speed and the P300
The ERP section of the episode is particularly illuminating for anyone unfamiliar with how Event-Related Potentials add depth to a QEEG picture.
In the host’s assessment, the P300 response is significantly delayed, occurring at approximately 750 milliseconds rather than the expected 300 milliseconds. The P300 reflects the speed and efficiency of executive cognitive processing, so this means the brain is taking more than twice as long as average to consciously register and respond to incoming information.
What is striking about this finding is that the host has clearly developed sophisticated compensatory strategies over many years. High performance in demanding environments is possible even with a delayed P300; it simply requires considerably more effort and results in faster depletion. The ERP data explains why someone can appear highly capable while privately finding everything exhausting. Lara handles this part of the conversation with real clinical sensitivity.
A delayed P300 is not a ceiling on potential. It is a measure of how hard the brain is currently working to achieve what comes more automatically to others. Neurotherapy can shift that baseline.
The AI Protocol and the ADHD Diagnosis
The moment many listeners will remember from this episode is the reveal: the AI-assisted EEG analysis matches the host’s brain profile to ADHD at 100%.
For some people, a formal diagnosis of any kind lands as a relief, a coherent explanation for a lifetime of experiences that never quite fit the mould. For others it raises questions. I want to be clear about what this kind of finding means in clinical practice.
The AI protocol does not diagnose in a psychiatric sense. What it does is compare the individual’s QEEG data against a database of profiles associated with specific presentations and report the degree of match. A 100% match to an ADHD profile means the brain’s electrical architecture is consistent with what is consistently observed in ADHD. It is strong confirmatory data, not a standalone diagnosis. Used alongside clinical history, behavioural presentation, and ERP findings, it contributes to a far more complete and individually tailored picture than a checklist-based assessment alone.
Lara also shares outcome data in the episode that is worth noting. Clients who have completed neurotherapy following a similar profile have shown significant reductions in ADHD symptom severity, with measurable improvements in auditory processing, focus, and relational functioning.
A Note on the Education System and Labelling
The hosts in this episode speak candidly about their experiences with the education system: the mismatch between how their brains work and what classrooms demand, the damage caused by labelling without support, and the frustration of a system that pathologises difference rather than accommodating it.
This resonates strongly with what families bring to The Togetherness Project. Children who are struggling at school are often described in terms of what they cannot do, rather than what their brain actually needs. A QEEG assessment can reframe that conversation entirely. Not by excusing difficulty, but by explaining it and pointing toward what is actually likely to help.
