The Body Keeps the Charge: Trauma, Risk, and Delinquency

Professor A.

Welcome back, everyone, to Let’s Talk About Juvenile Delinquency. I’m Professor A., and as always, joining me in the studio is my brilliant assistant, Marcus. Marcus, how are you doing today?

Marcus

I’m doing alright, Professor A. But I’m not going to lie—my mind is heavy today. I’ve been reading the news coming out of Gonzales, Louisiana over the weekend, and it’s been weighing on me.

Professor A.

Yes, the tragedy on East Caldwell Street near North Frances Avenue. On Friday, August 21, a shooting left two young people dead—seventeen-year-old Tegan Daigle and twenty-one-year-old Jared Downey.

Marcus

And the police arrested another seventeen-year-old, Joseph Appiah, from Prairieville. They charged him with two counts of first-degree murder, criminal conspiracy, eight counts of aggravated assault with a firearm, and possession with intent to distribute a Schedule 1 drug. The police immediately cited "illegal drug activity" as the factor driving the violence. And then, of course, the local advocates started calling for more "gun safety education".

Professor A.

It is a devastating loss of life. But when we look at the immediate institutional response—both from the police and the advocacy groups—we see the classic trap of the traditional juvenile justice paradigm. They focus entirely on the symptoms: the guns, the drugs, the individual choice of a "deviant" youth. They are asking the classic, pathologizing question: "What is wrong with this kid?"

Marcus

Exactly. "What’s wrong with him?" Why did he make that "choice"? But this week in our class, we are making a fundamental turn. We are shifting from that pathologizing question to a trauma-informed one: "What happened to you?" We aren't excusing the violence, but we are trying to understand the neurodevelopmental and environmental cascades that lead a seventeen-year-old to a point where pulling a trigger is what their brain tells them is necessary for survival.

Professor A.

And that shift—from "What is wrong with you?" to "What happened to you?"—is the theme of today's episode. Today, we are going to look at how chronic early life stress gets under the skin, alters the physical architecture of the brain, and systematically manufactures the very "risk" that the legal system then punishes.

Marcus

So, Professor A., let’s start with the biology. Because people hear "trauma" and they think it’s just a sad memory or an emotional state. But the research by Smith and Pollak tells us that early life stress actually rewires a child's biology. How does that happen?

Professor A.

It is a literal physical restructuring, Marcus. When a child experiences chronic and extreme stress—whether that is physical abuse, severe neglect, or the grinding instability of deep poverty—it triggers a prolonged activation of their physiological stress response systems. In a healthy brain, the hypothalamic-pituitary-adrenal, or HPA axis, releases glucocorticoids like cortisol to help us handle temporary threats. But chronic stress keeps this system turned "on" indefinitely.

Marcus

Right, and that constant toxic bath of stress hormones damages three key regions: the hippocampus, the amygdala, and the prefrontal cortex.

Professor A.

Precisely. First, the hippocampus—which is responsible for learning and memory—suffers structural damage. One of the most robust findings in developmental neuroscience is that children exposed to early life stress show significantly reduced hippocampal volume. This directly impairs their learning processes and cognitive flexibility. Second, the amygdala—the brain's threat-detection center—becomes hyper-reactive. And third, the prefrontal cortex, which controls executive functioning and impulse regulation, fails to develop typical regulatory connectivity with the amygdala. In a typically developing brain, the PFC acts as a volume dial, dampening the amygdala's alarm signals. But in a traumatized brain, that dial is broken. The amygdala fires wildly, and the PFC cannot shut it down.

Marcus

Man... that means these kids are literally living in a constant state of biological survival. And Smith and Pollak discuss how this leads to what they call "Perceptual Adaptations to Threat". For example, physically abused kids develop this intense, hyper-vigilant sensitivity to anger.

Professor A.

Yes, they require far less visual information to categorize a face as "angry" compared to non-abused peers. They also struggle to disengage their attention from hostile cues during cognitive tasks because their brains are prioritizing threat monitoring over everything else.

Marcus

And that’s the key! In an abusive or unstable home, that hyper-vigilance is highly adaptive—it keeps you alive. But when that child steps into a school, or onto a street corner, that survival mechanism becomes a massive liability. They perceive a slight shoulder bump, an awkward glance, or a neutral face as an imminent life-or-death threat.

Professor A.

Exactly. It is a biological adaptation to an unexpectable environment.

Marcus

You know, this reminds me of the hip-hop track we assigned for this week: the Geto Boys' 1991 classic, "Mind Playing Tricks on Me". Decades before the neuroimaging studies by Smith and Pollak, Scarface was describing this exact biological rewiring. Remember the opening lines? "I sit alone in my four-cornered room staring at candles / Oh shit, my mind is playing tricks on me." He describes walking down the street, constantly looking over his shoulder, seeing threats that aren't there, and his heart rate spiking. That is not just a rap lyric—that is a clinical depiction of a hyper-active amygdala and atypical prefrontal-amygdala connectivity. He is documenting the visceral, exhausting reality of living with intrusive threat-monitoring and a shattered stress-response system.

Professor A.

That is a profound connection, Marcus. Scarface is giving us the qualitative, lived evidence of what the lab is measuring with fMRI scans. The song documents the severe sleep deprivation, the hyper-vigilance, and the paranoid protective armor that trauma builds.

Professor A.

Now, let's trace how this biological rewiring translates into behavioral problems over time. This brings us to the longitudinal study by Nicole Fava and her colleagues. They looked at a sample of 480 adolescents over several years in the Michigan Longitudinal Study.

Marcus

Yeah, this paper is incredible because they build a "serial mediation model". They don't just say "adversity causes crime." They map the developmental cascade step-by-step. Professor, walk us through that pathway.

Professor A.

Well, it starts with Adverse Childhood Experiences, or ACEs, occurring before the age of eleven. As we discussed, these ACEs trigger physiological hyper-arousal. The first behavioral symptom of this biological arousal is actually sleep problems in late childhood, between the ages of nine and eleven. Because these kids are hyper-vigilant and their cortisol levels are dysregulated, they cannot fall or stay asleep.

Marcus

And sleep is the fuel for the prefrontal cortex, right?

Professor A.

Absolutely. Severe sleep deprivation actively degrades executive functioning. So, Fava and her team found that these childhood sleep problems directly predict low self-control in early adolescence, between ages twelve and fourteen. The child loses the cognitive capacity for emotional regulation and gratification delay. And finally, that deficit in self-control is what directly predicts delinquency in late adolescence, between ages fifteen and seventeen.

Marcus

It’s a literal chain reaction. ACEs lead to ruined sleep, which robs you of self-control, which leads to handcuffs. And Dylan Jackson and his colleagues supported this dose-response relationship in their study of over eleven thousand youth in the UK Millennium Cohort Study. They found that as early childhood ACEs accumulate at ages five and seven, the rate of delinquency at age fourteen climbs dramatically.

Professor A.

Yes, compared to youth with no ACEs, a child with just one ACE has a 21% higher rate of delinquency. For two ACEs, it's a 45% increase, and for three or more ACEs, the delinquency rate jumps by 66%.

Marcus

66%! That is a massive dose-response effect. And out of all the mediators they tested at age eleven—including substance use, parent-child attachment, and unstructured socializing—it was low self-control and early property misconduct that emerged as the most robust pathways.

Professor A.

But Marcus, this is where we have to challenge traditional criminological theory. If you open any standard textbook, you’ll read Gottfredson and Hirschi’s General Theory of Crime. They famously claim that low self-control is solely the product of "poor parenting"—that parents just failed to monitor and discipline their kids.

Marcus

Yeah, they basically blame the parents and ignore the biology. But the Portuguese study by Pedro Pechorro and his colleagues completely flips that on its head. They studied 388 young males and distinguished between traumatic events—like physical abuse or witnessing domestic violence—and trauma reactions, which are actual PTSD symptoms.

Professor A.

And what did they find regarding mediation?

Marcus

This is the mind-blowing part: they found that low self-control only partially mediates the relationship between traumatic events and delinquency. The events themselves still have a massive, direct, unmediated effect on conduct disorder, aggression, and crime seriousness. But when it came to trauma reactions—the internal psychological suffering, the PTSD—low self-control fully mediated the outcome.

Professor A.

Meaning that a child's internal post-traumatic suffering has no direct "choice" path to delinquency. Instead, the trauma completely erodes and shuts down their neurocognitive capacity for self-regulation. The low self-control we observe in these kids isn't a moral failure or a result of lax discipline—it is a direct pathological reaction to trauma.

Marcus

Professor A, let’s ground all of this science in a real-world case study. After you mentioned to me the podcast interview with NBA YoungBoy a few weeks ago, I watched and analyzed it. Baton Rouge superstar NBA YoungBoy—Kentrell Gaulden—talked with Funny Marco from South Korea, the interview dropped on August 11, 2026. It’s got over two million views, and honestly, it is a masterclass in everything we are studying.

Professor A.

It truly is. Here is a young man, only twenty-six years old, who is currently the first artist to surpass one hundred Gold singles, beating out Jay-Z, Drake, Kanye. Yet, his career has been completely parallel to trauma, incarceration, and systemic legal struggles. He recently permanently relocated to South Korea, telling Marco that he is "never in life" moving back to the United States because Korea is "very safe" and "clean".

Marcus

Think about that. A twenty-six-year-old Black man from Baton Rouge feels he has to flee the entire Western hemisphere just to find a "cue of safety". When we ask "What happened to you?", his childhood screams the answer. In the interview, Kentrell talks about the lack of support from his mother, Sherhonda Gaulden, and his father. His mother and father were not there for him, leaving him with a deep, systemic sense of rejection and hurt.

Professor A.

And who was his biological buffer?

Marcus

His grandmother. He says, and I quote: "My grandma used to make sure Christmas is always good. No matter how damn bad things was, Christmas, was always good.". He lived with his grandmother for seventy percent of his childhood. She was his source of "real love". But when his father went to prison, and then his grandmother passed away, his biological buffer was gone. He was left completely exposed to early life stress.

Professor A.

And we see the physiological toll of that exposure. At just twenty-six, Kentrell revealed to Funny Marco that during his last tour, a doctor told him the left side of his heart was swollen—it was medically enlarged. He pushed through every show anyway. And he says this incredibly poetic, heartbreaking line: "My heart kind of still is enlarged on this little side. That explains the music though, right? She’s hurting.".

Marcus

Oh, man... "She’s hurting." That is the literal physical embodiment of trauma. The body keeps the charge. Chronic HPA-axis activation and systemic inflammation don't just damage the brain; they damage the cardiovascular system. His enlarged heart is the biological receipt of the trauma he survived.

Professor A.

And look at how he describes his different personae. He tells Marco that "Top" and "Young Boy" are different from "Control"—who is his real, relaxed self. He says "Top" is the "crash-out" character. And listen to his exact words: "It used to be a movie role that I took on and couldn't put down, and I never went to go get treatment to break out of it. So I just always be crazy.".

Marcus

That is a textbook description of a traumatic adaptation. He built the "Top" persona as a violent, hyper-vigilant defense mechanism to protect himself in Baton Rouge—a survival character. But because of a total lack of trauma-informed intervention or treatment, the survival character became a cage. He couldn't put the mask down.

Professor A.

And the psychological consequence of that is devastating. He admits to Marco that he used to tell his wife he wouldn't live to see twenty-one. Then, when he was in jail, he told her he wouldn't live to see twenty-five. He talks about how, during his last federal prison stint, he was completely stripped of his possessions, he cried, and he was completely broken. This is a young man who has lived his entire life under the shadow of developmental myopic threat-monitoring, expecting death at any moment.

Marcus

And this is where we have to connect Kentrell's story—and Joseph Appiah's story in Gonzales—to the law. We read Professor Jenny Carroll’s 2016 article, Brain Science and the Theory of Juvenile Mens Rea. Carroll points out a massive, hypocritical gap in how our legal system uses neuroscience.

Professor A.

She does, Marcus. The Supreme Court has happily used brain science to adjust punishment—categorically banning the death penalty in Roper v. Simmons, banning life without parole for non-homicides in Graham, and banning mandatory life without parole in Miller. They even adjusted the Fourth Amendment standard of custody in J.D.B. v. North Carolina, saying a child's age matters when determining if they felt free to leave an interrogation.

Marcus

Right! They admit kids' brains are underdeveloped when it comes to sentencing and custody. But when it comes to substantive guilt—the element of mens rea, the actual intent to commit the crime—the law completely shuts the door on science. They apply a "one-size-fits-all," adult-referential standard of intent to seventeen-year-old kids.

Professor A.

And that is a fundamental logical and moral failure. As Carroll argues, mens rea is supposed to measure actual, individual culpability. But if a child's prefrontal-amygdala connectivity is underdeveloped, they do not perceive risk, process cause-and-effect, or regulate impulses the way an adult does. To judge their "intent" using an adult baseline doesn't measure their actual state of mind. It reduces mens rea to a fictional, objective standard that ignores the reality of the adolescent brain.

Marcus

Exactly. Under adult-centric law, a traumatized kid who "crashes out" because their hyper-reactive amygdala perceived a neutral face as a life-or-death threat is treated as having "premeditated, cold-blooded intent". The system completely manufactures "risk" by taking a child's traumatic survival adaptation and labeling it as "inherent criminal dangerousness".

Professor A.

And this brings us to the ultimate, critical turn of Week 2: Whose trauma gets treated, and whose trauma gets charged? If a wealthy, white teenager in an affluent suburb exhibits sleep problems, hyper-vigilance, and outbursts of aggression, their parents take them to a clinical psychologist. They get a clinical referral. They get neurofeedback, therapy, and "environmental predictability". They are seen as a "child who has survived trauma".

Marcus

But if a low-income Black or brown teenager in Baton Rouge or Ascension Parish exhibits the exact same neurodevelopmental profile of trauma, they don't get a clinical referral. They get a school suspension, a police record, and eventually, a first-degree murder charge. The difference isn't in their brains, Professor A. The biology of trauma is identical. The difference is in how the state decides to respond to that biology. One child is given a path to healing; the other is locked in a cage that consolidates the trauma.

Professor A.

And that is why we must fight for a deeply embedded, system-wide, Trauma-Informed Care approach. We have to screen for ACEs early. We have to provide environmental stability and biological buffers. We have to realize that when we punish delinquency without addressing the trauma that manufactured it, we are simply punishing the physical scars of childhood abuse.

Marcus

Man... "The body keeps the charge.". If we don't discharge that trauma through healing, the legal system will just keep charging these kids with crimes.

Professor A.

A powerful note to end on, Marcus. Thank you. And to our listeners: don't forget that your Field Note is due this Sunday and Zoom Check-In is this Thursday, August 27, at 6 PM Central. I look forward to seeing you there. Until next time, keep asking the right question: not "What is wrong with you?", but "What happened to you?"
