Trauma- and Stressor-Related Disorders

The case: Theo, 9

Case: Theo, 9. Five chapters follow: the case, epidemiology, presentation, functional neuroscience, and treatment.

The case: Theo, 9

Theo is nine and in fourth grade. He builds brick models from memorized instructions, plays goalkeeper on Saturdays, and has had the same best friend since kindergarten. In May, five months before this evaluation, a kitchen fire started in his family's house at about two in the morning. The smoke alarm woke his parents. His father carried his six-year-old brother, Milo, out the front door; his mother led Theo down the hallway through smoke to the yard. Theo and his mother were assessed in the emergency department and discharged. The fire department report documents an electrical fault; the kitchen and hallway were destroyed. The family lived with Theo's grandmother for ten weeks, then moved to a two-bedroom apartment across town in August. Theo now shares a room with Milo. He missed the last three weeks of third grade.

Presenting concern

The pediatrician's referral reads: "Irritability and sleep disturbance since house fire in May. School reports frequent outbursts. Query PTSD. Parents request evaluation." His fourth-grade teacher, Ms. Alvarez, who met him in August and was told about the fire, keeps a log of "trauma reactions" listing eleven incidents in six weeks.

Theo says: "I'm not scared of fire. I hate the alarm. And Milo touches my stuff. And math is stupid this year." Asked about the night, he looks at the floor and says, "Can we not."

Developmental and family history

Milestones on time. His parents describe him as "intense" from toddlerhood: big reactions, quick to settle. No prior mental health contact, medical problems, or medications. Before the fire he slept in his own room, read for twenty minutes, and fell asleep easily. A maternal aunt has panic disorder. Screening for other adversities is negative. The family is not in ongoing danger.

Since the fire

Theo has nightmares two or three nights a week. Some are about fire; more often he is in a large building and cannot find his mother. He wakes, goes to his parents' room, and settles within minutes when his mother sits with him. He checks the green light on the smoke alarm before bed. He will not enter the kitchen while the stove is on and will not ride past the old house. At his grandmother's, when a neighbor's barbecue smoke drifted in, he stood on the front step until it cleared. He startles at loud sounds. He still builds and plays soccer.

At school

During the September fire drill Theo froze in his seat, then cried, and could not settle for the rest of the day. Two weeks later a four-second alarm test sounded; he left the classroom and walked to the office. The other nine logged incidents occurred during or just after math. Fourth grade introduced long division; Theo shoves the worksheet off the desk, says "this is stupid," and puts his head down. When the aide sits with him he resumes within ten minutes. Mr. Bennett, his third-grade teacher, says drills before the fire were "loud, then he lined up like everyone else," and that multi-step math "was always where he'd get stuck and say it was stupid; a step card helped."

At home

Milo goes to bed at 7:30. Theo, told to stop building and get into a dark room, argues, comes out repeatedly, and shouts that he "can't sleep with Milo in there." His mother, Dana, moves Milo to the parents' bed "to keep the peace," and Theo settles and builds for another half hour. She says, "I can't be the one to make him more upset." His father, Andre, says, "He's nine. He needs to share a room like anyone else. Dana says he's traumatized." Dana has slept poorly since May, checks the stove repeatedly each evening, and becomes tearful describing the hallway.

In session

Theo builds from a box of bricks while talking. His hands stop when the fire is mentioned. A siren passes outside; he glances at the window, his leg jiggles, and he continues describing his gloves. Asked about long division he becomes animated and irritated: "She goes too fast and then it's a test." Before leaving he asks whether the clinic has smoke alarms.

Epidemiology

How common

The NCS-A found a lifetime prevalence of posttraumatic stress disorder of 5.0% among US adolescents aged 13 to 18 by structured interview [53]. A dedicated analysis of the same survey, restricted to ages 13 to 17 and using DSM-IV criteria, gives the figures behind it: 61.8% of adolescents had been exposed to at least one potentially traumatic event, 4.7% met lifetime criteria for PTSD (7.3% of girls and 2.2% of boys), and the conditional risk of PTSD after exposure was greatest following interpersonal violence [300]. Those are high-income-country adolescent figures. Theo is nine, and no source in the list gives a rate for school-age children; the exposure figure says that most adolescents have been exposed to something and few have the disorder, and the conditional-risk finding says that what the event was matters to the risk.

Exposure in a high-exposure population

What the list does supply is a study of children at the extreme of exposure. Among 84 Central American and Mexican children aged 1 to 17 assessed by parent interview after release from US immigration detention, 97.4% had experienced at least one traumatic event before migration, and the severity of PTSD symptoms was most strongly predicted by premigration trauma and by the duration of separation from a parent [5]. The study gives no prevalence of the disorder in the abstract, and its population has little in common with a child who lived through a house fire in an intact family. It is cited here for two structural points that transfer: trauma before the index event predicts symptom severity, and separation from a caregiver is itself a predictor of symptom severity.

What a childhood diagnosis predicts

In the Dunedin cohort, three quarters of adults with a disorder at 26 had received a diagnosis before 18, often of a different disorder, and adult anxiety disorders in particular were preceded by a broad array of juvenile diagnoses [59]. The cohort's abstract does not report PTSD separately. For Theo the relevance is general: adult disorder commonly has a childhood history, although the follow-back design does not say how often a childhood presentation like his is followed by one, and the treatment chapter's attention to what the fire does not explain is part of what that continuity recommends.

Protective factors, from an adult sample

A latent profile analysis of 791 Italian Red Cross emergency responders, mean age 39.9, identified an adaptively resilient profile (n=408) and a maladaptively vulnerable one (n=343), the latter marked by higher self-judgment, isolation and over-identification [4]. It is an adult occupational sample with no child data and is cited only to show that the components of self-compassion have been treated as measurable protective and risk factors in exposed adults; nothing in it bears on a nine-year-old.

Treatment as a source of epidemiological knowledge

The trauma-focused cognitive behavioral therapy review in the list [6] is the module's treatment source; no abstract was available through the routes used, so no figures are drawn from it. It is cited in the treatment chapter.

What this case cannot establish

Theo's exposure is documented, and the base rate for the disorder among adolescents is 1 in 20 over a lifetime. Neither figure says whether his nightmares and startle will meet criteria at the one-month duration threshold [269, 111], nor which of his three problems the fire explains; the presentation chapter separates them without help from the numbers, because the numbers here cannot help.

Source status

#53 from the article text; #300 added from the citation check of 2026-10-05 (abstract inspected); #5 from the Crossref abstract; #59 from the abstract; #4 from open-access full text; #6 bibliographic record only; #269 and #111 added from the tracker for the duration criterion. A school-age prevalence source is still absent.

Figures for this chapter

Figure TRA.E1. What the list can and cannot say about PTSD in children. Top, the chain a clinician would want quantified for Theo: how often school-age children are exposed to a traumatic event, and how often exposed children develop PTSD; the reference list now supplies both links for adolescents aged 13 to 17 (61.8% exposed to at least one potentially traumatic event; conditional risk of PTSD highest after interpersonal violence) [300], and still no school-age figure, so the links stay dashed. Theo, 9, exposed in a house fire and under assessment, sits at the exposed node. Bottom, the two figures the list does supply, each linked by a dotted line to the quantity it only resembles: a lifetime PTSD prevalence of 5.0% among US adolescents aged 13 to 18 [53], which counts exposed and unexposed adolescents at older ages, and 97.4% premigration trauma exposure among 84 children aged 1 to 17 assessed after release from US immigration detention, a high-exposure sample whose abstract gives no PTSD prevalence [5]. The figure illustrates the limits of the cited populations; it does not estimate exposure or PTSD risk in nine-year-old children. Data from [53], [5].

Presentation

Perception, interpretation, participation

Theo's referral arrives with a diagnosis already attached. The pediatrician queries PTSD, the teacher logs "trauma reactions," and his mother explains bedtime by saying he is traumatized. The task is to look at what Theo perceives, how he interprets it, and what he does, before deciding which observations the fire accounts for.

When the siren passes the clinic window, Theo hears it, looks toward it, and his leg moves. He then continues describing his gloves. Perception and a brief physiological response are observable; the interpretation "danger" was either not made or was made and set aside; participation continued. During the September drill the same sequence went differently. He perceived the alarm, stopped moving, cried, and could not rejoin the class for the afternoon. The difference between the two events lies in what the sound predicted for him, how strongly, and what remained available to him afterward.

When he says "Can we not," he is telling the clinician that the topic produces something he prefers to avoid. That is an observation about avoidance and about his capacity to say so, not evidence that he cannot talk about the fire. He chooses not to, in this setting, on this day.

The pattern the exposure explains

Five months after a fire he walked through, Theo shows a recognizable pattern. He has nightmares. He responds to cues that resemble the event, the alarm and the smell of smoke, with fear and withdrawal his third-grade teacher never saw. He avoids the kitchen with the stove on, the old street, and conversation about the night. He checks the smoke alarm before bed, startles, and sleeps poorly. These features have persisted well beyond the first weeks and impair him at school and at home.

Grouped by current diagnostic convention, they fall into intrusion, avoidance, negative changes in cognition and mood, and altered arousal and reactivity, with a required duration beyond one month [269, 111]. Criteria for children six and younger are written differently, with more weight on observed behavior and fewer required symptoms [269, 111]. Theo, at nine, is assessed against the general criteria, which depend heavily on what he can report. In the National Comorbidity Survey Replication Adolescent Supplement, lifetime prevalence of PTSD among US adolescents aged 13 to 18 was 5.0% [53]. That figure describes older children over a lifetime window; it does not apply to Theo's age group and says nothing about how often a single house fire produces this pattern.

Each cluster deserves a description rather than a checkmark. The nightmares are intrusions, but their content is usually not fire; it is being unable to find his mother. The drill response is a cue-triggered reaction that outlasted the cue by hours. The kitchen avoidance is specific to the stove being on, which tells us what the cue is. His statement that he is not scared of fire but hates the alarm should be taken literally: the alarm, not flame, is what he perceived first that night. Checking the green light is vigilance directed at a safety signal rather than at a threat.

What the exposure does not explain

Nine of the eleven logged incidents occurred during or just after math. Fourth grade introduced long division in September. Mr. Bennett's account establishes that multi-step problems produced the same words, "this is stupid," and the same shutdown before the fire, and that a step card worked. The behavior has a history that predates the exposure, a setting with no alarms or smoke in it, and a rate of recovery, about ten minutes with an aide, that is faster than after the drill.

This does not make the fire irrelevant to math. Theo missed three weeks of instruction. He sleeps poorly, and afternoon math follows a morning that began tired. A trauma history can weaken a capacity by removing the opportunity to build it, and a trauma response can reduce access to a capacity that is intact. Both may be operating. Neither turns a long-division outburst into a trauma reaction. The frustration is real, current, and about division.

Bedtime has the same structure. Theo does not want to stop building and lie in a dark room at 7:30 beside a six-year-old, having had his own room and a reading routine until May. His protest is a nine-year-old's protest at a real loss. When Milo is moved, Theo settles and keeps building, which is what a child does when a frustration is removed, not what a child does when fear is removed. Fear is visible at night in the other observation: the nightmare, the walk to the parents' room, the settling when his mother sits with him.

Two pairs of observations that look alike

The drill and the worksheet are both "he melted down in class." The nightmare and the bedtime protest are both "he doesn't sleep." In each pair, the first member is a response to a cue that has acquired the meaning of danger, followed by slow recovery and comfort seeking. The second is a response to a present demand he finds aversive, followed by fast recovery once the demand changes. The teacher's log and the parents' account merge them. Separating them requires asking, for each incident, what preceded it, what he did, how long it lasted, and what ended it.

Acute stress, adjustment disorder, and PTSD on one timeline

Had Theo been seen two weeks after the fire, clinging, sleepless, and startled at his grandmother's, the pattern would have fallen within the window for acute stress disorder. That diagnosis requires a minimum number of symptoms lasting from three days to one month after exposure [270, 111]. In many children, symptoms decline substantially without treatment over the following months, and PTSD prevalence roughly halves between one and six months after trauma [271], which is why the label carries a different expectation. Had his difficulties consisted of sadness and irritability about the move, the shared room, and the new class, without cue-triggered fear or intrusions, adjustment disorder would describe a response to the consequences of the event rather than to the event itself [111]. Theo has both: a persisting cue-driven pattern the fire explains, and ordinary distress about what the fire cost him, which the fire caused but does not explain in the same way.

Populations differ on this timeline. Children held in immigration detention at the US southern border, studied by Sidamon-Eristoff and colleagues, carry exposure that is often cumulative and ongoing rather than a single past night [5]. Theo's single-incident exposure in a safe, intact family is a favorable situation, not a typical one.

The presumed total cause

Once trauma is correctly invoked, it can become the explanation for everything that follows. Ms. Alvarez, who never met the pre-fire Theo, has no other frame. Dana, who is herself frightened and sleeping badly, cannot risk being the person who upsets him. The label is doing work in both settings, and the work is the same: it removes the demand. In math the worksheet is removed; at bedtime the brother is removed. The behavior that removes the demand is being learned, and it is being learned in exactly the settings where the demand is ordinary.

The error runs in the other direction too. Treating the drill freeze as defiance, or the nightmare walk as attention seeking, would be equally wrong. The correction is not to decide whether Theo "has trauma" but to describe each episode in terms that apply to any child: what cue, what response, what recovery, what consequence. In that language, a benign fire drill acting as a conditioned cue and a hard worksheet acting as a frustration can both be stated precisely, and the difference between them stays visible.

What this case cannot establish

The presentation cannot establish that Theo's math difficulty is unaffected by the fire; missed instruction and poor sleep are plausible contributors of unknown size. It cannot establish whether the nightmare content reflects the attachment threat of that night or ordinary nine-year-old dream material given new salience. It cannot establish how much of Dana's response reflects her own post-fire state. It cannot establish whether the pattern met full criteria at three months, since no one examined him then. And one siren in one clinic visit cannot establish how Theo responds to alarms in general, only how he responded to that sound, in that room, with his mother present.

Figures for this chapter

The case chronology from the May fire to the October evaluation: above the axis, what happened (fire and emergency visit, three missed weeks of third grade, ten weeks at his grandmother's, the August move into a shared room, the start of fourth grade, the September drill, the alarm test, the referral); below, three observation tracks shaded where active, cue-triggered responses the fire explains, sleep as a State that limits access, and the math and bedtime frustrations that are present demands, with the math difficulty shown reaching back before May; then the acute stress window, the one-month PTSD duration threshold, and a rail of what each observer called it. Exact dates within a month (the barbecue smoke, the move, the first day of school) are not given in the case and are placed approximately, with the dotted tick marking the least certain.

Figure TRA.2. Same log entry, different episode. The September drill and the long-division worksheet, both logged as "trauma reaction," compared row by row (antecedent, response, recovery, what ended it, and the functional reading): a conditioned cue with a defensive response, slow recovery, and comfort, against a present demand with protest, fast recovery, and the demand removed, a pattern Mr. Bennett's account shows predates the fire. The figure separates the two episodes; it does not show that the fire is irrelevant to math, since missed instruction and poor sleep may contribute, and the nightmare and the bedtime protest divide the same way without being drawn.

Functional neuroscience

Part 1. Functional layer

The alarm as a conditioned cue

Before May, a fire alarm was represented, for Theo, as a loud interruption followed by lining up. It is now the first moment of the worst night of his life. Threat representation is what the child holds about which events predict harm, how imminent that harm is, and what can be done about it. Its content is learned, and one exposure can be enough to write it.

The alarm did not become threatening because Theo decided it was. Pavlovian threat conditioning is a Process in which a previously neutral cue, paired with an aversive event, comes to produce defensive responses on its own [174, 176]. The response occurs before any deliberate interpretation. This is why "I'm not scared of fire, I hate the alarm" is an accurate report. His fear is attached to the cue that preceded the danger, not to the danger as a concept.

An objectively benign stressor, a scheduled drill in a building that is not on fire, can therefore act as a conditioned cue. This is what "trauma response" means when used carefully, and it places Theo's drill response in a common vocabulary rather than a special category. The response is a defensive behavior from an ordinary repertoire, freezing and crying, triggered by a learned cue, with a slow rate of affective recovery. Every element of that description applies to fears that have nothing to do with trauma.

The representation has also spread. Threat generalization is the process by which a learned response extends from the trained cue to cues that resemble it [174, 176]. Theo's response to barbecue smoke, his kitchen avoidance when the stove is on, and his question about the clinic's alarms show the boundary of the represented threat moving outward from the alarm to smoke, to cooking, to buildings. Generalization is not a malfunction; it protects against a cue that may not recur in the same form, at the cost of ordinary settings acquiring danger.

Safety learning is new learning, not erasure

Fear extinction is the process by which repeated exposure to the cue without the aversive event produces a new association that competes with the old one [171, 176]. In this account the original association is not deleted; it remains available and can return when context changes, time passes, or a related aversive event occurs [171]. This is why a child who tolerates the alarm in a therapist's office can still freeze in the school hallway. What was learned is "this cue is safe here, now," and the "here, now" is part of the learning.

Safety learning describes a related but distinct achievement: representing a cue or context as one in which harm does not occur, so that defensive responding is actively inhibited rather than simply absent [272]. Checking the green light is Theo's attempt to establish safety before sleep: a reasonable strategy, and a sign that safety is not yet the default condition of his bedroom. His task is not to stop noticing alarms but to learn that in this building, on this day, the alarm predicts lining up.

Hyperarousal as a state that changes access

Hyperarousal after trauma is a State: a condition that changes access to capacities without changing the capacities themselves. It includes increased physiological readiness, threat-biased attentional selection, in which processing is preferentially allocated to threat-relevant input, and a lowered startle threshold. Sleep loss adds to it and is partly produced by it.

The consequences for Theo's afternoon are direct. Multi-step math draws on working-memory maintenance and on persistence under difficulty, the capacity to continue with a task after an error. Theo's third-grade record shows both capacities present under good conditions and limited: he needed a step card. After a night broken by a nightmare, with attention partly allocated to the sounds in the hallway, the same capacities are less available. This is state-dependent loss of access. The fire did not cause the math difficulty, which is older than the fire; its aftermath has made an existing limit easier to reach. A step card supplies the sequence he cannot maintain; better sleep restores access to what he could already do. Neither is a treatment for trauma.

Intrusive memory as reactivation

Involuntary memory reactivation is the process by which a cue triggers a stored representation without deliberate search [273]. Theo's nightmares and his hours of distress after the drill are examples. One account distinguishes a sensory, cue-bound form of trauma memory from a contextualized narrative form that can be deliberately retrieved and placed in time [274, 273]. On that account the drill did not remind Theo of the fire; it re-presented the alarm, and the alarm brought the hallway with it.

A nine-year-old's narrative of the event is incomplete for developmental reasons. Theo was asleep when it began, was moved through it by an adult, and has been told the story more often than he has told it. His reluctance to talk is avoidance, but what he could say may be fragmentary, and fragments are what intrusions are made of. The nightmare in which he cannot find his mother is not a replay but a reactivation of the night's central threat, which for a child of nine was separation.

Regulation, co-regulation, and attachment representations

Emotion regulation runs through several routes: moving attention, changing meaning, changing the situation, and using another person. Reappraisal is available to a nine-year-old in conversation and much less at the peak of arousal. Co-regulation, in which a caregiver's presence and behavior change the child's state, is therefore a major route for Theo, and it is visible: he settles within minutes when Dana sits with him after a nightmare.

That observation also shows an intact attachment representation. He holds a model of his mother as available and effective, and uses it. His proximity seeking after a nightmare is a capacity working as designed, not a symptom. The nightmare content suggests the representation was tested that night, and the walk to his parents' room is how he re-tests it. Treating that walk as a sleep problem to be extinguished would remove a working regulatory route.

Co-regulation depends on the regulator. Dana checks the stove, sleeps poorly, and cannot describe the hallway without crying. A caregiver in a persisting threat state sends a different signal than before the fire, and a child of nine reads it. Whether her state impedes Theo's recovery cannot be established here, but it is part of the environment his regulation runs in.

An ordinary frustration in the same vocabulary

The long-division outburst and the bedtime protest use the same functional terms with different values. The antecedent is a demand, not a cue that predicts harm. The response is protest from an ordinary repertoire. The rate of recovery is fast once the demand changes. And the consequence of the response has been changing the demand: the worksheet goes, the brother goes. Instrumental learning is the process by which a behavior increases when it produces a valued outcome [176]. The shouting at bedtime is reactive in origin, a real frustration at a real loss, and is becoming instrumental in maintenance, because it reliably produces the room to himself. That is neither manipulation nor trauma; it is a child learning what works.

Functional variables keep the two accounts separate without denying their overlap. The fire made bedtime dark and shared and afternoons tired. But the operative variable in each outburst is the present demand and its consequence, and that is where change is possible.

Development changes each of these

At nine, Theo depends on adults for appraisal; whether the apartment is safe is a question he answers partly by watching his mother. His threat representation is less verbal and less open to reasoning than an adolescent's. He cannot avoid the school alarm, which makes school both the hardest setting and the one where safety learning can occur most often. Developmental work in rodents and humans has suggested that extinction learning is relatively attenuated in adolescence compared with childhood and adulthood [177]. That is a group finding from a laboratory task; it does not predict that Theo, at nine, will respond better to treatment because of his age.

Part 2. Circuits, development, and genes

A threat-learning circuit

Rodent work identifies the amygdala as necessary for acquiring and expressing conditioned defensive responses, with the hippocampus contributing contextual information and the medial prefrontal cortex contributing to extinction and its retention [174, 176]. Human imaging in adults has related amygdala and ventromedial prefrontal activity to conditioning and extinction tasks [174]. The findings do not establish that Theo's amygdala is overactive; nothing in this case measures it. What they support is the plausibility of the functional account: a cue can acquire threat value through learning, and safety is learned separately and context-dependently.

Developmental change and caregiver buffering

Developmental imaging describes changing coupling between amygdala and medial prefrontal cortex across childhood and adolescence [178], and one study reports that maternal cues reduce amygdala reactivity in children but not in adolescents [275]. If those findings generalize, they offer a circuit-level correlate for what is observable at Theo's bedside. His settling when his mother sits with him is established by observation; the mechanism is inferred from group data in other children performing other tasks.

Sleep and memory

Sleep participates in the consolidation of emotional memory and in the retention of extinction learning [276, 277]. A child who sleeps badly after a drill may retain less of whatever safety learning the day contained. Trauma-related nightmares can occur in both rapid eye movement and non-rapid eye movement sleep, and disrupted processing of emotional memory during sleep is one proposed explanation for their recurrence [278]. For Theo the usable claim is narrow: sleep is part of the State that limits access, and improving it is a target in its own right.

Genetic liability

Twin studies indicate that liability to PTSD after exposure is partly heritable; candidate gene associations have replicated inconsistently across studies, and large genome-wide studies now give stronger evidence for common variants of small effect [279, 280, 281]. None of this identifies why Theo, rather than Milo, developed a persisting pattern. The difference in their exposures, one carried out asleep and one walked through smoke, is a more proximate explanation than any genotype. A predisposition cannot specify the content of a nightmare.

Moving between levels

A rodent conditioning experiment tests a specified operation under controlled conditions; a developmental imaging study describes group differences in a task. Connecting any of these to Theo's freeze in a school hallway requires an inference none of them makes. The functional description, naming cue, response, recovery, and state, is what the observations support directly.

What this case cannot establish

This chapter cannot establish that Theo's drill response is mediated by the circuit described in rodents, only that the pattern is consistent with the kind of learning that circuit implements. It cannot establish whether his generalization to smoke and kitchens will narrow with extinction. It cannot apportion his math difficulty among sleep loss, missed instruction, and pre-existing limits. It cannot establish that Dana's state affects his recovery, only that co-regulation depends on it. And it cannot establish that the bedtime shouting is now fully instrumental; only changing the consequence will show how much reactive frustration and learned consequence each contribute.

Figures for this chapter

Figure TRA.3. Cue, threat, safety: two competing associations. The alarm sound sits between a threat representation learned in May in a single exposure (the alarm predicts smoke, the dark hallway, and separation, generalizing outward to barbecue smoke, the stove being on, and an unfamiliar building) and a safety representation being learned now and bound to context (the alarm predicts lining up), with checking the green light before bed shown as vigilance at a safety signal. Which association controls behavior depends on context, time since learning, and current state, which is why tolerating the alarm in a therapist's office does not settle the school hallway. The figure draws the functional account only; no circuit is shown, and nothing in the case measures one.

Figure TRA.4. Capacity, state, and access. Two routes to the same afternoon: on the left, an intact but limited capacity for multi-step math (present in third grade with a step card) has its access narrowed by a State of sleep loss and threat-biased attention, drawn as a wedge, leaving less available in afternoon math; on the right, the capacity to tolerate the alarm is itself reduced by the threat representation learned in May, the same State narrows it further, and what remains at the drill is small. Bar lengths are schematic, not measurements. The step card and better sleep act on the left and are not trauma treatment, safety learning at school acts on the right, and the figure cannot apportion the math difficulty among sleep loss, missed instruction, and the pre-existing limit.

Treatment

Goals in Theo's terms

Theo wants the alarm to stop mattering, his own space, and math to slow down. His parents want him to sleep, and Dana wants to stop being afraid of upsetting him. These translate into three targets the earlier chapters kept apart: conditioned responses and intrusions the fire explains; a state of poor sleep and hyperarousal that limits access to what he can do; and two ordinary frustrations, long division and a shared room, producing behavior now and reinforced by the responses they get. Each has its own plan and its own measure of progress.

Trauma-focused CBT: components and evidence

Trauma-focused cognitive behavioral therapy (TF-CBT) has the most extensive trial support among treatments for childhood PTSD and is delivered with a caregiver as an active participant [6]. Its components include psychoeducation and parenting skills, relaxation, affect modulation, cognitive coping, a trauma narrative with processing, in vivo mastery of trauma reminders, conjoint child-caregiver sessions, and enhancing safety [6]. The order is graded: skills precede the narrative, and the narrative precedes in vivo work.

The evidence concerns outcomes. Randomized trials show reductions in PTSD symptoms, depressive symptoms, and behavior problems relative to comparison conditions across trauma types and ages [6]. That is the basis for recommending it to Theo; it does not demonstrate that the treatment works through the mechanisms in the functional chapter. The trauma narrative is designed on the idea that a fragmentary, cue-bound memory can be organized into one that can be deliberately retrieved and placed in the past; in vivo mastery is designed on an extinction model. Whether those designs name the active ingredients is a separate question. Mediation evidence is limited but not absent: a review of trauma-focused psychotherapy in youth found moderate evidence that post-traumatic cognitions mediate outcome, amid substantial methodological gaps [282].

For Theo the parenting component is not an add-on. Dana participates in his nightmare recovery and his bedtime protest, and she is frightened. TF-CBT's caregiver sessions address the caregiver's own reactions and how the child's behavior is managed at home [6]. Whether Dana needs treatment in her own right is a question for her own assessment, raised with her directly.

In vivo mastery and the school alarm

The alarm is the cue Theo cannot avoid, and school is where it sounds. In vivo mastery in TF-CBT is planned exposure to reminders that are objectively safe but avoided [6]. For Theo this means a graded sequence: the alarm sound at low volume in session, the school's own tone from a recording, standing in the hallway where the drill happened, and eventually a drill he knows is coming. Each step uses skills already learned, with an adult who can co-regulate, and is repeated until his response recovers within the session.

The functional chapter supplies two features the trial evidence does not specify. Extinction is context-bound, so the sequence has to reach the school itself. And extinction competes with the original learning rather than replacing it, so a return of the response after a new stressor or a real emergency is expected, not a treatment failure. The school is told this in advance, and Ms. Alvarez is asked to warn Theo of scheduled drills during treatment and to log alarm episodes separately from math episodes.

The state: sleep, nightmares, and the bedtime that is not a trauma problem

Theo's sleep problem has two parts with two plans. Nightmare waking is addressed through the trauma work and through what already works: his mother's presence. It is not extinguished; Theo is not sent back to his room alone. Imagery rehearsal, in which the child rehearses a changed ending to a recurrent nightmare while awake, is supported by a randomized trial in adults with PTSD [283]. A small trial in children studied frequent nightmares without PTSD [284], so its use for Theo's posttraumatic nightmares is an extrapolation. It can be added once narrative work has begun.

The bedtime protest is addressed as a bedtime protest. The loss of Theo's room is real. The plan gives what can be given: a reading light and twenty minutes of reading in bed, as before the fire; a shelf Milo cannot reach and a lidded box for the current model; a bedtime half an hour after Milo's, spent reading in the shared room while Milo falls asleep. What is not given is the room to himself in response to shouting. Dana and Andre agree on this together, because their disagreement is part of what Theo responds to. The parents are told that protest may increase before it declines, because the behavior has been working; such a burst is possible, not inevitable [208].

The two parts are kept apart on purpose. If Theo wakes from a nightmare, the response is comfort. If he refuses to get into bed, the response is the plan. Parents tell the difference by what preceded the behavior and what ends it; the presentation chapter's paired observations are the teaching tool.

Long division as long division

The math plan is the third-grade plan with one addition. The step card returns. Ms. Alvarez is asked to seat Theo where the aide can reach him before the worksheet is on the floor, and to reduce the number of problems rather than the requirement to do them. The addition is timing: afternoon math after a bad night is a poor test of what Theo can do, so the teacher notes the previous night's sleep against each math episode, letting state and capacity be told apart over the term.

None of this is trauma treatment, and that is the point. Treating a frustration as a frustration gives Theo a solution to the problem he has and stops teaching him that the way out of division is an outburst. It also protects the trauma work from being asked to fix what it cannot. If math episodes persist after sleep improves and the step card is back, that is information about a learning need, not a sign that the trauma was deeper than thought.

Medication

No medication has established efficacy for PTSD in children. Randomized trials of sertraline in pediatric PTSD, alone or added to TF-CBT, did not show benefit over placebo on primary outcomes [285, 286]. Prazosin, used for trauma-related nightmares in adults with mixed trial results, has only retrospective chart-review evidence in children [287, 288, 289]. Alpha-2 agonists have been used for hyperarousal on pharmacological rationale; a 2024 systematic review found no randomized, double-blind, placebo-controlled trials of them in pediatric PTSD [290]. Evidence in children with chronic insomnia suggests that melatonin shortens sleep-onset latency [291]. For posttraumatic sleep disturbance, the protocol for a placebo-controlled pediatric trial was published in 2025 [292], but no efficacy results had been identified as of October 2026.

The functional account makes the pharmacological rationale intelligible: a drug that reduces noradrenergic arousal might change the State that limits access. That is a reason to study such drugs, not to prescribe one, and the existing trials do not support the step. Medication is not part of Theo's initial plan. It would be reconsidered if a comorbid condition with its own evidence base emerged, or if sleep failed to improve and the family wished to weigh an option of uncertain benefit.

What would have been different at two weeks, or with a different pattern

Seen in the acute stress window, the plan would have been support, information, restoration of routine, and attention to the parents' state. Single-session psychological debriefing is not recommended, and for subthreshold symptoms in the first month, active monitoring with follow-up within one month is advised [293, 294]. Had Theo shown only sadness and protest about the move and the room, without conditioned responses and intrusions, the adjustment disorder label would have pointed to problem-solving, family work on the room, and time, without a trauma narrative. The plan follows the formulation; Theo needs both because he has both.

Why the distinction matters over time

In a prospective birth cohort followed into adulthood, most adults with a mental disorder had met criteria for a diagnosis before age eighteen, not always the same disorder as the adult one [59]. Childhood patterns continue and transform. A nine-year-old who learns that outbursts remove demands, or who is taught that he is fragile, carries that learning forward as surely as he carries a conditioned cue. Getting the formulation right now, and keeping the fire's explanatory role at its true size, protects both trajectories.

Protective factors are often invoked, and that literature should be read at the level it was collected. A study of self-compassion components among adult emergency responders [4] is an adult sample under repeated occupational exposure and does not say what protects a nine-year-old after one fire. What is observable in Theo is concrete: an intact attachment, preserved interests, a friend, a safe home, and a father asking the right question about the room.

What this case cannot establish

The plan cannot establish that TF-CBT will work for Theo; trials estimate group outcomes. It cannot establish that exposure to the alarm will generalize to an unannounced test, or that the bedtime protest will decline once the consequence changes; it tests those predictions. It cannot establish whether Dana needs her own treatment. And it cannot say in advance how much of the math difficulty will resolve with sleep and how much reflects a learning need; that is what the separated log is for.

Figures for this chapter

Figure TRA.5. Three targets, three plans. A logged episode is sorted by what preceded it, read with what Theo did, how long it lasted, and what ended it: a cue resembling the fire leads to trauma work (TF-CBT with Dana participating, skills before narrative before in vivo mastery that reaches the school, comfort after nightmares), poor sleep the night before leads to the state plan (sleep routine, comfort after a nightmare, imagery rehearsal once narrative work has begun, sleep noted against each math episode), and a demand leads to the frustration plan (step card, fewer problems, a seat near the aide, reading light and reading time, a shelf and lidded box, a later bedtime, one consistent parental response). The bottom bar applies to every branch: if the behavior removes the demand, the consequence changes, and protest is expected to rise for several nights before it declines. The figure shows the sorting rule, not the sequence within TF-CBT.

Figure TRA.6. What the trial shows and what the model assumes. Left, the evidence: trauma-focused CBT, delivered with a caregiver as an active participant and made of the listed components, is linked by a solid arrow to reduced PTSD symptoms, depressive symptoms, and behavior problems at the group level in randomized trials [6]; right, the working model: the narrative organizing a cue-bound memory, in vivo mastery producing context-bound extinction, and caregiver sessions changing consequences and co-regulation, each linked to Theo's recovery by a dotted arrow labeled assumed, not measured. The trials support recommending the treatment; they do not show which component acts or through what, and a response in Theo would not confirm the mechanism. Data from [6] for the outcome panel.
