How to Heal From Post-Traumatic Stress Disorder (PTSD)

Summary

Dr. Victor Carrión, Vice-Chair of Psychiatry and Behavioral Sciences at Stanford, explores the neurobiological and psychological underpinnings of PTSD across childhood and adulthood. He explains how stress exists on a spectrum from beneficial to traumatic, how PTSD manifests differently in children versus adults, and details his evidence-based Cue-Centered Therapy (CCT) — a multimodal treatment approach that targets the specific triggers driving PTSD symptoms. The discussion emphasizes that PTSD is better understood as an injury to the autonomic nervous system than a permanent disorder, and that recovery is genuinely achievable.

Key Takeaways

• PTSD feeds on avoidance — ignoring trauma or assuming it will resolve on its own is the primary factor that allows it to worsen and become complicated by substance abuse or self-harm.
• Children are more vulnerable to PTSD than adults due to neuroplasticity — but that same plasticity makes recovery easier with proper intervention.
• PTSD in children is frequently misdiagnosed as ADHD; the key distinction is that hyperactivity in ADHD is persistent, while hyperarousal in PTSD is episodic and cue-triggered.
• PTSD symptoms are often driven by neutral sensory cues (a color, a sound, a smell) tied to trauma through classical conditioning — identifying even one or two cues can accelerate recovery.
• Elevated pre-bedtime cortisol is a measurable biomarker in children with PTSD, associated with reduced hippocampal volume and impaired memory function over time.
• Recovery involves building a personalized toolbox of coping strategies — tools the child develops themselves are more effective than those prescribed by a clinician.
• Cue-Centered Therapy reduces symptoms of PTSD, anxiety, and depression and produces measurable changes in prefrontal cortex activation.
• PTSD is increasingly understood as a post-traumatic stress injury — a dysregulation of the autonomic nervous system that can be rehabilitated.
• Practicing positive thoughts requires deliberate repetition because negative threat-responses are automatic while positive responses must be trained.
• The four-quadrant model (thoughts, emotions, physical sensations, actions) helps children and adults examine and interrupt maladaptive stress responses.

Detailed Notes

Stress as a Spectrum

• Stress operates on an inverted U-shaped curve: moderate stress improves performance, health, and happiness; beyond an optimal point, outcomes decline.
• Beneficial stress (e.g., vaccines, exam preparation) builds problem-solving skills and coping awareness.
• Traumatic stress occurs when stress threatens physical integrity — the body cannot restore homeostasis, and the system shifts into allostasis, meaning a physiological cost accumulates.
• PTSD typically results not from a single event but from an accumulation of stressors over time (the “backpack” metaphor).

PTSD in Children vs. Adults

• Children are more vulnerable to PTSD than adults — they cannot fight or flee, so they freeze and dissociate, which is an adaptive defense mechanism developmentally.
• Childhood PTSD does not always meet full DSM-5 diagnostic criteria yet still causes significant functional impairment (school, relationships, distress).
• Traumatic play in children is joyless, perseverative, and repetitive — an attempt to process events they lack tools to resolve.
• Children exposed to trauma often carry stressors that predate the identified trauma (e.g., poverty, domestic violence) that the “headline” event merely activates.

Transgenerational Trauma

• Genetic vulnerability (not confirmed epigenomic changes) can be passed across generations.
• Parents with unresolved PTSD may transmit symptoms through learned behaviors — avoidance, hypervigilance, emotional dysregulation — without any direct discussion of trauma.
• Both nature (genetics) and nurture (environment/learning) interact to shape vulnerability.

Cortisol and Brain Development

• Healthy cortisol rhythm: peaks in the morning, tapers through the day, with small bumps after meals or stressors.
• In children with PTSD symptoms: pre-bedtime cortisol remains elevated compared to healthy controls.
• Elevated nighttime cortisol is associated with nightmares, bedwetting, poor sleep quality, and fear responses at night.
• The hippocampus and prefrontal cortex have high concentrations of glucocorticoid receptors — making them vulnerable to cortisol-related damage.
• Longitudinal imaging showed a correlation between higher pre-bedtime cortisol and smaller hippocampal volume in affected children.
• Functional MRI showed children with PTSD symptoms activated fewer hippocampal voxels during memory tasks compared to healthy controls.
• The frontolimbic pathway (prefrontal cortex → amygdala) acts as a brake on hypervigilance — in PTSD, this brake is impaired.

PTSD vs. ADHD: A Critical Distinction

• Children are being over-medicated overall for mental health issues, while those with genuine ADHD are being under-identified and under-treated.
• Hyperactivity in ADHD is persistent across environments; hyperarousal in PTSD is episodic and cue-triggered.
• Inattentiveness in PTSD (dissociation) is often misread as the inattentive subtype of ADHD.
• Children with ADHD can hyperfocus on engaging tasks; this also occurs in PTSD, making the overlap clinically complex.
• ADHD and PTSD can co-occur; ADHD itself can be a risk factor for PTSD due to reduced environmental awareness.
• First-line treatment differs critically: ADHD → stimulant medication; PTSD → psychosocial intervention. Giving stimulants to a child with PTSD and no ADHD worsens hyperarousal.

Cue-Triggered Responses and Classical Conditioning

• PTSD cues are typically neutral sensory stimuli (a color, rain, a voice timbre) associated with the original trauma — not inherently threatening objects.
• Through classical conditioning, the body learns to respond to the cue as if the trauma is occurring again, regardless of current context.
• Identifying cues reduces shame (“I’m not bad or crazy”), builds self-understanding, and creates opportunities for intervention.
• Hypervigilance is not inherently bad — it can be protective in dangerous environments. The goal is developing the cognitive flexibility to turn it on and off appropriately.

Cue-Centered Therapy (CCT)

Developed by Dr. Carrión for children who may not have a parent available in treatment, and for those whose parent is the source of trauma.

Core components:

• Education: Teaching children about trauma, cues, classical conditioning, and the possibility of recovery.
• Toolbox development: Children identify and build their own personalized coping tools (empowerment over prescription).
• Narrative work: Covering negative, neutral, and positive life events — identifying memory gaps, cues, and emotional responses.
• Exposure elements: Structured confrontation of cue-related responses.
• Mindfulness: Including simple yoga poses (e.g., mountain pose) to interrupt chains of negative thought.
• Breathing exercises and muscle relaxation: Taught but left to the child’s discretion to adopt.
• Positive thought practice: Explicitly taught as a skill requiring repetition — not automatic like threat responses.

Outcomes across trials:

• Reduced PTSD, anxiety, and depression symptoms rated by both children and independent observers/parents.
• Improvements observed in parents’ own anxiety even when parents did not participate in treatment.
• Functional near-infrared spectroscopy (fNIRS) showed increased prefrontal cortex activation post-treatment, correlating with symptom improvement.

The Four-Quadrant Model

Used to analyze any stress response or behavioral episode:

1. Thoughts (cognitive)
2. Emotions (affective)
3. Physical sensations (somatic — e.g., racing heart, stomachache)
4. Actions (behavioral)

• Entry point is tailored to the child: “brainy” children start with the cognitive corner; body-
