According to Nexus Neurorecovery Center – San Antonio CEO Christa Brantley, MA, LPC, LCCA, trauma follows a dose-response pattern — the more you’re exposed to, the greater the impact on every aspect of your wellbeing. Trauma-informed care reframes the patient experience, shifting the focus away from blame or pathology and toward understanding the circumstances that shaped a person’s health. Instead of asking “What’s wrong with you?” it asks “What happened to you?” — validating experiences while creating a safe foundation for healing.
In this article, we’ll explore how trauma affects the body and brain, the pillars of trauma-informed care, and therapies proven to support recovery and resilience.
How trauma impacts the body and brain.
Trauma not only leaves emotional scars, but also changes biology. Researchers have shown that the more adverse childhood experiences (ACEs), or traumatic events, someone has experienced, the higher their risk for chronic diseases and behavioral health concerns. The landmark CDC–Kaiser Permanente ACE Study1 revealed strong links between ACE scores and conditions such as heart disease, diabetes, and depression.
Neurologically, trauma activates the brain’s survival systems, often leading to an overactive amygdala — the brain’s “alarm bell” — and a shrunken hippocampus, which stores memory and helps regulate stress. Psychiatrist Bessel van der Kolk describes this phenomenon in The Body Keeps the Score, noting that early trauma can become “stored” in the body, resurfacing later as chronic pain, anxiety, or other somatic symptoms.
The need for a whole-person approach to care.
Because trauma affects both the mind and body, treatment must go beyond symptom management. Trauma-informed care begins by validating what patients feel, even when those symptoms cannot be explained by standard medical tests. This is particularly important for conditions such as psychogenic nonepileptic seizures (PNES), which can be dismissed as “pseudo” disorders despite their very real impact.
A whole-person approach integrates medical and behavioral care. The Substance Abuse and Mental Health Services Administration (SAMHSA) highlights this collaboration as essential, encouraging providers to work across disciplines so patients receive care that addresses their physical, emotional, and psychological needs simultaneously.2
Core principles of trauma-informed care.
Trauma-informed care offers a framework built on key guiding principles. These principles help providers create environments where patients feel safe, understood, and supported — laying the groundwork for meaningful healing.
Address physical symptoms early.
One of the first steps is addressing what can be quickly stabilized, often beginning with physical symptoms. When issues like migraines, gastrointestinal distress, or fatigue are treated, patients experience immediate relief and begin to feel safer. Physical stabilization can help build trust with care providers and create momentum for deeper emotional work.
Teach regulation before insight.
Patients with complex trauma may struggle to recognize or name their emotions. Before exploring the “why” behind their experiences, it’s critical to help them regulate their nervous systems. Grounding exercises, mindfulness practices, and body-awareness techniques help reduce emotional flooding and prepare the brain for insight-driven therapy. Interventions such as dialectical behavior therapy (DBT) and cognitive behavioral therapy (CBT) have been shown to significantly reduce trauma-related distress.3
Rewire to compensate for missed milestones.
Trauma that occurs during key developmental periods can disrupt normal growth, leaving gaps in foundational skills such as trust, emotional regulation, and social engagement. Trauma-informed care works to “re-wire” these experiences by introducing structure, routine, and rhythm. Psychiatrist Bruce Perry’s research shows that rhythmic, repetitive experiences can repair disrupted neural pathways and promote recovery.4
Provide consistency and structure.
Predictability and compassion are powerful tools for healing. Creating a consistent daily structure helps patients move out of hypervigilance or emotional shutdown and into a state where connection and balance are possible. Safety and predictability are cornerstones of lasting recovery.
Treatments and therapies.
Advances in treatment are helping clinicians approach trauma from multiple angles. Eye Movement Desensitization and Reprocessing (EMDR), for example, uses bilateral stimulation to help patients reprocess traumatic memories in a calm, almost meditative state. Studies have shown EMDR to be highly effective for post-traumatic stress disorder and complex trauma, particularly for individuals who struggle to verbalize their experiences.5
Pharmacological innovations are also expanding the field. Ketamine-assisted therapy for treatment-resistant depression and MDMA-assisted therapy for PTSD are being studied for their ability to unlock neural pathways and allow patients to process traumatic memories without being overwhelmed by fight-or-flight responses. Though not yet mainstream, these approaches are sparking important conversations about the future of trauma therapy and the role of neuroscience in mental health care.
Why early intervention is crucial.
Early support can dramatically reduce the long-term impact of trauma. Pediatrician Dr. Nadine Burke Harris famously likens children who experience chronic trauma to “sports cars that are always revved up.” This constant state of activation can wear down the body, leading to chronic illness and emotional dysregulation later in life. When children receive timely intervention — therapy, coping skills, and a consistent support system — those risks can be greatly reduced.
Putting trauma-informed care into practice.
Healing from trauma requires more than a diagnosis; it requires seeing the whole person. At Nexus Health Systems, interdisciplinary teams put these principles into action every day, validating patient experiences, bridging medical and behavioral health, and creating structured environments that foster safety and connection. As Brantley explains, the ultimate goal is to help patients “recalibrate after traumatic experiences, thereby mitigating or even reversing their impacts.”
If you know a child or teen living with trauma-related medical or behavioral symptoms, support and understanding can make all the difference. Nexus’ admissions team helps families and providers identify the right care setting for each individual’s needs. Contact us to learn more or refer a patient.
