PTSD and Trauma: The Neurological Injury
Post-traumatic stress disorder is not a psychological weakness. It is a measurable brain injury—structural changes in the hippocampus, hyperactivation of the amygdala, and diminished prefrontal cortex function that can be seen on imaging and quantified in the lab. Therapy addresses the experience. We treat the damaged tissue.

Trauma Changes the Brain. We Can Measure It.
The neuroscience of PTSD has moved well beyond theory. Bremner and colleagues, in a landmark 1995 study published in the American Journal of Psychiatry, demonstrated that combat veterans with PTSD had significantly reduced hippocampal volumes compared to matched controls. The hippocampus is the structure responsible for contextual memory processing—the part of the brain that distinguishes a memory from present experience. When it shrinks, the past bleeds into the present. Flashbacks, fragmented recall, and the inability to extinguish conditioned fear responses are direct consequences of this structural loss.
Shin, Rauch, and Pitman, writing in the Annals of the New York Academy of Sciences (2006), expanded the picture. Their review synthesized functional neuroimaging data from dozens of studies, establishing a consistent pattern: amygdala hyperactivation driving exaggerated threat detection, medial prefrontal cortex hypofunction reducing the brain’s capacity to regulate emotional responses, and anterior cingulate cortex disruption impairing conflict monitoring and error detection. These are not findings unique to combat veterans. The same circuit-level dysfunction appears in survivors of sexual assault, childhood abuse, motor vehicle accidents, and other traumatic exposures.
The downstream effects reach beyond the brain itself. McEwen (2007, Physiology & Behavior) described the concept of allostatic load—the cumulative biological cost of chronic stress adaptation. Sustained cortisol elevation damages hippocampal neurons, suppresses neurogenesis, elevates inflammatory cytokines, and disrupts the hypothalamic-pituitary-adrenal axis in ways that perpetuate the stress response long after the traumatic event has ended. The body stays mobilized for a threat that is no longer present because the neural circuitry that would signal safety has been structurally compromised.
This is why cognitive approaches alone—however skilled—sometimes reach a ceiling. The patient is working with a brain that has been physically altered. The tissue needs repair, not just reprocessing.
The Neuroinflammatory Cascade of Chronic Trauma
Trauma does not only reshape circuits. It triggers a sustained inflammatory process that maintains and deepens the injury. Passos et al. (2015, World Psychiatry) conducted a meta-analysis demonstrating elevated interleukin-6, interleukin-1β, TNF-α, and C-reactive protein in patients with PTSD compared to trauma-exposed controls without the disorder. These are not transient elevations. They represent a chronic inflammatory state that degrades myelin, impairs synaptic plasticity, and accelerates cellular aging.
Mitochondrial dysfunction compounds the problem. Neurons in the hippocampus and prefrontal cortex are among the most metabolically demanding cells in the body. When chronic stress depletes NAD+, disrupts electron transport chain function, and elevates oxidative stress, these neurons lose their capacity to maintain synaptic connections and generate the energy required for neuroplasticity. The brain’s ability to adapt, learn new safety cues, and form updated memory representations depends on metabolic resources that are being systematically depleted.
This is why some patients describe feeling stuck—as though their brain cannot form new patterns despite genuine effort in therapy. The metabolic substrate that neuroplasticity requires has been compromised. Treating the inflammatory and metabolic injury creates the conditions under which psychological recovery can accelerate.
Mapping the Injury: Our Diagnostic Approach
Every PTSD evaluation at The Neurogenesis Project begins with a comprehensive neurological examination. We do not assume a uniform injury pattern. A combat veteran with blast exposure and a civilian survivor of prolonged childhood trauma will have different structural findings, different metabolic profiles, and different treatment requirements.
Dr. Orr orders advanced brain MRI using our NeuroCognitive protocol—sequences designed to evaluate hippocampal volume, white matter integrity, and cortical thickness in regions known to be vulnerable to trauma. When metabolic evaluation is warranted, brain PET scanning can reveal regional hypometabolism in structures that appear normal on structural imaging alone.
Lab panels quantify the biochemical dimensions of the injury: cortisol rhythm analysis, inflammatory cytokines (IL-6, TNF-α, CRP), mitochondrial function markers, oxidative stress indicators, and metabolic cofactors including B vitamins, magnesium, vitamin D, and thyroid function. Cognitive testing with normative comparison measures the functional deficits that imaging and labs cannot capture—processing speed, working memory, sustained attention, and executive flexibility.
The result is a detailed neurological injury map. From that map, Dr. Orr and Dr. Edwards build a treatment protocol that targets the specific pathology present in each patient, rather than applying a one-size-fits-all approach.

How We Treat This
Each therapy addresses a specific dimension of the neurological injury caused by trauma. Protocols are assembled from diagnostic findings and tailored to the individual, not applied uniformly. These treatments work alongside existing psychiatric and psychological care.
NAD+ IV Therapy
Restores the coenzyme depleted by chronic stress. Supports mitochondrial energy production in hippocampal and prefrontal neurons, reduces oxidative damage, and provides the metabolic foundation for neuroplasticity and synaptic repair.
Exosome Therapy
Delivers anti-inflammatory signaling molecules and neurotrophic factors across the blood-brain barrier. Targets the chronic neuroinflammation that sustains PTSD symptoms and impairs the brain’s capacity for adaptive remodeling.
Glutathione IV Therapy
The brain’s primary endogenous antioxidant. Intravenous glutathione reduces the oxidative burden that chronic cortisol elevation and neuroinflammation impose on vulnerable neurons, supporting cellular recovery and mitochondrial function.
Brain Health Lab Panels
Comprehensive metabolic and inflammatory biomarker analysis that reveals the biochemical dimensions of trauma injury—cortisol patterns, cytokine levels, mitochondrial markers, and nutrient cofactors that standard blood work does not evaluate.
NeuroCoaching
Dr. Edwards’ behavioral optimization program translates neurological findings into daily strategies. Builds adaptive coping frameworks grounded in each patient’s specific brain injury pattern, bridging medical treatment and functional recovery.
Related Treatments
Brain Health for Veterans
PTSD rarely occurs in isolation for veterans. TBI, blast exposure, substance use, and chronic stress compound into overlapping injuries. We evaluate and treat the complete picture.
Traumatic Brain Injury
TBI and PTSD frequently co-occur and share overlapping pathology. Our diagnostic approach distinguishes the contribution of each and builds treatment protocols that address both injuries simultaneously.
Brain-Based Recovery Coaching
Substance use and trauma are deeply interconnected. Many people with PTSD start using substances to cope. NeuroCoaching with Dr. Drew Edwards works on both sides of that pattern.

Frequently Asked Questions
How is your approach to PTSD different from traditional therapy?+
Traditional therapy addresses the psychological dimensions of trauma. We evaluate and treat the neurological injury underneath — the measurable brain changes that PTSD causes. We work alongside your therapist, not in place of them.
Read the full answer
Traditional PTSD treatment focuses on psychological processing through modalities like cognitive processing therapy, prolonged exposure, and EMDR. These are evidence-based approaches that address the cognitive and emotional dimensions of trauma. Our clinic evaluates and treats the neurological injury that underlies those symptoms. We use advanced neuroimaging to map structural and functional brain changes, inflammatory and metabolic lab panels to identify biochemical disruption, and targeted medical therapies to support cellular repair. We work alongside your existing therapist or psychiatrist, not in place of them. The goal is to treat the brain injury so that psychological therapy can work more effectively.
Can PTSD actually cause measurable brain damage?+
Yes. Research has documented hippocampal shrinkage, overactive amygdala, and reduced prefrontal cortex function in PTSD patients. These are measurable changes visible on advanced imaging.
Read the full answer
Yes. Decades of neuroimaging research have documented structural and functional brain changes in patients with PTSD. Bremner and colleagues demonstrated hippocampal volume reduction in trauma-exposed individuals as early as 1995. Shin et al. (2006) published comprehensive findings showing amygdala hyperactivity, medial prefrontal cortex hypofunction, and disrupted connectivity between these regions. These are not abstract concepts. They are measurable changes visible on advanced imaging, and they explain why patients with PTSD experience hypervigilance, memory fragmentation, emotional dysregulation, and impaired executive function. The brain has been physically altered by trauma exposure.
What does the diagnostic workup include?+
A full neurological exam, advanced brain MRI evaluating structure and connectivity, blood panels for inflammatory and metabolic markers, and cognitive testing with normative comparison.
Read the full answer
Our evaluation begins with a comprehensive neurological examination by Dr. Orr. We order advanced brain MRI using our NeuroCognitive protocol, which evaluates structural volumes, white matter integrity, and regional connectivity patterns that standard imaging overlooks. Lab panels assess inflammatory biomarkers including C-reactive protein, interleukin-6, TNF-alpha, and cortisol patterns, along with metabolic markers such as mitochondrial function indicators, B vitamins, magnesium, vitamin D, and thyroid function. Cognitive testing with normative comparison quantifies deficits in memory, attention, processing speed, and executive function. Together, these diagnostics produce a detailed map of each patient's specific injury pattern.
Is this treatment appropriate for combat veterans?+
Yes. Many of our patients are veterans with overlapping blast-related TBI, PTSD, sleep disruption, and substance use history. We evaluate the cumulative neurological impact of all of these together.
Read the full answer
Yes. Many of our PTSD patients are military veterans, and we understand the overlapping injuries that combat service produces. Veterans frequently present with a combination of blast-related traumatic brain injury, chronic PTSD, sleep disruption, and substance use history. The VA system typically evaluates these as separate conditions. We evaluate the whole brain. Our diagnostic workup captures the cumulative neurological impact of these overlapping exposures, and our treatment protocols address the shared pathology of neuroinflammation, mitochondrial dysfunction, and cortical-subcortical disconnection that drives symptoms across all of them.
How does NAD+ therapy help with PTSD?+
Chronic stress depletes NAD+ in the brain. Restoring it with IV infusions supports energy production and repair in the hippocampus and prefrontal cortex. Many patients report improved clarity, sleep, and emotional regulation.
Read the full answer
Chronic stress and trauma exposure deplete NAD+ levels throughout the brain. NAD+ is the central coenzyme in mitochondrial energy production and a required cofactor for sirtuins and PARP enzymes involved in DNA repair. When neurons in the hippocampus and prefrontal cortex are operating with depleted NAD+, they cannot produce adequate ATP, oxidative damage accumulates, and the cellular machinery responsible for neuroplasticity operates below capacity. Intravenous NAD+ restores these levels directly, supporting mitochondrial recovery, reducing oxidative stress, and providing the metabolic foundation that neurons need to repair and adapt. Many patients report improvements in cognitive clarity, sleep quality, and emotional regulation within the first course of treatment.
Does insurance cover PTSD brain treatment?+
We operate outside insurance networks. We provide superbills and documentation for out-of-network reimbursement and VA claims. Our coordinator discusses costs and payment options before scheduling.
Read the full answer
The Neurogenesis Project operates outside of insurance networks. Our diagnostic and treatment protocols use therapies that are not typically covered by commercial insurance plans, Medicare, or VA benefits. We provide detailed superbills and medical documentation that patients can submit to their carriers for potential out-of-network reimbursement. For veterans, we can provide documentation to support VA claims related to service-connected conditions. Our patient coordinator can discuss costs, payment plans, and documentation options before you schedule.
Is NAD+ IV therapy FDA-approved for PTSD?+
No. NAD+ is not FDA-approved for PTSD or any specific disease. The rationale is based on the neurobiology of how chronic stress depletes NAD+ and impairs brain cell energy production. We are transparent about this.
Read the full answer
No. NAD+ is not FDA-approved for PTSD or any specific disease. Our rationale is grounded in the neurobiology: chronic stress depletes NAD+ and impairs mitochondrial energy production in the prefrontal cortex and hippocampus. Restoring NAD+ supports the cellular energy these regions need to function. This is a mechanistic rationale, not an FDA-approved indication. We are transparent about this distinction.
Can this treatment help with PTSD that was not caused by military service?+
Yes. PTSD produces the same neurological injury pattern regardless of the cause. We treat civilian trauma from accidents, assault, childhood adversity, and medical events with equal frequency.
Read the full answer
Yes. PTSD is a neurological injury pattern regardless of the source. Motor vehicle accidents, assault, childhood adversity, medical trauma, and first-responder exposure all produce the same neurological picture. The diagnostic workup and treatment protocol are the same. We treat civilian and military PTSD patients with equal frequency.
Do you offer TMS or neurofeedback for PTSD?+
Not at this time. If TMS looks like a good fit after your evaluation, Dr. Orr can refer you to a TMS provider and coordinate your care.
