The Body in Stress & Trauma
The brain and the body are parts of a common interactive system. Any outside stimulus or input to the brain must first be registered by the sensory organ systems of the body, and the brain relies on the body to provide all information having to do with function in general, not just survival. What’s happening in the body continuously changes the brain. The flip side of this relationship is that the brain, in response, also directs and changes the body. Learning of a motor skill by the brain is dependent on the body’s ability to adapt and respond to feedback messages from the brain that direct the somatic musculature. The muscles of the viscera—the organs of the chest and abdomen—also operate through messages from the autonomic nervous system that are generated by the brain, while the sensory messages from these visceral organs inform the brain about one’s emotional well-being. The relative health of the brain depends on the health of the body, and vice versa. If trauma has adversely affected either one, you’ve got to find a means of healing that incorporates both brain and body. You can’t fix one without fixing the other.
We’ve seen how stress and trauma place their own unique imprint on brain function. The spectrum of negative life experiences directly affects how the brain functions, and in some cases actually produces negative physical changes, such as the loss of neurons in the hippocampus through the effects of cortisol, the stress hormone. Stress and trauma can “damage” the brain. It should come as no surprise, then, that abnormal ways that the brain functions in stress and trauma might also “damage” the body. This particular concept has been around for quite a while in the medical field, giving rise to what we now call mind-body medicine, complementary medicine, and in some cases, alternative medicine. The therapeutic approaches employed by this field of practice often incorporate techniques derived from the practice of medicine in the Far East. Examples include meditation, acupuncture, herbs, massage, Qigong, and tai chi, as well as ayurvedic medicine and yoga from India. Most of these practices seek to balance the mind, body, and spirit as a means of preventing and healing disease. This concept certainly has appeal if the primary negative effects on the body in stress and trauma are at least in part due to a disruption in homeostasis, which intrinsically implies a disruption of balance and regulation of brain and body.
There’s a dilemma that Western medicine seems to have in dealing with diseases related to brain function, especially alterations in homeostasis. Allopathic, or Western, medicine depends to a significant degree on measurements of the body’s chemical/physiological state at a fixed point in time. X rays, scans, microscopic images, blood tests, and so on represent a picture of the body frozen in the moment of the test. One can monitor a person’s heart rate, blood pressure, blood-oxygen level, and brain waves for a longer period of time, but this is costly and only gives a brief picture of what we might call the state of homeostasis. Homeostatic disruption almost by definition is associated with emotional disruption and distress. This emotional component often leads the allopathic physician to designate the medical syndromes of trauma as “psychosomatic” diseases, with an emotional and not a physical cause. I think a more accurate term would be “neurosomatic” diseases, as these disorders are related to abnormalities in the balanced function of the brain and autonomic nervous system. Although the abnormal body states in trauma are hard to pin down with tests, they still are quite real and definitely are “physical.” And this dilemma of a changing, unstable state of abnormal physiology and its symptoms is primarily what we’ll be dealing with in considering the body in stress and trauma.
In this article, I’ll review in detail the effect of cortisol on many of the body’s systems, a syndrome Hans Selye called the “general adaptation syndrome,” or GAS. The GAS primarily describes what have been called the diseases of stress. We’ll also be dealing with a number of diseases and medical syndromes that are prevalent in victims of life trauma but depart from the illness of the GAS. The medical syndromes that I relate specifically to trauma reflect the alterations in brain function that occur in trauma. These include “false” body-based procedural memories, persistence of dissociative freeze states, and neurosensitization, or kindling. Obviously many of these syndromes of trauma represent disorders of regulation of the autonomic nervous system, and therefore involve the visceral organs. I’ll also be exploring syndromes and diseases that reflect the frozen somatic procedural memory that characterizes the brain in trauma. This produces not only stuck emotions but also body states reflecting how the brain/body tried to protect itself in trauma. These body states are now frozen as “false” implicit memories—false because they represent memories for an event in the past that is perceived as still being in the present. Many posttraumatic body disorders reflect the kindled, sensitized nature of the brain, leading predictably to syndromes of hypersensitivity to many sensory stimuli. These sensitization disorders, which I call syndromes of kindling, may involve one or more of the body senses. And many trauma syndromes reflect the process of dissociation, or cutting off from awareness, of regions and parts of the somatosensory body that tried but failed to protect the trauma victim.
Cortisol and the Diseases of Stress:
The Price of Adaptation
Stress basically demands that the brain and body adapt to a stressor—an event or experience that disrupts homeostasis but is not sufficient to trigger the full-blown fight/flight response. There’s an element of arousal in this process, though not as extreme as that in the fight/flight response, and the amygdala is mildly activated when the brain senses messages that imply even a subtle threat. There is a continuum between stress and trauma that is mainly defined by the degree of helplessness the person is experiencing. In fact, the escalation of a stressor to actually being a life threat is entirely possible. But if the stressor continues without ever becoming a life threat, the brain takes a different pathway than it does in trauma to adapt. This pathway is basically the same as the sympathetic nervous systems relationship to the hypothalamic-pituitary-adrenal (HPA) axis. The HPA axis is the origin of the hormonal response by the body’s endocrine system to prepare the body to adapt to a stressor as long as it persists. The end result is the release of cortisol from the adrenal cortex, or outer layer of the adrenal gland.
Cortisol damages the neurons of the hippocampus and can contribute to memory and cognitive problems in trauma victims. In large amounts, it may also affect the cerebral cortex, producing arousal, vigilance, delusions, anxiety, rage, and even psychosis. As long as the stressor remains present, cortisol will remain elevated in order to help the body deal with the ongoing, low-grade threat. This state of threat will result in the gradual development of the GAS. Helping us maintain vigilance in the face of low-grade threat, the GAS state of autonomic tuning promotes the ability of our heart and circulatory system to deal with increased physical demands and our level of blood glucose to meet the increased caloric energy demands of the body and especially the brain. In the relatively short term, it promotes survival, but in the longer term it literally causes a breakdown of the body.
Cortisol also acts as a modulator of the immune system. In high amounts, it suppresses the immune system. In the early days of organ transplantation, chemicals related to cortisol were used to suppress the immune system to prevent organ rejection. Cortisol-related drugs have also been used in autoimmune diseases, such as rheumatoid arthritis, lupus, and multiple sclerosis. Autoimmune diseases are inflammatory in nature, and cortisol also suppresses inflammation. But improvement in the autoimmune diseases with cortisol is associated with the destructive effects of the GAS. Suppression of the immune system unfortunately also makes the person more prone to what are called “opportunistic” infections by bacteria and viruses that aren’t normally very infectious. If taken for a lengthy period of time, cortisol also can contribute to the development of unusual forms of cancer that are generally held in check by the immune system. In many ways, prolonged exposure to cortisol leaves the person subject to many of the tumors and infections seen in the immune deficiency caused by the AIDS virus. As a result, during prolonged stress, persons are vulnerable to the development of viral diseases. That’s why cold sores are common under stress.
Cortisol also causes the kidneys to reduce their excretion of salt in the urine. Retaining salt causes blood volume to increase, an important piece of survival insurance in case the threat becomes physical and the person experiences injuries causing a loss of blood. Increased blood volume also guarantees the brain’s access to circulation. Both of these effects are adaptive measures for dealing with stress in the short term. Cortisol also raises blood pressure, during both exertion and rest, and increases baseline pulse rate, both of which ensure maximal blood flow to the brain. It causes a significant increase in blood glucose levels. The brain counts solely on glucose as a source of energy. Increased vigilance, glucose, blood pressure, pulse, and blood volume help provide support for blood circulation and optimal oxygen and nutrients for brain function—in the short term.
But cortisol also causes an increase in serum cholesterol and other lipids. It causes an increase in secretion of stomach acid. You are probably beginning to see the price exerted by the adaptive GAS. Elevated blood pressure may contribute to sustained hypertension and stroke. Sustained elevated blood sugar may trigger clinical diabetes. Elevated blood lipids may lead to atherosclerosis and coronary artery disease. Immune suppression may lead to opportunistic infections and conceivably cancer. Elevated stomach-acid secretion may lead to peptic ulcers. Increased vigilance can lead to mental disorders, especially mania and psychosis.
Finally, cortisol in the long run is catabolic—it breaks down and changes tissues. It causes wasting of muscles, increased fat deposition about the abdomen, osteoporosis, swelling of the face, and the masculine effects of acne and increased facial hair growth in both genders. Many of these conditions have been called “the diseases of stress,” and, in fact, this is partly true. During the early stages of recovery from serious injuries, many of my rehabilitation patients manifested some of these conditions, especially hypertension, acne, cold sores, weight gain, and hypervigilance. Usually these conditions spontaneously subside with time. But if prolonged, the adaptive GAS comes at considerable cost to the brain and body.
Unfortunately the burden of the GAS may not always subside, progressing instead to the diseases and syndromes of trauma. The element of helplessness in an ongoing stressful situation may grow with the passage of time. The burden of financial loss, litigation, impairment of human relationships, and increasing social isolation may cause a shift in brain and body physiology. In this context, a significant number of my injured patients went on to develop what I’ve called the diseases of trauma, syndromes increasingly at the parasympathetic end of the spectrum of autonomic dysfunction.

Integrating Knowledge Into Practice
with Matthew Dahlitz
We All Need Integration
We all know about the pressures of our profession, we tell our colleagues to be mindful of workload, we wonder why friends and colleagues took so long to get some help.
It's a simple fact that the mental health professions are at a high risk for burnout, vicarious trauma, and other stressors about clients, systems, and money.
I Can Help
After a decade of producing and developing The Neuropsychotherapist and The Science of Psychotherapy I have engaged with, published and brought into our Academy expert contributors from around the world. This has given me a wide ranging, interdisciplinary knowledge that can be of great value to you. The real key is to know how to integrate that knowledge into your professional practice. Together we can "join the dots" in your practice and life in areas like:
- the science of your practice
- integrative practice and approach
- burn out | vicarious trauma
- imposter syndrome
I'm making myself available to anyone in our Science of Psychotherapy community, wherever you are in the world, for online counseling and consultation. I won't replace your supervisor, but I can be a valuable human resource for you.
How: Online video conferencing using Zoom
We all need support. I look forward to connecting with you online whenever you need.
My question is if PTSD or cptsd is not treated with meds and it is severe does the constant state of vigilance run the risk of the person getting worse and lead to psychosis or episodes of psychosis? If so should these people be on meds for life? Is there any hope for these people?
Hi Corey. A constant state of anxiety driven vigilance is obviously distressing and can be damaging to the hippocampus, restricts new learning, and reinforces “limbic loops” of avoidance orientated schemas (mental models of self and the world)—basically a downward spiral of anxiety. Will this lead to psychosis? Well that depends. Does the individual have genetic, biological and/or psychosocial predispositions to psychotic episodes? If so, maybe prolonged stress could trigger episodes. To be honest, I don’t know enough about the aetiology of psychotic disorders to give you a good answer. Medication can provide a useful reprieve from symptoms and give the patient enough head space to engage in some form of therapy (psychotherapy, sensorimotor psychotherapy, etc) to deal with the underlying anxiety response and form new, adaptive coping mechanisms. In my experience talking therapies, somatic therapies, even neurofeedback therapies, are essential part of recovery – not just drug therapy. And no, they don’t need to be on meds for life, and yes, there is hope. Finding an experienced trauma therapist is the first place to start.
Thank you very much for your answer I have bee been following your Facebook page and reading to learn as much as possible. I have been diagnosed with generalized anxiety, depression and cptsd I see a psychiatrist and psychologist. A few months back my anxiety was extreme and also stopped a small dose of antidepressants when I shouldn’t have I didn’t sleep for five days and started to get paranoid and felt very strange since then I have explained and asked my psychologist and psychiatrist if this was a psychosis and psychiatrist didn’t believe so psychologist thought maybe a Depression with just a small touch of symptoms but I can’t get past it. It is very upsetting to me. I continue with antidepressants as well as seeing my psychologist it seems things have reached a higher level since I started therapy the depression and anxiety are more.I appreciate the info I am glad to hear there is hope.
Stay engaged with your psychologist Corey – there is light at the end of the tunnel! Sometimes it can feel like a hopeless uphill battle but I’ve seen enough people come out the other side to know it’s a battle you can win. It’s difficult, if not impossible, to do alone, so lean on your professional help and the ones whom you feel safe with.
Yes there is hope. The body has a mechanism to heal trauma and release stress. I used it myself to cure my PTSD. One thing I liked about it was that it’s a self-healing tool, once properly trained it it. That means less cost to me, and I can use it when I need it without having to wait for whatever time a therapist has for me. Another thing I liked, and discovered, was that stress and trauma are primarily in the body, not my prefrontal cortex. Talking might be beneficial, but will never release what is in the body. See the second sentence. That mechanism predates talk therapy by a couple million years. I started working on my C-PTSD/PTSD in 2013, and by and large am symptom free today. I was however, aggressive with the tool, had some shitty months coming out of freeze into the PTSD, and then having to fine tune my use of this mechanism, and once it released, the symptoms abated steadily until today.
It was Dr. Scaer who set me out on this path, interestingly enough.
What was the tool / approach you found beneficial Leckey?
Tension and Trauma Releasing Exercises (TRE®). Created by Dr. Berceli. Raise Your Resilience dot com has more info as well as trauma prevention dot com.
I love TRE. It has helped my ptsd a lot. I’m still not sleeping though. Did you find TRE is cumulative the longer you do it over time?
Like stress, yes, it creates deeper resilience. I tend to use the concept of pulsating, which the body actually does. The metaphor aspect is for parts that we typically think might not pulsate.
Pulsation has a contraction phase, and an expansion phase. As resilience in the neurology develops, the expansion phase gets bigger as it were, so relatively, the contraction phase does not because it doesn’t need to. It still happens, but I’ve discovered that rather than being uncomfortable, I appreciate it. Sort of like pulling back to recharge. The expansion of cognition, consciousness and emotion I don’t think have boundaries, other than in the issue of being embodied. I haven’t yet gone beyond that, but I’ve had higher levels of what I call bliss. It’s quite astounding.
How is sleep an issue? And if you’d like, I can be reached via the website in my comment above.
Hi, I have a question about cortisol. As some who is now in my 40’s with extensive trauma history. I am facing many health issues and the mention of cortisol got me wondering. Can the effects of the trauma/cortisol cause a breakdown of the adrenal system? I have bouts of being dizzy, tired and nauseous quite frequently. I always thought it was the flu and paid it no mind. I have searched the inter webs and seemed like it could be Addisons disease which I believe is effected by cortisol breakdown. I reached out to my doctor hoping to get some answers of why I am feeling so ran down all the time. However when one has a mental health diagnosis it makes it harder for doctors to take the patient seriously. In fact my last doctor appt I was told to seek a psych doctor and in my chart the symptoms I am experiencing is similar to untreated mental illness. Which is wrong and what is called diagnostic overshadowing and a form of discrimination. My struggle now is to find a doctor who will see me and not my mental illness. You would think in todays day and age primary doctors would understand the effects trauma has on the body but they don’t 🙁
Rey you are probably best to seek out a naturopathic doctor if you are not satisfied with the advice/care your GP is giving you. Chronic elevation of cortisol can damage the “thermostat” mechanism of the Hypothalamus-pituitary-adrenal axis (the stress response system) and regulation of the stress response is more difficult. This can lead to what’s commonly known as adrenal fatigue. In a complex system like the human body things are rarely a single cause and effect – there’s likely multiple things going on in your body to produce the symptoms you are experiencing and this is where a holistic approach of a trauma specialist (in your case) and naturopathic doctor, working together, is best. Aetiology can be difficult to pin down because of the fact that biological/neurological/environmental factors can elicit mental health issues and mental health issues can affect our biology/neurology/environment. With complex trauma, I believe you need a specialist for your mind and one for your body. Keep up the search for professionals who will understand where you are and what you need – they are out there and they can make a big difference!
Is there a relation between stress & your balance?
