Trauma is an emotional reaction to a distressing event, but what does emotional trauma do to the brain? When a person experiences trauma, their brain shifts into high alert. All of their mental and physical functions focus on dealing with the threat. Experts often describe this state as the “fight or flight” response. In most cases, this state of high alert fades once the threat is gone and brain chemicals return to normal. For some people, the effects of trauma linger and can affect their long-term mental and physical health.

Trauma is an emotional reaction to a distressing event, but what does emotional trauma do to
the brain? When a person experiences trauma, their brain shifts into high alert. All of their
mental and physical functions focus on dealing with the threat. Experts often describe this state
as the “fight or flight” response.
In most cases, this state of high alert fades once the threat is gone and brain chemicals return
to normal. For some people, the effects of trauma linger and can affect their long-term mental
and physical health.
What is Emotional Trauma?
Emotional trauma (https://integrativelifecenter.com/what-are-the-symptoms-of-emotional-
trauma/) can occur after a distressing event or series of events that make you feel unsafe.
What constitutes a traumatic event is specific to the individual and may not be the same for
everyone. If you feel frightened, unsafe, helpless, or that your life is threatened, you’re likely
experiencing a traumatic event.
“Trauma shatters a person’s sense of safety and many people have difficulty processing what
happened to them and returning themselves to their previous state of calm,” Irving Najman, MA,
LMFT, CSAT, Clinical Manager at Integrative Life Center said.
Both one-time events and ongoing experiences can be traumatizing. For example, military
veterans in combat are at risk of developing severe trauma responses, but many different
events can cause a person to feel traumatized.
Examples of traumatic happenings include:
Accident/injury
Loss of a loved one

2. Natural disaster
Serious or chronic illness
Attack, assault, or witnessing a violent attack
Childhood abuse or neglect
Rape or sexual abuse
Extreme poverty
Bullying
Domestic violence or witnessing domestic violence
Racism
It’s not necessary to experience a traumatic incident yourself to be traumatized by it.
Repeatedly hearing about traumatic events can also be traumatizing.
“People can experience emotional trauma from living in an environment with people who
haven’t processed their own emotional trauma and are, therefore, in a seemingly constant
state of arousal. They don’t feel safe, so they teach others to live that same way,” Irving explains.
What Does Emotional Trauma Do to the Brain?
The answer to the question, “What does emotional trauma do to the brain?” is complex because
trauma affects all three parts of the human brain: the reptilian, the mammalian, and the
neomammalian.
The Reptilian Brain
The reptilian or primal brain is the part of the brain known as the basal ganglia
(https://en.wikipedia.org/wiki/Basal_ganglia). The basal ganglia structure handles survival. It’s
in charge of feeding, fighting, and fleeing.
The amygdala is also in this area of the brain. It’s in charge of fear response and the production
of cortisol. Repeated exposure to fear, even imagined or remembered fear, as can be the case
with trauma, can decrease the size and function of the amygdala.
The Mammalian Brain
The mammalian part of the brain is also known as the limbic system, which handles your
feelings and emotions. It’s the brain’s reward center. Neurons in this region produce your body’s
“feel-good” chemicals like dopamine.
The hippocampus is also a part of the mammalian brain. If a sight or scent has ever triggered a
strong memory for you, that’s your hippocampus at work.
If you live with Post-Traumatic Stress Disorder (https://integrativelifecenter.com/therapy/pstd-
treatment/) or other trauma-related disorders, you may experience frightening “flashbacks.”
The hippocampus triggers these vivid memories. They’re your brain’s way of keeping you awake
and vigilant for danger, even when there isn’t currently danger.
Neo-Mammalian Brain
Higher mammals, like humans, also have a cerebral neocortex. Professionals sometimes refer
to it as the neo-mammalian brain. The functions of the cerebral neocortex include decision-
making, problem-solving, sensory processing, and memory.
When a person experiences trauma, it can stop the right and left hemispheres of their brain
from communicating properly, which can impact memory and other neocortex functions.
The Daily Impact of Trauma on Your Health
Trauma can affect your health on many levels. When an ongoing stressor occurs, it overwhelms
the nervous system and can result in physical and mental health symptoms.
“Your mind and body are connected. They don’t act independently of one another. Therefore,
trauma is stored in both, and you have to heal from it holistically,” Irving stated.

3. Researchers estimate that about 70% of U.S. adults have experienced at least one traumatic
event. About 20% of this group will meet the criteria for PTSD, the most severe of the trauma
disorders.
Some of the potential impacts of trauma on health
and wellness include:
Chronic pain
Headaches
Guilt or shame
Depression
Insomnia and other sleep disturbances
Avoiding people, places, or things that remind you of the trauma
Poor self-esteem and lack of confidence
Unexplained rage or anger
Feeling hypervigilant and easily startled
Extreme mood swings
Substance or alcohol use disorder (https://integrativelifecenter.com/addiction-
programs/)
Chronic stress
Chest pains
Brain damage (memory loss, overstimulated amygdala, shrunken hippocampus)
Various mental health disorders are also associated with trauma. In addition to PTSD,
unresolved trauma may lead to anxiety disorders, depression, Borderline Personality Disorder,
and dissociative disorders.
Trauma symptoms can begin shortly after the triggering event(s) or may not appear until years
later.
Healing Trauma and the Brain
Fortunately, qualified professionals can help identify disorders or conditions caused by
emotional trauma. Treatment for trauma (https://integrativelifecenter.com/therapy/trauma-
treatment/) is well-researched and effective.
“You can heal from trauma and reestablish your feelings of safety and self efficacy,” Irving said.
Some of the most commonly used treatment modalities can even help reverse the damage
caused by trauma.
Eye-Movement Desensitization and Reprocessing
Eye-Movement Desensitization and Reprocessing (EMDR) therapy differs from most other
therapies. The goal of this approach is to change how the brain stores memories. EMDR has
eight phases to help a client reduce the emotional impact of traumatic memories.
The therapist will lead the client through the phases of EMDR by asking them to remember the
memory. They will also ask the client to do some tapping motions or eye movements. The client
may repeat this step several times until they feel less emotional pain when they think about the
specific memory.
Cognitive-Behavioral Therapy
Cognitive-Behavioral Therapy (CBT) (https://integrativelifecenter.com/therapy/cognitive-
behavioral/) is traditional talk therapy that focuses on changing negative patterns of thinking
and behaving regardless of the past or what caused the patterns to develop.
CBT is a short-term therapy method that typically lasts only a few months. Clients usually do
regular “homework” assignments to practice their new positive-thinking skills.

4. Dialectical Behavior Therapy
Dialectical behavior therapy (https://integrativelifecenter.com/therapy/dialectical-behavior/)is
a kind of CBT. It focuses on living in the moment instead of dwelling on the past or worrying
about future events. The word “dialectical” means opposing ideas. The goal of DBT is to help
clients accept the present while they also work to improve their outcomes.
Trauma-Informed Therapy
Trauma-informed therapy can be a collection of specific treatments. It is not the specific
therapy but the approach that defines trauma-informed therapy.
This approach assumes the client has experienced trauma even if the actual event or events
are unknown. The goal of this approach to care is to avoid re-traumatizing a person. Trauma-
informed therapy promotes self-empowerment and personal choice in care options.
Integrative Life Center uses a trauma-informed approach as part of our core treatment
philosophy (https://integrativelifecenter.com/treatment-philosophy/).
Brainspotting
Brainspotting (https://integrativelifecenter.com/brainspotting/) is a technique that uses eye
position to access trauma stored deep in the brain. A therapist will direct you to focus your gaze
on a point that is related to that experience and explore emotions that you may feel as you do
so. Music can also be used. This can lead to the healthy processing of that trauma.
Comprehensive Resource Model Therapy
Clinicians developed the Comprehensive Resource Model
(https://comprehensiveresourcemodel.com/) (CRM) for people with severe PTSD and other
trauma-related disorders. It is a neuro-biologically based treatment. CRM includes various
methods that can clear the neurobiological “debris” that gets in the way of the brain’s healthy
function.
