It is highly likely that at some point in your life, you will encounter trauma either first-hand or vicariously (Fisher, 2023). In fact, about 90% of all adults will experience trauma at least once in their lifespan (Kilpatrick et al, 2013). While you may know what trauma is, do you know what happens to your brain when you are traumatized?

What Happens To The Brain with Trauma?
Understanding what happens to your brain can help you to heal from trauma. If you can visualize and understand what has happened to your brain, you can then also visualize its healing process (Rosenthal, 2015). Healing involves understanding what has occurred and then rewiring and retraining your brain. Dealing with traumatic experiences is not just about dealing with the past and what has happened. It is also about becoming fully present in the moment and being able to visualize a future for yourself.
When a person experiences a traumatic event, three main parts of the brain respond (Bremner, 2022; Fisher, 2023). The parts of the brain affected by the experience are the:
- Prefrontal cortex
- Amygdala
- Hippocampus
Traumatic stress is associated with lasting changes in these brain areas (Bremner, 2022). What does that mean? Put simply, when a trauma is experienced, the brain rewires itself to deal with the trauma (Bremner, 2022; Fisher, 2023). Therefore, the brains of people who have experienced are actually different. Scientists can actually see physical differences in their brains’ appearances and functioning (Jeong et al., 2021).
Those who have been traumatized are often in a prolonged state of hypervigilance and their memories are suppressed. These individuals often have an overstimulated amygdala and an underactive hippocampus. The physical changes in the brain often lead to mental health struggles and illness (Jeong, 2021). This could include Post Traumatic Stress Disorder (PTSD), anxiety, and depression (Bremner, 2022).

What does trauma do to your body?
According to Fisher (2023) and Van der Kolk (2015), PTSD can manifest itself through an individual experiencing:
- Panic
- Flashbacks
- Nightmares
- Startle responses
- Preoccupation with the traumatic event
According to Jeong (2021), studies have shown that individuals who have been traumatized often have issues with:
- Emotional regulation
- Executive functioning
- Cognitive functioning, specifically attention
Where is trauma stored in the body?
The prefrontal cortex is the part of the brain that witnesses the traumatic event (Fisher, 2023). It’s the part of the brain that helps us make choices. When a trauma is experienced, a person may enter into a fight, flight, or freeze state. This can result in the shutting down of the prefrontal cortex (Fisher, 2023). This explains why it’s difficult to make decisions in the heat of the moment.
The hippocampus is the brain’s “filing cabinet” which organizes, contextualizes, and sequences events. This part of the brain can be damaged by chemicals in the brain that get released during the body’s stress response to trauma. When the functioning of the hippocampus is impaired, it can keep traumatic memories especially vivid in our minds (Van der Kolk, 2015).
The amygdala holds our implicit and emotional memories (Fisher, 2023). It’s the part of the brain that detects fear and recognizes threats in our environment. After a traumatic event, the amygdala may be so hypervigilant that it perceives threats nearly everywhere. Implicit memory is memory that is stored unconsciously and isn’t stored purposely. Implicit memories cannot consciously be brought into awareness (Fisher, 2023). This is why many survivors of trauma have memories from the trauma stored in their brains that they’re not even aware of.
How does the brain protect itself from traumatic experiences?
When one or more parts of the brain are affected by a traumatic event, this can affect a trauma survivor’s functioning. Oftentimes times this explains why a trauma survivor may have trouble remembering events in order. They may also have difficulty vocalizing what happened to them. Our memories are scattered throughout our brains, and therefore it takes good calibration of all parts to have us function at our very best. When someone is affected by trauma, their brain’s calibration is off. This causes deficits in their functioning (Fisher, 2023; Rosenthal, 2015).

Does trauma permanently affect the brain?
The good news for trauma survivors is that the effects of trauma on the brain can be reversed (Rosenthal, 2015). Individuals who have survived traumatic events can work toward reprogramming their body and mind. They can learn to respond differently to triggers. How, you might ask? The answer is therapy with a qualified licensed professional who specializes in trauma.
Through trauma therapy in New Jersey, you can learn how you are separate from your symptoms. You can learn why you have been dealing with neurophysiological processes that were out of your control (Rosenthal, 2015). Therapy can also help you renegotiate your sense of identity and envision who you want to be (Fisher, 2023). Knowledge is power and understanding what has happened to you is a huge first step in regaining control of your life.
If you are looking for a great book that details trauma and the brain, I recommend The Body Keeps the Score by Bessel van der Kolk published in 2015. This book gives great insight into the trauma field and how it came to be what it is today. The book explains how PTSD manifests itself years after a traumatic event. It also provides information on how the brain is affected by trauma and how the body and mind are connected in a very special way.
Should you consider trauma therapy in New Jersey?
People often race to a physician’s office when they feel troubling physical symptoms such as chest pain, dizziness, or a rapid heartbeat. Likewise, when we feel sadness, depression, anger, or anxiety, we should consider seeing a therapist. Just as the various parts of our physical bodies need periodic testing and evaluation, the mind needs to be cared for and monitored, too.
Professional support, such as therapy, can play a vital role in healing. Trauma therapy in New Jersey provides empathetic guidance, gradual exploration, and a compassionate approach to self-discovery. With these tools, you can forge a path forward. You can find acceptance, resilience, and healing from the haunting grip of trauma.
