Trauma Memories: How The Brain Protects Itself -Psychotherapy Crash Course

Overcoming traumatic stress is often about taking action. Positive action can help you overcome feelings of fear, helplessness, and hopelessnessand even small actions can make a big difference.

Volunteer your time, give blood, donate to a favorite charity, or comfort others. If formal volunteering sounds like too much of a commitment, remember that simply being helpful and friendly to others can deliver stress-reducing pleasure and challenge your sense of helplessness. Help a neighbor carry in their groceries, hold a door open for a stranger, share a smile with the people you meet during the day.

Connect with others affected by the traumatic event or participate in memorials, events, and other public rituals. Feeling connected to others and remembering the lives lost or broken in the event can help overcome the sense of hopelessness that often follows a tragedy.

How Neuroplasticity Helps The Brain Repair Itself After Traumatic Injury

Your brain is composed of over 100 trillion neural connections. When you experience brain trauma, many of the neural connections you once had become damaged or destroyed.

This explains why you might lose the ability to speak after a TBI, for example. Because the neural connections that helped you understand language have been lost.

While the brain does not generate new neurons after an injury, it can compensate for that loss by changing the way information flows throughout the brain. This is where neuroplasticity steps in.

Through neuroplasticity, the brain can form new neural pathways, and therefore repair some of the damage it sustained. It can even transfer functions that were once held in damaged parts of the brain to new, healthy areas.

Think of it as a detour on the road. If the way is blocked or destroyed, youll have to find another route. Neuroplasticity creates that route.

Ptsd patients with reduced hippocampal volume lose the ability to discriminate between past and present experiences or correctly interpret environmental contexts. Traumatic brain injury usually results from a violent blow or jolt to the head or body. However, with proper treatment, research shows the brain because studies have shown that traumatic experiences, for example, physical and sexual abuse, are so common, it is important for people to be familiar with the. Traumatic brain injuries are serious medical conditions that require careful medical monitoring and care. Traumatic brain injury and acquired brain injury. Our brain has mechanisms to protect us from traumatic memories, but sometimes, these create unexpected problems. Being that ptsd does not occur in everyone who experiences a traumatic event, these continued findings remember, your caring support after a traumatic event may make a big difference in how well and. Researchers use a variety of models for this process. In this video, i discuss concepts such as psychogenic amnesa and fugue which describe the extent the brain will go to in order to protect itself.

Cognitive Function And Brain Structure In Ptsd

Studies in PTSD are consistent with changes in cognition and brain structure. Multiple studies have demonstrated verbal declarative memory deficits in PTSD.,-

The meaning of findings related to deficits in memory and the hippocampus in PTSD, and questions related to the relative contribution of genetic and environmental factors, has become an important topic in the field of PTSD and stress research. There are three possible models, taking into account genetic or environmental factors, which have been proposed to explain smaller hippocampal volume in PTSD: Model A , Model B , and Model C .- In Model C , smaller hippocampal volume represents a premorbid risk factor for PTSD. In support of this model Pitman and colleagues have demonstrated that lower premilitary IQ is associated with combat-related PTSD, as well as finding a correlation between PTSD symptoms and hippocampal volume in twin brothers. Model A states that stress leads to damage or inhibition of neurogenesis via hypercortisolemia, decreased BDNF, or increased glutamate. Model B states that a combination of environmental and genetic factors leads to deficits in hippocampal function and structure. Showing that an intervention like medication changes hippocampal volume and cognition would provide support for at least a partial contribution of the environment to the outcomes of interest.

Sleep Disorders After Trauma


Insomnia is one of the most common sleep issues related to trauma and resolves on its own in the majority of trauma survivors. More severe and persistent sleep disorders are usually seen in people with higher levels of post-traumatic stress and PTSD. While rare, sleep disorders that may develop after trauma include nightmare disorder, periodic leg movement disorder, sleep terrors, and parasomnias such as REM sleep behavior disorder.

Effects Of Emotional Trauma On The Brain

During a stressful event, the sympathetic nervous system activates the fight-or-flight response. The stress hormone cortisol is released. Normally, when the stressor goes away, the parasympathetic nervous system responds and returns the body to normal. However, in a traumatic event, which is caused by unusually large amounts of stress, excess cortisol is released in the body. That large amount of cortisol has negative effects on the brain, damaging the CA3 neurons in the hippocampus .

Abuse And Eating Problems

“Being a victim of;abuse;has been the cause of my current eating disorder. I hope that by explaining, people will realise how things link together.”

Feelings of self-blame

People who go through trauma sometimes feel as if they are to blame. This can cause very strong feelings of shame or guilt,;even though it wasn’t your fault.

Reasons for feeling self-blame include the following:

  • It can be one way your mind tries to make sense of what has happened, and to avoid overwhelming feelings of;anger,;grief;or betrayal.
  • It’s how you’ve survived in an unsafe or stressful situation, such as living with someone who’s harmed you.
  • You wish you could have done something differently at the time, even though you couldn’t have.
  • Someone else blamed you for what happened or acted like it was your fault.
  • You were made to feel responsible for someone else’s actions, even though they had power over you .

Even though self-blame can be very hard to cope with, it can be a way your mind tries to protect you, so it might take time and support to be able to start feeling differently. You might feel confused or overwhelmed if someone else says it wasn’t your fault, although hearing this can also be a relief.

“There’s also an inherent sense that you did something wrong either that you caused what happened to you, or that you should be dealing with it better. “

The Fight Or Flight Response

Its important to understand that your fight or flight response is an automatic response. When a threat is present, the body pauses all functions that are involved in the usual rest and digest state. These physiological changes help improve the chances of survival. Some changes are increased heart and breathing rate, the release of stress hormones , dilated pupils, and increased blood pressure, to name a few. Its a total body shift to a threat response state.

As long as you can run from the threat or fight back, these physiological changes will continue. When youre caught or can no longer run or fight, you freeze. This freezing is when your nervous system is too overwhelmed to offer any other solutions to survive. This is the point where most trauma occurs.

Traumatic Memories Hidden Away

The psychology of post-traumatic stress disorder – Joelle Rabow Maletis

Memories are usually stored in distributed brain networks including the cortex, and can thus be readily accessed to consciously remember an event. But when the mice were in a different brain state induced by gaboxadol, the stressful event primarily activated subcortical memory regions of the brain. The drug rerouted the processing of stress-related memories within the brain circuits so that they couldnt be consciously accessed.

Traumatic brain injury modeling replicates aspects of traumatic brain injury as a method to better understand what physically happens to the brain. That experience proves a point. Traumatic brain injury is an important public health concern since it is one of the leading causes of death and disability worldwide. During a traumatic experience, the reptilian brain takes control, shifting the body into reactive mode. Traumatic brain injury programme online course: To better understand your brain dealing with trauma, we must look at the three major areas of the brain that deal with trauma:

Emotional Symptoms Of Traumatic Stress Include:

Shock and disbelief. You have a hard time accepting the reality of what happened, or feel numb and disconnected from your feelings.

Fear. You worry that the same thing will happen again, or that youll lose control or break down.

Sadness or grief, especially if people you know died or suffered life-altering consequences.

Helplessness. The sudden, unpredictable nature of violent crime, accidents, pandemics, or natural disasters can leave you feeling vulnerable and helpless, and even trigger anxiety or depression.

Guilt that you survived when others died, or feeling that you could have done more to help.

Anger. You may be angry at God, governments, or others you feel are responsible, or be prone to emotional outbursts.

Shame, especially over feelings or fears that you cant control.

Relief. You may feel relieved that the worst is over, that you werent as badly affected as others, or even hopeful that your life will return to normal.

If Youre A First Responder Or Medical Worker

Emergency responders and medical workers are always called upon when theres a disaster or crisis. While helping others at their time of greatest need can be extremely rewarding, it also involves many challenges and stressors.

Witnessing tragedy and suffering, making life-and-death decisions, even placing yourself in harms way, can take a toll on your mental health and cause traumatic stress. And since you may have to repeatedly deal with the aftermath of traumatic events over the course of your career, the emotional impact can snowball over time. If the stress is left unchecked, it can lead to burnout, a state of emotional, mental, and physical exhaustion.

Its important to remember that taking care of your own needs is not selfish, even at a time of crisis. Rather, its a necessity. After all, by allowing yourself to take breaks, leaning on others for support, and working in teams rather than alone for long periods, youll have the energy and fortitude to better help others in need.

Trauma And Physical Health Problems

How Trauma Can Impact The Brain and EMDR Can Help It Heal

Studies suggest that trauma could make you more vulnerable to developing physical health problems, including long-term or chronic illnesses.

This might be because trauma can affect your body as well as your mind, which can have a long-term impact on your physical health. You might also have been physically harmed during the trauma.;Having a physical illness or disability can also make you feel stressed and anxious, which might make it even harder to cope with trauma.

If you’re experiencing;physical symptoms, it’s a good idea to see your GP so they can check you over and help you access the right kind of treatment and support.

Treating Ptsd And The Brain

Although with these significant effects of trauma on the brain, fortunately, it is possible to reverse some of the symptoms. These areas of the brain can start functioning better with treatment methods that improve emotional regulation and memory. Certain medications and therapies can even bring back volume in parts of the brain that experienced loss such as the hippocampus.

In addition to regular psychotherapy there are methods like neuro-linguistic programming, hypnosis, and other therapies to help reprogram the mind and reverse changes in the brain. Even therapies like trauma-releasing exercises and body-mind techniques which help the individual reconnect with themselves may be useful in improving the brains functioning. PTSD management can help a person bounce back both mentally and emotionally from the effects of trauma.

Treatment can help all kinds of different trauma reactions, even for those that experienced trauma but have not developed PTSD. Trauma can lead to all kinds of mental health and behavioral issues including depression, anxiety and substance abuse. Many of the effects of trauma on the brain that influence a persons behavior can be reversed and minimized through regular treatment.

Coming Together: Future Research On Dissociation

Two heads are not better than one when they share the same brain. The fragmentation of mental function that can occur after a series of traumatic experiences may both protect a person from distress and make it harder for the individual to put the trauma into perspective. As we come to appreciate the complexity of neural development, we also understand that early life experiences have a profound effect on the developing brain. In dissociation, achieving a sense of mental unity is such a difficult task that it can be disrupted by events that challenge body integrity, emotional control, and the development of relationships. Future research will reveal more about specific genetic vulnerabilities that may make certain individuals especially susceptible to the disorganizing effects of traumatic stress.

As we better understand control systems in the brain that underlie dissociation, we hope to enable people so that their response to trauma does not reinforce feelings of helplessness but rather augments their control over their identity, memory and consciousness.

How Does The Brain Repair Itself After A Traumatic Injury

    Traumatic brain injury is a serious medical condition that can severely impact a persons life. Fortunately, the brain is incredibly resilient and possesses the ability to repair itself after a traumatic injury.

    This ability is known as neuroplasticity, and its the reason that many brain injury survivors can make astounding recoveries. However, neuroplasticity does not activate itself automatically. It will require your help.

    To help you optimize your brains natural repair mechanisms, this article will cover important facts about neuroplasticity after brain injury, including the best ways to engage it.

    Effects Of Pharmacotherapy On Brain Function And Structure In Ptsd

    Trauma and the Brain

    We have begun to assess the effects of pharmacotherapy on brain structure and function in PTSD. We recently assessed the effects of phenytoin on brain structure and function. Studies in animals show that phenytoin, which is used in the treatment of epilepsy and is known to modulate glutamatergic function, blocks the effects of stress on the hippocampus. We studied nine patients with PTSD in an open-label function before and after treatment with phenytoin. Phenytoin resulted in a significant improvement in PTSD symptoms. Phenytoin also resulted in increases in both right hippocampal volume and right hemisphere volume. These findings indicate that phenytoin has an effects on PTSD symptoms as well as brain structure in PTSD patients.

    We have assessed the effects of open4abel paroxetine on memory and the hippocampus in PTSD. Male and female patients with symptoms of PTSD were medication-free for at least 4 weeks before participation in the study. Twenty-eight patients were found to be eligible and started the medication phase. Of the total patient sample five patients did not finish due to noncompliance; 23 patients completed the study.

    Before patients started the medication phase, neuropsychological tests were administered, including the Wechsler Adult Intelligence Scale – Revised, WAISR , two subtests of the Wechsler Memory ScaleRevised.WMS-R, including logical memory and figural memory ; and the verbal and visual components of the Selective Reminding Test, SRT.

    People often talk about how the effects of childhood trauma can carry over into adulthood, and it is true.

    Traumatic events and experiences can have a lasting impact on people. For some people, effects will include the development of post-traumatic stress disorder symptoms that can vary in severity and sometimes hinder their lives, especially if they never receive formal PTSD treatment. For others, trauma can lead to more subtle changes in their behavior, actions, or thinking. Either way, trauma can impact people in more ways than they may realize.
