Can brain trauma be cured?

Levels of recovery following brain injury are heavily influenced by the individual and how their body reacts. Even mild concussion can lead to lifelong effects, while people suffering moderate to severe brain injuries can make close to a full recovery.

What is the most common type of traumatic brain injury?

Concussion is among the most common forms of TBI. A concussion can happen when the head or body is moved back and forth quickly, such as during a car crash or sports injury, or from a blow to the head. Concussions are often called “mild TBIs,” because they are usually not life-threatening.

Types of TBIsConcussions.Contusions.Penetrating injuries.Anoxic brain injuries.

How long does it take to recover from a traumatic brain injury?

The vast majority of recovery after traumatic brain injury takes place in the two years after injury; after this the brain injured patient faces an uncertain future. In some patients further improvement is seen even as late as 5-10 years after injury.

What is the best treatment for traumatic brain injury?

Mild traumatic brain injuries usually require no treatment other than rest and over-the-counter pain relievers to treat a headache. However, a person with a mild traumatic brain injury usually needs to be monitored closely at home for any persistent, worsening or new symptoms.

Is traumatic brain injury permanent?

While damage to the brain following a traumatic brain injury is permanent because damaged brain cells cannot regenerate or repair themselves, there is hope for functional recovery. This is because functions affected by TBI may be rewired and improved by healthy brain cells.

What happens to the brain after trauma?

The brain becomes somewhat disorganized and overwhelmed because of the trauma, while the body goes into a survival mode and shuts down the higher reasoning and language structures of the brain. The result of the metabolic shutdown is a profound imprinted stress response.

Can you live a normal life after brain injury?

While life after brain injury will not be easy, it is still possible to achieve happiness. Your life may look a lot different now, but it can still be worthwhile.

How is brain damage diagnosed?

A medical exam is the first step to diagnose a potential brain injury. Assessment usually includes a neurological exam. This exam evaluates thinking, motor function (movement), sensory function, coordination, eye movement, and reflexes. Imaging tests, including CT scans and MRI scans, cannot detect all TBIs.

What is primary brain injury?

Primary brain injury refers to the sudden and profound injury to the brain that is considered to be more or less complete at the time of impact. This happens at the time of the car accident, gunshot wound, or fall.

What is the term for a brain injury that occurs when there is no break in the skull?

Brain injury may happen in one of two ways: Closed brain injury. Closed brain injuries happen when there is a nonpenetrating injury to the brain with no break in the skull.

What causes a bruise on the side of the head?

When there is a direct blow to the head, the bruising of the brain and the damage to the internal tissue and blood vessels is due to a mechanism called coup-contrecoup. A bruise directly related to trauma at the site of impact is called a coup lesion (pronounced COO ). As the brain jolts backward, it can hit the skull on the opposite side and cause a bruise called a contrecoup lesion. The jarring of the brain against the sides of the skull can cause shearing (tearing) of the internal lining, tissues, and blood vessels leading to internal bleeding, bruising, or swelling of the brain.

What is a bruise on the opposite side of the skull called?

As the brain jolts backward, it can hit the skull on the opposite side and cause a bruise called a contrecoup lesion.

What is the term for the shearing of the brain's nerve fibers?

Diffuse axonal injury is the shearing (tearing) of the brain's long connecting nerve fibers (axons) that happens when the brain is injured as it shifts and rotates inside the bony skull. DAI usually causes coma and injury to many different parts of the brain.

What causes head injuries in children?

There are many causes of head injury in children and adults. The most common injuries are from motor vehicle accidents (where the person is either riding in the car or is struck as a pedestrian), violence, falls, or as a result of shaking a child (as seen in cases of child abuse).

When does rehabilitation begin for brain injury?

Rehabilitation of the patient with a brain injury begins during the acute treatment phase. As the patient's condition improves, a more extensive rehabilitation program is often begun. The success of rehabilitation depends on many variables, including the following:

What happens when you are triggered into a trauma state?

When you are triggered into a trauma state, you may not be able to connect with or utilize the strengths and resiliencies you can exercise in other contexts. The parts of your brain that help you assert yourself, calm down negative thinking, regulate emotions, make mindful choices, or realistically evaluate risk and reward may not have a strong enough connection to the "raw" trauma memory to be able to calm things down and redirect.

How does trauma affect you?

In the case of trauma, for example, your sense of a lack of safety or lack of self-worth may continue even when your current environment is not dangerous, and you are valued at your job or by your family and friends. It's as if the new information is not getting to the parts of your brain that store your trauma memory. When you suffer from post-traumatic stress, you are more likely to view current events through the lens of trauma, leading you to perceive things inaccurately and overreact or under-react. You can get stuck in fixed ways of thinking and feeling that are more reflective of the past than your present.

Why does trauma shut down other systems?

Because experiencing severe trauma can shut down other systems not involved in emergency responding, it is also likely that parts of your brain that are involved in enjoying the moment, celebrating your own successes, pursuing positive goals, relaxing, feeling gratitude or awe, or bonding securely with other people are underutilized.

What is the term for the neural network that is isolated from other parts of the brain and resistant to change?

Trauma creates fixed neural networks that are isolated from other parts of your brain and resistant to change.

Why is it so hard to access trauma?

Traumas Make Your Strengths and Coping Tools Harder to Access. Weaker connections between neurons in a brain network may make it harder for your brain to perform certain functions, such as concentrating on a task without interruption or inhibiting unhelpful thought patterns or destructive impulses.

How does post traumatic stress affect you?

When you suffer from post-traumatic stress, you are more likely to view current events through the lens of trauma, leading you to perceive things inaccurately and overreact or under-react. You can get stuck in fixed ways of thinking and feeling that are more reflective of the past than your present.

What happens to neurons after trauma?

As a result of trauma, certain groups of neurons (those related to survival functions) may, over time, connect more strongly with each other while becoming more isolated from the rest of the brain.

What are the two types of traumatic brain injuries?

Doctors typically group traumatic brain injuries into two main categories: closed injuries and open (or penetrating) injuries. Closed injuries refer to TBIs that do not fracture the skull. Open injuries, on the other hand, occur when the skull bone breaks or is penetrated, leaving the brain exposed to the elements.

How long does it take to recover from a traumatic brain injury?

Treatment for traumatic brain injury will depend on the type and severity of your injury. If the injury only caused mild bruising, you will be sent home to rest. After a few days, you can gradually return to your normal activities.

What determines the rehabilitation plan for a TBI?

The type of traumatic injury you experience will determine what your TBI rehabilitation plan might entail.

Why is it hard to detect a diffuse axonal injury on an MRI?

The axonal shearing disrupts messages that neurons send, resulting in loss of function. Because most diffuse axonal injuries result in only microscopic tears, they can be hard to detect on an MRI. The severity of symptoms in a diffuse axonal injury depends on how large the tears are and where they are located.

What happens when you hit a head with a TBI?

During the impact, the brain crashes back and forth within the skull resulting in bruising, bleeding, and the shearing of nerve fibers known as axons.

Trauma can be defined as a deeply distressing response to a real or perceived threat to one’s life. Trauma can result from events including, but not limited to, getting physically or sexually assaulted, sudden death of family members or close friends, ...

What is missing from trauma?

What’s often missing is a basic understanding of how trauma impacts the brain and how such function, in turn, affects behavior. Knowledge of the traumatized brain can drastically improve how we engage our young people in order to practice a trauma-informed approach.

What is the thalamus?

The thalamus sits atop of the brain stem and is responsible for processing external stimuli. Sounds, images, any of the senses are first sent through the Thalamus, or as I like to call it the “gatekeeper.” The thalamus is like a gatekeeper or bouncer at a club. They are the first to receive all the action; everything that wants to “get in.”

Which part of the brain is associated with memory?

Hippocampus. The hippocampus is also part of the limbic system and is associated with memory. When the amygdala is triggered into an alarm state (i.e., a threat is perceived and the smoke detector goes off) it also relies on past memory/experience (e.g., a past threatening experience that is again happening currently).

Which part of the brain sends a message to the brain to fight or flight?

Hypothalamus. When the amygdala and hippocampus work in tandem to declare threat, the hypothalamus quickly sends a message down the brain stem. This activates autonomic nervous system functions like increased or decreased heart palpitations, sweating, etc. and sends the body into fight, flight, or freeze states.

Which structure of the brain is responsible for language processing?

Finally is the forebrain, which includes the neocortex and is responsible for our higher order functions like language, abstract reasoning and of course executive function. The major structures of the brain involved in processing trauma are the thalamus, the amygdala, the hypothalamus, and the hippocampus.

What happens when you go through trauma?

When we go through trauma, our brains don’t function like they normally do. We shift into survival mode. Like a deer in the headlights, our brains direct all our mental and physical energy toward dealing with the immediate threat until it’s gone. In normal situations, this state fades over time.

Why is it so hard to overcome trauma?

Part of the reason it can be so hard to overcome the effects of trauma is that it goes after several areas of your brain at once. According to a 2006 study by NIH, trauma mainly affects three important parts of your brain: the amygdala, which is your emotional and instinctual center; the hippocampus, which controls memory;

How to reverse trauma?

During the healing process, you can actually rewire and retrain your brain to reverse the effects of trauma. You can reinforce your prefrontal cortex and get back rationality and control. You can strengthen your hippocampus and help your memory work how it’s supposed to. And you can subdue the hyperactive amygdala, which will help bring you peace.

How does trauma affect us?

Trauma can change the way we think, feel, and act for a long time after the initial event. For many people, this could mean flashbacks or nightmares, a constant feeling of being on edge, loneliness, anger, intrusive thoughts and memories, self-destructive actions, and more.

What is whole wellness therapy?

Our approach at Whole Wellness Therapy is based on this simple truth, that our brains physically change based on our surroundings. That means that the best therapeutic environment that we work to create at our offices, puts you in a growth producing environment. This philosophy is what makes us so successful in treating the complexity of past trauma with our unique trauma therapy.

What happens when you get traumatized?

Trauma can cause your brain to remain in a state of hypervigilance, suppressing your memory and impulse control and trapping you in a constant state of strong emotional reactivity.

Can trauma go away on its own?

All these things are very normal responses to trauma, but they don’t always go away on their own. The good news is that patterns that might seem permanent can actually be reversed--with the right approach and knowledge, you can shift your brain towards healing. However, it can be difficult to see a path forward without first understanding how and why these changes happen.

What part of the brain is affected by trauma?

According to neuroimaging studies, the main areas of the brain impacted by trauma are the amygdala, the hippocampus and the ventromedial prefrontal cortex. These are part of a stress circuit in the brain which may explain why traumatic stress continues long after the event is over. The changes in these parts of the brain may also be responsible for specific symptoms PTSD.

What are the effects of trauma on the brain?

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 person’s behavior can be reversed and minimized through regular treatment.

Why do we use neuroimaging?

Tools like neuroimaging are used to create maps of the brain in order to study PTSD sufferers. These maps show areas of the brain that vary from normal non-trauma brain structure. Traumatic stress leads to significant changes in brain structure and function that cause the victim to continue experiencing stress.

Why do PTSD patients lose volume?

PTSD victims lose volume in the hippocampus due to elevated stress hormones. As a result they may have trouble telling the difference between the past and present leading them to avoid situations that remind them of their trauma. Volume loss also takes place in the vmPFC which controls our response to emotions.

What is the insula of the brain?

Children with post-traumatic stress will have variations in the volume and surface area of the insula. The insula is a region of the brain buried deep in the cerebral cortex that is crucial for self-awareness ...

What happens when you have trauma?

When a person experiences trauma, a certain part of their brain takes over that triggers the “fight or flight” response meant to protect us from danger. In this mode, nonessential body and mind functions shut down until the threat ceases and the nervous system allows those higher functions to resume.

What is volume loss in PTSD?

Having volume loss in this area can make it harder for PTSD victims to control their reactions and behavior. They may also have an enlarged amygdala which causes them to have negative moods and further difficulty controlling emotions.
