Traumas like physical and emotional trauma often lead to PTSD which on average, affects roughly 8% of Americans. PTSD can typically be a lifelong problem for most people, resulting in severe brain damage.
Exposure to trauma can be life-changing—and researchers are learning more about how traumatic events may physically change our brains. But these changes are not happening because of physical injury; rather, the brain appears to rewire itself after these experiences.
The mechanism of emotional TBI includes the intricate actions of stress hormones on diverse brain functions due to changes in synaptic plasticity, where chronically elevated hormone levels reduce neurogenesis, resulting in dendritic atrophy and impaired cognition.
Trauma symptoms typically last from a few days to a few months, gradually fading as you process the unsettling event.
Delayed responses to trauma can include persistent fatigue, sleep disorders, nightmares, fear of recurrence, anxiety focused on flashbacks, depression, and avoidance of emotions, sensations, or activities that are associated with the trauma, even remotely.
There are absolutely health impacts from unresolved trauma. Unresolved trauma puts people at increased risk for mental health diagnoses, which run the gamut of anxiety, depression and PTSD. There are physical manifestations as well, such as cardiovascular problems like high blood pressure, stroke or heart attacks.
If the trauma is left untreated, one can experience nightmares, insomnia, anxiety, depression, phobias, substance abuse, panic attacks, anger, irritability, or hopelessness. The individual might also begin to have physical symptoms such as gastrointestinal distress, rapid heartbeat, or extreme fatigue.
Can the brain heal after being injured? Most studies suggest that once brain cells are destroyed or damaged, for the most part, they do not regenerate. However, recovery after brain injury can take place, especially in younger people, as, in some cases, other areas of the brain make up for the injured tissue.
van der Kolk writes that there are three avenues for recovery: “top down, by talking, (re-) connecting with others, and allowing ourselves to know and understand what is going on with us”; “taking medicines that shut down inappropriate alarm reactions"; and “bottom up, by allowing the body to have experiences that ...
Symptoms of negative changes in thinking and mood may include: Negative thoughts about yourself, other people or the world. Hopelessness about the future. Memory problems, including not remembering important aspects of the traumatic event.
Trauma is not physically held in the muscles or bones — instead, the need to protect oneself from perceived threats is stored in the memory and emotional centers of the brain, such as the hippocampus and amygdala. This activates the body whenever a situation reminds the person of the traumatic event(s).
Emotional Trauma Symptoms
Psychological Concerns: Anxiety and panic attacks, fear, anger, irritability, obsessions and compulsions, shock and disbelief, emotional numbing and detachment, depression, shame and guilt (especially if the person dealing with the trauma survived while others didn't)
Just like a physical scar from a deep cut takes time to heal, recovery from trauma is possible with time and treatment. It's important to remember that ignoring or avoiding symptoms of trauma isn't a healthy coping response (in fact, avoiding them can make things worse — more on that later).
What these activations indicate is that, often, a traumatized brain is "bottom-heavy," meaning that activations of lower, more primitive areas, including the fear center, are high, while higher areas of the brain (also known as cortical areas) are underactivated.
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.
The Hippocampus, responsible for short-term memories, shrinks. The Hippocampus helps us distinguish between past and present memories.
Emotional abuse is linked to thinning of certain areas of the brain that help you manage emotions and be self-aware — especially the prefrontal cortex and temporal lobe. Epigenetic changes and depression. Research from 2018 has connected childhood abuse to epigenetic brain changes that may cause depression.
Pharmacological (e.g., antidepressant medications) and nonpharmacological interventions (cognitive-behavioral therapy, exercise) may reverse stress-induced damage in the brain.
Will brain damage show up on an MRI? It's a question we get asked often by our clients who've suffered brain injuries. And the answer is if it's moderate or severe, most of the time it will show up on an MRI. If it's a mild brain injury, often it will not show up on an MRI.
Regaining a sense of safety may take days to weeks with acutely traumatized individuals or months to years with individuals who have experienced ongoing/chronic abuse.
A feeling of shame; an innate feeling that they are bad, worthless, or without importance. Suffering from chronic or ongoing depression. Practicing avoidance of people, places, or things that may be related to the traumatic event; this also can include an avoidance of unpleasant emotions.
