how trauma affects the brain

Brain damage occurs when a person’s brain is injured due to traumatic injury, such as a fall or car accident, or nontraumatic injury, such as a stroke. Exposure to complex trauma in early childhood leads to structural and functional brain changes. Traumatic stress is associated with increased cortisol and norepinephrine responses to subsequent stressors. Under traumatic stress, the `lower’ brain stem responses predominate, and impair a person’s ability to be calm, learn, think, reflect and respond flexibly. %PDF-1.5 If there is not, then it allows access to the neocortex.

However, for those 20 percent of trauma survivors who go on to develop symptoms of post-traumatic stress disorder (PTSD) — an unmitigated experience of anxiety related to the past trauma — the shift from reactive to responsive mode never occurs. In other situations the changes evolve into readily apparent symptoms that impair function and present in ways that interfere with jobs, friendships and relationships.

With severe trauma however, after effects of this process remain which can lead to nightmares, flashbacks, and difficulty with change or self-expression. The Triune Brain model, introduced by physician and neuroscientist Paul D. MacLean, explains the brain in three parts: During a traumatic experience, the reptilian brain takes control, shifting the body into reactive mode. The impact of these changes are especially exacerbated by three major brain function dysregulations: While changes to the brain can seem, on the surface, disastrous and representative of permanent damage, the truth is that all of these alterations can be reversed. The four categories of PTSD symptoms include: intrusive thoughts (unwanted memories); mood alterations (shame, blame, persistent negativity); hypervigilance (exaggerated startle response); and avoidance (of all sensory and emotional trauma-related material).
