Trauma changes the way the brain functions from "summary" of The Body Keeps the Score by Bessel A. Van der Kolk
Trauma can alter the way the brain processes information and responds to stimuli. The impact of trauma on the brain can be profound, leading to changes in how an individual perceives and interacts with the world around them. The brain is constantly adapting and changing in response to experiences, and trauma can disrupt this process, causing long-lasting effects on cognitive and emotional functioning. One way in which trauma affects the brain is by disrupting the normal functioning of the amygdala, the brain's fear center. When a person experiences trauma, the amygdala can become hypersensitive, leading to exaggerated fear responses and heightened levels of anxiety. This can result in a constant state of hypervigilance, where the individual is on high alert for potential threats, even in situations where there is no real danger present. In addition to affecting the amygdala, trauma can also impair the functioning of the prefrontal cortex, the part of the brain responsible for decision-making, problem-solving, and emotional regulation. When the prefrontal cortex is compromised by trauma, individuals may struggle with impulse control, have difficulty managing their emotions, and struggle to make sound judgments. This can lead to impulsive behavior, mood swings, and difficulties in forming and maintaining relationships. Furthermore, trauma can impact the hippocampus, a region of the brain involved in memory processing. Chronic stress and trauma can damage the hippocampus, leading to difficulties in forming new memories and recalling past experiences. This can result in fragmented memories of traumatic events, as well as difficulties in organizing and integrating information.- Trauma can have a profound impact on the way the brain functions, leading to a range of cognitive and emotional difficulties. By understanding how trauma affects the brain, we can better support individuals who have experienced trauma and help them heal and recover.
