Question

What are some long-term effects of trauma on the brain?

Answer

Long-term trauma can significantly impact various brain regions, including the amygdala, hippocampus, and prefrontal cortex. The amygdala, responsible for emotional responses, can become hyperactive, leading to exaggerated fear responses, such as constant feelings of imminent danger.

Trauma survivors, especially those with childhood trauma, may exhibit smaller hippocampal regions, affecting memory, emotional regulation, and stress responses.  Additionally, trauma can suppress the prefrontal cortex, impairing executive functions such as decision-making, planning, and impulse control, potentially leading to issues like addiction, ADHD, or learning difficulties.

  'The instructor is very knowledgeable and is interesting in presenting new information on PTSD'   Read Reviews
This introductory course is designed to empower clinicians to more effectively identify the traumatic experiences that may be informing their client’s presenting concerns and to holistically conceptualize the impact those experiences may have had on their functioning. Towards those ends, it will introduce viewers to the current and historical sociopolitical contexts in which trauma and PTSD are understood, the range of experiences that may elicit an acute and/or posttraumatic response that go beyond “criterion A” events, the unique and shared symptoms presentations that may arise in vivo, the array of intra-and-interpersonal factors that both influence and protect against them, as well as the toll these experiences can have on an individual and their communities across the lifespan. The impetus for action laden within the material presented during this course, informed by the understanding viewers will develop regarding the now indisputable, holistic impact of trauma on the individual and our society, will function to highlight the need for interdisciplinary collaboration across the helping and medical professions to prevent and treat the consequences of trauma.
