Neuroscience of Trauma

-

Trauma can have a profound impact on brain structures and functions. 



It often leads to changes in the prefrontal cortex, amygdala, and hippocampus. 



The prefrontal cortex, which is responsible for rational decision-making, can become underactive, leading to impulsive behavior. 



The amygdala, the brain’s alarm system, may become overactive, causing a heightened state of fear or anxiety. 


Additionally, the hippocampus, which plays a role in memory, can shrink, resulting in difficulties with learning and memory recall.

Trauma on the Brain: The Neurobiological Effects of PTSD | Daisy Payton | TEDxMeritAcademy


Video Summary: The neurobiological effects of PTSD can vary based on personal touch. PTSD is caused by extreme trauma and is seen most in women. Research shows that long term experience of traumatic stress has drastic impacts on specific structures of the brain, like the prefrontal cortex. These disruptions can affect the ability to regulate emotion, learn, and form new memories. It is treatable. Daisy attended the University of San Francisco and received her degree in Psychology and minor in Neuroscience. Currently, she runs her family’s ranch and cares for her hoard of animals. She’s applying to Psychology and Behavioral Neuroscience PhD programs this fall and plans to research genetics, neural basis of emotion, and psychopathology. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Introduction to Adolescent Brain Development

During adolescence, the brain undergoes a remarkable period of growth and change.  This phase is marked by the strengthening of neural connections and significant developments in regions like the prefrontal cortex, which is responsible for decision-making and impulse control.  At the same time, the brain’s reward system becomes more active, leading teens to seek new and exciting experiences.  This combination of developing impulse control and a heightened reward response helps explain why adolescents may engage in risk-taking behaviors or struggle with regulating their emotions.

Understanding Trauma

-
Image
Trauma can be defined as an emotional or psychological response to a deeply distressing or disturbing event.  For adolescents, trauma might result from various experiences such as bullying, neglect, family violence, or witnessing a traumatic event.  These experiences can disrupt a teenager’s sense of safety and well-being, leading to long-lasting emotional and physical consequences.  Trauma is particularly impactful during adolescence due to the ongoing development of the brain and the way teens process emotions. Check out this video! Childhood Trauma Video Summary:   The most important thing a parent can do for their child after a traumatic event is to ensure and provide safety. Allow them to make sense of their emotional reactions such as fear or grief. Sources: • American Psychological Association. (2020). Trauma. Retrieved from www.apa.org • van der Kolk, B. (2014).
