Expression of Trauma: Survival Circuit and PTSD
Trauma changes the way brain cells connect to each other. In post-traumatic stress disorder (PTSD), the survival circuit becomes overreactive and sensitive to anything that might seem like a threat.
-
- The parts of the brain involved in fear production become overactive.
- The parts of the brain that control fear, calm us down, and help us learn to overcome anxiety all get suppressed.
- The alarm signals from the brain may stay active, even when the threat is no longer present.
- The survival circuit may activate due to memories or reminders of memories. This includes objects and other things in the environment that do not actually pose a threat.
- When the person comes across these reminders or memories, they may have strong reactions and behaviors that don’t seem to fit the current situation.
Trauma can impact a person’s attention, memory (both short-term and long-term), and how they process information. The brain changes the way a person sees, experiences, and understands the world. These changes in the brain typically result in new behaviors, which are often labeled as symptoms. These symptoms can lead to a variety of problems and diagnoses. Many professionals frequently focus on the symptoms and overlook the person’s trauma experience.
