How PTSD Affects Brain?

How PTSD affects brain?

After experiencing or witnessing traumatic events, several chemical and biological imbalances may present. There are three major brain function dysregulations that can be triggered or even exacerbated by PTSD:

  • Overstimulated amygdala: Amygdala is responsible for threat identification and tagging memories with emotion. Traumatic events can put amygdala in a highly alert state, thus perceiving threat everywhere.
  • Ineffective variability: The sympathetic nervous system in the brain remains highly activated after traumas, leading to fatigue, and affecting the system of adrenal.
  • Underactive hippocampus: The stress hormone glucocorticoid appears after traumatic events kills cells in the hippocampus, which makes it difficult for memory consolidation.
