Sample interview questions: Can you describe your knowledge and experience regarding the impact of trauma on brain development?
Sample answer:
Knowledge and Experience Regarding the Impact of Trauma on Brain Development
Trauma has a profound impact on brain development, particularly during childhood. When a child experiences trauma, it can lead to lasting changes in the structure and function of their brain.
Structural Changes:
- Reduced hippocampus volume: The hippocampus plays a crucial role in memory formation and learning. Trauma can lead to a reduction in the size of the hippocampus, impairing these cognitive functions.
- Amygdala enlargement: The amygdala is responsible for processing fear and anxiety. Trauma can cause an enlargement of the amygdala, leading to heightened sensitivity to threat and an increased risk of developing anxiety disorders.
Functional Changes:
- Altered connectivity: Trauma can disrupt the connectivity between brain regions involved in emotion regulation, memory, and cognitive control.
- Neuronal pruning deficit: During adolescence, the brain experiences a process called pruning, where weaker neuronal connections are removed to strengthen remaining ones. Trauma can impair this pruning process, leading to an overabundance of weak connections and reduced brain efficiency.
