CTSS Neurobiological Impacts of Trauma 3

Question 1

The concept of 'allostatic load' in trauma research refers to:

Accepted Answer

The cumulative physiological wear and tear resulting from chronic stress exposure

Answer

Allostatic load describes the cumulative biological cost of chronic stress adaptation, including dysregulation of cortisol, inflammatory markers, and cardiovascular function, leading to increased disease risk in trauma survivors.

Question 2

Higher Adverse Childhood Experiences (ACEs) scores are most directly correlated with which neurobiological outcome?

Accepted Answer

Increased risk of chronic disease through persistent neurobiological dysregulation

Answer

The landmark ACE study and subsequent research demonstrate that higher ACE scores are dose-dependently associated with HPA axis dysregulation, inflammation, and significantly elevated risk for cardiovascular disease, cancer, and mental health disorders.

Question 3

Neuroplasticity is significant in trauma treatment because it refers to the brain's:

Accepted Answer

Ability to reorganize and form new neural connections in response to experience

Answer

Neuroplasticity — the brain's lifelong capacity to form new synaptic connections and reorganize — underpins the effectiveness of trauma therapies, demonstrating that trauma-related neural patterns can be modified through treatment.

Question 4

The default mode network (DMN) in trauma survivors frequently demonstrates abnormal activation patterns characterized by:

Accepted Answer

Overactivity during self-referential processing, contributing to rumination and intrusion

Answer

In PTSD, the DMN shows hyperactivation during self-referential processing, which is associated with increased rumination, intrusive thoughts, and difficulty disengaging from trauma-related self-narratives.

Question 5

Oxytocin's role in trauma recovery is most accurately described as:

Accepted Answer

Promoting social bonding and trust responses that support co-regulation and recovery

Answer

Oxytocin, the 'social bonding' neuropeptide, facilitates trust, attachment, and co-regulation — processes central to trauma recovery through safe therapeutic relationships and social support systems.
