Answer

The maximum duration a trauma memory can be suppressed

Answer

The period after trauma when cortisol returns to baseline

Answer

The time limit for effective EMDR sessions

Question 2

What is hyperarousal in the context of trauma neurobiology?

Accepted Answer

An elevated state of nervous system activation marked by anxiety, irritability, or hypervigilance

Answer

A state of emotional numbness and dissociation

Answer

Normal baseline nervous system functioning

Answer

Increased parasympathetic activity

Question 3

For a CDT practitioner, why is understanding polyvagal theory important when working with trauma survivors with disabilities?

Accepted Answer

It explains how the vagus nerve regulates social engagement and safety responses

Answer

It describes how medication manages cortisol levels

Answer

It outlines the role of genetics in disability

Answer

It details the biochemistry of serotonin reuptake

Question 4

What does the term 'allostatic load' refer to in trauma neurobiology?

Accepted Answer

The cumulative physiological wear and tear from chronic stress and trauma

Answer

The brain's capacity for new memory formation

Answer

The body's immune response to physical injury

Answer

It demonstrates that early trauma has lasting neurobiological and health consequences

Answer

It shows that trauma only affects adults

Answer

It proves that disability prevents trauma recovery
