What happens to the brain during trauma?

• A. It releases stress hormones.
• B. It stops releasing hormones.
• C. It becomes immune to stress.
• D. It immediately heals.

Answer: (A)

During trauma, the brain kicks into its stress response. The hypothalamus signals the pituitary to release hormones that activate the adrenal glands, flooding the body with stress chemicals like adrenaline (and noradrenaline) and cortisol. This causes rapid heartbeat, faster breathing, heightened alertness, dilated pupils, and a surge of energy, all aimed at preparing the body to either fight or flee. At the same time, these hormones help the brain encode the traumatic experience more vividly, especially through the amygdala and hippocampus, which can lead to intense, lingering memories.

In a corrections context, this means a person may appear hyperaroused, easily startled, or dissociated during or after a traumatic event. Recognizing that these reactions are natural physiological responses helps staff respond with calm, controlled communication and de-escalation. The other options—stopping hormone release, becoming immune to stress, or healing instantly—do not reflect how the brain responds to trauma; the body continues to release stress hormones and healing is a gradual process, not immediate.
