Trauma
Trauma is defined as exposure to actual or threatened death, serious injury, or sexual violence through direct experience, witnessing, or learning of such events happening to loved ones. Traumatic events are highly stressful by nature and typically incite intense feelings of horror, fear, lack of safety, or panic at the time of exposure.
Traumatic experiences alone do not inevitably lead to long-term traumatic effects or post-traumatic stress disorder (PTSD). Rather, trauma severity, as well as subjective interpretations, available social supports, and individual resilience levels, interact to determine psychological outcomes post-trauma.
Trauma severity factors like physical harm, perceived threat of death or harm, and intentional human perpetration make it more likely that the brain’s fear circuitry becomes over-sensitized, leading to lasting PTSD symptoms. The developmental stage at which trauma occurs also matters, with childhood trauma being particularly impactful on emotional processing pathways.
