In psychology, trauma is an emotional response to a distressing event or situation that overwhelms an individual's capacity to cope. It shatters a person's sense of safety, leaving them feeling helpless. While the word literally means “wound,” psychological trauma fundamentally disrupts how the brain processes fear, threat, and stress.
American Psychological Association (APA)
Any disturbing experience resulting in significant fear, helplessness, or dissociation that has a long-lasting negative effect on a person's functioning. It challenges an individual's view of the world as a safe, just, and predictable place.
Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
Clinically, a traumatic event often involves direct or indirect exposure to actual or threatened death, serious injury, or sexual violence.
Substance Abuse and Mental Health Services Administration (SAMHSA)
Events or circumstances experienced as physically or emotionally harmful or life-threatening that have lasting adverse effects on an individual's mental, physical, social, emotional, or spiritual well-being.
In the immediate aftermath of a trauma, the brain's threat-detection center, the amygdala, activates the fight, flight, or freeze response. Most people process these events and heal naturally with support. Some continue to suffer debilitating conditions, such as PTSD, long after the event has passed.
Trauma responses are not character flaws or signs of weakness. They are the nervous system's learned response to an experience that felt threatening or overwhelming. Once learned, the response can activate automatically, triggered by situations, sensations, or memories that remind the subconscious of the original event.
