reexperiences

Reexperiences, also referred to as re-experiencing, are episodes in which a person relives a past event as if it were happening in the present. This phenomenon is studied in trauma psychology and psychiatry, where it is a core feature of post-traumatic stress disorder (PTSD). Reexperiences can present as intrusive memories or flashbacks of a traumatic event, distressing dreams, and distress or physiological arousal when reminded of the event. They are characteristically involuntary, vivid, and may occur with a sense of current danger or dissociative experiences, distinguishing them from ordinary voluntary memory recall.

Neurobiologically, reexperiences are linked to heightened amygdala activity and altered connectivity with hippocampal and prefrontal regions, reflecting intensified emotional processing and challenges in contextualizing the memory. Individual factors such as the nature of the trauma, coping strategies, and co-occurring conditions like depression or anxiety influence their manifestation. Reexperiences can vary in intensity and duration and may be triggered by reminders, stress, or bahkan seemingly unrelated stimuli.

In clinical practice, reexperiences are evaluated within the framework of PTSD criteria, though they can occur in acute stress disorder and other trauma-related conditions. Treatment typically emphasizes trauma-focused therapies, including prolonged exposure, cognitive processing therapy, and eye movement desensitization and reprocessing (EMDR). Medications such as certain antidepressants may help with associated symptoms like hyperarousal. With evidence-based care, many individuals experience reductions in the frequency and severity of reexperiences, though recovery trajectories vary. In research, reexperiences contribute to understanding memory encoding, retrieval, and the sense of present relevance attached to past events.
