“…In addition, a traumatic event can lead to the emergence of intrusive memories, especially shortly after the trauma [30]. These memories can be distressing and interfere with daily functioning, although they often diminish over time [31][32][33][34] However, they can also serve adaptive purposes, such as warning signals or assisting autobiographical memory coherence [35,36]. Dealing with these memories is critical to trauma prevention and early intervention strategies.…”

Traumatic events, especially massive trauma resulting from catastrophic incidents, wars, or severe abuse can elicit significant neuropsychological alterations, with profound implications for cognitive, emotional, and behavioral functioning. This mini-review delineates the primary neural changes post-trauma and underscores the importance of timely neuropsychological and clinical interventions. Specific brain regions, including the amygdala and prefrontal cortex, undergo physiological changes that can lead to memory impairments, attention deficits, and emotional disturbances. PTSD, a commonly diagnosed condition post-trauma, exemplifies the intricate relationship between trauma and memory processing. Furthermore, the concept of neuroplasticity, the brain’s inherent ability to adapt and rewire, offers hope for recovery. Current clinical interventions, such as cognitive behavioral therapy, mindfulness practices, and biofeedback, leverage this neuroplastic potential to foster healing. The review underscores the vital importance of early intervention to mitigate long-term neuropsychological impacts, emphasizing the role of timely and targeted clinical interventions. The synthesis of this knowledge is crucial for clinicians, allowing for informed therapeutic approaches that holistically address both the physiological and psychological dimensions of trauma.

Background Intrusive memories of psychologically traumatic events bring distress both sub-clinically and clinically. This parallel-group, two-arm randomised controlled trial evaluated the effect of a brief behavioural intervention on reducing intrusive memories in frontline healthcare workers exposed to traumatic events during the COVID-19 pandemic. Methods Participants with at least two intrusive memories of work-related trauma in the week before recruitment were randomised 1:1 to an imagery-competing task intervention (n = 73) or attention-based control task (n = 71). The number of intrusive memories was assessed at baseline and 5 weeks after the guided session (primary endpoint). Results The intervention significantly reduced intrusive memory frequency compared with control [intervention Mdn = 1.0 (IQR = 0–3), control Mdn = 5.0 (IQR = 1–17); p < 0.0001, IRR = 0.30; 95% CI = 0.17–0.53] and led to fewer post-traumatic stress-related symptoms at 1, 3 and 6 month follow-ups (secondary endpoints). Participants and statisticians were blinded to allocation. Adverse events data were acquired throughout the trial, demonstrating safety. There was high adherence and low attrition. Conclusions This brief, single-symptom, repeatable digital intervention for subclinical-to-clinical samples after trauma allows scalability, taking a preventing-to-treating approach after trauma. Trial registration 2020–07-06, ClinicalTrials.gov identifier: NCT04460014.
