Post-Traumatic Stress Disorder (PTSD) is characterized not only by intrusive recollections of trauma but also by widespread disruptions in everyday memory and cognitive functioning. This paper examines how PTSD alters event processing, declarative memory, and the organization of ordinary experiences. A review of empirical literature indicates that individuals with PTSD exhibit heightened emotional and sensory re-experiencing of traumatic events alongside deficits in encoding and recalling neutral or contextual information. Research on the emotion-induced memory trade-off demonstrates that emotionally salient details are often preserved at the expense of surrounding context, contributing to fragmented and incoherent memory representations. Additionally, studies on event segmentation reveal impairments in organizing daily experiences into meaningful units, which mediates deficits in everyday memory performance. Evidence from developmental and twin research further suggests that both trauma-related cognitive changes and pre-existing memory vulnerabilities may contribute to PTSD symptomatology. Collectively, these findings support the conclusion that PTSD fundamentally disrupts the architecture of memory, impairing not only trauma recall but also the cognitive processes necessary for adaptive daily functioning. Clinical implications emphasize the importance of interventions that target both intrusive trauma memories and broader deficits in event processing to improve overall quality of life in trauma-exposed populations.
