Trauma Memory

Traumatic Stress Vulnerability

PTSD has its own characteristic genetic predisposition and unique biological composite. Individuals with PTSD apparently share genetic markers that are predictive for the cluster of symptoms that characterize PTSD. There seems to be a role for the dopamine D2 receptor gene, DRD2 A1+ allele. This gene has been associated with reduced D2 mesolimbic dopamine receptor binding and increased somatic concerns, anxiety or insomnia, social dysfunction and harm avoidance, and depression.

Traumatic Memory

Cumulative developmental trauma (emotional pain experienced in response to breached expectation from ontogenetically social motivational need fulfillment) and both early and later experienced trauma disrupts memory processing and sometimes produces post-traumatic stress disordered (PTSD) symptom expression in the genetically predisposed individual with genetically predisposed vulnerability for later developing the condition. Individuals who go onto to develop PTSD symptom expression typically seek trauma avoidance coping mechanisms due to the perceived intensity of emotional pain experienced with trauma retrieval.

Traumatic Recall in PTSD

Trauma survivors, who go on to develop later PTSD symptoms, throughout the post-trauma period, tend to develop narratives that avoid 1.) peripheral details of the most horrifying painful aspects of the trauma and 2.) perceptions of self in interaction experienced during and after the trauma. Their narratives often lack coherence, accurate chronological sequencing, and personal meaning. Their trauma narratives include the use of short and brief sentences, unfinished thoughts, and reliance on speech fillers and repetitions. (Read more)

Trauma Narratives in PTSD

A personal narrative is a sensory and spatial autobiographical map (of time, place, and event) to which personal meaning via emotion and emotionally- laden cognition of self in interaction has been cumulatively attributed. A traumatic experience normally disrupts autobiographical memory’s processing and development as well as the social connections mediating its development (Wigren, 1994). Trauma survivors’ early development of trauma narratives are individualized and unpredictable. (Read more)
