Autobiographical Memory for Stressful Events, Traumatic Memory and Posttraumatic Stress Disorder: A Systematic Review

Abstract

Stressors and traumatic events may contribute in the development of many psychopathologies, especially Post Traumatic Stress Disorder (PTSD. People with this disorder can present significant memory loss, particularly in Autobiographical Memory (AM). This paper aims to present a systematic review of the literature regarding the changes in the Autobiographical Memory in people exposed to potentially traumatic stressors. Therefore a research in the databases PsycINFO, PubMed, Web of Science and Pilots was performed during March 2012. A total of 29 articles were selected. Results demonstrate that people with PTSD present alterations in a larger number of AM components compared to the cases where PTSD did not develop the disorder. In the same way, subjects who were never exposed to trauma did not demonstrate significant AM alterations when compared to the other groups. The results indicate that the changes in AM are primarily associated with PTSD, yet it was not possible to clarify whether such changes are related to the timely development of the disorder or if they are also observed in traumatic memories even in the absence of the disorder.

Transtorno Obsessivo-Compulsivo: Aspectos Genéticos E O Tratamento Com Base Na Terapia Cognitivo-Comportamental

“…A partir da visão de autores abordados, o TEPT resulta no prejuízo do funcionamento cognitivo, entre esses agravantes, cita-se a perca de memória autobiográfica, além da recuperação instantânea de memórias traumáticas, podendo provocar tentativas de suicídio, prejuízos na atenção e nas funções executivas, incluindo resoluções de problemas do cotidiano do indivíduo. Outro efeito seria o aumento ao risco de comportamento suicida, sendo tal ideia confirmada por um dos autores que desenvolveu uma pesquisa na comunidade, onde os pacientes com o transtorno tinham 14,9 vezes mais probabilidade de tentar suicídio de que indivíduos sem TEPT (KRISTENSEN;PARENTE;KASZNIAK, 2006;LORENZZONI et al, 2014).…”

Priming perceptivo y percepción de amenaza en exposición a eventos traumáticos: un estudio exploratorio

“…Por lo tanto, en futuros estudios, además de contemplar estas limitaciones, se requerirá incluir muestras traumatizadas, tal como en el estudio de Reyes et al, 2019. Los estudios en priming y recuerdos autobiográficos contemplan una comparación de grupos traumatizados con y sin tept a los cuales es relevante incorporar grupos sin exposición (Longhi Lorenzzoni et al, 2014). Esto implicaría la necesidad que se incluya una medida fiable para evaluar exposición a eventos altamente estresantes o tept en población hispano-hablante, que considere las dimensiones planteadas para el estrés (Berger, 2015;Dohrenwend, 2010) y los cambios en el diagnóstico en el dsm-5.…”

Psycholinguistic Markers of Autobiographical and Traumatic Memory

“…Another much debated question is whether stressful traumatic events and negative emotional life events could be identified (Berntsen et al, 2011;Lorenzzoni, Silva, Poletto, & Kristensen, 2014). There is a relatively small body of literature which concerns the difference between traumatic memories (stressful traumatic events) and non-traumatic experience (positive emotional events, neutral events, and negative emotional events) (Sotgiu & Rusconi, 2014).…”

“…The discrepancy of frequency might characterize the different storage and retrieval of information related to these events. While there have been extensive investigations of PTSD symptoms and treatment, little is known about how the autobiographical and traumatic memories are arranged and organized; and what are the mechanisms of transforming traumatic memory into PTSD (Lorenzzoni et al, 2014).…”
