“…Las glándulas suprarrenales secretan a su vez hormonas corticoides como el cortisol o la aldosterona, que participan en toda una serie de cambios fisiológicos relacionados con la respuesta de estrés, como el metabolismo de los hidratos de carbono, el catabolismo de proteínas, e inciden sobre el sistema inmunológico alterando la producción de anticuerpos. Este eje es un claro ejemplo de la influencia recíproca entre sistema nervioso, sistema endocrino y sistema inmunológico (Seijas Gómez, 2013).…”

OBJETIVO: describir la neurofisiopatología del estrés postraumático METODO: construcción teórica con base a revisión bibliográfica y reflexiones RESULTADOS: el trastorno de estrés postraumático (TEPT) es una enfermedad mental y se manifiesta con tensión o estado de alerta. Puede desarrollarse luego de la exposición a un estresor el cual infiere en el comportamiento generando principalmente una respuesta defensiva, este es un punto de partida para la comprensión de un comportamiento. Los factores de vulnerabilidad son, los traumas en la infancia, experiencias violentas, accidentes de tránsito, fenómenos naturales, afecciones físicas y actualmente la pandemia por COVID-19. El trauma no solo provoca efectos mentales, sino que también provoca una especie de reset o recalibración del sistema nervioso. CONCLUSIÓN: un acontecimiento traumático hace que el cerebro cambie, produciendo una activación del sistema de alarma, se genera una reducción del volumen del hipocampo y en el eje Hipotálamo-Hipofisario-Adrenal también se produce una alteración en su funcionamiento; la interacción recíproca entre estos tres órganos genera las reacciones propias de la respuesta de estrés.

Neuropsychological and Physiological Outcomes Pre- and Post-EMDR Therapy for a Woman With PTSD: A Case Study

2015

This article provides a comprehensive review of the literature on the neurocognitive impact of posttraumatic stress disorder (PTSD) and reports on a quantitative single-case study, which investigated whether eye movement desensitization and reprocessing (EMDR) therapy would change the neuropsychological and physiological responses of an 18-year-old female client diagnosed with comorbid PTSD and major depressive disorder. Eleven 90-minute weekly sessions of EMDR therapy were provided. We used biofeedback equipment (ProComp5 Infiniti System) to obtain records of heart rate and conductance while the participant was in the desensitization and reprocessing phases of EMDR therapy. Results showed a heart rate decrease between baselines at the beginning and end of treatment. Neuropsychological evaluations of attention, memory, and brain executive functions showed pretreatment impairments in attentional processes, information processing speed, and working memory and posttreatment improvement of these cognitive functions, with significant differences on the Paced Auditory Serial Addition Test. We found a substantial posttreatment decrease in mean scores on the Beck Depression Inventory-II and the Dissociative Experiences Scale. Furthermore, the patient showed no signs of PTSD after the intervention, based on the Posttraumatic Stress Global Scale. At 1-year follow-up, the participant reported maintenance of treatment effects. We discuss how amelioration of PTSD symptoms was associated with improved neurocognitive outcomes.

The current case study investigates whether successful psychotherapy for posttraumatic stress disorder (PTSD) symptoms will also ameliorate cognitive deficits. We describe the treatment response of a 37-year-old woman diagnosed with post-traumatic stress disorder who received eight weeklyEMDR sessions. At pre-treatment, the patient reported emotional disturbance on the Beck Depression Inventory-II, and problems with anxiety and sleep. Testing showed high scores on the State-Trait Anxiety Inventory (STAI) and the Symptoms Scale of Post-traumatic Stress Disorder Scale-Revised (EGS-R). An evaluation of her attention profile and other executive functions was conducted with dual execution tasks using a virtual reality program, Nesplora Aquarium. The attention testing data indicated attention-deficit disorder (ADD). At the end of the therapy, testing showed improvements in sleep problems and in emotional disturbance and anxiety symptoms on all measures. The attention testing revealed normal scores for her age range in the Nesplora Aquarium test. A follow-up assessment was carried out at 1 month, and it was observed that the patient maintained the improvement achieved. We discuss the relationship between PTSD and cognitive impairment and the value of the Nesplora Aquarium test for cognitive assessments. Our results suggest attentional deficits in this case when performing a continuous execution test with dual execution components that involve the participation of the central executive system of working memory.
