Emotional memory processing in post-traumatic stress disorder affected Colombian youth.

Post-traumatic stress disorder (PTSD) is a neuropsychological condition caused by exposure to chronic stressors and extreme trauma. In past decades, Colombia (South America) has experienced high levels of armed conflict, which created an environment of chronic stress, resulting in an increased incidence of PTSD in children. Limited research exists on the effects of PTSD on emotional memory functioning of these Colombian youth living in chronically stressful environments.

Implicit processing of emotional words by children with Post-Traumatic Stress Disorder: An fMRI investigation.

Background/objective: In the last decade, socio-political violence in Colombia (South America) has created an environment of extreme/chronic stress. In this study, brain imaging technology (fMRI) and behavioral task performance were used to measure potential deficits in executive functioning for emotional processing in Colombian children.

Method: Participants (22 Post-Traumatic Stress Disorder, PTSD and 22 neurotypical, NT) were asked to perform a word task with implicit emotional salience, which required them to report the color of the ink in which a positive, negative or neutral word was printed.

Cognitive profiles of Post-traumatic Stress Disorder and depression in children and adolescents.

Several diagnostic criteria of Post-traumatic Stress Disorder (PTSD) are remarkably similar to symptoms reported by individuals with depression, particularly as they manifest as cognitive processing deficits in children. Because of this overlap in profile and the high rate of comorbidity of PTSD and depression (48% to 69%), pinpointing similarities/differences in cognitive processes related to each of these disorders is essential to accurate diagnosis. This study aims to examine cognitive performance profiles of 23 children who have been victims of PTSD and to compare their results with 23 children with depression and 24 controls.
