Abstract : This work examine PTSD symptoms impact on cognition: attention, memory and executive functions to child, adolescent and adult. The first study, on attention, shows that child with sub-Clinical PTSD symptoms are characterized by attentional bias for negative and threat-Related stimuli. Adults have attentional impairment only for threat-Related information. Anxious symptoms leads to a generalization of attentional bias for child and adult. Inhibition, for PTSD child, present a deficit for threat-Related faces. This work shows that cognitive impairment on PTSD adolescents are irregular. During symptomatic phase, episodic memory, working memory and inhibition for threat-Related information are degraded. After therapy, cognitive impairment are more important: short-Term memory, working memory, episodic memory, treatment of information are distorted. Attentional bias for threat-Related stimuli and inhibition difficulties for anger and happy faces appear. Three month after, these impairment are not presented.Also, clinical and cognitive markers of chronic PTSD or relapse are found. Traumatic distress, residual symptoms, episodic memory or attentional impairment (attentional bias and inhibition) are identified as risk markers for PTSD. This work shows cognitive consequences of trauma in childhood and major function of co-Morbidity on these consequences.
