Stress and Emotional Memory (SEME)
Stress and Emotional Memory : Functional Neuroanatomy of Post-traumatic Stress Disorder in Adolescents
A broad group of disorders is associated with severe stress existence in children or adolescents. The most characteristic result, and one of the most serious being the state of post-traumatic stress disorder (PTSD), whose main source consists of physical or sexual violence, and to a lesser extent, accidents public road or natural disaster, whose child was the subject or witness. PTSD is associated with a deleterious effect on cognition and including the mnemonic operation. The painful reminder of the traumatic event is one of the most disabling symptoms. However, there are many other memory disorders that experimental studies gradually update. They maintain a close link with emotional regulation that disturbed you know if PTSD. However the majority of studies on emotion and cognition and their relationship with brain activity took adult subject. Work in adolescents are few on the morphological study, on rare neurobehavioral and reduced to two studies of functional neuroimaging. Contrary to what is observed in adults, morphological studies report consistently, no reduction in hippocampal volume. There is no study in the idle state. Two studies in functional MRI, the first highlighted in PTSD patients inhibition of the activity of the anterior cingulate cortex (ACC) to stimuli such as to evoke the trauma, a second reported increased activity in the prefrontal cortex Median (mPFC) in a inhibition. The objective task of our study is to evaluate the impact of psychological trauma on brain structures involved in the emotional component of the memory (amygdala, hippocampus, prefrontal cortex in particular). For this, the investigators will take in 33 adolescents, including patients with posttraumatic symptomatology and matched controls free of trauma age, several neuroimaging exams, anatomical and functional. The functional review will include some rest and another in activation during episodic memory task designed to assess the influence of self-perception on memory impairment observed in patients. The investigators will check, for each group of patients and controls, the involvement of cortical structures in relation to the regulation of emotional memory (CCA, amygdala and hippocampus). The anatomy of the hippocampus benefit specific imaging methods developed in the unit INSERM U923. Endocrine correlates of stress tests will be studied by a fully-traumatic by salivary cortisol sampling.
This research will clarify the mechanisms involved in emotional and memory impairments secondary to psychological trauma, their relationship with self (judgment and self-esteem) and studying their morphological substrates. A longer-term goal is to offer help in the diagnosis and monitoring of young patients with posttraumatic symptomatology.
