Perception of Stressful Social Stimuli After Trauma Exposure.

Status Completed

Clinical Trial Summary

Post-traumatic stress disorder is associated with altered processing of sensory stimuli. The clinical phenotype PTSD has predominantly been described for the visual and auditory sensory modalities. However, PTSD symptoms such as intrusive memories are often evoked by olfactory and tactile cues in the environment. Moreover, little is known about whether aberrant responses to social olfactory and tactile stimuli are also present in a subclinical population.The purpose of this study is to compare trauma-exposed subjects (e.g. childhood maltreatment) with non-exposed controls in the processing of olfactory and tactile stimuli. This sensory characterizations hold potential to identify potential biomarkers for the course of trauma-related disorders and to inform trauma therapies focusing on sensory integration.
