NR3C1 and post-traumatic stress disorder: Despite the potential advantages of the above-proposed approaches in triggering (e.g. enhancing the stress response or increase glucocorticoid receptor sensitivity) and measuring dissociative behaviours (e.g. using the CADSS), the identification of brain correlates of dissociation in PTSD remains correlational in nature, with fMRI paradigms not designed to identify causal associations.
