Neurobiological and genetic factors influencing the number of intrusive memories
trauma
We replicated previous findings [Further, a stronger cortisol and sAA response to the film paradigm was positively associated with intrusive memories suggesting that a heightened biological stress response is predictive of intrusive memories after a trauma analogue. This finding is consistent with previous studies showing a positive association between increased salivary cortisol levels and elevated noradrenergic activation and intrusive memories [
