Clinical findings showed that a single session of approx. 25 minute behavioural intervention (reminder cue + mental rotation instructions + Tetris game play) reduce intrusive memories of trauma over one week (Yiadurai, 2018, Horsch, 2017). Idealy it should be applied before the first night of sleep after the exposure. Longer term studies needed.


CBT for Acute Stress Disorder (ASD) or clinically significant levels of posttraumatic stress symptoms (Giumarra et al, 2018), early exposure-based cognitive intervention (Shalev et al, 2012), prolonged exposure for ASD (Bryant, 2008). There is no consensus whether or not CBT alter the trajectory in a favourable way. We do not recommend to do this, because it could be just the waste of resourses.
