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.


Sleep deprivation – some benefit (Porcheret, 2015). Not benefitial in reduction of traumatic intrusions (Sopp, 2020). Data is contradictory (Porcheret, 2019). week: sleeping “too little” or “too much” was associated with more intrusive memories (Porcheret, 2020).
