There is a lack of safe, effective, fast and convenient clinical treatments. The enhancement of memory and the weakening of memory fading are the main reasons for the occurrence of PTSD, so for the prevention and treatment of PTSD, interventions targeting different stages of memory formation may be effective. Ketamine, as an N-methyl-D-aspartate receptor antagonist with good anxiolytic and antidepressant effects, is expected to be a new therapeutic drug for PTSD. In this paper, we will review the effects of ketamine on different stages of memory formation to provide new research ideas and directions for the prevention and treatment of PTSD.展开更多
