Feder et al. (2020) suggest that ketamine could be a potentially effective treatment for PTSD. Abdallah et al. (2022) did not find evidence to indicate that ketamine is an effective method for reducing PTSD symptoms, however, and suggest that further research needs to be done on this topic.
Trauma Informed Guilt Reduction (TrIGR) is a new form of talk therapy that lasts for about six sessions. Norman et al. (2022) indicate that this new intervention may be useful for individuals who experience notable levels of guilt after a trauma. It is currently under further study.
Jiang et al. (2021) studied how machine learning, which is a form of computational statistics, can identify specific traits associated with the onset of PTSD and whether the diagnostic process can be shortened without affecting its precision. Ultimately, it was concluded that machine learning is a promising potential strategy.
