Final answer:
Acute and post-traumatic stress disorder (PTSD) are both triggered by traumatic events, similar to dissociative disorders. They are not varieties of depression or most successfully treated with antipsychotics, and they were recognized before the DSM-5.
Step-by-step explanation:
Acute and post-traumatic stress disorder (PTSD) have one major commonality with dissociative disorders; they are triggered by traumatic events. Both disorders can stem from severe psychological trauma, such as exposure to military combat, physical assaults, natural disasters, and serious accidents. On the other hand, dissociative disorders can include symptoms like a disruption of and/or discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior.
It's important to note that PTSD and dissociative disorders are not varieties of depression, though they may co-occur with depressive symptoms. Furthermore, they are not most successfully treated with antipsychotics as a general rule; treatments can vary widely and may include psychotherapy and, in some cases, antidepressants or other medications. Lastly, both PTSD and dissociative disorders were recognized before the publication of DSM-5, with PTSD being identified in the DSM-III and dissociative disorders in earlier versions of the manual.
