Purpose Of ReviewThe definition of psychological pain is complex. It is a lasting unpleasant and unsustainable feeling characterized by a perception of inability or deficiency of the self, as well as frustrated psychological needs and social disconnection. The aim of our review was to summarize the most recent and updated findings supporting the role of psychological pain in the pathophysiology of depression and suicidal behavior. We also explored the relationship between psychological and physical pain in depression and suicide.Recent FindingsPsychological pain is a prominent dimension of depressive disorder and has been associated with higher risk of suicidal ideation and suicidal behavior. Sensitivity to psychological and physical pain is increased in depression. Conversely, higher tolerance to physical pain is associated with suicidal behavior. A better understanding of the pathophysiology of pain processing in depression and suicide offers new therapeutic options for the treatment of depression through the use of analgesic drugs.
