Neuro Anatomic Basis of Psychic Pain in Depression and Suicidal Behaviour
Abstract
Suicidal behaviour (SB) represents a major public health problem, costing life in more that one million people every year worldwide. Even if SB is considered as a consequence of social adversity and depression, these stress factors are often necessary but not sufficient to explain the occurrence of a suicidal act. A preliminary study suggests that an increased perception of psychic pain during a major depressive disorder increases the risk of suicide behaviour. The investigators aimed to investigate the relationship between social exclusion (a classic trigger of psychic pain) and SB and improve our knowledge about the physiopathology of this domain.
Conditions: Suicide, Attempted, Mood Disorder.
Primary outcome: Cerebral regions associated with psychic pain during a major depressive disorder; Cerebral regions associated with perception of social exclusion.
Enrollment: 123 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 123 participants or records.
