Abstract:
Non-suicidal self-injury is common in adolescents. At present, the pathological mechanism of non-suicidal self-injury is still unclear, and there is a lack of objective biological markers in diagnosis and treatment, which is an urgent problem to be solved in clinical diagnosis and treatment. The magnetic resonance imaging is an important technique to explore the imaging mechanism of non-suicidal self-injury. The purpose of this review is to systematic evaluation of the latest research results of magnetic resonance imaging of non-suicidal self-injury. It was found that non-suicidal self-injury in people without other mental disorders showed abnormal damage in the orbitofrontal, the dorsolateral prefrontal lobe, the medial prefrontal lobe, the ventrolateral prefrontal lobe, the amygdala, the cingulate gyrus, the supramarginal gyrus, the amygdala, the hippocampus, the insular, the corpus callosum, the thalamus, the putamen, the dorsal striatum, the cuneate prefrontal lobe and the right temporal lobe. These areas are the core areas related to emotional processing, decision-making, cognition and movement. Non-suicidal self-injury with other mental disorders such as borderline personality disorder and depression may be affected by underlying diseases and exhibit different damage patterns, which showing abnormal brain regions related to emotional network, decision-making, social cognition and exercise.The results of this review can be helpful for the future study of the magnetic resonance imaging mechanism of non-suicidal self-injury.
