Dysfunction of neural circuitry in depressive patients with suicidal behaviors: A review of structural and functional neuroimaging studies

Abstract

Suicide is an important public problem. Understanding the neurobiological mechanisms of suicidal behavior in depression will facilitate the development of more effective prevention strategies for suicide. There are several reviews of imaging studies of suicidal behavior, but none of these reviews have focused only on suicide in depression. We reviewed neuroimaging studies of suicide in depression in recent years. The majority of studies found structural and functional alterations in the orbital frontal cortex, anterior cingulate cortex and striatum in depressive patients with suicidal behaviors. The evidence suggests that the frontal-striatal circuitry, which includes the striatum, orbital frontal and anterior cingulate cortices, is involved in the neurobiology of suicide in depressive patients. These findings also indicate that not all suicides have the same underlying neuropathology. Future studies require larger samples and more accurate subtypes of suicide. Furthermore, combining neuroimaging and other new technologies in molecular biology will be helpful to reveal the pathogenesis of suicidal behavior in depression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
