Neuroimaging studies of non-suicidal self-injury in young adults with major depressive disorder.

In 30 seconds

This systematic review analyzed 24 neuroimaging studies involving 2379 young adults with major depressive disorder (MDD) to explore non-suicidal self-injury (NSSI). The review identified distinct neural signatures in nsMDD, including suppression of the frontal gyrus and reduced volume of the putamen, differentiating it from MDD without NSSI. The study adhered to PRISMA guidelines.

Key findings

• Distinct neural signatures in nsMDD include suppression of the frontal gyrus and reduced volume of the putamen.
• The default mode network shows enhanced connectivity with other neural networks in nsMDD.
• Abnormal activation was noted in the lingual gyrus and midline cortical structures in nsMDD.

Why it matters

Understanding the neurobiological underpinnings of non-suicidal self-injury in major depressive disorder can inform targeted interventions and improve treatment outcomes for affected individuals.

What to keep in mind

Limitations include cross-sectional designs, gender imbalance, and a lack of multimodal data.
