Core Tip

Core Tip: This study investigates structural network communication differences in depressed adolescents, highlighting impaired brain network efficiency in those with non-suicidal self-injury and suicide attempts. Using diffusion magnetic resonance imaging, the research identifies disrupted cortico-cortical and cortico-subcortical circuits, particularly in regions such as the posterior cingulate gyrus and nucleus accumbens. The findings suggest that compromised neural communication is linked to clinical symptoms, offering new insights into the neurobiological mechanisms behind the comorbidity of non-suicidal self-injury and suicide attempts in depression.
