Meta-Analysis Links CSTC Dysfunction to Substance Abuse Impulsivity

Summary

Story summary

Xiaonan Zhang in China published a meta-analysis of brain-connectivity abnormalities in substance-use disorder.
It pooled 53 rs-fMRI studies of 1,700 SUD participants (39 y, 19% women) and 1,792 controls (38 y, 30% women), revealing CSTC circuit dysfunction.
Findings showed the prefrontal cortex had stronger attention and weaker inferior frontal connections, the striatum over-connected to superior frontal gyrus and under-connected to median cingulate—a pattern linked to impulsivity—and authors propose brain-stimulation therapy guidance.
