Summary: | Abnormal salience attribution is implicated in heroin addiction. Previously, combining functional magnetic resonance imaging (fMRI) and a drug cue‐reactivity task, we demonstrated abnormal patterns of subjective response and brain reactivity in heroin‐dependent individuals. However, whether the changes in cue‐induced brain response were related to relapse was unknown. In a prospective study, we recruited 49 heroin‐dependent patients under methadone maintenance treatment, a gold standard treatment (average daily dose 41.8 ± 16.0 mg), and 20 healthy subjects to perform the heroin cue‐reactivity task during fMRI. The patients' subjective craving was evaluated. They participated in a follow‐up assessment for 3 months, during which heroin use was assessed and relapse was confirmed by self‐reported relapse or urine toxicology. Differences between relapsers and non‐relapsers were analyzed with respect to the results from heroin‐cue responses. Compared with healthy subjects, relapsers and non‐relapsers commonly demonstrated significantly increased brain responses during the processing of heroin cues in the mesolimbic system, prefrontal regions and visuospatial‐attention regions. However, compared with non‐relapsers, relapsers demonstrated significantly greater cue‐induced craving and the brain response mainly in the bilateral nucleus accumbens/subcallosal cortex and cerebellum. Although the cue‐induced heroin craving was low in absolute measures, the change in craving positively correlated with the activation of the nucleus accumbens/subcallosal cortex among the patients. These findings suggest that in treatment‐seeking heroin‐dependent individuals, greater cue‐induced craving and greater specific regional activations might be related to reward/craving and memory retrieval processes. These responses may predict relapse and represent important targets for the development of new treatment for heroin addiction.
Whether abnormal salience attribution is related to relapse to heroin use was unknown. In a 3‐month follow‐up prospective cue response fMRI study, we found that compared with nonrelapsers, relapsers demonstrated significantly greater cue‐induced craving and the brain response mainly in the bilateral nucleus accumbens/subcallosal cortex and cerebellum. These findings suggest that, greater cue‐induced craving and activations in reward/craving and memory retrieval related regions may predict relapse and represent important targets for the development of new treatment for heroin addiction. |
