To investigate the relationship between methadone maintenance treatment (MMT), sleep disturbances, and cortical thickness in patients with opioid use disorder, focusing on neurobiological implications.
Key Findings:
Increased cortical thickness in MMTS patients in the left entorhinal cortex, right pericalcarine cortex, and left frontalpole cortex compared to MMT patients (all p < 0.05).
Positive correlation between increased thickness in the left frontalpole cortex and PSQI scores (p = 0.038, r=0.27).
Specific sleep items correlated with increased thickness in the left entorhinal cortex and right pericalcarine cortex, with statistical significance noted.
Interpretation:
The findings suggest that sleep disturbances may influence cortical remodeling in MMT patients, potentially linked to methadone's effects, neuroinflammation, or synaptic plasticity, with implications for clinical practice.
Limitations:
Small sample size may limit generalizability.
Cross-sectional design does not establish causation.
Lack of objective sleep measures.
Absence of longitudinal data to support causal inferences.
Conclusion:
Sleep disturbances are significant modifiers of neuroanatomical changes in MMT patients, highlighting the need for sleep-targeted interventions to improve treatment outcomes.
