AI-Driven Digital Twin Framework for Targeted Sleep and Mood Treatments

Overview

This report details an innovative AI-powered digital twin ecosystem integrating gut microbiome and neuroimmune data to deliver precision interventions for sleep and mood disorders. The framework leverages multi-omics, real-time sensors, and explainable AI to optimize adaptive care pathways, including pre-/post-biotic therapies and circadian light prescriptions.

Background

The microbiota-gut-brain axis represents a complex bidirectional communication network influencing brain function and sleep regulation. Gut microbial composition and metabolites modulate neuroendocrine circuits, affecting stress response, mood, cognition, and sleep architecture. Dysbiosis is linked to neuropsychiatric and neurodevelopmental disorders, as well as sleep fragmentation and metabolic disease. Targeted microbiota-directed interventions have shown promise in restoring microbial balance and improving sleep quality.

Data Highlights

Key microbiome features associated with sleep improvements include enrichment of butyrate-producing taxa such as Faecalibacterium prausnitzii and Roseburia spp., which enhance slow-wave sleep continuity and reduce nocturnal arousals. Chronic insomnia and obstructive sleep apnea correlate with reduced microbial alpha-diversity, butyrate deficiency, and increased pro-inflammatory Proteobacteria. These microbial signatures impact metabolic, immune, and neuronal pathways that fragment sleep architecture.

Key Findings

• The G-B-S DT-N ecosystem integrates four layers: Microbiome Dynamics, Neuro-immune Interface, Sleep-Cognition-Emotion Circuits, and Person-Nurse-Environment Triad.
• Multi-omics data, EEG sleep microstructure, real-time sensors, and EMR feeds create a dynamic, patient-specific digital twin architecture.
• Uncertainty-aware explainable AI modules enable privacy, interpretability, and causal inference for precision interventions.
• Adaptive care pathways include precision pre-/post-biotic delivery and circadian light prescriptions optimized via nurse-in-the-loop reinforcement learning.
• Quantum-accelerated simulations and a proposed randomized controlled trial (D-TWIN-RCT) will evaluate efficacy versus standard care.
• Social, legal, and ethical frameworks ensure data sovereignty and patient autonomy within the ecosystem.

Clinical Implications

This AI-driven digital twin framework offers a scalable, precision medicine approach to managing complex sleep and mood disorders by targeting gut microbiome and neuroimmune pathways. Nurses play a pivotal role in delivering adaptive, personalized interventions informed by real-time data and explainable AI. The integration of microbiota-directed therapies with circadian modulation may enhance treatment efficacy and patient outcomes.

Conclusion

The G-B-S DT-N ecosystem represents a transformative advancement in microbiome-precision medicine, harnessing AI and multi-layered data integration to tailor sleep and mood disorder treatments. Its implementation could redefine nursing roles and improve management of complex comorbidities through dynamic, patient-specific care.
