Multimodal brain network topology and enhanced computer-aided diagnosis in Parkinson’s Disease: a systematic review and meta-analysis
To identify consistent multimodal global brain network alterations in Parkinson's Disease (PD) and assess the diagnostic accuracy of graph theoretical analysis (GTA) metrics, highlighting the significance of these alterations for early diagnosis.
Key Findings:
dMRI showed deficits in network segregation and integration in PD, indicating potential biomarkers.
fMRI indicated lower network segregation in PD, with no significant changes in integration, suggesting modality-specific impacts.
sMRI and EEG reported no consistent abnormalities, highlighting the need for further investigation.
Distinct patterns of network disruption were observed across modalities, underscoring the complexity of PD.
Interpretation:
The findings suggest that PD is characterized by modality-specific patterns of brain network alterations, indicating a complex dysconnectivity rather than a single underlying biological change, which may inform future research directions.
Limitations:
Inconsistencies in findings across studies, such as variations in sample sizes and methodologies.
Limited generalizability due to the variability in sample characteristics and methodologies, which may affect the applicability of results.
Conclusion:
The study highlights the potential of GTA metrics for automated early diagnosis of PD, though further validation in real-world settings is necessary.
