A hybrid EEG MRI ResNet50 fusion network with cross modal attention for early Parkinson's disease detection using REMCAT
Parkinson's Disease (PD) is a progressive nervous system disorder marked by brain cells losing their ability to send dopamine signals, leading to tremors, stiffness, and slowness. Symptoms evolve slowly, often starting unilaterally and worsening over time, impacting sleep and mental health. This study proposes REMCAT, a novel hybrid deep learning model for early PD detection. REMCAT integrates functional EEG spectrograms and structural MRI features through a dual-branch deep learning framework, utilizing a lightweight 2D CNN for EEG and a fine-tuned ResNet50 for MRI. A cross-modal attention module fuses these features, enhancing diagnostic precision. The model achieves high accuracy and offers interpretable decision support for real-time clinical use.

Understanding Parkinson's Disease
Parkinson's Disease (PD) is a progressive neurodegenerative disorder caused by the degeneration of dopaminergic neurons, leading to motor symptoms like tremors, rigidity, and bradykinesia. Early diagnosis is challenging as symptoms often overlap with normal aging, making powerful machine learning algorithms essential. Traditional unimodal methods often fall short, highlighting the need for multimodal approaches that integrate various data sources for enhanced diagnostic accuracy and interpretability. Existing deep learning frameworks have shown promise but often lack computational efficiency and real-time applicability.
REMCAT Architecture & Data Fusion
The proposed REMCAT model employs a hybrid deep learning system integrating EEG spectrograms and MRI slices. Data is sourced from OpenNeuro (ds003490, ds005892) and PPMI for external validation. A lightweight 2D CNN processes EEG spectrograms for temporal spectral embeddings, while a fine-tuned ResNet50 extracts structural features from MRI. A critical cross-modal attention module aligns and fuses these features, with channel-wise gating refining discriminative features. Data augmentation, subject-wise splitting, and Adam optimization ensure robustness and generalization. Grad CAM visualizations provide interpretability, highlighting disease-relevant regions.
Performance & Interpretability
REMCAT achieves an accuracy of 98.3%, precision of 94.8%, recall of 98%, and specificity of 98.4%. The Cohen Kappa score is 97% and AUC ROC is 99%. Subject-wise 5-fold Group K Fold cross-validation ensures realistic generalization. External validation on the PPMI dataset yielded 93.6% accuracy and 95.2% AUC-ROC, demonstrating robust performance against domain shifts. Grad CAM images confirm the model accurately identifies disease-relevant regions in both EEG and MRI, ensuring clinical credibility and transparency.
Conclusion: An Efficient, Interpretable Solution
The REMCAT framework offers an interpretable and computationally efficient deep learning model for early Parkinson's Disease detection. By fusing EEG and MRI modalities with cross-modal attention and transfer learning, it achieves high diagnostic precision while maintaining low computational demand. This enables transparent and real-time clinical decision support, addressing key limitations of previous approaches. Future work may explore integrating additional physiological data (handwriting, vocal characteristics, locomotion patterns) and utilizing small Mobile ViT devices for enhanced real-time processing.
