Early and accurate diagnosis is challenging due to the subtle and variable nature of early symptoms. This study aims to address these diagnostic challenges by proposing a novel method, Localized Region Extraction and Multi-Modal Fusion (LRE-MMF), designed to enhance diagnostic accuracy through the integration of structural MRI (sMRI) and resting-state functional MRI (rs-fMRI) data. The LRE-MMF method utilizes the complementary strengths of sMRI and rs-fMRI: sMRI provides detailed anatomical information, while rs-fMRI captures functional connectivity patterns. We applied this approach to a dataset consisting of 20 PD patients and 20 healthy controls (HC), all scanned with a 3 T MRI. The primary objective was to determine whether the integration of sMRI and rs-fMRI through the LRE-MMF method improves the classification accuracy between PD and HC subjects. LRE-MMF involves the division of imaging data into localized regions, followed by feature extraction and dimensionality reduction using Principal Component Analysis (PCA). The resulting features were fused and processed through a neural network to learn high-level representations. The model achieved an accuracy of 75 %, with a precision of 0.8125, recall of 0.65, and an AUC of 0.8875. The validation accuracy curves indicated good generalization, with significant brain regions identified, including the caudate, putamen, thalamus, supplementary motor area, and precuneus, as per the AAL atlas.

These therapies influence critical biological processes, including reducing oxidative stress, modulating chronic inflammation, enhancing immune function, and preserving telomere length-key markers of cellular aging. Additionally, these practices contribute to improved cardiovascular health, musculoskeletal strength, and mental well-being, fostering a comprehensive approach to healthy aging. Yoga, for instance, combines physical postures, breath control, and meditation to enhance physical flexibility, mental clarity, and emotional balance. Meditation practices are shown to reduce stress and improve cognitive function, further supporting healthy aging. Lifestyle modifications, such as diet and regular physical activity, complement these therapies by promoting overall vitality and reducing the risk of age-related diseases.
