A multi-modal coordinated cognitive improvement oscillation induced neuromodulation method and device

Abstract

This invention belongs to the field of medical device technology, and particularly relates to a multimodal synergistic cognitive improvement oscillation-induced neuromodulation method and device. The method includes: acquiring the patient's electroencephalogram (EEG) signals; obtaining clean signals through signal processing and extracting EEG characteristic parameters; initializing corresponding weights by combining the inherent modulation and safety coefficients of each modality's stimulation; dynamically adjusting the weights; obtaining the final synergistic weights through cross-modal complementary correction; constructing a multimodal parameter coupling optimization model, incorporating safety and coupling constraints, and using an optimization algorithm to solve for the optimal combination of each modality's modulation parameters; synchronously scheduling the frequency and phase of multimodal stimulation, adjusting parameters through real-time feedback, and constructing a cross-modal conflict avoidance mechanism; calculating the synergistic gain state correction coupling and complementarity coefficients, and thereby enhancing the multimodal stimulation effect. This invention effectively improves the effectiveness of treatment methods for cognitive impairment, and reduces treatment difficulty and cost.
