SYSTEMS AND METHODS FOR PROVIDING NEUROSTIMULATION THERAPY USING MULTI-DIMENSIONAL PATIENT FEATURES
The present disclosure provides systems and methods for providing neurostimulation therapy using multi-dimensional patient features. The multi-dimensional patient features may include features in respective frequency bands for selected cortical sites from EEG localization data. Additionally or alternatively, the multi-dimensional patient features may include features from patient physiological data or other patient activity data. The multi-dimensional feature data may be compared against AI/ML models of patient and/or healthy population members. Closed-loop therapy adjustments may be applied to a respective patient's neurostimulation therapy using the multi-dimensional patient feature analysis.
