The invention belongs to the technical field of monitoring and intervention of the emotional state of a mental disorder patient, and particularly relates to a wearable portable mental disorder closed-loop self-adaptive diagnosis and
treatment system based on an acoustic-optical-electric technology, which comprises an electroencephalogram and near-
infrared acquisition and analysis module, a self-
adaptive control module and an intervention module, wherein the electroencephalogram and near-
infrared acquisition and analysis module comprises a physiological
signal sensor and is used for acquiring electroencephalogram and near-
infrared data of a patient in real time, preprocessing the electroencephalogram and near-infrared data, extracting key
diagnosis evaluation indexes, quantifying the depressive state of the patient and outputting electroencephalogram and near-infrared feature vectors representing the current depressive state of the patient; the
adaptive control module is used for calculating an optimal intervention scheme and parameters according to the electroencephalogram and near-infrared feature vectors, and forwarding the optimal intervention scheme and parameters to the intervention module; the intervention module integrates various non-
drug treatment modules and executes corresponding intervention actions according to the intervention scheme and the parameters.
