ASSISTIVE DETERMINING DEVICE FOR ASSESSING WHETHER TRANSCRANIAL MAGNETIC STIMULATION IS EFFICACIOUS FOR PATIENT OF DEPRESSION

摘要

An assistive determining device (100 and 200) for assessing whether a transcranial magnetic stimulation is efficacious for a patient of depression. The device is provided with a feature extraction unit (104 and 224) and a machine learning unit (105 and 225) electrically connected to the feature extraction unit (104 and 224). In an interpretation mode, the feature extraction unit (104 and 224) is used for acquiring at least one eigenvalue of an electroencephalography signal of a patient, at least one classifier of the machine learning unit (105 and 225) interprets, on the basis of the at least one eigenvalue of the electroencephalography signal, whether a transcranial magnetic stimulation is efficacious for the patient, where the electroencephalography signal is an electroencephalography signal when the patient is driven by a cognitive task program or a electroencephalography signal of before and after differences, and the at least one eigenvalue is a linear or nonlinear eigenvalue. The assistive determining device (100 and 200) is capable of assessing in advance whether the transcranial magnetic stimulation is efficacious for the patient so as to avoid an ineffective treatment, which results in wastage of medical resources and money.
