The invention discloses a rapid
eye movement period
sleep behavior disorder classification method based on sleep electroencephalogram. The method comprises the following steps: preprocessing an acquired sleep electroencephalogram
signal of a patient, acquiring an electroencephalogram
signal of an electroencephalogram interval in a sleep R period,
cutting according to a preset
signal length to acquire a plurality of sub-signal segments, layering an original electroencephalogram signal of each sub-signal segment, and enabling a
frequency domain component after
wavelet transform to approximatelycorrespond to different wave bands of original electroencephalogram according to the frequency of the electroencephalogram; carrying out empirical mode
decomposition (EMD) to obtain a multilayer intrinsic mode function (IMF); performing
feature extraction on the electroencephalogram signals of different wave bands and the multilayer intrinsic mode function, and performing dimensionality reductionon the
feature set PCA to obtain a low-dimensional
feature set; and carrying out classification and identification by using the
feature set after dimension reduction, and classifying patients suffering from Parkinson's
disease accompanied by rapid
eye movement sleep disorder, Parkinson's
disease not accompanied by rapid
eye movement sleep disorder and idiopathic rapid eye movement period
sleep behavior disorder. Complex PSG detection is simplified into electroencephalogram detection, a whole night does not need to be consumed, the number of times of measurement is reduced, an accurate recognition result is obtained, and then a very good auxiliary effect can be achieved on treatment of the illness state of a patient.
