The invention discloses a quantitative analysis method and device for cognitive function mapping electroencephalogram oscillation and a storage medium, and relates to the technical field of signal processing. The method comprises the steps as follows: obtaining an electroencephalogram signal of a patient in a normal state in a preset time period; acquiring an oscillation signal of the electroencephalogram signal in a preset frequency band; determining a peak frequency corresponding to the maximum power spectrum of the oscillation signal; and accurately evaluating the state of the cognitive function of the patient according to the peak frequency. According to the method, the problem of poor stability and reliability of screening means in the prior art is solved, and the effect of improvingthe accuracy of the determined cognitive competence so as to improve the stability and reliability is achieved.
Description
technical field [0001] The invention relates to a quantitative analysis method, device and storage medium for cognitive function mapping electroencephalogram oscillation, and belongs to the technical field of signal processing. Background technique [0002] There is currently no specific drug to treat senile dementia. The pre-dementia-mild cognitive impairment period is the best period for early screening and early intervention and treatment of dementia, which can effectively delay the occurrence of dementia. The current main screening method for mild cognitive impairment is the neuropsychological assessment scale for cognitive impairment, but it is greatly affected by subjective factors, and its stability and reliability are not ideal. Contents of the invention [0003] The object of the present invention is to provide a quantitative analysis method, device and storage medium for cognitive function mapping EEG oscillation, which are used to solve the problems in the prior...
