Abstract

The invention is applicable to the technical field of computers, and provides a method, a device and terminal equipment for detecting risk of Alzheimer's disease (AD). The method includes: acquiring electroencephalogram data corresponding to N channels of a subject; calculating a global energy spectrum according to the electroencephalogram data corresponding to each channel, and determining microstate characteristics of a preset category according to the global energy spectrum and the electroencephalogram data of each channel; marking the micro-state feature corresponding to each time point according to global field power corresponding to each time point in the global energy spectrum to obtain a global feature; and inputting the global characteristics and the electroencephalogram data intoa deep convolution neural network model to obtain an Alzheimer's disease risk evaluation result of the subject. The method, device and terminal equipment comprehensively consider the voltage amplitude change information of the electroencephalogram data and the spatial topology information of the global feature, can make the output result of the deep convolutional neural network model more accurate, can not only improve efficiency of Alzheimer's disease risk assessment, but also improve accuracy of the Alzheimer's disease risk assessment result.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method, device and terminal equipment for detecting the risk of Alzheimer's disease. Background technique [0002] Alzheimer's disease (AD) is a common degenerative disease of the central nervous system. Its clinical manifestations are cognitive decline, memory loss, and difficulty in concentrating, which seriously affects its daily life, and is accompanied by brain atrophy. [0003] At present, EEG is usually used as the basis for the diagnosis of Alzheimer's disease in medicine. EEG has high temporal resolution and is relatively cheap. Doctors usually give risk assessment results based on experience for the obtained EEG. This method It requires a lot of clinical accumulation by doctors, and the processing efficiency is slow and the accuracy is low. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a method, ...
