Alzheimer's disease detection device and computer equipment

The invention provides an Alzheimer's disease detection device and computer equipment, and relates to the field of medical disease detection. According to the application, a brain network constructionmodule constructs a to-be-detected brain network corresponding to a to-be-detected brain; a characteristic parameter calculation module calculates a network structure characteristic parameters of target frequent sub-graphs at the to-be-detected brain network corresponding to the target characteristic parameter type, wherein the target feature parameter types corresponding to different target frequent sub-graphs comprise any one or combinations of sub-graph local clustering coefficients, sub-graph importance scores and sub-graph local importance scores; a characteristic parameter classification module inputs the calculated network structure characteristic parameters into a brain detection model to perform Alzheimer's disease characteristic classification; and therefore, under the conditionthat the human brain structure characteristics with high matching degree corresponding to the brain to be detected are obtained, a high-precision Alzheimer's disease diagnosis result is obtained, andthe artificial participation degree in the diagnosis process is reduced.
