Embodiment Construction

[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0064] In view of the problems existing in the existing manual assessment methods, the inventor of this case conducted research and found that the cognitive ability of the subject to be assessed can be assessed by using the brain image of the subject to be assessed, and the cerebrospinal fluid of the subject to be assessed can also be extracted. Analysis of specific components in cerebrospinal fluid assesses the cognitive abilities of the subject being evaluate...

Abstract

The invention provides an object cognitive evaluation method, a device, equipment and a readable storage medium. The method comprises the following steps: firstly, acquiring a target electroencephalogram signal of a target object; secondly, segmenting the target electroencephalogram signal according to specified lengths to obtain a target signal segment set consisting of target signal segments with the specified lengths; thirdly, determining frequency domain characteristics corresponding to the target signal segments in the target signal segment set; and finally, evaluating a cognitive condition of the target object according to the frequency domain characteristics corresponding to the target signal segments in the target signal segment set. According to the cognitive evaluation method ofthe object, a cognitive condition of the target object can be automatically evaluated by using the electroencephalogram signal; an evaluation basis is the electroencephalogram signal which can reflectan activity state of a human brain, so that an evaluation result is not influenced by an education degree of the target object; and in addition, the evaluation method provided by the invention is high in efficiency and low in cost, is convenient and fast, and has strong universality.

Description

technical field [0001] The present application relates to the field of smart medical technology, and in particular to a cognitive evaluation method, device, equipment and readable storage medium of an object. Background technique [0002] In some cases, it is necessary to assess the cognitive ability of the target audience, for example, as the population ages, the number of patients with Alzheimer's disease continues to increase, Alzheimer's disease is accompanied by cognitive decline, life disability Self-care, which greatly affects the life of the elderly. Mild cognitive impairment is a state between normal aging and Alzheimer's disease. Among the elderly with mild cognitive impairment, 10% to 30 % will be converted into Alzheimer's disease, but Alzheimer's disease is irreversible, therefore, it is necessary to evaluate the cognitive ability of the elderly in time to determine the degree of the patient's disease, so that the patient can receive intervention treatment, so a...
