Embodiment Construction

[0040] The present invention is described further below by embodiment.

[0041] see Figure 1 to Figure 4 .

[0042] This example is carried out on the premise of the technical solution of the present invention, and detailed implementation and content are given, but the scope of the present invention is not limited to the following examples.

[0043] The implementation process mainly includes six stages (such as figure 1 shown). The first step is to screen the subjects with the main complaint of memory decline; the second step is to conduct the necessary psychological tests; the third step is to carry out the learning and memory of emotional faces; the fourth step is to carry out the face recognition test after 1 hour of learning, and Record the EEG; fifth, conduct the emotional face recognition test again at the same time the next day, and record the EEG; sixth, perform data analysis and processing.

[0044] 1. Screening subjects

Abstract

The invention relates to a method utilizing event-related potentials equipment to assist in screening mild cognitive impairment. The method adopts the event-related potentials technology to assist in screening mild cognitive impairment (MCI) and judging clinical intervention effect, adopts the learning-recognizing experimental mode to allow a testee to learn and recognize three emotional faces (positive, neutral and negative) during operation, and also utilizes event-related electrocortical potentials equipment to record the electroencephalogram of the testee. Collected data are calculated according to the unique algorithm, so that four indexes, such as the response accuracy, the N170 ingredient, the early-stage old / new effect and the late-stage old / new effect of the testee, become effective indexes for recognizing MCI, and the method is used for early-stage diagnosis and curative effect determination of MCI, is noninvasive, can be easily accepted by patients and is suitable for clinical popularization.

Description

technical field [0001] The invention relates to a method for assisting screening of mild cognitive impairment by using an event-related potential (ERPs) instrument. Background technique [0002] Senile dementia (Alzheimer's disease, AD) is a continuous and progressive mental decline, and there is no effective treatment, the etiology is complex, and early identification is difficult. Mild cognitive impairment (mild cognitive impairment, MCI) is considered to be the early stage of AD, which is a state of cognitive impairment between AD and normal aging. During the evolution from normal people to dementia, the subjects will obviously show a decline in intelligence, the most prominent performance is memory decline. During the period of mild cognitive impairment, the subjects will show a decline in the ability to remember new events. Patients often worry about missing important events and occasions, and housewives also show changes in cooking tastes because they forget how much...
