Embodiment Construction
[0054] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0055] Such as figure 1 As shown, this embodiment discloses a method for evaluating post-injury cognitive function of brain-injured patients, comprising the following steps:
[0056] S1) if figure 2 As shown, a visual stimulus flow is presented to the tester, and the visual stimulus flow includes the executive stimulus flow and the inhibitory stimulus flow; the tester includes a normal person and a brain-damaged patient, and the normal person is a healthy person who has not experienced brain damage or other neurological disorders with normal cognitive function;
[0057] S2) Make the tester observe the visual stimulus flow, perform execution response when observing the execution...

The invention discloses a method and system for evaluating the post-injury cognitive function of a brain injury patient. The method comprises the steps of firstly presenting a visual stimulation flow to a testee, wherein the visual stimulation flow comprises an execution stimulation flow and an inhibition stimulation flow; collecting an electroencephalogram signal generated in the process of observing the visual stimulation flow by the testee; processing the electroencephalogram signal to obtain electroencephalogram information graphs, wherein the electroencephalogram information graphs include an electroencephalogram waveform graph, an electroencephalogram time-frequency graph and an electroencephalogram function connection graph; and taking electroencephalogram information graphs obtained by testing a normal person as a normal control group, comparing the electroencephalogram information graphs obtained by testing the brain injury patient with the normal control group, judging whether a first condition, a second condition and a third condition are simultaneously met or not, and if so, finally evaluating that the recovery of the post-injury cognitive function of the brain injury patient is good, otherwise, evaluating that the recovery of the post-injury cognitive function of the brain injury patient is poor. The invention further discloses the system based on the method. According to the invention, the recovery condition of the post-injury cognitive function of the brain injury patient can be effectively evaluated.
Description
technical field [0001] The invention relates to the technical field of cognitive evaluation, in particular to an evaluation method and system for post-injury cognitive function of brain-injured patients. Background technique [0002] At present, imaging technology is mainly used to diagnose and detect the acute phase of brain injury patients such as traumatic brain injury and TBI in clinical practice. The technologies used mainly include computerized tomography (CT) and structural magnetic resonance (structural imaging). magnetic resonance image, SMRI), but compared with the acute stage, morphological abnormalities are significantly reduced in the functional recovery period after brain injury, thus weakening the diagnostic value of CT, MRI and other techniques in the recovery stage of traumatic brain injury. [0003] Compared with imaging techniques, electroencephalography (EEG) has the advantages of good millisecond-level temporal resolution, good portability, and low cost....
