The invention discloses a method for rapid screening and
curative effect evaluation of
attention deficit hyperactivity disorder, and belongs to the technical field of event-related potentials,. The method comprises the following steps: 1, arranging a stimulation material for inducing cognitive
processing difference between an
attention deficit hyperactivity disorder patient and a healthy individual to form an electroencephalogram stimulation task; 2, playing the brain electrical stimulation task which is arranged before to a subject, indicating the subject to make a corresponding response according to the stimulation task, and collecting and storing
test data of the subject to obtain a brain electrical
signal of the subject; 3, performing preprocessing and
data analysis on the electroencephalogram signals of the subject, extracting waveform feature information of three components of P300, CNV (correlation
negative wave) and Pe (error positive wave), and calculating scores of all tasks; and 4, according to the basic information of the subject, performing weighted calculation on the
score of each task to obtain the total
score of the subject. The detection means for
electrophysiology assessment is provided, the detection means is simple, the detection result provides objective
pathological characteristic information, various weaknesses of current clinical assessment are effectively solved, the
pathological state can be prevented and intervened as soon as possible, the sensitivity is high, multiple measurements can be achieved, and the method is used for evaluating the
treatment effect and timely adjusting the treatment means, and is a prediction and diagnosis method for rapidly measuring obstacles.
