Method for screening of schizophrenia

 

(57) Abstract:

The invention relates to medicine, namely to psychiatry. The patient is shown the information load and the background register CARDIORHYTHM, galvanic skin reflex and myogram. Information for presentation taken from the scripts of the videos, where traced the action scenes, which are strong irritants and cause violent emotional reaction in a healthy person. Record the time for action moments of the film in terms of heart rate with galvanic skin reflex, strength, and nature of irritation diagramme in the dynamics of a video. At the end of the test in subjects estimate the boundary of the deterioration mechanisms of homeostasis, and changes in the internal emotional state, not the external reactions of the body, as well as the mismatch emotional reaction force and the nature of the stimuli, low mobility and delay senses assess the condition characteristic of schizophrenia. The method allows to automate a preliminary diagnosis of schizophrenia.

The invention relates to the diagnosis of schizophrenia and can be used for preity person depends on the physical organization with legacy Fund individual characteristics, the conditions in which people live [1] . There are methods that define intellectual human characteristics that are different games, picture, and other tests; the lack of them is a hand-held information processing, which requires a lot of time and relevant experts [2] . There is a way to determine levels of emotional stress [3] in which to improve the accuracy determine the electrical resistance of the skin by direct current with the establishment of the electrodes on the forearm, the data are compared with several surveys; however, this method does not assess the intellectual abilities of a person. There is a way to assess the functional state of the Central nervous system [4], which consists in the fact that the individual submit a test job-as an image of a number of 12 digits, Cuba Linge, 10 words by ear and 80 cards to sort into groups and register the correct perception of numbers or words, and the test time folding cube Linke - the degree of deviation from the factor outside the specified limits judged about the change in the functional state of the Central nervous system [4] , the disadvantage of this method is that by the invention is a method for determining the purpose [5] , in which the subject produces a task on a continuous approximation of the object of continuous exposure to the governing body registration electrocardiogram and galvanic skin reflex, then measure the total solution time and the desired time and to determine their relationships reveal the degree of commitment were examined. Positive in this method is the use of temporary regulations on execution, and the disadvantage that it is quite difficult to record the electrocardiogram in performing the work of the child, in this way it is impossible to assess the intellectual abilities of the child of preschool age.

The objective of the present invention to automate the method of screening of schizophrenia.

This object is achieved in that the use of information load with the myogram, heart rate and galvanic skin reflex, and the information for the subject is taken from the scripts of movies where traced dramatic plots, which are strong irritants and cause violent emotional reaction in a healthy person, when this occurs, the response time on the stellar moments of the film in terms of film, at the end of the test to evaluate the boundary of the deterioration mechanisms of homeostasis and changes in the internal emotional state, not the external reactions of the body, as well as the mismatch emotional reactions, strength and nature of irritation, low mobility and delay senses assess the condition characteristic of schizophrenia.

The proposed method is as follows. The subject wear sensors to register the myogram, heart rate and galvanic skin reflex. Surface myogram can register with the skin on the projection of the masticatory muscles or other body parts. The information for the subject is taken from the scripts of the videos, where traced the action scenes, which are strong irritants and cause violent emotional reaction in a healthy person. When this occurs, the response time on the stellar moments of the film in terms of heart rate with galvanic skin reflex, strength and character to implement in the dynamics of a video. For example, bloody scenes, moments of disaster or murder capture reaction muscular strength and nature of irritation. Emotional response is assessed deterioration mechanisms of homeostasis, the changes in the internal emotional state, not the external reactions of the body; secrete overly pronounced reaction or no reaction. The mismatch emotional reactions, strength and nature of irritation, low mobility and delay senses assess the condition characteristic of schizophrenia.

Examples of specific performance:

1. male, 23 years: to view the action of the film registered a pulse rate of 65 beats per minute, skin resistance 108 macroom, single contraction of the muscles of 0.11 with; in the dynamics of a video on the action scenes, the heart rate was 140 beats per minute, skin resistance 45 macroom, single contraction of the muscles of 0.7 C. Conclusion: the physiological response in the dynamics of psycho-physiological load does not correspond to emotional reactions, strength and nature of the stimuli, which is characteristic of schizophrenia, you should consult a psychiatrist.

2. Male, 21 years: to view the action of the film registered a pulse rate of 70 beats per minute, skin resistance 106 macroom, single contraction of the muscles 0.15; in the dynamics of a video on the action scenes, the heart rate increased to 83 beats per minute, the skin is in the dynamics of physiological work within normal limits, consultation with a psychiatrist is not required.

3. Male, 22 years: to view the action of the film registered a pulse rate of 68 beats per minute, skin resistance 103 macroom, single contraction of the muscles of 0.13 s; in the dynamics of a video on the action scenes, the pulse rate was 72 beats per minute, skin resistance 101 macroom, single contraction of the muscles 0,11 C. Conclusion: the physiological response in the dynamics of psycho-physiological load does not correspond to emotional reactions, strength and nature of the stimuli, which is characteristic of schizophrenia, you should consult a psychiatrist.

Method for screening of schizophrenia, including information load with registration of heart rate and galvanic skin reflex, characterized in that additionally registers myogram, lausiaca strong irritants and cause violent emotional reaction in a healthy person, when this occurs, the response time on the stellar moments of the film in terms of heart rate with galvanic skin reflex, strength and nature of irritation diagramme in the dynamics of a video, at the end of the test in subjects estimate the boundary of the deterioration mechanisms of homeostasis, and changes in the internal emotional state, not the external reactions of the body, as well as the mismatch emotional reaction force and the nature of the stimuli, low mobility and delay senses assess the condition characteristic of schizophrenia.
