METHOD FOR ANALYZING MENTAL ILLNESS USING BIOMETRIC SIGNAL UNDER COGNITIVE STIMULI}

The present invention relates to a method for analyzing mental disorders in a mobile environment, and more particularly, to a method for measuring a mental signal using a portable sensor and a portable terminal in a state in which a cognitive stimulus is given to a user and analyzing the mental disorder using the same. will be.

In the process of rapid industrialization and westernization, mental illness of individuals due to materialisticism, moral and legal hazards, and loss of traditional culture occurs, but mental health measurement and the quantification of the degree of mental illness are difficult to manage systematically. to be. In particular, depression causes a decrease in parasympathetic nerve activity, an increase in sympathetic nerve activity, and causes abnormal blood pressure change cycles, thereby increasing the systolic blood pressure ratio between normal and sleep states. Therefore, depression can be a fatal factor in patients with heart disease, which can increase morbidity and mortality.

Depression can also lead to autonomic dysfunction, including increased heart rate, decreased HRV, abnormal heart rate changes to physical stimuli, high variation in ventricular repolarization and reduced baroflex function. Depression also increases the risk of developing coronary artery disease by up to 3.5 times. Therefore, various methods for evaluating depression have been prepared in order to put the disease caused by depression.

Depression is deeply related to many physical health, including known symptoms, access to health care, morbidity and mortality. In consideration of this, conventionally, depression was determined by conducting clinical interviews using a structural clinical interview (SCID), a Beck Depression Inventory (BDI), and the Center for Epidemiologic Studies of Depression Scale (CES-D). SCID takes a structured interview form and records the presence of each disorder in the current state (last month) and lifetime, and analyzes the recorded information to determine depression, and BDI is a mood, pessimism, mood of failure, It is a method of estimating scores based on 21 symptoms and feelings such as dissatisfaction, guilt, and self-hate, and using the calculated scores to determine depression. In addition, CES-D calculates and calculates scores using 20 items including depressed mood, loneliness and frustration, decreased appetite, and sleep disorders to measure the extent of current depression, especially depression. It is a method of determining depression using the scores.

These methods of assessing depression can be chosen differently depending on the design of the study and available resources, and self-report forms of diagnosis may indicate that some items (eg, crying) are more likely to cause behavior or mood in women. Because of the betting, the group test provides an estimate of the individual's depression, especially when women are diagnosed with more severe depression than men. SCID diagnosis can be used as an important criterion for determining depression, but it requires a lot of time and money because interviews require a lot of time and skilled clinical users.

Patients at risk for depression generally have vague symptoms such as generalized helplessness, fatigue, headache, and non-specific pain, so there are few medical tests that can be diagnosed early. Only when a doctor suspects depression is diagnosed by various psychological tests, subjective factors are likely to be involved. Therefore, efforts are needed to detect and quantify depression early in a more objective and scientific way.

Referring to FIG. 1, a mental disease management system according to an embodiment of the present invention includes a plurality of portable terminals 10 and a mental disease management server 50 connected to each other through a wired / wireless communication network.

In the present embodiment, the mental disease management system performs the function of generating reference information based on the analysis of the mental disease and the function of analyzing the level of the mental disease using the user's biosignal. Therefore, the portable terminal 10 is implemented to operate in a mode for generating and providing individual reference information necessary for generating reference information and a mode for requesting analysis of the level of mental illness of the user. In addition, the mental disease management server 50 is configured to operate in a mode of constructing a database of reference information by combining the individual reference information and a mode of analyzing the level of mental disease and providing the result.

The portable terminal 10 provides an interface that allows the user to select one of the two modes (the mode for generating and providing individual reference information and the mode for requesting analysis of the level of mental illness of the user). For example, the portable terminal 10 displays an icon or a character representing two modes on the initial screen of the display, and selects one of the two modes by moving an arrow or the like or inputting a number key. I can receive it.

When the portable terminal 10 is set to a mode in which individual reference information is generated and provided by a user's selection, the portable terminal 10 displays questions that can grasp the level of mental illness of the user through a display, Receive a reply. Then, the level of mental illness is measured according to the response result. In addition, the portable terminal 10 receives the user's biosignal after measuring the level of mental illness using a question. In this case, the portable terminal 10 provides a means for giving a cognitive stimulus through a display, thereby exposing the user to an environment that can receive the cognitive stimulus. For example, the means for giving a cognitive stimulus may be a program that can perform a Stroop color word conflict test using a portable terminal. In addition, the portable terminal 10 generates the individual reference information by combining the response to the questions and the bio-signals input in the environment in which the user receives the cognitive stimulus, and the individual reference information to the mental disease management server 50 To send.

Preferably, the portable terminal 10 may receive the biosignal of the same user as the user who answered the question at predetermined intervals and generate biosignal pattern information by analyzing the pattern of the input biosignals. Further, the individual reference information may include the bio signal pattern information.

On the other hand, when the portable terminal 10 is set to a mode for requesting analysis of the mental disease level by the user's selection, the portable terminal 10 exposes the user to an environment that can give a cognitive stimulus through the display, and the user Receives a bio signal of. The biosignal is transmitted to the mental disease management server 50 to request an analysis of the mental disease level. Furthermore, the portable terminal 10 receives the user's biosignal at predetermined intervals and generates biosignal pattern information analyzing the pattern of the received biosignals. The biosignal and the biosignal pattern information may be transmitted to the mental disorder management server 50 to request an analysis of the mental disorder level.

The mental disease management server 50 is set according to the information transmitted by the portable terminal 10. That is, the mental disease management server 50 stores the individual reference information received in consideration of a predetermined rule in accordance with a predetermined rule as receiving an identifier for requesting the generation of the reference information together with the individual reference information from the portable terminal 10. .

That is, the controller 21 performs a process according to the number and menu selection signal input through the key input unit 24, performs a process of the signal received through the biosignal measurement module 11, and measures the biometric The information on the signal and the mental disease level is stored in the memory unit 22, and the pattern information generation unit 15 and the individual reference information generation unit 17 generate the pattern information and the individual reference information by using the stored information. To control. In addition, the controller 21 outputs a plurality of questions for obtaining information on the mental disease level, the generated pattern information, individual reference information, and the like through the display unit 23. At this time, if necessary, the contents to be output stored in the memory 22 are brought, or the contents are stored in the memory 22. The memory unit 22 also stores a number of programs and data related to the operation of the control unit 21.

In addition, when the controller 21 receives a 'check for mental illness level' menu from among menu items provided in the mobile communication terminal, the controller 21 may be stored in the biosignal (or cognitive jog) previously stored in the memory unit 22. The bio-signal measured in real time) is transmitted to the user terminal 30, the request for analysis of mental diseases, the result is received and stored in the memory unit 22, the user can confirm through the display unit 24 To be displayed.

The display unit 23 may be formed of a display device such as a liquid crystal display (LCD). The display unit 23 displays digital image data captured by the controller 21 and a message regarding various operating states of the terminal. do. The key input unit 24 is a device for receiving a telephone number or a character from a user, and includes keys for inputting numeric and character information and function keys for setting various functions, and inputs the input signal to the controller 21. Output

The radio unit 25 modulates a user's voice, text, and control data into a radio signal and transmits the signal to a base station (not shown) of a mobile communication network, receives a radio signal from the base station, and demodulates it into voice, text, control data, and the like. do. The wireless data processing unit 26 decodes the voice data received by the wireless unit 25 under the control of the control unit 21 and outputs the audible sound through a speaker, and the user's voice is input from a microphone. The signal is converted into data and output to the wireless unit 25, and the character and control data input through the wireless unit 25 are provided to the control unit 21.

A portable terminal having such a configuration performs a typical mobile communication service related operation, wherein the control unit 21 uses a function of generating individual reference information according to the features of the present invention and a user's biosignal in addition to the above functions. Function to identify the level of mental illness.

On the other hand, the biosignal (eg, heart rate microvariation) changes from time to time according to the state of the autonomic nervous system and the cardiovascular system, and the normal range may be different for each individual. Therefore, by measuring the biosignal in consideration of the circadian rhythm of the biosignal, it is possible to more accurately measure mental diseases. To this end, it is preferable that the mental disease management system according to an embodiment of the present invention further includes a biosignal pattern information generation unit 15.

The biosignal pattern information generation unit 15 generates biosignal pattern information by combining the biosignals output from the biosignal measurement module 11. The biosignal pattern information is information generated by using a biosignal input at predetermined intervals. For example, the biosignal pattern information includes five predetermined intervals of a heartbeat signal (9 to 12, 12 to 15, and 15). The heart rate signal is measured at least once every hour (hours-18:00, 18:00-21:00, 21:00-24), and the result can be CV information and Hfn.u. information indicating a change pattern.

Furthermore, the biosignal pattern information generation unit 15 preferably includes an alarm for informing the user to recognize that the user inputs the biosignal at predetermined intervals. The alarm includes five predetermined intervals, for example, a first section of 9:00 to 12 o'clock, a second section of 12 to 15:00, a third section of 15:00 to 18:00, a fourth section of 18:00 to 21:00, Set a fifth section of 21:00 to 24 hours, and each time one of the sections is reached, repeatedly warns until a bio signal measured at a predetermined time interval (for example, 10 minutes) is input. It can be set to.

Although the predetermined section is illustrated as five sections as described above in the embodiment of the present invention, the present invention is not limited thereto. The predetermined section may be freely set by the user. To this end, the mobile communication terminal may be implemented to set a predetermined section from the user by executing at the time of selection of the 'biological signal pattern information setting' menu among the menu items for setting various functions. In addition, the predetermined section may be fixedly provided to a value appropriately set by the developer.

3 is a block diagram of the mental disease management server 50 provided in the mental disease management system according to an embodiment of the present invention. Referring to FIG. 3, the mental disease management server 50 according to the embodiment of the present invention may include a communication interface 51, a controller 52, a reference information manager 53, a mental disease analyzer 54, and reference information. Database 61 is included.

The communication interface 51 is an interface for transmitting data between the portable terminal 10 and the server 50, and any type of interface capable of transmitting data through a wired / wireless communication network may be used.

The control unit 52 controls the overall operations of the server by controlling the operations of the respective functional units as a whole. That is, the controller 52 confirms the data received through the communication interface 51 and instructs operations of the reference information manager 53 and the mental disorder analyzer 54 based on the commands included in the data. do.

The reference information management unit 53 stores and manages individual reference information received from the user terminal 10 in the reference information database 61 in consideration of the mental disease level and the result. Then, the reference information management unit 53 classifies the group having the mental disease using the questionnaire result, and forms the standard of the mental disease level based on the biosignal input from the experimental group belonging to each group.

As the mental disease analysis unit 54 receives a mental disease analysis request from the portable terminal 10, the mental disease analysis unit 54 analyzes the mental disease using the biosignal.

Since various mental actions are shown as dynamic changes in the heartbeat interval through the regulation of the autonomic nervous system, it is possible to analyze the level of mental diseases by analyzing heart rate variability (HRV). In particular, in patients with depression, when cognitive stimulation is caused by an external factor, the heart rate of SDNN, CV, etc., which is significantly lower than a normal person, is measured. Therefore, it is possible to analyze the degree of depression by confirming how low the heart rate measured in the cognitive stimulus environment is measured based on a normal person, and statistically analyzing by age and gender. As a result, in the exemplary embodiment of the present invention, the biosignal may be a signal measuring heart rate, and the mental disease is preferably depression.

On the other hand, the reference information DB (61) is classified in the mental disease questionnaire results, the mental disease level corresponding to the response results, information such as the age and gender of the user participating in the response, and the individual reference information including the bio-signal of the user is classified And the information is managed in association with each other. Therefore, the mental disease analysis unit 54 may check the mental disease level corresponding to the biological signal with reference to the reference information DB 61. That is, when receiving the bio-signal from the portable terminal 10 and receiving a mental disease analysis request, the reference information DB 61 is checked to extract individual reference information corresponding to the bio-signal in the DB. In addition, the mental disease level included in the extracted individual standard information is checked.

In addition, the mental illness management server 50 may provide information related to mental illness through a website. To this end, the mental disease management server 20 is a site operation unit 55 for operating the site according to the algorithm for driving the website and various information necessary for the operation of the site, for example, operation information such as web pages, images, hyperlinks DB information for storing the operation information DB 65, a member information DB 66 for storing the member ID, password, the user terminal identification code of the members, etc., and the living body received from the user terminal 10 of each member It may further include a bio-signal DB (67) for storing the signal. The mental disease management server 50 may not only provide the level of the mental disease corresponding to the measured biosignal, but may also provide various ways to solve the mental disease in response to the level of the mental disease. For example, a treatment method corresponding to the level of mental illness may be input and provided from a user having expertise in mental illness, or may be provided by receiving a solution of a user who has experienced mental illness.

4 is a block diagram of a mental disease management system according to another embodiment of the present invention. Referring to FIG. 4, the mental disease management system according to another embodiment of the present invention uses a user terminal 30 as a medium for mediating an embodiment of the present invention and the portable terminal 10 and the mental disease management server 50. It may further include.

The user terminal 30 may be a general personal computer (PC) equipped with a mental disease management program. The user terminal 30 may be implemented to perform the function of the mental disease analysis unit 54 of the mental disease management server 50 provided in an embodiment of the present invention, from the mental disease management server 50 Information contained in the reference information DB 61 may be frequently received and stored and managed in the memory. As the user terminal 30 is configured as described above, since the user terminal 30 performs a function of analyzing a mental disease, the mental disease management server 50 does not have to have a mental disease analysis unit 54.

Hereinafter, the operation of the mental disease analysis method according to the present invention will be described in detail with reference to the accompanying drawings.

5 is a flowchart illustrating a method for analyzing mental disorders according to an embodiment of the present invention, and FIG. 6 is a flowchart illustrating the process of step 100 of FIG. 5 in detail. 5 and 6, the mental disease analysis method according to an embodiment of the present invention generates reference information that is a reference for discrimination between the normal group and the mental disease group when the mental disease analysis before the mental disease analysis proceeds; (Step 100).

Preferably, step 100 is performed through learning of mental disease questionnaire results and bio-signals input from an unspecified number, and may include steps 110 to 200 (see FIG. 8). First, step 110 is performed by the user selecting a menu provided for generating reference information among menus provided in the mobile phone. For example, if the menu provided to generate the reference information in the mobile phone is the 'individual reference information generation' menu, step 110 is performed as the user selects the 'individual reference information generation' menu. When the 'Generate Individual Criteria Information' menu is selected, the portable terminal preferentially receives a user's age and gender, and selects a plurality of SRI questionnaires corresponding to the mental illness questionnaires stored in the memory. The selected mental illness questionnaire is displayed on the portable terminal (step 120), a response thereto is received (step 130), and the result is stored (step 140). Steps 120, 130, and 140 are repeatedly performed until the selected plurality of mental diseases questionnaires are completed. When the questions and answers of the selected mental illness questionnaires are completed (145-Yes), the user who responds to the mental illness questionnaire is exposed to a cognitive stimulus environment (step 150). For example, step 150 may be implemented by displaying a Stroop color word conflict test that may give a cognitive stimulus to the portable terminal. That is, a letter made of a specific color and an option for selecting the color of the letter are displayed on the portable terminal, and one of the options is received from the user.

Although, in the embodiment of the present invention, the environment for providing the cognitive stimulus illustrates that the implementation of the Stroop color word conflict test in the portable terminal, the present invention is not limited to this, for example, it can give a cognitive stimulation It is sufficient if the portable terminal can run a test method, a game that can give a cognitive stimulus, and the like.

Next, in operation 160, the bio signal of the user is input from a sensor connected to the body of the user exposed to the cognitive stimulus. The sensor may be a sensor attached to a part of a user's body to detect a heartbeat and to be portable.

In operation 160, it is preferable to measure the biosignal in consideration of the change in the one-cycle pattern of the biosignal. For example, the work cycle is the first section between 9:00 and 12:00, the second section between 12 and 15:00, the third section between 15:00 and 18:00, the fourth section between 18:00 and 21:00, and between 21:00 and 24:00. In order to measure the bio-signal of the user responding to the mental disease questionnaire, at least one bio-signal is measured at each section. That is, the bio-signals are measured at least once in each section until the five sections of the cycle pass at least once from the section where the mental disease questionnaire is completed. The number of times the bio signal is measured in each section (e.g., the bio signal is measured three times in each section for 24 hours after the response of the questionnaire is completed) or the number of times the bio signal is measured by repeating one cycle (e.g., each The biosignal is measured once during the interval, but the biosignal is measured for three days). Furthermore, the present invention does not limit the number of times of measuring the bio-signals, and the number of times may be determined according to an algorithm for generating reference information which is a reference for mental disease analysis. Further, when measuring the biosignal in consideration of the change in the one cycle pattern in step 160, the biosignal pattern information including the pattern of the biosignal measured during the one cycle is generated. For example, the biosignal pattern information includes curve fitting of a biosignal measured during one period in a quadratic equation, determining an effective point among the curve-fitted points, and forming a pattern formed by the determined points. Generate with information

Next, when the measurement of the bio signal is completed for one cycle, step 170 is performed. In step 170, individual reference information associated with the biological signal and the mental disease response result is generated. The generated individual standard information may be provided to the mental disease management server, and the plurality of individual standard information thus provided are stored in the user terminal or the mental disease management server. As a result, the mental disease management server combines individual standard information provided from a plurality of users to generate standard information classified according to predetermined criteria (eg, mental disease level according to gender and / or age) (step 180). ).

In the above, the above-described step 100 may be continuously repeated at the request of the portable terminal user, and the reference information may be continuously updated through learning. Furthermore, by continuously updating individual reference information from an unspecified number of users, biosignal pattern information of various groups of users can be secured, and various and many samples can be obtained to perform mental disease analysis more accurately.

On the other hand, step 200 is performed by the user selecting a menu (eg, 'mental disease analysis' menu) prepared for requesting the mental disease analysis from the menu provided in the portable terminal. Specifically, the portable terminal receives a menu prepared for mental illness analysis from the user, and the portable terminal measures the user's biosignal. The measurement of the biosignal is performed through the same process as that of the aforementioned steps 150 and 160.

As such, when the biosignal is measured in the cognitive stimulus environment, the biosignal is transmitted to a medium (for example, the mental disease management server, etc.) analyzing the mental disease level using the biosignal and requesting the mental disease analysis (step 300). ).

Although the embodiment of the present invention illustrates that the portable terminal selects a menu prepared for mental illness analysis from a user and generates a bio signal in real time, the present invention is not limited thereto. For example, after the user measures the bio-signal in advance and stores it in the portable terminal, it is also possible to request a mental disease analysis by selecting the stored bio-signal as needed.

Next, the medium (eg, mental illness management server, user terminal, etc.) analyzing the mental disease level receives a biosignal such as CV or SI, and confirms the mental disease level corresponding to the biosignal (step 500). . Specifically, the individual reference information having the biosignals similar to the biosignals of the group corresponding to the gender or age of the user who measured the biosignals in the reference information is extracted. In addition, the response result of the mental disease questionnaire included in the individual standard information is checked, and the level of the mental disease based on this is determined, and it is determined as the level of the mental disease of the user.

7 illustrates reference information stored in a database to which the mental disease analysis method according to an embodiment of the present invention is applied. Referring to Table 7, for example, it is assumed that the mental disorder is depression, the gender input from the user requesting the mental disorder measurement is male, the age is 31 years old, and the CV of the measured biosignal is 5.011 and the SI is 75.12. . Since the CV and SI of the measured biosignal pattern information are similar to the quadratic equation of the biosignal pattern information of identification number 130002 of the reference information, the identification number 130002 is extracted as individual reference information. Then, the depression level of the extracted individual reference information is checked.

Finally, the mental disease level identified in step 600 is returned to the portable terminal, the portable terminal displays the returned result through the liquid crystal (step 700).

Although, in the mental disease analysis method of the present invention, the mental disease management server receives individual reference information from a plurality of portable terminals, generates and updates the reference information using the individual reference information, and uses the updated reference information. To analyze mental illness and provide results. However, the present invention is not limited thereto, and various methods of analyzing mental diseases may be used, including a portable terminal and a mental disease management server. For example, the mental disease management server receives individual reference information from a plurality of portable terminals, generates reference information, and performs only a function of providing reference information to a user terminal (eg, a general personal computer), and the user terminal has a mental disease. It is also possible to store the reference information stored in the management server in a separate memory, to continuously update the basic information, and to analyze the mental disease using the reference information and mental disease analysis tool stored in the user terminal.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto, and various modifications and changes may be made by those skilled in the art to which the present invention pertains.
