Description

The invention belongs to the field of medical technology, neuropsychiatric devices and is intended for early diagnosis of human depression.

Depressive disorder (hereinafter referred to as DS) is a progressive mental illness that has a negative impact on a person's work, social and household functioning, shortening the life expectancy of a healthy and quality life. Although DS usually develops gradually, a significant proportion of individuals do not recognize the primary symptoms of the disorder and seek help only when the disorder becomes severe. DS should be recognized, diagnosed, and treated as early as possible, and the use of devices for early diagnosis of human depression is critical as it facilitates the identification of the first symptoms of DS and the identification of subjects (TAs) in need of DS treatment.

Currently, psychiatrists rate the severity of DS symptoms using neuropsychiatric questionnaires and typically use a structured “Montgomery and Asberg Depression Assessment Questionnaire,” which consists of 10 questions about TA DS over the past week. Responses are rated on a 7-point scale (0 for no symptom, 6 for very severe symptom). The sum of the scores indicates the clinical manifestation of DS symptoms from asymptomatic to severe.

Currently, diagnosing early DS is hampered by the following:

TA or the patient avoids checking or consulting a psychiatrist for stigma;

clinical-diagnostic questionnaires are extensive, psychiatrists evaluate TA emotions subjectively, without applying modern computerized research of facial emotions.

Leppanen J. et al. (2017) PLoS ONE 12 (6): e0178972, a computerized analysis of facial emotions in eating disorders in individuals with eating disorders, is known. facial emotions. The aim of this study was to test computerized facial emotion expression analysis software to determine the regularities of facial emotion changes in different groups of participants with eating disorders. The study included 297 subjects who were divided into 4 groups: patients with anorexia nervosa (NA), patients with bulimia nervosa (NB), recovered from anorexia nervosa (PNA), and control group (K), who had neither bulimia nervosa nor anorexia. Participants watched short films evoking happy or sad emotions, and their facial expressions were analyzed using FaceReader software. Less pronounced positive facial emotions were found in the NA group than in the K group. Fewer positive facial emotions occurred in the NB and PNA groups. In the K and PNA groups, compared to the NA group, significantly more positive emotions were scanned in facial expressions. The conclusion of the research positively evaluated the computerized research equipment and methods of facial emotions (expressions). The disadvantage of this study is that FaceReadar’s equipment, method, and program did not show a relationship between subjects ’mental state, DS, emotional expressions, and eating habits.

The known invention "Method and Questionnaire for Assessing the Emotions of Product Consumers" (US20100185564A1 G06Q90 / 00) is intended for the development of a system of emotional response of individuals to different foods. It includes a research block on different facial emotions caused to consumers by different foods, and questionnaires (lists of terms describing emotions) to describe the emotions caused to the consumer by the product. The description of the method draws attention to a person’s mood and mental state as factors that determine product choice. This method is only sufficient to assess consumer emotions related to product-induced emotions and mood, but is not sufficient for early diagnosis of human DS because it does not provide a comparison of facial emotions with traditional methods for diagnosing disease symptoms.

The system and method for the diagnosis of neurological disorders was chosen as the prototype (US9715622B2 A61B5 / 00; A61B5 / 11; A61B5 / 16). This system uses TA videos for the diagnosis of neurological disorders (including DS diagnosis), which are compared with sample videos previously accumulated and stored in a database. This system can be operated remotely or used locally, for self-monitoring without medical supervision. The system consists of a video module, a video processing module, a diagnostic body selection module, and training and testing modules. The video module captures one or more videos when the TA is involved in various activities. The video is filmed on a mobile phone, tablet, camera, or any other device. When one or more videos are captured, they are transferred to the video processing module. Sample videos consist of a variety of emotions such as happy, sad, disgusted, surprised, angry, and more. All recordings of movements and emotions are compared with video data pre-accumulated and stored in the training and testing modules. TA monitoring results are passed on to nursing staff or used for TA training. The main disadvantage of the chosen prototype is that this system does not identify a specific neurological disorder and its severity, because an excessive number of variables that are characteristic of more than one neurological disorder are studied. There is no database about DS in the system, so they cannot be diagnosed.

The object of the invention is to create a device - a system for detecting human DS, using sensory evaluation and neuropsychiatric questionnaires, as well as the results of computer analysis of facial emotions of subjects. The device-based system is intended for psychiatrists, general practitioners and persons with psychological and / or psychiatric problems.

A patented system for the early diagnosis of human depression, comprising: a uniformly integrated information and registration unit 1, a survey form block 2, a survey form display device 3, a facial filming device 4, a question recording unit 5, facial emotions and answers analysis unit 6, file storage 7.

A patented system for the early diagnosis of human depression, in which block 2 of the survey forms contains sensory taste names and corresponding food products; forms of sensory evaluation of taste; dietary habits questionnaire; Depression Symptoms Questionnaire, preferably the Montgomery and Asberg Depression Assessment Questionnaire.

Patented system for early diagnosis of human depression, which is digitized in the files of the subjects 7: expressions of the subject's facial emotions, answers to the sensory forms of taste names and corresponding food products, sensory evaluations of tastes scores, answers to the questionnaire of eating habits, answers to the depression symptoms questionnaire .

The essence of the invention is that the numerical values of facial emotions of the TA responding to the questions are compared with the numerical values of facial emotions of groups of healthy and sick DS persons previously recorded and stored in the file repository. The system determines the degree of depressive disorder based on the diagnoses made by psychiatrists using the Montgomery and Asberg Depression Assessment Questionnaire.

A block diagram of a patented human early depression diagnosis system is shown in FIG. 1.

The system consists of:

subject information and registration block -1;

block of survey forms - 2;

survey form demonstration tool - 3;

face filming device - 4;

question recording block - 5;

facial emotion and response analysis block - 6;

file storage - 7.

The early diagnosis system for human depression works as follows:

Unit 1 is activated, which instructs and registers the subject using the screen 3 of the survey form display device, then turns on the survey form block 2 and the video device 4. Block 2 sends sensory taste names to the survey form display device (screen) 3 at set intervals. forms of compliant foods, forms of taste sensory scoring, and questionnaires on eating habits and depressive symptoms. TA answers the submitted forms and questions. TA creates emotions filmed by device 4; TA facial emotional expressions in response to forms and questionnaires are recorded by block 5. Upon completion of the survey, block 5 sends a video recording to block 6, which expresses facial emotions (neutral, happy, sad, angry, surprised, scared, disgusted, contempt) in numbers from 0 to 1. Block 6 uses facial emotion assessment software such as FaceReader (Noldus Information Technology, Wageningen, The Netherlands) for this purpose. Block 6 also records TA audio recordings, duration of responses, sensory rating scale scores, responses to questionnaires on eating habits and depressive symptoms. Block 6 directs the TA results to the file store 7. In the store 7, the files can be sorted by TA age, gender, numerical values of emotional expressions, and DS degree. The system concludes on the emotional expressions of the TA face by comparing the digitized recordings of the TA face emotions with the data of analogous settings in the file store 7. The severity of DS is determined from the smallest differences between the analogous data of the nearest group of TA. At the end, the early diagnosis system for human depression in the survey form display tool (screen) 3 provides the subject with a conclusion about the results of the detection.

Examples of patented human depression early diagnosis device system operation.

example

Block 1 TA instructs and registers using the survey form display screen 3. The TA reads the setup instructions and turns on the survey form block 2 and the video device 4. Block 2 displays “SURF” on screen 3, with the caption: “Look at the screen and imagine that you eat a product of this taste. Say it out loud orally about what product you are thinking of. Rate how you like this taste (from 1 - very dislike to 10 - very like) ". After 1 minute, if TA does not tell you what product you are thinking of, you will be asked to select one of the 5 similarly tasting product names displayed with the caption "Say the name of the selected product orally and rate that taste". Setting time up to 2 min. TA presses the “Continue.

Next, from the survey forms and questionnaire block 2, the notes “TOGETHER”, “SWEET”, “ACID”, “NEUTRAL” are sent, which are displayed on the screen 3 with notes analogous to the first taste. Setting time after 2 min.

Next, a questionnaire on eating habits, a questionnaire on depressive symptoms, such as the Montgomery and Asberg Depression Assessment Questionnaire, are sent from Block 2 of the survey forms and questionnaires.

All video, audio, text, duration video recordings of TA answers to the questions are sent to the answer recording unit 5 and the facial emotion analysis unit 6.

Block 6 digitizes the facial expressions and answers to the questions and, together with the registration form, directs them to the file repository 7.

The Early Diagnostic System for Human Depression draws conclusions about TA facial emotional expressions by comparing digitized TA facial emotion records with data from analogous settings in the file repository 7. At the end, the system provides the subject with a conclusion on the results of the determination in a survey form display (screen) 3.

The conclusion states: "No symptoms of depressive disorder were found"; or “Signs (symptoms) of a depressive disorder have been found. It is recommended to consult a physician ”or“ It is recommended to repeat this study ”.

example

The human early depression diagnostic system can be accessed remotely. To do this, it is necessary to: connect to the information and registration unit 1 of the system subject, have a means of displaying the survey forms (screen) 3 and a facial video device 4 (for example, either a computer or a mobile means of communication). The TA reads the setup instruction received from block 1, turns on the facial filming device, further requests the system to turn on block 2 of the survey forms, and then proceeds as described in Example 1. The facial video recording is sent by the TA computer or mobile device via a wired or wireless network adapter to the system's answer recording unit 5 or directly to the facial emotion and answer analysis unit 6.

Block 6 digitizes facial expressions and, together with the registration form, directs them to the file store 7. The human depression early diagnosis system draws conclusions about the TA face emotional expressions by comparing the TA face emotion records with the data in the file store 7. At the end, the device sends the conclusion and recommendation to the TA PC or mobile phone.

The authors performed comparative studies of the patented "Early Diagnostic System for Human Depression" in the following order:

(a) the emotional expressions of all TA faces were filmed in accordance with the first example;

(b) TA's mental health status was assessed by psychiatrists using a structured 'Montgomery and Asberg Depression Assessment Questionnaire';

c) TA is divided into the following groups: TA without DS (0-6 points); TA patients £ 20 points); TA with early DS symptoms (7-19 points);

d) the average numerical values of facial emotional expressions of different TA groups were compared.

Mean numerical values were found to differ:

non-DS and DS TA - 80% of cases;

TA in patients without DS and with symptoms of DS - 60%;

TA in patients with DS and symptoms of DS - 45%;

Facial emotions “neutral”, “happy” and “sad” make up the main part of about 0.75 of them, while the other 5 emotions make up only 0.25 of them;

those with DS TA facial emotions are “sad” and “scared” higher, and “happy” less than healthy, i.e., not with DS TA.

A patented early diagnosis system for human depression is designed for the early diagnosis of human DS based on the subject's emotional response to different food taste characteristics, and according to the food acceptance questionnaire, and the evaluation of different food taste characteristics. The patented system compares the emotional expressions of the TA face with the accumulated mean values of the results of analogous studies performed in healthy and sick DS. the device allows a quick, but only approximate, determination of whether the symptoms of DS occur at the time of the examination, and if they are detected, it is recommended that the TA seek medical attention. The reliability of the findings and recommendations of this newly developed “Early Diagnostic System for Human Depression” depends on the number of similar studies accumulated in data repositories. Conclusions and recommendations become more accurate as the number of TA cases investigated increases in the case repository 7.
