Description

Technical Field

[0001] The present invention relates to the field of smart medical technology, in particular to the field of transcranial magnetic stimulation, and specifically to a processing method, device, processor and computer-readable storage medium thereof for implementing TMS treatment for mood disorders and anxiety disorders based on emotion induction. Background Art

[0002] Transcranial magnetic stimulation (TMS) is a common neuromodulatory method for treating mood disorders and anxiety disorders, but its efficacy is average. Mood disorders and anxiety disorders are emotion-dependent mood disorders, and conventional TMS treatment modes are all performed in a resting state, ignoring the patient's neural responses under different emotions. The way to improve the efficacy of TMS is to treat the patient in a state of emotional induction through external stimulation. Currently, there is a lack of an objective, accurate and self-feedback system for individualized TMS treatment of patients with mood disorders and anxiety disorders under emotion-induced conditions.

[0003] Currently, the existing personalized TMS treatment method uses magnetic resonance imaging to extract the patient's resting brain structure and functional characteristics for target calculation. The most common target calculation method uses functional connectivity and structural connectivity using the subgenual anterior cingulate gyrus as a seed point to identify coupling targets located in the dorsolateral prefrontal cortex of the left hemisphere and then uses high-frequency transcranial magnetic stimulation for treatment. The main problem with this method is that it cannot effectively distinguish between patients with MDD (major depressive disorder) and healthy controls in the resting state. The core symptom of MDD is mood disturbance. This clinical characteristic suggests that identifying personalized treatment targets and performing TMS treatment in the context of specific emotions (such as sadness, happiness) or transitions between emotions can achieve better results.

[0004] Based on this, it is necessary to propose an improvement plan to overcome the defects and shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a processing method, device, processor and computer-readable storage medium thereof for TMS treatment of mood disorders and anxiety disorders based on emotion induction.

[0006] To achieve the above objectives, the present invention provides a method, device, processor, and computer-readable storage medium for TMS treatment of mood disorders and anxiety disorders based on emotion induction as follows:

[0007] The main feature of the method for TMS treatment of mood disorders and anxiety disorders based on emotion induction is that the method comprises the following steps:

[0008] (1) Conduct a clinical assessment of the patient's mental health before treatment;

[0009] (2) Conduct brain MRI examinations on patients in an emotionally induced state;

[0010] (3) Prioritize the selected individualized targets based on the patient's clinical assessment and the degree of abnormal brain functional activity under emotion-induced stimulation;

[0011] (4) Develop a TMS treatment plan for emotion-induced situations based on the order of target priority;

[0012] (5) Conduct short-term treatment evaluation and use efficacy prediction models to make long-term predictions of the remaining treatment trajectory;

[0013] (6) After the treatment is completed, the treatment trajectory will be fed back to the local database and a post-treatment clinical evaluation will be conducted.

[0014] Preferably, the step (1) is to perform basic emotional stimulation and complex emotional stimulation on the patient before treatment, specifically including:

[0015] (1.1) Develop video elements targeting basic emotions, including neutral emotion, sad emotion, and happy emotion;

[0016] (1.2) Based on the mean and variance of the evaluation dimensions, social attributes, and scope of application of different emotional materials, the basic emotional stimulus materials were combined in the order of no clear emotion, negative emotion, positive emotion, and distraction task. The distraction task material was to determine whether a calculation equation was correct within a limited time.

[0017] (1.3) Complex emotional materials use multiple videos of preset lengths, each of which contains a social plot with emotional fluctuations and plot twists;

[0018] (1.4) Associate each of the above elemental materials with emotional valence and arousal scores, and event attribute scores, and establish a database to manage the material fragments and their corresponding scores and attributes for subsequent clinical assessment of the patient's mental and psychological state before treatment.

[0019] Preferably, the individualized targets in step (3) include: the frontal lobe under negative emotions, the frontal lobe under positive emotions, the parietal lobe, and the temporoparietal junction, and are prioritized according to the following method:

[0020] (3.1) Perform head motion detection and removal, noise signal removal, time series high-pass filtering, image spatial registration, and linear regression analysis on the acquired emotion-induced brain functional images to obtain brain activation maps under various emotional situations;

[0021] (3.2) Using standard brain mapping, extract activation map data of the subjects' emotion processing-related brain regions, including at least the subgenual anterior cingulate gyrus, medial prefrontal cortex, precuneus, dorsolateral prefrontal cortex, temporoparietal junction, and supplementary motor area;

[0022] (3.3) Following the above process, obtain activation map data for the above brain regions from a healthy reference group, establish a normative model for the average activation level of each brain region in each context, and fit its probability distribution parameters, including but not limited to center location and standard deviation;

[0023] (3.4) For each patient's average activation level in each brain region in each situation, compare it with the distribution of the healthy reference group obtained in step (3.3), and calculate the deviation Z as follows:

[0024] Z=[x-mu] / std;

[0025] Where x is the activation value of the patient's brain region, mu is the mean activation value of the healthy control brain region, and std is the standard deviation of the activation value of the healthy control brain region;

[0026] (3.5) Summarize the activation level deviations Z of all brain regions of the individual patient in all situations, and sort the absolute values of each deviation level Z from large to small. Record the sorting and the corresponding brain regions and activation situations to complete the priority sorting process.

[0027] Preferably, the step (4) is specifically as follows:

[0028] Several brain regions and corresponding situations that rank high in the priority ranking are selected as intervention targets and corresponding situations. During the intervention, materials with the same situational attributes as the corresponding situation of the current target are first selected from the emotional situation material library for the patient to watch, hear, or experience, and then the TMS stimulation system is used to stimulate the corresponding target; the above process is repeated multiple times, with a rest interval between each time. Before the next situational stimulation begins, a distraction task is used to reduce the patient's previous emotional experience, and different brain regions and their corresponding situational attributes are selected from the newly obtained priority ranking table; the treatment course is set to within 10 days, and a brief symptom assessment is performed every day.

[0029] Preferably, the step (4) specifically includes the following steps:

[0030] (4.1) Select at least three stimulus materials with the same situational attribute labels for the current patient from the emotional situational material library to induce emotions;

[0031] (4.2) Select the stimulation target associated with the current stimulation material and choose the corresponding iTBS stimulation mode, 10 Hz rTMS stimulation mode, or 1 Hz rTMS mode for TMS modulation treatment;

[0032] (4.3) After the stimulation task is completed, the participants are tested for distraction by pressing a button to determine the correctness of a mathematical equation. After the distraction task is completed, the participants are tested for the next stimulus and the above steps are repeated.

[0033] (4.4) Based on the number of selected targets, arrange brain regulation treatment for all stimulation targets on the same day and perform them at intervals so that the emotional stimulation received before each TMS regulation has the same nature, so as to provide a precise TMS treatment plan.

[0034] Preferably, the step (5) specifically includes the following steps:

[0035] (5.1) When 1 / 4 and 1 / 2 of the treatment is completed, the mid-term HAMD score or PHQ9 self-assessment score will be performed respectively;

[0036] (5.2) Using the treatment baseline as the origin and the 1 / 4 and 1 / 2 mid-term assessments as the midpoints of the pathway, the expected range of efficacy was plotted based on the improvement rate of the mid-term efficacy estimated by the linear mixed model, and the expected efficacy was projected onto the expected efficacy according to the 95% CI range;

[0037] (5.3) If the predicted range of the final therapeutic effect based on the HAMD score reduction rate at the treatment start point, 1 / 4, and 1 / 2 projections contains a 50% score reduction rate of less than 5%, the treatment benefit is judged to be poor, and the top-ranked target is removed from the treatment plan and replaced with the highest-ranked target among the alternative targets;

[0038] (5.4) After the treatment is completed, the treatment trajectory is archived and the parameter estimates of the linear mixed model for estimating the mid-term efficacy are optimized.

[0039] The device for implementing TMS treatment for mood disorders and anxiety disorders under emotion induction has the following main features:

[0040] a processor configured to execute computer-executable instructions;

[0041] A memory stores one or more computer-executable instructions, which, when executed by the processor, implement the steps of the method for TMS treatment of mood disorders and anxiety disorders under emotion induction.

[0042] The main feature of the processor for implementing TMS treatment for mood disorders and anxiety disorders under emotion induction is that the processor is configured to execute computer-executable instructions. When the computer-executable instructions are executed by the processor, the steps of the method for implementing TMS treatment for mood disorders and anxiety disorders under emotion induction are implemented.

[0043] The main feature of this computer-readable storage medium is that it stores a computer program, which can be executed by a processor to implement the steps of the method for TMS treatment of mood disorders and anxiety disorders under emotion induction.

[0044] The processing method, device, processor and computer-readable storage medium of the present invention for TMS treatment of mood disorders and anxiety disorders based on emotion induction can effectively show, through the situational stimulation library and situational brain function imaging, that significant differences can be intuitively seen between the activities of different brain regions of patients and the healthy control group in different situations, and the direction of the difference is related to the situation. It also effectively illustrates the effectiveness of situational stimulation materials and the effectiveness of situational brain function imaging in the selection of individualized target regulation targets, and has relatively significant application value.

[0049] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0050] Before describing in detail embodiments according to the present invention, it should be noted that, hereinafter, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, whereby a process, method, article, or apparatus comprising a list of elements includes not only those elements, but also other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0051] See also Figure 1 As shown, the method for TMS treatment of mood disorders and anxiety disorders based on emotion induction includes the following steps:

[0052] (1) Conduct a clinical assessment of the patient's mental health before treatment;

[0053] (2) Conduct brain MRI examinations on patients in an emotionally induced state;

[0054] (3) Prioritize the selected individualized targets based on the patient's clinical assessment and the degree of abnormal brain functional activity under emotion-induced stimulation;

[0055] (4) Develop a TMS treatment plan for emotion-induced situations based on the order of target priority;

[0056] (5) Conduct short-term treatment evaluation and use efficacy prediction models to make long-term predictions of the remaining treatment trajectory;

[0057] (6) After the treatment is completed, the treatment trajectory will be fed back to the local database and a post-treatment clinical evaluation will be conducted.

[0058] As a preferred embodiment of the present invention, the step (1) is to perform basic emotional stimulation and complex emotional stimulation on the patient before treatment, specifically including:

[0059] (1.1) Develop video elements targeting basic emotions, including neutral emotion, sad emotion, and happy emotion;

[0060] (1.2) Based on the mean and variance of the evaluation dimensions, social attributes, and scope of application of different emotional materials, the basic emotional stimulus materials were combined in the order of no clear emotion, negative emotion, positive emotion, and distraction task. The distraction task material was to determine whether a calculation equation was correct within a limited time.

[0061] (1.3) Complex emotional materials use multiple videos of preset lengths, each of which contains a social plot with emotional fluctuations and plot twists;

[0062] (1.4) Associate each of the above elemental materials with emotional valence and arousal scores, and event attribute scores, and establish a database to manage the material fragments and their corresponding scores and attributes for subsequent clinical assessment of the patient's mental and psychological state before treatment.

[0063] As a preferred embodiment of the present invention, the individualized targets in step (3) include: the frontal lobe under negative emotions, the frontal lobe under positive emotions, the parietal lobe, and the temporoparietal junction, and are prioritized according to the following method:

[0064] (3.1) Perform head motion detection and removal, noise signal removal, time series high-pass filtering, image spatial registration, and linear regression analysis on the acquired emotion-induced brain functional images to obtain brain activation maps under various emotional situations;

[0065] (3.2) Using standard brain mapping, extract activation map data of the subjects' emotion processing-related brain regions, including at least the subgenual anterior cingulate gyrus, medial prefrontal cortex, precuneus, dorsolateral prefrontal cortex, temporoparietal junction, and supplementary motor area;

[0066] (3.3) Following the above process, obtain activation map data for the above brain regions from a healthy reference group, establish a normative model for the average activation level of each brain region in each context, and fit its probability distribution parameters, including but not limited to center location and standard deviation;

[0067] (3.4) For each patient's average activation level in each brain region in each situation, compare it with the distribution of the healthy reference group obtained in step (3.3), and calculate the deviation Z as follows:

[0068] Z=[x-mu] / std;

[0069] Where x is the activation value of the patient's brain region, mu is the mean activation value of the healthy control brain region, and std is the standard deviation of the activation value of the healthy control brain region;

[0070] (3.5) Summarize the activation level deviations Z of all brain regions of the individual patient in all situations, and sort the absolute values of each deviation level Z from large to small. Record the sorting and the corresponding brain regions and activation situations to complete the priority sorting process.

[0071] As a preferred embodiment of the present invention, the step (4) is specifically as follows:

[0072] Several brain regions and corresponding situations that rank high in the priority ranking are selected as intervention targets and corresponding situations. During the intervention, materials with the same situational attributes as the corresponding situation of the current target are first selected from the emotional situation material library for the patient to watch, hear, or experience, and then the TMS stimulation system is used to stimulate the corresponding target; the above process is repeated multiple times, with a rest interval between each time. Before the next situational stimulation begins, a distraction task is used to reduce the patient's previous emotional experience, and different brain regions and their corresponding situational attributes are selected from the newly obtained priority ranking table; the treatment course is set to within 10 days, and a brief symptom assessment is performed every day.

[0073] As a preferred embodiment of the present invention, the step (4) specifically includes the following steps:

[0074] (4.1) Select at least three stimulus materials with the same situational attribute labels for the current patient from the emotional situational material library to induce emotions;

[0075] (4.2) Select the stimulation target associated with the current stimulation material and choose the corresponding iTBS stimulation mode, 10 Hz rTMS stimulation mode, or 1 Hz rTMS mode for TMS modulation treatment;

[0076] (4.3) After the stimulation task is completed, the participants are tested for distraction by pressing a button to determine the correctness of a mathematical equation. After the distraction task is completed, the participants are tested for the next stimulus and the above steps are repeated.

[0077] (4.4) Based on the number of selected targets, arrange brain regulation treatment for all stimulation targets on the same day and perform them at intervals so that the emotional stimulation received before each TMS regulation has the same nature, so as to provide a precise TMS treatment plan.

[0078] As a preferred embodiment of the present invention, the step (5) specifically includes the following steps:

[0079] (5.1) When 1 / 4 and 1 / 2 of the treatment is completed, the mid-term HAMD score or PHQ9 self-assessment score will be performed respectively;

[0080] (5.2) Using the treatment baseline as the origin and the 1 / 4 and 1 / 2 mid-term assessments as the midpoints of the pathway, the expected range of efficacy was plotted based on the improvement rate of the mid-term efficacy estimated by the linear mixed model, and the expected efficacy was projected onto the expected efficacy according to the 95% CI range;

[0081] (5.3) If the predicted range of the final therapeutic effect based on the HAMD score reduction rate at the treatment start point, 1 / 4, and 1 / 2 projections contains a 50% score reduction rate of less than 5%, the treatment benefit is judged to be poor, and the top-ranked target is removed from the treatment plan and replaced with the highest-ranked target among the alternative targets;

[0082] (5.4) After the treatment is completed, the treatment trajectory is archived and the parameter estimates of the linear mixed model for estimating the mid-term efficacy are optimized.

[0083] In practical application, this technical solution divides the design of situational materials into two categories: basic emotions and complex emotions. The specific processing flow is as follows:

[0084] 1. The basic emotion materials consist of three types: no clear emotion, sadness, and happiness. Each segment is approximately 30 seconds long. The selected materials are organized and numbered, and the basic data is stored. To simulate the psychological process of emotional fluctuations and transitions in real life, based on the basic emotion materials, the elements are combined into overall stimulus materials according to the mean and variance of each dimension, social attributes, and scope of application of the different emotion materials in the following order: 1 → 2 → 3 → 4 → 1 → 2 → 3 → 4 → 1 → 2 → 3 → 4, where the numbers represent: 1 - no clear emotion, 2 - negative emotion, 3 - positive emotion, and 4 - distraction task. The distraction task involves determining whether a calculation equation is correct within a limited time.

[0085] 2. Complex emotion materials utilize multiple videos ranging in length from 30 seconds to 2 minutes and 30 seconds. Each video (elementary material) depicts a social scenario characterized by emotional fluctuations and plot twists. Unlike basic emotion elemental materials, complex emotion materials are composed of distinct character stories. Each elemental material exhibits relative integrity and coherence, offering advantages in terms of emotional arousal and content engagement. These materials also include more complex emotions such as sympathy, emotion, anxiety, and resentment. The emotional material library consists of multiple versions of the aforementioned situational materials, with each elemental material associated with an emotional valence and arousal score, as well as an event attribute score. A database is established to manage these material segments and their corresponding scores and attributes.

[0086] Regarding the calculation method of individualized brain function regulation targets in emotional contexts, this technical solution specifically includes the following processing steps:

[0087] 1. Based on the emotion-evoking video material in the video library and its second-by-second negative, neutral, and positive emotion evaluation labels, we established an individual-level general linear model (Y = BX + A + E). Here, Y represents the true signal of each brain region, X represents the vector resulting from the convolution of the negative, neutral, and positive emotion coordinates defined by the emotion response curve with the blood oxygen dynamics function, E represents the computational error, A represents the intercept, representing the baseline activation level, and B represents the regression coefficient vector, indicating the linear relationship between X and Y. This represents the brain activation level in each emotional context, which can be expressed as [b1, b2, b3, b4…]. Here, b1 represents the negative emotion response parameter, b2 represents the neutral emotion response parameter, b3 represents the positive emotion response parameter, and b4 and subsequent coefficients represent the contribution of the control variables. Let b1-b2 represent the negative emotion brain activation pattern, and b3-b2 represent the positive emotion brain activation pattern. A one-sample T-test was used to determine whether b1-b2 or b3-b2 was significantly different from zero, defining the brain activation criterion.

[0088] 2. Construct a norm-referenced model of brain function activation in emotional situations for at least 50 healthy individuals to characterize the activation characteristics and population variation within this population. Target brain regions involved in the following steps include, but are not limited to, the precuneus, subgenual anterior cingulate gyrus, medial prefrontal cortex, supplementary motor area, motor area, visual cortex, and right temporoparietal junction.

[0089] In practical applications, the specific method of constructing a norm-referenced model of brain function activation in emotional situations in this technical solution is as follows:

[0090] 1.1. Extract masks for marking target brain regions from standard brain atlases.

[0091] 1.2 On the mask, dilate 5 voxels in each direction.

[0092] 1.3. For each subject's fMRI data, after preprocessing (including at least motion correction, noise removal, and registration with a standard brain atlas), use the mask generated in Step 1.2 to extract the time series signal of the target brain region. This is represented by the matrix Di, which consists of T rows (number of time points) and V columns (number of voxels), where i represents the subject's sequence number.

[0093] 1.4. For Di and Dj (i = 2n, j = 2n+1, n = 0…floor(nsubj / 2), where floor(nsubj / 2) is the number of subjects rounded down to 1 / 2), perform the following calculations (steps ad are part of the procustean transformation):

[0094] a) Calculate Di', where each column is: dik'= dik – mean(dik); Dj', where each column is: djk'= djk –mean(djk), k = 1,2, …,V; each column of Di' represents the normalized representation of the time series of each voxel of subject i, and the mean of the time series is 0.

[0095] b) Calculate the singular value decomposition: USV T = Di'(Dj') T , where U and V are orthogonal matrices, S is a diagonal matrix; S is the eigenvalue of the projection matrix of the data of subject i to j.

[0096] c) Calculate R = UV T ; R represents the rotation transformation of the data from subject i to subject j.

[0097] d) Calculate c = tr(S) / tr((Di') T Di'), where tr represents the trace of the matrix; c represents the scaling coefficient in the spatial transformation from subject i to subject j.

[0098] e) Calculate Dij = cRDj'+1 Tby1 mean(di) T , where 1 Tby1 is a T-dimensional column vector with all elements set to 1; Dij represents the data after the procrustian space transformation of the data matrix of subject i to the data matrix of subject j.

[0099] f) Exchange Di and Dj, repeat steps ae to obtain Dji.

[0100] g) Average Dij and Dji to obtain Di+j.

[0101] 1.5. For each pair of subjects Di and Dj, calculate multiple Di+j and iterate step 1.4 until a unique Di+j is obtained. The final unique Di+j is recorded as Dtemplate. Dtemplate is the average data matrix of all subjects after the mutual procrustian transformation.

[0102] 1.6. Use the time series signals Di and Dtemplate of the target brain region for each subject as the inputs of step 1.4 and perform the calculations in steps 1.4a to 1.4d to obtain ci and Ri, where ci and Ri represent the scaling and selection transformations of the data matrix of subject i after the procrustian transformation of Dtemplate.

[0103] 1.7. For subject i, calculate the correlation matrix of the average time series between the target brain region and each other brain region, and obtain the correlation coefficient matrix Ei, which contains P rows and V columns, where P is the number of other brain regions other than the target brain region, and V is the number of voxels in the target brain region.

[0104] 1.8. Replace Di and Dj in step 1.4 with Ei and Ej (i = 2n, j = 2n+1, n = 0……floor(nsubj / 2), where floor(nsubj / 2) is the floor of half of the number of subjects), and perform all calculation steps of step 1.4.

[0105] 1.9. For the multiple Di+j obtained by calculating for each pair of subjects Ei, Ej, iteratively perform step 1.4 until a unique Ei+j is obtained, and denote the finally obtained unique Ei+j as Etemplate; Etemplate represents the average data matrix after the correlation matrices of all subjects are subjected to procrustian transformation with each other.

[0106] 1.10. Take the time series signal Ei of the target brain region of each subject and Etemplate as the input of step 1.4, and perform the calculations of 1.4a to 1.4d to obtain ci’ and Ri’; ci and Ri respectively represent the scaling and selection transformation after the functional connectivity matrix of subject i is subjected to procrustian transformation towards Etemplate.

[0107] 1.11. For the data of each subject, calculate ; , where i represents the subject number, lamda is a constant, 0 < lamda < 1; cci and RRi respectively represent the weighted average of the transformation of subject i towards Dtemplate and Etempalte for scaling and rotation transformation.

[0108] 1.12. For the data of each subject, use a linear regression model to calculate the brain activation map related to each emotional situation condition, denoted as ACTi, where i represents the subject number, and ACTi is a matrix with m rows and V columns, where m is the number of situations and V is the number of voxels in the target brain region.

[0109] 1.13. For the data of each subject, calculate ACTi’, where for each column: ACTik’ = ACTik – mean(ACTik), k = 1,2, …,V; ACTi’ is the data of the activation map of subject i after normalization between situations, and the mean of each column is 0.

[0110] 1.14. For the data of each subject, calculate ACTi” is the activation map matrix of subject i after procrustian transformation by RRi and cci.

[0111] 1.15. For each row of ACTi”, calculate the mean and standard deviation of the corresponding column of ACTi” for all subjects and fit the distribution curve parameters Beta_v (mu, sigma, skew, kurtosis), where v represents the voxel number in the target brain region, v = 1…V, that is, this parameter set is fitted for each voxel v separately.

[0112] 2. Compare the activation levels of the patient's target brain area in various situations with the healthy population distribution curve of the corresponding target brain area obtained in step 1 to obtain a low-level value. The specific steps are as follows:

[0113] 2.1 After preprocessing the patient's target brain region (including at least head motion correction, noise signal removal, and registration with a standard brain atlas), use the mask generated in step 1.2 to extract the time series signal of the target brain region. This signal is represented by a matrix D, consisting of T rows (number of time points) and V columns (number of voxels). This matrix D is used as the input variable. Execute the calculation in step 1.6 to obtain c and R, where c and R represent the procrustian transformation of the patient's data D onto the reference group's data template D template.

[0114] 2.2 Calculate the correlation matrix between the average time series of the target brain region and the other brain regions, obtaining a correlation coefficient matrix E, consisting of P rows and V columns, where P is the number of other brain regions in addition to the target brain region, and V is the number of voxels in the target brain region. Using E as the input variable, perform the calculation in step 1.10 to obtain c' and R', where they represent the scaling and rotation transformations of the patient's data E onto the reference group's data template Etemplate using the procrustian transformation, respectively.

[0115] 2.3 Using c, R, c', R' obtained in steps 1.6 and 1.10 as input, perform step 1.11 to obtain cc, RR, which are the scale and rotation transformations after the procrustian transformation of D and E, respectively.

[0116] 2.4 Use a linear regression model to calculate the patient's brain activation map associated with each emotional situation. This map, denoted as ACT, is a matrix with m rows and V columns, where m is the number of situations and V is the number of voxels in the target brain region. Perform steps 1.13 and 1.14 as input variables to obtain the ACT.

[0117] 2.5 Based on the distribution parameters Beta_v (mu, sigma, skew, kurtosis) obtained in 1.15, calculate the percentile of each voxel in ACT' relative to Beta_v (v refers to the voxel corresponding to ACT'), and calculate: deviation value = |50-percentile|.

[0118] 2.6 Rank the deviation values of each target brain region obtained from the above calculations under various scenarios, select the top 1-3 target brain regions as individual stimulation targets, and store the direction of deviation from the reference group (higher, lower) and the scenario attributes that cause the maximum deviation values in these brain regions.

[0119] 2.7 If the stimulation target is located more than 3 cm away from the scalp or is unsuitable for TMS stimulation, it is considered a non-cortical stimulation target. In this case, the functional connectivity between the original target and the cerebral cortical region is calculated using the contextual stimulation time series data. The stimulatable location with the maximum positive functional connectivity value is selected as the indirect stimulation target corresponding to the original target.

[0120] like Figure 2 As shown in Figure 2, the individualized TMS treatment plan in emotional situations is as follows:

[0121] 1. Based on the individualized brain regulation targets and their corresponding situational attribute labels determined by the above method, select at least three stimulus materials with the same situational attribute labels from the above emotional material library.

[0122] 2. During the brain manipulation implementation phase, patients first watched a one-minute video of the contextual material. Immediately afterward, repetitive transcranial magnetic stimulation (RTMS) was initiated, targeting the target associated with the stimulus material and determined by the aforementioned calculations. Stimulation modes included iTBS (three 50Hz pulses per group, 2 minutes at 5Hz), 10Hz rTMS, and 1Hz rTMS. The specific stimulation mode was determined based on whether the patient's stimulation target activity was lower or higher than the reference population. The duration and timing of the stimulation could be customized to suit the specific stimulation mode.

[0123] 3. After a stimulation period ends (or after the subject rests), perform a 2-minute distraction task. This task involves pressing a button to determine the correctness of a mathematical equation. Immediately after the distraction task, the subject will be presented with the next stimulus and the above procedure repeated.

[0124] 4. Based on the number of selected targets, schedule brain manipulation sessions for all stimulation targets on the same day, spaced out, and pre-stimulated with contextual videos of the corresponding situations as described in step 2. This contextual library ensures that the emotional stimulation received before each TMS session is consistent, but not simply repeated.

[0125] like Figure 3 As shown, this technical solution is based on a method for optimizing individualized treatment plans based on short-term treatment response evaluation and treatment response trajectory, specifically including the following steps:

[0126] 1. A mid-term HAMD score or PHQ9 self-assessment score was performed after 1 / 4 and 1 / 2 of the treatment was completed.

[0127] 2. With the treatment baseline as the origin and the 1 / 4 and 1 / 2 mid-term assessments as the midpoints of the pathway, the expected range of efficacy was plotted based on the improvement rate of the mid-term efficacy estimated by the linear mixed model, and the expected efficacy was projected according to the 95% CI range.

[0128] 3. If the predicted range of the final efficacy based on the HAMD score reduction rate projected from the starting point, 1 / 4, and 1 / 2 of the treatment is less than 5% and includes a 50% score reduction rate, the treatment benefit is judged to be poor. In this case, the top-ranked target is removed from the treatment plan and replaced with the highest-ranked target among the alternative targets. For example, if the initial treatment uses the targets ranked 1, 2, or 3, then the targets ranked 2, 3, or 4 are used when the treatment benefit is poor.

[0129] 4. After treatment, the treatment trajectory was archived and the parameter estimates of the linear mixed model for estimating the mid-term efficacy were optimized.
