Description

  The present invention relates to a system that uses a computer to provide a problem for training to prevent the progression of dementia.

  Dementia refers to a condition in which intelligence that has once developed normally is reduced due to an acquired organic disorder of the brain. There are many known diseases that cause dementia, including Alzheimer-type dementia (AD), which is a progressive neurodegenerative disease. In Japan, four drugs are recognized as treatments for AD, but all are only symptomatic treatments. The details of the pathogenesis of neurodegenerative diseases are still unclear, but it is important to find them quickly and properly treat them before the nerve cells are damaged.

  Under these circumstances, various non-pharmacological treatments have been performed for dementia, and research has demonstrated the effects of preventing the onset and progression of dementia.

  On the other hand, as a tool for judging the degree of dementia of individual patients, the forgetfulness consultation program (MSP) (Patent Document 1), TDAS (Touch Panel Type Dementia Assessment) developed by Urakami, one of the inventors of the present application. Scale: touch panel type cognitive function evaluation method) (see Patent Document 2). According to this TDAS, the inspection can be easily performed in a short time using a touch panel computer, even if it is not a specialist. The evaluation items include nine items of “word recognition”, “verbal instruction”, “graphic recognition”, “conceptual understanding”, “name memory”, “registration”, “money calculation”, “tool understanding”, and “clock understanding”. Because it is performed in the form of voice and image interaction, it is possible to realize a noninvasive test with less subject stress.

The interface unit 25 may be a unit that performs communication in conformity with a communication standard such as 3G or LTE.

  The control unit 11 controls the overall operation of the dementia prevention device 1 in order to realize the functions described below. The control unit 11 includes a CPU and an MPU, and implements various functions by executing predetermined control programs (OS, application programs) stored in the data storage unit 30. The control program executed by the control unit 11 may be provided from a network through a communication line, or may be provided via a recording medium such as a CD-ROM. The function of the control unit 11 may be realized by cooperation of hardware and software, or may be realized only by dedicated hardware.

  The data storage unit 30 is a means for storing data and programs, and stores control programs executed by the control unit 11, various databases, and data. The data storage unit 30 is composed of, for example, a hard disk (HDD) or a semiconductor storage device (SSD). In the present embodiment, the data storage unit 30 stores a control program 31, a subject database 32, a question database 33, an answer result database 34, and a question data file 35. The various databases 32 to 34 and the problem data file 35 will be described later.

1.1 Grouping based on degree of dementia In this embodiment, subjects are grouped based on the progression level of dementia. And when the dementia prevention apparatus 1 presents a problem to a subject, the problem selected from the problem group linked | related with the group of subjects is shown with respect to the test subject. Hereinafter, the concept of grouping of subjects in the present embodiment will be described with reference to FIGS.

  The subjects are grouped based on predetermined conditions. Specifically, as shown in FIG. 2, in addition to the progression level of dementia, grouping is performed in consideration of the sex and age of the subject.

  That is, based on whether the subject is male or female, the age is less than 65 years old, 65 years old to 74 years old, 75 years old or higher, and the progression level of dementia (TDAS result) It is classified into groups.

  The progress level of dementia is determined based on, for example, the result of TDAS, that is, the total score of TDAS and / or the elapsed time (30 minutes or more) required for the answer. For example, when the TDAS score is 0-6, it is classified as "Normal", when it is 7-13, it is classified as "Preliminary", and when it is 14 points or more or the elapsed time is 30 minutes or more, it is classified as "Dementia". The

  By grouping on the basis of sex, age, and progression level of dementia, subjects are classified into 18 groups as shown in FIG. In this embodiment, a problem group is associated with each group of subjects. That is, a plurality of questions selected (determined) according to the progress level of subjects belonging to the group are assigned to each group of subjects.

  For example, a group of subjects (groups 01, 04, 07, 10, 13, 16) with a dementia progression level of “normal” (TDAS score of 6 points or less) may have intermediate problems (higher than basic problems). Problem). This is because when the progression level of dementia is “normal”, dementia cannot be confirmed or is extremely low, and therefore, it is sufficient to present a problem that stimulates the brain to prevent future onset.

  In addition, a beginner level problem is assigned to a group of subjects (group 02, 05, 08,...) Whose dementia progression level is “Preliminary” (TDAS score is 7 to 13 points). This beginner's problem level is set to an easier level than the intermediate level.

  In addition, the group of subjects (groups 03, 06, 09,...) Whose dementia progression level is “recognition certificate” (TDAS score is 14 points or more or answer time is 30 minutes or more) has a dementia progression level. A problem level is assigned that is easier than the problem level of a group of “reserve” subjects. Since the progression of dementia is more advanced than in the “reserve army”, presenting a problem at a level easier than that in the “reserve army” will not reduce the subject's willingness to tackle the problem. It is to make it. It should be noted that the problem level of the group of subjects whose dementia progression level is “dementia” may include a problem at the same level as the problem level presented to the “preliminary” subject.

  By grouping on the basis of four conditions: gender, age, degree of progression of dementia, and type of cognitive function impaired, subject's gender Different problems can be presented depending on the age, and the problem can be presented based on more detailed conditions.

  As described above, the dementia prevention apparatus 1 associates problems to be asked for each group of subjects, and can present problems according to the state of the subject (gender, age, degree of dementia). Yes. For example, if the subject is male, the age is less than 65 years, and the dementia progression level is normal (TDAS score is 6 points or less), the problem identified as belonging to group 01 and related to group 01 is selected And presented to the subject. This makes it possible to provide the subject with a problem that can be expected to be more effective in consideration of gender, age, and progression level of dementia.

1.2 Database Hereinafter, databases (DB) 32 to 34 managed by the dementia prevention apparatus 1 of the present embodiment will be described.

(1) Subject database FIG. 4 shows the format of the subject database 32. The subject database 32 is a database that manages personal information of subjects. The subject database 32 includes factors that are considered to be related to dementia such as subject ID, subject's name, date of birth, sex, age, educational history (educational history), customs, residential area, group, dementia progression level, and the like.

  “Subject ID” is identification information (ID) for individually identifying a subject. “Habit” is information indicating the presence and frequency of a subject's habits regarding alcohol consumption and tobacco smoking. The “residential area” is information indicating the type of the subject's residential area, and is information indicating, for example, “city”, “mountainous area”, “seaside”, and the like. “Group” is information indicating a group to which the subject belongs when the subject is grouped with respect to the degree of dementia based on a predetermined condition. This group will be described later.

  “Dementia progression level” is information indicating the progression level of the subject's dementia, and in this example, the result by TDAS (score of TDAS, answer time, what kind of problem is wrong, etc.) is used. In TDAS, questions for confirming figure recognition, concept understanding, name storage, orientation, calculation of money, tool understanding, watch understanding, etc. are presented, and subjects' answers to these questions are obtained. The dementia prevention apparatus 1 manages the answer results (the contents of answers, correct / incorrect, elapsed time, etc.) for those questions as “dementia progression level” for each subject. In addition, about the result of TDAS, you may manage not with the inside of the dementia prevention apparatus 1 but with an external server. In that case, the dementia prevention apparatus 1 should just access an external server as needed, and acquire those information.

  In addition, the subject database 32 stores information on whether or not there is an obstacle in figure recognition, concept understanding and / or money calculation for each subject. In addition to the above-mentioned items, the subject database 32 stores body-related information such as the subject's body type (slimy type, normal, obesity, etc.), presence / absence of exercise, frequency of driving, etc., blood pressure, medical history, etc. May be included.

(2) Problem database As described above, in this embodiment, the subjects are grouped according to the conditions of the subject (gender, age, progression level of dementia, impaired function), and the problem is determined according to the group of subjects. It is set. The problem database 33 is a database that associates each group with a problem group assigned to the group. FIG. 5 is a diagram illustrating the configuration of the problem database 33. For example, in the example of FIG. 5, problem 1, problem 2, problem 3,... Are assigned to group 01 for subjects whose sex is male and age is 65 or younger and dementia progression level is 6 or less. . Also, problem 1, problem 3, problem 5,... Are assigned to group 04 for subjects whose sex is male and whose age is between 65 and 75 and the dementia progression level is 6 or less.

  Thus, since each problem group 33 associates each group with a problem corresponding to the group, a problem that is assigned to each group by updating the problem database 33 (that is, a problem to be presented to the subject). Can be changed as appropriate.

  The contents of each problem are managed as a problem data file 35. The problem data file 35 includes information regarding individual problems. Specifically, the question data file 35 includes, for each question, in addition to image data for displaying the question, question type, answer time threshold, answer options, correct answer data, and the like. . The problem data file 35 manages each problem by distinguishing it with identification information (problem ID). "Problem type" is a problem that stimulates figure recognition, calculation, memory, executive function, orientation, etc. that is impaired by dementia, or reminiscence therapy, music that is known to be effective for dementia Information indicating the type of problem associated with therapy that stimulates cognitive functions, such as therapy, RO (Reality Orientation) therapy.

(3) Answer Result Database The answer result database 34 is a database that manages answer results for questions by subjects. The answer result database 34 manages the results of answering each subject for each question. FIG. 6 shows the format of the answer result database 34. The answer result database 34 includes information on a question ID, a subject ID, a group ID, an execution date and time of the question, an answer made to the question, a correct / incorrect result, and an elapsed time required for the answer.

  “Problem ID” is an ID for identifying a problem to be managed. “Subject” includes the subject ID of the subject who answered the question. “Group” is an ID of a group to which the subject belongs. The “implementation date” is information on the date and time when the problem was implemented. “Answer” is information indicating the content (option) of the answer made to the question. “Correct” is information indicating whether the answer to the problem is correct or incorrect. “Elapsed time” is the time required from problem presentation to answer.

2. Operation The operation of the dementia prevention apparatus 1 of the present embodiment will be described. In particular, the operation of the function of presenting a training problem for the purpose of preventing or improving the progression of dementia to the subject will be described with reference to the flowchart of FIG.

  When the dementia prevention device 1 is activated, the control unit 11 displays a menu screen as shown in FIG. When the “Mono-Tele” icon (dementia prevention training icon) is selected by the subject on this menu screen, the control unit 11 displays a screen for inputting the subject's ID and password on the display unit 17 (S11). .

  When the ID and password are input by the subject, the control unit 11 performs authentication based on them, and when the information is determined to be valid, the control unit 11 refers to the subject database 32 based on the subject ID, and The group to which it belongs is specified (S12).

  The control unit 11 refers to the problem database 33 and appropriately selects a predetermined number of problems from the problem group corresponding to the specified group of subjects (S13). Here, the predetermined number is set so as not to be a burden on the subject. For example, the number of problems is set such that the training time is within 10 minutes.

  Here, when the subject's dementia progression level is “reserve army”, the problem is further distinguished according to the subject's dementia content. That is, as shown in FIG. 2, when the subject's dementia progression level is “reserve army”, the problem that the subject chooses depending on whether there is an obstacle in figure recognition, concept understanding and / or calculation of money. More limited. In other words, if the subject has an obstacle in figure recognition, concept understanding, and / or money calculation, a problem other than calculation is selected. On the other hand, if there is no disability for these, select problems related to cognitive stimulation, reminiscence therapy, music & RO therapy from the same group of problems. Since the problem data file 35 manages the “type of problem” for each problem, referring to this information allows the control unit 11 to determine whether the problem is a calculation problem, cognitive stimulation, reminiscence therapy Can determine if it is related to music & RO therapy. In addition, the subject database 32 stores information on whether or not there is an obstacle in figure recognition, concept understanding and / or money calculation for each subject. Therefore, by referring to the information in the subject database 32 and the “problem type” in the problem data file 35, the control unit 11 can change the content of the subject's dementia from the problem group corresponding to the subject group. You can select the problem that suits you.

  The control unit 11 displays the selected questions one by one on the display unit 17 and receives the answers of the subject (S14). When presenting a problem, voice guidance may be output along with image display.

  The example of the image of the problem for the dementia prevention training shown with respect to a test subject by the dementia prevention apparatus 1 of this embodiment is shown to FIG. 9A-9M.

9A to 9B show the problem of selecting different positions on the left and right photographs. The test subject answers by indicating the location that he / she thinks is different by touch or mouse. FIG. 9C shows a case where the answer is correct, and “◯” is displayed. 9D and 9E show the problem of searching for a certain feature in a photograph. The test subject answers by indicating a place where he / she thinks there is a certain feature by touch or a mouse.
9F and 9G are problems for training graphic recognition. In this example, training is performed on shape recognition of circles, triangles, and squares. FIG. 9H shows a case where an incorrect answer is made, and the word “Okay” is displayed. FIG. 9I is a problem for training numbers. FIG. 9J is a problem for training money calculations. 9K and 9L are problems relating to calculation. FIG. 9M is a problem related to name storage.

  Returning to FIG. 7, when there is an answer (selection of choice) from the subject, the control unit 11 determines correctness and displays the determination result on the display unit 17 (S 15). For example, in the case of a correct answer, “◯” is displayed as shown in FIG. 9C, and in the case of an incorrect answer, “OK” or “X” is displayed as shown in FIG. 9H.

  The above process is repeated until all the selected problems are presented (S14 to S16).

  When all the questions are presented and answered, the control unit 11 displays the answer results (the correct answer rate and answer time for each question) on the display unit 17 as shown in FIG. 10 (S17).

  Finally, the control unit 11 records (updates) the training result of the subject, that is, the answer result for each question, in the answer result database 34 (S18). That is, for each question, the control unit 11 records (updates) information such as elapsed time, right and wrong, and answers (options) selected by the subject in the answer result database 34.

  As mentioned above, according to the dementia prevention apparatus 1 of this embodiment, a test subject is divided into groups based on a predetermined condition, and the problem according to a group is provided. This makes it possible to present a problem that can be expected to be more effective depending on the condition of the subject.

  Furthermore, according to the dementia prevention apparatus 1 of the present embodiment, the answer results for the problem are accumulated in the answer result database 34. Therefore, by referring to the data accumulated in the answer result database 34 and the results of TDAS performed separately, it is possible to verify whether each subject's group has an effect on each question. Then, by updating the problem database 33 based on the verification result, it is possible to present a more appropriate problem according to the state of the subject to the subject.

  In the above example, the subjects were grouped based on gender, age, dementia progression level, and impaired function. However, the method of grouping subjects is not limited to this. For example, subjects may be grouped based only on the dementia progression level. Alternatively, subjects may be grouped based on the dementia progression level and sex or age. Alternatively, subjects may be grouped based on the dementia progression level and other subject conditions (habits, educational background, physique, etc.).

  Moreover, in said example, the various databases 33-34 and the data file 35 were demonstrated the example hold | maintained in the dementia prevention apparatus 1. FIG. However, these databases 33 to 34 and the data file 35 may be held in an external server. In that case, the dementia prevention apparatus 1 should just download those data from an external server as needed.

3. Confirmation of effect Using the above-described dementia prevention apparatus 1, two subjects who were actually judged to have dementia were trained (dementia prevention program), and the results were verified. In the training, grouping was performed based on each subject's attributes (gender, age, dementia progression level (TDAS score)), and problems corresponding to the group were presented to each subject. The verification results are shown below.
(1) Subject A
・ Gender: male ・ Age: 75 years old ・ Dementia progression level: dementia ・ TDAS score: 35 points ・ Degree of care: Need for long-term care 1
・ There was violent violence, anxiety, and poor emotional expression. Subject A with the above attributes was trained three times a week. 35 days after the start of training, I was less grumpy and smiled. In addition, 40 days later, they actively wanted to wash laundry, and 43 days later, they talked to the neighbors to try puzzles together. When TDAS was performed again after 45 days, it was 26 points and an improvement was seen. In training, the correct answer seems to have led to confidence. We received an opinion from the family that as a result of training for about a month and a half, smiles and motivation have improved.

(2) Subject B
・ Gender: Female ・ Age: 83 years ・ Dementia progression level: Dementia ・ TDAS score: 29 ・ Nursing care required: Need 1
・ Forgetfulness and face cannot be remembered Subject B with the above attributes was trained three times a week. 28 days after the training started, smiles came out. I'm also looking forward to training. When TDAS was performed again after 43 days, it was 17 points, and an improvement was seen. Whereas nothing was done before, after 51 days, it was confirmed that Subject B was washing the dishes himself and was positive. Also, I couldn't remember my face before, but after 64 days my neighbor is going to the day service, so there is a statement that I want to go together, and I can see that I remember my face Remarks were seen. I also look forward to day service with my neighbors. As a result of training for about two months from the family, I got the opinion that it became more lively, conversations increased, and became more active.

  As described above, the training using the dementia prevention device 1 performed on the subjects A and B shows improvement in the TDAS score (dementia progression level), and the less likely that it becomes unmotivated, Improvements were also confirmed in QOL (Quality Of Life), such as increased liveliness and increased conversation.

(Embodiment 2)
You may make it provide the training function (dementia prevention program) which the dementia prevention apparatus 1 demonstrated in Embodiment 1 provided through a network. For example, the system may be configured as follows.

  In FIG. 11, the structure of the dementia prevention system of this embodiment is shown. The dementia prevention system includes a dementia prevention program providing server 110 and an information terminal 50. The dementia prevention program providing server 110 and the information terminal 50 are connected to the network 100 and can communicate with each other via the network 100.

  The dementia prevention program providing server 110 is a server that provides the same function as the dementia prevention apparatus 1 described in the first embodiment, and has the same configuration as the dementia prevention apparatus 1. The information terminal 50 is a terminal such as a tablet terminal, a personal computer, or a smartphone. The dementia prevention program providing server 110 communicates with the information terminal 50 on the network 100 via the interface unit (25). The dementia prevention program providing server 110, the dementia data server 120, and the information terminal 50 are implemented with dedicated software (application program) for executing the functions described below.

  The information terminal 50 connects to the providing server 110 based on a specific URL. The dementia prevention program providing server 110 requests the information terminal 50 to input a subject ID and a password. When a subject ID and a password are input from the information terminal 50 by the subject, the dementia prevention program providing server 110 performs authentication according to the input subject ID and password.

  If the authentication is OK, the dementia prevention program providing server 110 identifies the subject from the subject ID, selects a training problem corresponding to the subject, and transmits data on the selected problem to the information terminal 50.

  The information terminal 50 displays the training problem on the display unit based on the received data, and advances the presentation of the problem according to the input of the subject (the process at this time is as described in the first embodiment). ).

  When the presentation / answer of all the questions is completed, the information terminal 50 transmits the result to the dementia prevention program providing server 110 via the network. The dementia prevention program providing server 110 updates the answer result database 34 based on the received result.

  According to the above configuration, it is not necessary to store the control program 31 and various databases 32 to 34 in the information terminal 50, and the dementia prevention program can be used anytime in an environment where it can be connected to the network. As a result, the convenience of the subject can be improved.

  The data accumulated in the answer result database 34 and the TDAS result are anonymized and then aggregated in a server (dementia data server) 120 on the network so that it can be provided to a predetermined user on the network. May be. As a result, many researchers can share and utilize data related to dementia, and it is expected that research in the field of dementia will be promoted.

(Summary)
