Description

The present invention relates to screening supporting 援Shi stem and screening support program for supporting the screening of such dementia and developmental disorders.

  Since early detection and treatment are important for cognitive dysfunction such as dementia, various testing methods for early detection have been developed. Among them, MMSE (Mini-Mental State Test) is a comprehensive cognitive function test mainly used to measure memory, computational power, linguistic ability, and orientation, and is widely used worldwide. . In TMT (Trail Making Test), TMT-A is used for checking attention duration and selection, visual search, visual motor coordination, etc., and TMT-B is the ability to convert and perform attention and concepts. It is used for checking. The Kana Hiroi test is used to check frontal functions and attention distribution ability. However, the TMT and Kana Hiroki tests are simple tasks, and the MMSE evaluation test does not want the subject to take the test because, for example, “What is the date of the month?” Tend.

  In order to solve such a problem, Patent Document 1 below proposes an inspection device that uses music to determine a test for dementia and forgetfulness and a level thereof. The apparatus of Patent Document 1 includes a storage unit that stores examination questions related to music, a voice output unit that outputs music, a display unit that displays an examination question, and a subject that answers the examination question. And an examination processing means for judging the symptom level of the subject's dementia or forgetfulness from the inputted answer.

  However, in the background art described in Patent Document 1, it is necessary for the examinee to see and confirm characters and pictures displayed on the inspection apparatus, and to further perform an operation such as inputting an answer using the input device. Therefore, it cannot be easily performed for a person whose visual acuity is weak or a person who is not good at performing an operation using the input means. In addition, there is a description that the determination result by the apparatus of Patent Document 1 and the results of the “Hasegawa-type simplified intelligence evaluation scale” and “overall diagnosis” are substantially the same (see paragraph 0054 above). It is unclear how much correlation there is because there is no disclosure of criteria for matching / mismatching.

The present invention focuses on the above points, and can also be used as a preliminary screening for undergoing a cognitive function evaluation test such as dementia or developmental disorder. to provide a screening support system及bis cleaning support program that can, it is an object thereof.

  Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

  <Outline of Screening Support> First, an outline when the present invention is used for screening of cognitive function evaluation of dementia will be described. The present invention divides one completed music piece into a plurality of phrases (sometimes corresponding to this divided phrase may be expressed as “sound cell”), and rearranges these divided phrases to complete the original music piece. Ask the subject to perform the task. Then, by acquiring log data of the work process until the task is achieved or until the task is abandoned, a known cognitive function evaluation test (for example, MMSE, TMT-A, TMT-B, Kana Hiroi test, etc.) Data for evaluation for estimating the result is calculated. Then, an analysis database indicating a correlation or significant difference between the cognitive function evaluation test data and the evaluation data is prepared in advance, and the cognitive function is referred to from the calculated evaluation data with reference to the analysis database. Estimating the evaluation test results can provide motivation for receiving a function evaluation test or the like. It may be used to estimate the degree of progression of dementia and the degree of improvement from the change over time of the results by having the task performed regularly.

  FIG. 1A shows a state where the music piece M is divided into a plurality of phrases and a state where the music piece M is rearranged to the original state. The music M used in the present invention may be any music as long as it is completed as a music, but from the viewpoint of use for screening of cognitive function, there is a music that anyone can know. preferable. Also, a song with lyrics can be enjoyed by singing the lyrics when actually performing a task. Therefore, in this embodiment, “hometown” is used as the song for the assignment. The upper side of FIG. 1A shows a state where “hometown” is divided into four phrases F1 to F4 and mixed. Phrase F1 corresponds to “Rabbit Oishika no Yama”, Phrase F2 corresponds to “Kubuna Tsuruka no Kawa”, Phrase F3 corresponds to “Yume is now going around”, and Phrase F4 corresponds to “Forgetfulness hometown” . The correct position of phrase F1 is the first position, the correct position of phrase F2 is the second position, the correct position of phrase F3 is the third position, and the correct position of phrase F4 is the fourth position. From the state in which the order of these phrases F1 to F4 is mixed, as shown by the arrow in FIG. 5A, the order of the correct positions, that is, the phrases F1 → F2 → F3 → F4 can be arranged correctly. Acquire log data of work performed by the subject.

  In the present invention, as shown in FIG. 1A, through the work of simply changing the order of default songs that have not been changed at all (hereinafter referred to as “serial task”). You may make it acquire log data, but you may make it perform a subject, mixing the phrase which added the variation to the music. For example, let the phrases F1def to F4def be as shown in FIG. 1B when the default music that has not been modified in the original music is divided into a plurality of phrases. Moreover, let the phrase F1v1-F4v1 be a phrase when the variation music which added the variation to the original music is divided | segmented into several phrases in the same position as the said default music, as shown in FIG.1 (B). Then, from the state where these phrases F1def to F4def and phrases F1v1 to F4v1 are mixed, the work of rearranging the phrases of the default song in the order of phrases F1def → F2def → F3def to F4def (hereinafter referred to as default when a modified phrase is added) Log data may be acquired through a process of rearranging phrases in the correct order (referred to as “matrix task”).

  One or more types of variation songs may be prepared for the default song (Def), but in this embodiment, three types of variation songs (Var1 to Var3) are prepared as shown in FIG. It was decided. FIG. 1C shows the number of the sound cell corresponding to each divided phrase when the default song and the variation song are each divided into four. For example, the first position sound cell of the default song is “10”, the second position sound cell is “20”, the third position sound cell is “30”, and the fourth position sound cell is “40”. It is. The same applies to the variation songs Var1 to Var3. A method for creating a variation song will be described in detail later.

  <System Configuration> Next, the overall configuration of the screening support system of the present embodiment will be described with reference to FIGS. As described above, the present invention uses the divided phrases obtained by dividing the completed musical piece into a plurality of phrases, and acquires log data of the rearrangement work process. A working tool corresponding to the divided phrase is required. FIG. 2 shows the overall configuration of a screening support system for realizing the present invention. As shown in the figure, the screening support system 10 of the present embodiment reproduces a phrase based on a plurality of sound cell blocks SB10 to SB40, a work board 20, and a subject's reproduction instruction, It is comprised by the log acquisition calculating device 60 which acquires the log data of a process.

  The sound cell blocks SB10 to SB40 are work blocks for the subject to rearrange on the work board 20, and each divided phrase when one piece of music is divided into a plurality of phrases. Corresponding identification information is attached. The sound cell blocks SB10 to SB40 in FIG. 2 are blocks corresponding to the divided phrases of the music that has not been modified from the original music, and are divided phrases F1 to F4 in FIG. 1 (A) or FIG. 1 (B). Correspond to the phrases F1def to F4def. The sound cell blocks SB10 to SB40 have identification information corresponding to the divided phrases assigned to each block. For example, since the sound cell block SB10 corresponds to the sound cell “10” in FIG. 1C, a two-dimensional barcode BA10 corresponding to the cell number is attached. The same applies to the other sound cell blocks SB20 to SB40.

  As shown in FIG. 1 (C), in this embodiment, three variations of phrases are prepared for the default divided phrase at each position, so the sound cell block is actually As shown in FIG. 3, 16 types of sound cell blocks SB10-13, sound cell blocks SB20-23, sound cell blocks SB30-33, and sound cell blocks SB40-43 are prepared. Note that the simple description of the sound cell block SB means that it is not specified as a specific sound cell block. Two-dimensional barcodes BA10 to 13, BA20 to 23, BA30 to 33, and BA40 to 43 corresponding to the corresponding cell numbers are attached to the 16 sound cell blocks, respectively. When it is simply expressed as a two-dimensional barcode BA, it means that it is not specified by a specific two-dimensional barcode.

  Next, on the work board 20, a plurality of set portions 22 to 28 for placing the sound cell blocks SB10 to SB 43 are formed in a line. In this embodiment, since one song is divided into four phrases, the number of the set portions 22 to 28 is four. However, the number of set portions can be increased or decreased as appropriate according to the number of divided songs. It is. Bar code readers 32-38 for reading the two-dimensional bar codes BA10-43 attached to the sound cell blocks SB10-43 are provided on the bottom surfaces of the set units 22-28. The work board 20 is provided with playback selection buttons 42 to 48 for selecting playback of a phrase corresponding to the sound cell block SB placed in the set units 22 to 28. Further, below these playback selection buttons 42 to 48, phrases corresponding to one or more sound cell blocks selected by the playback selection buttons 42 to 48 are sequentially input from the set unit 22 side to the set unit 28 side. A playback button 50 for continuous playback is provided. A stop button 52 for instructing to stop playback is provided next to the playback button 50. When the sound cell block SB is not placed at any position of the set units 22 to 28 or when reproduction is not selected, a click sound with a tempo that matches the position is reproduced, or Play back that position. The work board 20 is provided with a reset button 54 that is used when the task is re-executed from the beginning.

  The system configuration of the work board 20 is as shown in FIG. 3, the barcode readers 32 to 38 are provided in the reading unit 30, and the reproduction selection buttons 42 to 48, and the reproduction instruction unit 40 are provided. A play button 50 and a stop button 52 are provided. When the reproduction selection buttons 42 to 48 and the reproduction button 50 are pressed by the subject in question, the two-dimensional barcode of the sound cell block placed in the set portion of the reproduction designated portion is displayed on the barcode reader. The read information and the reproduction instruction are sent to the log acquisition arithmetic device 60 described later.

  Next, the log acquisition arithmetic device 60 will be described. The log acquisition arithmetic device 60 reproduces a phrase (voice output from the voice output unit 92 in FIG. 2) in response to an instruction from the work board 20. The log data until the task of rearranging the sound cell blocks SB10-43 is achieved or abandoned until the arrangement of the sound cell blocks SB10-43 on the work board 20 matches the default music before the division is described above. Acquired for each subject in the assignment. And the data for evaluation for estimating the test result of cognitive function evaluation of the screening object are calculated from the log data. Specific examples of log data and evaluation data will be described later.

  With reference to FIG. 3 as well, a specific system configuration of the log acquisition arithmetic device 60 will be described. The log acquisition arithmetic device 60 is mainly configured by a CPU 62, and includes a program memory 64, a data memory 80, and an audio output unit 92. , A display unit 94, an input unit 96, and the like. The program memory 64 is provided with a phrase reproduction program 66, a log acquisition calculation program 68, a determination program 70, and an output program 74. In the data memory 80, a phrase database 82, subject data 84, and an analysis database 90 are stored. The subject data 84 includes task log data 86 and evaluation data 88. In the analysis database 90, correlation / test data and the like are accumulated.

  When there is a reproduction instruction from the work board 20, the phrase reproduction program 66 is based on the identification information acquired by the barcode reader of the set portion of the position selected by the reproduction selection buttons 42 to 48. The 80 phrase database 82 is referred to. Then, the phrase data of the corresponding divided phrase is read out and reproduced by the audio output unit 92 in the designated reproduction mode. For example, when all the positions are selected by the playback selection buttons 42 to 48, all the corresponding phrases are continuously played back, and when any one or more positions are selected, the selected position is set. Only the corresponding phrases are played in order. In the case of continuous reproduction, composition processing or the like may be appropriately performed as necessary. In the phrase database 82, phrase data corresponding to each divided phrase (sound cells “10” to “43” in FIG. 1C) is accumulated, and each divided phrase and the sound cell blocks SB10 to SB43 are stored. The correspondence of the attached two-dimensional barcodes BA10 to BA43 is stored.

  Next, the log acquisition calculation program 68 in the program memory 64 acquires the task log data 86 until the serial task described in FIG. 1A or the matrix task described in FIG. 1B is achieved or abandoned. At the same time, the evaluation data 88 is calculated based on the task log data 86. FIG. 8 shows an example of the subject data 84. The details of the data in FIG. 8 will be described later. In FIG. 8, the portion surrounded by a dotted line is the task log data 86, and the portion surrounded by a one-dot chain line is the evaluation data 88. The task log data 86 and the evaluation data 88 are stored as the subject data 84 in the data memory 80.

  Next, the determination program 70 refers to the analysis database 90 of the data memory 80, estimates the result of the cognitive function evaluation test from the evaluation data 88 obtained by the log acquisition calculation program 68, and determines the cognitive function. Is what you do. In this example, the cognitive function evaluation test is a known cognitive function evaluation test (MMSE, etc.), and the determination of cognitive function is an approximate tendency of whether or not there is a high possibility of dementia. This does not necessarily indicate whether or not the patient has dementia. The analysis database 90 is prepared in advance based on data of a large number of subjects who have performed both the problem of the present invention and a known cognitive function evaluation test.

  As an example of analysis data such as correlation / test data included in the analysis database 90, FIG. 10 shows correlation data 90A indicating the correlation between the cognitive function evaluation of the subject who achieved the matrix task and the evaluation data. It is shown in the form of FIG. 11 also shows the correlation between attention, calculation (working memory ability), recall (recent memory ability), and evaluation data, which are subordinate items of MMSE, among the cognitive function evaluations of subjects who have achieved the matrix task. Correlation data 90B is shown in tabular form. The output program 74 displays the task log data 86, the evaluation data 88, the correlation data 90A, 90B, etc. on the display unit 94 in an arbitrary format such as a table or a graph individually or simultaneously as necessary. To do.

  <Creation of Variation Phrase> Next, the variation phrase used in this embodiment will be described. In this embodiment, the material of the sound cell for the serial task or the matrix task is “hometown” familiar to elderly people. “Furusato” is composed of 16 bars, and this is divided into phrases of every 4 bars, which are the default phrases corresponding to the four set portions 22 to 28 of the work board 20. These correspond to the sound cells “10”, “20”, “30”, and “40” shown in FIG. Next, three types of variations were created for the default, and the variation 1 (Var1), variation (Var2), and variation 3 (Var3) were arranged in descending order of musical change. The sound cells corresponding to Var1 are “11”, “21”, “31”, and “41”, respectively, and the sound cells corresponding to Var2 are “12”, “22”, “32”, and “42”, respectively. “,” And “13”, “23”, “33”, and “43”, respectively (see FIG. 1C). FIG. 6A shows an example of a score corresponding to sound cells “10”, “13”, “12”, and “11” in the first position. Note that examples of music corresponding to the second position to the fourth position are omitted, but variation phrases at these positions are also created by the same method as described below.

In creating the variation, the following rules were established so that the change in Var3 was very small compared to the default, Var2 was slightly larger than Va3, and Var1 was a significant change.
(1) Common to Var1 to Var3: It was decided not to deviate from the default (def) tonality. Do not transpose phrases or transpose phrases that span more than one measure. The maximum jumping pitch is 1 octave. The pitch of the first note and the phrase of the last two measures are not changed (see the score example in Fig. 6 (A)).
(2) Var3: The pitch of one place is changed per one sound cell (in this embodiment, one sound cell is composed of four bars) without changing the default (def) rhythm. At this time, a harmony sound is associated with a harmony sound, and a non-harmonic sound is associated with a non-harmonic sound. The first note does not change the note value (see Var3 in the score example in FIG. 6A).
(3) Var2 ... In addition to the above change of Var3, change the rhythm at one place. At this time, the unit of the note value to be changed is set to be equal to or greater than the minimum note value used in the original music. The first note does not change the note value (see Var2 in the score example in FIG. 6A).
(4) Var1 ... Creates a new phrase without changing the default chord. At that time, the minimum unit of the note value to be used is set to be equal to or greater than the minimum note value used in the original song, and the lyrics of the original song can be added without difficulty (Var1 in the example in FIG. 6 (A)). reference).

Next, for the variations created according to the rules (1) to (4) above, the phrase change rate was calculated by the following method.
(a) Phrase of the first position of each of the default and variations Var1 to Var3 is shown on a piano roll score with the vertical axis unit set to pitch (semitone) and the horizontal axis unit set to the minimum note value. (See FIG. 6B).
(b) Next, the pitches of the default phrases are all set to 1, and the absolute value of the pitch change amount given at the time of the variation is shown in a graph. This graph is shown in FIG. The maximum value of the pitch that the sound can take next is 1 octave, and the total is the maximum variable range of the phrase. The reason why the maximum value is 1 octave is that it is extremely rare for a phrase of a song to jump more than 1 octave, and the composition method may prohibit it.

(c) Next, a change in sound value on the horizontal axis is extracted from the graph of FIG. This graph is shown in FIG.
(d) The “hometown” used in this embodiment has a minimum note value composed of eighth notes and three quarters. In this case, the total number of note values per sound cell is 24, and the maximum variable range. 288. A value obtained by dividing the changed sound value number by the total sound value number was defined as a sound value change rate. The value obtained by dividing the total pitch difference between the changed sound and the default sound by the maximum variable range was defined as the pitch change rate. The calculated rate of change is shown in FIG. FIG. 7 shows phrase change rates (tone value change rate, pitch change rate) (%) for each position for default and variation. From the rate of change shown in FIG. 7, it was suggested that Var3 and Var2 are changing stepwise and Var1 is changing significantly with respect to the default phrase. The calculated rate of change was consistent with the results of the impression survey by observation and interview. Thus, the phrase change rate can be expressed numerically, and it can be seen that the numerical result matches the result of an actual impression survey or the like.

  <Combination of Sound Cell Blocks for Problem> Next, with reference to FIG. 5, a combination of sound cell blocks used for execution of the problem using the system of this embodiment will be described. FIG. 5 is a schematic diagram showing a combination of blocks used for the problem of the present embodiment and a state after rearrangement. In the block tray 98 shown in FIG. 5A, default sound cell blocks SB10 to SB40 are set in random order. A case where only the default sound cell blocks SB10, 20, 30, 40 are used and rearranged in the correct order on the work board 20 as shown in FIG. The serial task Ex0 is used to explain the task to the subject.

  Further, as shown in FIG. 5B, the default sound cell blocks SB10, 20, 30, 40 and the variation Var1 sound cell blocks SB11, 21, 31, 41 are set in the block tray 98 in random order. Therefore, the case of rearranging as shown in FIG. The variation Var1 used in the task Ex1 has the greatest variation in the song compared to the default song (the phrase change rate is high), so that the difference from the default is easy to understand and the task is relatively easy to achieve. Therefore, this matrix task Ex1 should be used for practice.

  As shown in FIG. 5 (C), the default sound cell blocks SB10, 20, 30, 40 and the sound cell blocks SB12, 22, 32, 42 of the variation Var2 having a medium phrase change rate are divided into the block tray 98. The case of rearranging from the state set in random order as shown in FIG. Similarly, as shown in FIG. 5D, a default sound cell block SB10, 20, 30, 40 and a sound cell block SB13, 23, 33, 43 of variation Var3 with a low phrase change rate are replaced with a block tray 98. The case of rearranging from the state set in random order as shown in FIG. 5 (F) is defined as a matrix task Ex3. The matrix tasks Ex2 and Ex3 are the tasks for actually acquiring the subject data 84. Although not used in this embodiment, as shown in FIG. 5E, the default sound cell blocks SB10 to SB10-40 prepared on the block tray 100 and all the sound cell blocks SB11 of the variations Var1 to Var3 are used. A case in which all of ˜41, 12 to 42, and 13 to 43 are used and rearranged from the state set in random order as shown in FIG. 5F may be set as the matrix task Ex4.

  <Procedure from start of task to determination of cognitive function> Next, with reference to FIG. 4 as well, from the execution of the task using the screening support system 10 of the present invention to the determination of the cognitive function using the result The procedure of will be described. In addition, the analysis database 90 used in the subsequent procedures is not related to the subject who performs the task of the present embodiment, and the subject of the present invention and a known cognitive function evaluation test are performed on a large number of subjects in advance. The data for evaluation calculated from the task log data and the correlation / test data calculated from the cognitive function evaluation test data are accumulated.

  First, in a state where the default sound cell blocks SB10 to SB40 are arranged in the correct order on the work board 20, the play selection buttons 42 to 48 on the work board 20 are all pushed, and then the play button 50 is pushed to complete the completed music. Confirmation (step S10 in FIG. 3). A sample of task execution using the sound cell blocks SB10 to SB40 is performed by, for example, an examiner (or an assistant of the subject). When the reproduction button 50 is pressed, the two-dimensional barcodes BA10-40 attached to the sound cell blocks SB10-40 placed on the work board 20 are read by the barcode readers 32-38, and a reproduction instruction is given together with the read information. Is sent to the log acquisition arithmetic device 60. In the log acquisition computing device 60, when the reproduction instruction and the read information are received, the phrase reproduction program 66 reads the phrase data corresponding to the read information with reference to the phrase database 82, and according to the arrangement order on the work board 20. The playback instruction is sent to the audio output unit 92 so that the playback is performed.

  Next, a sound cell block group is prepared by mixing the default and variation sound cell blocks (step S12). What is prepared is for the tasks Ex1 to Ex3 shown in FIGS. Then, if necessary, the subject is actually rearranged on the work board 20 using the sound cell block SB using the block group for the serial task Ex0 or the matrix task Ex1. To practice (step S14). When the subject confirms how to perform the task, the actual task is performed. Here, it is assumed that the matrix task Ex2 is performed, and the subject takes out an arbitrary sound cell block SB from the block tray 98 shown in FIG. Arrange in order (step S16). Then, the playback selection buttons 42 to 48 are pressed to select a phrase to be played back, and the playback button 50 is pressed to play back the phrase continuously to confirm the song (step S18). The reproduction procedure on the log acquisition arithmetic device 60 side is the same as step S10 described above.

  When the phrase is confirmed, the sound cell blocks SB are rearranged on the work board 20 and reproduced again to confirm the phrase (step S20). This rearrangement and reproduction are performed until the default sound cell blocks SB10 to SB40 are arranged in the correct order and the music is completed (achievement of task) (step S22). On the other hand, in the log acquisition arithmetic device 60, a log of the work process by the subject from the start of the task to the achievement (or the abandonment of the task) while outputting the audio of the phrase according to the reproduction instruction from the work board 20 The data is acquired by the log acquisition calculation program 68 (step S24), and stored as the task log data 86 of the subject data 84. It should be noted that the point at which playback after the sound cell blocks SB are arranged in the correct order is regarded as the achievement of the task. The start and end of the task may be determined by using the reset button 54 provided on the work board 20 or may be determined using the input unit 96 of the log acquisition arithmetic device 60. It should be noted that the subject or the examiner will determine whether to give up the task.

  The task log data 86 is acquired, for example, by the interval and the number of phrase playback instructions performed until the task is achieved or given up, and the sound cell on the work board 20 at the time when the playback instruction is issued. This is the position of the block SB. FIG. 8 shows the subject data 84 for the subject who has achieved the matrix task Ex2, and the task log data 86 in FIG. 8 includes “act”, “elapsed time”, “act time”, “number” 1 to 4 "are included. Here, “ACT” indicates the order (or the number of times) of a series of actions from when the subject presses the playback button 50 to when the subject presses the playback button 50 next time. “Elapsed time” indicates the elapsed time from the start of the task. The “act time” is the time required for each act, and here, the interval at which the play button 50 is pressed is regarded as the act time. The number of the sound cell corresponding to the sound cell block SB at each position is determined by referring to the phrase database 82 based on the identification information read by the barcode readers 32-38.

  When only the cell number (for example, “32”) is described in the position column of FIG. 10, the sound cell block SB is placed and the sound of the phrase corresponding to that block is heard. Also, in the position column of the figure, when “/” is written in front of the cell number (for example, “/ 20”), it means that the sound cell block SB is placed on the board but is not reproduced. Show. Also, the part marked with “↓” in the same position column shows the case where the sound cell block SB is not replaced and the sound is not reproduced as it is in the previous act. Further, in the column in the same position column, the portion where the same cell number continues indicates a state where the correct position is intentionally and finally fixed. Furthermore, in the position column, the numbers shown in white are the acts after placing the sound cell block in the correct position and listening to it, and block operations that have been placed in the wrong position or removed from the position. Show. If a position is left open for the task execution procedure, it means that the correct answer has not been confirmed.

  Next, the log acquisition calculation program 68 calculates evaluation data 88 for estimating the test result of the cognitive function evaluation of the screening target based on the acquired task log data 86 (step S26). Stored as person data 84. For example, the portion surrounded by the alternate long and short dash line in FIG. In the present embodiment, the evaluation data 88 is “total act time”, “act number”, “average act time”, and “step number”.

  The “total act time” is a work-up (when the log acquisition computing device 60 determines that the sound cell blocks SB are arranged in the correct order and the performance for confirming them has been completed, or the subject completes the task. Or, the total act time until it is announced that it is difficult to continue (abortion) or an answer is requested, or when it can be confirmed that the examiner declares whether or not to cancel. Therefore, in the case of the task achiever, “total act time” has the same meaning as “completion time”. The “act number” is the number of times a reproduction instruction has been given before workup. In the case of a person who has achieved the task, this is the number of acts that have been instructed to be played before the song is completed. The “average act time” is a time obtained by dividing the “total act time” by the “act number”, and in the case of a person who has achieved the task, has the same meaning as the time obtained by dividing the completion time by the act number.

  The “number of steps” is the number of times that the correct block is arranged in one or more of the set portions 22 to 28 of the work board 20 and the state is intentionally determined by the subject (progression stage of the task). . For example, in FIG. 8, the number of correct positions when the subject intentionally fixes the correct block is recorded. In Acts 1 to 4, the number of correct positions is 0. In Acts 5 and 6, since the block of the first position is correct, the number of correct positions is 1. Similarly, the number of correct positions for Acts 7 to 9 is 2, the number of correct positions for Acts 10 to 12 is 3, and the number of correct positions for Act 13 is 4. Accordingly, since the number of correct positions increases from 0 to 4 by one step, the “number of steps” is “5”. In the case of a matrix task that is completed in 4 cells, in many cases, the number of correct positions until completing a song is 0 to 4, and the number of correct positions increases by one after multiple acts. . However, since a plurality of blocks may be correctly positioned at the same time in one act, the number of steps is not necessarily five and may be “4”.

  Next, in the log acquisition arithmetic device 60, the determination program 70 estimates the cognitive function evaluation test result by referring to the analysis database 90 based on the evaluation data 88 (step S28), and determines the cognitive function. Is performed (step S30). The procedure for obtaining the evaluation data used for creating the analysis database 90 is performed in the same manner as steps S10 to S26 described above. By preparing the analysis database 90 in advance, the subject subject of the present embodiment can determine whether or not a tendency of dementia is observed to some extent from the result of the task. Therefore, if there is no need, you can skip the cognitive function evaluation test such as MMSE, and if there is a tendency of dementia, it is motivated to take the cognitive function evaluation test such as MMSE. can do.

  <Specific Examples of Correlation / Test Data, etc.> Here, specific examples of the correlation / test data included in the analysis database 90 used when the cognitive function is determined by the above-described procedure will be described. FIG. 9 shows the result of a significant difference test for the cognitive function evaluation between the achievement group and the non-achievement group of the matrix task Ex2 of this example. Note that “unachieved” of the task means that the matrix task could not be achieved without follow-up by the examiner, and “achievement” of the issue means that the matrix task could be achieved without following the examiner. Refers to cases. The MMSE is a comprehensive cognitive function test, 1) time orientation, 2) location orientation, 3) memorization, 4) attention and calculation, 5) recall, 6) designation, 7) Repetition, 8) Three-step command, 9) Reading comprehension, 10) Writing, 11) Consists of the lower 11 items. The test result of MMSE is indicated with a score of 30 points, and dementia is suspected at 23 points or less. TMT-A is a test that mainly checks “continuation and selection of attention, visual search, visual motor coordination, etc.”. TMT-B is a test that mainly checks “attention and concept conversion ability, performance ability, etc.”. The Kana-Hiroi test is a test that mainly checks “frontal function, attention distribution ability, etc.”. If the number of correct answers in the Kana-Hiroi test is less than the age-specific boundary value, dementia is suspected. From FIG. 9, for example, the MMSE score of a subject who has not achieved the matrix task is estimated to be in the range of 24.6 ± 2.9 points, and may be 23 points or less where dementia is suspected However, the MMSE score of subjects who achieved the matrix task is estimated to be in the range of 28.2 ± 2.3, indicating that there is little suspicion of dementia. In addition, the result of the Kana-hiroi test for subjects who have not achieved the matrix task is estimated to be in the range of -2.1 ± 2.8, and may be below the age-specific boundary value for which dementia is suspected However, the results of the Kana Hiroshi test of subjects who achieved the matrix task are estimated to be in the range of 12.0 ± 5.0 points, indicating that there is little suspicion of dementia. Dementia is rarely determined only by the TMT result, but the approximate values of the achieved group and the unachieved group are estimated from FIG. 9 and combined with other cognitive function evaluation tests. It can be used as a reference when determining dementia.

  FIG. 10 shows a calculation result (correlation data 90A) on the correlation between the cognitive function evaluation of the subject who achieved the matrix task Ex2 of this embodiment and the task data. The cognitive function evaluation test is the MMSE, TMT-A, TMT-B, and the Kana Hiroi test, and the evaluation data is the above-mentioned “completion time”, “number of steps”, “average act time”, “act number” It was. The numerical value in the figure shows the correlation coefficient (γ) indicating how high the correlation is.

  The correlation coefficient (γ) shown in FIG. 10 is a value from 0 to ± 1, and the larger the absolute value, the higher the correlation. For example, for the two parameters A and B for which correlation is examined, the relationship that B increases as A increases is + (plus), and in the opposite case that B decreases as A increases-(minus) ) When the absolute value of the correlation coefficient is in the range of 0.4 to 0.7, there is a considerable correlation, and when it is in the range of 0.7 to 1, it is determined that there is a strong correlation. In FIG. 10, the statistically significant correlations are TMT-A and completion time, all cognitive function evaluations and number of steps, MMSE and average act time, and cognitive function evaluations and acts other than TMT-B. Is a number.

  Of these, the correlation between MMSE and evaluation data will be examined one by one. The higher the score of MMSE, the lower the probability of dementia. Looking at the relationship between MMSE and completion time, γ is -0.200, and it seems that there is a negative correlation (the higher the MMSE score, the shorter the completion time), but it is statistically clearly related It does not lead to.

  Next, there is a statistically negative correlation between the MMSE and the number of steps (the higher the MMSE score, the smaller the number of steps). The reason is thought to be that people with higher cognitive functions remember the contents of multiple blocks at a time and proceed with the tasks well. Next, there is a statistically positive relationship between the MMSE and the average act time (the higher the score of the MMSE, the longer the average act time). This seems to be the opposite, but it is easy to understand when considering the relationship with the next number of acts. In other words, there is a statistically negative correlation between the MMSE and the number of acts (the higher the MMSE score, the smaller the number of acts). This is because people with low cognitive functions tend to concentrate their attention on the correctness of one position because their ability to memorize a lot of things at once and the ability to think about the arrangement from a bird's-eye view are declining. As a result, listening back one block at a time, the number of acts increases instead of shortening the average act time. Conversely, people with high cognitive functions have high memory and performance, so they listen to multiple blocks at once and perform multiple sorts at once. As a result, the average act time described above becomes longer and the number of acts decreases.

  Though the discussion on TMT-A, TMT-B, Kana Hiroi test and individual correlations of evaluation data is omitted, anyway, there is some correlation for those with high absolute value of correlation coefficient The result can be used. That is, in this embodiment, the diagnosis of dementia is not performed directly from the task log data 86 of the matrix task using the sound cell block SB, but the correlation between the evaluation data 88 and the result of the cognitive function evaluation test (for example, People with short average act times tend to have low MMSE scores).

  FIG. 11 shows correlation data 90B between two items (attention and calculation, recall) of the lower 11 items constituting the MMSE and evaluation data (completion time, number of steps, average act time, and number of acts). ing. The numerical value in the figure is the correlation coefficient (γ). The correlation data 90B of FIG. 11 is created based on a cognitive function evaluation test conducted in advance for a large number of subjects who achieved the matrix task Ex2 shown in FIG. “Caution and calculation” is an item for checking working memory, and “recollection” is an item for checking recent memory. As shown in FIG. 11, it was confirmed that “attention and calculation” and “recall” are highly correlated with the number of steps, the average act time, and the number of acts. In mild cognitive impairment, the first stage of dementia, recent memory is likely to be impaired first, and in early stages of Alzheimer-type dementia, which represents more than 60% of dementia, Since the “calculation” is reduced, these evaluation data can be used for screening for mild cognitive impairment and early Alzheimer-type dementia.

  Early detection is the most important measure against dementia, but nobody wants to have a cognitive function test because they don't want to be diagnosed with dementia. In addition, some subjects may cause anxiety, tension, defense reaction, etc., and correct results may not be obtained. On the other hand, in the system of the present invention, since only the work of assembling a nostalgic song known to the subject is performed using the sound cell block SB, most (85% or more) of the subjects said “It was fun. “I want to try again”. Thus, by referring to the analysis database 90 prepared in advance from the evaluation data 88 obtained based on the log data of the problem using the sound cell block, the approximate score of the cognitive function evaluation test (MMSE etc.) can be obtained. Can be estimated. In addition, if you ask them to perform tasks periodically and observe the evaluation data 88 over time, it will also be a motivation to judge whether or not it is better to take a cognitive function test and to receive a cognitive function test. .

  As described above, according to the first embodiment, the work sound cell block SB to which the two-dimensional barcode BA corresponding to each divided phrase when one musical piece is divided into four phrases is attached to the barcode reader 32 to 38 are rearranged on the work board 20 provided in the set portions 22 to 28 of the first to fourth positions. Connected to the work board 20 is a log acquisition calculation device 60 in which phrase data of music corresponding to the identification information read by the bar code readers 32 to 38 is stored. When the subject gives an instruction to reproduce a phrase during the process of rearranging the sound cell blocks SB, the log acquisition arithmetic device 60 reads out the corresponding phrase from the phrase database 82 and outputs it from the audio output unit 92. In addition, the subject who has confirmed the reproduced phrase obtains a log of work performed until the sound cell block SB is in the same order as the music before division, and the test result of the cognitive function evaluation is obtained based on the log data. Evaluation data 88 for estimation was calculated. For this reason, the following effects are acquired.

(1) An analysis database 90 showing the correlation and significant difference between the evaluation data 88 and the test result of the cognitive function evaluation is prepared in advance, and the cognitive function is obtained from the evaluation data 88 of the subject of the subject of this embodiment. Since the test result is estimated and the cognitive function is determined, it can be used as a motivation for taking the cognitive function evaluation test. In addition, since the analysis database 90 is prepared in advance, the cognitive function can be determined to some extent only by performing the task of this embodiment.
(2) Since the evaluation data 88 is obtained by rearranging the sound blocks SB, the subject can enjoy working. For this reason, there is no resistance to regularly performing tasks, the transition of results over time can be observed, and the degree of progression and improvement of dementia can be grasped.
(3) By using a sound cell block corresponding to the split phrase of the default song that does not add variations to the original song, and a sound cell block corresponding to the divided phrase of the variation song that added variations to the original song, The difficulty of the task is higher than when only the default songs are rearranged (serial task). In addition, by preparing a plurality of arrangements with different phrase change rates as variation songs, the difficulty level of the matrix task can be adjusted.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. In addition, the same code | symbol shall be used for the component which is the same as that of Example 1 mentioned above, or respond | corresponds. In the first embodiment described above, the sound cell blocks SB for the subject to actually hold and work with the hand are used, and the sound cell blocks SB are rearranged on the work board 20. On the other hand, the second embodiment is an example in which the task of rearranging the sound cell blocks SB is performed using a virtual block and a virtual board displayed on the screen of a terminal such as a tablet PC. As shown in FIG. 12, the screening support system 200 of this embodiment is configured by only a tablet PC 210, for example. The tablet PC 210 includes a display unit 212 such as a display, an input unit such as a keyboard 214 and a mouse 216, and an output unit such as a speaker 218. Further, the tablet PC 210 includes a log acquisition calculation unit 230.

  The log acquisition calculation unit 230 basically has the same system configuration as the log acquisition calculation device 60 of the first embodiment, and includes a CPU 62, a program memory 64, and a data memory 80. However, in this embodiment, the program memory 64 is provided with a work screen display program 76 in addition to the programs of the first embodiment. The work screen display program 76 is for displaying the sound cell block SB and the block tray 98 of the first embodiment and the work board 20 as virtual blocks and virtual boards displayed on the display unit 212. It is. The sound cell block SB in the block tray 98 in the display unit 212 of FIG. 12 is dragged and dropped by the arrow 222 on the screen by operating the mouse 216 or the like, thereby allowing any sound on the work board 20. It can be moved to the position. Of course, when the display unit 212 is a touch panel type, the sound cell block SB may be moved by touching with a finger.

  In this embodiment, the reproduction selection buttons 42 to 48 on the work board 20 which is a virtual board can select a position to be reproduced by checking a blank button. The play button 50, the stop button 52, and the reset button 54 can be operated by selecting and determining with an arrow 222 displayed on the screen. In the present embodiment, the phrase reproduction program 66 and the log acquisition calculation program 68 are linked with the work screen display program 76, and the arrangement of the sound cell blocks SB displayed on the work screen 220 and the reproduction selection buttons 42 to 48. Phrase playback and task log acquisition are performed according to the selection status. The specific phrase reproduction procedure, log acquisition procedure, correlation data calculation using log data, and cognitive function determination are the same as in the first embodiment.

  Thus, according to the present embodiment, the sound cell block SB and the work board 20 of the first embodiment are displayed on the tablet PC 210 as virtual blocks and virtual boards, and the sound cell blocks SB are arranged in the display screen. The log acquisition calculation unit 230 is provided to perform the replacement and perform log acquisition and calculation based on the result. For this reason, in addition to the effects of the first embodiment described above, it is possible to easily perform the screening of the cognitive function evaluation using only the tablet PC 210, which is convenient for carrying. Further, it can be used not only for screening purposes but also as a block rearrangement play.

In addition, this invention is not limited to the Example mentioned above, A various change can be added in the range which does not deviate from the summary of this invention. For example, the following are also included.
(1) The number of music divisions described in the first embodiment is an example, and the number of divisions may be increased or decreased as necessary. Moreover, the kind of variation music is also an example, and may be increased or decreased as necessary.
(2) In the first embodiment, the composition of the song is performed by mixing the default song and the divided phrase of one type of variation song, but this is also an example, and it may be a serial task only for rearranging the default song. It is also possible to assemble music by mixing two or more types of variation phrases.

(3) The configuration of the sound cell block SB and the work board 20 shown in the first embodiment is an example, and the design can be changed as appropriate as long as the arrangement of the divided phrases (sound cells) can be understood. For example, in the first embodiment, the two-dimensional bar code BA provided in the sound cell block SB is read by the bar code readers 32 through 38 provided in the set units 22 through 28 of the work board 20. However, this is also an example. For example, a resistance is provided on the bottom surface of the sound cell block SB, and contacts are provided on the bottom surfaces of the set portions 22 to 28 of the work board 20 to read the resistance value. A corresponding divided phrase may be specified.
(4) In the above embodiment, the sound cell block SB is used as the work block used by the subject. However, the term “sound cell block” is merely an example, and the block, cell, peg, piece, etc. You may call it.

(5) By loading a computer-readable screening support program into a computer, a device similar to the log acquisition arithmetic device 60 of the first embodiment described above may be configured. Similarly, the screening support system according to the second embodiment may be configured by reading a computer-readable screening support program into a terminal such as a tablet PC.
(6) In the embodiment, based on the evaluation data 88 obtained from the task log data 86, referring to the analysis database 90, estimating the result of the cognitive function evaluation test, and determining the cognitive function, etc. However, dementia or the like may be determined from only the evaluation data 88 by increasing the difficulty level of the task or combining the results of a plurality of tasks.
(7) In the first embodiment, “hometown” is used as the subject song, but this is also an example, and various other known songs may be used. Moreover, it is not limited to a song.

(8) In the first embodiment, the phrase change rate of the variation song with respect to the default song is quantified, but this phrase change rate may be used for screening such as immediate memory and music phrase discrimination. . When used as a music system for development support, the phrase change rate can be used as an indicator of the degree of reach of the subject.
(9) In Example 1, the present invention was used for screening of cognitive function of dementia, but this is also an example. For example, the present invention is used for screening of other cognitive functions such as developmental disorders. Also good. Further, it is not always necessary to use for some kind of screening, and the rearrangement of the sound cell blocks SB may be performed simply as a music game, and does not preclude performing for rehabilitation or development support.
(10) In the second embodiment, the tablet PC 210 has been described as an example. However, a notebook PC may be used, and a similar configuration may be realized with a desktop PC. Or you may use portable communication terminals, such as a smart phone.

  According to the present invention, each set unit is provided with a reading means for reading the work block with the identification information corresponding to each divided phrase when one musical piece is divided into a plurality of phrases. Sort on a working board. The work board is connected to a log acquisition arithmetic unit in which the phrase data of the music corresponding to the identification information read by the reading means is recorded. The phrase to be played is read and played. The subject who confirmed the reproduced phrase obtains a log of the work in which the block is rearranged until the block is in the same order as the music before division by the log acquisition arithmetic device, and the cognitive function evaluation is performed based on the log data The evaluation data for estimating the test result is calculated. And, in advance, prepared an analysis database showing the correlation or significant difference between the evaluation data and cognitive function evaluation test data, so that the test result of the cognitive function evaluation was estimated from the evaluation data, It can be applied to applications such as screening in the previous stage of cognitive function tests.
