Description

CROSS-REFERENCE TO RELATED APPLICATION
• The present application claims the benefit of U.S. Provisional Application 60/586,158, filed Jul. 8, 2004, the entirety of which is incorporated herein by reference.
FIELD OF INVENTION
• The present invention relates generally to the field of diagnosing a medical condition of a person, and specifically to the field of diagnosing a medical condition of a person based on the person's answers to a set of questions. The invention is particularly suited for the diagnosis of headache based conditions but is not so limited.
BACKGROUND OF INVENTION
• Various methods and systems exist for diagnosing medical conditions. However, many of these diagnostic systems and methods require that the subject person meet with a doctor or other health care professional to either carry out the diagnostic method or interpret the data obtained from the diagnostic system or method. Such diagnostic systems and methods are unsatisfactory because many people dislike meeting and/or consulting with doctors or other health care professionals for diagnosis. This results in many people receiving inadequate or no treatment, thereby resulting in a worsening of the medical condition and/or additional harm to the person. For obvious reasons, this is undesirable.
• Additionally, many existing diagnostic methods and systems are either very complicated to use or are expensive. Thus, these diagnostic systems and methods result in a large percentage of the population going untreated. Still, other diagnostic systems and methods are unreliable.
• While diagnostic systems and methods that are purely computer based have become more popular, computer based diagnostic systems require that the user both have a computer and be aware of the diagnostic software. A further drawback of such computer based systems is that they tend to be expensive and require a working knowledge of the software and its functionality.
• One particular area that has seen an increase in either misdiagnosis or failure of patients to seek diagnosis is that of headaches. Migraine, tension-type headaches, and other types of headache-based medical conditions often go undiagnosed because most primary care physicians do not have the expertise in diagnosing these conditions. Additionally, many people do not want to seek professional attention for a medical condition for which they are uncertain of having.
SUMMARY OF THE INVENTION
• It is therefore an object of the present invention to provide a new diagnostic system and method.
• Another object of the present invention is to provide a diagnostic system and method that can be used by people for self-diagnosis in the comfort of their own homes.
• Yet another object of the present invention is to provide a diagnostic system and method that gives a user an indication that there is an increased likelihood of having a medical condition.
• Still another object of the present invention is to provide a diagnostic system and method that motivates people to seek additional profession help for a medical condition.
• A further object of the present invention is to provide a diagnostic system and method that is easy to use, understand, and/or distribute.
• A yet further object of the present invention is to provide a diagnostic system and method that is cost-effective to manufacture.
• A still further object of the present invention is to provide a system and method for diagnosing headache related medical conditions.
• These and other object are met by the present invention which, in one embodiment, is a diagnostic system comprising: a form comprising one or more diagnostic questions and one or more possible answers to each question; a first overlay comprising one or more windows and one or more diagnostic fields, wherein when the first overlay is positioned over the form, answers indicative of the user having a first medical condition are visible through the windows of the first overlay; and wherein the one or more diagnostic fields contain criteria for diagnosing the user with the first medical condition based on the user's selection of answers that are visible through the windows of the first overlay.
• In another embodiment, the invention is a diagnostic method comprising: a) answering one or more diagnostic questions pertaining to a user's health by selecting one or more answers, the one or more diagnostic questions and answers being provided on a form; b) positioning a first overlay having one or more windows and one or more diagnostic fields atop the form so that the answers indicative of the user having a first medical condition are visible through the windows of the first overlay; and c) using criteria in the diagnostic fields of the first overlay, diagnosing the user with the first medical condition based on the user's selection of answers that are visible through the windows of the first overlay.
• In still another embodiment, the invention is a computer-based diagnostic system comprising: means for displaying an electronic form having one or more diagnostic questions and corresponding answers to the diagnostic question, each set of answers containing at least one answer that is indicative of the user having a first medical condition; means for a user to select one or more of the answers; means for identifying the answers selected by the user that are indicative of the user having the first medical condition; and means for diagnosing the user with the first medical condition based on the user's selection of answers that are indicative of the user having the first medical condition.

DETAILED DESCRIPTION OF THE DRAWINGS
• FIG. 1 illustrates a headachediagnostic system100 according to an embodiment of the present invention. The headachediagnostic system100 comprises adiagnostic file2 and a questionnaire sheet/form3. While the illustrated embodiment of thediagnostic system100 is specifically designed for the diagnosis of headaches, such as migraines and tension-type headaches, the invention is not so limited. Those skilled in the art will understand that the invention can be adapted for diagnosis of almost any type of medical condition (mental or physical), health status, or physiological impairment. As used herein, the term diagnosis, and all derivative thereof, is intended to encompass definitive diagnosis of medical conditions along with determinations of increased or decreased likelihood of having or not having a medical condition so that the user can seek a definitive diagnosis from a healthcare professional.
• Thediagnostic file2 comprises afirst overlay20 and asecond overlay21. The first andsecond overlays20,21 are formed from a single piece of material that is folded in half atcrease22. Once creased, the first andsecond overlays20,21 are connected to one another along thebottom edge23. As a result, the first andsecond overlays20,21 are connected along two sides, thereby forming apocket24 capable of slidably receivingquestionnaire form3 from either of the two open sides. The connection alongbottom edge23 can be accomplished by a low heat weld or the proper use of sutures, staples, adhesive, tape, a tongue and groove assembly, stamping, or the like. Athumbnail cutout25 is provided along the side of thefirst overlay20 along the open lateral side of thediagnostic file2 so as to afford easy separation of the first andsecond overlays20,21 during the insertion of thequestionnaire form3. Thiscutout25 can take on any desired shape or size.
• In other embodiments of the invention, the first andsecond overlays20,21 of thediagnostic file2 can be separate pieces of material that are connected along one or more edges using one of the above identified connection techniques to form thediagnostic file2. Theoverlays20,21 can be formed of one or more layers of thin flexible materials, such as plastic, paper, synthetic polymers, or the like. Thediagnostic file2 is preferably sized so thatpocket24 fully receives a standard sized piece of paper, such as A-4 or 8.5×11.5 paper sizes. However, the invention is not limited to any specific material of construction or dimensions. In some embodiments of the invention, only asingle overlay20 or21 may be used in combination with thequestionnaire form3 to diagnose a medical condition. In such embodiments, theoverlay20 or21 will be simply positioned over and aligned with thequestionnaire form3 during use.
• Thequestionnaire form3 is a sheet of paper comprising screening questions on one side and diagnostic questions on the opposite side. The screening questions and the diagnostic questions are carefully selected to diagnose a targeted medical condition (in this case migraines and tension-type headaches) and printed on thequestionnaire form3 prior to distribution in a predetermined pattern. This will be discussed in greater detail below. Thequestionnaire form3 can be made of a variety of materials which can be written on or otherwise marked, including without limitation, paper, plastic, cardboard, metal, etc. If desired, thequestionnaire form3 can be constructed to be either disposable or reusable. For example, in a reusable embodiment, thequestionnaire form3 may be formed of plastic (or comprise a plastic or polymer coating) from which pencil, ink, or marker indicia can be easily erased. In disposable embodiments, a simple piece of paper may be used for ease of reproduction and to reduce manufacturing costs.
• Referring now toFIGS. 2A and 2B, thequestionnaire form3 is illustrated according to an embodiment of the present invention. Thequestionnaire form3 is a sheet of paper comprising screening questions4-5 on one side (FIG. 2A) and diagnostic questions6-13 on the opposite side (FIG. 2B). Thequestionnaire form3 is designed with the intention that the user answer the screening questions4-5 on the first side before proceeding to the second side of the questionnaire form to answer the diagnostic questions6-13.
• Referring solely toFIG. 2A, thefirst side14 of thequestionnaire form3 comprises two screening questions4-5. While two screening questions4-5 are used in the example, any number of screening questions may be used. The exact number of screening questions will be dictated on a case-by-case basis, considering such factors as the type of medical condition being diagnosed, target patient group, etc. In some embodiments of thequestionnaire form3, the screening questions may be omitted. In such embodiments, thefirst side14 of thequestionnaire form3 may be identical to the second side15 (FIG. 2B), contain different diagnostic questions, or contain general user instructions and/or advertisements.
• A choice of correspondinganswers4A-4B and5A-5B are provided on thefirst side14 of thequestionnaire form3 that respectively correspond to thescreening questions4,5. Thefirst side14 further comprisesinstructions16 for determining whether, based on the user's answers to the screening questions4-5, the user needs to proceed with answering the next screening question and/or the diagnostic questions6-13 on thesecond side15 of thequestionnaire form3.
• In the illustrated embodiment of thequestionnaire form3, which is designed for migraine and/or tension-type headache diagnosis, the screening questions4-5 respectively pertain to whether the user experienced a headache in the last several years and whether the onset of such headaches affected the user's ability to carry out their daily routine. Regardingscreening question4 specifically, each possible answers4A,4B has correspondinginstructions16 which, depending on theanswer4A,4B selected, will direct the user to either proceed to thenext screening question5 or cease further completion of thequestionnaire form3. Regardingscreening question5 specifically, each possible answers5A,5B has correspondinginstructions16 which will direct the user to either proceed to answer the diagnostic questions6-13 on thesecond side15 of thequestionnaire form3 or cease further completion of thequestionnaire form3.
• The screening questions4,5 are designed so that if the user selects an answer (which in this case areanswers4B or5B) that correspond toinstructions16 that instruct the user to cease further completion of thequestionnaire form3, the diagnosis is that the user does not have (or at least is not likely to have) the medical condition(s) being screened for, which in this case is migraine and tension-type headaches. However, if the user selects answers (which in this case are bothanswers4A or5A) that correspond toinstructions16 that instruct the user to continue with completion of thesecond side15 of thequestionnaire form3, the user has not been screened out, and is likely in need of further diagnosis/inquiry, which in this case is additional diagnosis for migraine and tension-type headaches.
• Referring now toFIG. 2B, thesecond side15 of thequestionnaire form3 is illustrated. Eight diagnostic questions6-13 are provided on thesecond side15 of thequestionnaire form3. The diagnostic questions6-13 are carefully drafted and selected so that the user's answers are indicative of the user having or not having a certain medical condition within a reasonable degree of medical certainty, which in this case is migraines and/or tension-type headaches. Specifically,diagnostic question6 pertains to the frequency of which a user experiences headaches.Diagnostic question7 pertains to how long the user's headaches last if no medication is taken.Diagnostic question8 pertains to whether the user experiences the onset of aura symptoms during headaches, such scintillating scotomata and/or visual defect.Diagnostic question9 pertains to the location of the headache pain.Diagnostic question10 pertains to the type of headache pain.Diagnostic question11 pertains to the severity of the user's headache pain.Diagnostic question12 pertains to whether the user's performance of certain physical activities affects/worsens the headache pain.Diagnostic question13 pertains to whether the user experiences the onset of additional headache-related symptoms.
• While a total of eight diagnostic questions6-13 are used in the illustrated questionnaire form, the invention is not so limited. Any combination of the diagnostic questions6-13 can be used and/or other diagnostic questions can be added if desired. However, it is preferable that testing and/or research be performed to determine the proper number, identity, and combination of diagnostic questions that will reliably diagnose the target medical condition(s) within a certain degree of accuracy. It has been determined that the diagnostic questions6-13 are reliable in diagnosing migraine and/or tension-type headaches.
• Each diagnostic question6-13 has one or morepossible answers6A-13D that correspond to the appropriate diagnostic question6-13. (Questions and answers having like numerical prefixes correspond to one another.) The answer choices for each diagnostic question6-13 have one or more answers that are indicative of a person having a targeted medical condition, which in this case is migraines and/or tension-type headaches. For example, answers6A and6B correspond todiagnostic question6. As will be explained in detail below with respect toFIG. 5,answer6A is indicative of the user having migraines, while answer is6B is not. Some diagnostic questions6-13 can have multiple answers that are indicative of the user having a targeted medical condition. In some cases, one answer can be indicative of more than one medical condition being targeted. The positioning and arrangement of theanswers6A-13D on thequestionnaire form3 are chosen so that answers indicative of the user having the medical condition being diagnosed are in a corresponding spatial relationship to thewindows26 of thediagnostic file2.
• Referring now toFIGS. 3A and 3B, thefirst overlay20 andsecond overlay21 of thediagnostic file2 are illustrated in detail. The construction of thediagnostic file2 has already been discussed above in relation toFIG. 1.
• FIG. 3A. is a front view of thefirst overlay20, which is specifically designed for use in combination with thesecond side15 of thequestionnaire form3 to diagnose migraines. Thefirst overlay20 of thediagnostic file2 comprises a plurality oftransparent windows26 spatially arranged at predetermined locations and designed to be a predetermined size. Eachwindow26 is designed so that only those answers on thequestionnaire form3 that are indicative of the user having migraines will be visible therethrough when thequestionnaire form3 is fully inserted into thepocket24 with thesecond side15 of thequestionnaire form3 facing thefirst overlay20. While thewindows26 are transparent sections of thefirst overlay20, thewindows26 can be formed in a variety of ways, including cutouts, etc. In some embodiments, theentire overlay20 may be constructed of a transparent material and thewindows26 may be formed by boxes or other indicia marked on the overlay.
• Thefirst overlay20 further comprises a plurality ofdiagnostic fields27. Thediagnostic fields27 contain criteria/instructions for diagnosing the user for migraines based on the user's selection ofanswers6A-13D on thequestionnaire form3 that are visible through thewindows26. While thediagnostic fields27 are illustrated as being in a separated/boxed-off areas of thefirst overlay20, the invention is not so limited. In some embodiments, thediagnostic fields27 may be mere areas on thefirst overlay20 containing text without any special delineation or demarcation. Only those answers on thequestionnaire form3 that are indicative of the user having migraines are visible through thewindows26 of thefirst overlay20 when thequestionnaire form3 is fully inserted into the diagnostic file2 (as shown inFIG. 5). Thediagnostic fields27 provide the user and/or health professional with the means to be able to perform a quick and reliable interpretation of the user's answers with respect to migraine diagnosis.
• FIG. 3B. is a front view of thesecond overlay21, which is specifically designed for use in combination with thesecond side15 of thequestionnaire form3 to diagnose tension-type headaches. Similar to that of thefirst overlay20, the second overlay comprises a plurality ofwindows26 anddiagnostic fields27. However, the positioning and size of eachwindow26 of thesecond overlay21 is designed so that only those answers onquestionnaire form3 that are indicative of the user having tension-type headaches will be visible therethrough when thequestionnaire form3 is fully inserted into thepocket24 with thesecond side15 of thequestionnaire form3 facing the second overlay21 (as shown inFIG. 7). Additionally, thediagnostic fields27 of thesecond overlay21 contain criteria/instructions for diagnosing the user for tension-type headaches based on the user's selection ofanswers6A-13D on thequestionnaire form3 that are visible through thewindows26 of thesecond overlay21. Only those answers on thequestionnaire form3 that are indicative of the user having tension-type headaches are visible through thewindows26 of thesecond overlay21 when thequestionnaire form3 is fully inserted into thediagnostic file2 with thesecond side15 of thequestionnaire form3 facing the second overlay21 (as shown inFIG. 7). Thediagnostic fields27 provide the user and/or health professional with the means to be able to perform a quick and reliable interpretation of the user's answers with respect to tension-type headache diagnosis.
• Referring now toFIGS. 4 and 5, the method by which a user is diagnosed with migraines using the headachediagnostic system100 according to an embodiment of the invention will be discussed. Starting withFIG. 4, the headachediagnostic system100, which includes thediagnostic file2 and thequestionnaire form3 is supplied to a user. In some cases, only thequestionnaire form3 will be supplied and a healthcare professional will have thediagnostic file2. Upon receiving thequestionnaire form3, the user first answers the screening question4-5 on thefirst side14 of the questionnaire form3 (as discussed above with respect to2A). Assuming that the user answers the screening questions4-5 so that he/she is instructed to continue with answering the diagnostic questions6-13 on thequestionnaire form3, the user then turns to thesecond side15 of thequestionnaire form3. The user then reads the diagnostic questions6-13 and selects theanswers6A-13D that are indicative of the user's health and physical conditions. In the illustration, a hypothetical user has selected his/her answers by marking an “X” on all answer that apply to his/her health status.
• Once the user has completed selecting his/heranswers6A-13D to the diagnostic questions6-13, the user slides/inserts thequestionnaire form3 into thepocket24 of thediagnostic file2 between the first andsecond overlays20,21, as indicated by the arrow. Thesecond side15 of thequestionnaire form3 faces thefirst overlay20 at this time. The user continues to insert/slide thequestionnaire form3 into thediagnostic file2 until thequestionnaire form3 is fully positioned therein (i.e., in a diagnostic position), as shown inFIG. 5.
• Referring now toFIG. 5, the components of the headachediagnostic system100 are arranged for migraine diagnosis, i.e., thequestionnaire form3 is fully and properly inserted into thepocket24 of thediagnostic file2 with thefirst side14 facing thefirst overlay20. As can be seen, only thoseanswers6A,7C,8A,9A,10A,11A,11B,12A,12B, and13A-13D to the diagnostic questions6-13 that are indicative of the user having migraines are aligned with and visible through thewindows26 of thefirst overlay20. The remaining answers to the diagnostic questions6-13 are not aligned with thewindows26 and are not visible therethough. Based on the user's selection ofanswers6A,8A,9A,10A,11B,12B and13A-D to the diagnostic questions6-13 that are visible through thewindows26 of the first overlay, and according to the criteria set forth in thediagnostic fields27 of thefirst overlay20, the user can be easily and reliably diagnosed with (or without) migraines. In the hypothetical example, the diagnosis is that there is a very high probability that the user has migraines based on his/her selection ofanswers6A,8A,9A,10A,11B,12B and13A-D.
• Referring toFIGS. 6 and 7, the headachediagnostic system100 can also be used to diagnose a user with tension-type headaches in a manner very similar to that described above with respect to migraine diagnosis. The only difference is that after the user has completed answering the diagnostic questions6-13, thequestionnaire form3 is inserted into thediagnostic file2 with thesecond side15 of thequestionnaire form3 facing thesecond overlay21, as shown inFIG. 6.
• FIG. 7 illustrates the components of the headachediagnostic system100 arranged for tension-type headache diagnosis, i.e., thequestionnaire form3 is fully and properly inserted into thepocket24 of thediagnostic file2 with thesecond side15 facing thesecond overlay21. When so positioned, only thoseanswers7B-7E,9B,10B-10D,11C,12C, and13A-13D to the diagnostic questions6-13 which are indicative of the user having tension-type headaches are aligned with and visible through thewindows26 of thesecond overlay21. The remaining answers to the diagnostic questions6-13 are not aligned with thewindows26 and are not visible therethrough. Based on the user's selection ofanswers7B,10B, and13A-13D to the diagnostic questions6-13 that are visible through thewindows26 of thesecond overlay21, and according to the criteria set forth in thediagnostic fields27 of thesecond overlay21, the user can be easily and reliably diagnosed with (or without) tension-type headaches. In the hypothetical example, the diagnosis is that there is a low probability that the user has tension-type headaches based on his/her selection ofanswers6A-13D.
• It is important to note that the relative spatial arrangement of theanswers6A-13D on thequestionnaire form3 and thewindows26 on the first andsecond overlays20,21 is critical to proper diagnosis. Moreover, it is important that thequestionnaire form3 be fully and properly inserted into thediagnostic file2 so as to avoid an inaccurate diagnosis.
• The headachediagnostic system100 can be used by for self diagnosis by a user or can be used by a healthcare professional to assist in diagnosis of migraines and tension-type headaches. For example, the headache diagnostic system100 (or just the questionnaire form3) can be handed out to patients in the waiting room of a hospital or other healthcare facility for completion by the user. Using thediagnostic file2, the doctor or other healthcare professional can then perform the migraine diagnosis based on the answers selected by the user on thequestionnaire form3. In other circumstances, the user can utilize the headachediagnostic system100 to perform a self diagnosis in the convenience of his/her home or at any other location. Depending on the resulting self-diagnosis, the user can then set up an appointment with a healthcare professional for further consultation.
• In some embodiments of the invention, thequestionnaire form3 can have the diagnostic questions6-13 on bothsides14,15. As a result, when thequestionnaire form3 is inserted into thediagnostic file2, the user and/or healthcare professional can perform the migraine and tension-type diagnosis without having to flip the orientation of thequestionnaire form3 in thediagnostic file2. In other embodiments of the invention, a folder-like diagnostic file does no have to be used. Instead a single overlay can be used wherein the questionnaire form is simply positioned underneath the overlay in a proper alignment.
• Turning now toFIG. 8, a schematic of a computer based migraine/tension-type headachediagnostic system200 is illustrated according to a second embodiment of the present invention. The computer-baseddiagnostic system200 comprises adisplay module260, auser input device210, asignal input port230, a suitably programmedmicroprocessor250, and acomputer memory medium240. TheCPU250, thememory medium240, and theinput port230 are located in acomputer housing220.
• TheCPU250 is a suitable microprocessor based programmable logic controller, personal computer, or the like. TheCPU250 is electrically and operably coupled to all components of thesystem200 that need to be controlled and/or communicated with. Thedisplay module260 can be a computer monitor or the like. Theinput device210 can be a keyboard, a mouse, a joystick, an interactive screen, or the like.
• Thememory medium240 comprises sufficient memory to store all of the necessary computer code, algorithms, and data necessary for the functioning of thesystem200. TheCPU250 is programmed with the proper algorithms to display an electronic version of the questionnaire form described above on thedisplay module260, the ability to facilitate the user to select answers on the electronic questionnaire form using theinput device210, the ability to identify the answers selected on the electronic questionnaire form that at are indicative of the user having the targeted medical condition, the ability to analyze the answers selected by the user on the electronic questionnaire form, and the ability to output a diagnosis based on the users selected answers and the analysis. As with thesystem100, the computer basedsystem200 can be used to diagnose any medical condition(s). The diagnosis output can be simple graphical representation of a YES or NO on the display module, or can be a more-detailed diagnosis, including additional instruction on follow-up procedure and the need for definitive diagnosis
• If desired, theCPU250 and thememory medium240 can be programmed to have an electronic version of the diagnostic file and/or single overlays, and perform a virtual insertion of the diagnostic form into the diagnostic file, similar to that described above. TheCPU250 can then perform the analysis based on the location of the answers selected by the user in view of their relationship with the virtual windows. Additionally, the interface on which the electronic questionnaire form is displayed may further comprise a button that can be selected by the user to indicate that the user has completed his/her answering of the form.
• The foregoing discussion discloses and describes merely exemplary embodiments of the present invention. As will be understood by those skilled in this art, the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
