Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application claims the benefit of United State
Provisional Application 60/586,158, filed Jul. 8, 2004, the
entirety of which is incorporated herein by reference.
FIELD OF INVENTION
[0002] 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
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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
[0007] It is therefore an object of the present invention to
provide a new diagnostic system and method.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] A further object of the present invention is to provide a
diagnostic system and method that is easy to use, understand,
and/or distribute.
[0012] A yet further object of the present invention is to provide
a diagnostic system and method that is cost-effective to
manufacture.
[0013] A still further object of the present invention is to
provide a system and method for diagnosing headache related medical
conditions.
[0014] 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.
[0015] 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.
[0016] 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
[0027] FIG. 1 illustrates a headache diagnostic system 100
according to an embodiment of the present invention. The headache
diagnostic system 100 comprises a diagnostic file 2 and a
questionnaire sheet/form 3. While the illustrated embodiment of the
diagnostic system 100 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.
[0028] The diagnostic file 2 comprises a first overlay 20 and a
second overlay 21. The first and second overlays 20, 21 are formed
from a single piece of material that is folded in half at crease
22. Once creased, the first and second overlays 20, 21 are
connected to one another along the bottom edge 23. As a result, the
first and second overlays 20, 21 are connected along two sides,
thereby forming a pocket 24 capable of slidably receiving
questionnaire form 3 from either of the two open sides. The
connection along bottom edge 23 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. A thumbnail
cutout 25 is provided along the side of the first overlay 20 along
the open lateral side of the diagnostic file 2 so as to afford easy
separation of the first and second overlays 20, 21 during the
insertion of the questionnaire form 3. This cutout 25 can take on
any desired shape or size.
[0029] In other embodiments of the invention, the first and second
overlays 20, 21 of the diagnostic file 2 can be separate pieces of
material that are connected along one or more edges using one of
the above identified connection techniques to form the diagnostic
file 2. The overlays 20, 21 can be formed of one or more layers of
thin flexible materials, such as plastic, paper, synthetic
polymers, or the like. The diagnostic file 2 is preferably sized so
that pocket 24 fully receives a standard sized piece of paper, such
as A-4 or 8.5.times.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 a single overlay 20 or 21
may be used in combination with the questionnaire form 3 to
diagnose a medical condition. In such embodiments, the overlay 20
or 21 will be simply positioned over and aligned with the
questionnaire form 3 during use.
[0030] The questionnaire form 3 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 the
questionnaire form 3 prior to distribution in a predetermined
pattern. This will be discussed in greater detail below. The
questionnaire form 3 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, the
questionnaire form 3 can be constructed to be either disposable or
reusable. For example, in a reusable embodiment, the questionnaire
form 3 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.
[0031] Referring now to FIGS. 2A and 2B, the questionnaire form 3
is illustrated according to an embodiment of the present invention.
The questionnaire form 3 is a sheet of paper comprising screening
questions 4-5 on one side (FIG. 2A) and diagnostic questions 6-13
on the opposite side (FIG. 2B). The questionnaire form 3 is
designed with the intention that the user answer the screening
questions 4-5 on the first side before proceeding to the second
side of the questionnaire form to answer the diagnostic questions
6-13.
[0032] Referring solely to FIG. 2A, the first side 14 of the
questionnaire form 3 comprises two screening questions 4-5. While
two screening questions 4-5 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 the questionnaire
form 3, the screening questions may be omitted. In such
embodiments, the first side 14 of the questionnaire form 3 may be
identical to the second side 15 (FIG. 2B), contain different
diagnostic questions, or contain general user instructions and/or
advertisements.
[0033] A choice of corresponding answers 4A-4B and 5A-5B are
provided on the first side 14 of the questionnaire form 3 that
respectively correspond to the screening questions 4, 5. The first
side 14 further comprises instructions 16 for determining whether,
based on the user's answers to the screening questions 4-5, the
user needs to proceed with answering the next screening question
and/or the diagnostic questions 6-13 on the second side 15 of the
questionnaire form 3.
[0034] In the illustrated embodiment of the questionnaire form 3,
which is designed for migraine and/or tension-type headache
diagnosis, the screening questions 4-5 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. Regarding screening question 4
specifically, each possible answers 4A, 4B has corresponding
instructions 16 which, depending on the answer 4A, 4B selected,
will direct the user to either proceed to the next screening
question 5 or cease further completion of the questionnaire form 3.
Regarding screening question 5 specifically, each possible answers
5A, 5B has corresponding instructions 16 which will direct the user
to either proceed to answer the diagnostic questions 6-13 on the
second side 15 of the questionnaire form 3 or cease further
completion of the questionnaire form 3.
[0035] The screening questions 4, 5 are designed so that if the
user selects an answer (which in this case are answers 4B or 5B)
that correspond to instructions 16 that instruct the user to cease
further completion of the questionnaire form 3, 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 both answers 4A or 5A) that
correspond to instructions 16 that instruct the user to continue
with completion of the second side 15 of the questionnaire form 3,
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.
[0036] Referring now to FIG. 2B, the second side 15 of the
questionnaire form 3 is illustrated. Eight diagnostic questions
6-13 are provided on the second side 15 of the questionnaire form
3. The diagnostic questions 6-13 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 question 6
pertains to the frequency of which a user experiences headaches.
Diagnostic question 7 pertains to how long the user's headaches
last if no medication is taken. Diagnostic question 8 pertains to
whether the user experiences the onset of aura symptoms during
headaches, such scintillating scotomata and/or visual defect.
Diagnostic question 9 pertains to the location of the headache
pain. Diagnostic question 10 pertains to the type of headache pain.
Diagnostic question 11 pertains to the severity of the user's
headache pain. Diagnostic question 12 pertains to whether the
user's performance of certain physical activities affects/worsens
the headache pain. Diagnostic question 13 pertains to whether the
user experiences the onset of additional headache-related
symptoms.
[0037] While a total of eight diagnostic questions 6-13 are used in
the illustrated questionnaire form, the invention is not so
limited. Any combination of the diagnostic questions 6-13 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 questions 6-13 are reliable in
diagnosing migraine and/or tension-type headaches.
[0038] Each diagnostic question 6-13 has one or more possible
answers 6A-13D that correspond to the appropriate diagnostic
question 6-13. (Questions and answers having like numerical
prefixes correspond to one another.) The answer choices for each
diagnostic question 6-13 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, answers 6A and 6B correspond to diagnostic question 6. As
will be explained in detail below with respect to FIG. 5, answer 6A
is indicative of the user having migraines, while answer is 6B is
not. Some diagnostic questions 6-13 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 the
answers 6A-13D on the questionnaire form 3 are chosen so that
answers indicative of the user having the medical condition being
diagnosed are in a corresponding spatial relationship to the
windows 26 of the diagnostic file 2.
[0039] Referring now to FIGS. 3A and 3B, the first overlay 20 and
second overlay 21 of the diagnostic file 2 are illustrated in
detail. The construction of the diagnostic file 2 has already been
discussed above in relation to FIG. 1.
[0040] FIG. 3A. is a front view of the first overlay 20, which is
specifically designed for use in combination with the second side
15 of the questionnaire form 3 to diagnose migraines. The first
overlay 20 of the diagnostic file 2 comprises a plurality of
transparent windows 26 spatially arranged at predetermined
locations and designed to be a predetermined size. Each window 26
is designed so that only those answers on the questionnaire form 3
that are indicative of the user having migraines will be visible
therethrough when the questionnaire form 3 is fully inserted into
the pocket 24 with the second side 15 of the questionnaire form 3
facing the first overlay 20. While the windows 26 are transparent
sections of the first overlay 20, the windows 26 can be formed in a
variety of ways, including cutouts, etc. In some embodiments, the
entire overlay 20 may be constructed of a transparent material and
the windows 26 may be formed by boxes or other indicia marked on
the overlay.
[0041] The first overlay 20 further comprises a plurality of
diagnostic fields 27. The diagnostic fields 27 contain
criteria/instructions for diagnosing the user for migraines based
on the user's selection of answers 6A-13D on the questionnaire form
3 that are visible through the windows 26. While the diagnostic
fields 27 are illustrated as being in a separated/boxed-off areas
of the first overlay 20, the invention is not so limited. In some
embodiments, the diagnostic fields 27 may be mere areas on the
first overlay 20 containing text without any special delineation or
demarcation. Only those answers on the questionnaire form 3 that
are indicative of the user having migraines are visible through the
windows 26 of the first overlay 20 when the questionnaire form 3 is
fully inserted into the diagnostic file 2 (as shown in FIG. 5). The
diagnostic fields 27 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.
[0042] FIG. 3B. is a front view of the second overlay 21, which is
specifically designed for use in combination with the second side
15 of the questionnaire form 3 to diagnose tension-type headaches.
Similar to that of the first overlay 20, the second overlay
comprises a plurality of windows 26 and diagnostic fields 27.
However, the positioning and size of each window 26 of the second
overlay 21 is designed so that only those answers on questionnaire
form 3 that are indicative of the user having tension-type
headaches will be visible therethrough when the questionnaire form
3 is fully inserted into the pocket 24 with the second side 15 of
the questionnaire form 3 facing the second overlay 21 (as shown in
FIG. 7). Additionally, the diagnostic fields 27 of the second
overlay 21 contain criteria/instructions for diagnosing the user
for tension-type headaches based on the user's selection of answers
6A-13D on the questionnaire form 3 that are visible through the
windows 26 of the second overlay 21. Only those answers on the
questionnaire form 3 that are indicative of the user having
tension-type headaches are visible through the windows 26 of the
second overlay 21 when the questionnaire form 3 is fully inserted
into the diagnostic file 2 with the second side 15 of the
questionnaire form 3 facing the second overlay 21 (as shown in FIG.
7). The diagnostic fields 27 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.
[0043] Referring now to FIGS. 4 and 5, the method by which a user
is diagnosed with migraines using the headache diagnostic system
100 according to an embodiment of the invention will be discussed.
Starting with FIG. 4, the headache diagnostic system 100, which
includes the diagnostic file 2 and the questionnaire form 3 is
supplied to a user. In some cases, only the questionnaire form 3
will be supplied and a healthcare professional will have the
diagnostic file 2. Upon receiving the questionnaire form 3, the
user first answers the screening question 4-5 on the first side 14
of the questionnaire form 3 (as discussed above with respect to
2A). Assuming that the user answers the screening questions 4-5 so
that he/she is instructed to continue with answering the diagnostic
questions 6-13 on the questionnaire form 3, the user then turns to
the second side 15 of the questionnaire form 3. The user then reads
the diagnostic questions 6-13 and selects the answers 6A-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.
[0044] Once the user has completed selecting his/her answers 6A-13D
to the diagnostic questions 6-13, the user slides/inserts the
questionnaire form 3 into the pocket 24 of the diagnostic file 2
between the first and second overlays 20, 21, as indicated by the
arrow. The second side 15 of the questionnaire form 3 faces the
first overlay 20 at this time. The user continues to insert/slide
the questionnaire form 3 into the diagnostic file 2 until the
questionnaire form 3 is fully positioned therein (i.e., in a
diagnostic position), as shown in FIG. 5.
[0045] Referring now to FIG. 5, the components of the headache
diagnostic system 100 are arranged for migraine diagnosis, i.e.,
the questionnaire form 3 is fully and properly inserted into the
pocket 24 of the diagnostic file 2 with the first side 14 facing
the first overlay 20. As can be seen, only those answers 6A, 7C,
8A, 9A, 10A, 11A, 11B, 12A, 12B, and 13A-13D to the diagnostic
questions 6-13 that are indicative of the user having migraines are
aligned with and visible through the windows 26 of the first
overlay 20. The remaining answers to the diagnostic questions 6-13
are not aligned with the windows 26 and are not visible
therethough. Based on the user's selection of answers 6A, 8A, 9A,
10A, 11B, 12B and 13A-D to the diagnostic questions 6-13 that are
visible through the windows 26 of the first overlay, and according
to the criteria set forth in the diagnostic fields 27 of the first
overlay 20, 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 of answers 6A, 8A, 9A, 10A, 11B, 12B and
13A-D.
[0046] Referring to FIGS. 6 and 7, the headache diagnostic system
100 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 questions 6-13, the
questionnaire form 3 is inserted into the diagnostic file 2 with
the second side 15 of the questionnaire form 3 facing the second
overlay 21, as shown in FIG. 6.
[0047] FIG. 7 illustrates the components of the headache diagnostic
system 100 arranged for tension-type headache diagnosis, i.e., the
questionnaire form 3 is fully and properly inserted into the pocket
24 of the diagnostic file 2 with the second side 15 facing the
second overlay 21. When so positioned, only those answers 7B-7E,
9B, 10B-10D, 11C, 12C, and 13A-13D to the diagnostic questions 6-13
which are indicative of the user having tension-type headaches are
aligned with and visible through the windows 26 of the second
overlay 21. The remaining answers to the diagnostic questions 6-13
are not aligned with the windows 26 and are not visible
therethrough. Based on the user's selection of answers 7B, 10B, and
13A-13D to the diagnostic questions 6-13 that are visible through
the windows 26 of the second overlay 21, and according to the
criteria set forth in the diagnostic fields 27 of the second
overlay 21, 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 of answers
6A-13D.
[0048] It is important to note that the relative spatial
arrangement of the answers 6A-13D on the questionnaire form 3 and
the windows 26 on the first and second overlays 20, 21 is critical
to proper diagnosis. Moreover, it is important that the
questionnaire form 3 be fully and properly inserted into the
diagnostic file 2 so as to avoid an inaccurate diagnosis.
[0049] The headache diagnostic system 100 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 system 100 (or just the
questionnaire form 3) can be handed out to patients in the waiting
room of a hospital or other healthcare facility for completion by
the user. Using the diagnostic file 2, the doctor or other
healthcare professional can then perform the migraine diagnosis
based on the answers selected by the user on the questionnaire form
3. In other circumstances, the user can utilize the headache
diagnostic system 100 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.
[0050] In some embodiments of the invention, the questionnaire form
3 can have the diagnostic questions 6-13 on both sides 14, 15. As a
result, when the questionnaire form 3 is inserted into the
diagnostic file 2, the user and/or healthcare professional can
perform the migraine and tension-type diagnosis without having to
flip the orientation of the questionnaire form 3 in the diagnostic
file 2. 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.
[0051] Turning now to FIG. 8, a schematic of a computer based
migraine/tension-type headache diagnostic system 200 is illustrated
according to a second embodiment of the present invention. The
computer-based diagnostic system 200 comprises a display module
260, a user input device 210, a signal input port 230, a suitably
programmed microprocessor 250, and a computer memory medium 240.
The CPU 250, the memory medium 240, and the input port 230 are
located in a computer housing 220.
[0052] The CPU 250 is a suitable microprocessor based programmable
logic controller, personal computer, or the like. The CPU 250 is
electrically and operably coupled to all components of the system
200 that need to be controlled and/or communicated with. The
display module 260 can be a computer monitor or the like. The input
device 210 can be a keyboard, a mouse, a joystick, an interactive
screen, or the like.
[0053] The memory medium 240 comprises sufficient memory to store
all of the necessary computer code, algorithms, and data necessary
for the functioning of the system 200. The CPU 250 is programmed
with the proper algorithms to display an electronic version of the
questionnaire form described above on the display module 260, the
ability to facilitate the user to select answers on the electronic
questionnaire form using the input device 210, 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 the system 100, the computer based system 200 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
[0054] If desired, the CPU 250 and the memory medium 240 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. The CPU 250 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.
[0055] 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.
