Abstract:
An improved method for pre-screening for underlying physiological conditions prior to psychiatric assessment. The method comprises the steps of administering a predetermined battery of tests including blood tests, urine tests and genetic tests, entering test results in a form, and differentially correlating the entered test results to underlying physical conditions relevant to a symptomatic psychiatric disorder. The pre-screening allows a correct diagnosis of the physical condition rather than a misdiagnosis of some neurological condition that is merely symptomatic of the physical condition. The invention may be implemented in a computer architecture using software.

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
       [0001]    The present application derives priority from U.S. Provisional Patent Application No. 61/512,618 filed 28 Jul. 2012. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to improvements in psychiatric patient screening and diagnosis and, particularly, to a method for psychiatric assessment by pre-screening for underlying neurotoxic disorders, metabolic/endocrine disorders, genetic issues, disease and other physical root causes of psychiatric disorder, and correlation of underlying physical conditions to said psychiatric disorder. 
         [0004]    2. Description of the Background 
         [0005]    A psychiatric assessment, or psychological screening, is a process of gathering information about a person within a psychiatric (or mental health) service, with the purpose of making a diagnosis. The assessment is usually the first stage of a treatment process. Such assessments are often inconclusive and only lead to more comprehensive psychiatric testing. It is well-recognized that many psychiatric disorders are often caused by underlying physiological problems such as neurotoxic disorders, metabolic/endocrine disorders, genetic issues, disease and the like. However, typical treatment of psychiatric illness assumes that the illnesses with similar symptoms have similar causes and that there are only a few causes of psychiatric illness. That is not true. In some cases, during a battery of psychiatric testing, the results will begin to point to some underlying physiological cause. However, this often takes a great deal of physician skill and experience to recognize and pursue this line of thinking. 
         [0006]    There are many post-screening approaches to correlate specific psychiatric symptoms to particular physical issues when neurologic findings are not conclusive. 
         [0007]    For example, Brett et al., “Screening For Vitamin B12 Deficiency In Psychiatric Patients”, J Gen Intern Med. 1994 September; 9(9):522-4 explains how psychiatric patients are frequently screened for vitamin B12 deficiency in the absence of hematologic or other neurologic findings. The authors suggest post-screening for vitamin B12 deficiency in the absence of hematologic or other neurologic findings. 
         [0008]    At least three companies—Neuromark, Psynomics, and SureGene—are offering genetic tests for variants associated with mental illness. Neuromark&#39;s Mark-C test examines two genetic markers, GRIK2 and GRIA3, that appear to increase the risk of suicidal thoughts in people taking antidepressant drug Celexa™. Psynomic&#39;s Psynome™ tests for two mutations in the GRK3 gene associated with bipolar disorder. SureGene™ has developed the AssureGene™ test that examines a panel of (unspecified) genes and markers that is being marketed to aid in the diagnosis of patients at risk of developing psychosis. 
         [0009]    The concept of pre-screening for physiological root causes has been discussed generally. Garden, Gill, “Physical examination in psychiatric practice”, Advances in Psychiatric treatment, 11: 142-149 (2005) suggests that a thorough physical examination should be an integral part of a comprehensive psychiatric assessment because physical illnesses are more common in people with mental disorders. However, Gill merely suggests a somewhat nebulous series of tests with no proximate correlation to neurological systems. 
         [0010]    Other physiological approaches to psychiatric assessment include United States Patent Application 20100009325 by Afanasiev et al. which shows a psychological method for testing or subconsciously teaching a subject by visual subconscious stimulus. 
         [0011]    U.S. Pat. No. 6,053,866 to McLeod issued Apr. 25, 2000 shows a method for facilitating diagnosis of a psychiatric disorder by questionnaire in a format which facilitates recording the patient&#39;s answers and establishing a preliminary disorder indication based on the answers. 
         [0012]    U.S. Pat. No. 6,245,021 to Stampfer (HeartLink) issued Jun. 12, 2001 shows a method for diagnosing psychiatric disorders comprising the steps of measuring the pattern of a subject&#39;s heart rate, and using said pattern to diagnose the psychiatric disorder. Also disclosed is a method for assessing the effectiveness of a treatment for a psychiatric disorder, comprising measuring a heart rate pattern of a subject before treatment, measuring a heart rate pattern of the subject during treatment, and comparing the patterns for changes to determine the effectiveness of the treatment. 
         [0013]    United States Patent Application 20080124688 by Kay published May 29, 2008 shows an automated protocol for determining psychiatric disability based on various assessments (stress, social, activity) and combining the results to determine psychiatric status. 
         [0014]    To illustrate the problem, vitamin deficiency is linked to psychiatric symptoms but the result is usually sub-clinical, meaning that vitamin levels are too low to maintain proper health, but sufficient to prevent classic clinical symptoms of deficiency. Moreover, vitamins interact with each other and an imbalance may not be attributable to any one vitamin. This makes it difficult for a clinician to detect such deficiencies when they exist, and virtually impossible when the clinician is a psychiatrist looking for the cause of mental symptoms. Having a blood test is the definitive way of detecting vitamin deficiencies, but in a psychological setting this is often a last resort. It would save time, trouble and considerable expense to deliver a battery of physiological tests prior to a standard psychiatric evaluation, if only the results could be adequately correlated to neurological disorders. None of the foregoing references proposes an extensive battery of physiological testing prior to a standard psychiatric evaluation, and a software tool for concrete correlation of the battery results to prescreen for neurological disorder. What is needed is a predetermined battery of tests to yield a matrix of physiological test results, and a weighted analysis/correlation of said matrix to neurological diagnoses that is capable of software implementation. 
       SUMMARY OF THE INVENTION 
       [0015]    It is, therefore, an object of the invention to provide a system and method of psychiatric assessment by pre-screening for underlying neurotoxic disorders, metabolic/endocrine disorders, genetic issues, disease and other physical root causes of psychiatric disorder, and a software tool for correlation of underlying physical conditions to said psychiatric disorder. 
         [0016]    It is a more specific object to provide a predetermined battery of tests to yield a matrix of physiological test results, plus a weighted analysis/correlation of said matrix to neurological diagnoses that is capable of software implementation. 
         [0017]    In accordance with the foregoing object, the present invention provides an improved method for pre-screening for underlying physiological conditions prior to psychiatric assessment. The method comprises the steps of administering a predetermined battery of tests including group of blood, urine, stool and hair tests that are designed to detect physiological causes of psychiatric illness, entering test results in a database, and differentially correlating the entered test results to underlying physical conditions relevant to a symptomatic psychiatric disorder. The pre-screening allows a correct diagnosis of the physical condition rather than a misdiagnosis of some neurological condition that is merely symptomatic of the physical condition. The invention may be implemented in a computer architecture using software.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0022]    Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. 
         [0023]    The present invention is a method of pre-screening for underlying neurotoxic disorders, metabolic/endocrine disorders, genetic issues, disease and other physical root causes prior to a psychiatric assessment. The method entails administering a predetermined battery of tests to yield a matrix of physiological test results. The matrix of physiological test results is subjected to a deductive analysis using weighted scoring and is automatically correlated to specific neurological diagnoses. The entire method is capable of software implementation using a rule-based artificial intelligence engine. 
         [0024]    The invention is herein implemented in the context of an application service provider (ASP) computer network to facilitate client use of the present method in software form. 
         [0025]    As shown in  FIG. 1 , ASP network  10  may include a plurality of clients  12  and servers  14  connected via the internet  11 . Any number of clients  12  and servers  14  may participate in such a network  10 . The system further includes at least one ASP local area network  17  (“LAN”) for hosting and allowing administration of the system by administrators using ASP clients. The internet or World Wide Web provides a known system for interconnecting clients  12 , servers  14  and ASP LAN  17  in a communicating relationship. However, other networks may be used, such as satellite networks, the Public Switched Telephone Network, WiFi networks, WiMax networks, cellular networks, and any other public, private, or dedicated networks that might be used to interconnect devices for transfer of data. 
         [0026]    Physician users will typically access the system via a client  12 , and an exemplary client  12  may include a processor, a memory (e.g. RAM), a bus which couples the processor and the memory, a mass storage device (e.g. a magnetic hard disk or an optical storage disk) coupled to the processor and the memory through an I/O controller, and a network interface coupled to the processor and the memory, such as a modem, digital subscriber line (“DSL”) card, cable modem, network interface card, wireless network card, or other interface device capable of wired, fiber optic, or wireless data communications. One example of such a client  12  is a personal computer equipped with an operating system such as Microsoft Windows, UNIX, or Linux, along with software support for Internet communication protocols. The client  12  preferably includes at least one browser program, such as Microsoft Internet Explorer, Google Chrome™, Netscape Navigator™, FireFox™ or the like to provide a user interface for access to the software. 
         [0027]    Corporate (hospital or other health care provider) users will typically access the system via a server  14 , and an exemplary server  14  includes a processor, a memory (e.g. RAM), a bus which couples the processor and the memory, a mass storage device (e.g. a magnetic or optical disk) coupled to the processor and the memory through an I/O controller, and a network interface coupled to the processor and the memory. Servers may be clustered together to handle more client traffic and may include separate servers for different functions. Such servers may further include one or more mass storage devices such as a disk farm or a redundant array of independent disk (“RAID”) system for additional storage and data integrity. Suitable servers and mass storage devices are manufactured by, for example, Compaq®, IBM®, and Sun Microsystems®. Server  14  runs an enterprise operating system such as Sun®, Oracle Solaris® or the like, and uses a standard HTTP server, such as Apache®. 
         [0028]    ASP LAN  17  comprises a plurality of ASP clients  13  clustered together to handle more client traffic and including one or more mass storage devices such as a disk farm or a redundant array of independent disk (“RAID”) system for additional storage and data integrity. The ASP local area network  17  (“LAN”) interconnects ASP clients  13  through a hub  15  (for example, a peer network such as a wired or wireless Ethernet network) or a local area network server (in, for example, a client-server network). The ASP LAN  17  is preferably connected to the internet  11  through a secure gateway  16 , which provides HIPPA-compliant security to the ASP LAN  17  and ensures operating compatibility between the ASP LAN  17  and the internet  11 . An exemplary ASP client  13  may include a processor, a memory (e.g. RAM), a bus which couples the processor and the memory, a mass storage device (e.g. a magnetic hard disk or an optical storage disk) coupled to the processor. The present invention is data intensive, and at least one ASP server  18  in ASP LAN  17  is a database server running database management software to provide database services to ASP LAN  17  and user clients  12  and servers  14 , as defined by the ASP client-server model. Database management systems frequently provide database server functionality, and some DBMSs (e.g., MySQL) rely exclusively on the client-server model for database access. Thus, ASP server  18  preferably hosts a network database preferably an SQL server database, running MySQL. Other examples of Database servers are Oracle, DB2, Informix, Ingres, SQL Server. Secure communication lines are used between clients  12 , servers  13  and ASP LAN  17  so that private data remains so. 
         [0029]    The secure gateway  16  may be a Citrix Access Gateway® for securing the delivery of healthcare information and populating data to user clients  13  and servers  14  anywhere. Gateway  16  provides security to the ASP LAN  17  and ensures operating compatibility between the ASP LAN  17  and the internet  11 . 
         [0030]    The ASP server  18  hosts a hosts a web server which delivers data-entry capability to the software by transmitting web pages in hypertext markup language (HTML) or extensible markup language (XML) (or a similar scheme) using the hypertext transport protocol (http) to any of clients  12 ,  13  or servers  14 . The physician administers the predetermined battery of tests (described below) and enter the results in a spreadsheet-like matrix of physiological test result data stored in ASP server  18  network database. The ASP server  18  also hosts the analytical rules-based decision engine of the present invention, plus a network SQL database which is populated with the rules employed by the decision engine, as will be described. Data extracted from other health-related databases may be used to populate the SQL database. When data entry of the physiological test results is complete, the analytical rules-based decision engine subjects said results to a weighted analysis using the SQL database rules, and correlates the test results to specific neurological diagnoses. 
         [0031]    The method of the present invention will now be described in detail. Physician users administer the predetermined battery of tests and enter the results via client  12  in a spreadsheet-like  matrix of physiological test result data stored on ASP server  18  in its network database. 
         [0032]    The battery of physiological tests comprises at least the following categorical tests: blood testing, urine testing, stool testing, and genetic screening by a hair sample. Each test including one or more different assays looking for different markers, each marker being clinically relevant to one or more known neurological conditions. As an initial step, blood and urine, plus a stool and hair sample must be collected. For this purpose each patient is supplied with a urine/stool/hair collection kit, and blood will be drawn from a vein in the arm using a needle, or via finger prick. Given the requisite samples the following tests and assays are performed.

         [0143]    Tay-Sachs Disease (TS; fatal neurological disease of early childhood; seizures, paralysis) 
         [0144]    Thalassemias (THAL; anemias—reduced red blood cell levels) 
         [0145]    Timothy Syndrome (CACNA1C; characterized by severe cardiac arrhythmia, webbing of the fingers and toes called syndactyly, autism). 
         [0146]      FIG. 2  is a screen print of an exemplary data entry form page for some of the above-described battery of physiological tests including blood testing, urine testing, hair and stool screening, and optionally genetic screening, each test including one or more different assays looking for different markers each clinically relevant to a known neurological condition. 
         [0147]    After the physician administers the test battery and enters the results in the spreadsheet of  FIG. 2 , the ASP server  18  applies the analytical rules-based decision engine, using the ruleset stored in the network SQL database, to differentially screen for an underlying physical root cause of a neurological condition. 
         [0148]    A unique aspect of the present invention is the method for correlating the observed complementary assay results of the physiological tests including blood testing, urine testing, hair and stool screening, and optionally genetic screening, to neurological symptoms of a patient. This is a two-step analysis, the ASP server  18  software first being configured to collect and receive the observed assay results of the patient and to correlate the observed assay results to physical symptoms which may include increase in blood pressure, increase in heart rate, increase in temperature, toxicity, increase in blood sugar level, decrease in oxygen in the blood, decrease of brain or motor activities, respiratory effects, chest pains and/or other symptoms that may be observed. The ASP server  18  software is configured to make a secondary correlation of the physical symptoms to neurological symptoms of the patient. The complementary assay results of the select blood testing, urine testing, hair and stool screening, and optionally genetic screening provide a more reliable indication of the root physiological cause of neurological symptoms and allow a very reliable pre-screening for physiological causes of psychiatric disorders. 
         [0149]    For example, the pH of urine can vary between 4.6 and 8, with 7 being norm. In persons with hyperuricosuria, acidic urine can contribute to the formation of stones of uric acid in the kidneys, ureters, or bladder. The ASP server  18  applies the analytical rules-based decision engine to correlate a high urine pH observed by the urinalysis and presence of kidney stones in the stool sample to a build-up of uric acid in all body fluids, and to correlate the physiological symptoms to observed neurological symptoms including poor muscle control, facial grimacing, involuntary writhing, and repetitive movements of the arms and legs, resulting in physiological diagnosis of a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT). 
         [0150]    Thus, as seen in  FIG. 2  the ASP server  18  analytical rules-based decision engine includes a complete list of conditions (column 1) having a physiological origin, associated with the specific observed assay results of the patient (columns 2-4) which serve as indicators for that condition, a status column (column 5) indicating completion status of the associated assay, and the physiological illnesses (column 6) that correlate the conditions of column 1 with the indicators of columns 2-4, thereby associating one or more assay results with one or more conditions, and one or more conditions with one or more specific neurological illnesses. 
         [0151]    Using the spreadsheet of  FIG. 2  to provide a specific example, it can be seen that the urine test for Nicotinic acid was positive, and low levels of vitamin B3 were found in the blood tests. The analytical rules-based decision engine is preprogrammed to recognize that a deficit of vitamin B3 (or the amino acid tryptophan, which is converted into niacin) is differentially confirmed by Nicotinic acid in the urine. Both are present indicators in the spreadsheet of  FIG. 2 . The decision engine populates the marker field (column 6) with the physical condition and the associated neurological symptoms, in this case the condition being pellagra, and the neurological symptom being dementia. A corrective action may be stated in the notes, e.g., “treat with niacin supplements.” 
         [0152]    The ruleset stored in the network SQL database comprises a library of clinical guidelines for differentially completing a diagnosis in accordance with the entered data. The analytical engine is a rule-based table of if-then type statements regarding specific conditions. 
         [0153]      FIG. 3  is an example of entries in the Differential Diagnosis Ruleset used by the analytical engine of the present invention. 
         [0154]    In addition, inferences are preferably weighted pursuant to a Likert scale applied to each inference (1=100% certain; 2=Somewhat certain; 3=Neutral; 4=Somewhat uncertain; 5=unclear). The Likert scale may be used to validate the existence of a particular condition to 100% certainty according to clinically accepted standards. 
         [0155]    Had the above-described physician begun with a psychiatric assessment, or psychological screening for the purpose of making a diagnosis, they would find dementia and begin more comprehensive psychiatric testing to determine the cause. The physician would not have considered potential underlying physiological problems unless as a last resort, and even then it would have required significant skill and experience to recognize and pursue this line of thinking As a result, a mis-diagnosis would have been likely to result. 
         [0156]    It should now be apparent that the above-described invention provides more efficient and effective methods of psychiatric assessment by pre-screening for underlying physical conditions related to psychiatric disorders, via a predetermined battery of tests to yield a matrix of physiological test results, plus a weighted analysis/correlation of said matrix to neurological diagnoses that is capable of software implementation. The present invention is based on the premise that psychiatric disorders are often caused by underlying physiological problems such as neurotoxic disorders, metabolic/endocrine disorders, genetic issues, disease and the like, and that a differential (blood, urine, genetics) physical examination should be an integral part of a comprehensive psychiatric assessment. 
         [0157]    Those skilled in the art will understand that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is to be understood, therefore, that the invention may be practiced otherwise than as specifically set forth in the appended claims.
