Standardized medical cognitive assessment tool
First Claim
1. A diagnostic tool for determining a cognitive state of a subject, the diagnostic tool comprising:
- a battery of tests for measuring a neurological parameter;
an interface allowing a clinician to access said battery of tests and administer said battery of tests to a subject, said subject generating data in response to said administered battery of tests;
a processor for processing said generated data; and
a report generated by said processor and based on said generated data, wherein said report provides a view of said data within ranges and sub-ranges of cognitive ability.

Abstract
A testing system and method for evaluation of neurological function are provided. Specifically, the system and method can be used to differentiate between normal and pathological function for motor skills, logic, reasoning, coordination, verbal function, memory, and various other skills. In addition, it is designed to provide a package to a clinician, including a recommended battery of tests and a results report. The system and method described herein is designed to reduce bias due to the human nature of the tester, while still maintaining versatility, individualized attention and depth of analysis in testing.

9. A method for providing a report to a clinician, the method comprising:
-
obtaining an index score for a cognitive skill;
graphing said index score in relation to a set of cutoff numbers, wherein said cutoff numbers define ranges and sub-ranges of cognitive ability; and
presenting the graphed index scores in a report format to the clinician. - View Dependent Claims (12, 13, 14, 15)

16. A method for providing sub-ranges of cognitive ability, the method comprising:
-
providing a standard determination of cognitive ability to an individual;
administering a battery of tests designed to measure cognitive ability to said individual;
determining a cognitive ability of said individual based on results of said battery of tests at each of several spread values;
comparing said determined cognitive ability with said standard determination so as to collect a comparison measure at said several spread values;
repeating said providing, administering, determining and comparing until multiple comparison measures are collected;
optimizing said multiple comparison measures; and
choosing a set of cutoff spread values based on said optimization. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for determining a set of sub-ranges of a cognitive determination, the method comprising:
-
comparing data from a standard determination with data from a testing scheme;
calculating a number of false positives and false negatives from said comparison; and
choosing said sub-ranges at a point of a minimized number of said false positives, a point of a minimized number of said false negatives, and a point of best balance between said numbers false positives and false negatives. - View Dependent Claims (28, 29)
