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.

Claims

1. A method for identifying a cognitive condition, the method comprising:

providing a battery of tests, said battery of tests comprising at least two tests for measuring at least one of;

motor skills, visual/spatial perception, memory, information processing, verbal function and executive function;

collecting first test data from a first test from said battery of tests;

collecting second test data from a second test from said battery of tests, wherein said first test is a different test than said second test, and wherein said providing step, said collecting first test data step, and said collecting second test data step, are performed during a testing session;

norming said first test data to a reference population;

converting said first test data to a standard scale;

norming said second test data to said reference population;

converting said second test data to said standard scale; and

combining said converted and normalized first and second test data into a combined score, wherein said combined score is also on said standard scale.

2. The method of claim 1, wherein said collecting first test data and said collecting second test data comprise collecting an outcome measure, said outcome measure at least one of:

response time, level, accuracy, number of errors, sensitivity, and specificity.

3. The method of claim 1, wherein said converting said first data and and said converting said second test data comprise converting into an IQ scale.

4. The method of claim 1, wherein said providing a battery of tests comprises providing a battery of tests for MCI.

5. The method of claim 1, wherein said providing a battery of tests comprises providing a battery of tests for measuring memory and wherein said at least two tests are a verbal memory test and a non-verbal memory test.

6. The method of claim 1, further comprising dynamically adjusting levels of said at least two tests.

7. The method of claim 1, further comprising displaying said converted and normalized first and second test data and said combined score, and presenting said display to a clinician.
