Apparatus and method for detecting the severity of brain function impairment
First Claim
1. A method for determining the severity of brain function impairment in a person due to an insult to said brain such as mild traumatic brain injury, aging or intoxication, comprising the steps of:
- (a) determining a processing time value of said person in accordance with an elapsed time between a stimulus applied to said person and a response to said stimulus provided by said person, wherein said processing time value is representative of said impaired brain function;
(b) providing electrical signals in accordance with said processing time value, whereby said electrical signals are representative of said impaired brain function;
(c) performing mathematical operations upon said electrical signals to provide a processing time index; and
(d) determining said severity of said brain function impairment in accordance with said processing time index.

Abstract
A method for determining the severity of brain function impairment in a person due to an insult to the brain such as mild traumatic brain injury, aging or intoxication is disclosed including the steps of determining a processing time value of the person in accordance with an elapsed time between a stimulus applied to the person and a response to the stimulus provided by the person, wherein the processing time value is representative of the impaired brain function. Electrical signals are provided in accordance with the processing time value, whereby the electrical signals are representative of the impaired brain function. Mathematical operations are performed upon the electrical signals to provide a processing time index. The severity of brain function impairment is determined in accordance with the processing time index. The severity of a concussion or brain impairment can be determined quantitatively in accordance with the processing time index.
