1. An apparatus for determining the neurological state of a subject, comprising:
- a set of electrodes configured to be placed on the subject to collect brain electrical signals;
a processor;
a memory operatively coupled to the processor, whereinthe memory stores one or more operating instructions; and
an input-output interface having at least one channel operatively coupled to the processor, whereinthe input-output interface is configured to receive brain electrical signals through the set of electrodes; and
the processor is configured to utilize the one or more operating instructions to perform one or more operations on the signals received through the input-output interface, wherein the one or more operations comprise;
de-noising the received signals;
extracting features from the de-noised signals;
classifying the extracted features; and
determining a neurological state of the subject based on the classification, wherein determining the neurological state comprises the steps of;
determining if the neurological state is normal or abnormal; and
determining if an abnormal neurological state is psychiatric or “
functional”
in nature, organic in nature, or an emergency or “
Alert”
condition.

Abstract
A method and apparatus for performing rapid brain assessment may provide emergency triage to head trauma patients by analyzing a combination of spontaneous and evoked brain potentials. The spontaneous and evoked potentials are analyzed, and the results classified, to present a real-time assessment of a patient'"'"'s brain, diagnosing any potential abnormalities therein.
