Neuorological condition detection unit and method of using the same
First Claim
1. A method for detecting a neurological condition comprising:
- attaching evoked electrodes on opposite sides of a body so that a first evoked electrode is positioned on a left side of the body and a second evoked electrode is positioned on a right side of the body at a position that corresponds to where the first evoked electrode is positioned on the left side of the body;
positioning sensors on the opposite sides of the body via headgear to simultaneously position the sensors on the body to detect brain reaction to electrical current passed into the body for a pre-selected number of shocks,communicatively connecting the evoked electrodes and the sensors to a computer device having non-transitory memory connected to a processor;
positioning a reference sensor on the body so that the reference sensor is located on a central region of a forehead at a location that is between a first sensor of the sensors that is positioned on a left side of a head of the body and a second sensor of the sensors that is positioned on a right side of the head of the body; and
the computer device utilizing the reference sensor to determine that at least one of the sensors needs to be re-positioned so that the sensors on opposite sides of the body have a pre-selected orientation;
the computer device determining that at least one of the sensors needs to be re-positioned so that the sensors on opposite sides of the body have the pre-selected orientation and outputting an orientation warning to indicate at least one of the sensors needs to be repositioned for sensor orientation for repositioning at least one of the sensors on the body;
after the at least one of the sensors is repositioned for sensor orientation based on the orientation warning output by the computer device, shocking the body via the evoked electrodes for the pre-selected number of shocks within a pre-selected time period, the computer device transmitting the electrical current to the evoked electrodes for the shocking of the body via the evoked electrodes, wherein the shocking of the body via the evoked electrodes for the pre-selected number of shocks within the pre-selected time period comprises passing an electrical current into the body via an electricity transmitter of the computer device that is connected to the evoked electrodes;
the sensors positioned on the opposite sides of the body detecting data from the body as the body responds to the pre-selected number of shocks;
the computer device receiving the detected data from the sensors;
the computer device generating at least one of wave forms and curves that identify morphological features for responses from the pre-selected number of shocks that the opposite sides of the body are measured to have based on the detected data received from the sensors;
the computer device comparing the morphological features to determine a difference between a morphological feature for the left side of the body and a morphological feature for the right side of the body that is at or exceeds a pre-selected threshold that is defined to indicate the left side of the body has a different somatosensory evoked potential responding to the shocks as compared to the right side of the body responding to the shocks for indication of a neurological condition requiring treatment, the neurological condition requiring treatment being a stroke; and
the computer device generating a notification to identify a detection of the neurological condition in response to a result of the comparing of the morphological features indicating that the difference between the morphological feature for the left side of the body and the morphological feature for the right side of the body is at or exceeds the pre-selected threshold so that the neurological condition is identifiable prior to transporting the body to a care facility.

Abstract
A neurological condition detection unit can include a computer device that is connected to at least two leads that are connectable to a patient for evoking a response from that patient via an electrical current passed through the leads (e.g. a shock) and at plurality of sensors connected to the computer device to sense how the left side and right side of the patient'"'"'s brain reacts to the evoked event (e.g. the shock). The stroke detection device and/or neurological condition detection unit can be configured to output a warning when one side of the patient'"'"'s brain is determined to react differently than the opposite side of the patient'"'"'s brain by at least a pre-selected threshold value. The warning can include an identification of a nearby care facility that may be best suited for providing care to a patient determined to have a neurological condition (e.g. a stroke).
