Embodiment Construction

[0024] Reference is made in detail to embodiments according to the invention, examples of which are depicted in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0025] The normalized data collected has been used to create quantitative signatures of brain electrical activity that clearly distinguish normal brain function from abnormal dysfunctional conditions. This normalized data has been shown to be independent of ethnic background and to have extremely high test-retest reliability, specificity (low false positive rate) and sensitivity (low false negative rate). Studies of more than 15,000 normal and pathological assessments have demonstrated that EEG signals are highly sensitive to changes in normal brain function and are Catastrophic events of impact alter their characteristics transiently afterward, and also reflect a wide variety of chronically developing, neurological and ...

Abstract

The invention provides a method and apparatus for providing an on-site diagnosis of a subject to determine the presence and / or severity of a concussion. The method includes placing an electrode set coupled to a handheld base unit on the subject's head, acquiring brain electrical signals from the subject through the electrode set, processing the acquired brain electrical signals using a signal processing algorithm stored in a memory of the base unit, determining the presence and / or severity of a concussion from the processed signals, indicating the presence and / or severity of a concussion on the handheld base unit, and determining a course of treatment for the subject based on the indication.

Description

[0001] This application claims the benefit of US Patent Application Serial No. 12 / 041,106, filed March 3, 2008, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0002] Embodiments in accordance with the present invention relate to the field of emergency triage, and in particular to portable devices and devices for performing emergency neurological triage on a subject who has recently suffered a head injury to determine whether the subject has a concussion. method. Background technique [0003] There is a need for objective and sensitive methods of detecting subtle brain dysfunctions due to concussions. According to reports from the US military, blast concussion brain injuries are the most significant number of current casualties in Iraq and Afghanistan. However, inadequate preparation and clinical tools to identify and appropriately treat these casualties add to the data sheet of these injuries and their side effects. T...
