Embodiment Construction

[0018] Reference will now be made in detail to certain embodiments consistent with the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0019] In an exemplary embodiment, data corresponding to electrical brain activity is used to detect neurological injury or disease in a patient. Electroencephalogram signals are measured and analyzed using a portable neuroassessment device at the point of care. In an exemplary embodiment of the present disclosure, a subject's brain electrical activity is recorded using a varying number of electrodes at standardized locations on the scalp and forehead, and the subject's brain electrical signals are evaluated with reference to one or more databases . For example, collected canonical data indicative of normal brain electrical activity is used to establish a quantitative signature of brain e...

Abstract

A device and method for assessment of traumatic brain injury (TBI) is described. The device is configured to acquire brain electrical signals from a patient's forehead using one or more neurological electrodes. The acquired brain electrical activity data is subjected to artifact rejection and feature extraction, and a subset of features are then combined in at least one classifier function. The classifier functions statistically place a patient in one of four categories related to the extent of brain dysfunction: 1) normal brain electrical activity; 2) abnormal brain electrical activity consistent with non-structural injury with less severe manifestations of functional brain injury; 3) abnormal brain electrical activity consistent with non-structural injury with more severe manifestations of functional brain injury; and 4) abnormal brain electrical activity consistent with structural brain injury.

Description

technical field [0001] The present disclosure relates to the field of neurological assessment, and in particular, to a portable handheld device and method for performing neurological triage of patients at the point of care. Background technique [0002] The brain executes the most complex and substantial processes in the human body. Surprisingly, contemporary health care lacks well-established tools to objectively assess brain function at the point of care. The patient's mental and neurological status is usually assessed by interview and subjective physical examination. Clinical laboratories do not currently have the ability to assess brain function or pathology other than to help identify poisons, toxins, or drugs that may affect the central nervous system (CNS) externally. [0003] Brain imaging studies, such as computed tomography (CT) and magnetic resonance imaging (MRI), are widely used to visualize brain structures. However, CT scans and MRIs are anatomical tests an...
