BrainScope One is a multi-modal, multi-parameter assessment indicated for use as an adjunct to standard clinical practice to aid in the evaluation of patients who have sustained a closed head injury within the past 72 hours (3 days), are between the ages of 18-85 years, have a Glasgow Coma Scale (GCS) score of 13-15 (including patients with concussion / mild traumatic brain injury (mTBI)), and are being considered for a head CT. BrainScope One should not be used as a substitute for a CT scan.
The BrainScope One Structural Injury Classification (“SIC”) uses brain electrical activity to determine the likelihood of structural brain injury visible on head CT. Negative likely corresponds to those with no structural brain injury visible on head CT. Positive likely corresponds to those with a structural brain injury visible on head CT. Equivocal may correspond to structural brain injury visible on head CT or may indicate the need for further observation or evaluation.
BrainScope One provides a measure of brain function (EEG Brain Function Index, (BFI)) for the statistical evaluation of the human electroencephalogram (EEG), aiding in the evaluation of head injury as part of a multi-modal, multi-parameter assessment.
The BrainScope One device is intended to record, measure, analyze, and display brain electrical activity utilizing the calculation of standard quantitative EEG (QEEG) parameters from frontal locations on a patient's forehead. The BrainScope One calculates and displays raw measures for the following standard QEEG measures: Absolute and Relative Power, Asymmetry, Coherence and Fractal Dimension. These raw measures are intended to be used for post hoc analysis of EEG signals for interpretation by a qualified user.
BrainScope One also provides clinicians with quantitative measures of cognitive performance to aid in the assessment of an individual's level of cognitive function. These measures do not interact with any other device measures, and are stand alone.
BrainScope One also stores and displays electronic versions of standardized clinical assessment tools that should be used in accordance with the assessment tools’ general instructions. These tools do not interact with any other device measures, and are stand alone.
Indications for use as stated in the FDA summary.
