Brainscope Ahead 200

The BrainScope Ahead 200 is a portable EEG device designed to assist clinicians in evaluating patients with recent mild traumatic brain injury by providing an objective measure of brain electrical activity. Utilizing quantitative EEG analysis from frontal electrodes and a proprietary "Harmony" algorithm, it aims to identify patients unlikely to have CT-visible structural brain injuries, thereby aiding decisions regarding the necessity of head CT scans.

The BrainScope Ahead 200 (models M-200 and CV-200) is a portable, non-invasive electroencephalogram (EEG) device designed to aid in the evaluation of patients aged 18-80 years who have sustained a closed head injury within the previous 24 hours and clinically present with a mild traumatic brain injury (Glasgow Coma Scale score of 13-15). It serves as an adjunctive tool to standard clinical practice for assessing whether these patients should undergo a head CT scan, but it is not a replacement for a CT scan. The M-200 model, intended for military use, additionally includes functionality to store and display the Military Acute Concussion Evaluation (MACE), while the CV-200 is for civilian use; both share the same core EEG technology and indications for use. The device operates by recording, measuring, and analyzing brain electrical activity from frontal electrode locations on the patient's forehead using quantitative EEG (qEEG) techniques. It calculates and displays standard qEEG parameters such as Absolute and Relative Power, Asymmetry, Coherence, and Fractal Dimension, which are available for post hoc analysis by qualified users. The core "Harmony" algorithm processes this EEG data to provide a "BrainScope Classification." A negative classification suggests brain electrical activity consistent with no structural brain injury visible on a head CT, whereas a positive classification indicates brain electrical activity that could be present in patients both with or without a CT-visible structural injury, and does not confirm such an injury. The Ahead 200 features enhancements such as improved signal noise immunity, continuous electrode impedance monitoring during recording, and a user-friendly dashboard for real-time EEG recording feedback.

• Q1. What is the sensitivity and specificity of the "BrainScope Classification" in predicting the absence of CT-visible structural brain injury in the indicated patient population (18-80 years, GCS 13-15, within 24 hours of injury)?; How does the performance of the "Harmony" algorithm in the Ahead 200 compare to its predecessor (Ahead 100), particularly considering the hardware improvements like better Common Mode Rejection Ratio (CMRR) and Analog-to-Digital Converter (ADC) location?; What specific quantitative EEG (qEEG) patterns or thresholds contribute most significantly to a "positive" versus "negative" BrainScope Classification, and are these patterns well-established biomarkers for TBI-related structural injury?; In clinical practice, what is the observed reduction in unnecessary head CT scans when using the Ahead 200 as an adjunctive assessment tool for mild traumatic brain injury?; Are there any studies comparing the utility of the raw qEEG measures (Absolute/Relative Power, Asymmetry, Coherence, Fractal Dimension) provided by the Ahead 200 with the binary "BrainScope Classification" for clinical decision-making or prognostic assessment in mild TBI?
