An objective, phone-based assessment. A short guided capture reads four functional brain systems, fuses them into a single calibrated index, and scores it against your own baseline. Built for concussion and TBI first.
Each test maps to specific brain circuitry. The eyes and balance rest on involuntary machinery, so a person can degrade those readings on purpose but cannot perform better than their physiology allows. That asymmetry is what makes the reading resist gaming.
Brainstem · vestibular system · cerebellum · frontal cortex
Smooth-pursuit gain (horizontal and vertical), saccade latency and velocity, vestibulo-ocular reflex gain, near point of convergence, visual motion sensitivity, and fixation stability, all from the front camera.
Vestibular · cerebellar systems
Three-stance Romberg, sway path, and center-of-mass drift from 33-point kinematics.
Prefrontal · cortical networks
Trail-making, parts A and B, with the set-shifting cost scored separately.
Sensorimotor networks
Simple reaction time with randomized inter-stimulus intervals, captured to the millisecond.
An anti-saccade prefrontal-inhibition probe is in integration, and additional involuntary channels are in active development. We label status honestly and only score what is validated.
A healthy brain keeps its systems tightly coupled: vestibular and ocular motor, postural, cognitive, and motor-timing move together. Injury pulls them apart. Concussion, TBI, and the chronic course of CTE show up as dispersion, signals drifting from one another and from the person's own baseline.
Our Dispersion-Based Cognitive Intra-Individual Variability framework turns that dispersion into one continuous, calibrated, longitudinally-comparable index. The score sits low when the systems stay coherent and rises as they drift, so lower is better, and recovery reads as a return toward baseline.
The platform pairs voluntary task performance (the cognitive screens, held stances, and reaction test) with involuntary biomarker channels (saccadic latency and velocity, smooth-pursuit and vestibulo-ocular reflex gain, gaze stability, postural micro-corrections). A person trying to under-perform a baseline degrades the voluntary channels while the involuntary ones stay physiologically anchored, and that divergence is itself a flagged signal. It is the architectural answer to the sandbagging and concealment that defeat self-report screens.
Because a capture takes only minutes, we take a series over time and build each person's own longitudinal baseline, a distribution rather than a single noisy point. Every reading is scored against that personal band, and drift out of it flags real change earlier than a symptom would.
Repeated captures reveal a person's true baseline and their day-to-day variability.
Small drift after a hit or a hard stretch stands out against the person's own history.
Decisions rest on the trend back to baseline across sessions, not one symptom-free day.
Concussion and TBI are the lead indication. The headline output is the Concussion Likelihood Index, a continuous score calibrated to each person's own baseline. A separate longitudinal index tracks the trajectory of that score across repeated captures. It does not diagnose CTE, which remains confirmable only at autopsy.
A continuous dispersion score. It sits low when your systems stay coherent and rises as they drift apart, tracked over time against your own baseline.
A family of calibrated indices extends from the same capture, a per-person sensitivity profile, a return-to-play and duty threshold, and severity and longitudinal-risk indices, on the roadmap as validation matures.
Not seventeen unrelated ideas. One method, anchored on concussion and TBI and protected in layers: the scoring foundation, the signals that feed it, and the broader platform it extends into.
U.S. provisional patent applications filed. No claim is made that any application has been granted, nor that any claim is allowable. Patent prosecution is ongoing.
The platform is research-stage and under active validation. Pilot collaborations, cohort partnerships, and trial endpoints are open to discussion. Decision-support, not a diagnosis.
