A private tool to help players, parents, and former athletes document a hockey career's worth of head-impact exposure — and decide whether to talk to a doctor.
Please read first. This is not a medical diagnosis and not a medical device. It organizes your exposure history and symptoms into a research-based estimate for discussion with a clinician. It cannot tell you whether you have a brain injury, and a low estimate is not an all-clear.
CTE can only be diagnosed after death. This app does not detect, predict, or rule out CTE — it's a starting point for a conversation with your physician.
In crisis? Call or text 988 (Suicide & Crisis Lifeline), available 24/7.

Document your exposure. Screen your symptoms. Bring a one-page summary to your doctor.
Rate how much each has bothered you in the past month — 0 = not at all, 4 = very severe. These domains come from the tools clinicians use to screen for concussion effects.
The more accurately you can reconstruct this, the more useful the estimate. Best guesses are fine.
How this was calculated
This is a relative estimate of documented head-impact exposure compared to the ranges seen in published research — not a probability of disease and not a diagnosis. It exists to help you decide whether to raise this with a clinician.
Generate a one-page summary of your exposure, symptoms, and estimate to bring to a medical appointment.
The model is grounded in published head-impact research. Key inputs and their basis:
The specific research inputs, weighting and calibration used to produce this estimate are proprietary to Continuum Improvement LLC. The complete methodology and reference list is available on request from support@continuumimprovement.com.
Symptom screen adapted from published post-concussion symptom inventories. This is a screen, not the validated clinical instrument, and not a diagnosis.
