Dr. James sits down with Dr. Mark Tommerdahl, creator of the Brain Gauge, to share how a simple vibration on your fingertips can measure your brain’s health in real time. Discover why most neurologic assessments fall short and how this technology is changing both recovery and prevention.

Frequently Asked Questions

  • The Brain Gauge app will run on any PC with Windows 8+, or any Mac with MacOS 10.10+. You will also need one available USB port.

  • The Brain Gauge is kind of like a "thermometer" for your brain. Unlike other web-based cognitive tests - which can be influenced by IQ, memory, education, and cultural factors - Brain Gauge directly measures your brain's essential physiological functions.

    Rather than measuring your ability to perform critical thinking tasks, we measure the foundational elements of brain health. Thermometers can tell you when your body temperature is outside the normal range, but without further examination they can't explain why you have a fever. Likewise, Brain Gauge can show you when your brain is functioning at its best, and when you might need to see a specialist or make lifestyle changes to optimize your cognitive performance.

  • Brain Gauge has its own replacement policy, which is handled directly through their team. If your device stops working, you can send it back to them for a replacement at no cost. If it’s lost, a new device can be purchased for $99.

    All replacements must be coordinated directly with Brain Gauge at support@corticalmetrics.com, as James Clinic does not manage this process.

  • You should be able to use your HSA card for this purchase, but it's best to confirm with your insurance provider first as each insurer has different requirements.
