No. BrainAge is an exploratory wellness tool. It produces a measurement of your brain function and compares it to age-matched norms, but it doesn't diagnose any medical condition, predict any disease, or replace a clinical evaluation. If you have a clinical concern about your mental health or cognition, a BrainAge scan is not the right starting point — see a psychiatrist or neurologist first.

The device uses time-domain functional near-infrared spectroscopy (TD-fNIRS) — near-infrared light shone through the scalp to measure blood flow and oxygenation across the cortex. Kernel's machine-learning model processes 187 characteristics of your brain activity to generate your BrainAge score. No radiation, no needles, no enclosed space. The underlying TD-fNIRS technology has peer-reviewed validation; Kernel's specific BrainAge scoring publication is in preparation.

It happens, and it doesn't automatically mean anything is wrong. Two technical facts worth knowing: the BrainAge model has a mean absolute error of about 8.5 years, and it's known to skew older for younger participants and younger for older ones — a documented limitation across all current functional brain age models. So a score four or five years off your chronological age sits within normal model variability, not a signal of anything specific. Beyond the math, ordinary day-to-day factors — stress, sleep, illness, medication — can move the number too. A single scan is one data point. If a number is meaningfully concerning to you, the next step isn't another scan; it's a conversation with a clinician. We have one on-site.

Many of our patients do. Common pattern: scan before starting a treatment course, scan again after the course ends, and a third time three to six months later. Each scan is $50. We keep your history on file. Note that BrainAge wasn't designed specifically to measure TMS response — your symptom improvement, tracked by standard clinical scales, is the more important measure.

The scan itself takes about seven minutes. Results are processed by Kernel and emailed to you, usually within a few days. The report includes your overall BrainAge score, your five domain percentiles, and a brief plain-language explanation of what the numbers mean.

BrainAge isn't a billable medical service. It's a wellness measurement, not a clinical diagnostic. Commercial and government insurers don't cover wellness scans, and we don't submit them for reimbursement. The flat $50 price is what you pay.

Kernel Flow uses near-infrared light at intensities consistent with established fNIRS research and consumer applications. No radiation, no contraindications around metal implants like with MRI, no claustrophobic enclosure. The device is comfortable to wear for the seven-minute scan duration. There are no recovery requirements — you walk in, scan, and leave.

Optimum is led by Dr. Mark Blair, an ABPN board-certified psychiatrist with over 24 years in practice. He's a US Air Force veteran, founded Optimum TMS in 2017, and personally oversees clinical operations. For BrainAge specifically, scans are administered by trained staff; results that raise clinical concerns can be reviewed with Dr. Blair or one of our psychiatric nurse practitioners.
