The mind, measured —not just described.

Validated self-assessments, EEG and fNIRS from any headset, continuous body metrics and every medication or therapy, aligned on one timeline and written up as clinical-grade reports. Objective analysis behind every diagnosis and treatment decision you make.

Mental health diagnosis still runs on self-report. Two patients can describe the same symptoms and get two different diagnoses, and the wrong one means months or years of trial-and-error treatment in a $460 billion healthcare system.

6yrs

Median delay to an accurate bipolar diagnosis. Drancourt et al., Acta Psychiatr Scand (2013)

Not just bipolar: ADHD and autism are diagnosed late, too

56%

of U.S. adults with ADHD were first diagnosed at 18 or older. CDC, MMWR (2024)

3.9yrs

later ADHD diagnosis for females than males (23.5 vs. 19.6 years). Skoglund et al., J Child Psychol Psychiatry (2024)

47mo

median age of autism diagnosis, though it can be identified far earlier. CDC ADDM Network, MMWR (2025)

1 in 31 U.S. 8-year-olds has autism, and about 1 in 9 U.S. children has been diagnosed with ADHD.CDC ADDM Network, MMWR (2025); Danielson et al., J Clin Child Adolesc Psychol (2024)

Four channels.
One objective record.

Every treatment, self-report, brain recording and body metric lands on the same patient timeline, so you can see what changed in mind and body, and what changed it.

Medication & therapy: Everything that could change the picture

Log treatments from traditional to experimental medications, and therapies from a morning cold plunge to yoga or meditation. Each one marks the timeline, so the other three channels can be read before and after it.

Medications
Traditional or experimental
Therapies
Short-term psychotherapy, all modalities, long-term psychotherapy
Alternative therapies
Ketamine, peptides, psilocybin…
Treatment windows
Historical and current

Assessments: A full clinical library

Biometrics: Continuous body metrics

Passive physiological data, captured twice daily, so treatment response shows up between visits.

Oura Ring
Sleep, HRV, readiness
WHOOP
Recovery, HRV, strain
Google Health / Fitbit
Sleep, HRV, resting HR
Withings
Body mass, blood pressure

Then ask the timeline anything. Run a Patient Trend Analysis over any date range: choose the channels, add your own clinical question, and AI models trained with our on-staff neurologists and clinicians report what changed and what changed alongside it.

Did the treatment work?
The timeline knows.

Ask about a medication, a new therapy or anything else on the record. A Patient Trend Analysis compares the weeks before and after, across assessments, qEEG and body metrics that arrive twice a day, without waiting for the next follow-up.

Illustrative patient · baseline to week 12 Anxiety score Sleep recovery qEEG session Treatment
Medication started Baseline Week 4 Week 6 Week 8 Week 12 Sleep recovery rising Anxiety falling Medication started Baseline Week 6 Week 12
Week 6 to week 12After the medication change, the anxiety score trends down while physiological sleep recovery climbs, visible between visits.

Any headset.
A clinical-grade report.

From a consumer headband with fNIRS to a 20-channel clinical headset, every eyes-closed / eyes-open session becomes a structured Neurophysiology Analysis. Two de-identified samples:
