Tabula Attentiva measures what a clinician can't catch by eye: reaction-time variability, effort validity, and change across visits. Built for the primary-care and neurology office, and normed to a child's exact age so immaturity isn't mistaken for a disorder.
A symptom checklist is fast and cheap — and anyone who has read about ADHD can produce the right answers. A full neuropsychological battery is rigorous — and out of reach for most families. Tabula Attentiva is the missing middle: objective, repeatable, and fast enough to run at the point of care.
Measures reported symptoms, not performance. No way to tell genuine difficulty from a coached or exaggerated profile.
Performance markers plus built-in effort checks, in about 20 minutes. Defensible data without a referral, and a clear triage signal for who needs more.
The thorough option, at $2,500–5,000 and waitlists of weeks to months. Reserved for complex cases — most people never reach it.
A clinician reads it as: Attentiva measures → Critica checks → Lucida explains. Bundle complementary tasks into a single visit; re-run at each follow-up to track whether treatment actually helps.
Age-appropriate attention tasks — picture stimuli for young children, symbols then letters as they grow — with difficulty that adapts to each person's own threshold.
Month-precise, age-normed scoring of reaction-time variability and the lapse tail into a single calibrated screening probability — with its uncertainty shown.
Effort and validity checks adapted from forensic neuropsychology. When the data can't be trusted, the score is suppressed — confidence at low cost, not a fraud filter.
A plain-language clinician summary and visit-over-visit tracking that separates real treatment response from practice effects and noise.
The youngest children in a class are diagnosed and medicated more than the oldest — for being younger, not for having ADHD. A tool only fixes that if its norms are precise enough to tell a 6.1-year-old from a 6.9-year-old.
A 6.1-year-old and a 6.9-year-old with identical reaction times receive different results — because more variability is normal at 6.1. That difference is the whole point.
No blood test, gene panel, or EEG has ever delivered a standalone ADHD diagnosis — the biology is too heterogeneous and the markers too non-specific. ADHD is diagnosed clinically, across settings, with history and impairment. Tabula Attentiva gives a clinician better objective data and a clearer triage decision. It does not replace their judgment, and it never claims to.
Runs in-office, bundles with complementary tasks in one sitting, and produces a clinician-ready report and a longitudinal trajectory. We're partnering with pilot sites and clinical advisors ahead of formal validation. If that's you, get in touch.
No. It's a screening and decision-support aid. ADHD is diagnosed clinically under DSM-5-TR using cross-setting history, functional impairment, and rule-out of other causes. The tool gives objective data and a triage signal; it never replaces clinical judgment.
Objective attention markers from reaction-time tasks — chiefly reaction-time variability and the ex-Gaussian lapse tail (tau), the most replicated objective ADHD signals — plus built-in performance- and symptom-validity checks, all normed to the person's exact age.
No validated blood test, gene panel, or EEG gives a standalone ADHD diagnosis. The disorder is biologically heterogeneous and candidate markers are non-specific — which is exactly why an objective behavioral measure is the practical adjunct.
The youngest children in a class are diagnosed with ADHD more than the oldest — an artifact of teacher referral, not biology. Every marker is normed to a child's exact age (month-precise), so normal immaturity isn't read as a deficit, and the report flags the child's relative-age position.
No. Stimulants improve attention in people without ADHD too, so a positive response isn't diagnostic. The developmental-history scoring deliberately gives it zero weight.
Run the attention task, watch the reaction-time distribution build, and see how the validity and relative-age layers change the read — right in your browser.
