LimbusHealth Assess · In development

Adult ADHD assessment software for patients and doctors.

Limbus prepares a draft assessment report for doctor review.

Before the appointment, the patient completes a guided history, screening questionnaires, and an adaptive text interview. Each finding in the draft links back to the answer it came from. The doctor reviews and corrects the report, speaks with the patient, and decides whether ADHD is the right diagnosis.

LimbusHealth Assess · Method

What the patient does. What Limbus prepares. What the doctor decides.

Limbus collects and organizes the pre-appointment information into a draft assessment report. It does not replace the doctor’s own interview, judgment, or diagnosis.

Join the Assess waitlist

Patient intake

History and concerns, completed before the visit.

The patient records current concerns, day-to-day impact, childhood history, health history, and context in a guided intake they can complete before the appointment.

Illustrative pathway view · stage 1 of 3 · not product output

Screening questionnaires

ADHD symptoms and related concerns, in one place.

The patient completes structured screening questions. Scores help guide what to ask next; they do not become a diagnosis on their own.

Illustrative pathway view · stage 2 of 3 · not product output

Adaptive text interview

Follow-up questions respond to the patient’s answers.

Assess asks about ADHD criteria, day-to-day impairment, childhood onset, possible alternative explanations, and safety concerns. Each finding stays linked to the answer it came from.

Doctor review

One draft to review, not a diagnosis to accept.

The doctor receives the source-linked draft, checks each finding, speaks with the patient, corrects what is wrong or incomplete, and decides whether ADHD is the right diagnosis. Nothing is finalized until the doctor reviews and signs it.

One assessment · two connected experiences

The patient and doctor use different sides of the same assessment.

Each role keeps its own responsibilities: what you bring to the assessment, what you get back, and what stays yours to decide.

Patient perspective

Complete the history before the appointment, one clear step at a time.

Work through each step at your own pace before the appointment. Nothing asks you to interpret the information or diagnose yourself.

You provide: History, concerns, context
You receive: A clear place in a doctor-led assessment
The doctor owns: Conversation, interpretation, decision

Join the Assess waitlist

Doctor perspective

Open one draft with the evidence beside each finding.

Every finding sits beside the answer it came from, with missing information, contradictions, and possible alternatives flagged for your review.

You receive: A structured, traceable draft
You inspect: Evidence, gaps, alternatives
You own: Clinical review and sign-off

Clinical organization perspective

A defined assessment process with a doctor visibly responsible at the end.

Assess is being developed around structured patient input, traceable records, doctor review, and a clear separation between software output and the final clinical decision.

The workflow keeps: Roles and handoffs explicit
The record keeps: Sources and uncertainty visible
The organization keeps: Its clinical governance authority

A draft should look like a draft.

This fictional example is not output from the Limbus system. It shows the intended accountability boundary: the software organizes a draft; a doctor questions it, corrects it, and decides.

Draft impression: adult ADHD, combined presentation(confidence: high).

Late task completion attributed to inattention.

Working conclusion: ADHD is the leading explanation.

Clinical leadership

Clinical judgment shaped the product from the start.

Limbus is built around the realities of assessment and treatment: limited appointment time, overlapping symptoms, incomplete records, and decisions that still require accountable human judgment.

Clinical direction

Dr. Marie Claire Bourque

MD, FRCPC · Psychiatrist

Royal College–certified and practicing in British Columbia and Ontario, with experience across emergency, inpatient, and outpatient care.

What clinical leadership changes

Evidence: Findings should remain traceable to what the patient actually provided.
Uncertainty: Missing information, contradictions, and competing explanations should stay visible.
Responsibility: By design, software should remain subordinate to the treating doctor’s judgment, review, correction, and decision.

Questions worth answering directly.

For patients & doctors

What does LimbusHealth Assess actually do?

Assess is adult ADHD assessment software for patients and doctors. Before the appointment, the patient completes a guided history, screening questionnaires, and an adaptive text interview. Limbus organizes the answers into a source-linked draft assessment report. The doctor reviews and corrects it, speaks with the patient, and decides whether ADHD is the right diagnosis.

Does LimbusHealth Assess make diagnoses on its own?

No. Limbus prepares a draft for review; it does not give the patient a diagnosis or replace the doctor’s assessment. The doctor checks the source evidence, corrects the draft, resolves uncertainty, and makes the clinical decision.

Is Limbus authorized for clinical use?

Not yet. LimbusHealth Assess is software as a medical device in development for adult ADHD assessment. Its Canadian classification and authorization pathway remains unresolved, and it is not authorized for clinical use (as of August 2026).
