Limbus Health is a clinician-led company developing clinical software for assessment and treatment. It was founded by Dr. Marie Claire Bourque, MD, FRCPC, a practicing psychiatrist in British Columbia and Ontario and the company’s sole developer.
LimbusHealth Assess is adult ADHD assessment software being developed for patients and doctors. Before the appointment, the patient completes a guided history, screening questionnaires, and an adaptive text interview. Limbus links each finding to the patient’s source answer, preserves contradictions and missing evidence, and prepares a draft assessment report. The doctor reviews and corrects the report, speaks with the patient, decides whether ADHD is the right diagnosis, and finalizes the clinical record.
LimbusHealth Treat is a separate product being developed for clinician-directed CBT with exposure and response prevention for adults with OCD. Its planned core is a deterministic treatment workflow; AI may assist communication or drafting but does not own diagnosis, treatment selection, progression, safety, or discharge decisions.
Both products are in development and neither is authorized for clinical use. For LimbusHealth Assess, the Canadian classification and authorization pathway remains unresolved as of August 2026. Limbus makes no claim of diagnostic accuracy, treatment effectiveness, or clinical validation. Limbus Health is based in British Columbia, Canada.
