Parkinson's disease management selector
Pick the age band, cognition, predominant symptom, functional impact and disease stage to get ranked management suggestions — from initial oral therapy through advanced / device-aided options — across the Health Canada-approved formulary, with the guideline reasoning and references behind each.

Motor complications & cautions
Wearing-off and dyskinesia steer the adjunct choice; dementia, psychosis, ICD risk, sleepiness and orthostatic hypotension down-rank or route out dopamine agonists (and anticholinergics).
Safety & guideline notes
- • Per the Canadian Guideline for Parkinson Disease, 2nd ed. (2019): levodopa is the most effective drug for motor symptoms and is first-line when they affect quality of life; dopamine agonists and MAO-B inhibitors are options for milder / earlier disease, used cautiously in older or cognitively impaired patients.
- • This tool assumes a confirmed diagnosis of idiopathic Parkinson's disease. If the diagnosis is uncertain, or atypical / secondary parkinsonism is suspected (early falls, prominent early autonomic failure, poor levodopa response, rapid progression), refer to a movement-disorder specialist before treatment.
- • Coverage: most oral PD medications are covered under provincial formularies (e.g. ODB, often as Limited Use); device-aided therapies (DBS, Duodopa, Vyalev) require special authorization and specialist initiation — confirm against the live provincial formulary.
Select the clinical profile to begin.
e.g. Age > 70 + Significant impact + Early, or Advanced + Wearing-off to see the device-aided pathway.
