In this clear, practical and highly relatable session, Dr Quentes De Vries — Geriatrician and General Physician at Beach Brain Clinic — breaks down exactly how Parkinson’s medications work, why symptoms fluctuate, and what patients can do to improve day-to-day management.
About This Video
Dr De Vries explains the essential medical concepts every person with Parkinson’s and every carer needs to understand:
- What Parkinson’s Actually Is
- Dopamine loss and how symptoms progress over decades
- Motor vs non-motor symptoms
- Early non-motor signs (loss of smell, constipation, sleep disturbance)
- Why diagnosis is clinical — not based on a single test
- Risk Factors & Protective Factors
- Pesticides, rural exposure, golf course chemicals, heavy metals, head injury
- Genetics, ageing, sex differences
- Caffeine, exercise and Mediterranean diet as possible protective factors
- How Parkinson’s Medications Work
He explains each drug group in simple language:- Levodopa (Madopar, Sinemet, Kinson)
- Dopamine agonists (patches and tablets)
- MAO-B inhibitors
- COMT inhibitors
Including:
Protein timing and levodopa absorption
Nausea, blood pressure drops, confusion, diarrhoea
Impulse control disorders (gambling, overspending, hypersexuality)
- Motor Fluctuations Explained
A highly practical section covering:- “Wearing off”
- “Delayed on”
- “No on” episodes
- Dyskinesia (too much movement)
- Why some people feel a missed dose immediately while others don’t
- Dopamine “reserve capacity” and why it shrinks over time

- Which patients benefit most and why patient selection matters
This session is direct, realistic and packed with explanations that help families understand why symptoms change — and what can be done to manage them better day-to-day.
