Parkinson's Treatment Pathway

See where clinical trials fit into your care journey

Early PD: Initial Treatment

When symptoms first require medication

Standard: Levodopa (co-beneldopa/co-careldopa), dopamine agonists (pramipexole, ropinirole), or MAO-B inhibitors (rasagiline, selegiline)

Motor Fluctuations

When levodopa wears off or causes unpredictable responses

Standard: COMT inhibitors (entacapone, opicapone), MAO-B inhibitors, or dopamine agonists added to levodopa

Advanced PD: Device-Assisted Therapies

For significant motor complications despite optimised oral therapy

Standard: Apomorphine infusion, levodopa-carbidopa intestinal gel (LCIG), or deep brain stimulation (DBS)

Disease-Modifying / Neuroprotection

Trials aiming to slow or stop disease progression — the Holy Grail of Parkinson's research

Standard: No approved disease-modifying treatment yet — trials are critical

About Parkinson's Disease

What is Parkinson's Disease?

A progressive neurological condition caused by the loss of dopamine-producing cells in the brain. Affects about 153,000 people in the UK. Symptoms include tremor, stiffness, slowness of movement, and balance problems.

Why Trials Matter

Current treatments manage symptoms but don't slow progression. Clinical trials are testing disease-modifying therapies, gene therapies, focused ultrasound, and novel drug delivery systems that could transform outcomes.

Non-Motor Symptoms

Parkinson's also causes sleep problems, depression, anxiety, constipation, and cognitive changes. Many trials now target these non-motor symptoms, which can be as debilitating as the movement problems.
