Key facts
Parkinson’s at a glance.
The essentials, in plain English - what it is, how common it is, how it is diagnosed, and how it is treated in the UK today.
-
What it is
A progressive neurodegenerative condition caused by loss of dopaminergic neurons in the substantia nigra.
-
How common
Around 1 in 500 people in the UK - roughly 145,000 people living with Parkinson’s today.
-
Diagnosis
Clinical, supported by a DaTscan when the picture is unclear. There is no single blood test.
-
Non-motor first
Constipation, loss of smell, REM sleep behaviour disorder and mood change often precede tremor by years.
-
Main treatment
Levodopa remains the most effective symptomatic therapy, complemented by agonists and MAO-B inhibitors.
-
Advanced options
Deep brain stimulation, apomorphine infusion and Duodopa intestinal gel help select advanced patients.
Why this guide matters
Small choices, years of independence.
Parkinson’s care has changed dramatically. The three points below shape everything else on this page.
-
Early diagnosis is worth it
A clear diagnosis unlocks the multidisciplinary team - nurses, physios, OTs - who make the biggest long-term difference.
-
Levodopa still wins
It remains the most effective symptomatic therapy. Modern add-ons smooth out its effect as the years pass.
-
Advanced therapies exist
Deep brain stimulation, apomorphine and Duodopa give real options when tablets alone are not enough.
How the diagnosis is made
From first symptoms to a clear plan.
The steps a UK GP and neurologist will normally follow, in order - so you know what to expect and why.
Phase 1 · Recognising
History, examination and the clinical core
Phase 2 · Confirming
Rule out drug causes and atypical parkinsonism
Phase 3 · Managing
Specialist and team-based long-term care
- 01
Recognising
Symptom and family history
Slowness, tremor, changes in handwriting, sleep or smell - and any relatives with Parkinson’s.
- 02
Recognising
Neurological examination
Bradykinesia plus rigidity, tremor or postural instability - the clinical core of the diagnosis.
- 03
Confirming
Rule out drug-induced causes
Antipsychotics, metoclopramide and prochlorperazine can all mimic Parkinson’s and must be excluded first.
- 04
Confirming
DaTscan if unclear
A nuclear-medicine scan of dopamine transporters, used when the clinical diagnosis is uncertain.
- 05
Confirming
MRI brain
Not to diagnose Parkinson’s itself, but to exclude atypical parkinsonism, vascular disease or hydrocephalus.
- 06
Managing
Neurology consultation
A movement-disorder specialist confirms the diagnosis and starts treatment tailored to your stage.
- 07
Managing
Multidisciplinary team
A Parkinson’s nurse, physiotherapist, occupational therapist and SLT together shape long-term care.
Typical timeline: 2-4 months from GP referral to a settled specialist plan.
Symptoms
What Parkinson’s actually looks like.
A mix of motor and non-motor features. The non-motor picture often begins years before the tremor - and matters just as much day to day.
-
Resting tremor
A slow pill-rolling tremor of a hand at rest, easing on movement - often the first visible sign.
-
Bradykinesia
Slowness of movement - smaller handwriting, reduced arm swing, a shuffling gait.
-
Rigidity
Muscle stiffness, cogwheel resistance when a joint is moved, aching shoulders and neck.
-
Postural instability
A tendency to fall backward on gentle balance testing, developing later in the illness.
-
REM sleep behaviour disorder
Acting out dreams during sleep - often kicking or shouting - can precede motor symptoms by years.
-
Depression and apathy
Low mood, reduced drive and anxiety are common - and often respond well to treatment.
-
Autonomic symptoms
Constipation, low blood pressure on standing and urinary urgency - the non-motor picture.
-
Red flag: sudden severe symptoms
Sudden weakness, slurred speech or facial droop is a stroke until proven otherwise - call 999.
Treatment
How Parkinson’s is treated in the UK.
Medication is the backbone, with device-assisted therapies for advanced disease and therapy input throughout - what each option does, and when it fits.
-
Levodopa
Co-careldopa or co-beneldopa - the most effective symptomatic therapy, the backbone of treatment.
-
Dopamine agonists
Ropinirole or pramipexole - useful in younger patients, but watch for impulse-control side effects.
-
MAO-B inhibitors
Rasagiline or selegiline - a gentle first option, or added on to reduce end-of-dose wearing off.
-
COMT inhibitors
Entacapone - extends the duration of each levodopa dose when wearing off becomes a problem.
-
Apomorphine (infusion or pen)
A potent dopamine agonist given under the skin, used for sudden off periods in advanced disease.
-
Deep brain stimulation
Electrodes to the subthalamic nucleus or globus pallidus - transformative for selected advanced patients.
-
Duodopa intestinal gel
Levodopa delivered continuously via a small pump into the jejunum, smoothing out motor fluctuations.
-
Physiotherapy, SLT and OT
Movement, speech and daily-living therapy - as important as medication for staying independent.

Red flags
When Parkinson’s needs urgent review.
Most changes can wait for a routine appointment. These are the patterns that need same-day assessment - do not sit on them.
-
Sudden severe symptoms
Sudden weakness, slurred speech or facial droop points to stroke - call 999.
-
Rapid decline
Very fast progression over months suggests atypical parkinsonism (MSA, PSP, CBD) rather than Parkinson’s.
-
Dementia with Lewy bodies
Early visual hallucinations, fluctuating cognition and neuroleptic sensitivity - a related but distinct diagnosis.
-
Impulse-control disorders
Gambling, hypersexuality or compulsive shopping on dopamine agonists - stop the drug and tell the team.
-
Neuroleptic malignant syndrome
Fever, rigidity and confusion after abrupt withdrawal of dopaminergic therapy - a medical emergency.
-
Deep-brain-stimulation infection
Redness, discharge or fever around the DBS site or chest generator - urgent neurosurgical review.
-
Aspiration risk from dysphagia
Coughing with meals or recurrent chest infections - request an SLT swallow assessment.
-
Falls with fractures
Repeated falls and injuries need bone health review, physiotherapy and home-safety assessment.
-
Palliative-stage crisis planning
Advance care planning avoids crisis admissions in late disease - discuss early with the specialist team.
Living with it
A long-term condition, but a very manageable one.
Four things that make the biggest difference year on year - exercise, timing, team and planning ahead.
A quiet reminder
Consistency beats intensity, every time.
Small, steady changes - kept up for months - do more than a heroic week that does not last.
- 01 Movement
Exercise is medicine
Regular aerobic and resistance exercise slows functional decline more than any lifestyle change we know of.
- 02 Timing
Take medication on time, every time
Even a 30-minute delay can bring on wearing-off symptoms - set alarms and carry a pill box.
- 03 Team
Use the multidisciplinary team
Parkinson’s nurses, physios, OTs and SLTs make a bigger difference over years than any single specialist.
- 04 Planning
Plan ahead for advanced disease
Talk about DBS, Duodopa or advance care planning while decisions can be made calmly, not in a crisis.
Frequently asked
Everything we get asked about Parkinson’s.
Quick answers on diagnosis, levodopa, DBS, non-motor symptoms, scans and impulse-control side effects.
-
How is Parkinson’s diagnosed?
Clinically - by a neurologist finding bradykinesia together with rigidity, tremor or postural instability, after excluding drug-induced causes. A DaTscan is used when the picture is unclear, and MRI helps rule out mimics.
-
Is levodopa still the best treatment?
Yes. Levodopa (co-careldopa or co-beneldopa) remains the most effective symptomatic therapy for motor symptoms. Dopamine agonists, MAO-B inhibitors and COMT inhibitors are added to smooth out its effect over time.
-
Who is suitable for deep brain stimulation?
Selected patients with disabling motor fluctuations or dyskinesia who still respond to levodopa, without significant cognitive impairment. A specialist DBS assessment is required.
-
What are the non-motor symptoms?
Constipation, loss of smell, REM sleep behaviour disorder, depression, anxiety, low blood pressure on standing and urinary urgency - many of these begin years before tremor or slowness.
-
Will I need a scan?
Often. MRI of the brain is used to exclude atypical parkinsonism and vascular disease. A DaTscan is used when the clinical diagnosis is uncertain, not routinely.
-
What about impulse-control side effects?
Dopamine agonists (ropinirole, pramipexole) can cause gambling, hypersexuality or compulsive shopping in a minority of patients. If this happens, tell your team immediately - the drug can be reduced or stopped.
