Quick answer. Parkinson’s disease is a progressive brain condition caused by the loss of dopamine-producing nerve cells. Its main motor symptoms are a resting tremor (often a ‘pill-rolling’ shake of one hand), slowness of movement (bradykinesia), muscle stiffness, and later, balance and walking problems. Non-motor symptoms such as constipation, loss of smell, sleep and mood changes are common too. There is no cure, but it is very treatable: levodopa and other medications replace dopamine and can control symptoms well for years, and deep brain stimulation (DBS) helps selected patients. In Singapore, diagnosis is clinical, made by a neurologist. With treatment and support from groups like Parkinson Society Singapore, many people stay active a long time.

Parkinson’s disease is a long-term neurological condition that develops when the brain gradually loses nerve cells that produce dopamine, a chemical messenger that helps control movement. It usually appears after age 60 but can occur earlier (young-onset Parkinson’s). It is progressive – symptoms slowly worsen over years – but it is also one of the most treatable neurological conditions, and many people live well for a long time.
This guide explains the symptoms to look out for, how Parkinson’s is diagnosed and treated in Singapore, and how to live well with it. It is general information and not a substitute for assessment by a neurologist.
At a glance
| Feature | What it looks like | Notes |
|---|---|---|
| Resting tremor | Shaking of a hand, often 'pill-rolling', when the limb is at rest; eases with movement | Often the first sign; usually starts on one side |
| Bradykinesia (slowness) | Movements become slow and small – smaller handwriting, reduced arm swing, shuffling steps | A core feature required for diagnosis |
| Rigidity (stiffness) | Stiff, tight muscles; aching shoulders or limbs | Can be mistaken for arthritis early on |
| Postural / balance problems | Unsteadiness, stooped posture, tendency to fall | Tends to appear in later stages |
| Non-motor symptoms | Constipation, reduced sense of smell, sleep problems, low mood, soft voice | May appear years before tremor |
Recognising the symptoms
Parkinson’s symptoms usually begin gradually and often on one side of the body. The classic motor symptoms are:
- Tremor: a rhythmic shaking, often of a hand or fingers, that is most noticeable at rest and lessens with purposeful movement.
- Bradykinesia (slowness of movement): everyday actions take longer; handwriting may shrink, facial expression may reduce, and walking becomes a shuffle with reduced arm swing.
- Rigidity: stiff, tense muscles that can cause aching and reduced range of movement.
- Postural instability: problems with balance and posture, usually in later stages, increasing fall risk.
Non-motor symptoms are very common and can appear early – including constipation, loss of sense of smell, acting out dreams or other sleep disturbance, low mood or anxiety, and a softer voice. Not everyone has tremor; some people present mainly with stiffness and slowness.
Progressive but manageable – an honest picture
It is important to be honest: Parkinson’s disease is progressive, meaning symptoms gradually advance over time, and there is currently no cure. However, it is not a condition you can do nothing about. Effective medications, allied therapies and (for selected people) surgery can control symptoms well, often for many years.
The rate of progression varies a lot from person to person, and Parkinson’s itself is not usually directly life-threatening. With good treatment and support, most people remain active and independent for a long time, and continue working, exercising and enjoying life. The goal of care is to keep you functioning well and maintain quality of life at every stage.
How Parkinson's is diagnosed in Singapore
There is no single blood test or scan that confirms Parkinson’s disease. The diagnosis is clinical – made by a neurologist based on your symptoms, medical history and a neurological examination that looks for slowness, rigidity and tremor.
- Scans such as MRI or a DaT scan may be used to help rule out other conditions that can mimic Parkinson’s, but they are not always needed.
- A clear improvement in symptoms when starting dopamine-based medication also supports the diagnosis.
Because several other conditions (such as essential tremor or drug-induced parkinsonism) can look similar, assessment by a neurologist or movement-disorder specialist is important to get the diagnosis right.
Treatment: medication, DBS and therapies
Treatment is tailored to your symptoms, age and stage. Main options include:
- Levodopa: the most effective medication, it is converted to dopamine in the brain and remains the cornerstone of treatment, often combined with carbidopa or benserazide. It can control symptoms very well, especially in earlier years.
- Dopamine agonists: mimic dopamine and may be used, particularly in younger patients.
- MAO-B and COMT inhibitors: help dopamine last longer in the brain.
- Other medications: such as amantadine and anticholinergics for specific symptoms.
As the disease advances, some people develop response fluctuations or involuntary movements (dyskinesia). Deep brain stimulation (DBS) – implanting electrodes in specific brain areas – can significantly improve symptoms and reduce medication-related fluctuations in carefully selected patients, and is performed in Singapore. Physiotherapy, occupational therapy and speech therapy are valuable at every stage to maintain mobility, function and communication. Regular exercise is strongly encouraged.
Living well and finding support in Singapore
Day-to-day strategies make a real difference:
- Keep active. Regular exercise – walking, stretching, tai chi, dance or balance work – helps mobility, mood and balance.
- Take medication on time. Parkinson’s medications work best when taken at consistent times; ask your team about timing around meals.
- Prevent falls. Remove trip hazards, use good lighting and grab bars, and review balance with a physiotherapist.
- Address non-motor symptoms. Constipation, sleep, mood and blood pressure can all be managed – raise them with your doctor.
Parkinson Society Singapore (PSS) offers support groups, caregiver workshops, exercise programmes and resources, including a circle for younger patients. Caregivers should also seek support and respite. Care is available through public hospitals’ neurology and movement-disorder services, with subsidies and financial assistance schemes for eligible patients.
