Parkinson's Disease
Parkinson's disease is a progressive brain condition where cells that make dopamine are lost, leading to tremor, stiffness and slow movement. Symptoms develop gradually over years.

- Older age
- Genetic factors in some families
- Possible environmental exposures
- More common in men
Common symptoms
- Tremor, often in a hand at rest
- Slowness of movement
- Muscle stiffness
- Balance problems and shuffling walk
- Small, cramped handwriting
- Soft or slurred speech
- Constipation
Tests & diagnosis
Treatment & management
- Medicines that boost or mimic dopamine to ease symptoms
- Physiotherapy for movement, balance and posture
- Speech and occupational therapy
- Regular exercise to maintain mobility
- Advanced options such as deep brain stimulation in selected cases
When to see a doctor urgently
- A new tremor, stiffness or slowness of movement

Frequently asked questions
Is Parkinson's disease fatal?
Parkinson's itself is not usually a direct cause of death, and treatment can control symptoms for many years. It is a long-term condition that needs ongoing care as it progresses.
Does everyone with a tremor have Parkinson’s?
No. Many tremors are due to other causes, such as essential tremor or anxiety. A Parkinson tremor is typically most noticeable at rest. A doctor can tell them apart.
