Parkinson's disease
Parkinson's disease is a progressive movement disorder associated with degeneration of dopamine-producing brain cells, with both motor and nonmotor features.

Quick facts
- Category
- Neurological disorders
- What it is
- Parkinson's disease is a progressive movement disorder associated with degeneration of dopamine-producing brain cells, with both motor and nonmotor features.
- Typical presentation
- Slowness of movement, rigidity, resting tremor or balance difficulties may occur; sleep disturbance, constipation and mood changes can precede motor symptoms.
- Assessment
- Diagnosis is primarily clinical after neurological examination and review of medications or conditions that can mimic parkinsonism.
- Treatment approach
- Levodopa and other therapies address symptoms.
- Key safety concern
- Sudden new neurological deficits, repeated falls, severe swallowing difficulty or acute confusion require prompt evaluation and should not be assumed to be ordinary progression.

Overview
Parkinson's disease is a progressive movement disorder associated with degeneration of dopamine-producing brain cells, with both motor and nonmotor features.
Symptoms and presentation
Slowness of movement, rigidity, resting tremor or balance difficulties may occur; sleep disturbance, constipation and mood changes can precede motor symptoms.
CLINICAL FEATURES
Presentation and warning signs
The pattern varies and cannot replace an individual assessment.
- Slowness of movement
- rigidity
- resting tremor or balance difficulties may occur
- sleep disturbance
- Diagnosis is primarily clinical after neurological examination and review of medications or conditions that can mimic parkinsonism
- Interpret results with history and examination
- Sudden new neurological deficits, repeated falls, severe swallowing difficulty or acute confusion require prompt evaluation and should not be assumed to be ordinary progression.
Emergency symptoms and clinical severity should be assessed locally.
Clinical assessment and diagnosis
Diagnosis is primarily clinical after neurological examination and review of medications or conditions that can mimic parkinsonism.
ASSESSMENT
How the clinical assessment proceeds
Exact investigations depend on the clinical context.
Treatment and management
Levodopa and other therapies address symptoms. Exercise, physiotherapy and supportive care are important; selected advanced cases may be eligible for device-based treatment.
Treatment & care hub
Elements of care
Individual treatment is based on diagnosis, comorbidities and clinician assessment.
Understand the underlying condition
Diagnosis is primarily clinical after neurological examination and review of medications or conditions that can mimic parkinsonism.
Choose evidence-based management
Levodopa and other therapies address symptoms. Exercise, physiotherapy and supportive care are important; selected advanced cases may be eligible for device-based treatment.
Recognize warning signs
Sudden new neurological deficits, repeated falls, severe swallowing difficulty or acute confusion require prompt evaluation and should not be assumed to be ordinary progression.
Complications and when to seek help
Sudden new neurological deficits, repeated falls, severe swallowing difficulty or acute confusion require prompt evaluation and should not be assumed to be ordinary progression.
