Parkinson's Disease and Movement Disorders
Parkinson's disease is more than tremor. It is a progressive neurological disorder that can affect movement speed, stiffness, walking and balance, and can also involve sleep, mood, bowel function, smell and cognition. Assessment aims to understand the whole pattern and build a plan around the individual patient.
The core idea
Parkinson's disease is a progressive neurological disorder associated with loss of dopamine-producing neurons in a brain region called the substantia nigra. This contributes to slowness of movement, stiffness and tremor, while non-motor symptoms can include sleep problems, constipation, mood changes, reduced sense of smell and cognitive changes.
The full pattern matters more than one symptom
Symptoms vary from one person to another and usually develop gradually. Assessment focuses on the pattern, timing and effect on daily life.
What does the neurologist look for?
The neurological examination looks at the speed and coordination of movement, hand and finger tasks, facial expression, voice, standing from a chair, walking, turning, arm swing and balance. These details are more useful than relying on a single image or blood test.
Diagnosis
There is no single test that confirms Parkinson's disease in every patient. Diagnosis is clinical and starts with the history and examination. Bradykinesia is a core feature of parkinsonism, then findings such as resting tremor, rigidity and balance problems are assessed. Other tests are used when they can answer a specific question or help exclude another cause.
When did symptoms start? Did they begin on one side? Are there medications or other conditions that could explain them?
Assessment of bradykinesia, rigidity, tremor, walking, balance and other neurological functions.
Laboratory tests or imaging may be requested if features are atypical or another diagnosis needs to be excluded.
The evolution of symptoms and response to treatment can provide additional diagnostic information.
Treatment plan
Treatment focuses on managing symptoms, maintaining mobility and independence, and addressing non-motor symptoms. The plan changes over time according to the patient's needs and response.
Levodopa and other medicines may be used depending on symptoms, age, health and treatment goals, with timing and doses adjusted according to response.
Regular physical activity is an important part of supporting balance, flexibility, fitness and the ability to perform daily activities.
Physical therapy, occupational therapy, speech therapy and swallowing assessment may be included when appropriate.
Deep brain stimulation (DBS) and other advanced treatments can be considered for selected patients after specialist assessment.
Rehabilitation and movement
Rehabilitation can support walking, balance, flexibility and strength, reduce fall risk and teach practical movement strategies at home and outdoors. Occupational therapy can help adapt daily activities, while speech and swallowing therapy can support communication and eating when needed.
Patient and family support
It is useful for the medical team to know how symptoms affect sleep, eating, constipation, mood, falls, speech, swallowing and daily activities. A family member can sometimes provide important observations during follow-up.
When do they worsen, and how do they relate to medication timing, sleep and meals?
Repeated falls or swallowing difficulty should be discussed early.
Anxiety, hallucinations or cognitive change are clinically important symptoms.
“In Parkinson's disease, the diagnosis name is only the beginning. What matters is understanding how movement, sleep, mood and daily function are affected, then building a plan that can change over time.”

Specialist assessment connects symptoms with the neurological examination, medication and associated conditions, then identifies what needs medication, rehabilitation, follow-up or additional testing.
Frequently Asked Questions
No. Tremor has many possible causes, and some people with Parkinson's do not have tremor as their most obvious symptom. Diagnosis depends on the overall symptom pattern and neurological examination.
There is no single test that confirms Parkinson's disease in every case. Diagnosis is mainly clinical. Imaging or laboratory tests may be used when needed to rule out other causes or answer a specific diagnostic question.
There is currently no cure that eliminates Parkinson's disease, but medication, exercise, rehabilitation and selected advanced treatments can help manage symptoms and support quality of life.
Yes. Appropriate physical activity and exercise can support mobility, balance, flexibility and mood. The programme should match the patient's ability, symptoms and fall risk.
Consider specialist review when there is a combination of slowed movement, stiffness, tremor, gait or balance change, or when the diagnosis is unclear or symptoms are not adequately controlled with the current plan.
Start with a structured neurological assessment that reviews symptoms, movement, medication and the most appropriate next step.
