Specialised Clinical Guidance

Advanced Therapies for Parkinson's Disease

Advanced therapies may be considered when standard medication does not provide satisfactory symptom control. Treatment selection must be individualised and guided by an appropriately qualified movement disorder specialist.

MRgFUS (Ultrasound) Apomorphine Pump Duodopa / LCIG Therapy Comparison PCC Decision Support Discuss Options
SECTION 1 • INCISIONLESS PROCEDURES

MR-Guided Focused Ultrasound (MRgFUS)

MRgFUS is an incisionless procedure using focused ultrasound beams to create a small, precise lesion in a brain area involved in abnormal movement. MRI guides targeting and monitors treatment in real time. No electrode, wire or battery is implanted.

It is used mainly for selected people with disabling tremor. Approved indications and treated targets vary between countries and regulatory authorities.

Who May Benefit?

  • Severe tremor affecting daily activities
  • Inadequate response to medication
  • Symptoms predominantly affecting one side
  • Unsuitability for, or preference against, implanted hardware
  • Suitable MRI and skull-density assessment
  • Appropriate cognition and general medical fitness

Advantages

  • No surgical incision or implanted device
  • Potential reduction of tremor on the treated side
  • Neurological assessment during treatment
  • No repeated programming sessions
Real-time thermal MRI tracking ensures millimeter-precision target lesioning.

MRgFUS Limitations and Risks

Procedural Limitations:
  • The lesion is permanent, non-adjustable and cannot be switched off.
  • Treatment is commonly unilateral; availability and approvals evolve.
  • It may not improve fluctuations, dyskinesia, speech, balance, freezing or non-movement symptoms.
Reported Risks & Side Effects:

Risks include numbness, weakness, imbalance, speech or swallowing change, dizziness, nausea and persistent neurological effects.

SECTION 2 • SUBCUTANEOUS DOPAMINE AGONISTS

Apomorphine Pump Therapy

Apomorphine is a potent dopamine agonist. It is delivered under the skin as an intermittent rescue injection or continuous infusion through a portable pump.

Critical Pharmacological Clarification

Despite its name, it is not morphine, not an opioid and not a painkiller.

Apomorphine directly stimulates dopamine receptors in the brain to restore motor circuit signaling without addictive or narcotic properties.

Who May Benefit?

  • Levodopa-responsive Parkinson's with frequent or prolonged off periods
  • Unpredictable or delayed response to tablets
  • Dyskinesia limiting further oral medication adjustment
  • DBS or intestinal gel therapy unsuitable, unavailable or not preferred
  • Ability of the patient or caregiver to manage the pump after training

Potential Benefits

  • Reduced off time
  • More predictable movement control
  • Reduced need for repeated rescue doses
  • Possible simplification of oral medication
Avoids gastrointestinal absorption delays, providing direct subcutaneous bioavailability.

Limitations and Adverse Effects

  • Skin nodules, irritation or infection
  • Nausea, sleepiness, dizziness or low blood pressure
  • Confusion, hallucinations, dyskinesia or leg swelling
  • Impulse-control problems and rare blood abnormalities
  • Daily pump preparation, cannula care and site rotation
CLINICAL PROTOCOL

Monitoring Requirements

Treatment requires specialist initiation, dose adjustment, skin-care education, and appropriate clinical and laboratory monitoring.

Dedicated nurse support facilitates needle insertion and cannula rotation.
SECTION 3 • CONTINUOUS INTESTINAL INFUSION

Duodopa / Levodopa-Carbidopa Intestinal Gel (LCIG)

Duodopa, also called levodopa-carbidopa intestinal gel or LCIG, delivers levodopa and carbidopa directly into the small intestine through a portable pump. Continuous delivery can provide steadier levodopa levels than repeated tablets, particularly when stomach emptying or absorption is variable.

How It Is Delivered

1

Assessment & Trial

Specialist assessment and, in some centres, a temporary response trial using a temporary nasojejunal tube.

2

Endoscopic Placement

Endoscopic placement of a tube through the abdominal wall into the stomach (PEG procedure).

3

Intestinal Extension

Extension of the tube into the small intestine (jejunum) where dopamine is absorbed directly.

4

Continuous Infusion

A morning dose followed by continuous daytime infusion and prescribed extra doses for optimal control.

Who May Benefit?

  • Advanced levodopa-responsive Parkinson's
  • Severe motor fluctuations despite optimised tablets
  • Prolonged or unpredictable off periods
  • Troublesome dyskinesia or inconsistent absorption
  • DBS or apomorphine therapy unsuitable or not preferred
  • Patient and caregiver able to manage the pump and tube

Potential Benefits

  • Reduced off time and increased useful on time
  • Smoother symptom control
  • Fewer oral doses
  • Improved mobility and independence in selected people
Bypasses delayed gastric emptying to deliver continuous steady dopamine stimulation.

Limitations, Device Risks & Ongoing Care

Hardware & Gastrointestinal Considerations:
  • Tube blockage, displacement, disconnection or pump malfunction
  • Infection, irritation, leakage or abdominal pain
  • Gastrointestinal complications and need for tube replacement
Systemic & Nutritional Considerations:
  • Dyskinesia, hallucination, low blood pressure or sleepiness
  • Weight loss, peripheral neuropathy or vitamin deficiency in selected patients
Clinical Care Rule: Regular clinical review, nutritional assessment, tube care and caregiver training are important.

Clinical Selection Standard

"No single advanced therapy is best for everyone. Selection requires a movement disorder specialist and should consider expected benefit, risk, reversibility, practical burden, caregiver support, availability and cost."

Critical Patient Safety Alert

When Urgent Medical Attention Is Needed

While Parkinson's is generally a gradually progressive condition, certain acute symptoms demand immediate emergency evaluation.

Sudden weakness, facial deviation or speech difficulty

May signify an acute cerebrovascular event (stroke or TIA) requiring urgent brain imaging.

Sudden severe headache, loss of consciousness or seizure

Demands immediate neurological evaluation to exclude intracranial pressure or acute hemorrhage.

Repeated falls with injury

High risk of occult fractures, subdural hematoma, or acute mobility collapse requiring medical review.

Severe choking or breathing difficulty

Acute airway obstruction or aspiration risk requires emergency hospital resuscitation.

Sudden confusion, agitation or marked drowsiness

Acute delirium may indicate systemic infection (e.g. urinary or chest sepsis) or metabolic disturbance.

Persistent vomiting or inability to take Parkinson's medication

Missing dopaminergic medications can trigger severe rigidity, aspiration, or acute withdrawal crises.

High fever with severe stiffness or reduced responsiveness

May represent life-threatening Parkinsonism-hyperpyrexia syndrome or neuroleptic malignant-like syndrome.

Sudden major deterioration after medication changes

Acute adverse reactions, drug interactions, or dosage discrepancies requiring urgent medical adjustment.

Essential Clinical Guidance

"Do not assume every new symptom is Parkinson's. A sudden change may indicate stroke, infection, medication toxicity or another urgent condition. Seek immediate medical assessment."

Emergency Action: Do not wait for online messages, website responses, or standard clinic callbacks. Contact local emergency medical services immediately (e.g. dial 112 in India) or go to the nearest hospital emergency department.
