Guillain-Barré Syndrome is an acute, immune-mediated polyneuropathy characterized by rapid-onset muscle weakness, paresthesia, autonomic dysfunction, and potential respiratory failure. It commonly follows infections such as Campylobacter jejuni, cytomegalovirus, Epstein-Barr virus, influenza, and-in rare cases-vaccination or viral outbreaks. GBS requires immediate medical intervention, often in high-dependency or ICU settings.

Key Market Highlights
• 2024 Market Size: USD 684 million
• 2034 Forecast: USD 1.39 billion
• CAGR (2025-2034): 7.4%
• Largest Treatment Segment: IVIG therapy
• Fastest-Growing Segment: Plasmapheresis and complement-targeting biologics

Epidemiology & Clinical Insights
1. Incidence
• GBS affects 1-2 per 100,000 people annually, making it one of the most common causes of acute flaccid paralysis worldwide.
• Incidence increases with age and is slightly more common in males.
2. Subtypes of GBS
• AIDP (Acute Inflammatory Demyelinating Polyneuropathy) - most common in Europe & North America
• AMAN (Acute Motor Axonal Neuropathy) - higher prevalence in Asia & Latin America
• AMSAN (Acute Motor and Sensory Axonal Neuropathy)
• Miller Fisher Syndrome - rare variant with ophthalmoplegia
3. Clinical Burden
Patients may experience:
• Progressive paralysis within days
• Respiratory muscle failure
• Autonomic instability
• Pain and sensory abnormalities
4. Standard Diagnostics
• Nerve conduction studies
• Lumbar puncture showing albuminocytologic dissociation
• MRI ruling out differential diagnoses

Market Growth Drivers
1. High Dependence on IVIG Therapy
IVIG remains the gold-standard treatment and represents a major cost driver in GBS management.
2. Advances in Plasmapheresis (Plasma Exchange)
Improved apheresis technology increases adoption in severe and rapidly progressive cases.
3. Expanding Awareness & Diagnostic Rates
Neurologists increasingly screen for GBS during infectious outbreaks.
4. Growing Incidence of Triggering Infections
Campylobacter outbreaks, Zika virus, influenza, and post-COVID sequelae have increased demand for GBS care.
5. Rising Investments in Neuromuscular Disorder Care
Hospitals expanding neuro-ICU capacity and infusion services contribute to market growth.

Market Restraints
• High cost of IVIG and limited supply
• Need for ICU care in severe cases
• Long recovery period affecting long-term outcomes
• Lack of widely approved targeted pharmacological treatments
• Variable access to plasmapheresis equipment in low-income countries

Market Opportunities
1. Development of Targeted Biologics
Emerging therapies target:
• Complement pathway (e.g., C5 inhibitors)
• FcRn inhibitors
• Autoimmune modulation pathways
2. Growth in Home-Based Infusion Services
Stable patients may receive follow-up IVIG doses in outpatient or home settings.
3. Predictive Biomarkers & Precision Diagnostics
Biomarkers identifying high-risk patients could enable early intervention.
4. Improved Rehabilitation Technologies
Neuro-rehabilitation solutions support long-term recovery.
5. Expansion of Apheresis Centers in Asia & Latin America
These regions have high incidence of axonal subtypes.

Segmentation Overview
By Treatment
• Intravenous immunoglobulin (IVIG)
• Plasmapheresis (plasma exchange)
• Complement inhibitors (pipeline)
• FcRn inhibitors (pipeline)
• Supportive therapy (ventilation, physiotherapy, autonomic management)

By Subtype
• AIDP
• AMAN
• AMSAN
• Miller Fisher variant

By End User
• Hospitals
• Critical care units
• Neurology centers
• Infusion clinics
