What is the typical prognosis for Guillain-Barre syndrome according to studies?

• A. The majority of patients will experience significant residual deficits
• B. The majority of patients will experience a full recovery
• C. The majority of patients will not experience any functional return
• D. The majority of patients will experience lethal complications

Answer: (B)

Guillain-Barré syndrome generally has a favorable outcome. In most patients, function returns fully or almost fully over weeks to months with appropriate supportive care and treatments such as IVIG or plasmapheresis. A minority may have lingering weakness or sensory changes, and mortality or severe complications are relatively rare with modern management. The studies thus support a prognosis where the majority experience full recovery, rather than persistent deficits or lethal outcomes.
