First-line treatments
Drug therapy and clinical monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Intravenous Immunoglobulin (IVIG)
IVIG is the primary first-line immunotherapy that modulates immune system function and reduces antibody-mediated nerve damage. Treatment involves slow intravenous infusion under medical supervision.
Plasma Exchange (Plasmapheresis)
Procedure to remove pathogenic antibodies from the bloodstream and replace plasma with albumin or saline solution, reducing autoimmune attack on nerves.
Additional treatment options
Corticosteroid Therapy
High-dose corticosteroids may be used as adjunctive or alternative immunotherapy to reduce inflammation and suppress autoimmune activity.
medicationNeurorehabilitation Program
Comprehensive physical and occupational therapy to maintain muscle strength, improve balance, and restore functional mobility during recovery phase.
