Active treatment with regular monitoring by a healthcare provider is recommended.
Plasmapheresis
Direct removal of pathogenic anti-GM2 antibodies through centrifugal or filtration-based plasma separation techniques.
Additional treatment options
Corticosteroid Pulse Therapy
High-dose methylprednisolone or prednisone suppresses inflammatory demyelination and antibody-mediated nerve injury.
medicationChronic Pain Management Support
Integrated psychological approaches including CBT and pain coping strategies address the significant neuropathic pain component common in anti-GM2 neuropathy.
psychologicalComprehensive Neurological Assessment
