2

First-line immunotherapy

Corticosteroid therapy serves as primary immunosuppressive treatment to reduce antibody-mediated synaptic inflammation. Treatment is initiated based on symptom severity and antibody persistence.

3

Neurological and cognitive monitoring

Regular neurological examinations and cognitive assessments to track disease course and treatment response. Serial imaging may be considered if clinical progression warrants further investigation.

Additional treatment options

Intravenous immunoglobulin

IVIG provides immunomodulation by blocking antibody binding and modulating Fc receptor function. May be particularly beneficial in synaptic receptor antibody-mediated conditions affecting cerebellar function.

medication

Second-line immunosuppressants

Azathioprine, mycophenolate, or methotrexate may be added for steroid-sparing effect or when first-line therapy is insufficient. These agents require time to achieve therapeutic effect.
