galop syndrome

The only treatment that is the same is intravenous immunoglobulin. They use a chemotherapy drug cyclophosphamide to suppress the immune system which is in adifferent drug family that is used in CIDP
Corticosteroids which are used in CIDP are unlikely to be of benefit people with Gallop syndrome.
So it’s a yes no answer.

Gait disorder

Polyneuropathy

GALOP syndrome is considered a variant of the antisulfatide syndrome. Antisulfatide antibodies are associated with several subtypes of peripheral neuropathy. Predominantly sensory or sensorimotor axonal neuropathies are most common in this series, with the sensory component either small fiber or mixed fiber type. More info here:

According to what I’ve read and what Ausvoltz has said above – IVIg, SCIg, or cyclophosphamide, may produce improvement in weakness, sensory loss or gait disability. Corticosteroids (Prednisone, etc.) are doubtful to be of any aid, even when neuropathy is demyelinating.
