CIDP related swallowing problems - any treatment?

Hello,

My mom has CIDP. She has suffered a severe crisis about a year ago, when she was completely paralyzed and intubated.

Since then, through combined treatment of IVIG, cyclophosphamide, steroids and physical therapy she has seen great improvements in all systems except for her swallowing system. She is still being fed through a tube (peg).

Is anyone familiar with such a condition, and if so – do you know what treatments are available, and where?

Thank you
