My husband was diagnosed with Non Hodgkin's Burketts Like Sept. 2008. During treatment he woke up and felt like the world was spinning. He had loss of balance and he lost his ability to speak. We were told that this was side effect of ARA C (Cytarabine)and that all would go away. It is now 1 year later and things have improved somewhat, but he can only walk with a walker and still has great difficulty speaking. He has had speech and physical therapy. Docs just look at us now and have no answers. Has this happened to anyone else out there? Scans are negative but life is not so good.
