Unfortunately, I have no advice to give even though I have the diagnosis myself. I live in Europe, so have received treatment and diagnosis here.

I have had major problems with mobility and balance. I had major inflammations in both the brain and spinal cord. Also had problems with memory, vision problems, weakness and tremors in the arms and legs. After treatment (see previous post above) and physiotherapy, I have almost regained my normal functions. But I still suffering from fatigue though and continuing to slowly build up my physique.

I really hope you find a doctor who can help your father and that he receives treatment.
