Many MRIs have not determined the cause. Mary spent two months in a rehab, and now is home alone. She has a few residual effects of the illness, mainly memory loss and dizziness. Our main problem is that even though she is doing well considering her condition, she wants to dwell on the illness, causes and effects, and would very much like to have someone to talk to about encephalitis. We live in the Boston area and if anyone knows about a support group, I'd appreciate the info. Her neurologist did not have any information for her.
