Hi,
I just posted a response, but wanted to add something. My mother was initially diagnosed with pseudo bulbar palsy by a neuro,but after seeing an infectious disease dr., she was then diagnosed with Lyme via spinal tap (it did not come out in her blood), anyway, I know you have different circumstances, but I am happy to see that you are such a strong advocate for your husband. He is really lucky to have you. Please let me know how the appointment goes. best of luck, -v
