I don't believe there's a connection (i.e, causative) but it's fairly well known that advanced lyme causes permanent neurological symptoms. Two different disease processes....same end result.

I had lyme disease in 1989 (lived in CT, so it's a foregone conclusion you'll get it!) It was caught quickly. I estimate 4 weeks after tick exposure. I had horrible pain in joints and flu-like symptoms. I was treated with ABX for a prolonged period and never had any issues afterwards.

in 2001 I was dx'd with MS. I have a mom with MS, had a hep B shot several months prior to dx, and as an environmental consultant, I've had lots of exposure to chemicals. So, I have plenty of risk factors.
