If you google the two conditions together you will see an interesting trend of articles and studies. Those studies are mostly about parents with MS having children with autism. This suggests a link they are currently studying, but have no distinct answers on yet.
My own conditions have been getting progressively worse over the years. I fatigue faster, lose coordination a lot, have trouble forming words and speaking, and I have increasing random tremors that are more like lightning jolts. Autism isn't particularly know for being a progressive condition. So what's the difference?
I found this information about the nerve effects of the two conditions:
MS is a degeneration of protective layers around nerve endings, eventually leading to progressive nerve damage.
Autism is a developmental disorder of the nerves themselves.
So, from those two descriptions, it's entirely possible to start out with Aspergers or some other form of autism and develop MS later on. Like Autism, MS can have profusely different effects on each person. It's another broad spectrum with a hundred million combinations.
In any case, I am sitting on a possible MS diagnosis. That's why I'm researching it to learn what the possibilities are and what I can do about it. No, I can't stop it from happening, but knowledge is power. If I have to live with this condition, I want to know as much about it as possible. I see the neurologist this month.
I find the connection thought provoking to say the least. There are connections being drawn to Alzheimer's and Parkinson's as well. Is there a common root to link them all? If so, how do you find it? It must be like finding a specific needle in a stack of needles as big as the proverbial haystack.
