Remember, all the "SP" people were once "RR" people. I used to think it too if I didn't say it: "I don't have anything permanent. Those other people aren't me."
When you are still mobile and independent, it is not something you worry about, not being those things. Unless you are very special (like the man who helped his father, after a stroke, learn again to climb mountains) you don't think it will ever happen to you. You are unlikely to even try help someone who "science" agrees is "beyond help".
By now it has happened to me. Yes, I have lost some of my nervous system.
I have experienced those times, when you are suddenly, and briefly, able to do those things that you thought you never would again, for a short time. I worked with one therapist who tried vainly to help me move my left leg. I saw the surprise on her face, the morning I could raise my knee to waist height. By the next day I couldn't anymore.
So I believe those pathways were not dead. More like the brains of the people in "Awakenings".
Even so, I believe over time, my brain reuses its "control circuits", if they are unused. Parts of the pathway are lost. More and more can be lost, through "use it or lose it". Same goes for my thigh muscle. That, I can see, is not being reused, except for its value as food.
My brain, though, has a massive amount of redundancy. So does my spine. Relearning is still possible until all peripheral nerves are gone.
I know in an injury, those peripheral axons get transected. It currently isn't possible to regrow them. I've never had that accident, though my friend has. I think even she, who is a "walking quad", might be helped by the CCSVI procedure. And we're both trying to keep muscles.
Please keep it to yourself, if you think I'm wasting my time.
It's my time, and I'll waste what I want. :^)
