I know, reposts are lazy, but in light of the recent injunction against NIH funding stem cell research, and the fact that, as a quadriplegic, I supposedly have a vested interest in the research, I thought I’d repost this entry I wrote last year.
—————
I know a couple of people who have spinal cord injuries who wholeheartedly believe in the potential of stem cells to magically cure them someday. One of these people has been injured since 1996 and has pretty much resigned himself to doing nothing other than watching TV and playing video games until the cure arrives.
Another is the son of a doctor whom I see. He was injured a week before I was when a wave crashed into him, driving his head into the sand, while at the beach. His injury is about an inch above mine and impairs him to a greater degree. He is active, but he and his father both believe there will be a cure someday.
Almost everyone who is newly injured insists that there will be someday. I don’t question the new guys, but I do question the lazy ones, specifically the former one I mentioned above. He happens to be kind of a jerk, so I don’t feel so bad when I ask him what he has read about stem cells. Many of those waiting haven’t read very much. They seem to take the promises at face value and block out anything to the contrary.
I should begin by saying that I do believe that stem cells could have a vital role in the treatment of diseases such as Parkinson’s and Alzheimer’s. But I can’t bring myself to believe they can repair a severed spinal cord.
The spinal cord is very complex, like a twisted bundle of fiber-optic cables. If you sever through that bundle, you’re going to have a mess of disconnections. If you’ve compressed several inches of your spine, that would be the equivalent of removing an inch or two out of that bundle. I just don’t believe that stem cells could reconnect things without running the risk of misconnecting and possibly leaving someone with greater disability or terrible nerve pain. Now that’s just my opinion.
What is actually proven in the laboratory with mice and dogs is that stem cells seem to provide a miraculous recovery in the days and weeks that follow an injury. After 13 months post injury, they’ve been proven to no longer have any success. Add to that the fact that the spinal cords of mice and dogs control walking in a much different way than the human spinal cord does. For them, walking is a more automatic function within the spine than it is with humans.
So what do I hold out hope for? Nothing much in the way of cures. I certainly wouldn’t be the first person to line up for them, due to potential side effects. For other spinal cord patients, I hope that there becomes more success in treatment within the minutes and hours following a spinal cord injury. When the spine is traumatized, swelling kills off many of the nerve cells. There is also a phenomenon in which the immune system actually begins attacking the spinal cord. In the future I hope that trauma can be limited to the initial damage and not spread.
Here is a sad fact for those holding out hope. Spinal cord injuries are very rare, about one in 300,000 people will suffer one in their lifetime. There are currently many more very good outcomes, meaning mortality, than there ever have been. People can suffer an injury, be stabilized successfully, receive necessary physical therapy, get a proper wheelchair and reenter society more so than ever before. This all means that there is very little financial incentive for developing a cure for such a rare disease. There is also much more money to be made in the lifelong treatment of people with severe spinal cord injuries than there is in curing them. This is the case with many other ailments where there is more money to be made in the ongoing treatments or medications than there is in a cure.
There’s nothing inherently wrong with this. That’s just the way business is. It’s the reason that much of the funding for such things comes from grants and charity rather than an R&D budget.
I remember when I first read about the mice and the 13 months. I had been injured about 11 months at that point. It shocked me to my core and literally knocked the wind out of me. I think that was the first time that I began to lose hope that I would ever walk again. It hurt so much at the time, but at least I was willing to take in the information rather than staying willfully ignorant and sitting around waiting. It also may have kick started me to begin looking at things a bit differently. If this was how things were going to be, I’d damn well better find a way to make it work. And so that’s what I do and that’s what I continue to do.
