Why Cant We Reverse Nerve Damage
Every year, tens of millions of Americanssuffer from nerve damage, some irreparably so. Science can heal bones, grow new organsand even restore our microbiomes, but why is it so hard to fix our nerves? Hey guys Lissette here for DNews The human body posses a remarkable abilityto heal. Bones refuse, skin wounds mend, and the immune system adapts to infection,after infection. But there's one area of the body that struggles to recover after aninjury: The nervous system. Nerve damage can be some of the most debilitating and permanenttype of injury.
The nervous system is an incredibly complexnetwork used to send electrical information throughout your body. It can basically bedivided into two sections. With the brain and spinal cord making up the central nervoussystem or CNSâ€¦. and the nerves made up of fibers of sensory and motor neurons comprisingthe peripheral nervous system. Each cell in the nervous system from the tipof your finger up your arm, up your spinal column, into your brain, is very specialized.And each has a unique function on the pathway, like a circuit. If one these gets cut or injured,it's hard for an exact replacement cell to be put in in the right spot. Think aboutwhen you get a cut on your skin. If the cut
goes deep enough, exact replicas of cellswon't cover the wound, instead fibrous tissues form. which we call scars. And scars arepart of the problem in regrowing nerves, they often get in the way especially in the caseof spinal cord injuries. As part of the CNS, spinal cord injuries are notoriously difficultto heal; partially because of the way nerve cells in the CNS are made. According to the book, â€œResults and Problemsin Cell Differentiationâ€�, the CNS also has certain proteins that weirdly, inhibit cellregeneration. While this might sound like a bad idea, it's hugely beneficial overallto the formation of the CNS. These cells need
to grow exactly where they are supposed to,just one out of place could be bad. Like. think of an electrical circuit, each unithas to be in a specific order in specific place to work. If one is out of place, theintegrity of the CNS is compromised. Neurons in the CNS also lack certain cleaningcells. Nerve cells are made up of many parts, but they send signals through threads coveredin a protective sheet of myelin. These threads are called axons. Axons are the long partof the cell that reaches out to the cell next to it to send information down the line.Like arms handing the bucket down the line in a bucket brigade. So these are obviouslysuper important and need protecting. That's
where the Schwann cells come in. which areonly found in the Peripheral nervous system. Schwann cells, which aren't neurons butGLEEL cells, produce the myelin that help protect the axons. But, a study publishedin The Journal of Cell Biology found they also clean up damaged nerves making wayfor the healing process to take place and new nerves to be formed. But the problem is.these Schwann cells are missing from the CNS. What they have instead are myelin producingcells called oligodendrocytes. But these cells don't clean up damaged nerve cells at all.Which is part of the problem. So unfortunately, according to RichardG. Fessler professor at Rush University Medical
Center quot;There are currently no therapies whichsuccessfully reverse the damagequot; from injuries to the spinal cord. But research is currentlyunderway to examine the potential success of stem cell treatment, where stem cells areinjected directly at the injury site. Still, it will take a few years to see the resultsof such trials. But there are times your body can regeneratenerves. The peripheral nervous system doesn't have the same blocking proteins that the CNShas, and Schwann cells help heal the damage. So it's able to regrow nerves, albeit slowly.For instance, if you cut a nerve into your shoulder, it could take a year to regrow.By that time.the muscles in your arms could
Post Lumbar Surgery Neuropathy TheVillagesNeuropathy
When you originally presented to the office,you presented with a post lumbar surgery neuropathy, weakness, numbness, tingling, loss of sensationin lower legs and feet. We manage you here at Davis with our neuropathy program.What's been your response to the program here in our office, and how are you doing and whatwere your experiences before coming to the office with your condition? I was sufferinggreatly with back pain, I was very unsteady on my feet, I could not walk without a walkereven just a few steps, I needed the walker. The pain was just very severe. I was treated,but the only treatment I could receive down here was pain pills and I didn't like takingthe pain medication because that made me sleepy
all the time. I went to the pain andthey tried some different things too. Some patches and things and I didn't like thateither because it didn't help me. I read about the Davis and I was a little hesitantbecause of it saying chiropractic. I didn't want anybody pushing or pulling or anythingon my back. I met a woman at the pool and she told me her husband had a positive experience.He had been in pain for four years, came to the Davis and was pain free after histreatment. So I decided, Ok, I'm going to go there. So I went. I love coming here. Thepeople are wonderful for one thing. Everyone is very pleasant and upbeat. The treatmentswere pleasant, I just get to sit in a lovely
chair and have my leg treatments and havemy feet shook up on the vibrator and get zapped in the back by my s. It was wonderful.The thing was when I first started them I was hopeful, but I thought, quot;Well hmm I don'tknow I hope this is going to work.quot; I really wanted it to work because I had tried so manyother things. It did. It worked wonderfully. Now I've been through the first twenty fourappointments, finished with that, and I have improved 80%. My balance is much better Idon't have to clutch the safety bar in the shower as much as I did before. I can standin the shower in order to take a shower, I don't have to sit where I did before. I canwalk, still not a long time but that's probably
as much to my C.O.P.D as to my back. So I'mvery very pleased with everything here. I would recommend it highly to anyone. Thankyou. Well congratulations on your result we're absolutely delighted to have you here as apatient. Thank you very much Davis, I love this place!.
