Happy Halloween Everyone!
We decorated the house today and are in costume as we speak (we are bikers! - yes, not very original, we know). Chris is still taking allergy medication for the hives that are still down both of his arms. He has also developed bruising down one arm, which we think is due to his low platelet level. We are planning on giving the hospital a call tomorrow just to make sure we have nothing to worry about.
Chris is currently at his "Nadir", which means the low point in time between chemotheraphy cycles in which you experience low blood counts. From this point onward his blood counts should be going up.
Recently we have been recieving a bunch of questions from people following our blog that they aren't 100 per cent sure what MS is and how giving Chris a new immune system will help. To be honest, Chris and I both had no idea what multiple sclerosis was when he was first diagnosed. And until things started getting more serious I didn't even really understand the science behind it.
So here is a quick rundown of how it works. Please keep in mind this is just my understanding from reading and talking to doctors so there may be some errors!
What is MS?
Although the myelin can rebuild itself, the rate of demyelinization caused by MS is too rapid for it to keep up. The damaged parts of myelin are often called “lesions” or “plaques”.
Basically, you just need to think of a lamp: You have a lightbulb that recieves it signal from a copper wire. The wire is wrapped with plastic to protect it. If you start losing parts of the plastic the wire will start to rust and eventually the light won't be able to turn on.
This demyelinization can cause a wide range of symptoms such as:
- muscle stiffness or spasms
- cognitive problems (e.g., memory loss)
- dizziness and sensations of spinning
- mental health problems (e.g., depression)
- extreme tiredness
- difficulty walking
- bladder problems
- bowel problems
- hearing loss
- numbness and tingling
- speech and swallowing problems
- vision problems
MS has its most striking effect on motor and sensory neurons, which generally have long axons carrying information between the brain, spinal cord, and the rest of the body. Because these axons are longer, they have a greater need for the insulation myelin provides and are therefore most affected by its destruction.
What causes MS?
Nobody knows for sure what causes MS, but most scientists agree that it involves a combination of environmental and genetic factors. Different factors that are linked to MS include:
- Infection: Researchers believe that many autoimmune diseases are provoked by some kind of infection that may affect people differently who have a certain genetic makeup. The infection can trick your body's immune system into attacking your own tissues, even after the infection has gone.
- Family history: While scientisits have determined that there is no MS gene, research has shown that you are more likely to get MS if someone in your family has it.
So there is my little (or not so little) explanation of MS. Hope it makes sense!
