Why would walking deteriorate if someone’s MRI is stable?
During a routine exam with my neurologist recently, I asked her a question I’d never thought to ask before: “Why do you order regular MRIs of my brain, but not of my spine?”
Interestingly, within a few days of my exam, a Harvard Med School study was released that addressed a similar question: Is there always a link between the level of physical disability in some MS patients and the amount of lesions in the brain?
What my doctor said
My neurologist’s answer was pretty simple. Disease progression in parts of the body that are controlled by nerves along the spinal cord, such as the legs, is usually noticed by a patient physically before the progression can be seen on a spinal MRI. On the other hand, MS disease progression can be spotted on an MRI of the brain before it’s noticed physically. So, by regularly doing brain scans, a neurologist may be able to halt that progression by changing DMDs, for example, before it has a chance to have a physical impact. Doing a spinal scan doesn’t present the same opportunity.
