If My MRI Is Stable, Why Is My Walking Getting Worse?

If My MRI Is Stable, Why Is My Walking Getting Worse?

MS_Wire_Ed_Tobias
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.

The Harvard Med School study

Details of the Harvard Medical School study are reported in an article written for Multiple Sclerosis News Today by Jose Marques Lopes, PhD. The conclusion of this study is that, for some MS patients, there may be no connection between the number and size of the lesions that can be seen on an MRI of the brain and that patient’s level of physical disability.

The research found that a little over 13 percent of the patients who were studied had this “dissociation” between what the scan revealed and their disability level. Some had only a few brain lesions but lots of disability. Others had a lot of brain lesions but relatively little physical disability.

According to the researchers, patients in the low brain lesion but high disability group were prone to having a progressive form of MS, more cervical spinal cord lesions, and a lower physical quality of life. The study’s authors believe this may be due to their lesions being concentrated in the spinal cord rather than in the brain, and that’s pretty much what my neuro told me about my MS.

What about MS patients with the opposite — when their MRIs show a lot of brain lesions but they exhibit few physical symptoms? The Harvard researchers suspect these patients may be likely to have cognitive problems.

Bottom line

For the study: The researchers believe that this disparity between observable symptoms and MRI results complicates a neurologist’s ability to determine a prognosis for MRI patients.

For me: The study results, combined with what my neurologist told me the other day, explain why being told for many years that “the MRI looks great” was only half of my MS story.

  1. Thanks for sharing your doctor’s feedback. I am also in that group with a heavy lesion load. It’s helpful to hear a theory, even one that’s not particularly comforting.

    • Ed Tobias says:

      Hi Lisa,

      I’m glad that you thought the information was helpful. I, too, would rather read something that helps me understand a little more about this disease, even if it’s not always comforting or encouraging. I want to know what’s going on.

        I agree with you Ed Tobias!

        Living with SPMS (dx’d 1985 RRMS) – my biggest MS gripe would have to be my cognitive melt-downs — which are further amplified by the least bit of stress, i. e., packing a small suitcase for a WEEKEND trip. Ridiculous, I know. And then of course – I have the almost usual symptoms of major fatigue, R. Foot drop, not being able to stand very long or walk very far, mild bladder stuff, worsening hand writing, on and on.
        My walking distances as well as the amount of time I can actually stand – have been dramatically reduced since dx’d with SPMS 7 yrs ago – even though 6 annual MRI’s have shown no new dz activity or progression, and all seem pleased (dr’s and me) with the DMD I am taking, GILENYA.

        In the article – what I found most interesting and affirming – was that those with the most brain lesions seemed to have more cognitive difficulties vs. those with the most brain lesions in their spinal cord/brain stem – having the most physical difficulties.

        On an MRI – my brain lesions are so vast, that it reminds me of a crime scene reenactment on any version of Law & Order – where they replicate the blood spatter on a wall. So even learning this wee bit of information is absolute VALIDATION for me. ???

    I also have stable brain lesions. For years and years. But my disability is getting a lot worse. I still walk, but only around my small apartment. I haven’t been able to go anywhere without my scooter for years. Thanks for verifying what I always believed.

    • Ed Tobias says:

      Hi Kym,

      It sounds as if our progression has been similar, though I think I’m a but more mobile than you. I’m glad that you found what I wrote was useful.

    • Robyn says:

      I am in the same position. My neurologist is always so happy to report “no new lesions” and doesn’t ever want to address my decline! Very frustrating!!
      Years ago I had a doctor report to me that I looked “a whole lot better than my scan”, meaning she expected to see me with more disability.

  3. Jaz says:

    Good article, not sure it helps, last MRI was unchanged, but was only for comparison to brain lesions. I am lucky I guess, RRMS diagnosed in 2014, still have full mobility, but the article makes you wonder about the future, not much I can do other than take the medication and smile, accept the symtoms I have and try not to worry.

    • Ed Tobias says:

      Hi Jaz,

      I was fully mobile for many years after my DX before slowing down. But when I was DXed in 1980 there were no Disease Modifying Drugs. So, you have a better chance than I had of kicking MS in the teeth. Best of luck and stay positive.

    • Anne Seibright says:

      You can do something. You could have HSCT. With an EDSS which appears as low as yours & such a short period of time since diagnosis & is still RRMS, HSCT could halt disease progression & improve some symptoms. It’s certainly worth you researching…..I have followed hundreds of people with your level of disability/ time since diagnosis…..95% success rate. google HSCT for MS.

    It seems like they don/t really know about the connection between lesions abd MS disability I have been dealing with this since 2001 and still no answers,thanks for looking at this ED read your column always hoping for something Merlin Leine

    • Ed Tobias says:

      Thanks, Merlin. I try to write from the perspective of a journalist who also happens to have MS. I’m really pleased that you find my stuff useful.

  5. Julie says:

    It’s been seven years since my last relapse so I’ve been lucky. Supposedly I am stable according to my brain MRI’s (spinal done about every 5 years) but I definitely feel a very slow progression. I have asked the same question of my neuro regarding MRI’s. Heard the same response. Wish they’d find a cure already. Waiting has been the hardest part. Our futures are one big question mark…Thanks for the article. I am not alone!

    • Tim Bossie says:

      You are definitely not alone Julie! Keep asking questions, keep pushing for what you feel you need. And keep hoping for that cure soon. 🙂

    • Ed Tobias says:

      Hi Julie,

      Thanks for your comments. We’re all traveling the same river even though our boats may be different. The more we know about how to navigate these waters the better we all are, so let’s keep sharing our experiences.

  6. Lisaann Czarnowski says:

    Hi Ed.Lisaann here. Interesting article with perfect timing. I’m going to a little mini group informational tonight titled “Understanding MRI & the Role in Diagnosis & Treatment”. I always look forward to reading your articles.

    • Ed Tobias says:

      Hi Lisaann,

      Always good to hear from you and I’m glad to hear the timing was so good. MRIs can certainly be puzzling, (I should speak with my cousin the radiologist about them someday), so your session tonight should be interesting.

      Ed

  7. Mary Terese says:

    My lesions are in my cervical area and my MRI has been unchanged for years. I’m now SPMS with my left leg weekness, foot drop and fatigue worsening.

  8. Katie says:

    I had a MRI (brain and spine) Jan 2017 the neurologist report said ‘changes consistent with ms’. What does that really tell – nothing much that I already know.

    • Ed Tobias says:

      Hi Katie,

      I think that report may have been written by a radiologist and not by your neurologist. I’d suggest you ask your neurologist to review the actual scan with you and show you, or at least tell you, specifically what’s on the images.

      Ed

  9. Lisa says:

    Having faith in this moment I’m feeling strong to take care of my self hope soon a scientists will give us a good news.

  10. Suzanne Branch says:

    Thank you.
    For years , my brain scans have read , “consistent with ms. Little or no change.” I have gone from just numbness, but fully functioning to needing help to stand and then walking up to 15 using a walker and a belt. I can’t open, close my left hand nor raise my left arm. Still the radiologists’ reports say no new or enhancing lesions.
    Finally, one of my many ms specialists looked at the cervical spine MRI and explained that my brain was ok, but my spine was a mess.
    I wish that I read this article as my leg and arm stopped working. I felt ” crazy” for so long.

  11. Kathy says:

    Thanks for the article. 27 yrs for me. Diagnosed at 20. SPMS stage. Copaxone for 17 yrs w no change to MRI in a about 15 yrs. Just took a huge step and switched to the new infusion of Ocrevus. First dose was yesterday…hoping I made the right decision.

    • Ed Tobias says:

      Hi Kathy,

      I’m glad that what I wrote was useful. I’ve read a lot of hopeful things about Ocrevus. I have similar mixed feelings about having switched to Lemtrada, but the positives seem to outweigh the negatives for both.

      Best of luck,

      Ed

  12. Shiryl Dean says:

    This has always been my question and issue. All of my MRIs since diagnosis have pretty much been the same, but my walking has been getting worse over the last 11 years. I was told I had a lesion on my spine, but I’ve primarily only have had MRIs on my brain with no change. I guess this explains my experience.

  13. Valerie DeAngelis says:

    I just got another MRI and no changes, but my doctor said; my MS seems to be real progressive, before seeing the MRI. The person that read it said; no changes. Yet my body seems to be shutting down. Vocal cord parilized about 2 years, intestines parilized on left side, already prolapsed so had some removed.motorized wheelchair ordered by my doctor.Why no changes on MRI, but I’m much worse?

    • Ed Tobias says:

      Hi Valerie,

      I’m sorry that your MS is as bad as it’s become.

      As I wrote in my column some lesions, which create the problems that cause many of the symptoms, can be hidden on MRIs. Also, if the MRI is only done on one part of the body, for example the brain, you won’t see problems caused by lesions along the spinal cord.

      I wish you the best.

      Ed
