Brain regeneration in kids with cerebal palsy: feeling regroovy
The other day I took Max to see a cerebral palsy specialist, Joseph P. Dutkowsky, MD, at Columbia University. Dr. D., as he refers to himself, is the Associate Medical Director of the Weinberg Family Cerebral Palsy Center, amongst other impressive titles. He is an orthopedic surgeon but he has a big-picture overview of kids and adults with CP, as he's spent his career working with them. A mother of a girl with CP and advocate I met through social media, Michele Shusterman at CP Daily Living, had recommended him (and for that, I am forever grateful).
Dr. D. is a remarkably personable doc. Forget bedside manner—he was funny, charming with Max, and charmed by him. Max told him about his upcoming trip to Chicago, and proudly showed him the posts he's written here. Dr. D. called up the images taken of Max's brain when he was several old; I'd brought the discs. He glanced at the images and said to Max, "Let's have some fun!" Then he showed him where his eyeballs were on the scan. Max wanted to know why he had no hair.
I gave Dr. D. the background: The stroke at birth, the grim news we were given by the bigshot pediatric neurologist, the young intern who'd offered some hope when he talked about the plasticity of the brain. Max commando crawled at around 18 months, crawled on all fours at two, walked at three. He's had Botox over the years to alleviate tightness in his right hand, but we haven't needed it lately since it's loosened up. (You may recall my Mommy & Me Botox Clinic idea: A shot to help your child with CP, a shot for you to remedy the wrinkles caused by all that worrying.)
Dr. D. used a word I'd never heard before, "regrooving," a term he coined. As in, Max's brain had formed new pathways around the damaged areas—so that even if the original "insult" hasn't healed, other parts of the brain were compensating. He thought Max had done some major regrooving. "He walks beautifully," he said. He was impressed by his reading, including the fact that he was able to see the tiny type on my iPhone. He felt Max's muscles and was surprised that they didn't seem so stiff at all. He said he didn't present as having four-quad spastic CP, since he didn't detect hyperreflexia and clonus in him (involuntary muscle contractions and relaxations). Max's nonstandard pattern of movement is more asymmetrical mixed quadriplegic CP—but as he noted, "Since this sounds rather unhelpful, with a child like Max I just rely on descriptions, not terms."
That goes right along with what Max's pediatric neurologist has always told us: Look at what he's doing, not at his medical records.
Dr. D. pointed out that Max didn't have a whole lot of awareness of his right hand, which therapists tend to describe as his "helper" hand. This has to do with the damage in the parietal lobe, which control's self recognition or whether you're aware of what is part of you.
I wondered about how much Max's physical abilities would improve—whether he might gain more flexibility in his arms, whether his fingers would be more agile, whether his oral motor function (speech, eating, chewing, swallowing) would improve. "I have no reason to suggest that Max has plateaued," he said. Dr. D. couldn't give an answer, because no doctor can. In some ways the brain is still a mystery, even to the best experts. As the doctor noted in a followup email, "To what age can uninjured parts of the brain keep on compensating for damage? How much? For what functions? these questions are up for grabs and are why we need the National Institutes of Health to take CP seriously and give it the research funding compensatory to the nearly one million citizens with CP in the U.S. It's time."
During the visit, Dr. D. asked about Max's eyesight. It's normal now, but as a baby his focus was slow to come in. I can still remember bending down to say hello to him in his stroller. "Max! Max!" I'd say and I'd get sad that he wasn't able to look at my face, although I knew he heard me because he'd smile. He also had a habit of staring straight into the hatlights of our living room ceiling. That's a sign of Cortical Visual Impairment (CVI), which came up during our visit.
CVI doesn't have to do with eyesight but, rather, how the brain processes what the eye takes in, and is common in kids with cerebral palsy. (CP Daily Living has an excellent series and resources on CVI.). This might explain why math presents a major challenge to Max, since sorting visual information (say, stacked numbers in addition) is difficult. Dr. D. recommended he get evaluated by a teacher of the visually impaired, as part of his IEP.
I took this in pretty calmly. If Max does have CVI, then we'll better understand how to teach him, guide his therapy and organize his environment so his brain can more efficiently process what his eyes are seeing. Being on a high from the regrooving talk also helped buffer the mention of CVI.
On some level, I don't need a doctor to tell me how well Max is doing, because we were told the worst when he was born. Once your baseline expectations for your child are at rock bottom, there's nowhere to go but up. But really, it is cartwheel-inducing when a doctor says your child is doing well.
I'm sharing all this not just to raise awareness about CVI or because I'm happy (SO happy) about the regrooving, but also because I wish I'd heard more about brain plasticity when Max was a tot and I was at my most anxious about him.
When Max was two years old, we discussed the possibility with his pediatric neurologist of getting a followup MRI to the one he'd had in the NICU. And we decided: What was that point? If the results didn't show much change in his brain since the stroke, then we'd get depressed. And if the results did show that cells were springing up around the damaged areas, like green grass cropping up after a long, gray winter, well, then, it wouldn't have told us much we didn't already know about Max's functioning. He's never had another MRI in his life.
I am an optimistic person by nature, but the NICU doctors left me feeling bleak about Max's future. My main source of hope was hearing about older kids who'd had strokes and cerebral palsy and other special needs who were doing OK for themselves. I needed real-life proof of the brain's potential to regenerate. I needed to believe. Now that Max is that older kid doing OK for himself—a kid who is very regroovy—I hope he gives parents out there the hope I once desperately sought.
Maybe the CVI Max might have had in early childhood got regrooved and is no longer an issue. I don't want to gainsay a CP specialist, but here's what I'd want to ask him: How can a kid with CVI have a spectacular visual/spatial memory? That's the very stuff he ought to have difficulty processing! And how can he recognize the similarity between the shape of a letter of the alphabet that he'd only seen on paper and the shape formed by a structure of a swing set? That's very sophisticated visual processing (and, by the way, was one of the first things you blogged about that made me realize that Max had a whole lot more going on cognitive than I had, mistakenly, assumed)!
ReplyDeleteVisually, Max seems to get both the big picture and the details.
Yes, CVI could explain the math problems, but math problems are common in people with no visual processing difficulties.
And about getting an MRI--that would show new cell growth or the lack of it, but it wouldn't show how the existing cells may have (re)connected and repurposed themselves to support Max's impressive cognitive processing.

Phyl, I so appreciate it when you weigh in. From what I understand after reading up on CVI, yes, Max does not present typically as having it now. We'll get it checked out, to be sure. I am impressed you remembered the time he saw the "M" in the swingset!
DeleteEllen, it's not that I have such a prodigious memory (in fact, I couldn't remember whether the letter was M or A), but that the event was so striking in a shark-fin-peeking-above-the-surface kind of way--it just had to mean that there was so much significant unseen stuff going on underneath. To me, it meant that Max could see similarities between something he'd learned in a very specific context and something he observed in an entirely different setting, on his own with no prompting, and despite changes in scale (tiny letter vs big swing set), materials (text vs 3-D construction), function (reading vs swinging), etc. In other words, the exact opposite of rote learning! Plus, it showed Max's interest in and engagement with his world that was like--well, like a kid interested in and engaged with his world. I thought it was an amazing peek into his mind at that moment, so the memory stuck.

What kind of human body sorcery is this? This is cool.
ReplyDeleteThe magical powers of the brain!
DeleteHi Ellen, your blog was such a comfort and help to me and gave me the hope I desperately craved in those early days, now 5 years on and see how well my daughter is doing I have learned patience and learned to let Jessica show me the journey. I am so happy for you and max and a big heartfelt thank you.

Sharon, this is wonderful to hear. Thank YOU!
DeleteRegroovy! Go Max!
ReplyDeleteVictoria
Thrilled over the regrooving. And everything else. Go, Max. Go, Ellen. You are both groovy!
ReplyDeleteI'll take that! xo, PD
DeleteThis is all excellent news. Hurray for awesome doctors that give hope!
ReplyDeleteI was born two months early and spent three months over at Columbia Presbyterian; at the time their NICU was brand-new (I was born in '79). My parents still sing the praises of that hospital. :)
ReplyDeleteThanks for the info and links about CVI. For years, people working with my son would say, "what's with his eyes?" I would say CVI impacts him as much as CP. Now I have a name for it. He is 13 and still has difficulty with facial recognition. I was encouraged to read that it is often late to resolve.

The brain usually remaps itself whenever a part is injured. This is seen alot in stroke patients and head trauma war veterans. Its nothing new.
ReplyDeleteOf course it's nothing "new." This post was about the regenerating Max's brain has done, with explanations for those who aren't familiar with that process. I sure do love Dr. D.'s "regrooving" terminology, so much more picturesque than "brain plasticity."
DeleteWhen the neurologist tells you your child will likely not eat (orally), walk, or talk, as our neurologist did when our son was finally going home after a premature birth and 100 days in the NICU, remapping is exciting and new. For some reason, his remapping was more of a celebration than my mom's remapping when she learned to eat again after her stroke. (Of course, my son's remapping took many more years - he stopped using his g-tube at age 8.)

Yea nothing new. It'S just learning. And current therapies don't even make the most of it...biofeedback, that'lll re grove your re groving
DeleteLOVE this blog post. Brain regeneration/re-mapping is such an important topic that often does not get enough coverage. It is this topic in particular that I have shaped my entire career, and now my own therapy clinic around (I am a physical therapist who specializes in intensive outpatient services for individuals with neurologic disorders).
ReplyDeleteIf anyone is looking for more information regarding brain plasticity and re-mapping, I would highly recommend the following books: The Brain that Changes Itself by Norman Doidge and Spark by John Ratey. Spark is less technical and "information dense", but they are both wonderful books that I suggest to all of the families who come to my clinic.
