It would be very easy - at least in terms of checking the validity of the imaging. The people involved would just follow the responsible path that all medical researchers looking at new treatments should follow
they’re not medical researchers looking at new treatments. They’re surgeons performing a routine surgery on people that have a measurable cervical issue , and they have little knowledge of ME in my understanding. It’s my understanding that Henderson and Bolognese have published a lot of stuff both on surgical techniques , diagnostic aspects like the various angles used to diagnose this.
I’m still pretty tired but will pull up this literature later or maybe you can look for it. Or maybe
@Jeff_w or
@JenB can when they get a chance. Some of what Henderson has published also discusses comorbidities like MCAS , EDS, and also discusses the clinical presentation of brainstem compression, and surgical results.
I am not a neurosurgeon but I worked alongside and referred patients to Alan Crockard, who at the time was considered perhaps the best craniocervical surgeon in the world and trained Henderson. I looked after people with CCI.
The literature around CCI is changing all the time, and I think that cci in the absence of EDS, other known disease that affects collagen, or head trauma is something that even the surgeons treating Jeff and Jen probably had little knowledge of. (To be clear, Jeff said he had EDS, but Jen didn’t, and more and more people diagnosed with CCI recently have not had EDS or head trauma ). So it’s probably either a new phenomenon or a phenomenon that has never been looked for because why would people think to look for cci in someone that has had no head trauma, no EDS, no RA, no Down syndrome, etc. I think it’s a combination of both. Probably not entirely new, but definitely skyrocketing in prevalence? Why? It really begs the question. I sincerely doubt that it is because it is being overdiagnosed. That’s one possibility. But the other possibilities are more strange. And we shall see.
But also curious, Henderson is one of the people doing these diagnoses and also surgeries. If your argument is you worked with someone who trained Henderson , you seem to be implying Henderson is an expert, or at least considered one. So then why the idea that he’s involved in a massive scam?
I have come to the conclusion that I am 90% sure that there is a major scam going on in the commercial pain control sector focused on CCI in the context of 'EDS'. There is promotional material on the net going through all the stuff about upright MRIs and cervical traction tests apparently for 'EDS' CCI in the context of very varied and vague symptoms
People also consider ME symptoms “vague” because they encompass so many different body systems. Any brainstem compression would cause pretty broad symptom set because the brainstem is involved in so many body systems. It could obviously cause autonomic issues, headaches, vertigo, seizures, central apnea, immune issues, etc. the autonomic issues alone would be enough to explain ME if you believe David systrom or David bell (sort of) , hypovolemia, hypoperfuson, preload failure—all of these could explain many of the symptoms of ME, they just need a cause. There’s a Naviaux quote about the role of the brainstem in the CDR that I need to dig up once I’m feeling better.
But since the estimate is that one person in 75,000 will have this problem there is something not right about the presentation.
Or there’s not something right about that estimate. I mean, if nobody SCREENS for cci, because it is thought to be rare, how do we know it’s really rare? Sort of self fulfilling prophecy.
The promotional material talks about upright MRI and gives example pictures. The first thing I noted is that the reason for the upright posture is to identify a Chiari abnormality - the cerebellum slipping down through the craniocervical junction. It is not to identify CCI itself.
Many of the top neurosurgeons like upright mris because the effect of gravity often shows more laxity, but one of them uses supine mris of the cervical spine. If you are curious why many clinicians use upright mris to diagnose this, many of these clinicians probably have answered this somewhere, in their research or presentations.
The other thing is that CCI is judged by an angle drawn on the image. The example shown has an angle that is said to be abnormal but the picture does not show any convincing neuropathology.
This is an interesting point. I would personally love to see a 50 year history of the use of clivo axial angle etc and what was considered to be abnormal. It does seem that some people with worse measurements are more functional than people with more mild cci , but there’s so much we don’t know about neurology that I’m not sure how to explain that. People with hydrocephalus and very little brain tissue can sometimes have normal IQs.
I think that normal ranges can have some problems with defining them in an age where chronic illnesses and various kinds of pathology seem to be rising in general. The normal ranges for testosterone, for example, are consistently being lowered. The acceptable ranges for various industrial pollutants both in the body and in the environment seem to change based on a variety of circumstances.
So I would love to see studies that both compare these angles to healthy controls but also look at them over fifty years or so. That would be great. Does that exist?
But also I do think that this is the reason clinicians don’t just use the angles, but also use the symptoms and response to traction to determine if someone’s will be a good candidate for surgery. If someone’s clivo axial angle showed brainstem compression/cci and they were running marathons, it would make no sense to open them up. But in jens case, she stopped breathing while awake. Seems like the surgery was warranted, and I’m glad she was in good hands, and didn’t wait for years of research on the connection btwn ME and CCI.
The publications by Henderson also go into the mechanisms of neural injury that happen at the cellular level from the brainstem being compressed. While that is not his area of expertise obviously, he certainly is interested in the actual mechanism of injury here rather than just looking at some angles and deciding to cut into people. I hope that Michael Van Elzakkers work on brainstem inflammation will uncover some stuff here. While there no guarantee that brainstem inflammation in the way that he is measuring would result from neural injury, it seems quite possible it would. After all, they are measuring microglial activation as a proxy for inflammation, and microglial activation occurs in neural injury. However I’m just a layperson and I don’t know if the brain would “adapt” to that neural injury with less microglial activation once it becomes chronic. It seems that maybe it would adapt and then you wouldn’t see excessive inflammation in the brainstem but instead a widespread hypometabolism resulting from the homeostat being broken OR as a protective mechanism against the oxidative stress caused by neural injury.
I actually don’t think cci is the ultimate cause of ME so I’m not some kind of crusader here. But I’m almost certain it’s involved intimately. The problem is what is causing it? I’m sure there’s something upstream and this is what’s concerns me with my resolving it by surgery, as o believe whatever caused the cci could cause further regeneration of connective tissues lower in the spine and ultimately cause a relapse if The cause of the connective tissue problems isnt discovered. There’s lots of conjecture on this but we don’t even have the basics of studying cci in ME yet, so we have to start there.
