Welcome! This blog contains research, information on lifestyle, nutrition, dietary supplements and health for those with MS, as well as continuing information on the understanding of CCSVI and cerebral hypoperfusion. This blog is informative only--all medical decisions should be discussed with your own physicians.

Almost all of MS research is initiated and funded by pharmaceutical companies. This maintains the EAE mouse model and the immune paradigm of MS, and continues the 15 billion dollar a year MS treatment industry. But as we learn more about slowed blood flow, gray matter atrophy, and environmental links to MS progression and disability--all things the current drugs do not address--we're discovering more about how to help those with MS.

To learn how this journey began, read my first post from August, 2009. Be well! Joan

REAL breakthroughs in MS research

It's been a busy month for MS research.  I wanted to give a brief overview of the new publications coming out in vascular journals, linking CCSVI and MS to slowed cerebral blood flow, changes in cerebrospinal fluid flow and coagulation factors.

As much as neurologists and immunologists continue to claim this exploration is dead, finito, over---there are still dozens of publications in press or being published which elucidate the vascular connection of CCSVI to neurological disease.  This exploration is far from over, as more and more international investigators join in the exploration.


1.  The International Society for Neurovascular Disease (ISNVD)--a multi-disciplinary group of researchers, has published their position statement on recommendations for multimodal noninvasive and invasive screening for detection of extracranial venous abnormalities indicative of CCSVI.

The full text is available here:

This position paper is extremely important, because it addresses the variablity of findings made by other researchers examining impaired venous flow in people with MS---and gives the first ever standardized imaging and evaluation recommendations.  It is written by some of the leading venous and imaging experts in the world.

The ISNVD recommends the use of a multimodal noninvasive and invasive imaging approach to optimally identify extracranial venous structural/morphologic and hemodynamic/functional abnormalities indicative of CCSVI. Creation of more quantitative imaging criteria are needed for further characterization of these venous abnormalities. Screening and monitoring of these venous abnormalities with the use of a combined noninvasive and invasive imaging approach should help establish the actual incidences and prevalence of extracranial venous abnormalities indicative of CCSVI in various populations. In addition, a multimodal imaging approach will address whether these abnormalities can cause significant hemodynamic consequences for intracranial venous drainage. The proposed noninvasive and invasive imaging protocols represent a first step toward establishing and validating the criteria for detection and monitoring of extracranial venous abnormalities indicative of CCSVI in open-label or double-blinded randomized controlled studies. The ISNVD recognizes that the rapidly evolving science and growing interest in this field will facilitate a refinement of these protocols in the near future.

2.  Another international collaborative effort looks at cerebrospinal fluid (CSF) dynamics in MS, using phase contrast MRI.  At the helm of this research is internationally recognized imaging expert, Dr. E. Mark Haacke.

This research separated pwMS into two groups, those with stenotic internal jugular veins (ST), and those without stenotic IJVs (NST) Changes in outflow was noted in those with stenotic veins.

The delay between the beginning of beginning of systole and the CSF outflow was higher in ST compared to NST MS. Less IJV flow was observed in ST vs NST MS. None of the measures was different between the different MS phenotypes. These results suggest that alterations of IJV morphology affect both IJV flow and CSF flow timing but not CSF flow amplitude

3.  Tying into this impairment of CSF outflow dynamics, another recent publication found that the third ventricle in the brains of those with CCSVI was much larger than in healthy controls on MRI.   The third ventricle is one of four ventricles in the brain, and is filled with cerebrospinal fluid (CSF).  In normal brains it is a narrow cavity and CSF flows freely through in a timely manner.  In those with hydrocephalus or normal pressure hydrocephalus, this ventricle expands.

This buildup of fluid can damage the brain.  And the third ventricle is enlarged in those with CCSVI, indicating a lack of timely venous flow is impacting CSF flow.

In the MS–CCSVI group, the third ventricle diameter was 6.2±1.7 mm (from a minimum of 2.5 mm to a maximum of 9.2 mm, with a median of 6.3 mm, and a mode of 6.0 mm). Our data showed that 29 patients (88%) had an increase in third ventricle diameter, whereas only four patients (12%) had physiological size (less than 4 mm) comparable to all healthy control group subjects (27.28%). These results show that the increase in the third ventricle diameter could represent a criterion of positivity of neurological disease in patients with CCSVI.

4.  Finally, a group of vascular researchers look at how successful endovascular treatment of CCSVI changes the blood.  The fact that MS is related to higher levels of fibrin, ET1 and other markers of hypercoagulation and endothelial dysfunction has already been firmly established.

http://ccsviinms.blogspot.com/2012/11/whats-blood-got-to-do-with-it-nov.html

This group wanted to see if these blood markers changed, once normal venous flow was established.  They were.  In fact, lower coagulation activation status was associated with a better clinical outcome.  Another connection to the blood and endothelium.

Coagulation activation and endothelial dysfunction parameters were shown to be reduced at 1 month and stable up to 12-month follow-up, and they were furthermore associated with a good clinical outcome. Endovascular procedures performed by a qualified staff are well tolerated; they can be associated with other currently adopted treatments. Correlations between inflammation, coagulation activation and neurodegenerative disorders are here supported by the observed variations in plasma levels of markers of coagulation activation and endothelial dysfunction.

There is much movement in the study of how impaired venous return affects the brain for those with CCSVI/MS, and how treating this impairment improves clinical outcomes.  I live with anecdotal proof.  Jeff is now almost six years past his endovascular treatment and repair of malformed jugular veins and dural sinus.  He is jogging, traveling the world, working more than full-time, with a reversal of gray matter atrophy.  His third ventricle looks normal on MRI, he has had no further MS progression.  His coagulation numbers went from severe hypercoagulation, to normal.

There is a connection.  We will not let this research slip through the cracks.
stay tuned,
Joan

  2. ma tuo marito per ridurre e normalizzare la fluidificazione sangue, normalizzando il fibrinogeno e rigenerare le cellule endoteliali, cosa ha fatto o fa, ad hoc ?

    1. Jeff had his venous malformations repaired in May 2009 at Stanford. He also does cardiovascular exercise to increase shear stress, he eats an organic whole food diet (no processed foods) gets at least 15 mins. daily of UV rays (to increase nitric oxide and vitamin D), has reduced stress, gets good sleep, and follows the Endothelial Health Program. All of these factors have worked together to maintain health and stability. http://ccsvi.org/index.php/helping-myself/endothelial-health

  3. Thank you, Joan, for this compilation of studies done by real researchers, who want to get the truth, without negative agendas! I am another example of anecdotal proof, and yet none of the MS Specialists at the MS Clinic at the University of British Columbia, where I attend for annual examinations, have made an effort to look more closely at my case. When I say examinations, I am overstating--they are perfunctory visits with a few questions and a few basic neurological tests. I just hope they get some evidence from the clinical trials--they certainly have not been thorough in examining my case.

  4. Great point you make there. Very nice POST.. I like your perspective on this subject.
