Why does treatment help so fast ?
What is "No, " in my post? I did not mention any time measurement - neither minutes or hours or days. Read more carefully next time.eric593 wrote:No, Dr. Sclafani says that effects of contrast only last a few minutes (not hours, days, etc).Malden wrote:Like dr.

You suggest in your post that "onesickrace's" experience was what Dr. Sclafani spoke about, a reaction to contrast dye. But that isn't the case, since Dr. Sclafani suggests a contrast effect only lasts for minutes whereas "onesickrace's" improvements began well after the first few minutes of contrast dye being injected. So, contrary to what you state, the contrast dye could not be the cause of "onesickrace's" improvements based on Dr. Sclafani's knowledge of how long a contrast effect lasts, not long enough to be connected to "onesickrace's" improvements which began and remained after the procedure had ended, beyond the timeline Dr. Sclafani notes could be connected to the contrast dye.Malden wrote:What is "No, " in my post?

But I think that you read and understood my comments just fine the first time without the elaboration, you just wanted to add the barb in about me improving my reading. You only chose to DISREGARD the timeline that Dr. Sclafani limited a contrast reaction to when you responded, possibly to try to garner support for your position that was simply not contained in Dr. Sclafani's statement.
It seems thing are getting a bit heated!!
I started this thread because I didn't know if there was a predominant theory regarding the sudden improvements that some people experience. It seems that there isn't a predominant theory but I am still interested in anyone's theory.
I not interesting in arguing. I thought we were all in this together.

malden,
on numerous occasions, ive had the contrast injected during imaging.. this feeling was after they pulled the wire out of my vein and no imaging was done anytime after the procedure. also, i know that everytime ive been given the contrast, i can taste it... and this time i couldnt. thirdly, it was a completely different sensation than just the warming that comes from contrast. it was almost a tingly sort of warm sensation starting at both shoulders and taking about 2 minutes to get to my finger tips. i even wondered how hot it would get.
just to throw it out there, i had the procedure done on my azygous vein and nt my jugulars, so maybe this has a different effect than if it were my jugulars...

Thank you onesickrace for explaining your experience. If this warming is not comming from contrast, then it must be, as dr. Sclafani wrote, from sympathetic nervous in origin.onesickrace wrote:on numerous occasions, ive had the contrast injected during imaging.. this feeling was after they pulled the wire out of my vein and no imaging was done anytime after the procedure. also, i know that everytime ive been given the contrast, i can taste it... and this time i couldnt. thirdly, it was a completely different sensation than just the warming that comes from contrast. it was almost a tingly sort of warm sensation starting at both shoulders and taking about 2 minutes to get to my finger tips. i even wondered how hot it would get.

Sticking with basic science
Lets repeat the basic roles of CSF:
- provide oxygen
- provide nutrients
- remove waste (CO2 is a waste product)
Logically any early and on-going improvement after de-stenosis is most likely to be linked to CSF flow. It will take years of research to establish the exact process.
My educated guess is that removal of waste products by opening of veins plays a significant role. If waste is not removed then the brain slows down in a negative feedback loop. Maybe, opening veins removes waste products and permits the brain to work at greater speed, giving the quick recovery in fatigue and brain fog that patients have reported as clincial experiences.
The role of hormones (proper androgen signaling) mentioned by pairOdime is interesting. I agree it could be a medium term (days/weeks) impact rather the short term (hours/days). It does make research more complex and time consuming.
De-stenosis is unlikely to be a simple single effect (our bodies are more complicated that this). It will take the researchers a long time to explain what is happening in CCSVI. Also please remember that if one of the factors is shown to have a role that does not mean the others are excluded. Explaining CCSVI is very complex, please do not try to over simplify it.
Lets remember this simple concept:
CCSVI syndrome has stenosed veins as a symptom. Any extracranial restrictions may be safely de-restricted (de-stenosed) using balloon venoplasty.
To de-stenose or not to de-stenose, that is the question for pwMS. Whether you will take the risk of balloons.............
Kind regards,
MarkW
PS Malden (Colin Rose) is a naysayer on CCSVI. He says he wants proof/trials. This is designed to mislead as CCSVI is syndrome in which the diagnosed symptom is treated, not the etiology of MS explained.

Interesting info
Cece posted (in another thread):
Cheer also posted (possibly in a different thread) that the doctors doing perfusion/fMRI work (which must be Dr. Hubbard?) are finding that the ratio of blood flow in normal brains compared to MS brains is 2 to 1, quite a dramatic difference.
I thought the perfusion work was being done by Mark Haacke's group. If they find that de-stenosis increases blood flow (better CSF flow) by two-fold then de-stenosis becomes mainstream for pwMS. Research and argument over MS etiology is side stepped.
Does anyone have any details ?

It has been posted elsewhere but Zamboni spoke at much greater depth about hypoperfusion at Barcelona:

"...ratio of blood flow in normal brains compared to MS brains is 2 to 1..."
is totaly false and fictitious claim, not proven at all.
Re: Interesting info
It wasn't said which group it was, I was only guessing Dr. Hubbard because of his work on fMRIs and pre- / post- procedure oxygenation.MarkW wrote:I thought the perfusion work was being done by Mark Haacke's group.

Would perfusion data alone really be compelling enough to get this mainstream?
this matches my own experience. I can go for about half an hour, and then the legs just stop. then I have to sit down and rest a bit, eat an apple or drink a glass of coke. after, I can go again perhaps for 15 or 20 mins. taking a bit of sugar makes the hell of a difference. this has been the case many years now.Cece wrote:There has been much talk about CCSVI's effect on oxygenation of the brain, I always want to pipe up and say don't forget about the glucose needs of the brain too. That too is likely depleted when outflow is blocked.
Some previous thinking on fast improvements was that it could be placebo, vascular in nature, or autonomic nervous system (?). Also if fatigue is lifted, then that can account for some improvement too possibly, such as being able to walk farther than before.
A big difference is if the neurons are "merely" damaged or undernourished, they can be restored, but if the neurons are gone, then they can't be brought back.
as you say, the implications of this could be BIG!! and indeed would seem to point at another mechanism than neuron death that explains the effect. a low glucose level because of slow blood flow would seem a plausible explanation. whow Cece, you have just given me an extra dose of hope..
I'm like that too, Leonard, it's why I focus on the glucose side of CCSVI! It might tie in to heat intolerance too; glucose levels in the blood vary more dramatically when it's hot outside, it's something that diabetics have to take into account in the summer. I am also trying now to have some light protein before I go to bed, since sleep is in particular a "danger" time with poor blood flow. If you read Cheer's research on REM sleep, it tied into this because REM sleep takes a lot of glucose and in glucose-deprived brains, it could be why some pwMS report not dreaming and why some liberatis report a return of dreams.Leonard wrote:this matches my own experience.

Cece, thank you! I can confirm this. My sleep was terrible, lots of headaches, night spasms, many times out of bed to urinate, most of the time half awake. Until I got liberated. And indeed, I started sleeping and dreaming again, I mean really dreaming as if my young years had come back. Until things restenosed ... and restenosed..Cece wrote:I'm like that too, Leonard, it's why I focus on the glucose side of CCSVI!
