Welcome! This blog contains research & information on lifestyle, nutrition and health for those with MS, as well as continuing information on the understanding of the endothelium and heart-brain connection. 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 auto-immune paradigm of MS, and continues the 20 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

The brain contains 400 miles of blood vessels....

A year after Jeff was diagnosed with Multiple Sclerosis, I wrote several university researchers regarding MS as a vascular disease of endothelial dysfunction.  One of these researchers was at my alma mater, the University of Rochester.  I had first read about his work in our alumni newsletters, and later on pub med. link

Berislav Zlokovic was initially inspired to understand the blood brain barrier's role in neurodegeneration after losing a dear friend to ALS.

"The vascular system is crucial to health -- it's how oxygen and other nutrients are delivered to cells, and how toxins are removed," said Zlokovic, who is professor of Neurosurgery and Neurology and director of the Center for Neurodegenerative and Vascular Brain Disorders. "Any damage to the vascular system is a serious threat to the organism. It's clear now that the vascular system is certainly involved in the development of ALS."
Zlokovic first began doing research on the disease in 2004, when a former classmate from medical school who had been diagnosed with ALS and was looking for new treatments contacted him. By the time his friend died two years later, Zlokovic was well underway in studies investigating the possible role of the vascular system. link

He has been one of the premiere researchers looking at how the vasculature is implicated in the breakdown of tight junctions in all diseases of neurodegeneration.  I wrote to him about Dr. Swank's prior research on capillary fragility, and how I thought it made sense when observing the petechial bleeding on my husband's legs, his enhancing MS lesions on MRI, and the possibilty that the cause of both was systemic endothelial dysfunction.
(Swank RL. Subcutaneous hemorrhages in multiple sclerosis. Neurology. 1958; 8: 497-498.)

Dr. Zlokovic did not reply to my intial inquiry, but we did eventually connect after his presentation at the ISNVD as the keynote speaker, 2011 in Bologna.  He soon left the U of R for the University of Southern California's Keck School of Medicine.

I was thrilled to see that his lab has recently received $25 million in grants to study how leaky blood vessels in the brain contribute to Alzheimer's Disease.  link

Berislav Zlokovic, MD, PhD, a pioneer of the theory that fixing the brain’s leaky blood vessels will prevent Alzheimer’s disease, has received four grants totaling up to $24.9 million over five years.
The funding allows Zlokovic, director of the Zilkha Neurogenetic Institute, to attack from different fronts the blood-brain barrier, a gatekeeper that prevents toxic substances from entering the brain.
“The brain contains 400 miles of blood vessels that can stretch from Los Angeles to San Francisco,” said Zlokovic, chair and professor of physiology and biophysics at the Keck School of Medicine of USC. “If there is a leak along this vascular tube and the pothole is, for example, near the hippocampus — the center of learning and memory — that can contribute to the development of dementia and Alzheimer’s disease. We can delay the onset or slow the progression of Alzheimer’s if we are able to fix leaky capillaries when they first start, some 10 to 15 years before Alzheimer’s symptoms even surface.”

But at the same time, I'm deeply saddened by the realization that we are still in this same place----sixty years after Dr. Swank first noted leaky capillaries and petechial rashes in people with MS and successfully treated this issue in many patients with diet and exercise. link   Thirty years after Dr. Franz Schelling discovered the venous connection to MS and inspired Dr. Paolo Zamboni to look at jugular reflux in people with MS.  link  It sometimes feels like an endless cycle of discovery and amnesia, as researchers uncover, and then willfully bury or forget the vascular connection to diseases of neurodegeneration.

“The blood-brain barrier’s leaks allow many blood-derived toxic products, cells and pathogens to enter the brain and directly damage brain circuits involved in memory and learning,” Zlokovic said. “Additionally, bad proteins that normally are ejected from the brain, such as beta-amyloid, have to struggle against the flow of traffic. This situation can eventually lead to ‘a second hit’: Beta-amyloids and tau tangles remain in the brain and cause damage that become evident years later.”


The research will determine the structure of the perivascular space, how cerebral brain fluid reacts to changes in brain equilibrium and blood-brain barrier leakage. The ultimate goal is to identify therapeutic targets for the treatment of small vessel disease of the brain, which may contribute to cognitive impairment.
I honestly hope Dr. Zlokovic and his team find new therapeutic targets.  They sure have a bunch of money to do so.  However, researchers might do well to also look at mechanistic issues behind these leaky blood vessels.  Venous hypertension and CCSVI were contributing to the breakdown of my husband's blood brain barrier.   Venoplasty to repair his jugular veins resulted in disease reversal for him--with no new lesions and a reversal of gray matter atrophy.   The spots on his legs, and the spots in his brain were connected.  Diet and exercise have continued this virtuous cycle of healthy cerebral perfusion, shear stress, and endothelial cell health. 

Don't wait for this ongoing research loop to end with some new blockbuster drug.  There are things you can do today, to help heal your endothelial cells and limit the breakdown of capillaries.
Promise.   link

  1. Where in this big world, covered with the even bigger web of cruel pharma, will we go to find the venoplasty piece of the puzzle?

    1. There are vascular doctors out there who will examine and treat patients, but they are afraid of CCSVI connections, because of what happened to Jeff's IR and others. Diagnosis and treatment needs to be called DVA, or venous stenosis, or venous hypertension, or central venous disease. Here are doctors in China who are treating 15 patients with venous headache and intracranial hypertension with jugular stents. Exactly the result my husband has had. https://www.ncbi.nlm.nih.gov/pubmed/29114973

    1. No, Jeff was the first patient treated in North America, at Stanford University, where I took Dr. Zamboni's research in 2008. Here's our story: https://www.youtube.com/watch?v=Z_IGQrhyAAE&t=6s

  5. Hiv disease for the last 3 years and had pain hard to eat and cough are nightmares,especially the first year At this stage, the immune system is severely weakened, and the risk of contracting opportunistic infections is much greater. However, not everyone with HIV will go on to develop AIDS. The earlier you receive treatment, the better your outcome will be.I started taking ARV to avoid early death but I had faith in God that i would be healed someday.As a Hiv patent we are advise to be taking antiretroviral treatments to reduce our chance of transmitting the virus to others , few weeks ago i came on search on the internet if i could get any information on Hiv treatment with herbal medicine, on my search i saw a testimony of someone who has been healed from Hiv her name was Achima Abelard and other Herpes Virus patent Tasha Moore also giving testimony about this same man,Called Dr Itua Herbal Center.I was moved by the testimony and i contacted him by his Email.drituaherbalcenter@gmail.com We chatted and he send me a bottle of herbal medicine I drank it as he instructed me to.After drinking it he ask me to go for a test that how i ended my suffering life of Hiv patent,I'm cured and free of Arv Pills.I'm forever grateful to him Drituaherbalcenter.Here his contact Number +2348149277967...He assure me he can cure the following disease..Hiv,Cancer,Herpes Virus,Lyme Disease,Epilepsy, ,Bladder Cancer,Colorectal Cancer,Breast Cancer,Kidney Cancer,Leukemia,Lung Cancer,Non Hodgkin Lymphoma,Skin Cancer,Uterine Cancer,Prostate Cancer, fibromyalgia ,ALS,Hepatitis,Copd,Parkinson disease.Genetic disease,Fibrodysplasia disease,Fibrodysplasia Ossificans Progressiva,Fluoroquinolone Toxicity Syndrome,Inflammatory bowel disease ,Huntington's disease ,Diabetes,Fibroid...
