MS: Who Gets It and Why

Multiple Sclerosis (MS)… some call it the MonSter, or the Beast. It is a demyelinating disease, an invisible illness, a mysterious ailment subject to many misconceptions. Who, what, where, when, why, how… all good questions.

That’s why the Multiple Sclerosis Foundation recognizes March as National MS Education & Awareness Month, and the National MS Society designated March 8-14 as MS Awareness Week.

WHO gets MS? About 2.5 million people worldwide have MS. It is estimated that 400,000 people in the United States have it, with 200 more diagnosed each week. These numbers are only estimates, because MS is not tracked by the Centers for Disease Control or any other federal agency. In fact, there is no coordinated effort at all to track the incidence of MS in the United States. The last national study of MS rates took place in 1975, and much has changed since then.

MS is more common among females and is found more often in Caucasians of northern European ancestry than in Hispanics/Latinos or African-Americans and is relatively rare among Asians and some other ethnic groups.

WHAT is MS? MS is a neurological disease in which myelin — the substance that protects neurons — is damaged, forming lesions in the central nervous system that interrupt the transmission of electrical currents to the rest of the body. Relapsing/remitting MS, the most common form at onset, causes flare-ups followed by periods of remission; there are several types of progressive MS in which symptoms worsen over time with no remissions.

Symptoms vary greatly from patient to patient — and from day to day — and include fatigue, numbness, visual impairment, slurred speech, difficulty swallowing, cognitive impairment, tremors, vertigo, pain, depression, lack of coordination, paralysis, and blindness. Some people with MS experience the worst of these, while others register barely a blip on the radar. Prognosis is near impossible.

There is currently no single definitive test for MS. It is diagnosed through neurological exam, clinical history, and a series of tests, along with elimination of other diseases. MS is not contagious.

WHERE is MS most prevalent? Northern latitudes farther from the equator see higher incidence of MS than areas closer to the equator. Exposure to sunlight and vitamin D is a factor currently being studied.

WHEN do people get MS? It is difficult to pinpoint when MS begins, but diagnosis usually takes place between the ages of 20 and 40. Due to MRI, an increasing number of young adults and children are being diagnosed with MS.

The National Multiple Sclerosis Society reports that up to 10,000 of the estimated 400,000 Americans who have MS are children or adolescents. At least that many children also have experienced at least one symptom suggestive of MS.

WHY do people get MS? That’s the big question! The cause remains unclear. MS is thought to be an autoimmune disease — one in which the immune system reacts abnormally, causing the body to mistakenly attack itself. Another theory is that a virus or infectious agent plays a role. A combination of genetics and environmental factors is one avenue that researchers are pursuing. Studies into the cause and cure are ongoing.

Researchers at the Buffalo Neuroimaging Analysis Center at the University of Buffalo are looking into the possibility that MS results from narrowing of the primary veins outside the skull — chronic cerebrospinal venous insufficiency. In CCSVI, narrowing of the veins restricts the flow of blood from the brain, causing degeneration of neurons. CCSVI was discovered by Paolo Zamboni, M.D., from Italy’s University of Ferrara. Results of a preliminary study of 16 patients with relapsing/remitting MS and eight healthy controls showed that all the MS patients, but none of the controls, had chronic insufficient blood flow out of the brain. (CCSVI and other MS hot topics will be addressed in a post later this month.) Further reading: Research Challenging What We Know about Multiple Sclerosis

HOW is MS treated? There are several disease-modifying injectable medications intended to decrease the number and severity of relapses and stave off permanent disability. Attacks are sometimes treated with steroids, and specific symptoms can also be treated. It is crucial for people with MS to implement healthy lifestyle choices, including a balanced diet, exercise when possible, rest, and avoidance of tobacco and other harmful products in order to avoid other preventable diseases.

Multiple Sclerosis has a profound effect on those who must live with it, or in its wake. The physical, emotional, and financial toll on the entire family is incalculable.

Throughout the month of March, I will offer glimpses into my own life with MS in Care2 Healthy & Green Living. While there is no such thing as a typical case, those who are familiar with MS will nod in recognition. If you are not familiar with MS, please allow us a few moments of your time during MS Education and Awareness Month, and check back here in Care2 Causes in the weeks to come.

Very informative, thank you. Over Christmas 2012 I fortunate enough to help raise awareness and money for MS by gift wrapping shoppers gifts. It was a wonderful experience.

My Dad had MS, and I have always thought it was the jet exhaust he was around for years and the jet fuel that he would get soaked with every now and then. Two very toxic substances. A friend of mine had it also and she worked at an aircraft company. Maybe they should look at environmental factors.

My sister who lived in California for many years but grew up in the Northern part of the country had severe MS. She is the only sibling of mine that had it. No one else on either side of the family had it. It is a mystery as to why Mary Lou contacted it. It was devastating for the family but they still handled it very well. Lu just would never give up and ended up falling a lot even though she had a cart to get around but it would tip over and someone had to be there to pick her up which would usually be her husband. Lu passed away February 20, 2008 at age 70. A noble lady was she and I miss her very much.

I just posted on the other page, but please check out Dr. Zamboni of Italy. You may find it extremely informative. His 'Liberation Treatment' is curing hundreds of people. If you follow through it makes sense why it is more prevalent in the northern cold climates than in the southern hot ones.
