Multiple Sclerosis

 

As a teenager I remember the Montel Williams Show, his deep quest to get to the root of his guests problems was refreshing and sometimes hilarious. Then one day his show came to end because of a disease, Multiple Sclerosis. During that time it was minimum research and therapy for the disease, but Montel became an MS spokesperson and created a nonprofit organization to fund research and educate the public. There is no known cure for MS but there are several different therapies which has increased the life expectancy of people infected. As with all my blogs I try to explain diseases in the simplest way possible, so that everyone can be informed. So let’s start with the basics…

Multiple Sclerosis is a disease in which your immune system attacks the protective sheath called myelin that covers your nerve cells in the brain and spinal cord. The damage to these cells are irreversible and slowly destroys the connection of the brain to the rest of your body.

Damage to the myelin sheath causes permanent neurological damage. Symptoms include: tingling in the hands, muscle spasms, difficulty in moving, problems with speech or swallowing. Therapy requires injections of interferon beta which reduces the inflammation caused by MS and allows the white blood cells to cross the blood brain barrier reducing lesions in the brain. An MRI that shows several plaques (lesions) in the brain represents the advanced stage of the disease.

The disease affects women disproportionately, it’s twice as common in woman ages 20-50 than men. Research  suggest that woman have a higher genetic variation that causes the increase production of interferon gamma, interferon gamma aggravates MS by promoting tissue damage and inflammation. Another study in Italy found that testosterone may be protective which is a reason why men develop the disease later in life. Although woman have a higher a rate of developing the disease, men MS attacks are more severe and progressive.

The direct cause of MS is unknown but studies suggest that it is a combination of genetic vulnerability and environmental triggers. Environmental triggers such as cigarette smoke, Epstein Barr virus and excessive drinking may cause the disease to develop. Individuals with a family history of MS are 20 times more likely to develop the disease, but genetics is only one part of the picture; 80 percent of people with MS do not have a family history.

If you have relatives with the disease or if you are currently diagnosed with MS, it is a not a death sentence. Lifestyle choices can make a difference in the quality of life, genetically vulnerable individuals should avoid cigarettes and commit to exercise and healthy food choices. Diagnosed patients should continue aggressive therapy after an MS attack, the interferons can replenish the myelin sheath cells to prevent further neurological damage.

Currently there are several thousand research labs conducting experiments and a simple blood test will be used for detection instead of an MRI that usually shows neurological damage.

I dedicate this blog to the memory Bria Hargrove a young woman who was a fighter all the way, hopefully these words will inform and educate people about the disease.

 

 

thesciencegirl RUNS

My BIB!!!

In April of 2012 I joined a running group call BGR (black girls Run), this group is dedicated to the health and fitness of African American women, by coordinating and maintaining daily running groups across America. So far I have ran 109.6 miles!!! Recently I just completed my first marathon that included a bib and T-shirt (every runner loves the t-shirts), although the marathon was 5.6 miles I left feeling empowered and also addicted to the sport. Being a scientist and also a woman who loves to ask questions, I wanted to know why am I addicted to running when during the course of the run, I sweat, yell and vow to never do it again. So I started my research with a basic definition what is running….

Running is a means of terrestrial locomotion allowing humans to move rapidly on foot. It is also defined as a gait in which at regular points during the running cycle both feet are off the ground, in contrast to walking where one foot is always in contact with the ground. The benefits of running include improved vascular fitness, reduced cholesterol, strenghthening of the immune system and an improved self esteem and emotional state.

Research also states that running can also have psychological benefits, as many runners in the sport report feeling an elated, euphoric state, often referred to as a “runnner’s high”. Running is frequently recommended as therapy for people with clinical depression and people coping with addiction.

This explains why when I’m in a funk my first thought is to grab my running gear. But what is happening chemically in my body to produce this runner’s high?

Current research states that the body produces cannabinoids, lipids, that action resembles those of the active ingredient of marijuana…so that explains it (lol). This lipids suppress pain, inhibits swelling and inflammation, dilates the blood vessels and makes breathing easier. So the addiction is due to this powerful chemical that is naturally produces by the body.

Running increases your metabolism which explains why i raid the refrigerator after every run. Another fact about running it helps you to maintain and also lose weight.

So i know you are asking yourself why don’t I run? Well its never to late to be apart of this movement and if you dont want to run you can walk, the point is to keep your body moving and you will be rewarded with the release of a natural chemical that will keep you happy!!
