The Signs and Symptoms of Multiple Sclerosis (MS)

By Molly Perski

Multiple Sclerosis (MS) is an autoimmune disorder of the central nervous system in which the body attacks and breaks down the protective covering of our nerves called myelin sheaths. Myelin sheaths surround the nerves in order to protect and insulate them so that they can fire properly and ensure their signals reach their destination. An easy way to think about it is to compare them to the plastic coating that covers  electrical wires! When that plastic coating is damaged and the wire is exposed, we can receive dangerous electric shocks as the electric current diverts from its intended destination. The same happens with the electric signals that are sent through our nervous system. We rely on these electric signals to transmit information from our brain to the rest of our body. When the myelin sheaths that protect the nerves are damaged, the electric signals in our central nervous system (CNS) can become disrupted which causes disconnect between what our brain wants our body to do and how it actually responds.

People experience the onset and progression of their condition in different ways, at different times, and at different levels of severity. To explain this, doctors have identified 4 main types of MS: primary progressive, secondary progressive, progressive relapsing, and relapsing-remitting. Most people (about 85%) have relapsing-remitting MS which begins presenting symptoms as early as their 20’s. Once this starts, they  experience attacks of symptoms called relapses. The severity, frequency, and length of the relapses vary for each person. These are then followed by periods of recovery called remission that can last for weeks, months, or years. Eventually, most people with this type of MS move into the secondary progressive phase where the onset and worsening of their symptoms becomes more steady and their remission periods grow shorter and shorter. This shift typically happens later in  life (around 10—20 years after diagnosis) and symptoms become harder to treat. Unlike the secondary progressive phase that gradually decreases periods of remission as symptoms increase, the primary progressive phase lacks defined periods of relapsing and remission and gradually worsens over time. People with this type of MS are typically older when they receive their diagnosis (around 40) and it’s much harder to treat. Only about 10% of MS cases fall into this category.  The fourth type of MS, primary progressive, is harder to diagnose. It, too, lacks periods of relapse and remission and progressively gets worse over time. Most people with this type of MS (only about 10-15% of all MS cases) are diagnosed later in life and typically discover they have it due to problems with walking, weakness in the legs, or trouble balancing.

Signs and symptoms of MS can vary greatly from person to person, depending on the location of the affected nerve fibers in their CNS. Some of the most common symptoms people with MS experience include numbness or weakness in their torso or limbs (typically occurs on one side of the body at a time), electric-shock sensations (primarily in the neck), tremors, lack of coordination, unsteady gait (walking), vision problems, slurred speech, fatigue, dizziness, tingling in different parts of the body, and issues with bowel/bladder function.

While researchers still don’t know what causes MS, they are finding more and more ways to effectively treat the symptoms. They have been able to identify several risk factors that increase a persons chances at developing the condition. Some of these include age (typically diagnosed between 20—40 years old), sex (women are more likely to develop it then men), race (white people of northern European descent pose the highest risk), climate (MS is more common in countries with temperate climates), low levels of vitamin D, smoking, family history of MS, certain infections (a variety of viruses have been linked with MS development), or having another existing autoimmune disease.

GROUP EXERCISE CLASSES ARE RETURNING!!!!

After 10 long months, Burcham is finally able to start bringing group programming back to the community! The first exercise class to return will be the ever popular Fit and Functional class! For those of you who haven’t had the opportunity to attend this class in the past, Fit and Functional is an intro level exercise course that focuses on building strength and endurance. All exercises are performed seated which makes this group a viable option for everyone who wants to participate!

We are also slowly starting to reopen the Wellness Center (Rm. 208) and will be offering Open Gym hours   for each floor. During this time, residents may come and utilize any of the exercise equipment in the gym and will have the opportunity to consult with a member of the fitness team regarding exercise questions, tips, and regimens!

Whether you regularly exercise or if this is a whole new ball game for you, everyone can take something valuable away from participating. We hope to see you there!

Per the CDC and LCS guidelines, groups will be returning slowly at limited capacity  (no more than 10 residents per group) and will be first come first serve.

Masks MUST be worn over the nose and mouth for the entire duration of the class, no exceptions.

Each floor will have a designated day that programming is offered for them (pending quarantine status). Please refer to the schedule below for details.

The Science Behind Vaccines and Your Immune System

By Molly Perski

One of the most important discoveries we’ve made in the field of medicine is the vaccine! Vaccines are used to help prepare our immune systems to fight off harmful or deadly pathogens that may potentially infect us. It might surprise you to learn that the very first vaccine was actually developed all the way back in 1796 by Edward Jenner to protect people against smallpox! This early method involved taking fluid from a blister of someone infected with cow pox and inoculating it into another person’s skin (there is actually evidence to suggest that people were using similar versions of this type of    treatment as early as 200 BC!) Vaccines didn’t start becoming routinely recommended to the general public until the early 1900’s, but the process was streamlined in the 1940s so that large-scale vaccine production could occur in order to start mass disease control efforts.

The practice of healing and medicine dates back thousands of years, each culture having their own unique way of curing ailments and  procuring remedies.

With the new covid-19 vaccination becoming available, many  people have found themselves with handfuls of unanswered questions about how it works, why it’s effective, and if there are risks to  taking it. In order to understand how a vaccine works, we need to  understand our immune system. Simply put, your immune system protects your body from pathogens and foreign invaders like bacteria, viruses, fungi, and toxins. If one these manages to get inside your body, your immune system springs into action to fight it off before it can spread and make you sick or cause an infection.

There are 2 main components to our immune system. The first is our innate immune system which is the immune system we are born with, and the second is our adaptive immune system which your body develops as it’s exposed to different microbes. It senses when foreign microbes or pathogens enter our body and responds by producing cells called antibodies that protect you by fighting off that specific invader. After your first exposure to the illness, the antibodies stick around and help your body to recognize and fight it off  quickly if it ever returns. This is the basis for how vaccines work in our body! They help us develop immunity by imitating an infection from a pathogen so our body can produce the proper antibodies and learn to fight off the real thing when the time comes!

Now that we have a more basic understanding of how our immune system works and how vaccines prep them to ward off diseases,  let’s talk more specifically about the new COVID-19 vaccine. As many of us have heard, this new COVID vaccine is what’s known as an mRNA vaccine. While this is one of the first vaccines to utilize this technique, scientists have been studying mRNA vaccines for decades! This type of vaccine is of key interest because it can be developed in a laboratory using readily available materials. This allows the production process to be standardized and scaled up more efficiently and speeds up the development of producing the vaccine over the traditional methods. Let’s take a closer look at what mRNA is and how this type of vaccine works.

Most of us know that DNA is what codes for our genetic information, but what is RNA? RNA is the intermediate step in the body’s process of taking DNA and making proteins. DNA is comprised of  4 nucleotides (adenine, thymine, cytosine, guanine) that are each paired with a 5-carbon sugar and a phosphate molecule and then arranged into different patterns to create our genetic code! RNA is very similar to DNA, but there are 2 main differences between the two. The first is that DNA has a “deoxyribose” sugar while RNA has a “ribose” sugar. The second has to do with its nucleotides. RNA uses 3 of the 4 same nucleotides as DNA (adenine, guanine, and cytosine) but has a unique 4th nucleotide called “uracil” tha replaces “thymine”. RNA is created through the process of “transcription” which takes a strand of DNA and uses it as a template to make a new strand of RNA using the RNA nucleotides. This RNA strand then acts as a messenger (that’s what the “m” in mRNA stands for!) and takes this genetic template it obtained from the DNA over to these subunits within our cells called “ribosomes” that use it to make protein! These proteins are then integrated into the cell or sent out into the body. Now that we understand this important concept, we can look more closely at how mRNA vaccines like the new COVID-19 vaccine work.

The COVID-19 virus is covered in proteins (known as “spike proteins”) that help the virus to latch on to and penetrate a healthy cell so it can replicate, and they signal to our immune system that the virus is present which triggers an immune response. This is why the new COVID-19 vaccine is specifically targeting these spike proteins! The way the mRNA COVID-19 vaccine works is it provides our body with the RNA template that is used by the virus to make the spike protein (NOTE: the spike protein is not what makes you sick!) so that our immune system can become familiar with them and produce the antibodies needed to fight off the real virus down the line (this is our adaptive immune system at work!) It’s important to note that a vaccine is not the same thing as a cure—it’s job is to prevent diseases, not to treat them. If you’ve had the vaccine, it doesn’t mean that you’re unable to contract the disease it’s protecting against, it just makes it a lot less likely that you will. When enough people are vaccinated and are less likely to contract a disease, the population develops a “heard immunity” which works to keep everyone safe and prevent mass spreading.

After you receive a vaccine, it takes time for our immune system to familiarize itself with it and to create the proper immune response (antibodies) necessary to fight it off again in the future. Some vaccines, like the COVID-19 vaccine, require additional injections to maximize its effectiveness. Because of this, it’s possible for people who are newly vaccinated to still catch the virus since their bodies haven’t built up the proper immune response yet (NOTE: this doesn’t mean the vaccine caused them to become sick).

Until we establish a better heard immunity, it’s important that we continue to do our part by washing our hands, wearing  our masks, and practicing social distancing.
