Muscular Dystrophy – A Silent Killer 

Welcome readers to our today’s blog! Just imagine having a disease that gradually weakens the muscles that you rely on for standing, moving, and even breathing. That is what Muscular Dystrophy is. It’s one of the rarest of mysteries—a disease many have heard of, but very few really know. It is not just a medical term but a daily struggle for many people and families around the world.

This health condition is more than just statistics; it’s about real people suffering from challenges most of us can’t even imagine. But, Why does it happen? Can Muscular Dystrophy be treated? These are questions that remain, waiting for answers.

In this blog, we will unwrap the mystery of Muscular Dystrophy, highlighting what it is, how it affects lives, and the hope science is working hard to bring. 

Let’s start the journey together and understand this rare condition because awareness is the first step to compassion.

What is Muscular Dystrophy?

Muscular dystrophy (MD) is a class of inherited muscular disorders characterized by progressive weakness due to degeneration of the muscle body. They primarily run in the family, as some people may acquire them from their parents. 

The primary feature of this rare disease is the progressive loss in mass and function of the muscle because the body would not be making enough proteins to sustain muscle in a normal state.

There are various types of Muscular Dystrophy, each involving different muscles and causing different symptoms. Patients with MD may face difficulties in simple daily activities such as walking, lifting objects, or even breathing as the disease advances. 

Patients with this disease also have difficulty moving their hands or feet over time. They can only sit and usually have some muscle strength on the upper body side.

Types of Muscular Dystrophy:

Okay, readers, as now we are familiar with the term Muscular Dystrophy or MD! Now, let’s talk about the various types of this rare disease:-

Types of Muscular Dystrophy

MD is a group of different genetic conditions, and they all make your muscles get weaker over time. It’s like your muscles are slowly losing their power. Here are some of the popular types of MD:

1. Duchenne Muscular Dystrophy (DMD):

Duchenne Muscular Dystrophy mostly happens to boys, and it usually starts showing up when they are kids. The starting age of its sufferers is around 3 to 5 years old. 

Boys with DMD start having trouble with their muscles, and they might have difficulty running or playing like other kids. As they get older, the weakness spreads around their bodies, which can make it very hard for them to walk, move hands, and get around. 

2. Becker Muscular Dystrophy (BMD):

BMD is similar to DMD, but it’s not as strong and doesn’t get worse quickly. Usually, the symptoms don’t start up until they reach their teen years, or sometimes even later when they become adults. People with BMD might have muscle weakness, but it’s generally not as bad as it is with DMD.

3. Myotonic Dystrophy:

This type of MS can happen to both boys and girls, and it can start at any age. What’s unique about it is that it causes your muscles to get stuck in a contraction, so it’s hard to relax them after using them. 

Think about how hard it is to open your fist after squeezing it tight. People who have myotonic dystrophy might also have heart issues, problems with their eyes, and other health issues.

4. Limb-Girdle Muscular Dystrophy:

In this type of muscular dystrophy, the muscles around your hips and shoulders are the first ones to feel the weakness. 

Then, the weakness can spread to other parts of the body as it gets older. Both boys and girls can have this, and it can start at any point in life. 

5. Facioscapulohumeral Muscular Dystrophy:

This type usually starts when you are a teenager, like 18-19 years of age. It starts with the muscles in your face, shoulders, and upper arms. 

You might find it hard to smile, close your eyes properly, or even lift your arms. We can’t even imagine how frustrating it must be for people suffering from it.

6. Congenital Muscular Dystrophy:

This kind of MS is present from the time a baby is born or starts very soon after. Babies with this type of muscular dystrophy have weak muscles very early on, and they also have issues with their joints.

It’s good to know that each of these kinds of MDs is different, and they all get worse in different ways, but they all have one major thing in common: muscle weakness. 

Causes of Muscular Dystrophy:

Every time we discuss this illness, everyone has a question in their mind: “Is muscular dystrophy genetic?” and its answer is “Yes.” Muscular Dystrophy, or MD, happens because of changes in our bodies instruction manuals, like when a page gets ripped in an important book. 

These changes, called genetic mutations, mess with how our muscles work. These mutations stop our bodies from making the special building blocks, called proteins, that keep our muscles strong and healthy. Let’s break it down:-

1. Inherited from Family:

Most of the time, MD is passed down from parents. It’s like getting a special characteristic, like having blue eyes, but in this case, it’s a gene that can cause muscle weakness. If a parent has a faulty gene for MD, they can pass it on to their kids. This passing down can happen in a few different ways:

• X-linked recessive: Imagine a special gene on the X chromosome, like a secret code. In Duchenne and Becker, MD, this faulty gene hangs out on the X chromosome. Because boys only have one X, they are more likely to be affected if they have this faulty gene. It is like a game of chance, unfortunately.
• Autosomal recessive: This time, both mom and dad have a faulty gene and accidentally pass it on. It affects both boys and girls equally. It’s like they both got a piece of the puzzle and gave it to their child.
• Autosomal dominant: In this case, just one parent has the faulty gene, and they pass it on to their child. This causes things like Myotonic Dystrophy. It is like when the secret code gets passed down from one person to another.

2. Brand New Changes:

Sometimes, Muscular Dystrophy happens because of a spontaneous mutation. It’s not passed down, but like a new change that just appears in the genes when a baby is made. It’s like a surprise puzzle piece that doesn’t come from the family set.

3. Missing Special Proteins:

Certain types of MD are caused by the lack of special proteins. It is like when you are missing an ingredient in a cake, and then your cake will turn out differently than expected. 

For instance, Duchenne and Becker MD happen because the body can’t make enough dystrophin protein. This protein is super needed to keep our muscles strong and sturdy. Other types of MD have to do with the lack of other important proteins that play many roles in our muscle’s strength.

To sum it all up, muscular dystrophy happens because of a gene problem that can be inherited or new. These changes in genes cause our body not to make the correct proteins needed for healthy muscles. 

When people are missing these proteins, it leads to different kinds of muscle issues. This is why MD might be different for different people.

Diagnosis of Muscular Dystrophy:

Diagnosing Muscular Dystrophy (MD) involves several steps to identify the type and extent of the condition. Let’s talk about each of them in detail:-

• Physical Check-up: Doctors will give you a physical check-up. They will look at your muscles, how well you move, and your reflexes. They will also ask about your family’s health to see if anyone else has had similar muscle problems.
• Blood Test: Doctors take a little of your blood to check for a special enzyme called creatine kinase (CK). If there is a lot of it in your blood, it could mean your muscles are a little hurt, which can make them suspicious that you might have an MD.
• Genes Testing: A special test looks at your genes, which are like the instruction book for your body. This tells doctors exactly what kind of MD you have and helps them figure out the best way to help you.
• EMG (Electromyography): A test called EMG uses a tiny needle to check how your muscles react to electrical signals. This test helps doctors see how healthy your muscles and nerves are.
• Muscle Biopsy: Sometimes, doctors take a small piece of your muscle to look at under a microscope. This helps them see what’s happening on the inside and if it’s specific to MD.
• Taking Pictures: Imagine doctors taking pictures of your muscles with a special camera. This helps them see if your muscles have changed and how the MD is moving along.

Treatment Options for Muscular Dystrophy:

Muscular dystrophy can really change a person’s life, but there are ways to help patients feel better, move more easily, and enjoy life more. 

There is not an actual proven cure for MD yet, but mixing different approaches like therapies, medicines, and support can make a big difference for people and their families.

Physical Therapy and Exercise

• Stretching and Moving: Doing stretches and moving your joints helps keep them flexible so they don’t get stuck. Regular stretches can also make you stand taller and feel more comfortable.
• Easy Exercise: Simple things like moving hands and rounding your feet are great for keeping your muscles strong, helping you move, and keeping you healthy overall. It’s always smart to ask your doctor what exercises are best for you.

Massage Therapy

How can a massage help with muscular dystrophy? Gentle massage helps your blood move better, loosens up stiff muscles, and makes sore muscles feel better. It also helps you relax, which is super important for people dealing with this rare illness.

Medical Treatments

• Corticosteroids Medicines like prednisone and deflazacort can make muscles stronger and slow down the disease by 10-12%. But, using them for a long time can cause side effects like gaining weight and weaker bones.

Special Medicines to help with Muscular Dystrophy approved by FDA:

• Eteplirsen (Exondys 51): This drug was approved back in 2016 for some people with a type of MD called Duchenne muscular dystrophy (DMD).
• Golodirsen (Vyondys 53): This drug was authorized in 2019 for people with DMD who have certain gene problems.
• Heart Helpers: If MD affects your heart, certain medicines can help it work better.

Supportive Devices

• Braces: This device can stretch and support muscles, which can stop muscles from getting too tight.
• Moving Helpers: Items like canes, walkers, and wheelchairs can help people stay independent and move around.
• Breathing Support: When breathing muscles get weaker, ventilators help you breathe in enough air.

Alternative Therapies

• Ayurvedic Panchakarma: These are detox treatments that might help calm down swelling and make sufferers feel better all around.
• Acupuncture and Yoga: These can go along with other treatments and help you relax and improve how your blood movements.

Around 1 in 5,000 people around the world have muscular dystrophy. But with new research and treatments that are coming out, there is lots of hope for better days ahead!

Conclusion on the Topic:

Muscular dystrophy is hard to live with, but you have hope backed up by changing therapies and determination. The condition is a mystery in many respects, but therapies such as ROM exercises, massage, and modern pharmacology offer relief and betterment of life as we know it. 

Muscular dystrophy is a humbling reminder about the power of humanity and the steadfast drive to cure ourselves by our families, caregivers & medical researchers. Although there is no cure yet, every bit of treatment step and innovation would be next to less.

It is the science of Muscular dystrophy… but that is only half of what we are trained as doctors to know… Empathy, Awareness, and Hope. We can work together to call attention to research and support so those affected are able to live fuller, more self-sufficient lives.

Every moment counts in transforming struggle into strength and turning fear of uncertainty into hope.
