Do you also have difficulty walking or doing things? Do you feel like you're losing your balance? Shall we talk about this (Spinocerebellar Ataxia)?

Do you sometimes feel like your legs are getting tangled when you walk? Or do you feel like you can't even hold a cup in your hand properly? Maybe you even get slurred words when you speak. If these things happen not just once or twice, but several times at once, it's not something we should ignore. Today we are going to talk about one possible cause of this, which is a condition called `Spinocerebellar Ataxia` (we will call it `SCA`).

What is `Spinocerebellar Ataxia (SCA)`? Let's understand it simply.

Ataxia is, simply put, a condition in which you gradually lose your ability to coordinate your body's movements . It's something that affects your nervous system and gets worse over time. Imagine losing your ability to move your arms and legs, walk, or hold something. There are many types of ataxia, each with its own causes and symptoms.

Spinocerebellar Ataxia (SCA) is another type of ataxia, and it is a genetic condition . It mainly affects your cerebellum . The cerebellum is a very important part of your brain. It controls things like your walking, grasping, and maintaining your balance. Sometimes, SCA can also affect your spinal cord .

Because this is hereditary, the symptoms gradually increase over time. You won't see a big difference right away. This mainly affects your:

• For the function of the eyes.
• For hand functions (for example, writing, holding a cup, eating).
• Loss of leg function and ability to walk (loss of balance).
• The way you speak (the words get tangled).

What is said has the most impact.

How many types of `SCA` are there?

Currently, doctors and scientists have identified more than 40 types of SCA. This number is likely to increase in the future, as research continues. Doctors call these types of SCA by numbers. For example, Spinocerebellar Ataxia type 1, type 2, and so on.

The causes and symptoms of all these types of SCA are largely similar. So you might be wondering why they are numbered. The numbers are given in the order in which the genetic changes associated with each SCA type were discovered. Simply put, SCA1 is the first type to be discovered and linked to a chromosomal problem that is passed down through generations. SCA2 is the second type discovered. That's how they are named.

The most common type of SCA is Spinocerebellar Ataxia type 3 (SCA type 3) . It is also known as Machado-Joseph disease .

So, how common is this `SCA`?

Actually, this condition called `SCA` is very rare . That means it is not a disease that affects everyone. According to statistics, this disease occurs in one (1) out of every hundred thousand people, or at most five (5) people. Therefore, it is normal not to hear about it often.

Why do we get this `SCA`? What is the cause?

The main cause of SCA is a genetic mutation . This means that there is a defect in the genes you inherit from your parents. Experts have linked these specific gene defects to many types of SCA. However, not all types of SCA are caused by the same gene mutation, but by variations in different genes.

Some types of SCA are caused by a specific part of your DNA (the part that stores our genetic information) being repeated an abnormal number of times. This is called a trinucleotide repeat expansion in medical terms. It's a bit complicated, but in simple terms, it's like a certain part of a gene is copied too many times.

There are two main ways in which this `SCA` condition is inherited:

1. Autosomal Dominant Inheritance:

• This is how SCA is often inherited.
• What happens in this case is that even if you inherit this mutated gene from only one parent , your mother or your father, you can still develop this condition.
• This means that if a person with `SCA` has a child, there is a 50% chance that that child will inherit this mutated gene. Think of it like the chance that a coin will land heads. This chance is the same for every child.

2. Autosomal Recessive Inheritance:

• There are also types of `SCA` that are inherited this way, but they are a little less common.
• In this case, for a person to develop this condition, they must inherit this abnormal gene from both their mother and father.
• In most cases, these parents do not show symptoms. They may simply be carriers of the gene. They only have one copy of the gene defect, so they do not develop the disease.

What are the symptoms of SCA?

Symptoms of SCA usually begin to appear after the age of 18. However, some types of SCA can begin earlier, and some can begin later. It is not something that comes on suddenly, but gradually, over a period of years, the symptoms become more severe.

Imagine, when you go to make tea and hold the kettle, your hand shakes and the tea leaves fall, or when you walk down the street, you just slip to the side and fall. It feels very difficult when you go up and down stairs. If these things happen often, it is important to take care of it.

The most common symptoms of SCA are:

• Involuntary eye movements: It's like you can't keep your eyes in one place, or they're jerking from side to side rapidly.
• Poor hand-eye coordination: For example, difficulty holding a glass of water properly, difficulty buttoning a shirt, or difficulty writing clearly.
• Problems with balance and coordination: Walking can feel like you're going to stumble or fall easily. It can also be difficult to stand straight.
• Slurred speech: Slurred speech , where words cannot be pronounced properly, making speech unclear. As if tongue-tied.
• Trouble processing and remembering information / learning disabilities: Difficulty learning new things, quickly forgetting things that have been said, and difficulty concentrating.
• Uncoordinated walking: Walking as if drunk, as if unable to keep your feet straight, as if trying to walk with your feet spread wide apart.

These symptoms can vary from person to person, and their severity can also vary depending on the type of SCA.

How do doctors diagnose SCA?

If you have these symptoms, when you see a doctor, if they suspect you have SCA, they will test you for the following to make a diagnosis:

• Your family history: You will be asked if anyone in your family has had these symptoms before, or if there is anyone with this condition, SCA. This information is very important because it runs in families.
• Your personal medical history: They will ask about other illnesses you have had before, the medications you take, and your lifestyle.
• A complete physical exam: This will include tests specifically related to your nervous system. They will check your balance, gait, strength in your arms and legs, reflexes, eye movement, and speech.
• They will carefully examine you to see if you have any symptoms related to SCA.

After these things, further tests can be done to confirm the disease:

• Genetic testing: This is the main way to know for sure if you have SCA. A sample of your blood (or possibly a saliva sample) is taken and tested for the gene that is responsible for SCA. Many types of SCA can be detected with this genetic test.
• However, there are some types of SCA for which a specific genetic mutation has not yet been identified. So in such cases, it is difficult to confirm with genetic testing alone.
• In such cases, doctors may do special scans to check for any abnormalities in your brain. The most common is an MRI scan (magnetic resonance imaging) . This can look for any shrinkage (atrophy) in your cerebellum. Sometimes a CT scan (computerized tomography) may also be done.

Also, people who think they may have inherited the gene mutation because someone in their family has SCA can get this genetic test. This can be very important for those who are planning to start a family, that is, for those who are planning to have children, to make decisions. Also, when a child is about to be born, that is, during pregnancy, it is possible to check whether the baby has this condition (prenatal testing) .

Is there a cure for this `SCA`? Can it be cured?

This is what everyone wants to know. Unfortunately, there is currently no cure for `Spinocerebellar Ataxia (SCA).` You may feel sad when you hear this, and that is normal.

However, that doesn't mean that nothing can be done. The main goals of treating SCA are:

• Reducing symptoms.
• Improving the quality of life.
• Helping you to work independently for as long as possible.

The following can be done as treatments for `Spinocerebellar Ataxia`:

• Physical therapy: This is very important. A physical therapist will teach you how to exercise properly, strengthen your muscles, improve your balance, and improve your walking style.
• Occupational therapy: Helps you create your environment to help you perform everyday tasks (e.g., eating, dressing, writing) more easily, and teaches you techniques to help you do so.
• Speech therapy: If speech is slurred or there is difficulty swallowing words, a speech therapist can help.
• Assistive devices: As the disease progresses and walking becomes difficult, you may need to use crutches, a walker, or a wheelchair. These can help you do things on your own.
• Medications to reduce some symptoms: Doctors may prescribe medications to help with things like tremors, stiffness, muscle twitching, insomnia, and depression. However, these medications do not cure SCA, they only control the symptoms.

Doctors and researchers are still trying to find new treatments and ways to help people with SCA, manage it, and find new ways to treat it. So don't give up hope.

Is there a way to prevent the development of `SCA`?

This is a question that many people ask. To be honest, there is currently no proven method to prevent SCA. Because it is mainly caused by genetic factors, it cannot be stopped by what we eat or drink or by the exercise we do.

Some families, after genetic testing confirms that they have this mutation in their family, may decide not to have children. This is the only sure way to prevent the condition from being passed on to the next generation. This is a very sensitive, personal decision. It is very important to talk to a genetic counselor before making such a decision.

What can someone with SCA expect in the future?

When it comes to the future of someone with SCA, it's important to note that it varies greatly from person to person . It depends on a number of factors, including the type of SCA you have, its severity, and the age at which symptoms began.

Sadly, in many cases of SCA, the disease gradually worsens, leading to premature death.

How quickly the condition progresses also varies depending on the type and severity of SCA. Therefore, genetic testing can help to determine not only what the disease is, but also what the future holds.

Many people may need a wheelchair 10 to 15 years after the first symptoms begin. It is common for people with SCA to eventually need help with everyday tasks, such as bathing, dressing, and preparing meals.

What else should I ask my doctor about SCA?

If you have `Spinocerebellar Ataxia (SCA),` or if someone in your family has it, it is very important to ask your doctor these questions:

• What type of `SCA` do I have exactly? (e.g. `SCA1, SCA2, SCA3`?)
• What functions in my body does this type of `SCA` most affect?
• What kind of specialists (e.g. neurologist, physical therapist) should I see to manage this condition?
• How often should I come for medical checkups? What special tests should I have?
• What treatments are available to me right now? What are the benefits?
• Could this condition shorten my lifespan? (This is a difficult question to ask, but it's important to know.)
• Is it possible for my children to inherit this condition? If so, how likely is it?
• Is it a good idea to have other members of my family (e.g. siblings, children) get genetic testing?
• What kind of support groups do you know of that can help me cope with this situation and stay mentally strong? Are there any such groups in Sri Lanka?

Don't be afraid to ask these questions. The better you understand your situation, the easier it will be for you to live with it.

What should I do to live well with SCA?

It's normal to feel a lot of questions, fear, sadness, and anger when you find out you have SCA. It's the same for everyone. You're not alone. The following may help you cope with this difficult situation and manage it a little better:

• Ask for help and support from people you trust and are close to (family, friends) . Don't struggle with these things alone. Share your feelings with them.
• Be an active participant in your treatment . Go to your doctor's appointments, follow his or her instructions carefully, ask any questions you have, and do things like physical therapy.
• Consider talking to a mental health counselor or psychiatrist . They can help you deal with this situation, learn how to cope, and become mentally stronger.
• Don't bottle up your feelings, don't ignore them . Cry if you're sad, express it if you're angry (but in a way that doesn't bother others).
• If possible, join a support group where you can meet others who are facing the same challenges as you. This will help you feel less alone and you can also learn from the experiences of others.
• Have realistic expectations . Understand what you can and can't do. You may have to give up some things, so be prepared for that.
• Instead of feeling sad about not being able to do the things you used to be able to do, focus on the things you can still do . Try to be happy with even the little things.
• Eat a good, nutritious diet, exercise as much as possible, and get enough sleep. These things are good for your overall health.

Remember, SCA is just one part of your life. Don't let it define you completely. You still have a loving family, friends, and things you can still do.

So, what should we take home from this story?

Spinocerebellar Ataxia (SCA) is a genetic condition that affects the brain and sometimes the spinal cord. It mainly affects the body's balance and coordination of movements. The condition gradually worsens over time.

The most important thing is:

• There is currently no specific cure for SCA. However, there are treatments (such as physical therapy, assistive devices, and medication) to control symptoms and make life easier.
• If you have symptoms related to `SCA`, seek medical advice immediately . Getting a diagnosis early helps you start treatment.
• Since this is a genetic condition, it is important for the family to be aware of this and, if necessary, undergo genetic counseling and testing .
• Living with SCA is a challenge, but with proper medical advice, family support, and mental strength, this journey is possible.

If you have any further questions about this, don't hesitate to talk to your doctor.
