Do you ever feel like things in your body are changing in ways you can't control? Sometimes it's like you lose your balance when you walk, or you feel dizzy when you stand up suddenly. These are things we sometimes don't pay much attention to, but they can also be symptoms of some rare neurological diseases. Today we're going to talk about one such condition that is a bit complicated, but it's very important to be aware of. That's Multiple System Atrophy (MSA) .
What exactly is Multiple System Atrophy (MSA)?
Simply put, Multiple System Atrophy (MSA) is a rare neurological disease in which parts of our brain gradually weaken, that is, deteriorate. Over time, the functions and abilities of our body controlled by these parts of the brain begin to deteriorate. This is actually a rather serious condition, because it is difficult to fully recover from it.
In the past, MSA was called by many different names. You may have heard of names like `Shy-Drager syndrome`, `Sporadic olivopontocerebellar atrophy`, `Striatonigral degeneration`. It was only later that doctors realized that all of these conditions had some common features. That's why they combined them all and gave them a new name, `Multiple System Atrophy` (MSA). The symptoms vary depending on which part of the brain is damaged. That's why each person experiences a different combination of symptoms.
There are two types of MSA, right? What are they?
Yes, to more clearly identify the condition of MSA, doctors have divided it into two main types, depending on the symptoms that appear:
1. MSA-C : The 'C' here stands for `cerebellar'. This type mainly affects your ability to coordinate your movements. That is, you lose your balance , which doctors also call `ataxia'. This is the main symptom of this type. At the same time, you may also see problems with the body's automatic control systems (`autonomic dysfunction`) and frequent falls.
2. MSA-P : The 'P' here stands for `parkinsonism'. In this type, symptoms similar to Parkinson's disease are seen. Although these Parkinson's symptoms are more prominent in the early stages, over time, problems with the autonomic nervous system and symptoms of `ataxia' may also appear.
Who is most affected by this MSA condition? How common is it?
MSA usually affects adults over the age of 30. Symptoms are most likely to appear between the ages of 50 and 59. It can affect anyone, regardless of gender.
But MSA is a very rare condition . Experts say that there are only 0.6 or 0.7 new cases per 100,000 people per year. The total number of cases is estimated to be between 3.4 and 4.9 per 100,000. So you can see how rare this is.
What happens to the body with MSA? Which parts of the brain are affected?
MSA is a progressive disease that affects different parts of the brain. Symptoms depend on the part of the brain that is affected. The main areas of the brain affected by MSA are:
- Basal ganglia : These are located right in the middle of the brain. They connect different parts of the brain and help them work together. It's like the brain's main control room .
- Brainstem : This is what controls many of the automatic processes in our body. That is, things that happen automatically without us thinking about them, for example, breathing, heart rate, and blood pressure. These are essential for survival.
- Cerebellum : This is located at the back of the head, at the base. It is mainly responsible for controlling movement and maintaining balance. It also works with other parts of the brain. Researchers are still learning about its full function, but some evidence suggests it is also involved in our emotions and decision-making.
So, when these parts of the brain are damaged, the functions that are controlled by those parts cannot be performed properly. For example, if the `Brainstem` is damaged, problems with automatic things like blood pressure can occur.
What are the symptoms of MSA? How do we recognize them?
Some symptoms of MSA are common to both types, and some are specific to each type. But one thing that is common to both types is autonomic dysfunction. Simply put, your body's automatic control systems go haywire.
Symptoms caused by problems with the autonomic nervous system:
- Orthostatic hypotension : This is when your blood pressure suddenly drops, causing dizziness , when you change position, for example, when you stand up suddenly from sitting.
- Inability to control urine (`urinary incontinence`) and inability to control stool (`fecal incontinence`).
- Sexual dysfunction, especially in men, is difficulty getting an erection (erectile dysfunction).
- Rapid eye movement (REM) sleep behavior disorder : Similar to Parkinson's disease, when you dream, you actually act out the things you did in your dreams. You may scream or flail your arms.
- Decreased sweating (anhidrosis).
- Vision problems.
- Dry mouth.
- Sleep apnea.
- Slow digestion and constipation.
Consider that many of these autonomic symptoms can appear months, even years, before motor symptoms appear. This occurs in between 20% and 75% of MSA patients.
Mental and emotional characteristics
About a third of people with MSA experience problems with their ability to think and concentrate. They also have difficulty controlling their emotions. This can lead to mental health problems such as:
- Anxiety.
- Depression.
- Emotional instability: That is, crying and laughing inappropriately.
- Panic attacks.
- Thoughts of harming or killing yourself.
Movement-related features
Characteristics of MSA-C (cerebellar type):
This type mainly involves `ataxia` (loss of balance). The `cerebellum` is a part of the brain that plays a major role in controlling muscle movements. So, when that coordination is lost, things like this can happen:
- Uncontrolled, chaotic movements of the limbs.
- Action tremor : This means that when you try to do something, the tremor in your limbs increases.
- Walking with unusually wide feet .
- Uncontrollable eye twitching (nystagmus).
Characteristics of MSA-P (Parkinsonism type):
This type of symptom often starts on one side of the body and then spreads to both sides. These symptoms usually look like this:
- Slow movements (bradykinesia), feeling as if the body is lifeless .
- Feeling of stiffness and stiffness in the body, resulting in a posture that seems to be leaning forward.
- Frequent stumbling while walking.
- Stuttering when speaking, unclear speech .
Why does this MSA occur? What is the reason?
The exact cause of MSA is not yet known , but experts suspect that it is related to a protein called `alpha-synuclein`, which can accumulate in various parts of our brain. This same protein is also suspected to be a major cause of Parkinson's disease.
Proteins are essential chemicals for our bodies to function. They help with many things, such as communicating between different systems in the body and transporting chemical compounds around. However, if these proteins accumulate in the wrong places, they can cause damage. Experts believe that this damage is what causes the brain tissue to gradually die in MSA.
Scientists are still researching why this `alpha-synuclein` protein accumulates in certain parts of the brain. They also suspect that certain genetic mutations may change the way some cells use this `alpha-synuclein`. There is also evidence that the MSA-C type runs in families. However, no such genetic link has yet been found for the MSA-P type.
The most important thing is that MSA is not a contagious disease . You cannot catch it from someone else, nor can you spread it to someone else.
How do you know for sure if you have MSA? What tests are done?
The only way to be 100% certain that someone has MSA is to examine their brain tissue after they die, because there is no way to accurately see if `alpha-synuclein` has accumulated in areas of the brain while someone is alive.
While someone is alive, doctors suspect MSA based on symptoms, medical history, family history, and whether or not they respond to certain treatments. Often, the first diagnosis is Parkinson's disease or another similar movement disorder, and the diagnosis is changed to MSA later when new symptoms develop or certain medications stop working.
There are several key features that can distinguish MSA from Parkinson's disease:
- MSA progresses rapidly : It takes years for someone with Parkinson's disease to develop problems with the autonomic nervous system. But in MSA, these problems can begin within a year.
- Some symptoms appear differently : Autonomic nervous system symptoms, in particular, are more severe in MSA. However, things like tremors may be less severe, or may be absent altogether. The way symptoms spread throughout the body may also vary.
- Treatments don't work : Levodopa is the main medication for Parkinson's disease. However, levodopa is less effective in MSA. This is often the main reason why doctors think it might be MSA and not Parkinson's.
What tests are being done for this?
There are very few tests that directly help diagnose MSA. Most tests are done to rule out other diseases and to gather more evidence to support the suspicion that it may be MSA. Some of these include:
- Magnetic resonance imaging (MRI) scan : This can sometimes show areas of the brain that have been damaged. This can help to make a more accurate diagnosis. It is also useful in identifying MSA-C, as it can show a cross-striped pattern in a part of the brain (the "hot cross bun" sign). However, this sign can also be seen in other diseases, so it is not enough to diagnose MSA on its own.
- Genetic testing : This can check for a genetic mutation that affects the way a person's body processes alpha-synuclein. These tests are more likely to identify genetic mutations associated with MSA-C among Japanese people.
- Skin biopsy : Some types of skin biopsy can detect signs of alpha-synuclein accumulation in nerve tissue. However, more research is needed to determine whether this is useful enough to be a standard part of the diagnostic process.
Your doctor will tell you about other tests that are appropriate and how they can help you. They will consider your health history, family history, and other factors to make the best decision for you.
Is there a treatment for MSA? Can it be cured?
There is currently no cure for MSA . Therefore, treatment is primarily aimed at controlling the symptoms for as long as possible. Treatment for MSA depends on many factors, including the patient's symptoms and their severity.
What medications or treatments are used?
There are many types of medications that can help control the symptoms of MSA. The type of medication you receive will depend on your symptoms and other factors. Your doctor is the best person to recommend the best medication for you, as they will be the most knowledgeable about your condition. They will also explain to you the possible side effects of the treatments.
Important: MSA is a condition that can only be diagnosed by a trained, qualified doctor. Therefore, do not attempt to diagnose or treat symptoms yourself without speaking to a doctor.
Is there a way to prevent MSA from developing?
Experts don't yet know what causes MSA or what factors contribute to it. Therefore, there is currently no way to prevent it or reduce the risk .
What kind of future can someone with MSA expect?
People with MSA usually first develop symptoms related to movement. This condition gradually worsens over time. About half of patients need help walking during this time. This means using a cane or walker. About five years after the onset of MSA, about 60% of patients need to use a wheelchair. Within six to eight years, at least half of patients are confined to bed.
As the disease progresses, additional procedures or interventions may be needed to maintain body functions and prevent dangerous complications. Some of these include:
- Tracheostomy to maintain breathing.
- Feeding through a tube (`Tube feeding` / `enteral nutrition`).
- Indwelling catheters or urostomy for urinary incontinence.
- Colostomy for bowel movement difficulties.
How long does MSA last?
MSA is a lifelong, permanent condition. The average life expectancy with the disease is six to ten years . In less severe cases, it can last up to 15 years. However, in more severe cases, the life expectancy can be much shorter. These severe cases usually include the following symptoms:
- Autonomic nervous system symptoms become severe before the onset of movement-related symptoms.
- Older age at diagnosis.
- Having movement symptoms that cause frequent falls.
What is the view on this situation?
The outlook for MSA is not very good. The symptoms of this condition gradually worsen, often interfering with the body's functions and leading to fatal complications. Complications that can lead to death include:
- Pneumonia.
- Urinary tract infections (UTIs) can cause sepsis (blood poisoning).
- Sudden death (often at night, due to disturbances in the way the brain controls breathing during sleep).
How do I take care of myself/my loved one? What should I be concerned about?
People with MSA have progressive symptoms. This means that once symptoms reach a certain level, they are no longer able to live independently. The condition can also eventually affect your ability to think, speak, and make decisions for yourself. Because of all of these factors, it is important to talk to your loved ones about your wishes for the future and to make a plan for your medical care if you are unable to make decisions .
When should you see a doctor?
Many of the early symptoms of MSA are things you should discuss with a doctor. These include:
- Sexual immorality.
- Orthostatic hypotension (persistent dizziness or fainting for no apparent reason).
- Sleep problems and sleep apnea (suffocating during sleep).
If a doctor diagnoses you with a movement disorder like Parkinson's disease, it's important to talk to them about any changes in your symptoms. Your doctor will schedule follow-up visits to monitor your condition and adjust your medication. You can talk about any changes you notice during these visits. It's common for people diagnosed with Parkinson's disease to change their diagnosis later, either when new symptoms develop or when levodopa stops working properly.
People with MSA often experience other symptoms, especially mental health problems. It is important to seek treatment for mental health problems related to MSA, as well as for physical symptoms. Your doctor can recommend treatment or refer you to a mental health specialist.
In summary (Take-Home Message)
Multiple System Atrophy (MSA) is a serious, ultimately fatal disease. Unfortunately, there is no direct cure or treatment for this condition yet.
