Have you ever heard, or have you heard from someone in your family or friend, about a very strange, rare disease that only affects people? Sometimes it takes a long time to find out what this disease is. So today we are going to talk about such rare diseases . It is very important to know about these, because you never know when we will need this knowledge.
What is a rare disease?
Simply put, a rare disease is a disease that affects only a very small number of people in society. Now, look, in a country like America, a disease that affects less than two hundred thousand people is considered a rare disease. In England, a disease that affects less than one in 2,000 people. According to the World Health Organization (WHO), diseases that affect less than 65 out of 100,000 people fall into this category. So you see, the definition of this varies a little from country to country.
So far, researchers have discovered more than 7,000 such rare diseases! Imagine, all of these diseases affect more than 300 million people worldwide, most of whom are young children. There are people with such diseases in Sri Lanka too, but they are not talked about much.
Imagine if you or someone you know had a rare disease like this. How challenging would that be?
- It can take years to figure out exactly what the illness is. Sometimes, even after going to one doctor after another and undergoing one test after another, the disease cannot be identified.
- The symptoms of these diseases can be similar to those of other common diseases, so it's not immediately obvious that this is a rare disease.
- Symptoms can make it difficult to perform daily tasks, hold a job, or do household chores. For some, just getting through the day can be a big challenge.
- Many rare diseases still have no effective treatments.
- Living with an illness like this can be a huge financial burden for families. It can be difficult to afford the cost of medication and treatment.
- Both the patient and those caring for him or her feel great mental and physical fatigue.
But science is advancing day by day. Scientists who research diseases like this are constantly trying to find the causes and develop new treatments. So don't worry.
Is there a difference between orphan diseases and rare diseases?
Many people use the terms "orphan disease" and "rare disease" interchangeably. But there is a slight difference. Orphan diseases are diseases that researchers have not done much research on, or at all (this can include rare diseases). This is often due to the high cost of research.
But now the situation is changing a bit. Governments and various organizations around the world have started to allocate money for research into ``orphan drugs`` to find cures for such "orphan diseases."
What are some rare diseases?
As we've said before, there are thousands of rare diseases. Some of them you've probably heard of. Others are not as well known. Here are a few examples:
- Acromegaly
- Alice in Wonderland syndrome
- Amyotrophic lateral sclerosis (ALS)
- Aplastic anemia
- Cystic fibrosis
- Duchenne muscular dystrophy
- Ehlers-Danlos syndrome
- Fabry disease
- Gaucher disease
- Huntington's disease
- Mesothelioma
- Maple syrup urine disease
- Sickle cell disease
These names may sound a little strange, but all of these are rare conditions that affect people.
What are the causes of rare diseases?
There can be a variety of reasons for the occurrence of rare diseases. There are three main categories of causes:
1. Genetics: Changes in genes are the primary cause of many rare diseases. These genetic changes can be inherited from your parents (germline mutation), or they can occur randomly in your body without any family members having them (somatic mutation).
2. Germs/Microbes: Infections caused by some microbes can be very rare. For example, diseases like tuberculosis are rare in some countries but common in others.
3. Toxins: Some chemicals can have a negative effect on the body and cause disease. For example, exposure to asbestos can cause mesothelioma, a rare lung cancer.
In addition, there may be other reasons:
- Not getting enough of a certain vitamin or mineral (Nutritional deficiency).
- Accidents `(Injuries)`.
- Unexpected effects during treatment for another disease.
Sometimes, there are cases where no cause can be found for these rare diseases.
What are the symptoms of these diseases?
The symptoms of rare diseases are very different from each other. It varies from disease to disease. As mentioned earlier, sometimes these symptoms are very similar to the symptoms of other common diseases. This makes it difficult to accurately identify the disease. Some people may not show any symptoms at all in the early stages.
If you are experiencing body aches, constant fatigue, and can't figure out the cause, definitely see a doctor.
How are rare diseases diagnosed?
Identifying a rare disease is often challenging. There are several reasons for this:
- Symptoms similar to other diseases.
- Many diseases are so rare that even doctors don't see them very often, making it difficult to diagnose.
It can take years to find out exactly what's going on inside your body. Doctors will ask you about your symptoms and do tests, such as blood tests and imaging tests, to find out more. Doctors understand that this process can be stressful and frustrating. They will do everything they can to help you diagnose the condition, or refer you to specialists who have expertise in the area.
How do you find out if a baby has these diseases?
In countries like America, every newborn baby undergoes a series of special tests called ``Newborn screenings.'' These tests are used to detect certain diseases that are not visible at first glance, but may be present in the baby (e.g., sickle cell disease, cystic fibrosis). These ``Newborn screenings'' are a very important way to identify rare diseases in young babies. If the disease is detected early, treatment can be started for the baby as soon as possible. Some of these tests are also performed in Sri Lanka.
What are the treatments for rare diseases?
There are various possible treatments for rare diseases:
- Medications
- Nutritional supplements or changes to diet
- Occupational therapy
- Some procedures or surgeries
- Physical therapy
- Use of special medical devices
The goals of treatment also vary depending on the disease:
- Completely curing the disease (this is often difficult to do).
- Preventing the disease from getting worse.
- Controlling symptoms.
Sadly, many rare diseases still have no cure, but researchers are continuing to work to find treatments that could help millions of people.
You can ask your doctor about new experimental treatments (clinical trials) . These are carefully designed studies in which researchers test how well certain tests and treatments work. By joining one of these, you may be able to get the latest, most likely effective treatments for your condition.
Be wary of any "treatment" or "cure" you see on the Internet. If you come across one, show it to your doctor. He or she can tell you if it's right for you, if it's helpful, or if it's just a waste of money or if it's harmful to you. Some things may not help at all, and some may even harm you.
What does the future hold for someone with a rare disease?
Your future, or what the future holds, depends on several things:
- What is your specific medical condition ?
- How quickly the disease was diagnosed .
- What treatments are available ?
- What other health problems do you have?
Your doctors can tell you more about these things. Many people with rare diseases live happy, long lives. Unfortunately, some rare diseases can shorten a person's life span.
Remember, everyone is different. While you can learn a lot from talking to others who have the same condition as you, your own journey may be different. For example, don't be discouraged if a treatment that worked for someone else doesn't work for you. Your doctors will continue to work with you to find the best options for you.
Can rare diseases be prevented?
Because many rare diseases are caused by genetic factors, there is very little we can do to prevent them. If you or your partner have a rare disease and you are planning to have a child, it may be helpful to seek genetic counseling . The counselor can explain the chances that your baby will have the disease.
When do you need to see your doctor?
If you develop new symptoms or if your symptoms change for no apparent reason, see a doctor. If you've seen several doctors and they can't find a cause, you can ask for a referral to a medical center that specializes in diagnosing, treating, and researching rare diseases.
Important questions to ask your doctor
Here are some questions to help you learn more after receiving a diagnosis:
- How did I get into this situation?
- What treatments can I get? How are they done?
- What can you say about my future?
- Would you recommend participating in a clinical trial for a new experimental treatment?
- Is it a good idea to have genetic testing for my family as well?
- Can you connect me to patient support groups like this?
Where can I get information and support?
Living with a rare disease can be very lonely at times. It can be difficult to find other parents who understand your situation, especially if your child has been diagnosed with the disease. Talk to your doctor about how you can build a network of people and resources that you and your family can turn to for support. For example, there may be opportunities to join online patient support groups or clinical trials.
In Sri Lanka, some hospitals also have specialist doctors who help people with rare diseases. Also, some voluntary organizations provide support to such patients and their families. So do some research.
The most important things we need to remember
Living with a rare disease is not easy, but remember that you are not alone.
- Get the right information. Learn about your disease, its treatments, and the latest research.
- Connect with a good medical team. Find doctors and healthcare workers who understand you and support you.
- Join support groups. Talking to people who have had similar experiences as you is a great source of strength.
- Don't give up hope. Science is advancing, new treatments are coming.
We still know very little about many rare diseases. But researchers are discovering new things every day. So face this challenge with courage. Don't forget that there is someone who can help you, someone who will listen to you.
