Do you sometimes feel a strange stiffness in your neck, a pain, and your head is pulled to one side? Or do the muscles in your neck suddenly twitch, causing you to shake your head uncontrollably? These may not just be a simple neck sprain. Today we are going to talk about a neurological condition related to the neck that you may not have heard of, but can affect some people. This is what doctors call `(Cervical Dystonia)`.
What is Cervical Dystonia?
Simply put, cervical dystonia is a neurological condition in which the muscles in the neck contract uncontrollably due to a problem in our brain and nervous system. It's like the muscles in the neck are getting a little naughty and dancing to their own tune.
When these muscles contract, they become tight instead of relaxing. This can even change your posture. Your head and neck may start to move in an abnormal way, as if they were suddenly spasming or jerking. This can be a very painful experience and can interfere with your ability to perform daily activities.
Cervical dystonia is one of a larger group of conditions called ``Focal Dystonia.`` Focal Dystonia refers to conditions that cause muscle spasms in just one part of the body. Sometimes your doctor may also call it ``Spasmodic Torticollis.`` Although it is called by two or three names, it is the same condition.
Are there main types of cervical dystonia?
Yes, two main types can be identified. These two types are distinguished based on the reason for this:
1. Primary cervical dystonia: In this case , the exact cause of the disease is not known. It is a condition that simply occurs.
2. Secondary cervical dystonia: In this case, a cause can be identified. This means that it can be caused by another medical condition, a side effect of a medication, or an accident.
How common is this condition?
Cervical dystonia is one of the most common diseases in the ``Focal Dystonia`` category. It is estimated that nearly 60,000 people in the United States alone suffer from this condition. There may be such patients in Sri Lanka as well, and perhaps the statistics may be lower due to underdiagnosis.
What are the symptoms of cervical dystonia?
This condition causes movements that you cannot control. The main symptoms include:
- Muscle spasms: The muscles in the neck suddenly become tight, like rocks, and cannot be relaxed. Sometimes the muscles may feel like they are twitching or moving.
- Tremors: Uncontrollable shaking of parts of the body, such as the hands and legs. This shaking can also occur in the neck area.
These uncontrolled movements can cause changes in your posture. Posture is the way you hold your body when you are standing or sitting. Cervical dystonia can cause these changes in posture:
- Rotating your head: You may have your head turned to one side without even realizing it.
- Tilting the head forward, backward, or to the side: As if the head is tilted to one side.
- Bending the neck and head forward, backward, or to the sides: It becomes difficult to keep the neck straight.
These movements can also cause pain in the shoulders and neck, which can be accompanied by inflammation . Some people also experience headaches . Imagine how difficult it can be to do your daily work with something like this.
Why does cervical dystonia occur?
In fact, doctors still don't know the exact cause of cervical dystonia in every patient. But research suggests that it is caused by a dysfunction in a part of our brain called the ``Basal Ganglia'' . This part of the ``Basal Ganglia'' controls the movement of our muscles. When there is a problem there, the wrong signals are sent to the muscles in the neck, causing them to function improperly.
Secondary cervical dystonia can be caused by the following factors:
- As a side effect of some psychiatric medications .
- Due to severe injuries to the brain (Traumatic brain injury) .
- With other neurological conditions, such as Parkinson's disease .
- Genetic mutations in genes called `GNAL`, `THAP1`, `CIZ1` or `ANO3`. These are a bit more complicated, but they are possible.
Who is at higher risk of developing this disease?
Although this condition can develop at any age, some people are at higher risk:
- If someone in your family has had this disease before (there may be a genetic link).
- If you are taking medications called `(Dopamine antagonists)` or `(Antipsychotics)`.
- If you have had a brain injury.
This disease is most common among women and people between the ages of 30 and 60. But that doesn't mean that others can't get it.
What are the possible complications of cervical dystonia?
These symptoms can have a big impact on your daily life. It can even make it difficult to do some tasks. Pain, tremors, and muscle twitching can make it difficult to move your neck, jaw, arms, and torso properly. It can also make things like talking, swallowing, and physical coordination difficult.
In some severe cases, you may find yourself unable to do even simple tasks that you used to be able to do easily, such as combing your hair or brushing your teeth. This can be really distressing.
If left untreated, this condition can cause pain and muscle spasms (dystonia) in other parts of the body besides the neck . Therefore, it is very important to seek medical advice immediately if you have symptoms.
How is this disease diagnosed?
A doctor will examine you and ask about your symptoms to determine whether you have this disease. They will also ask about your medical history and family medical history . This means finding out if anyone in your family has had this disease.
Not everyone usually needs tests like an MRI scan or an electromyography (which measures the electrical activity of muscle fibers). However, the doctor may order these tests only if they suspect spinal cord compression or nerve damage .
What are the treatments for cervical dystonia?
There are different treatments for this. Not all treatments work for everyone. You may need to try several treatments to find what works best for you.
There are mainly these types of treatments:
- Botulinum toxin injections: These are injections that are given to the affected muscles of the neck.
- Oral medications: Medications given to reduce pain and ease muscle spasms.
- Physical therapy: Strengthen the muscles in the neck and improve movement through exercises and other methods.
- Deep brain stimulation surgery: This is a somewhat complicated surgery that is not necessary for everyone and is performed in special cases.
Some people also find that holding their chin or wearing a neck brace or cervical collar helps relieve their symptoms . These are called sensory tricks.
The most important thing is to work with your doctor to find the treatment that's right for you.
How does botulinum toxin treatment work?
Many people have heard of the name `(Botox®)`. It is a brand name for `(Botulinum toxin serotype A)`. Similarly, `(Botulinum toxin type B)` is also used to treat cervical dystonia.
What this `(Botulinum toxin) does is weaken the function of the affected neck muscles (dystonic neck muscles). Then, those muscles stop contracting unnecessarily.
The doctor injects this medicine into the appropriate muscles in your neck. It can take about a week to see the effects of the medicine. However, the effect of this medicine lasts for about two to three months. After that time, symptoms may reappear. Therefore, you will have to get repeated injections to control the symptoms.
Side effects of this vaccine may include:
- Difficulty swallowing
- Pain at the injection site
- Feeling of weakness in the neck
These things don't happen to everyone, but it's good to know that they can happen.
What other medications are given for cervical dystonia?
The following types are commonly used as oral medications:
- `Dopaminergic agents` (e.g. `Levodopa`)
- Anticholinergic agents (eg Benztropine, Trihexyphenidyl)
- `Baclofen`
- `Clonazepam`
These medications can also cause side effects such as memory problems and fatigue . Therefore, it is important to discuss all of these with your doctor and choose the treatment that is best for you.
What will the condition of cervical dystonia be like? What is the outlook?
Cervical dystonia is a lifelong condition. However, it does not affect your lifespan. Sometimes symptoms may gradually worsen over time, or they may plateau.
The best part is, with proper treatment, you and your doctor can manage these symptoms, so you can get back to doing the things you love without any difficulty.
Can cervical dystonia be completely cured with `(Botox)`?
No. There is no complete cure for cervical dystonia yet. Botulinum toxin (Botox) can only temporarily control the symptoms, it is not a cure.
Is there a way to prevent cervical dystonia?
Unfortunately, there is currently no known way to prevent the development of this disease.
When should I see a doctor?
See a doctor if you notice any of these things:
- If you feel like the flesh in your neck is twitching or tightening.
- If you have already been diagnosed with cervical dystonia and the treatment is causing side effects or if the symptoms are getting worse.
It is very important to seek medical advice quickly at times like this.
What should I ask my doctor?
When you go to see the doctor, you can ask questions like:
- If someone in my family has had this disease, am I at risk of developing it too?
- What treatment do you recommend for me?
- Are there any side effects of the treatment?
- Will I need surgery?
In addition to these questions, ask your doctor any doubts or questions you may have.
Finally, things to remember (Take-Home Message)
Cervical dystonia can be a really uncomfortable and painful condition. Because the muscles in your neck can't relax, your head moves involuntarily. This can make it difficult to do things you used to enjoy, and it can make it difficult to perform everyday tasks.
But remember, you are not alone. There are treatments for this. Your doctor can help you find the best treatment for your symptoms. Then you can get well again. So if you have symptoms, don't be afraid to see a doctor.
I hope this information is useful to you. Stay healthy!
