Muscle Dystonia
On this page, you will find everything you are looking for regarding muscle dystonia.
What is Muscle Dystonia?
Muscle dystonia is a term used to describe involuntary and sometimes painful muscle movements (spasms). It is a highly complex neurological movement disorder characterized by involuntary muscle contractions. It can affect children or elderly individuals of any age and occurs due to an abnormal dysfunction in the part of the brain responsible for movement.
- The types of muscle dystonia are identified based on which part of the body is affected:
- Hemidystonia affects the leg and arm on one side of the body.
- Multifocal dystonia affects two different parts of the body.
- Segmental dystonia affects two adjacent parts of the body.
- Generalized dystonia affects the entire body.
Focal dystonia concerns a specific area of the body.
What are the Symptoms of Muscle Dystonia?
- Muscle dystonia is sometimes misdiagnosed as strain or neck stiffness due to the difficulty in diagnosis and the similarity of its symptoms to other conditions. Dystonia initially arises after specific movements or tasks, but in advanced stages, symptoms may appear even at rest and may affect other muscles. Symptoms vary depending on the area of the body affected, such as:
- Mild facial spasms or difficulty chewing, suggesting jaw dystonia.
Hand spasms during writing or fatigue while walking or performing other manual activities, indicating limb dystonia.
- Muscle dystonia may affect the entire body or just a single part. Symptoms can manifest at any age, including:
- Uncontrollable muscle spasms.
Body parts twisting into unusual positions, such as tilting the neck to one side or inward rotation of the feet.
What are the Causes of Muscle Dystonia?
- It is believed that dystonia is caused by a malfunction in the part of the brain that controls movement, often with an unknown cause. However, in some cases, it may be due to:
- Genetics.
- Parkinson’s disease..
- Stroke..
- Cerebral palsy.
- Multiple sclerosis.
Side effects of certain medications.
What are the Diagnostic Methods?:
- The doctor takes the patient’s medical history and conducts a clinical examination. Additional procedures may be required as needed, such as:
- Conducting blood and urine tests.
Magnetic resonance imaging (MRI) of the brain to ensure there is no other problem causing the symptoms.
What are the Treatment Methods for Muscle Dystonia?
Treatment varies based on the underlying cause of the condition and may include the following:
Deep Brain Stimulation: A surgical procedure to implant electrodes in the brain, providing a mild electrical current to a brain area, helping alleviate symptoms. It is the most common and beneficial surgical treatment for dystonia.
- Medications: Depends on the cause of the dystonia and includes:
- – Direct injection of medication into the affected muscles, needing repeat procedures about three times daily. This prevents dystonia from reaching the muscles, making it a treatment for focal dystonia.
– Muscle relaxants taken as tablets or injections.
Physical and occupational therapy can also help alleviate symptoms and adapt to the condition, usually used for those showing symptoms due to a specific health condition or circumstance.
How Can Muscle Dystonia be Prevented?
It is not possible to prevent the onset of muscle dystonia, but genetic tests can reveal if a person’s genes carry a mutation that may cause dystonia.
What are the Complications of Muscle Dystonia?
Complications and side effects depend on several factors, including the treatments themselves and the location of the spasms. Permanent muscle deformities can occur, as well as tendon contractions.
When Should You See a Doctor?
Early signs of muscle dystonia are often mild and rare, linked to a specific activity. However, you should consult a doctor immediately if you notice involuntary muscle movements.
