There are two main types of movement disorders- dystonia and dyskinesia. While they may share some common symptoms, the two disorders are caused by different mechanisms and require other treatments.
In this article, we will take a closer look at each disorder and explore the differences between them.
What’s the difference between dyskinesia and dystonia?
Dystonia and dyskinesia are both types of movement disorders, but they are caused by different mechanisms and require other treatments.
Dystonia is characterized by involuntary muscle contractions that can cause twisting or repetitive movements.
Dyskinesia, on the other hand, refers to unwanted or uncontrollable movements that may be slow or fast and can be involuntary or voluntary.
Both dystonia and dyskinesia can cause pain and fatigue and interfere with movement and daily activities.
Dystonia and dyskinesia may both be treated with medications, Botox injections, or surgery.
However, the treatment approach will depend on the specific type of movement disorder that is being treated.

Types of dyskinesia and dystonia
There are several different types of dystonia and dyskinesia, each with its own characteristic symptoms and causes.
Dystonia
There are several different types of dystonia, each with its own distinct symptoms and causes.
Cervical dystonia
Cervical dystonia, also known as torticollis, is a type of dystonia that affects the neck muscles.
This condition causes involuntary twisting and repetitive movements of the head and neck, which can cause pain, fatigue, and difficulties with movement and daily activities.
The exact causes of cervical dystonia are not entirely clear, but it is believed to be the result of a combination of genetic and environmental factors.
Writer’s cramp
Writer’s cramp is another type of dystonia that can affect people who use their hands and fingers extensively for writing, playing an instrument, or other similar activities.
This condition causes involuntary muscle contractions in the hand and can interfere with fine motor control and coordination.
Dystonia may also be triggered by certain medical conditions, such as Parkinson’s disease, stroke, or brain injuries.
Dyskinesia
There are several different types of dyskinesia, each with its own distinct symptoms and causes.
Parkinson’s dyskinesia
Parkinson’s disease is a neurodegenerative disorder that can cause a wide range of movement abnormalities.
One of these is dyskinesia, which refers to uncontrolled and often repetitive movements that can be slow or fast, deep or shallow, and may occur in a variety of different body parts.
Huntington’s chorea
Huntington’s chorea is a genetic disorder that causes changes in brain function, which can lead to a wide range of movement disorders.
One of these is dyskinesia, which causes involuntary and uncontrollable movements.
Dyskinesia may also be caused by certain medications or drugs, such as antipsychotic medications or amphetamines.
What causes dyskinesia and dystonia?
There is no single definitive cause of dystonia or dyskinesia. However, both disorders are believed to be the result of a combination of genetic and environmental factors.
For example, some types of dystonia may be caused by specific gene mutations, while others may be more likely to occur in people with a family history of the condition.
Environmental factors may also play a role in the development of dystonia and dyskinesia, including certain medical conditions, physical injuries or trauma, infections, and exposure to toxins or other harmful substances.
In addition, some medications and drugs have been associated with the development of these disorders.
For example, some antipsychotic medications have been linked to the development of Parkinson’s dyskinesia.
Treatment for dystonia and dyskinesia
There are a variety of different treatment options that can be used to manage symptoms of dystonia and dyskinesia. These may include:
- Medications
- Botox injections
- Surgery
For example, cervical dystonia may be treated with drugs that help to relax the neck muscles and relieve spasms, such as botulinum toxin injections or anticholinergic medications.
Similarly, the writer’s cramp may be treated with Botox injections or physical therapy to help with fine motor control.
In addition, dyskinesia may be treated with medications that help to regulate the levels of dopamine in the brain, such as levodopa or anticholinergic drugs.
Other treatments may include deep brain stimulation surgery or rehabilitation therapies.

Summary
Overall, dystonia and dyskinesia are complex disorders that can affect people in a variety of different ways.
While there is no single cause or treatment for these conditions, there are a number of different options available to help manage symptoms and improve quality of life.
If you are experiencing any symptoms of dystonia or dyskinesia, it is important to speak with your doctor to discuss possible treatment options.
