What is dystonia?

Reviewed July 2026 by Karlo J. Lizarraga, MD, MS, FAAN, FANA

Definition: Dystonia is a condition that causes muscles to move when you don’t want them to. These movements can cause your affected body parts to hold strange positions, twist, or shake.

Dystonic movements and postures are often:

  • Patterned and twisting
  • Sustained, repetitive, or intermittent (possibly including shaky or jerky movements)
  • Started or made worse by intentional movement

Dystonia can also be associated with non-movement symptoms such as depression, anxiety, and pain.

Symptoms can vary widely from person to person. Dystonia can affect a single body area (focal dystonia) or multiple areas. Cervical dystonia, which is focal dystonia of the neck, is the most common type of dystonia.

Dystonia often starts slowly and it may worsen over time. Learning about symptoms, diagnosis, and treatment options can help you have more informed conversations with your care team.

What are the symptoms of dystonia?

Dystonia symptoms include:

  • Repetitive or abnormal movements or postures
  • Muscle tightening or spasms that may last for a while or come and go
  • Movements that can vary in severity and pattern

Symptoms differ depending on the body part involved and the type of dystonia.

What are the causes and risk factors of dystonia?

The exact cause of dystonia is often unknown.

Dystonia may be:

  • Genetic, caused by genetic changes that can be inherited in families.
  • Acquired, due to factors like brain injury (from trauma, infections, tumors, or other lesions), exposure to certain medications or toxins, and other neurological conditions.
  • Unknown, meaning no clear cause is identified.
  • Multifactorial, meaning several causes may contribute.

How is dystonia diagnosed?

There is no single test to diagnose dystonia. Your doctor will review your medical history, evaluate your symptoms and movement patterns, and do a neurological examination. Depending on your history and examination findings, your doctor may suggest genetic testing, medication trials, a brain MRI, or other tests.

Diagnosis may take time because:

  • There are no widely available objective diagnostic markers
  • Symptoms vary from person to person
  • The condition can share symptoms with other movement disorders

What treatments are available for dystonia?

There is currently no cure for dystonia, but treatments can help manage symptoms and improve daily life for many people. Doctors and therapists can work together to help you manage your dystonia.

Management approaches for movement symptoms may include:

  • Botulinum toxin injections, which must be done by a trained doctor and may need to be repeated every three to four months
  • Medications
  • Physical or speech therapy
  • Surgery, such as deep brain stimulation or other procedures

It’s also important to identify and manage non-movement symptoms. Some people with dystonia also experience depression, anxiety, and pain.

Treatments often provide temporary relief, not a cure. Effectiveness varies depending on what type of dystonia you have. More research is needed to develop treatments that target underlying causes.

Frequently asked questions

What parts of the body can dystonia affect?

Dystonia can affect one body area (focal), nearby areas (segmental), several separate areas (multifocal), or the whole body (generalized).

Is dystonia rare?

Dystonia is considered a rare disorder, affecting a relatively small number of people. However, support, diagnosis, and treatment options are available.

Is dystonia genetic or inherited?

Some forms of dystonia are linked to genetic factors, while others occur without a known cause or involve multiple possible causes or predisposing factors.

Does dystonia get worse over time?

The course of dystonia varies. Some forms remain stable, and others may change or involve more of the body over time. This depends on the underlying type and cause of the condition.

When should you talk with a doctor about dystonia?

Consider talking with a neurologist or other health care professional if you notice repeated abnormal movements, spasms, twisting movements, unusual postures, or symptoms that interfere with daily activities.
