Cervical dystonia is a neurological condition that affects the muscles in your neck, causing involuntary spasms and abnormal head movements. In this article, we will explain cervical dystonia in simple terms, covering various aspects of the condition, including types, causes, symptoms, diagnostic tests, treatments, drugs, and surgery.
Types of Cervical Dystonia:
Cervical dystonia can manifest in different ways, depending on which muscles are affected:
- Torticollis: This is the most common type of cervical dystonia, where your head twists to one side, causing your chin to point to the opposite shoulder.
- Retrocollis: In retrocollis, your head tilts backward involuntarily.
- Laterocollis: Laterocollis makes your head lean to one side.
- Anterocollis: This type results in your head tilting forward.
- Mixed Dystonia: Sometimes, people may experience a combination of the above types, known as mixed dystonia.
Causes of Cervical Dystonia:
Cervical dystonia’s exact cause remains unknown, but there are several factors that may contribute to its development:
- Genetics: Some cases have a genetic component, meaning it can run in families.

- Botulinum Toxin Trial: A therapeutic trial of botulinum toxin injections may be conducted to confirm the diagnosis.
- Functional Assessments: Evaluations of how the condition affects your daily life and functioning.
- Psychological Assessment: Assessing emotional well-being, as cervical dystonia can impact mental health.
- Voice and Speech Assessment: If voice changes are present, a speech therapist may be consulted.
- Swallowing Evaluation: If swallowing difficulties are a concern, a swallow study may be done.
- Neurological Evaluation: A comprehensive neurological assessment to rule out other disorders.
- Pain Assessment: Evaluation of pain levels and its impact on daily activities.
- Quality of Life Surveys: Questionnaires to assess the impact of cervical dystonia on your overall well-being.
- Eye Examinations: To check for abnormal eye movements or vision problems.
- Therapeutic Response: Improvement in symptoms after botulinum toxin injections can help confirm the diagnosis.
- X-Rays: Occasionally, X-rays may be used to assess bone and joint changes.
- Electroencephalogram (EEG): In some cases, an EEG may be performed to evaluate brain wave activity.
- Neuropsychological Testing: Assessments to evaluate cognitive functioning and emotional health.
Treatments for Cervical Dystonia:
Cervical dystonia is a chronic condition, but several treatments can help manage its symptoms effectively:
