Quick answer
What is Dystonia?
Dystonia is a neurological movement disorder in which muscles contract involuntarily, causing repetitive twisting movements or sustained abnormal postures. It can affect one area — such as the neck (cervical dystonia), eyelids (causing forced blinking), hand (as in writer's cramp) or voice — or, less often, be more widespread.
- How it is treated: Treatment is tailored to the type and area affected and aims to reduce the abnormal movements and improve function and comfort.
- Self-care: Physiotherapy, learning "sensory tricks" that temporarily ease movements, managing stress (which can worsen symptoms), and support from patient organisations all help people live with dystonia.
- When to seek help: See a GP about persistent involuntary muscle spasms, twisting movements or abnormal postures, for referral to a neurologist.
What it is
Dystonia is a neurological movement disorder in which muscles contract involuntarily, causing repetitive twisting movements or sustained abnormal postures. It can affect one area — such as the neck (cervical dystonia), eyelids (causing forced blinking), hand (as in writer's cramp) or voice — or, less often, be more widespread. It may be uncomfortable or painful and can affect daily activities. Some forms are inherited or start in childhood, while others begin in adults with no clear cause or follow another condition or certain medicines. Diagnosis is clinical, sometimes with tests to look for an underlying cause.
How it is treated
Treatment is tailored to the type and area affected and aims to reduce the abnormal movements and improve function and comfort. For dystonia affecting one area, injections of botulinum toxin into the overactive muscles are often very effective, repeated periodically. Medicines that act on the nervous system help some people, and physiotherapy and specific "sensory tricks" can ease symptoms. For severe, widespread dystonia, deep brain stimulation (a surgical treatment) may be an option. Care is usually guided by a neurologist.

When to get help
When to see a doctor
See a GP about persistent involuntary muscle spasms, twisting movements or abnormal postures, for referral to a neurologist. Seek urgent care for a sudden, severe reaction with muscle spasms after starting a new medicine.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
