Dystonia

Dystonia symptoms vary from person to person and often start gradually before becoming more noticeable over time. Common features include:

• Involuntary muscle spasms or cramps, often brought on by movement or specific tasks such as writing or playing an instrument.
• Abnormal twisting or pulling movements that cause awkward or fixed postures, for example the head turning to one side (cervical dystonia) or the eyelids clamping shut (blepharospasm).
• Tremor or shaking in the affected body part, sometimes described as a “dystonic tremor”.
• Pain, muscle tiredness and a feeling of tightness or “pulling” in the neck, arms, legs or face.
• Symptoms that worsen with stress, fatigue or anxiety and improve with rest, relaxation or sleep.

If dystonia affects several body areas, you may also notice problems with balance, walking, hand coordination, speech or swallowing.

Dystonia happens when the deep structures of the brain that help control movement do not send signals in the usual way, leading to overactive, uncoordinated muscle contractions. In many people there is no clear cause, but in others it can be linked to genetics, another neurological condition or an external trigger.

Possible causes and risk factors include:

• Genetic changes that may run in families, especially when symptoms start in childhood or teenage years.
• Damage to the brain from stroke, head injury, infections, lack of oxygen, or conditions such as Wilson disease or Parkinson’s disease.
• Certain medications, particularly some antipsychotics and anti‑sickness drugs, which can cause drug‑induced dystonia or related movement disorders.
• Other movement disorders where dystonia occurs alongside tremor or Parkinsonism.

Your consultant at The London Clinic will explore these possibilities carefully, as understanding the underlying cause helps guide the most appropriate treatment.

For most people, dystonia cannot be fully prevented because the exact cause is unknown or genetic. However, some steps can lower the risk of certain secondary or drug‑induced forms.

• Reviewing long‑term medicines with your doctor, particularly antipsychotics and anti‑sickness drugs, and reporting any new abnormal movements promptly.
• Protecting against head injury where possible, for example by using appropriate safety equipment during higher‑risk activities.
• Seeking timely assessment for conditions such as Wilson disease or Parkinson’s disease if suggested by your GP or neurologist, so that treatment can begin early and complications may be reduced.

Your team at The London Clinic can also advise on lifestyle measures, physiotherapy and stress‑management techniques that may help you live more comfortably with dystonia and reduce everyday symptom triggers.
