Dystonia

Involuntary muscle contractions twisting the body into abnormal postures. Painful, treatable, and often mistaken for something psychological.

What it is

Dystonia causes sustained or intermittent muscle contractions that pull the body into abnormal postures or repetitive movements. Around 100,000 people in the UK are affected.

It can be focal, affecting one area such as the neck, eyelids, hand or voice, or generalised. Cervical dystonia, affecting the neck, is the commonest form in adults.

It is a neurological condition. People with dystonia are frequently told it is stress or anxiety, sometimes for years, and that misattribution is one of the most consistent complaints in patient surveys.

A distinctive feature worth knowing: the sensory trick, or geste antagoniste, where lightly touching the affected part reduces the spasm. Somebody resting a finger on their cheek to hold their head straight is not fidgeting.

Signs you might notice

Involuntary turning, tilting or pulling of the neck. Excessive blinking or forced eye closure.

Cramping of the hand during a specific task, such as writing or playing an instrument, while other uses are fine.

A strained, strangled or breathy voice in laryngeal dystonia.

Pain, which affects the majority and is under-treated.

Symptoms worse with stress and fatigue, better with the sensory trick, and often absent during sleep.

How it can affect day-to-day life

Pain is the biggest daily problem in cervical dystonia and is frequently not asked about.

Driving, reading and working at a screen all become difficult, and the visible movements attract attention and assumptions.

Depression and social anxiety are common, and they follow the condition rather than causing it.

Botulinum toxin injections are the main treatment for focal dystonia and are given every twelve weeks or so, with a predictable wearing-off period that shapes the whole quarter.

Supporting someone well

Take the pain seriously and ask about it directly.

Learn the sensory trick and do not discourage it.

Plan around the botulinum toxin cycle: the weeks before the next injection are harder, and appointments and demanding activities are better placed early in it.

Do not attribute it to stress. Stress worsens dystonia exactly as it worsens tremor, and that is not the same as causing it.

Ask for referral to a specialist movement disorder clinic rather than accepting general management.

Physiotherapy alongside injections improves outcomes and is often not offered.

Where to get help

Ask a GP for referral to a neurologist with an interest in movement disorders.

Dystonia UK run a helpline and hold a list of specialist centres.

Sudden onset dystonia after starting a new medication, particularly an antipsychotic or anti-sickness drug, needs urgent medical attention.
