Dystonia
Have you ever witnessed or experienced involuntary muscle contractions in your child that cause twisting, repetitive movements, or abnormal postures?
This could be a sign of dystonia, a neurological movement disorder that can affect children. Dr Arif Khan is dedicated to helping patients and their families understand and manage neurological conditions like dystonia.
This comprehensive guide covers dystonia symptoms, meaning, causes, and treatment options. It focuses on dystonia in babies and children, including which children are at risk and available treatments.
What is dystonia? Unpacking dystonia meaning
Let’s begin by understanding the meaning of dystonia. Dystonia is a neurological condition marked by ongoing or occasional muscle contractions that lead to abnormal postures or repetitive, twisting movements.
These movements can be painful and affect any body part, including the limbs, trunk, neck, eyelids, face, and vocal cords.
The underlying issue in dystonia lies in the brain’s basal ganglia, an area responsible for regulating movement. It’s believed that a disruption in the communication within the basal ganglia leads to involuntary muscle contractions.
Recognising the signs: Dystonia symptoms
The dystonia symptoms can vary widely depending on the type of dystonia and the part of the body affected. Some common symptoms include:
Involuntary muscle contractions: These can range from mild twitches to severe, sustained spasms.
Twisting movements: Affected body parts may twist into unusual postures.
Repetitive movements: These movements can be jerky or tremulous.
Abnormal postures: Holding a limb or the neck in an unusual position.
Pain: Muscle contractions can be painful, sometimes significantly so.
Tremors: Shaking movements may occur.
Speech difficulties (Dysarthria): If dystonia affects the muscles involved in speech.
Swallowing difficulties (Dysphagia): If dystonia affects the muscles involved in swallowing.
Symptoms may begin gradually or appear suddenly. Some symptoms may be triggered by actions or movements (action-induced dystonia).
Understanding Paediatric Dystonia: Dystonia in Children
Dystonia in children, also known as paediatric dystonia, encompasses a range of dystonic disorders that manifest in childhood. The symptoms can be similar to those seen in adults, but can significantly impact a child’s development and daily activities. Typical presentations of dystonia in children include:
Focal dystonias: Affecting a specific body part, such as the writer’s cramp or cervical dystonia (torticollis).
Generalised dystonia: Involving the majority or entirety of the body.
Segmental dystonia: Affecting two or more contiguous body parts.
Symptoms might initially be subtle and progress over time. Children with dystonia may experience difficulties with walking, fine motor skills, and participation in sports or other activities.
Unravelling the causes: What causes dystonia?
The question of “What causes dystonia?” is complex. The exact reason behind the condition is frequently unknown. However, dystonia can also be the result of:
- Genetic mutations: Researchers have identified multiple genes linked to various types of dystonia.
- Brain injury: Trauma, stroke, or lack of oxygen to the brain can lead to secondary dystonia.
- Certain medical conditions: Such as Wilson’s disease or cerebral palsy.
- Medications: In rare cases, certain medications can trigger dystonic reactions.
In paediatric dystonia, genetic factors are often more commonly identified compared to adult-onset dystonia.
Identifying risk factors: Which children are at risk for dystonia?
Answering “Which children are at risk for dystonia?” involves considering several factors:
Family history: Children with a family history of dystonia are at a higher risk of inheriting genetic forms of the disorder.
Brain injury: Children who have experienced brain trauma, stroke, or complications during birth that led to brain damage are at increased risk.
Certain neurological conditions: Children with conditions like cerebral palsy or genetic metabolic disorders may be more susceptible to developing dystonia.It’s important to remember that even with these risk factors, many children will not develop dystonia.

Treatment for Dystonia in Childhood
The “Treatment for dystonia in childhood” is tailored to the individual child’s symptoms, the type of dystonia, and its severity. A multidisciplinary approach involving neurologists, physical therapists, occupational therapists, and sometimes speech therapists is often necessary.
Dystonia in babies. Treatment options may include:
- Physical Therapy
- Occupational Therapy
- Speech Therapy
- Behavioural Strategies (e.g., relaxation techniques)
- Adaptive Equipment and Devices
- Oral Medications
- Botulinum Neurotoxin Injections
- Deep Brain Stimulation (DBS) Surgery
Oral Medications
Commonly used medications include:
- Baclofen
- Trihexyphenidyl
- Levodopa
- Diazepam
Note: These medications should only be taken under the supervision of a qualified doctor. Self-medication can be harmful and may lead to serious side effects. Always follow your healthcare provider’s guidance.
Dopa-Responsive Dystonia (DRD)
Dopa-responsive dystonia represents a group of genetically inherited disorders frequently misdiagnosed as cerebral palsy.
- Clinical recommendation: A trial of levodopa is widely recommended for children presenting with dystonia.
- Rationale: DRD often responds dramatically to levodopa therapy, and even children with other forms of dystonia may experience benefits.
Common challenges and support needs
Children with dystonia often experience a range of motor and non-motor issues that impact their daily lives:
- Pain and discomfort
- Difficulty with daily tasks and hand function
- Seating and mobility challenges
- Sleep disturbances
- Communication difficulties
- Children with inherited forms of dystonia may be more prone to developing anxiety and depression.
Comprehensive care approach
While managing movement symptoms is central to treatment, addressing non-motor issues is crucial for improving overall quality of life. A comprehensive treatment plan should include:
- Mental health support.
- Pain management strategies.
- Assistive technologies
- Family and caregiver education.
- Ongoing interdisciplinary evaluations.
