What Are the Treatment Methods for Dystonia in Children?

It is always distressing to see a child suffering from a disease. However, it is much more painful if any kid experiences uncontrolled movement of muscles. Such movements can make simple actions like walking, writing, feeding, or talking challenging. It is dystonia.

Dystonia is a neuromuscular movement disorder characterized by muscle contractions leading to repetitive movements and awkward posture. The condition can affect one body part or several muscle groups at once. There is no single treatment that cures dystonia in children. 

However, thanks to new diagnostic techniques and dystonia treatment methods, many children receive successful treatment nowadays. This article will discuss various treatment methods for dystonia in childhood and show why continuous treatment is crucial for children with this disease.

What Is Dystonia In Children?

Dystonia is a neurological disorder resulting from improper brain-muscle communication. As opposed to coordinated muscle activities, the brain transmits faulty commands, resulting in involuntary muscle contractions.

Dystonia can affect 

• The neck region
• Arms or hands
• Legs
• Face
• Vocal cords
• The whole body

The symptoms usually worsen when engaging in voluntary muscle movements, being under pressure or stress, or feeling extremely emotional. Dystonia can either present mild symptoms or lead to serious disabilities in some children.

Causes of childhood dystonia

Knowing the underlying cause is important in choosing the right treatment method. If parents or guardians also become aware of the root cause, they can confidently adapt the advised treatment option. Some significant ones are

Genetic Dystonia

A significant number of children with dystonia have this condition because of genetic mutations. Usually, dystonia appears in early childhood and progresses with time.

Dyskinetic Cerebral Palsy

Many children with dystonia have dyskinetic cerebral palsy because they have brain damage acquired either before, during or soon after birth.

Brain Damage

The reason for dystonia is also brain injuries, strokes, oxygen deficiency to the brain or infection of the brain. All of these cause damage to centers responsible for controlling movement.

Metabolic Diseases

There are rare cases when dystonia is caused by metabolic diseases which prevent the brain from functioning normally.

Neurodegenerative Disorders

Sometimes dystonia is accompanied by neurodegenerative disorders where certain brain cells are damaged gradually.

Major Symptoms 

Variations in symptoms appear depending on the body part affected by dystonia. The general ones are

• Abnormal bodily movements
• Awkward body postures
• Cramps
• Repetitive involuntary movements
• Problems in walking
• Handwriting difficulties
• Speech problems
• Difficulties swallowing
• Tremor
• Stiffness
• Pain from constant contraction of the muscles

Treatment options for dystonia in children

Treatment aims at alleviating symptoms, improving motor function, decreasing pain and increasing the independence of the child. Most patients need multiple therapy types, rather than a single treatment method. The possible options are

Medication

Different types of medication can decrease the contractions of muscles that happen involuntarily.

Some examples are as follows:

• Anticholinergic drugs
• Baclofen
• Benzodiazepine drugs
• Levodopa, which is used to treat certain types of dystonia
• Muscle relaxants
• Usually, the dose is increased gradually depending on how the child reacts to the drug.

Botulinum Toxin Injections

The injections are very effective for focal dystonia, where specific muscles are affected. It temporarily helps relax overactive muscles because it blocks nerve signals.

Advantages are:

• Reduced muscle spasms
• Improved posture
• Decreased pain
• Making daily activities easier

The effect lasts from three to four months.

Physical Therapy

In the long-term management of the condition, physical therapy is critical. Expert opinion is a must before application because the child’s age, intensity of disease and affected part are detrimental in this regard.

Notable outcomes could be

• Enhanced muscle strength
• Ensuring joint mobility
• Preventing muscle stiffness
• Improving balance
• Preventing contractures

Occupational Therapy

An occupational therapist can help a child accomplish activities of daily living more independently.

This can include the following:

• Handwriting
• Dressing
• Eating
• Hygiene
• Classroom participation

Speech and Language Therapy

Children with dystonia of the muscles of the face, throat or tongue can experience problems with communication or swallowing. Early treatment can make a big difference in a child’s quality of life.

Speech therapists work on:

• Communication
• Improving speech clarity
• Ensuring safe swallowing
• Feeding methods

Deep Brain Stimulation (DBS)

When medicines do not provide enough relief for severe dystonia in children, deep brain stimulation may be considered as an effective treatment option. DBS surgery involves placing small electrodes in specific areas of the brain that help control movement. 

These electrodes deliver gentle electrical signals to help regulate abnormal brain activity, which may reduce involuntary muscle contractions and improve movement and control.

Intrathecal Baclofen Therapy

Certain types of severe generalized dystonia are successfully treated by intrathecal baclofen therapy. Surgeons surgically implant a small pump in the skin in order to administer baclofen intrathecally.

The result of this treatment will be better control of symptoms and fewer side effects in comparison with oral drug use.

Long-Term Care of Children With Dystonia

Effective long-term management is much more than medications and surgical treatment. The main goal of long-term care of children with dystonia is to help them achieve their full physical, psychological, and social development. It comprises

Routine Medical Checkups

Children need routine checkups since their symptoms may change as they develop. Routine visits to doctors enable them to:

• Change medications
• Evaluate the progress of the disease
• Detect any side effects
• Recommend further treatment

Multidisciplinary Care

In order to achieve optimal results, a multidisciplinary team approach is always a wise strategy. A collaborative effort will ensure holistic care suited to the changing needs of the child.

Care teams can comprise:

• Pediatric neurologists
• Neurosurgeons
• Physical therapists
• Occupational therapists
• Speech therapists
• Rehabilitation specialists
• Psychologists
• Dieticians

Emotional and Psychological Support

A chronic movement disorder condition may impact the psychological state of the child. Children could suffer from anxiety and social exclusion. Counseling, behavior modification therapy, and group support services can be helpful to address such problems.

Home Care

Home care may include:

• Encouragement of exercise plan
• Watching symptoms
• Medication compliance
• Prevention of falls
• Emotional assistance
• Promoting independence if possible

Can People With Dystonia Lead Normal Lives?

A large number of dystonic children lead successful and happy lives with proper treatment and assistance. The outcome of dystonia depends upon the underlying condition, the severity of the symptoms, and when the treatment starts. 

There have been significant advances in treatment, drugs, and surgery which have improved the outlook for many patients considerably. Indeed, some children need lifetime help. However, proper treatment makes it possible for them to go to school, interact socially, gain independence, and live happy lives.

Conclusion

Finally, dystonia in children is a complicated neurological disorder which affects movements, postures and overall functioning of a child. Fortunately, modern techniques of treatment give a chance to improve symptoms and achieve more favorable results. Drugs, botulinum toxin, various therapies and advanced surgeries like deep brain stimulation are used to treat the condition.

Yet, proper long-term treatment is no less important. It presupposes the cooperation of healthcare providers, parents, schools and therapists. With timely diagnosis, appropriate treatment and assistance, many children with dystonia can cope with difficulties, utilize their potential and lead a fulfilling life.
