When caring for a child with a complex health condition such as myasthenia gravis (MG), a strong support system is a cornerstone of care. When first receiving this diagnosis, it’s natural for families to have questions or concerns and even feel overwhelmed. In this situation, help in the form of information, resources, and care strategies can be critical to helping young people with MG live fulfilling and active lives.
This informative overview takes a close look at myasthenia gravis, including causes, symptoms, treatment options, and how to care for a child with this diagnosis. You’ll also learn how pediatric home health services can play a crucial role in supporting children and families across the care journey.
What Is Myasthenia Gravis (MG)?
Myasthenia gravis (MG) is a chronic autoimmune disorder that affects the neuromuscular system, causing weakness in the voluntary muscles. This condition occurs when the immune system mistakenly attacks communication between nerves and muscles, disrupting the normal transmission of signals. This results in muscle weakness that worsens with activity and improves with rest.
The condition can affect any voluntary muscle in the body, including those responsible for breathing, swallowing, and movement. In children, MG is relatively rare, but when it occurs, it often presents unique challenges for families and caregivers.
The severity of the condition can vary from one child to another, with some experiencing mild symptoms while others may have more severe forms of muscle weakness. Fortunately, with early diagnosis and appropriate treatment, many children with MG can lead relatively normal lives.
Types of Myasthenia Gravis
MG can be classified into different types based on the age of onset, the affected muscles, and the severity of the symptoms. Here are the primary categories:
- Congenital Myasthenia Gravis: This form of MG is present at birth and is typically inherited. It is caused by a genetic mutation that affects the communication between nerves and muscles. Unlike autoimmune MG, congenital MG is not the result of an immune system malfunction but rather an issue with the neuromuscular junction itself.
- Acquired Myasthenia Gravis: This is the more common form of MG in children. It occurs when the immune system produces antibodies that attack and block the acetylcholine receptors on muscle cells, preventing proper nerve-to-muscle communication. Acquired MG is further categorized into:
- Generalized MG: Affects muscles throughout the body, including those involved in eye movement, facial expression, and swallowing.
- Ocular MG: Affects only the muscles that control eye movements, leading to symptoms such as drooping eyelids or double vision.
- Juvenile Myasthenia Gravis: This term is often used to describe MG when it occurs in children and adolescents. While it shares many characteristics with adult-onset MG, juvenile MG can sometimes differ in its progression and response to treatment.
Common Symptoms of Myasthenia Gravis
The symptoms of MG can vary depending on the severity and type of the condition. Some of the most common signs to watch for in children include:
- Muscle Weakness: The hallmark symptom of MG is muscle weakness that worsens with physical activity and improves with rest. Children may have difficulty performing tasks that require sustained effort, such as climbing stairs or holding up their heads for long periods.
- Drooping Eyelids (Ptosis): One of the first signs of MG in children is often ptosis, or drooping eyelids, which can make it difficult for the child to keep their eyes fully open. This can also cause visual disturbances such as double vision.
- Difficulty Swallowing (Dysphagia): Children with MG may experience difficulty swallowing, leading to choking or coughing during meals. This can make eating and drinking more challenging and may result in poor nutrition or weight loss.
- Fatigue: Children with MG often feel unusually tired or weak after physical activity. This can significantly affect their daily life and limit their ability to participate in normal activities like playing or attending school.
- Difficulty Breathing: In more severe cases of MG, the muscles that control breathing can become weak. This can lead to respiratory difficulties, especially during physical exertion or in times of illness.
- Difficulty Speaking (Dysarthria): Weakness in the facial and throat muscles can make it hard for children with MG to speak clearly. This may result in slurred or quiet speech.
Causes and Risk Factors of Myasthenia Gravis
The exact cause of myasthenia gravis is not fully understood, but the condition is primarily thought to be an autoimmune disorder. In a healthy immune system, antibodies protect the body from infections. In children with MG, the immune system mistakenly produces antibodies that attack acetylcholine receptors on muscle cells, impairing the communication between nerves and muscles.
While the exact trigger for this immune response is unclear, certain factors may increase the risk of developing MG:
- Genetics: In rare cases, MG can be inherited, particularly in congenital MG. Certain genetic factors may make a child more susceptible to developing the condition.
- Thymus Gland Abnormalities: The thymus is an organ located behind the breastbone and is involved in the development of the immune system. Children with MG may have an abnormal thymus, such as a thymoma (a tumor in the thymus), which could contribute to immune dysfunction.
- Infections: Viral or bacterial infections may trigger the onset of MG in some children, although this is not always the case.
- Age and Gender: Although MG can develop at any age, it is more commonly diagnosed in teenagers and young adults. The disease is also more common in girls than boys in the pediatric population.
Complications of Myasthenia Gravis
Without proper management, myasthenia gravis can lead to serious complications, including:
- Respiratory Failure: Severe muscle weakness, particularly in the diaphragm and intercostal muscles, can impair breathing. If respiratory muscles become too weak, it can lead to respiratory failure, which is a medical emergency.
- Swallowing and Nutritional Problems: Difficulty swallowing can lead to malnutrition, dehydration, or food or liquid entering the airway, which increases the risk of pneumonia.
- Increased Risk of Infections: Children with MG are more susceptible to respiratory infections, as weakened muscles make it harder to clear mucus and protect the airways.
- Psychosocial Impact: The challenges of living with a chronic condition like MG can affect a child’s emotional well-being. Feelings of frustration, isolation, or anxiety are common, particularly as children may struggle to keep up with their peers in physical activities.
Diagnosis of Myasthenia Gravis
Diagnosing MG in children involves a combination of clinical examination, medical history review, and specialized tests. Doctors may perform the following:
- Physical and Neurological Examination: The doctor will assess the child’s muscle strength, reflexes, and coordination to look for signs of MG.
- Blood Tests: Blood tests can detect the presence of antibodies against acetylcholine receptors or other proteins involved in MG.
- Electromyography (EMG): This test measures the electrical activity of muscles and can help assess the neuromuscular function and diagnose MG.
- Tensilon Test: This involves administering a drug called Tensilon, which temporarily improves muscle strength in people with MG, helping to confirm the diagnosis.
- CT or MRI Scans: Imaging tests may be used to check for abnormalities in the thymus gland, which can be associated with MG.
Treatment of Myasthenia Gravis
Although there is no cure for myasthenia gravis, there are various treatments available that can help manage symptoms and improve quality of life. Treatment options include:
- Medications:
- Acetylcholinesterase Inhibitors: These drugs help increase the levels of acetylcholine at the neuromuscular junction, improving muscle strength.
- Immunosuppressive Drugs: These medications help reduce the abnormal immune response and prevent further damage to the neuromuscular junction.
- Thymectomy: In cases of thymoma or severe MG, surgical removal of the thymus may improve symptoms.
- Plasmapheresis and IVIG: In severe cases, where symptoms are life-threatening, treatments like plasmapheresis (plasma exchange) or intravenous immunoglobulin (IVIG) may be used to remove harmful antibodies from the blood.
- Physical and Occupational Therapy: Working with a physical therapist or occupational therapist can help children with MG maintain muscle strength, improve coordination, and develop coping strategies for daily activities.
