Myasthenia gravis is a rare autoimmune disease that affects around 12 in 100,000 people worldwide. Recently, former tennis champion Monica Seles revealed she has been living with this condition for the past few years. The disease disrupts the communication between the nerves and muscles, leading to muscle weakness that worsens with activity and improves with rest.
Symptoms and Early Signs
The symptoms of myasthenia gravis can appear suddenly and may vary from person to person. In Seles’ case, the first signs of the disease began around three years ago, including double vision and general weakness in her arms and legs. These symptoms made everyday activities, like drying her hair, a struggle.
Muscle weakness can affect crucial body functions such as walking, speaking, breathing, and swallowing. One of the most common symptoms is drooping eyelids and double vision, particularly in the early stages. In severe cases, the disease can cause respiratory problems, leading to a myasthenic crisis that may require hospitalization or life support.
Real-Life Experiences of Myasthenia Gravis
People living with myasthenia gravis often describe how the disease can disrupt their lives in unexpected ways. For example, a woman in her 30s recounted how her speech slows during a crisis, and she sometimes struggles to breathe, unable to communicate the severity of her condition. “Having my mum there to advocate for me has been life-saving,” she explained.
Similarly, a man in his 70s shared how the disease started suddenly during a speech at his 70th birthday party. His family initially thought he was having a stroke, illustrating just how quickly myasthenia gravis can manifest.
Causes and Risk Factors
The exact cause of myasthenia gravis remains unclear, but it is not considered to be hereditary. However, there is evidence suggesting it may be more common in people who also have other autoimmune diseases, such as autoimmune thyroid disease, lupus, or rheumatoid arthritis.
Myasthenia gravis can develop at any age, though it tends to affect women under 40 (early onset) and men over 60 (late onset).
Diagnosing Myasthenia Gravis
Diagnosing myasthenia gravis can be challenging because its symptoms overlap with those of other conditions. Doctors rely on clinical judgment, supported by various tests such as blood tests for antibodies, nerve conduction studies, and electromyography. However, these tests are not foolproof, and the disease often remains under-recognized.
Treatment Options for Myasthenia Gravis
Currently, there is no cure for myasthenia gravis, but treatments are available to manage symptoms and improve quality of life. These treatments include:
- Anticholinesterase inhibitors: Oral medications that temporarily enhance communication between nerves and muscles.
- Immunosuppressants: Medications that reduce the immune system’s attack on the body’s muscles.
- Plasma exchange and intravenous immunoglobulin (IVIg): These therapies remove or block harmful antibodies, requiring hospital admission for administration.
- Surgery: In some cases, removal of the thymus gland can help reduce symptoms.
While most treatments are subsidized, access remains a challenge, particularly for patients in remote areas where resources like plasma exchange or IVIg are not available.
Long-Term Outlook for Those with Myasthenia Gravis
While myasthenic crises can be life-threatening, the overall prognosis for most people with myasthenia gravis is positive. Life expectancy is generally not significantly affected, although the disease can vary greatly in severity from person to person. Some people may experience minimal symptoms, requiring little to no treatment, while others may require frequent hospitalizations.
As one woman in her 60s, who has lived with myasthenia gravis for a decade, put it, “You never know what each day will bring.”
