Symptoms of Myasthenic Crisis (Myasthenia Gravis Crisis)

Common Symptoms

A myasthenic crisis is a serious condition that can develop in people with myasthenia gravis. It is important to recognize the symptoms of a myasthenic crisis and seek medical help right away. Here are some common symptoms of a myasthenic crisis:

Difficulty breathing: This can be characterized by shallow breathing and weak cough.
General weakness: You may experience overall weakness in your body.
Weakness in limbs: Your arms and legs may feel weak.
Bulbar weakness: This refers to weakness in the muscles involved in speech, swallowing, and other functions. It may cause drooling, lip trembling, loss of gag reflex, tongue or jaw weakness, difficulty swallowing or talking, and a nasal or hoarse voice.

If you think you may be developing or experiencing a myasthenic crisis, it is important to seek medical help right away. Early treatment is crucial to improve your outcome. Here are some ways to treat and mitigate the symptoms of a myasthenic crisis:

Seek medical help: Contact your healthcare provider or go to the nearest hospital if you suspect a myasthenic crisis.
Intensive care unit (ICU) treatment: You will likely receive treatment in the ICU of a hospital. This allows for close monitoring and immediate intervention if necessary.
Breathing support: If your breathing is compromised, you may need assistance with breathing. This can involve inserting a tube into your windpipe (intubation) and using a ventilator machine to provide breathing support.
Medications: Your healthcare provider may prescribe medications to open your airways, alter your immune system, or manage symptoms associated with the crisis.
Plasma exchange or intravenous immunoglobulin: These treatments temporarily alter your immune system by replacing harmful immune proteins with healthy donor proteins.
Fluids and dietary supplements: To keep you hydrated and meet your nutritional needs during the crisis.
Rehabilitation therapy: After leaving the hospital, your doctor may prescribe rehabilitation therapy or refer you to specialists such as respiratory therapists. These therapies can support your recovery.

It's important to follow your treatment plan for myasthenia gravis to reduce the risk of a myasthenic crisis. Taking steps to avoid potential triggers, such as respiratory infections, can also help lower your risk. Remember that early treatment for symptoms of a myasthenic crisis can help limit its severity and promote recovery.

Common Symptoms in More Severe Disease

A myasthenic crisis is a serious condition that can develop over several hours, days, or weeks. However, in some cases, it can progress more quickly. Here are the symptoms of a more severe or progressed myasthenic crisis:

Difficulty breathing: This is a common symptom of a myasthenic crisis. It can be characterized by shallow breathing and weak cough.
General weakness: People experiencing a myasthenic crisis may feel overall weakness in their body.
Weakness in limbs: Limbs, such as arms and legs, may feel weak and lack strength.
Increased bulbar weakness: Bulbar weakness refers to weakness in the muscles responsible for speech, swallowing, and other functions. In a myasthenic crisis, bulbar weakness may become more pronounced. This can lead to symptoms such as drooling, lip trembling, loss of gag reflex, tongue or jaw weakness, difficulty swallowing or talking, nasal or hoarse voice.

If you suspect that you are developing or experiencing a myasthenic crisis, it is important to seek medical help right away. Early treatment is crucial to improve outcomes.

To treat or mitigate the symptoms of a myasthenic crisis, here are some steps you can take:

Follow your treatment plan for myasthenia gravis: By adhering to the treatment plan prescribed by your doctor, you can reduce the risk of a myasthenic crisis.
Take medication and other treatments as prescribed: Your doctor may prescribe medications and other treatments to manage your myasthenia gravis. It is important to take them as directed.
Manage potential triggers: Taking steps to avoid or manage potential triggers can help reduce the risk of a myasthenic crisis. For example:
Lower your risk of respiratory infections by getting recommended vaccinations, avoiding close contact with sick people, and practicing good hand hygiene.
Before making any changes to your medications, undergoing surgery, getting pregnant, or giving birth, consult with your doctor on how to manage the risk of a myasthenic crisis.
Take steps to limit preventable injuries and stress.
Seek early treatment for symptoms: If you notice symptoms of a myasthenic crisis, it is important to seek early medical treatment. This can help limit the severity of the crisis and promote recovery.

In the event of a myasthenic crisis, you will likely receive treatment in the intensive care unit (ICU) of a hospital. Treatment may include:

Insertion of a tube into your windpipe (intubation) to secure your airway
Breathing support from a ventilator
Breathing exercises to improve lung function
Airway suctioning to remove mucus and secretions
Medication to open airways, alter the immune system, or manage symptoms
Plasma exchange or intravenous immunoglobulin therapy to temporarily alter the immune system
Fluids and dietary supplements to maintain hydration and meet nutritional needs

Your care team will monitor you for complications and provide appropriate treatments as needed. After leaving the hospital, rehabilitation therapy and psychological counseling may be recommended to support your recovery from a myasthenic crisis.

Remember that seeking medical help promptly and following your doctor's guidance are crucial in managing and mitigating the symptoms of a myasthenic crisis.

Symptoms of a Condition Flare-up

A flare-up or exacerbation of myasthenic crisis can cause various symptoms. Here are the symptoms to watch out for:

Difficulty breathing: This can include shallow breathing and weak cough.
General weakness: You may feel weak all over your body, including your limbs.
Increased bulbar weakness: This can cause specific symptoms like drooling, lip trembling, loss of gag reflex, tongue or jaw weakness, difficulty swallowing or talking, and a nasal or hoarse voice.

If you think you may be experiencing a flare-up of myasthenic crisis, it is important to seek medical help right away. Early treatment is crucial for improving your outcome.

Now let's talk about how to treat a flare-up of myasthenic crisis:

Seek medical help: As mentioned earlier, it's important to reach out to healthcare professionals as soon as possible.
Respiratory support: Myasthenic crises can lead to respiratory failure, so respiratory support may be necessary. In the early phase of respiratory failure, non-invasive ventilation may be an option. However, if there is established infection and atelectasis (partial collapse of the lung), endotracheal intubation (a tube inserted into the windpipe) is likely needed.
Identify potential triggers: It's essential to identify any potential triggers that may have contributed to the flare-up. This includes screening for underlying infections, such as aspiration pneumonia. Recent changes in medications should also be noted since certain medications can exacerbate myasthenic symptoms.
Assess recent dose adjustments and compliance with myasthenia therapy: Rapid up-titration (increasing the dose) or withdrawal of myasthenia therapy can trigger a flare-up of symptoms. Therefore, it's important to assess recent dose adjustments and ensure compliance with the prescribed treatment plan.

Remember, treating a flare-up of myasthenic crisis requires prompt medical attention and close monitoring by healthcare professionals. By seeking timely help and following the recommended treatment steps, you can improve your chances of managing the flare-up effectively.

Warning Signs

If you experience any of the following warning signs of a myasthenic crisis, it is important to seek medical help right away:

Difficulty breathing: This may include shallow breathing or feeling like you can't catch your breath.
Weak cough: If you have a weak cough or are having trouble coughing, it could be a sign of a myasthenic crisis.
General weakness: If you feel weak all over and have difficulty moving or performing daily activities, it may be a symptom of a myasthenic crisis.
Weakness in your limbs: If you notice weakness in your arms or legs, it could be a sign of a myasthenic crisis.
Increased bulbar weakness: This refers to weakness in the muscles involved in speech and swallowing. Signs may include drooling, lip trembling, loss of gag reflex, tongue or jaw weakness, difficulty swallowing or talking, and a nasal or hoarse voice.

Remember, early treatment is important to improve your outcome. So if you think you may be developing or experiencing a myasthenic crisis, don't hesitate to seek medical help.
