Understanding and Treating Myasthenia Gravis Headaches

Understanding Myasthenia Gravis Headaches

Myasthenia gravis is an autoimmune disease that leads to muscle weakness and fatigue. Headaches are a common symptom, affecting up to 60% of people with myasthenia gravis. These headaches can range from mild to severe in intensity and have multiple causes.

Some key facts about myasthenia gravis headaches:

• They may be localized or generalized.
• They can occur on one or both sides of the head.
• Pain levels can fluctuate daily or weekly.
• Triggers include stress, weather changes, bright lights, noises, and fatigue.
• Women report more frequent and severe headache pain.

Understanding the type and cause of your myasthenia gravis headaches is key to finding effective treatment options. Headaches associated with this condition generally fall into three categories:

Muscle Tension Headaches

The weakness caused by myasthenia gravis can make the muscles in the neck and scalp tense or tight. This muscle tension can trigger headache pain. These types of headaches cause a pressing, squeezing pain on both sides of the head.

Migraine Headaches

Migraines are severe headaches that can involve nausea, light and sound sensitivity, and throbbing pain. Research indicates migraines are more common in people with myasthenia gravis than the general population.

Medication Side Effect Headaches

Some medications used to treat myasthenia gravis can potentially cause headaches as a side effect. Mestinon or pyridostigmine, immunsuppressants, steroids, and intravenous immunoglobulin (IVIG) infusions may trigger headaches in some patients.

Myasthenia Gravis Headache Triggers

There are a number of potential triggers that can set off headache pain for people with myasthenia gravis:

• Stress - Physical or emotional stress can trigger both tension and migraine headaches.
• Hormones - Women may experience more frequent headaches associated with menstrual cycles.
• Weather Changes - Barometric pressure shifts from storms, cold fronts, or heat waves can trigger migraines.
• Sleep Problems - Lack of sleep, changes in sleep cycle, and sleep apnea are headache triggers.
• Low Blood Sugar - Infrequent meals or going too long without eating can set off a headache.
• Dehydration - Not drinking enough fluids can cause headache pain.
• Bright Lights - Photophobia or light sensitivity is common with myasthenia gravis headaches.
• Noises - Loud sounds or environments can increase headaches.
• Medications - Some myasthenia gravis drugs directly cause headaches as a side effect.
• Too Much Activity - Overexertion and muscle fatigue often precede a tension headache.

Myasthenia Gravis Headache Treatments

Finding the right headache treatment will depend on the specific cause and type. Here are some of the most effective options for managing myasthenia gravis headache pain:

Over-the-Counter Medications

OTC medications like acetaminophen (Tylenol), ibuprofen (Advil, Motrin), and naproxen (Aleve) can help relieve headache pain. Avoid overusing these medications to prevent medication overuse headaches.

Migraine Medications

For moderate to severe migraine pain, prescription medications like sumatriptan (Imitrex) and rizatriptan (Maxalt) can relieve symptoms. Ergotamine medications are not recommended for myasthenia gravis patients.

Muscle Relaxers

Muscle relaxants like cyclobenzaprine (Flexeril) or tizanidine (Zanaflex) can relieve muscle tension and spasms that trigger headaches.

Massage and Physical Therapy

Hands-on treatments like massage, trigger point therapy, gentle chiropractic adjustment, and physical therapy stretches can ease muscle tension headaches.

Heat or Ice Packs

Applying a warm compress or cold pack to painful headache muscles can help interrupt the pain signals.

Rest in a Dark Room

At the first sign of a migraine, resting in a quiet, dark room can sometimes stop the attack. Limit sensory input to help ease headache pain.

IVIG Therapy

For severe myasthenia gravis headaches not relieved by other treatments, IVIG immunotherapy may reduce frequency and severity of headaches.

Neuromodulation Devices

Devices like Cefaly and Nerivio emit electrical signals that can interrupt pain pathways in the brain and block migraine headaches.

Relaxation Techniques

Biofeedback, meditation, guided imagery, deep breathing exercises, and progressive muscle relaxation help relieve stress that can trigger tension and migraine headaches.

Acupuncture

Acupuncture treatments can reduce migraine and tension headache frequency and restore energy balance to the body.

Lifestyle Changes to Prevent Headaches

Making certain lifestyle adjustments and adopting better habits can help prevent myasthenia gravis headache triggers:

• Get adequate sleep and stick to consistent sleep/wake times.
• Schedule meals and snacks every 3-4 hours to maintain blood sugar.
• Drink at least 8 glasses of water daily to stay hydrated.
• Limit caffeinated and alcoholic beverages which can trigger migraines.
• Reduce stress through relaxation techniques, humor, social support, counseling, and time management.
• Exercise regularly to increase oxygen and endorphin levels.
• Identify and avoid foods, odors, chemicals, or other headache triggers.
• Use sunglasses, hats, and filter screens to reduce exposure to bright light.
• Apply hot or cold compresses to neck and shoulder muscles for tension relief.

Making headache trigger avoidance, stress management, and healthy lifestyle choices a daily habit can significantly reduce headache occurrences.

When to See a Doctor for Headaches

Consult your doctor promptly if you experience:

• Sudden or severe headache pain unlike prior headaches
• Headaches that worsen despite taking medication
• New headache symptoms like speech problems, confusion, or vision loss
• Headaches that prevent normal functioning
• Daily persistent headache pain

Seek emergency care if you have extremely severe headache pain along with fever, stiff neck, nausea/vomiting, convulsions, fainting, or sudden neurological symptoms.

Getting an accurate headache diagnosis and tailored treatment plan from your doctor can help minimize the impact of headache pain on your daily life.

Outlook for Controlling Myasthenia Gravis Headaches

While headaches can be a bothersome aspect of living with myasthenia gravis, there are many effective options available to prevent and treat headache pain episodes.

Identifying your specific headache triggers and making lifestyle modifications can significantly reduce your risk. When headaches do occur, using medications, massage, rest, and relaxation techniques can provide relief.

Working closely with your neurologist to find the right headache management plan helps ensure myasthenia gravis doesnt have to mean living with constant head pain. With proper treatment, most people living with this condition can keep headaches well controlled and infrequent.
