Facial Twitching and Multiple Sclerosis

Signs of MS Facial Twitching

It might begin as one thing we’re all aware of: tiny spasms round your eyelid.

“Once you’re drained or careworn and also you get fluttering beneath your eye or eyelid and it’s actually annoying,” says Sharon Stoll, DO, a neurologist and MS specialist with Yale Medication. And for most individuals, that’s so far as it goes.

However when this twitching is from multiple sclerosis (MS), this facial twitching might unfold. It’d go down your cheek to your mouth or jawline. And it occurs extra usually. “It’s occurring a number of occasions a day,” says Oliver Tobin, MB, a neurologist who makes a speciality of MS on the Mayo Clinic.

Normally, MS facial twitching impacts one facet of your face at a time. And you might discover different facial signs first, like numbness, tingling, weak spot, or different bizarre sensations.

“Individuals will often say, ‘My face feels swollen, however I look within the mirror and it’s not swollen,’” Stoll says. “And the spasms will occur months later.”

Completely different Forms of MS Facial Twitching

Even for individuals who have MS, an occasional eyelid tremble, by itself, often has nothing to do with the illness. However in some circumstances, it is perhaps an indication of a bigger challenge associated to MS, together with:

Steady facial myokymia: This may really feel form of like an eyelid twitch (myokymia). However you’ll get ongoing spasms in different areas, similar to your brow, cheek, mouth, and chin.

These twinges are comparatively widespread in individuals who have MS. And so they’re often short-lived and painless. However they are often uncomfortable. “It simply feels bizarre,” Tobin says.

Hemifacial spasm: In comparison with facial myokymia, these are longer-lasting contractions.

Sturdy facial spasms might power your eyelid closed or pull your mouth to 1 facet. It’s possible you’ll really feel a number of tightness, Tobin says. Sooner or later, all of the muscle groups on one facet of your face could also be concerned. It might appear to be you’re having a seizure.

It’s uncommon for MS to trigger hemifacial spasm. Stoll hardly sees it in her observe. But when it occurs to you, it tends to be extra extreme and lifestyle-limiting than facial myokymia.

“Think about if half your face is spasming on a regular basis,” she says. “You’ll be able to’t eat. You’ll be able to’t speak.”

What Causes MS Facial Twitching?

When you might have MS, your immune system breaks down myelin. That’s the protecting cowl round your nerves. With out this insulation, it’s arduous for alerts to journey out of your mind to your muscle groups the way in which they need to.

Most individuals with MS facial twitching have a lesion in a sure a part of the brainstem referred to as the pons. Necessary nerves go out and in of this bony canal. Docs usually discover harm to the seventh cranial nerve, higher referred to as the facial nerve.

Just like the title suggests, your facial nerve controls your facial muscle groups. (It additionally performs an element in how a few of your style buds work.)

It’s unclear precisely how MS lesions trigger facial twitching. We’d like extra analysis to search out out. However scientists have some theories, together with:

Ephaptic transmission: Nerve impulses inform your physique the best way to transfer. However a scarcity of myelin could make your nerves glitchy. And when you might have two broken (demyelinated) nerves proper subsequent to one another, {the electrical} sign from one can set off the opposite.

“It’s primarily like a leaky present,” Tobin says.

Listed below are some examples of ephaptic transmission that you simply is perhaps aware of:

Lhermitte’s signal: You bend your neck and get a buzzing sensation down your physique. It might be an indication of MS, however it might probably occur to anybody.Tonic spasms: You go to face or transfer your physique and get painful muscle contractions in your arms or legs. These spasms often final 60 to 90 seconds.

Nerve hyperexcitability: Your facial nerve might hearth greater than it ought to. Some scientists assume hyperexcitability from different areas might trigger MS facial twitching even if you happen to don’t have a visual lesion within the pons of your brain stem.

How Do You Diagnose MS Facial Twitching?

Not like different MS symptoms, steady facial myokymia and hemifacial spasm is probably not an indication of a brand new lesion.

Nonetheless, your physician will need some new footage of your mind to make certain. Up to date MRI scans can provide sturdy clues about whether or not your MS is well-controlled otherwise you’re having a relapse.

You might also get a particular nerve take a look at. That is referred to as an electromyography (EMG). It’ll measure the timing of your muscle spasms. It is a good strategy to inform the distinction between facial myokymia (brief spasms) and hemifacial spasm (extended spasms).

Your physician might order blood work or further exams to rule out different well being situations. You’ll be able to have facial twitching for a lot of causes unrelated to MS, together with inflammation or an infection.

Your facial twitches is perhaps idiopathic. Meaning “there’s no actual connection” to any medical challenge, Stoll says.

Therapy for MS Facial Twitching

It’s possible you’ll not must do something besides wait. Facial twitching usually resolves by itself after a couple of weeks or months. That’s very true for facial myokymia, Tobin says.

MS-related hemifacial spasm additionally tends to ease over time. However it could take years. And a few individuals might have these spasms for the remainder of their life.

The excellent news is you will get assist in your signs irrespective of how brief or lengthy they final.

Therapy for MS facial twitching contains:

Botox: Botulinum toxin can quickly paralyze facial muscle groups. That’s the way it eliminates wrinkles. However it’s additionally the simplest strategy to cease severe facial twitches.

Botox may also help individuals with hemifacial spasm “get their lives again,” Stoll says.

You’ll usually want pictures each 3 months till your spasms cease. Ask your physician to refer you to a neurologist who usually treats hemifacial spasm. They’ll assist you determine when it’s secure to begin and cease therapy.

Different medicines: Your physician might have you ever attempt different drug therapies. For gentle facial twitching, that may embody

Life-style modifications: MS facial twitching isn’t your fault. “However it’s extra prone to reappear with stress and fatigue,” Stoll says.

When to See Your Physician

Random eyelid twitches are often nothing to fret about.

However test in along with your neurologist if different facial muscle groups begin to spasm. Name them straight away in case your twitches are new and final for greater than 24 hours. “That’s true for any symptom from a number of sclerosis,” Stoll says.

MS facial twitching often goes away in some unspecified time in the future. And when that occurs, you might surprise: Will it come again?

“That’s a superb query. I don’t assume we actually know,” Tobin says. “But when it’s gone for per week or two, then it’s in all probability gone.”
