Here are the common causes of myokymia, along with suggested treatment methods: Stress – Along with lack of sleep, stress is a leading cause of this condition. Relaxation methods like yoga and deep breathing can help manage stress and allow you to sleep more soundly.
What is the focus of treatment for myokymia?
Treatment of myokymia is focused largely on the underlying etiology. Most patients with facial or focal limb myokymia are not particularly disturbed by the myokymia itself. The accompanying symptoms of the particular neurological or medical conditions are the major concern to patients and their caretakers.
Can myokymia be caused by other illnesses?
Myokymia is rarely the result of an underlying illness. Although it may be present alongside some other conditions — including mini stroke (transient ischemic attack or TIA), Parkinson’s disease and multiple sclerosis (MS) — these are very unlikely to cause eye twitching in the average person. SEE RELATED: Eye twitching: Alarming or harmless?
What causes Myokymia in sleep?
Myokymia describes fine quivering, rippling, and undulating contractions of parts of muscle fascicles that is often triggered or exacerbated by stress, sleep deprivation, and caffeine and may persist during sleep. They are caused by hyperexcitability of peripheral nerve motor axons (Gutmann and Gutmann, 2004 ).
What is myokymia and synkinesis?
Myokymia and synkinesis. This is seen predominantly with disease of the anterior horn cells and presents as low-amplitude intermittent twitching of muscles, due to motor unit discharges, which are usually not strong enough to move a joint, although this can occur, particularly in children.
Is myokymia caused by stress?
Myokymia of the lid is a unilateral and uncontrollable lid twitch or tic that is not caused by disease or pathology. Myokymia is thought to be brought on by stress and other similar issues and resolves on its own with time. It usually involves the lower eyelid and is self-limiting to a few days or a week.
Will myokymia go away?
Myokymia is commonly used to describe an involuntary eyelid muscle contraction, typically involving the lower eyelid or less often the upper eyelid. It occurs in normal individuals and typically starts and disappears spontaneously. However, it can sometimes last up to three weeks.

Eyelid twitching (myokymia) affects only the eyelid. This type of twitch or spasm is very common and happens to most people at one time or another. It can involve either the upper or lower lid, but usually only one eye at a time.
Can anxiety cause eye twitching?
Minor eyelid twitching can be linked to everyday occurrences, including stress or anxiety. This is typically because you feel more tense, which can cause the muscles and nerves around your eye to become overstimulated.
Do screens cause eye twitching?
Overuse of computers, tablets, and smartphones is a cause of eye strain, which in turn triggers eyelid twitching. To avoid straining your eyes, use the 20-20-20 rule: every 20 minutes, look away from your screen and focus on an object at least 20 feet away for 20 seconds.
Can myokymia last for years?
The mean duration of symptoms at first examination was 91 months (range 2.5 months to 20 years). In no patient was the myokymia the first manifestation of a neurologic disease, although one patient progressed to ipsilateral hemifacial spasm. Thirteen patients (86.7%) underwent neuroimaging that gave negative results.
Should I be worried about myokymia?
An eye/eyelid twitch (myokymia), is an involuntary, repeated spasm of the eyelid muscle. It can occur in the upper or lower lids. It is usually harmless and resolves without any treatment. The twitching or spasms are usually very mild and feel like a gentle tug or flickering of the eyelid.

What is myokymia associated with?
Myokymia is often associated with demyelination of axons either in the intraaxial (e.g., multiple sclerosis) or peripheral (e.g., Guillain−Barré syndrome, chronic inflammatory demyelinating polyneuropathy) portion of the peripheral nerve.
What is myokymia in the brain?
Myokymia is a type of abnormal spontaneous electrical activity characterized by grouped discharges of motor unit action potentials. Myokymia originates from areas of axonal demyelination. The audio signal of myokymia is ‘marching.’ The principal clinical feature of myokymia is continuous involuntary rippling (worm-like) movements of muscle. Myokymia most commonly occurs as either facial or limb myokymia. Facial myokymia may be seen in Guillain–Barre syndrome or brainstem lesions, whereas limb myokymia is observed with radiation plexitis. Treatment of myokymia is usually unnecessary as it is asymptomatic or self-limited.

Myokymia occurs in diseases of motor axons. Generalized myokymia may occur in Guillain-Barré syndrome and HMSNs and is a central feature of the peripheral nerve hyperexcitability syndromes associated with neuromyotonia and delayed muscle relaxation.
Why does myokymia twitch?
But because the eyelids are so thin, myokymia has the appearance of an eyelid twitch rather than the undulating skin movements common to facial or limb myokymia. Myokymia may be observed in both peripheral nervous system and central nervous system disorders. Clinical myokymia may appear in several patterns of distribution: 1.
How long does myokymia last?
When due to multiple sclerosis, facial myokymia tends to abate after weeks or months. When due to a pontine glioma, facial myokymia may persist indefinitely and can be associated with facial contracture (Video 1.68). Myokymia is also a feature of neuromyotonia (see under “Stiff muscles,” earlier in this chapter).

Myokymia and neuromyotonia. Myokymia app lies to undulating worm-like localized movements in affected muscles. Myokymia can arise in proximal axons within the CNS, as observed in facial myokymia in multiple sclerosis, and following root lesions or nerve injuries.
What is the continuous undulation of a group of muscle fibers caused by the successive spontaneous contraction of motor units?
Myokymia is the continuous undulation of a group of muscle fibers caused by the successive spontaneous contraction of motor units. On EMG, they appear as groups of 2 to 10 potentials, firing at 5 to 60 Hz and recurring regularly at 0.2- to 1-second intervals. Myokymia, frequently observed in facial muscles, occurs in a number of brain stem diseases, especially multiple sclerosis, radiation-induced nerve damage, Guillain-Barré syndrome, chronic peripheral nerve disorders, timber rattlesnake envenomation, gold therapy, and Isaacs’ syndrome.

How does myokymia affect sensory neurons?
Muscular movements are controlled through signals from the motor neurons, whereas sensations are elicited through sensory neurons. Myokymia mostly affects the motor neurons, and causes a variety of signs and symptoms related to muscular movements. Sensory neurons are rarely affected. The following are the general symptoms that are commonly seen in all types of myokymia:
What are the different types of myokymia?
Based on the affected muscle groups, myokymia is generally classified into four broad categories. These include the following: Facial myokymia: Facial myokymia affects the muscles of the face. Eyelid myokymia: Eyelid myokymia affects the muscles that control the movements of the eyelids.
How are muscles controlled?
The movements of muscles in the body are controlled through the action of various nerves that emanate from the brain and the spinal cord. A single nerve can innervate multiple muscles and coordinate their contractions and relaxations. In myokymia, skeletal muscles of the body undergo involuntary contractions.
What causes facial myokymia?
Potential causes of facial myokymia include nerve demyelination, brain damage, and tumors in the brainstem. Facial myokymia could also result from Guillain-Barre´ syndrome.

Myokymia produces an abduction and adduction tremor of the fingers when the arm is bitten or a vertical tremor of the toes when the leg is attacked, each of which typically resolves over 3 days ( 17 ). Persistent facial myokymia may also be a focal manifestation of K+ channel antibody syndrome ( 20 ).
What is myokymia in the cerebellum?
Myokymia is also an important feature of episodic ataxia type 1, which is caused by mutations of the voltage-gated potassium channel, KCNA1, with high expression in the basket cells of the cerebellum and in the axons of peripheral nerves. Some individuals with this mutation have had isolated neuromyotonia ( 07; 52 ).
What is neuromyotonia and myokymia?
Neuromyotonia and myokymia are related disorders of peripheral nerve hyperexcitability. Clinically they manifest as muscle stiffness and twitching. Both conditions are typically related to disorders of the voltage-gated potassium channel and caused by autoimmune, toxic, or genetic processes.

• Generalized neuromyotonia is usually an autoimmune disease characterized by widespread muscle stiffness and delayed muscle relaxation after voluntary movement. It is accompanied by continuous muscle twitching known as myokymia.
How long does neuromyotonia last?
Electrical neuromyotonia consists of irregular high-frequency (150 to 300 Hz) trains of decrementing single motor unit discharges, which usually start and stop suddenly and can last for up to several seconds. The decrement in amplitude occurs within the train, although the train starts and stops abruptly.
What is the name of the condition that is characterized by impaired muscle relaxation?
Originally described by Gamstorp and Wohlfart in 1959, it has also been called "Isaacs syndrome" ( 28) and "myokymia with impaired muscle relaxation" ( 15 ), but it is now mostly called "neuromyotonia" ( 39 ).
