1,130 Possible Causes for Myokymia

  • Episodic Ataxia

    In addition, myokymia (rippling of muscles, diagnosable by electromyography) is evident during and between attacks.[] All of the affected family members had episodes typically lasting for several hours, and none of them had muscle abnormalities including myokymia.[] Episodic ataxia and myokymia syndrome is an autosomal dominant disorder characterized by persistent myokymia and attacks of unsteadiness, slurred speech, and tremulousness[]

  • Myotonic Syndrome

    Neuromyotonia and myokymia Robert Layzer MD (Dr. Layzer of the University of California, San Francisco, has no relevant financial relationships to disclose.)[] Fibrillations and myokymia may also occur. Neuromyotonia NMT a.k.a.[] Facial myokymia in multiple sclerosis. Brain. 1961. 84:31-44. Blunt SB, Khalil NM, Perkin GD. Facial myokymia in multiple system atrophy.[]

  • Drug-induced Myopathy

    A 26-year-old man, who had started treatment for pulmonary tuberculosis, developed polyarthralgia, generalised myalgia, weakness, and elevated uric acid and creatine kinase levels. His polyarthralgia improved on cessation of pyrazinamide, but the improvement in his myalgia and creatine kinase was delayed. Drug-induced[…][]

  • Facial Spasm

    One type is superior oblique myokymia .[] Facial myokymia - Myokymia is the spontaneous, fine fascicular contractions of muscle without muscular atrophy or weakness.[] Facial myokymia Facial myokymia appears as vermicular twitching under the skin, often with a wavelike spread.[]

  • Familial Dyskinesia and Facial Myokymia

    No other disorders primarily characterized by myokymia, dystonia, or chorea are known to map to this region.[] […] choreiform and that are associated with perioral and periorbital myokymia.[] Familial dyskinesia with facial myokymia (FDFM) is an autosomal dominant disorder that is exacerbated by anxiety.[]

  • Hemifacial Spasm

    RESULTS: Facial myokymia was associated with a clinical or radiologic relapse in 11 of 28 patients.[] It is important to distinguish this from other causes of facial spasms, such as psychogenic facial spasm, facial tic, facial myokymia, blepharospasm, and tardive dyskinesia[] HFS needs to be differentiated from other causes of facial spasms, such as facial tic, ocular myokymia, and blepharospasm.[]

  • Blepharospasm

    Blepharospasm may be differentiated from conditions like: Ocular myokymia: Ocular myokymia is characterised by spontaneous, fine fascicular contractions of orbicularis oculi[] The condition should be distinguished from the more common, and milder, involuntary quivering of an eyelid, known as myokymia.[] […] of the lid or eye (e.g. blepharitis, dry eyes, corneal foreign body) Differential diagnosis: hemifascial spasms — idiopathic or a brainstem lesion; may need an MRI eyelid myokymia[]

  • Multifocal Motor Neuropathy

    The paretic muscles showed abundant fasciculations and myokymia but only little amyotrophy.[] "Motor neuropathy with proximal multifocal persistent conduction block, fasciculations and myokymia. Evolution to tetraplegia".[]

  • Insomnia

    The findings included fasciculations as well as myokymia, doublets and multiplets, high frequency discharges, and afterdischarges, following motor nerve stimulation.[]

  • Spinocerebellar Ataxia Type 5

    […] mutation (transition C T at nucleotide position 1438), the proband having a much more severe phenotype with global developmental delay, hypotonia, tremor, nystagmus, and facial myokymia[] Facial myokymia is a prominent feature among the French kindred. Nystagmus is less prominent than in SCA6 or SCA8.[]
